Divertículo de Meckel complicado. Experiencia de 15 años en un hospital interzonal / Complicated Meckel's diverticulum. Fifteen years of experiencein an interzonal hospital in the Province of Buenos Aires

Introducción: el divertículo de Meckel es la anomalía congénita más frecuente del tracto gastrointestinal. Puede presentarse con hemorragia, obstrucción intestinal o diverticulitis, complicaciones que disminuyen con la edad, por lo que en el adulto el diagnóstico suele ser incidental. El tratamiento de las complicaciones es quirúrgico, mediante diverticulectomía o resección segmentaria del intestino delgado, dependiendo de sus características morfológicas. Objetivo: analizar nuestra experiencia en el manejo del divertículo de Meckel complicado en un período de 15 años. Diseño: estudio descriptivo, observacional, transversal, retrospectivo. Material y métodos: se revisaron las historias clínicas de los pacientes operados por divertículo de Meckel complicado en el Servicio de Cirugía General del Hospital San Roque durante el periodo 2007-2022. Se registraron datos demográficos, presentación clínica, diagnóstico preoperatorio, tratamiento quirúrgico, complicaciones postoperatorias y hallazgos histopatológicos. Resultados: se incluyeron 25 pacientes, 21 (84%) hombres, 3 menores de 18 años. La presentación clínica fue un síndrome de fosa iliaca derecha en el 80% de los casos, obstrucción intestinal en el 16% y hemorragia en el 4%. En solo 2 casos se realizó el diagnóstico preoperatorio, confirmado mediante tomografía computada. Se realizó diverticulectomía en el 68% de los pacientes y resección segmentaria el 32%. El abordaje fue laparotómico en el 64%, principalmente en el periodo inicial y laparoscópico en el 36%. Hubo una complicación IIIb de Clavien-Dindo en un paciente pediátrico tratado con drenaje percutáneo. En un solo paciente (4%), que se presentó con hemorragia digestiva masiva, se encontró epitelio de tipo gástrico y páncreas ectópico en el divertículo. Conclusiones: En nuestra experiencia el divertículo de Meckel complicado se presentó predominantemente en hombres. La complicación más frecuente en el adulto fue la diverticulitis. El diagnóstico preoperatorio fue infrecuente y realizado por tomografía computada. La diverticulectomía es suficiente en la mayoría de los casos. Actualmente, la laparoscopia es una herramienta segura, rentable y eficiente que permite el diagnóstico y tratamiento oportunos de esta entidad. (AU)

Introduction: Meckel's diverticulum is the most common congenital malformation of the gastrointestinal tract. It can present with bleeding, intesti-nal obstruction or diverticulitis, complications that decrease with age, so in adults the diagnosis is usually incidental. Treatment of complications is surgical, through diverticulectomy or segmental resection of the small intestine, depending on its morphological characteristics. Objective: to analyze our experience in the management of complicated Meckel's diverticulum over a period of 15 years. Design: descriptive, observational, cross-sectional, retrospective study. Materials and methods: the medical records of patients operated on for complicated Meckel's diverticulum in the General Surgery Service of the San Roque Hospital during the period 2007-2022 were reviewed. Demo-graphic data, clinical presentation, preoperative diagnosis, surgical treatment, postoperative complications, and histopathological findings were recorded. Results: twenty-five patients were included, 21 (84%) men, 3 under 18 years of age. The clinical presentation was a right iliac fossa syndrome in 80% of cases, intestinal obstruction in 16% and hemorrhage in 4%. In only 2 cases was the preoperative diagnosis made, confirmed by computed tomography. Diverticulectomy was performed in 68% of patients and segmental resection in 32%. The approach was by laparotomy in 64%, mainly in the initial period, and by laparoscopy in 36%. There was a Clavien-Dindo IIIb complication in a pediatric patient treated with percutaneous drain-age. In only one patient (4%), who presented with massive gastrointestinal bleeding, gastric-type epithelium and ectopic pancreas were found in the diverticulum. Conclusions: In our experience, complicated Meckel's diverticulum occurred predominantly in men. The most frequent complication in adults was diverticulitis. Preoperative diagnosis was infrequent and was made by computed tomography. Diverticulectomy is sufficient in most cases. Currently, laparoscopy is a safe, profitable and efficient tool that allows for the timely diagnosis and treatment of this entity. (AU)

Cohorte descriptiva de pacientes adultos con hipertensión portal en una institución de tercer nivel en Colombia / Descriptive cohort of adult patients with portal hypertension at a tertiary care institution in Colombia

Introducción. La hipertensión portal (HTP) se define como una elevación anormal de la presión venosa en el sistema portal que lleva al desarrollo de vías colaterales para desviar el flujo sanguíneo de la zona. Dentro de su etiología están las relacionadas con la cirrosis hepática y otras causas denominadas no cirróticas. El objetivo de este estudio fue evaluar los principales hallazgos demográficos, clínicos y paraclínicos en un grupo de pacientes con HTP, y determinar el uso de ayudas invasivas y no invasivas, y su disponibilidad para el diagnóstico y seguimiento de los pacientes en los centros que no cuentan con laboratorio de hemodinamia hepática, reflejando la dinámica de múltiples escenarios en Colombia. Metodología. Se realizó un estudio descriptivo de corte transversal, retrospectivo, en pacientes atendidos en una institución de tercer nivel del sur de Colombia, entre enero del año 2015 y diciembre del año 2020. Resultados. Se obtuvo una muestra de 61 pacientes en donde la mayoría de casos correspondían a hombres en la séptima década de la vida, procedentes del área urbana. La principal causa de consulta fue el sangrado digestivo (39,3 %), asociado a la presencia de telangiectasias (arañas vasculares) en el 37,2 %, seguido de circulación colateral (31,3 %) e ictericia (19,7 %). En la ecografía abdominal (realizada en el 57,4 % de los pacientes) predominaron la cirrosis (68 %) y la presencia de esplenomegalia (14,2 %), y en lospacientes con Doppler portal (realizado en el 16,4 %) se encontró hígado cirrótico (80 %) y dilatación portal (40 %). Con respecto a los hallazgos en la esofagogastroduodenoscopia predominó la presencia de várices esofágicas y gastritis crónica. Conclusión. El principal motivo de consulta fue el sangrado digestivo, en tanto que la cirrosis fue el antecedente y el hallazgo imagenológico más frecuente, seguido de las várices esofágicas. Se encontró que el uso de paraclínicos, ecografía abdominal, ecografía con Doppler portal y esofagogastroduodenoscopia fueron los más utilizados en el contexto clínico de los pacientes con el diagnóstico de HTP.

