ABSTRACT

Introduction: The cecum is the first part of the large bowel. Cecectomy is a sufficient treatment for some patients, avoiding overtreatment by ileocolic resection. Purpose:The goal of this study was to review a surgeon's experience with laparoscopic cecectomy and provide a technical video demonstration of this uncommon operation. Methods: A retrospective chart review was conducted of all consecutive patients treated with laparoscopic cecectomy over a 16-year period. All operations were performed using a 3-trocar technique. The cecum was transected with 1 to 2 firings of a 60 millimeters linear stapler, preserving the ileocecal valve and ascending colon. Results: 19 patients were identified including 12 females (63.2%). Median age was 42 years (range 16-84). Indication for surgery included appendiceal pathology in 12 patients (63.2%) and cecal abnormality in 7 (38.9%). There was no conversion to open surgery. Median intraoperative blood loss was 25 ml (range 0-150 ml) and no patient received a blood transfusion. No intraoperative or postoperative complication was noted. The median length stay was 1 day (range 0-6). Readmission rate was 0%. Final appendiceal histopathology revealed acute/chronic appendicitis in 5 patients, mucinous cystadenoma in 4 patients. Cecal histopathology revealed adenoma in 4 patients. Median follow-up was 16 months (range 4-53). Conclusions: Laparoscopic cecectomy is a sufficient treatment for some patients with benign conditions of the appendix and cecum. It carries minimal morbidity. It should be considered as an alternative to segmental bowel resection in a select group of patients. (AU)

ABSTRACT

La invaginación intestinal sucede cuando un segmento del intestino se introduce en otro. La presentación apendicular es menos común, afectando principalmente a lactantes. Frecuentemente, se comprueba durante el intraoperatorio. El tratamiento es la desinvaginación, seguido de la exéresis del apéndice. De no lograrse, se prefiere la resección amplia o una hemicolectomía derecha. Se presenta en caso de una niña de 4 años que acudió por dolor abdominal, hiporexia, vómitos y sensación de alza térmica; la ecografía mostró conglomeración de asas intestinales e imagen redondeada. En cirugía se encontró invaginación apendicular que compromete el ciego, se resecó la masa hasta el inicio del colon ascendente. Se realizó una ileostomía sin fístula mucosa; el estudio anatomo-patológico informó necrosis del apéndice cecal. Tres meses después se restituyó el tránsito intestinal. La Intususcepción apendicular tiene síntomas inespecíficos. En Perú, puede llegar a ser mortal. Una historia clínica detallada con evaluación minuciosa ofrece un acertado diagnóstico y un tratamiento oportuno.


SUMMARY Intestinal invagination occurs when an intestinal segment is introduced into another segment. The appendicular presentation is less common and affects predominantly infants. The diagnosis is corroborated during the surgical intervention which consists of de-invagination followed by surgical removal of the appendix, if the latter is not possible then a wide resection or right hemicolectomy is indicated. We present the case of a 4-year-old girl who attended with a history of abdominal pain, anorexia, vomiting and fever; an abdominal ultrasound showed intestinal agglomeration and a rounded mass. The surgical findings included appendicular invagination that affected the cecum, the lesion was resected until the ascending colon. An ileostomy was performed, the anatomopathological findings indicated necrosis of the appendix. Three months later the normal intestinal transit was restored. Appendicular intussusception has non-specific symptoms and could be mortal in Peru. A detailed clinical history may help in diagnosing and offering proper treatment.

ABSTRACT

La Apendicitis Aguda se manifiesta cuando existe inflamación del apéndice cecal, representando una de las más notables causas de abdomen agudo con pronóstico quirúrgico en el mundo. Existen sistemas de puntuaciones que se han generado para su comprobación, mediante técnicas no invasivas, de fácil aplicación y reproducción; destacando entre ellas las escalas de ALVARADO, RIPASA, AIR, entre otras. Objetivo: Comparar la sensibilidad y especificidad de las escalas AIR Vs. RIPASA para el diagnóstico de la Apendicitis Aguda en el Hospital General Nacional "Dr. Ángel Larralde", período enero 2020 ­ diciembre 2022. Materiales: Estudio observacional, descriptivo y evaluativo, prospectivo y de corte transversal. Muestra fue intencional no probabilística, cumpliendo con los criterios de inclusión. Para la recolección de datos, se empleó la observación directa como técnica y como instrumentos las escalas AIR y RIPASA. Resultados: Muestra conformada por 192 pacientes, sin predisposición de géneros. Sensibilidad, especificidad, valor predictivo positivo, valor predictivo negativo y exactitud diagnóstica AIR: 70%; 58,33%; 73,68%; 53,84%; 65,62%; RIPASA: 88,88%; 42,85%; 66,66%; 75%; 68,75%. Conclusiones: La exactitud diagnóstica para la escala de RIPASA fue ligeramente mayor que para AIR (68,75% vs. 65,62%), permitiendo afirmar que, en el grupo de estudio, resultó más conveniente la aplicación de la escala de RIPASA en pacientes sanos para el diagnóstico correcto de Apendicitis Aguda(AU)


