¿Plastrón o tumor apendicular? / Plastron appendicitis or appendiceal tumor?

Un plastrón apendicular es una masa apendicular palpable que contiene el apéndice inflamado, vísceras adyacentes y el omento mayor, asociado a o no a la presencia de pus. El manejo del plastrón apendicular abscedado es controvertido. Cuando hay signos de sepsis asociados, la indicación es una intervención quirúrgica de urgencia, de lo contrario puede optarse por un tratamiento conservador. La utilización de drenaje percutáneo tiene una alta tasa de efectividad, aunque la tasa de neoplasias no detectadas presenta un porcentaje no despreciable, especialmente en los pacientes mayores de 40 años. El objetivo de esta presentación es comunicar una paciente de 65 años con diagnóstico presuntivo de plastrón apendicular abscedado quien luego del fracaso de los drenajes percutáneos fue sometida a una laparotomía exploratoria y hemicolectomía derecha. El diagnóstico histopatológico fue de adenocarcinoma mucinoso del apéndice. (AU)

A palpable inflammatory appendiceal mass may contain the inflamed appendix, adjacent viscera, and the greater omentum, associated or not with the presence of pus. The management of an inflammatory appendiceal mass is controversial. When there are associated signs of sepsis, the indication is emergency surgery, otherwise, you can opt for a conservative treatment. The use of percutaneous drainage has a high rate of effectiveness, although the rate of undetected neoplasia is not negligible, especially in patients older than 40 years. We present the case of a 65-year-old female patient with a presumptive diagnosis of an appendiceal mass with abscess, who underwent exploratory laparotomy and right hemicolectomy after percutaneous drainage failure. The histopathological diagnosis was mucinous adenocarcinoma of the appendix. (AU)

Persistencia de uraco en paciente joven. Reporte de caso / Persistence of urachus in a young patient. Case report

Introducción. Durante el desarrollo embrionario normal, se espera que el denominado uraco o ligamento umbilical mediano se oblitere a las 32 semanas de gestación. Ante una obliteración incompleta surgen las diferentes anomalías, siendo las más frecuentes el quiste y la fístula urinaria umbilical. El objetivo de este artículo fue presentar el caso de una paciente joven, sin comorbilidades, con quiste de uraco. Caso clínico. Mujer indígena de 19 años que consultó por dolor leve en hipogastrio, asociado a síntomas urinarios y distensión abdominal. Se sospechó en primera instancia cólico renal, pero ante hallazgos ecográficos de masa infraumbilical y reactantes de fase aguda elevados, la impresión diagnóstica cambió a sepsis secundaria a absceso intraabdominal. Posterior a tomografía y cistoscopía con calibración uretral se identificó pequeño divertículo en cúpula vesical, que sugirió el diagnóstico de uraco persistente, por lo que la paciente fue llevada a intervención quirúrgica para su resección, con evolución favorable. Discusión. El quiste de uraco es una anormalidad infrecuente, en su mayoría asintomática y generalmente de hallazgo incidental en la población anciana, por lo que se requiere de imágenes y manejo multidisciplinar para su correcto diagnóstico y abordaje. Conclusión. Son pocos los casos de uraco persistente reportados, y mucho menos en el sexo femenino. Dada la posibilidad de complicaciones tardías es importante el seguimiento para su manejo. Este caso se ha controlado de manera ambulatoria por 2 años

Introduction. During normal embryonic development, it is expected that the so-called urachus or median umbilical ligament will be obliterated at 32 weeks of gestation. In the face of incomplete obliteration, the different anomalies of the urachus arise. The most frequent anomaly of the urachus is the cyst followed by the umbilical urinary fistula. The objective of this article was to present the case of a young patient without comorbidities with urachal cyst. Clinical case. A 19-year-old indigenous woman consulted for mild hypogastric pain associated with urinary symptoms and abdominal distension. Renal colic was suspected at first, but due to ultrasound findings of an infraumbilical mass and high acute phase reactants, the diagnostic impression changed to sepsis secondary to an intra-abdominal abscess. After tomography and cystoscopy with urethral calibration, a small diverticulum was identified in the bladder dome, suggesting a diagnosis of persistent urachus, for which the patient was taken to surgery for its resection, with favorable evolution. Discussion. The urachal cyst is a rare abnormality, mostly asymptomatic and usually incidental finding in the elderly population. Imaging and multidisciplinary management are required for its correct diagnosis and approach. Conclusion. There are few reported cases of persistent urachus and much less in females. Given the possibility of late complications, follow-up is important for its management, in this case we have carried out control for 2 years

Apendicitis aguda y el riesgo de tumor maligno oculto. Presentación de un caso y revisión sistemática de la literatura / Acute appendicitis and the risk of hidden malignant tumor. Presentation of a case and systematic review of literature