Introduction. Portal hypertension (PHT) is defined as an abnormal elevation of venous pressure in the portal system that leads to the development of collateral pathways to divert blood flow from the area. Within its etiology are those related to liver cirrhosis and other so-called non cirrhotic causes. The aim of this study was to evaluate the main demographic, clinical and paraclinical findings in a group of patients with PHT, and to determine the use of invasive and non-invasive aids, and their availability for the diagnosis and follow-up of patients in centers that do not have a hepatic hemodynamics laboratory, reflecting the dynamics of multiple scenarios in Colombia. Methodology. A descriptive, retrospective, cross-sectional, retrospective study was conducted in patients attended in a third level institution in Southern Colombia, between January 2015 and December 2020. Results. A sample of 61 patients was obtained where the majority of cases corresponded to men in the seventh decade of life, from the urban area. The main cause of consultation was digestive bleeding (39.3%), associated with the presence of telangiectasias (spider veins) in 37.2%, followed by collateral circulation (31.3%) and jaundice (19.7%). In abdominal ultrasound (performed in 57.4% of the patients), cirrhosis (68%) and the presence of splenomegaly (14.2%) predominated, and in patients with portal Doppler (performed in 16.4%), cirrhotic liver (80%) and portal dilatation (40%) were found. With respect to the findings in the esophagogastroduodenoscopy, esophageal varices and chronic gastritis were predominant. Conclusion. The main reason for consultation was gastrointestinal bleeding, while cirrhosis was the most frequent history and imaging finding, followed by esophageal varices. It was found that the use of paraclinics, abdominal ultrasound, ultrasound with portal Doppler and esophagogastroduodenoscopy were the most used in the clinical context of patients diagnosed with PHT.

Assessing a cut-off point for the diagnosis of abnormal uterine bleeding using the Menstrual Bleeding Questionnaire (MBQ): a validation and cultural translation study with Brazilian women

ABSTRACT BACKGROUND: Abnormal uterine bleeding (AUB) is a common condition, and the Menstrual Bleeding Questionnaire (MBQ) is used for its assessment. OBJECTIVES: To translate, assess the cut-off point for diagnosis, and explore psychometric properties of the MBQ for use in Brazilian Portuguese. DESIGN AND SETTING: Prospective cohort study including 200 women (100 with and 100 without AUB) at a tertiary referral center. METHODS: MBQ translation involved a pilot-testing phase, instrument adjustment, data collection, and back-translation. Cut-off point was obtained using receiver operating curve analysis. Menstrual patterns, impact on quality of life due to AUB, internal consistency, test-retest, responsiveness, and discriminant validity were assessed. For construct validity, the Pictorial Blood Assessment Chart (PBAC) and World Health Organization Quality of Life - abbreviated version (WHOQOL-BREF) were applied. RESULTS: Women with AUB were older, had higher body mass indices, and had a worse quality of life during menstruation. Regarding the MBQ's psychometric variables, Cronbach's alpha coefficient was > 0.70 in all analyses, high intraclass correlation coefficient was found in both groups; no ceiling and floor effects were observed, and construct validity was demonstrated (correlation between MBQ score, PBAC score, and clinical menstrual cycle data). No difference between MBQ and PBAC scores were perceived after the test-retest. Significant differences were found between MBQ and PBAC scores before and after treatment. An MBQ score ≥ 24 was associated with a high probability of AUB; accuracy of 98%. CONCLUSION: The MBQ is a reliable questionnaire for Brazilian women. The cut-off ≥ 24 shows high accuracy to discriminate AUB.

Application of valve removal technique in improved endoscopic dacryocystorhinostomy / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the efficacy of valve removal technology in improved endoscopic dacryocystorhinostomy.METHODS: Prospective randomized controlled study. A total of 92 patients(98 eyes)with nasolacrimal duct obstruction who underwent endoscopic dacryocystorhinostomy in our hospital from November 2020 to September 2022 were selected as the study subjects and they were randomly divided into group A(traditional group)and group B(improved group). The nasal mucosal flap was preserved after incision of the nasal mucosa in group A, the lacrimal sac flap and nasal mucosal flap were trimmed to an appropriate shape after the incision of the lacrimal sac, and the lacrimal sac flap the nasal mucosal flap were matched up. Group B made a “□” shaped incision on the nasal mucosa to remove the complete square nasal mucosa tissue. After the lacrimal sac was incised, the lacrimal sac mucosa was preserved as much as possible, and then the residual nasal mucosa was trimmed to make the lacrimal sac flap close to but not in contact with the residual nasal mucosa. Furthermore, the intraoperative bleeding volume and surgical duration of two groups of patients were recorded, and follow up until 3 mo postoperative. Nasal endoscopy and lacrimal duct flushing examinations were performed at 1 and 3 mo postoperative, respectively. The proliferation of granulation tissue within 5 mm of the ostial postoperative and the therapeutic effect were observed.RESULTS: At 3 mo postoperatively, 6 patients(7 eyes)who were lost to follow-up were excluded. A total of 44 eyes were included in group A, and 47 eyes were included in group B. The bleeding volume [27.00(22.00, 41.00)mL] and the surgical duration [35.00(33.00, 42.00)min] in group B were significantly lower than those in the group A(P<0.001). At 1 mo postoperatively, granulation tissue hyperplasia was observed within 5 mm of the ostial in 12 eyes of group A. In group B, granulation tissue hyperplasia was observed within 5 mm of the ostial in 1 eye. At 3 mo postoperatively, there were 9 eyes in group A with ostial adhesions but incomplete closure, and 2 eyes with complete closure; group B had 1 eye with mild adhesions at the ostial site and no ostial closure. The postoperative complications in the group B were significantly less than those in the group A(P<0.05), and the therapeutic effect was better than that in the group A(P<0.05).CONCLUSION: The application of valve removal technology in improving endoscopic dacryocystorhinostomy not only significantly reduces intraoperative bleeding and surgical duration, but also effectively reduces postoperative complications and improves surgical efficacy.