Acute Appendicitis manifests when there is inflammation of the cecal appendix, representing one of the most notable causes of acute abdomen with surgical prognosis in the world. There are scoring systems that have been generated for verification, using non-invasive techniques that are easy to apply and reproduce; highlighting among them the scales of ALVARADO, RIPASA, AIR, among others.Objective : To compare the sensitivity and specificity of the AIR Vs. RIPASA scales for the diagnosis of Acute Appendicitis at the National General Hospital "Dr. Ángel Larralde", period January 2020 ­ December 2022. Materials: Observational, descriptive and evaluative, prospective and cross-sectional study. Sample was intentional, non-probabilistic, meeting the inclusion criteria. For data collection, direct observation was used as a technique and the AIR and RIPASA scales as instruments.Results : Sample made up of 192 patients, with no gender predisposition. Sensitivity, specificity, positive predictive value, negative predictive value, and AIR diagnostic accuracy: 70%; 58.33%; 73.68%; 53.84%; 65.62%; RIPASE: 88.88%; 42.85%; 66.66%; 75%; 68.75%.Conclusions : The diagnostic accuracy for the RIPASA scale was slightly higher than for AIR (68.75% vs. 65.62%), allowing us to affirm that, in the study group, the application of the RIPASA scale was more convenient in healthy patients for the correct diagnosis of Acute Appendicitis(AU)

ABSTRACT

Introducción. El apéndice cecal invertido, inversión apendicular o intususcepción apendicular, corresponde a una condición anatómica descrita en 1859. La primera operación de invaginación apendicular se realizó en 1890, y desde entonces se han descrito diferentes técnicas quirúrgicas y endoscópicas para el tratamiento de esta alteración. Casos clínicos. Se presentandos casos de pacientes a quienes se les indicó colonoscopia como parte de estudio de dolor abdominal y diarrea y se identificó una intususcepción apendicular completa y apendicitis y una inversión del muñón apendicular. Resultados. Mediante la colonoscopia se hizo el diagnóstico de apendicitis aguda en una de las pacientes, quien presentaba inversión apendicular completa tipo 5, que fue tratada con manejo farmacológico y seguimiento clínico. En la otra paciente hubo un hallazgo incidental de inversión del muñón apendicular tipo 3. Conclusiones. Durante la realización de estudios colonoscópicos, se debe tener en cuenta el diagnóstico de intususcepción apendicular o apéndice invertido, para evitar intervenciones erróneas, como polipectomías, que generen riesgo potencial en los pacientes.


Introduction. Inverted cecal appendix, appendicular inversion or appendicular intussusception, corresponds to an anatomical condition described in 1859. The first appendicular invagination operation was performed in 1890, and since then different surgical and endoscopic techniques have been described for its treatment. Clinical cases. We present two patients who underwent colonoscopy as part of the study of abdominal pain and diarrhea and in whom were identified a complete appendicular intussusception and appendicitis, and an inversion of the appendicular stump. Results. Through colonoscopy, the diagnosis of acute appendicitis was made in one of the patients, who presented type 5 complete appendicular inversion, which was treated with pharmacological management and clinical follow-up. In the other patient, the incidental finding of inversion of the appendicular stump type 3 was made. Conclusions. During colonoscopy, the diagnosis of appendicular intussusception or inverted appendix must be taken into account to avoid erroneous interventions such as polypectomies that generate potential risk in patients.

ABSTRACT

Resumen Objetivo: Reportar el caso de una paciente con intususcepción apendicular (IA), condición infrecuente, secundario a foco de endometriosis, patología que en los últimos años ha presentado un aumento en su incidencia. Material y Método: Historia clínica, imágenes preoperatorias e intraoperatorias obtenidas de la ficha clínica. Resultados: Mujer de 35 años con dolor abdominal crónico de 4 meses de evolución. Se realiza estudio colonoscópico evidenciando lesión de 15 x 8 mm en ostium apendicular intususceptada al lumen cecal, y enteroclisis por tomografía axial computarizada (TC) que confirma IA. Se realiza una resección ileocecal laparoscópica demostrando la invaginación del apéndice con biopsia que muestra un foco de endometrioma. Discusión: La IA es una condición infrecuente con una incidencia cercana al 0,01% en la población general. Las patologías benignas son la principal causa (77%), siendo la endometriosis la causa más frecuente. Conclusión: La IA por endometriosis es anecdótica, con sintomatología poco específica. Los estudios disponibles pueden orientar adecuadamente la presencia de IA, sin embargo, en algunas ocasiones puede confundirse con patologías neoplásicas, donde cobra importancia la cirugía para dilucidar la etiología.