Introducción: Los tumores apendiculares representan aproximadamente 1% de los tumores malignos del intestino grueso. Más del 50% de las neoplasias primarias del apéndice se manifiestan inicialmente como apendicitis aguda. Métodos: Se reporta caso de paciente masculino que presentó adenocarcinoma invasor en biopsia de pieza quirúrgica de apéndice cecal tras apendicectomía, tomando la decisión de realizar hemicolectomía derecha laparoscópica diferida. Discusión: En este caso y como en la mayoría de los reportes de la bibliografía mundial, el adenocarcinoma simula un cuadro de AA. En un metaanálisis y una revisión sistemática de 2.771 pacientes diagnosticados de masa apendicular inflamatoria (flemón o absceso), Andersson et al. encontró 31 con tumores malignos. Estas lesiones se detectan en el 0,9% al 1,4% de las apendicectomías realizadas para tratar la AA. Conclusión: Este subtipo histológico presenta mayor incidencia de metástasis en los ganglios linfáticos y la supervivencia global era del 47,5%. Es por ello por lo que abogamos por la resección colónica como tratamiento definitivo del adenocarcinoma de apéndice cecal.

INTRODUCTION: Appendulular tumors represent approximately 1% of malignant tumors of the large intestine. More than 50% of the primary neoplasms of the appendix initially manifest as acute appendicitis. Methods: Men's patient who presented invading adenocarcinoma in Cecal Appendix Surgical Party Biopsy after appendectomy, making the decision to perform deferred laparoscopic right hemicolectomy, is reported. Discussion: In this case and as in most world literature reports, adenocarcinoma simulates an AA picture. In a meta -analysis and a systematic review of 2,771 diagnosed patients of inflammatory appendicular mass (phlegmon or abscess), Andersson et al. He found 31 with malignant tumors. These lesions are detected at 0.9% to 1.4% of appendectomies made to treat the AA. Conclusion: This histological subtype has a greater incidence of metastasis in lymph nodes and global survival was 47.5%. That is why we advocate colonic resection as a definitive treatment of cecal appendix adenocarcinoma.

An unexpected pathogen causing multiple intra-abdominal abscesses in an immunocompetent patient / Un patógeno inesperado como causa de múltiples abscesos intrabdominales en un paciente inmunocompetente

Abstract Streptococcus constellatus is a member of the group now called Streptococcus anginosus. This microorganism is part of the normal oropharyngeal, gastrointestinal and genitourinary microbiota. However, it may cause serious infections such as pharyngitis, bacteremia and invasive pyogenic infections in immunocompromised patients. We report the first case in Colombia of an adult male with no relevant medical history and with an unusual presentation of infection by S. constellatus and whose laboratory results showed an important systemic inflammatory response and radiographic evidence of abdominal involvement with poor response to medical and surgical management. Since there are few reports in international medical journals about intra-abdominal infection by S. constellatus and taking into consideration the need of a multidisciplinary intervention, this report may be of interest for both clinical and surgical practitioners.

Resumen Streptococcus constellatus es un miembro del grupo ahora llamado Streptococcus anginosus. Este microorganismo es parte de la microbiota orofaríngea, gastrointestinal y genitourinaria normal. Sin embargo, puede causar infecciones graves como faringitis, bacteriemia e infecciones piógenas invasivas en pacientes inmunocomprometidos. Presentamos el primer caso en Colombia de un hombre adulto sin antecedentes médicos relevantes y con una presentación inusual de infección por S. constellatus, dada por una gran respuesta inflamatoria sistémica y evidencia radiográfica de afectación abdominal con mala respuesta al tratamiento médico y quirúrgico. Dado que hay pocos informes en revistas médicas internacionales sobre la infección intraabdominal por S. constellatus y teniendo en cuenta la necesidad de intervenciones multidisciplinarias, este reporte puede ser de interés tanto para los médicos clínicos como para los quirúrgicos.

Abscesso gástrico após biópsia endoscópica: relato de caso e revisão da literatura / Gastric abscess after endoscopic biopsy: case report and literature review