Primary Anorectal Melanoma: Case Report and Review of a Rare Neoplasm

Primary anorectal melanoma is a rare malignant melanocytic neoplasm; its principal manifestation is rectal bleeding. It has an ominous prognosis with a five-year survival rate of 10%. The case of a 56-year-old woman with rectal bleeding and the sensation of a rectal mass is presented. A polypoid lesion, resected transanally, was documented in the distal rectum during the colonoscopy. The histological study confirmed a primary anorectal melanoma.

El melanoma anorrectal primario es una neoplasia melanocítica maligna poco frecuente, su principal manifestación es el sangrado rectal. Tiene un pronóstico ominoso con una tasa de sobrevida del 10% a 5 años. Se presenta el caso de una mujer de 56 años con rectorragia y sensación de masa rectal. Durante la colonoscopia se documentó una lesión polipoide en el recto distal, que se resecó por vía transanal. El estudio histológico confirmó la presencia de un melanoma anorrectal primario.

Hemorragia digestiva alta / Upper Gastrointestinal Bleeding

Introducción: La hemorragia digestiva alta tiene una elevada morbimortalidad. La endoscopía digestiva alta es el estudio de elección para su diagnóstico y tratamiento. Objetivo: Describir la conducta ante la hemorragia digestiva alta. Métodos: Para la revisión bibliográfica se consultaron artículos científicos indexados en idioma español e inglés, relacionados con la hemorragia digestiva, publicados en las bases de datos PubMed, SciELO, Medline y Cochrane, pertenecientes a autores dedicados al estudio de este tema. Desarrollo: La hemorragia digestiva alta se clasifica, según la etiología de origen, en variceal y no variceal. La mayoría de los pacientes con hemorragia digestiva alta el sangrado se autolimita. La causa más habitual es la úlcera péptica, pero en caso de sangrado masivo la etiología más frecuente es la variceal. El empleo precoz de la terlipresina en los pacientes con hemorragia digestiva alta variceal mejora el control del sangrado y disminuye la mortalidad. Se debe hacer uso de escalas validadas de estratificación del riesgo: escala de riesgo de Rockall (tiene como propósito principal predecir la mortalidad y riesgo de resangrado del paciente) y la escala de Glasgow-Blatchford). Conclusiones: Sospechar la presencia de hemorragia digestiva alta, estratificar su riesgo e instaurar el manejo inicial y apropiado constituye una prioridad para el médico de urgencia(AU)

Introduction: Upper gastrointestinal bleeding presents high morbidity and mortality. Upper gastrointestinal endoscopy is the study of choice for its diagnosis and treatment. Objective: To describe the management of upper gastrointestinal bleeding. Methods: For the bibliographic review, the consultation was carried out of scientific articles indexed in Spanish and English, related to gastrointestinal bleeding, published in the databases PubMed, SciELO, Medline and Cochrane, belonging to authors dedicated to the study of this subject. Development: Upper gastrointestinal bleeding is classified, according to the etiology of origin, into variceal and nonvariceal. In most patients with upper gastrointestinal bleeding the bleeding as such is self-limiting. The most common cause is peptic ulcer; however, in the case of massive bleeding, the most frequent etiology is variceal. Early use of terlipressin in patients with variceal upper gastrointestinal bleeding improves bleeding control and decreases mortality. Validated risk stratification scales should be used: Rockall risk scale (its main purpose is to predict patient mortality and risk of bleeding recurrence) and the Glasgow-Blatchford scale. Conclusions: Suspecting the presence of upper gastrointestinal bleeding, stratifying its risk, as well as instituting initial and appropriate management, are a priority for the emergency physician(AU)

Ligadura de la arteria lingual: estrategia para hemorragias por lesión de la arteria en la base de la lengua: informe de dos casos / Lingual Artery Ligation: Strategy for Bleeding from Artery Injury at the Base of the Tongue: Report of Two Cases

La hemorragia producida por lesión de la arteria lingual en la base de la lengua por cirugías o por tumores es infrecuente. La mayor frecuencia en la indicación de abordajes transorales para tratar diferentes patologías que afectan la orofaringe requiere que el equipo quirúrgico tenga experiencia en el manejo de esta complicación. La ligadura de la arteria lingual en el cuello es una técnica quirúrgica muy eficaz para solucionar la hemorragia, pero es importante conocer las posibles variantes anatómicas que puede tener la arteria en su trayecto cervical. Debido a su baja incidencia se propone como objetivo describir dos casos clínicos de pacientes que tuvieron hemorragias graves por lesión de la arteria lingual en la base de la lengua, producidas por daño quirúrgico y por erosión por tumor. [AU]

The bleeding caused by injury to the lingual artery at the base of the tongue due to surgery or tumors is infrequent. The increased frequency in the indication of transoral approaches to treat different pathologies affecting the oropharynx requires the surgical team to have experience in managing this complication. Ligation of the lingual artery in the neck is a very effective surgical technique to solve the bleeding; however, it is essential to be aware of the possible anatomical variants the artery may have in its cervical trajectory. Due to its low incidence, we propose to describe two clinical cases of patients who had severe bleeding due to a lesion of the lingual artery at the base of the tongue, produced by surgical damage and erosion due to a tumor.

Manejo das irregularidades menstruais secundárias ao uso de contraceptivos ­ análise das recomendações atuais / Management of menstrual irregularities secondary to contraceptive use ­ analysis of current recommendations

As irregularidades menstruais representam uma série de desordens na quantida- de, duração, frequência ou regularidade do sangramento uterino. Entre suas cau- sas destaca-se o sangramento secundário ao uso de anticoncepcionais, uma razão frequente de descontinuidade dos contraceptivos, podendo aumentar as taxas de gestações não planejadas. Boa parte dos contraceptivos pode levar a mudanças no padrão de sangramento uterino, e a abordagem inicial do sangramentos irregula- res inclui a avaliação de outras possíveis causas, o reforço do uso correto da medi- cação, a tranquilização da paciente quanto à benignidade do quadro e à tendência a melhora com a continuidade do uso. Os anti-inflamatórios podem ser usados como estratégia inicial, e, não havendo resposta satisfatória, há alternativas espe- cíficas para cada método. Este trabalho visa identificar as recomendações atuais sobre o manejo do sangramento anormal decorrente de contraceptivos, por meio de revisão narrativa de estudos publicados sobre o tema nos últimos vinte anos.