Objective: To report the case of a patient with appendicular intussusception (AI), an infrequent condition secondary to a focus of endometriosis, a pathology that has increased incidence in recent years. Material and Method: Clinical case, history and images obtained from the clinical file and intraoperative records with the consent of the patient. Results: A 35-year-old woman with abdominal pain. Colonoscopy study showing a 15 × 8 mm lesion in the appendicular ostium intussuscepted to the cecal lumen, and a computerized tomography (CT) enteroclysis confirming AI. A laparoscopic ileocecal resection is performed, demonstrating invagination of the appendix secondary to an endometrioma focus. Discussion: AI is a rare condition, with an incidence close to 0.01% in the general population. Benign pathologies are the main cause (77%), endometriosis being the most frequent cause. Conclusion: AI due to endometriosis is anecdotal, with unspecific symptoms. The available studies can adequately guide the presence of AI, however, on some occasions it can be confused with neoplastic pathologies, where surgery is important to elucidate the etiology.

ABSTRACT

Introducción. El dolor abdominal agudo es una causa frecuente de consulta en los servicios de urgencias. Su incidencia es alrededor del 5%, de los cuales el 10%- 25% de los pacientes requieren tratamiento quirúrgico. Las neoplasias apendiculares primarias son infrecuentes, actualmente representan 1% de las neoplasias malignas de origen gastrointestinal. Existe un predominio en mujeres y se debe sospechar en pacientes con factores de riesgo. El objetivo es entender la importancia del diagnóstico oportuno en el abordaje del paciente con dolor abdominal agudo. Presentación del caso. Mujer con cuadro clínico de 5 días de dolor abdominal, con hallazgo en tomografía de abdomen de marcada dilatación quística del apéndice cecal con calcificaciones lineales y nodulares en la pared y su interior. Intraoperariamente, se realizó hemicolectomía derecha con resultado histológico de neoplasia mucinosa del apéndice (adenoma serrado) con pérdida de la muscularis mucosae, catalogándolo como adenocarcinoma de bajo grado. Discusión. Los tumores apendiculares representan el 1% de las neoplasias malignas de origen gastrointestinal, son un hallazgo incidental (0.7-1.4%) en los procedimientos de apendicectomía. El diagnóstico es histopatológico y el pronóstico se relaciona con la clasificación. Es importante conocer, identificar y sospechar esta patología dada su infrecuencia, con lo cual se puede mejorar el pronóstico en los pacientes. Conclusión. Los tumores apendiculares son infrecuentes, los cuales deben ser incluidos en el grupo de patologías causantes de dolor abdominal agudo.


Introduction. Acute abdominal pain is a frequent cause of consultation to emergency services. Its incidence is about 5%, of which 10%-25% of patients require surgical treatment. Primary appendiceal neoplasms are infrequent. They currently represent 1% of malignant neoplasms of gastrointestinal origin. They are predominant in women and must be suspected in patients with risk factors. The objective is to understand the importance of timely diagnosis in approaching patients with acute abdominal pain. Case report. A woman with clinical condition of 5 days of abdominal pain. Marked cystic dilation of the cecal appendix with linear and nodular calcifications on its wall and interior found in a tomography of the abdomen. Intraoperatively, a right hemicolectomy was performed with a histological result of mucinous neoplasm of the appendix (serrated adenoma) with loss of the muscularis mucosae, classifying it as a low grade adenocarcinoma. Discussion. Appendiceal tumors represent 1% of malignant neoplasms of gastrointestinal origin, with an incidental finding (0.7-1.4%) in appendectomy procedures. The diagnosis is histopathological, and prognosis is related to its classification. It is important to know, identify and suspect this pathology due to its infrequency, which can improve the patient's prognosis. Conclusion. Appendiceal tumors are infrequent and should be included in the group of pathologies that cause acute abdominal pain.

Sua incidência é em torno de 5%, dos quais entre 10% e 25% dos pacientes necessitam de tratamento cirúrgico. As neoplasias primárias de apêndice são raras, representando atualmente 1% das neoplasias malignas de origem gastrointestinal. Há predominância em mulheres e deve-se suspeitar em pacientes com fatores de risco. O objetivo é compreender a importância do diagnóstico oportuno na abordagem de pacientes com dor abdominal aguda. Relato de caso. Mulher com quadro clínico de dor abdominal por 5 dias, com achado tomográfico de abdome de dilatação cística acentuada do apêndice cecal com calcificações lineares e nodulares na parede e seu interior. No intraoperatório foi realizada hemicolectomia direita com resultado histológico de neoplasia mucinosa de apêndice (adenoma serrilhado) com perda da muscularis mucosae, classificando-a como adenocarcinoma de baixo grau. Discussão. Os tumores apendiculares representam 1% das neoplasias malignas de origem gastrointestinal, sendo um achado incidental (0.7-1.4%) em procedimentos de apendicectomia. O diagnóstico é histopatológico e o prognóstico está relacionado à classificação. É importante conhecer, identificar e suspeitar desta patologia dada a sua infrequência, o que pode melhorar o prognóstico dos pacientes. Conclusão. Os tumores apendiculares são pouco frequentes e devem ser incluídos no grupo de patologias que causam dor abdominal aguda.

ABSTRACT

@#A 51-year-old gravida 5 para 5 (5005) presented with an increasing abdominal girth and a palpable abdominal mass. She was initially diagnosed with ovarian new growth and underwent exploratory laparotomy. Intraoperatively, the uterus, Fallopian tubes, and ovaries were grossly normal and a large mass was seen attached to the cecum where the appendix should be referral to surgery service was done. Right hemicolectomy and ileostomy were performed. The histopathology report was “suggestive of a Müllerian adenosarcoma (MAS) involving the appendix and cecum.” Microscopic examination showed evidence of endometriosis with no evidence of sarcomatous overgrowth, features that are favorable prognostic factors associated with higher disease-free survival. Postoperatively, the plan of management was hormonal therapy. Extragenital MAS is rare. This case is the fourth case to be reported in the literature to arise from the colon. Although there is still no standard of treatment, accurate diagnosis is imperative for appropriate management.

ABSTRACT

INTRODUCTION@#This study aimed to investigate the ultrasonographic features of paediatric acute appendicitis and incorporate them into a scoring algorithm that will quantify the risk of complications and the strength of recommendation for surgical intervention.@*METHODS@#179 patients with suspected appendicitis who had undergone ultrasonographic examination were included in this study. Based on their medical evaluation and post-surgical histopathological results, patients were categorised into confirmed appendicitis (n = 101) and non-appendicitis (n = 78) groups.@*RESULTS@#In the appendicitis group, the appendix was visualised in 66 (65.3%) patients. In cases where the appendix was not visualised, we looked out for secondary inflammatory signs, which were present in 32 (31.7%) patients. Using stepwise logistic regression, Blumberg's sign, free fluid or collection, hyperaemia, non-compressible appendix and an appendix diameter > 7 mm were found to be significant predictive factors for appendicitis. A new scoring system called POPs was developed, combining inflammatory predictors and ultrasonography findings, with an area under the receiver operating characteristic curve of 0.958 (95% confidence interval 0.929-0.986).@*CONCLUSION@#The newly developed POPs-based diagnosis scheme proved a promising alternative to existing scoring systems such as the Alvarado score. Although further calibration would be beneficial, the proposed scoring scheme is simple and easy to understand, memorise and apply in the emergency room.

ABSTRACT

OBJECTIVES@#To study the clinical efficacy of ultrasound-guided endoscopic retrograde appendicitis therapy in children with appendix-related chronic abdominal pain.@*METHODS@#A retrospective analysis was performed on the medical data of 30 children with the chief complaint of chronic abdominal pain who were admitted from August 2019 to May 2021. All the children were found to have inflammation of the appendix or intracavitary stool and fecalith by ultrasound and underwent ultrasound-guided endoscopic retrograde appendicitis therapy. The medical data for analysis included clinical manifestations, endoscopic findings, white blood cell count, neutrophil percentage, length of hospital stay, and cure rate.@*RESULTS@#Among the 30 children with chronic abdominal pain, there were 13 boys (43%) and 17 girls (57%), with a mean age of (9±3) years (range 3-15 years) at diagnosis. The median duration of the disease was 12 months, and the median length of hospital stay was 3 days. The children had a median white blood cell count of 6.7×109/L and a neutrophil percentage of 50%±13%. Fecalith and a large amount of feces were flushed out of the appendix cavity for 21 children (70%) during surgery. The follow-up rate was 97% (29/30), and the median follow-up time was 11 months (range 5-26 months). Of the 29 children, abdominal pain completely disappeared in 27 children (93%).@*CONCLUSIONS@#Ultrasound-guided endoscopic retrograde appendicitis therapy is effective in children with chronic abdominal pain caused by feces or fecalith in the appendix cavity.

ABSTRACT

Resumen La fístula uro-entérica es una comunicación patológica entre la vía urinaria y digestiva. El compromiso del apéndice es infrecuente y son pocos los casos de fístulas reno-apendiculares en la literatura. Se presenta el caso de un paciente con clínica de fiebre, dolor lumbar e hidronefrosis derecha severa secundaria a cálculo coraliforme en la tomografía de vías urinarias. Manejado inicialmente con antibióticos y nefrostomía bajo fluoroscopia, posteriormente suspendida por paso de contraste al intestino. Se realizó una tomografía contrastada que reportó fístula del riñón al intestino. Se llevó a nefrectomía y se encontró fistula hacía el apéndice, por lo cual se realizó apendicectomía concomitante con mejoría clínica evidente. La patología reportó pielonefritis xantogranulomatosa y apendicitis secundaria. La fístula reno-apendicular posee una clínica inespecífica, la tomografía contrastada es una herramienta diagnóstica y la mayoría se detectan como un hallazgo intraoperatorio. El tratamiento usualmente es quirúrgico, con nefrectomía y reparación del segmento intestinal. MÉD. UIS.2021;34(3): 79-84.