Abnormal uterine bleeding represents a series of disorders in the amount, du- ration, frequency and or regularity of uterine bleeding. Among its causes, uterine bleeding secondary to the use of contraceptives stands out as a frequent reason for contraceptive discontinuity, which could lead to unplanned pregnancies. Most contraceptives can cause changes in the pattern of uterine bleeding, and the ini- tial approach of the abnormal bleeding includes assessing other possible cau- ses, reinforcing the correct use of medication, and reassuring the patient about the benignity of the condition and the tendency to improve with the continuity of the treatment. Anti-inflammatory drugs can be used as an initial strategy, and, if there is no satisfactory answer, there are specific alternatives for each contracep- tive method. This work aims to identify them current recommendations on the management of abnormal bleeding resulting from contraceptives use, through a narrative review of studies published on the subject in the last twenty years.

Serie de casos de sangrado intraluminal postoperatorio en colectomía izquierda / Case series of postoperative intraluminal bleeding in left colectomy

Introducción: El sangrado digestivo intraluminal postoperatorio es una entidad poco frecuente y su manifestación clínica no difiere de la hemorragia digestiva baja de otra etiología. A pesar de que su presentación más habitual es la hematoquecia autolimitada en la primera deposición, en un discreto porcentaje puede requerir transfusiones, tratamiento endoscópico, hemodinámico, o incluso cirugía. Objetivo: Analizar los pacientes con sangrado digestivo intraluminal postoperatorio tratados en un centro de alta complejidad y realizar una revisión bibliográfica del tema. Diseño: Estudio retrospectivo, descriptivo. Material y métodos: Pacientes con sangrado anastomótico durante el post operatorio inmediato de una colectomía izquierda, operados en el Servicio de Cirugía General y Coloproctología desde enero del 2017 a diciembre del 2021. Las variables estudiadas fueron edad, sexo, anticoagulación y su causa, descenso de hemoglobina, cirugía realizada y su indicación, vía de abordaje, configuración de la anastomosis, electividad de la cirugía, complicaciones, días de internación y manejo terapéutico. Resultados: Se incluyeron 4 pacientes con una edad media de 72 (rango 54-87) años y una distribución por sexo de 1:1. En todos la colectomía izquierda fue programada y en 3 el abordaje fue laparoscópico. La anastomosis fue termino-terminal con sutura mecánica circular. Todos los pacientes presentaron sangrado en las primeras 24 horas postoperatorias. El tratamiento fue decidido de acuerdo a la condición hemodinámica: en los 2 pacientes con estabilidad hemodinámica fue suficiente el tratamiento conservador con reanimación y transfusiones. Los otros 2 que presentaron inestabilidad hemodinámica requirieron manejo intervencionista con endoscopía rígida, videocolonoscopía y cirugía. Conclusión: El sangrado intraluminal es una complicación poco frecuente de la anastomosis colorrectal que requiere manejo intervencionista solo en los pacientes que presentan inestabilidad hemodinámica. (AU)

Introduction: Postoperative intraluminal gastrointestinal bleeding is a rare entity and its clinical manifestation does not differ from lower gastro-intestinal bleeding of another etiology. Despite the fact that its most common presentation is self-limited hematochezia at the first stool, in a small percentage it may require transfusions, endoscopic or hemodynamic management, or even surgery. Aim: To analyze the patients with postoperative intraluminal gastrointestinal bleeding treated in a tertiary center and to carry out a bibliographic review of the subject. Design: Retrospective descriptive study. Material and methods: Patients with immediate postoperative anastomotic bleeding from a left colectomy, operated on at the General Surgery and Coloproctology Service from January 2017 to December 2021 were included. The variables recorded were age, sex, anticoagulation and its cause, decrease in hemoglobin, procedure performed and its indication, surgical approach, type of anastomosis, electiveness of surgery, complications, hospital stay and management. Results: Four patients with a mean age of 72 (range 54-87) years and a 1:1 gender distribution were included. All procedures were elective and 3 laparoscopic. All anastomoses were performed end-to-end with a circular stapler. All patients presented bleeding in the first 24 postoperative hours. The treatment was decided according to the hemodynamic condition; patients with hemodynamic stability (2) received medical treatment while those with hemodynamic instability (2) required interventional management with rigid endoscopy, colonoscopy and surgery. Conclusion: Intraluminal bleeding is a rare complication of colorectal anastomosis that requires interventional management only in patients with hemodynamic instability. (AU)

Prolapso rectal completo / Complete Rectal Prolapse

Introducción: El prolapso rectal completo es la invaginación de las capas del recto a través del canal anal y su protrusión fuera de este. Su incidencia es de 2,5 por 100 000 habitantes con predominio en mujeres de edad avanzada. Es una afección de curso crónico y benigno, cuya presentación clínica y endoscópica es tan variable que puede confundirse con otras entidades como con el cáncer colorrectal. Objetivo: Presentar el caso de una paciente femenina, operada de prolapso rectal completo en la provincia de Cienfuegos. Presentación de caso: Se presenta una paciente femenina de 76 años de edad, blanca, de procedencia rural que acude a la consulta y refiere que lleva 12 días sin defecar. Además, presenta dolor, sangramiento rectal no activo y una masa que protruía a través de la región anal sugestiva al examen físico de un prolapso rectal completo. El tacto rectal confirma el diagnóstico. Se realiza reducción quirúrgica del prolapso por técnica de Delorme. Actualmente lleva 6 meses de operada con evolución favorable. Por lo poco frecuente de esta entidad se considera de interés científico su publicación. Conclusión: Esta entidad es poco común en el entorno médico, el gran cambio que causa en el nivel de vida de aquellos que la portan y sus complicaciones hace que requiera un tratamiento rápido y oportuno(AU)