Abstract Uro-enteric fistula is a pathological communication between the urinary and digestive tract. Compromise of the appendix is infrequent and few cases of reno-appendicular fistulas have been described in the literature. The case of patient with symptoms of fever, low back pain and severe right hydronephrosis secondary to staghorn calculus on urinary tract tomography is presented. Initially managed with antibiotics and nephrostomy under fluoroscopy, subsequently suspended by passing contrast to the intestine. A contrasted tomography was performed which reported a fistula from the kidney to the intestine. A nephrectomy was carried out and a fistula was found to the appendix, for which a concomitant appendectomy was performed with evident clinical improvement. The pathology reported xanthogranulomatous pyelonephritis and secondary appendicitis. Reno-appendicular fistula has nonspecific symptoms, contrasted tomography is a diagnostic tool and most are detected as an intraoperative finding. Treatment is usually surgical, with nephrectomy and intestinal segment repair. MÉD.UIS.2021;34(3): 79-84.

ABSTRACT

RESUMEN La paracoccidioidomicosis es la micosis sistémica más prevalente en Latinoamérica. En niños la presentación clínica más frecuente es la forma juvenil o aguda/subaguda, que compromete principalmente los ganglios linfáticos y en menor proporción los órganos gastrointestinales. Presentamos el caso de un paciente de 10 años, sin comorbilidades, con dolor agudo en fosa iliaca derecha; además de historia de un mes de evolución de diarrea, fiebre, pérdida de peso e hipereosinofilia. Fue diagnosticado de apendicitis aguda secundaria a un cuadro de paracoccidioidomicosis sistémica, mediante histopatología del apéndice cecal y ganglios mesentéricos. Tuvo respuesta favorable al tratamiento con anfotericina B liposomal. A pesar de que la paracoccidioidomicosis sistémica con compromiso del apéndice cecal es infrecuente, debe considerarse como parte de los diagnósticos diferenciales en niños con linfadenomegalias generalizadas y procedentes de áreas endémicas.


ABSTRACT Paracoccidioidomycosis, the most prevalent systemic mycosis in Latin America. In children the most common clinical presentation is the juvenile or acute/subacute form, which mainly involves the lymph nodes and in a lesser proportion the gastrointestinal organs. We present the case of a 10-year-old patient, without comorbidities, who presented acute right iliac fossa pain; in addition to a history of 1 month of evolution of diarrhea, fever, weight loss, and hypereosinophilia. Was diagnosed of acute appendicitis due to systemic paracoccidioidomycosis, through histopathology of the cecal appendix and mesenteric lymph nodes. Although systemic paracoccidioidomycosis with involvement of the cecal appendix is ​​rare, it should be considered as part of the differential diagnoses in children and young adults with generalized lymphadenomegaly from endemic areas.

ABSTRACT

RESUMEN Objetivo. Determinar el título de anticuerpos frente al dominio de unión al receptor (RBD) de la proteína espiga (S) en personal de salud entre la 4.ª y 12.ª semana luego de haber recibido la vacuna BBIBP-CorV (Sinopharm). Materiales y métodos. Se incluyeron 168 trabajadores de salud de dos hospitales de la región, quienes cumplían el esquema completo con vacuna de Sinopharm, y se realizó la medición de anticuerpos en suero mediante la prueba Elecsys®Anti-SARS-CoV-2. Resultados. Todos los participantes desarrollaron anticuerpos frente al dominio RBD. El valor mínimo fue de 1,78 U/mL. En 70 (41,7%) participantes se encontraron niveles iguales o por encima de 250. La media geométrica fue de 82,6 (IC 95% 67,8-100,6). Las mujeres presentaron un mayor nivel de anticuerpos. El grupo de participantes en los que se midieron anticuerpos entre las semanas 4 y 7 posvacunación mostró niveles de anticuerpos significativamente mayores que los pacientes cuyas determinaciones fueron realizadas entre las 10 y 12 semanas posvacunación. Entre los pacientes con antecedente de COVID-19, los niveles de anticuerpos se encontraron en cifras iguales o por encima de 250 U/mL en el 88% de casos, en comparación con 6% entre aquellos sin antecedente de COVID-19, (p<0,001). Conclusión. Todos los participantes inmunizados con la vacuna BBIBP-CorV presentaron positividad a anticuerpos frente al RBD de la proteína S del SARS-CoV-2. Es necesario evaluar la correlación entre la magnitud de los títulos y la protección frente a COVID-19 y el tiempo de protección conferido por la vacuna.


ABSTRACT Objective. To determine the titer of antibodies against the receptor binding domain (RBD) of the spike protein (S) in health personnel between the 4th and 12th week after receiving the BBIBP-CorV vaccine (Sinopharm). Materials and methods. We included a total of 168 healthcare workers from two hospitals in the region, who complied with the complete Sinopharm vaccine schedule; serum antibodies were measured using the Elecsys® Anti-SARS-CoV-2 test. Results. All participants developed antibodies to the RBD domain. The lowest antibody titer level was 1.78 U/mL. Levels equal to or above 250 were found in 70 (41.7%) participants. The geometric mean was 82.6 (95% CI: 67.8-100.6). Women had higher antibody levels. Participants whose antibodies were measured between 4- and 7-weeks post-vaccination showed significantly higher antibody levels than patients whose antibody levels were measured between 10- and 12-weeks post-vaccination. Among patients with a history of COVID-19, antibody levels were found to be at or above 250 U/mL in 88% of cases, compared to 6% among those without a history of COVID-19, (p<0.001). Conclusion. All participants immunized with BBIBPCorV vaccine were positive for antibodies against the SARS-CoV-2 spike protein RBD. The correlation between the titer level and protection against COVID-19, as well as the length of the protection provided by the vaccine, needs to be evaluated.

ABSTRACT

Resumen Balantidium coli es el único miembro de la familia Balantidiidae capaz de producir infección en seres humanos. Presentamos un caso en un hombre de 43 años que ingresa para corrección quirúrgica de hernia ventral durante la cual se realizó apendicetomía profiláctica. En el estudio histopatológico se observó apéndice cecal con arquitectura conservada, sin la presencia de apendicitis ni periapendicitis. En la luz se reconocieron estructuras grandes (aproximado de 50 μm) redondas con citoplasma amplio con vacuolas grandes, cilias periféricas y núcleos densos, los cuales correspondieron a trofozoitos de Balantidium coli.


Abstract Balantidium coli is the only member of the Balantidiiae family capable of infecting human beings. We present one in a 43 years-old male admitted for a surgical co rrection of an incisional hernia with prophylactic appendicectomy. Histopathological findings reported the cecal appendix within normal architecture, appendicitis and peri-appendicitis free. At the lumen big, rounded shape structures (aprox. 50 mm) were visible with broad cytoplasm, big vacuoles, peripheral cilia and dense nucleus, corresponding to Balantidium coli trophozoites.

ABSTRACT

Abstract Tumours of the appendix are rare and tend to be diagnosed incidentally, in cases of acute appendicitis. For some authors, appendiceal neuroendocrine tumours (ANETs) are the most frequent neoplasm of the appendix, observed in 0.3% to 0.9% of cases acute appendicitis. The present is a unicentric retrospective study conducted between January 2005 and March 2017. Out of a total of 3,007 surgeries for appendiceal pathologies performed in the adult population at the hospital where the present study was conducted, there were 70 (2.33%) malignant cases, 20 (28.6%) of which were ANETs. The patients had a median age of 44 years (range: 18 to 85 years), and were predominantly women (there were 1.9 times more women than men). In 16 cases (80%), a simple appendicectomy was performed (1 patient was submitted to a right hemicolectomy later). The cases of ANETs had a good prognosis in our series: 85% of the patients are either alive today or were alive after 5 years of follow-up. Despite the fact that ANETs are described as the most frequent tumor of the appendix, this was not confirmed in our series, in which they only represented 28.6% of the cases; adenocarcinoma was the most frequent tumor (65.7%) among our sample.


Resumo Tumores do apêndice são raros, e tendem a ser diagnosticados de forma incidental, em casos de apendicite aguda. Para alguns autores, tumores neuroendócrinos do apêndice (TNEAs) são as neoplasias mais frequentes do apêndice, e são observados em 0,3 a 0,9% de todos os casos agudos de apendicite. Este é um estudo monocêntrico e retrospectivo realizado entre janeiro de 2005 e março de 2017. Entre umtotal de 3.007 cirurgias para patologias do apêndice realizadas na população adulta no hospital em que o estudo foi conduzido, houve 70 (2,33%) casos de malignidade, 20 (28,6%) dos quais eram TNEAs. Os pacientes tinham uma idade média de 44 anos (gama: 18-85 anos), e eram predominantemente mulheres (havia 1,9 vezes mais mulheres do que homens). Em 16 casos (80%), realizou-se uma simples apendicectomia (1 paciente foi submetido a uma hemicolectomia direita mais tarde). Os casos de TNEAs tiveram um bom prognóstico em nossa série: 85% dos pacientes estão vivos hoje, ou estavam após um seguimento de 5 anos. Apesar de os TNEAs serem descritos como os tumores mais frequentes do apêndice, isso não foi confirmado nesta série, na qual eles representaram apenas 28,6% dos casos; adenocarcinoma foi o tumor mais frequente (65,7%) emnossa amostra.