Introduction: Complete rectal prolapse is the invagination of the rectal layers through the anal canal and its protrusion out of it. Its incidence is 2.5 per 100,000 inhabitants, predominantly in elderly women. It is a chronic and benign condition, whose clinical and endoscopic presentation is so variable that it can be confused with other entities, such as colorectal cancer. Objective: To present the case of a female patient who underwent surgery for complete rectal prolapse in the province of Cienfuegos. Case presentation: A 76-year-old female patient, white, from a rural area, came to the clinic and reported that she had not defecated for 12 days. In addition, she presents pain, nonactive rectal bleeding and a mass protruding through the anal region suggestive, on physical examination, of a complete rectal prolapse. Digital rectal examination confirmed the diagnosis. Surgical reduction of the prolapse was performed using the Delorme technique. She has undergone surgery for 6 months now, with favorable evolution. Due to the rarity of this entity, its publication is considered as scientifically interesting. Conclusion: This entity is uncommon in the medical environment. The great change that it causes in the living standards of those who carry it and its complications make it require a quick and timely treatment(AU)

Predictors of Bleeding after Percutaneous Coronary Intervention

Background: Acute coronary syndrome patient outcomes have been improved using early invasive techniques. The aim of this study was to investigate the incidence, location, and severity of bleeding in PCI-treated cases to identify patient risk profiles and increased bleeding occurrences. Methods: This prospective observational study evaluated percutaneous coronary angiography in 80 patients with hypertension and diabetes mellitus who planned to undergo primary or elective PCI. The cases were separated into 2 groups; those who reported bleeding (n=11) and those who did not (n=69). All patients underwent physical examination, laboratory evaluation, 12-lead electrocardiography, and PCI. Results: In univariate regression analysis, age (OR: 1.09, 95% CI: 1.009 – 1.192), female gender (OR: 4.32, 95% CI: 1.157 – 16.131), history of peripheral arterial disease (OR: 7.31, 95% CI: 1.585 – 33.742), and femoral site of vascular access (OR: 9.6, 95% CI: 2.263 – 40.721) were independent predictors of major bleeding after PCI. In multivariate regression analysis, age (OR: 1.12, 95% CI:1.014 – 1.269), female gender (OR: 13.75, 95% CI: 1.983 – 161.2), history of peripheral arterial disease (OR: 43.38, 95% CI: 3.754 - 1042) and femoral site of vascular access (OR: 13.29, 95% CI: 2.233 – 128.5) were independent predictors of major bleeding after PCI. Conclusions: Patients who reported bleeding after PCI had a significantly higher age, prevalence of female sex, serum creatinine, and transfemoral intervention before and after intervention compared to patients who did not report bleeding, while haemoglobin and transradial intervention before and after intervention were significantly lower in the bleeding cases than in the non-bleeding cases.

A Rare Complication of Gastrointestinal Bleeding: Jejunal Diverticulosis. A Case Report

Introduction: Small intestine diverticula are a rare condition with an incidence of 0.6% to 2%. Their location at the level of the jejunum is a rare alteration, and their diagnosis is often delayed due to low clinical suspicion. The clinical manifestation of this pathology is related to the development of complications -15% to 30% of patients, with approximately 10% requiring surgical intervention. Clinical case: We present a case of a middle-aged adult patient who experienced a complication due to a bleeding jejunal diverticulum. The patient underwent surgical management, which resulted in a satisfactory outcome. Objective: This article aims to describe jejunal diverticulosis, a rare condition that can have a significant impact on affected individuals. Emphasizing its clinical suspicion as a differential diagnosis for gastrointestinal bleeding is crucial. Additionally, we discuss diagnostic methods and highlight various therapeutic options, including surgical management.

Introducción: los divertículos del intestino delgado presentan una incidencia del 0,6% al 2%, su localización a nivel del yeyuno es una alteración poco frecuente y, dada su baja sospecha clínica, se retrasa el diagnóstico oportuno. La manifestación clínica de esta patología se encuentra relacionada con el desarrollo de complicaciones, las cuales ocurren entre el 15% y el 30% de los pacientes, y el 10% de estos pacientes requiere manejo quirúrgico. Caso clínico: un paciente adulto medio cursó con una complicación secundaria a la presencia de un divertículo del yeyuno sangrante, al cual se le dio un manejo quirúrgico con un resultado satisfactorio. Objetivo: este artículo tiene como objetivo describir la diverticulosis yeyunal que, aunque poco frecuente, puede generar un compromiso importante en quien la padece, lo que prioriza su sospecha clínica como diagnóstico diferencial causante de hemorragia gastrointestinal, así como dilucidar métodos diagnósticos y estar al tanto de las diferentes opciones terapéuticas que existen, incluido el manejo quirúrgico.

Massive Gastrointestinal Bleeding Caused by Multiple Small Intestinal Diverticula: A Case Study

We report the case of a 71-year-old woman with multiple comorbidities who was admitted to the hospital due to hematochezia, without hemodynamic instability. Initial investigations, including colonoscopy and upper endoscopy, did not reveal the cause of bleeding. However, the patient experienced increased bleeding, anemia, and hemodynamic instability during her hospital stay. Subsequent selective angiography did not show any signs of active bleeding. In light of the persistent shock, surgical intervention was performed, which revealed blood originating from multiple diverticula in the jejunum.

Se presenta el caso de una mujer de 71 años con múltiples comorbilidades que ingresó por hematoquecia sin inestabilidad hemodinámica. Se inició el estudio con una colonoscopia sin evidenciar la causa; durante la estancia hospitalaria presentó un aumento del sangrado, anemización e inestabilidad hemodinámica, por lo que se realizó una endoscopia digestiva alta sin hallazgos; posteriormente, se realizó una angiografía selectiva sin evidencia de sangrado activo. Ante el choque persistente se llevó a cirugía en la que se evidenció sangre proveniente del intestino delgado secundaria a la presencia de divertículos múltiples en el yeyuno.

Escala predictiva de los resultados adversos en la hemorragia digestiva alta no varicosa

Introducción: Existen varios sistemas de puntuación para predecir los resultados adversos en los pacientes con hemorragia digestiva alta no varicosa, pero no se han validado lo suficiente y cada uno pertenece a distintas poblaciones fuentes. Objetivo: Demostrar la utilidad de una escala propuesta para predecir las probabilidades de resangrado, de mortalidad y de necesidad de cirugía en los pacientes con hemorragia digestiva alta no varicosa. Métodos: Se realizó un estudio retrospectivo de una prueba diagnóstica en el hospital de Prenda, Luanda, Angola desde enero del 2021 hasta mayo del 2022. El universo estuvo formado por 93 pacientes atendidos durante ese período con el criterio de inclusión de tener el diagnóstico de hemorragia digestiva alta de origen no varicoso. Resultados: De un total de 93 pacientes se obtuvo como desenlace primario una recurrencia del sangrado de 18 pacientes para un 19,35 % del total, seguido con 12 fallecidos para un 12,90 % del total y cuatro fallecidos para un 4,40 % del total. Los valores predictivos de la escala de forma general fueron, al ser aplicada una sensibilidad de 0,91, la especificidad de un 0,92, el valor predictivo negativo de un 0,95 y el valor predictivo negativo de un 0,86. Conclusiones: La escala propuesta tiene una sensibilidad y especificidad adecuada para predecir, en los pacientes con hemorragia digestiva alta no varicosa, la probabilidad de resangrado, de mortalidad y la necesidad de cirugía.

Introduction: Several scoring systems exist to predict adverse outcomes in patients with nonvariceal upper gastrointestinal bleeding, but they have not been sufficiently validated and each pertains to different source populations. Objective: To demonstrate the usefulness of a proposed scoring scale to predict the probability of rebleeding, mortality, and need for surgery in patients with nonvariceal upper gastrointestinal bleeding. Methods: A retrospective study of a diagnostic test was performed at the hospital of Prenda, Luanda, Angola, from January 2021 to May 2022. The study universe consisted of 93 patients attended during that period, with the inclusion criterion of having a diagnosis of upper gastrointestinal bleeding of nonvariceal origin. Results: From a total of 93 patients, the primary outcome was a recurrence of bleeding in 18 patients, accounting for 19.35% of the total; followed by 12 deaths, representing 12.90% of the total, and four deaths, accounting for 4.40% of the total. After the scale was applied, the following general predictive values were obtained: sensitivity of 0.91, specificity of 0.92, negative predictive value of 0.95 and negative predictive value of 0.86. Conclusions: The proposed scale presents adequate sensitivity and specificity for predicting the probability of fatal rebleeding and the need for surgery in patients with nonvariceal upper gastrointestinal bleeding.

Fatores preditivos de morbidade associada à sangramento de varizes esofágicas em crianças com hipertensão porta / Predictive factors of morbidity associated with esophageal variceal bleeding in children with portal hypertension

ABSTRACT Background: Most data on the natural history of portal hypertension come from studies in adults. The morbidity rate of upper gastrointestinal bleeding (UGIB) in children with portal hypertension has not been systematically characterized. Objective: To describe the morbidity and mortality of UGIB in pediatric patients with portal hypertension and identify predictive factors for the occurrence of its main complications. Methods: This retrospective study included pediatric patients with cirrhotic portal hypertension or with extrahepatic portal vein obstruction (EHPVO). Mortality and UGIB complications within a period of up to 6 weeks of the bleeding were investigated. To determine the predictive factors of morbidity, a multivariate analysis was performed using logistic regression; all results were considered significant at P<0.05. Results: A total of 86 patients (51.2% with EHPVO and 48.8% with cirrhosis) had 174 bleeding events. Ascites was the most common complication (43.1% of all cases), being more prevalent in patients with cirrhosis (P<0.001). Cirrhosis was a predictor of the occurrence of any morbidity (OR 20.3). The need for blood transfusion was predictor of at least one complication (OR 5.8), ascites (OR 7.2) and infections (OR 3.8) in the general group and at least one complication (OR 11.3) and ascites (OR 5.8) in cirrhotic patients. The need for expansion was a predictor of any morbidity (OR 4.6) and infections (OR 3.9) in the general group, in addition to being predictor of infection in cirrhotic patients (OR 5.4). There were no deaths from UGIB in the six weeks post-bleeding. Conclusion: The study showed the relevance of morbidity after UGIB in pediatric patients with portal hypertension, especially in those with cirrhosis. The patients with hemodynamic instability requiring blood transfusion or expansion on admission are at increased risk of complications related to upper gastrointestinal bleeding and should be closely monitored.

RESUMO Contexto: A maioria dos dados sobre a história natural da hipertensão porta provém de estudos em adultos. A morbidade associada à hemorragia digestiva alta (HDA) em crianças com hipertensão porta ainda não foi sistematicamente estudada. Objetivo: Descrever a morbimortalidade da HDA em pacientes pediátricos com hipertensão porta e identificar fatores preditivos para a ocorrência de suas principais complicações. Métodos: Este estudo retrospectivo incluiu pacientes pediátricos com hipertensão porta cirrótica ou com obstrução extra-hepática da veia porta (OEHVP). A mortalidade e as complicações da HDA foram estudadas até seis semanas após o sangramento. Para determinar os fatores preditivos de morbidade, foi realizada análise multivariada por meio de regressão logística; todos os resultados foram considerados significativos com P<0,05. Resultados: Oitenta e seis pacientes (51,2% com OEHVP e 48,8% com cirrose) tiveram 174 eventos hemorrágicos. A ascite foi a complicação mais comum (43,1% de todos os casos), sendo mais prevalente em pacientes com cirrose (P<0,001). A cirrose foi preditor da ocorrência de pelo menos uma complicação (OR 20,3). A necessidade de transfusão sanguínea foi preditora de pelo menos uma complicação (OR 5,8), ascite (OR 7,2) e infecções (OR 3,8) no grupo geral e pelo menos uma complicação (OR 11,3) e ascite (OR 5,8) nos cirróticos. A necessidade de expansão foi preditor de qualquer morbidade (OR 4,6) e infecções (OR 3,9) no grupo geral, além de ser preditor de infecção em cirróticos (OR 5,4). Não houve óbitos por HDA nas 6 semanas pós-sangramento. Conclusão: O estudo mostrou a relevância da morbidade após HDA em pacientes pediátricos com hipertensão porta, principalmente naqueles com cirrose. Os pacientes com instabilidade hemodinâmica que necessitam de transfusão de sangue ou expansão na admissão têm risco aumentado de complicações relacionadas à hemorragia digestiva alta e devem ser monitorados de perto.

Complicaciones tromboembólicas y hemorrágicas en pacientes portadores de prótesis valvulares del corazón en un centro de tercer nivel. ¿Qué hemos aprendido? / Thromboembolic and hemorrhagic complications in patients with prosthetic heart valves at third level care center. What have we learned?