ABSTRACT

Dar a conocer una presentación inusual de una patología frecuente. Se presenta caso de paciente masculino de 27 años con cuadro clínico de apendicitis aguda. Se realiza apendicetomía abierta en la cual se identifican dos apéndices vermiformes. Se confirma el diagnóstico por medio de anatomía patología, una con apendicitis aguda perforada y otra con peri-apendicitis. Es importante el conocimiento de esta patología para que se pueda reconocer y evitar errores de juicio durante el procedimiento quirúrgico y futuras complicaciones para el paciente. (AU)


Report an unusual presentation of a common pathology. A case of a 27-year-old male with a clinical picture of acute appendicitis is presented. An open appendectomy is performed in which two vermiform appendages are identified. The diagnosis is confirmed by pathology, one with perforated acute appendicitis and the other with peri-appendicitis. Knowledge of this pathology is important so that errors of judgment can be recognized and avoided during the surgical procedure and future complications for the patient. (AU)

ABSTRACT

Introducción: El mucocele es una dilatación apendicular por secreción mucosa secundaria a la obstrucción de la luz, su incidencia estimada es de 0,2-0,3 por ciento de todas las apendicectomías realizadas y el 8-10 por ciento de todos los tumores apendiculares. Objetivo: Presentar un caso inusual de cirugía de urgencia, con dolor abdominal en fosa ilíaca derecha, sugestivo de apendicitis aguda operado en el servicio de urgencia. Caso clínico: Paciente femenina de 32 años de edad, que consulta por dolor abdominal en fosa ilíaca derecha asociado a náuseas, con dolor a la palpación en dicha zona, defensa muscular y dolor a la descompresión brusca del abdomen, fue intervenida quirúrgicamente con el diagnóstico presuntivo apendicitis aguda. Se encuentra durante videolaparoscopia al apéndice cecal aumentado de tamaño, sin compromiso de su base, por lo cual se decide realizar laparotomía y apendicectomía convencional. La paciente fue egresada a las 48 horas de operada con evolución favorable y pendiente de resultado anatomopatológico, el cual informó mucocele apendicular. Conclusiones: El mucocele apendicular es una entidad poco frecuente, que predomina en el sexo femenino y edades entre 50 y 60 años. El tratamiento de elección es el quirúrgico(AU)


Introduction: The mucocele is the abnormal mucous accumulation inside the light of the appendix. Objective: To present an unusual case of surgery of urgency with abdominal pain and suspicion of appendicitis operated in emergency. Clinical case: Female patient of 32 years old that consults for abdominal pain in the right iliac fossa, accompanied by nausea. Physical examination we find pain to the palpation in the right iliac fossa and peritoneal reaction being operated with suspicion of appendicitis, during intervention we find the appendix augmented of volume and apendicectomy was made. The histopathological study informed a apendicular mucocele. The patient was discharged after 48 hours without further complications. Conclusions: Apendicular mucocele is very uncommon disease that predominates in female sex and persons between fifty and sixty years old. Treatment is surgical(AU)

ABSTRACT

Resumen La tuberculosis gastrointestinal es una manifestación extrapulmonar poco frecuente, correspondiendo al 3% de los casos y que compromete principalmente la región ileocecal; la afectación apendicular es poco frecuente. La apendicitis tuberculosa se puede presentar como un cuadro agudo indistinguible de las otras causas de apendicitis y el diagnóstico generalmente se hace por el hallazgo histopatológico, lo que retrasa el tratamiento y puede llevar a complicaciones. El período posparto es de riesgo de una reactivación de una tuberculosis, debido a cambios en el sistema inmunológico que se manifiestan como un síndrome de reconstitución inmune. Se presenta el caso de una paciente puérpera que ingresa por un choque séptico secundario a una apendicitis perforada. La histopatología demostró una inflamación granulomatosa crónica, con posterior confirmación por biología molecular de una tuberculosis pulmonar.


Abstract Gastrointestinal tuberculosis is a rare extrapulmonary manifestation, it represents 3% of cases and mainly involves the ileocecal region; appendiceal involvement is rare. Tuberculous appendicitis can present as an acute condition indistinguishable from other causes of appendicitis and the diagnosis is generally made by histopathological finding, which delays treatment and can lead to complications. The postpartum period is at risk of a reactivation of tuberculosis, due to changes in the immune system that manifests as an immune reconstitution syndrome. We present the case of a postpartum patient admitted for septic shock secondary to perforated appendicitis, the pathology reported chronic granulomatous inflammation and subsequent confirmation by molecular technique of pulmonary tuberculosis.