Resumen Antecedentes: El reemplazo valvular por prótesis mecánicas o biológicas implica riesgo de tromboembolismo y complicaciones hemorrágicas. Objetivo: Determinar las complicaciones relacionadas con la terapia de anticoagulación complementaria y la probabilidad de riesgo en pacientes portadores de prótesis valvulares del corazón. Métodos: Se estudiaron 163 pacientes entre 2002 y 2016, portadores de prótesis mecánicas y biológicas, quienes recibieron antagonistas de la vitamina K posterior al egreso hospitalario. La terapia de anticoagulación se categorizó en óptima y no óptima conforme a los valores de INR previos a las complicaciones. Fueron excluidos los pacientes con comorbilidades y otros factores de riesgo de trombosis y/o sangrado. Resultados: a 68.7 % de los pacientes se les colocó prótesis mecánica y a 31.3 %, biológica (p ≤ 0.001); 25.2 % presentó las complicaciones motivo de estudio (p ≤ 0.001), hemorrágicas en 48.8 %, tromboembólicas en 26.8 % y de ambos tipos en 24.4 % (riesgo relativo = 4.229); a 95.1 % de los pacientes con complicaciones se les colocó prótesis mecánica y a 4.9 %, biológica (p = 0.005); 49.7 % presentó INR no óptimo (p ≤ 0.001). Conclusiones: Ante riesgo alto de complicaciones tromboembólicas y hemorrágicas, la elección de las prótesis valvulares, la prevención y el seguimiento son prioridades, principalmente en quienes requieren terapia de anticoagulación.

Abstract Background: Heart valve replacement surgery with mechanical or biological prostheses entails a risk of thromboembolism and bleeding complications. Objective: To determine the complications related to complementary anticoagulation therapy and the probability of risk. Methods: One-hundred and sixty-three patients who underwent heart valve replacement between 2002 and 2016 with either mechanical or biological prostheses, and who received vitamin K antagonists after hospital discharge, were studied. Anticoagulation therapy was categorized into optimal and non-optimal according to INR values prior to the development of complications. Patients with comorbidities and other risk factors for thrombosis and/or bleeding were excluded. Results: In total, 68.7 % of patients received mechanical prostheses, and 31.3 %, biological prostheses (p ≤ 0.001); 25.2 % experienced the complications that motivated the study (p ≤ 0.001), which were hemorrhagic in 48.8 %, thromboembolic in 26.8 %, and of both types in 24.4 % (relative risk = 4.229). Among the patients with complications, 95.1 % received mechanical prostheses, and 4.9 %, biological (p = 0.005); non-optimal INR was identified in 49.7 % (p ≤ 0.001). Conclusions: Given the high risk of thromboembolic and hemorrhagic complications, valve prostheses must be carefully chosen, and care priorities should include prevention and follow-up, especially in those patients who require anticoagulation therapy.

Hemorragia digestiva baja: factores de riesgo de gravedad, necesidad de cirugía de urgencia y mortalidad hospitalaria / Lower gastrointestinal bleeding: risk factors of severity, need for emergency surgery and in-hospital Mortality

RESUMEN Antecedentes: Últimamente creció el interés en poder determinar, en etapas tempranas de las hemorragias digestivas bajas (HDB), aquellos factores de riesgo relacionados con la posibilidad de presentar resultados evolutivos adversos. Objectivo: Determinar los factores de riesgo asociados a sangrados graves, cirugía de urgencia y mortalidad hospitalaria. Material y métodos: Realizamos un estudio observacional y retrospectivo sobre 1.850 pacientes, atendidos en forma consecutiva entre enero de 1999 y diciembre de 2018 por HDB. Para evaluar el riesgo de gravedad analizamos trece variables en las primeras cuatro horas desde la admisión. Para determinar los factores relacionados con la cirugía de urgencia, agregamos la enfermedad diverticular y, para evaluar mortalidad, la cirugía de urgencia y el puntaje (score) preoperatorio de la Sociedad Americana de Anestesiología (ASA). Resultados: De los 1.850 casos, 194 fueron graves y 1656 leves/moderados. Resultaron estadísticamente significativos como factores de mayor gravedad: > 70 años, FC > 120 lat/min., TA < 90 mm Hg, oliguria, hematoquecia masiva, hematocrito < 30%, hemoglobina < 7 g/% y necesidad transfusional. Resultaron predictores significativos de cirugía de urgencia: > 70 años, anti-coagulación, hipotensión arterial, taquicardia, hemoglobina < 7 g/%, oliguria, transfusiones y hematoquecia masiva. Se construyó una fórmula pronóstica de requerimiento de cirugía (sensibilidad 94%, especificidad 74%, valor predictivo positivo 91% y valor predictivo negativo 81%). AUC: 0,89%. Fueron significativos para mortalidad: > 70 años, anticoagulados, hematoquecia masiva, transfusiones y cirugía urgente. De los dieciséis pacientes operados y fallecidos de la serie, quince presentaban un ASA ≥ IV. Conclusiones: Las variables utilizadas resultaron simples, fiables y estadísticamente significativas para predecir gravedad, cirugía de urgencia y mortalidad.

ABSTRACT Background: Background: There has been a growing interest in determining those risk factors associated with adverse outcomes in early stages of lower gastrointestinal bleeding (LGIB). Objective: The aim of our study was to analyze the risk factors associated with severe bleeding, emergency surgery and in-hospital mortality. Material and methods: We conducted an observational and retrospective study on 1850 patients consecutive managed between January 1999 and December 2018 for LGIB. We analyzed thirteen variables within the first four hours of hospitalization to evaluate risk severity. Diverticular disease was considered to determine factors associated with emergency surgery, and the preoperative American Society of Anesthesiologists (ASA) score was used to assess mortality and emergency surgery. Results: Out of 1850 cases, 194 were severe and 1656 were mild/moderate, Patients > 70 years, with HR > 120 beats/min, BP < 90 mm Hg, oliguria, massive hematochezia, hematocrit < 30%, hemoglobin < 7 g% and need for transfusions presented statistically significant associations with severe bleeding. Age > 70 years, anticoagulation, hypotension, tachycardia, hemoglobin < 7 g%, oliguria, need for transfusion and massive hematochezia were significant predictors of emergency surgery. A prognostic formula was constructed to predict the need for surgery (sensitivity 94%, specificity 74%, positive predictive value 91% and negative predictive value 81%). AUC-ROC: 0,89%. Age > 70 years, anticoagulation, massive hematochezia transfusions and emergency surgery were identified as predictors of mortality. Fifteen of the sixteen patients who underwent surgery and died had ASA ≥ grade 4. Conclusions: The variables analyzed are simple, reliable and statistically significant to estimate the risk of severe bleeding, need for emergency surgery and mortality.

Evaluation of Haemostatic Effects of Petroselinum crispum(Parsley) in Wistar Rats

Petroselinum crispum(parsley or garden parsley), besides its use as an edible vegetable, is used in the treatment of various ailments with documented evidence validating some of these medicinal uses. The present study evaluates the impact of oral administration of P. crispumon blood coagulation parameters. Fresh leaves of P. crispum were locally sourced, authenticated and extracted using ethanol to obtain an ethanolic extract of P. crispum (PCE). Twenty-five (25) male Wistar rats were used for the study and were randomly assigned to five (5) animals of five (5) rats each. Group I served as the control group and was given distilled water, whereas groups II, III, and IV were treated as experimental groups and administered PCE at 200, 400, and 800mg/kg via oral gavage, respectively. Group V also received 800mg/kg of PCE with the administration terminated on the 28thday to allow for a 14-day recovery period. Platelet count (PLT) and other platelet indices were determined using an automated Haematology analyzer. Bleeding time (BT), clotting time (CT), prothrombin time (PT), activated partial thromboplastin time (aPTT) and plasma fibrinogen (FIB) were assayed following standard laboratory protocols. The results of the study show that the mean PLT were significantly reduced in the experimental animals compared to the control (p<0.05) while BT, CT, PT, aPTT and FIB significantly increased compared to the control (p<0.05). Also, BT, CT, PT, and aPTT recovered towards the control values after the 14-day withdrawal period. The present study shows ethanolic leaf extract of P. crispumprolonged blood coagulation. The current evidence suggests that P. crispumcould be a candidate for further exploration as a natural plant-based antithrombotic agent.

Prevalence of tooth loss, bleeding on probing and malocclusion as oral disease indicators in Costa Rican male adolescents: a cross sectional study / Prevalencia de la pérdida de piezas dentales, del sangrado al sondeo y la maloclusión como indicadores de enfermedades orales en adolescentes varones costarricenses: un estudio transversal

The evidence to characterize oral health during adolescence in Costa Rica is limited. This lack of adequate research makes it difficult to develop appropriate health policies for this subgroup of the population. This is particularly important because adolescence is the period during which good health habits must take root in order to foster good physical and cognitive development. This study aims to determine the prevalence of tooth loss, bleeding on probing and malocclusion in Costa Rican male adolescents at the ''Colegio Técnico Profesional San Agustín'' (St. Augustine's Technical High School) located in the province of Cartago. Data was collected from 428 male adolescents aged 12-22 years in a cross-sectional study during 2019. Prevalence of tooth loss was calculated as the number of individuals having lost at least one tooth. The average number of teeth lost by individuals was also recorded. The bleeding on probing was an indicator used as a proxy parameter for monitoring periodontal health where the presence of bleeding on probing and calculus was also recorded. Malocclusion was measured using the Dental Aesthetic Index (DAI). The results showed that the prevalence of tooth loss, bleeding on probing and malocclusion was of 19%, 70.0% and 98%, respectively. It was also found that 81% of the participants had all their teeth, 11% had lost 1 tooth, 8% had lost more than one tooth of which 0.5% had lost more than 5 teeth. Considering a general classification of periodontal problems based on bleeding on probing and presence of calculus, the prevalence of periodontal problems increases to 92%. Regarding the DAI, the category identifying a very severe malocclusion was the most prevalent in the sample (88%). It is alarming the high prevalence of tooth loss, bleeding on probing, and malocclusions in a sample of Costa Rican male adolescents, compared to similar studies in other countries. The overarching conclusion of this study is that oral diseases represent an important health problem that urgently need proper public health action.

La evidencia para caracterizar la salud bucal durante la adolescencia en Costa Rica es limitada. Esta falta de investigación adecuada dificulta el desarrollo de políticas de salud convenientes para este subgrupo de la población. Esto es particularmente importante porque la adolescencia es el período durante el cual se deben arraigar buenos hábitos de salud para fomentar un buen desarrollo físico y cognitivo. Este estudio tiene como objetivo determinar la prevalencia de pérdida de piezas dentales, sangrado al sondeo y maloclusión en adolescentes varones costarricenses del Colegio Técnico Profesional San Agustín ubicado en la provincia de Cartago. Se recopilaron datos de 428 adolescentes varones de 12 a 22 años en un estudio transversal durante 2019. La prevalencia de pérdida de piezas dentales se calculó como el número de individuos que habían perdido al menos una pieza dental. También se registró el número promedio de dientes perdidos por individuos. El sangrado al sondeo fue un indicador utilizado como parámetro para el seguimiento de la salud periodontal donde también se registró la presencia de sangrado al sondeo y cálculo dental. La maloclusión se midió utilizando el Índice Estético Dental (DAI, por sus siglas en inglés). Los resultados mostraron que la prevalencia de pérdida de piezas dentales, sangrado al sondeo y maloclusión fue del 19%, 70,0% y 98%, respectivamente. También se encontró que el 81% de los participantes tenían todos sus dientes, el 11% había perdido 1 pieza dental, el 8% había perdido más de una pieza dental, de los cuales el 0,5% había perdido más de 5 piezas dentales. Considerando una clasificación general de problemas periodontales basada en sangrado al sondeo y presencia de cálculo, la prevalencia de problemas periodontales aumenta al 92%. En cuanto al DAI, la categoría que identifica una maloclusión muy severa fue la más prevalente en la muestra (88%). Es alarmante la alta prevalencia de pérdida de piezas dentales, sangrado al sondeo y maloclusiones en una muestra de adolescentes varones costarricenses, en comparación con estudios similares en otros países. La conclusión general de este estudio es que las enfermedades bucodentales representan un importante problema de salud que necesita urgentemente una acción adecuada de salud pública.