ABSTRACT

Background: Surgeons sometimes perform appendectomies during abdominopelvic surgeries for surgical conditions unrelated to the appendix. A retrospective study of the histopathological diagnoses of incidental appendectomy specimens was performed to see the value of this practice. Materials and Methods: Records of incidentally resected appendices submitted to the Histopathology Department of the University of Benin Teaching Hospital from January 2005 to December 2014 were reviewed retrospectively. Results: A total of 129 histopathological reports of incidental appendectomy were retrospectively reviewed; 67 (51.9%) of the patients were male and 62 (48.1%) were female, giving a male­female ratio of about 1.1:1. Fifty­four cases (41.9%) had histologically normal appendices, while 75 cases (58.1%) had various histopathologically demonstrable lesions ranging from acute appendicitis (the most frequent with 27%) to neoplasia (one case of mucinous adenocarcinoma). Conclusion: Significant pathology can be uncovered on histopathological examination of the clinically normal appendix. Incidental appendectomy is thus a useful procedure

ABSTRACT

PURPOSE: Appendiceal tumoral lesions can occur as benign, malignant, or borderline disease. Determination of the extent of surgery through accurate diagnosis is important in these tumoral lesions. In this study, we assessed the accuracy of preoperative CT and identified the factors affecting diagnosis.METHODS: Patients diagnosed or strongly suspected from July 2016 to June 2019 with appendiceal mucocele or mucinous neoplasm using abdominal CT were included in the study. All the patients underwent single-incision laparoscopic cecectomy with the margin of cecum secured at least 2 cm from the appendiceal base. To compare blood test results and CT findings, the patients were divided into a mucinous and a nonmucinous group according to pathology.RESULTS: The total number of patients included in this study was 54 and biopsy confirmed appendiceal mucinous neoplasms in 39 of them. With CT, the accuracy of diagnosis was 89.7%. The mean age of the mucinous group was greater than that of the nonmucinous group (P = 0.035). CT showed that the maximum diameter of appendiceal tumor in the mucinous group was greater than that in the nonmucinous group (P < 0.001). Calcification was found only in the appendix of patients in the mucinous group (P = 0.012). Multivariate analysis revealed that lager tumor diameter was a factor of diagnosis for appendiceal mucinous neoplasm.CONCLUSION: The accuracy of preoperative diagnosis of appendiceal mucinous neoplasms in this study was 89.7%. Blood test results did not provide differential diagnosis, and the larger the diameter of appendiceal tumor on CT, the more accurate the diagnosis.

ABSTRACT

OBJECTIVE@#To evaluate the effect of tumor-stroma ratio (TSR) on disease progression and prognosis of pseudomyxoma peritonei (PMP) from the appendix.@*METHODS@#The study included 30 PMP patients with complete individual patient data, who underwent cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) in Beijing Shijitan Hospital. Image-Pro Plus was used to quantitatively analyze the proportion of tumor and stromal areas in hematoxylin-eosin staining pathological images, from which TSR was derived. Correlation studies were conducted to evaluate the relationships between TSR and clinicopathological features, immunohistochemical characteristics, and prognosis of PMP.@*RESULTS@#Among 30 PMP patients, there were 16 males (53.3%) and 14 females (46.7%), with the mean age of (54.9±2.3) years. There were 15 cases (50.0%) of low-grade mucinous carcinoma peritonei (LMCP) and high-grade mucinous carcinoma peritonei (HMCP), respectively, with vascular tumor emboli occurring in 4 cases (13.3%), nerve invasion occurring in 3 cases (10.0%), and lymphatic metastasis occurring in 4 cases (13.3%). The median peritoneal cancer index (PCI) score was 36 (range: 3-39). The median TSR was 8% (range: 2%-24%), with TSR≤10% in 19 cases (63.3%) and TSR>10% in 11 cases (36.7%). Immunohistochemistry showed that 16 cases (53.3%) had Ki67 label index ≤ 50% and 14 cases (46.7%) > 50%. The mutation rate of p53 was 56.7% and the loss rate of MMR protein was 11.8%. In addition, the expression rates of MUC2, MUC5AC, CDX2, CK7, and CK20 were 66.7%, 100.0%, 82.6%, 56.0%, and 92.3%, respectively. There were significant correlations between TSR and histopathological types, nerve invasion, Ki67 label index, and p53 mutation (P<0.05 for all). At the end of the last follow-up, 21 patients (70.0%) died and 9 patients (30.0%) survived, including 6 patients survived with tumor. The median overall survival (OS) was 12.7 months (95%CI: 10.4-11.5 months), and the 1-, 2-, and 3-year survival rates were 60.5%, 32.3%, and 27.7%, respectively. The median OS was 19.4 months (95%CI: 3.0-35.9 months) in the TSR≤10% group, versus 12.6 months (95%CI: 0.7-24.5 months) in the TSR>10% group (χ2=3.996, P=0.046).@*CONCLUSION@#TSR is correlated with histopathological types, tumor proliferation, invasion behaviors and prognosis of PMP, thus could be a new prognostic indicator for PMP.