Paciente apresenta dispepsia, vômitos e dor epigástrica uma semana após EDA com biópsia. Exames revelaram elevação de marcadores inflamatórios e tomografia contrastada do abdome, um espessamento parietal circunferencial do corpo gástrico e da região antropilórica. Nova EDA mostrou lesão na grande curvatura do antro, no local onde foi realizada a biópsia endoscópica, com drenagem de secreção purulenta e enantema, condizente com diagnóstico de abscesso gástrico. Realizados antibioticoterapia e drenagem endoscópica com sinais clínicos de melhora. Terceira EDA evidenciou resolução da lesão. Paciente recebeu alta hospitalar em uso de amoxicilina e clavulanato por 10 dias.O abscesso gástrico é uma rara infecção da submucosa e da muscular própria e sua patogênese envolve foco de injúria à mucosa gástrica por trauma penetrante, disseminação de infecções contíguas, fontes de infecção ou casos idiopáticos. Desconforto epigástrico é o sintoma predominante, associado ou não a náusea, vômitos, febre e calafrios. Alterações laboratoriais incluem leucocitose com desvio à esquerda e elevação de marcadores inflamatórios. A propedêutica é realizada por meio de EDA, TC de abdome e ecoendoscopia. A cultura da drenagem purulenta é útil no diagnóstico e no tratamento, sendo o Streptococcus o patógeno mais comum. Antibioticoterapia, associada à drenagem percutânea ou endoscópica é o pilar do tratamento. Cirurgia está reservada para dúvidas diagnóstica, falha de tratamentos menos invasivos ou peritonite.Devido à raridade dos abscessos gástricos e à ausência de marcadores específicos, o diagnóstico requer um alto grau de suspeição e deve ser confirmado por exames endoscópicos e de imagem. É importante também, incluir essa condição nos diagnósticos diferenciais dos tumores intramurais gástricos.

Patient presents dyspepsia, vomiting and epigastric pain one week after upper digestive endoscopy (UDE) with biopsy. Tests revealed elevation of inflammatory markers and contrasted tomography of the abdomen, a circumferential parietal thickening of the gastric body and the anthropiloric region. New UDE showed lesion in the great curvature of the antrum, where the endoscopic biopsy was performed, with purulent secretion and enanthema, consistent with the diagnosis of gastric abscess. Antibiotic therapy and endoscopic drainage evidenced clinical signs of improvement. Third UDE showed resolution of the lesion. Patient was discharged using amoxicillin and clavulanate for 10 days.Gastric abscess is a rare infection of the submucosa and the muscle layer. The pathogenesis involves a focus of injury to the gastric mucosa by penetrating trauma, dissemination of contiguous infections, sources of infection or idiopathic cases. Epigastric discomfort is the predominant symptom, associated with nausea, vomiting and fever. Laboratory changes include leukocytosis with left shift and elevation of inflammatory markers. Propaedeutics is performed by means of UDE, abdominal CT and echoendoscopy. The culture of purulent drainage is useful in diagnosis and treatment, Streptococcus is the most common pathogen. Antibiotic therapy and percutaneous or endoscopic drainage is the mainstay of treatment. Surgery is reserved for diagnostic doubts, failure of less invasive treatments or peritonitis.Due to the rarity of gastric abscesses and the absence of specific markers, the diagnosis requires a high degree of suspicion and must be confirmed by endoscopic and imaging testes. It is also important to include this condition in the differential diagnoses of gastric intramural tumors.

Un estudio comparativo de complicaciones agudas Apendicitis en el Hospital Universitario Al-Basra. Un estudio clínico prospectivo / A Comparison Study of Acute Complicated Appendicitis in Al-Basra Teaching Hospital. A Prospective Clinical Study

Background: Acute appendicitis is one of the most frequent surgical emergencies and is a common cause of non-traumatic acute abdominal emergencies that require surgical intervention. Most complicated appendicitis started de novo as simple appendicitis raising the notion that it is a disease in evolution that has become of clinical importance due to delayed or missed diagnosis. Complicated appendicitis has been associated with a significant risk of postoperative septic complications, including wound infections and intra-abdominal abscess formation. This study aimed to evaluate the types of complicated appendicitis and their relationship to patient's demographic data, postoperative course and the length of hospital stay in Al-Basra Teaching Hospital. Methods: This was a prospective clinical study involving patients with acute appendicitis admitted to Al-Basra Teaching Hospital from January 2017 to October 2019. The demographic data, types of complicated appendicitis, hospitalization duration, and postoperative complications were evaluated. The patients were divided into six groups according to age. All data were recorded and analyzed. Results: A total of 1210 patients, age from 6 to 69 years, mean age of patients was 23.45, males out-numbered females. Perforated appendicitis represents the main type of complicated appendicitis, and it was reported mostly among elderly patients. Patients with complicated appendicitis had a longer hospitalization and more postoperative complications than patients with non-complicated appendicitis. Conclusion: we concluded that nearly one third of the patients with acute appendicitis had complicated appendicitis, so they need a special pre and postoperative care and old age had non classical clinical picture with poor outcome.

Association of intraperitoneal ceftriaxone, intravenous gentamicin and oral metronidazole in the treatment of an abdominal abscess and peritonitis in a horse: case report / Associação da ceftriaxona intraperitoneal, gentamicina intravenosa e do metronidazol oral no tratamento de abscesso abdominal e peritonite em equino: relato de um caso

Medical management of abdominal abscesses in horses requires prolonged antibiotic therapy and presents varied success rates. A 6-year-old male horse with a history of colic and multiple abdominal punctures to relieve gas was attended. At admission, tachycardia, tachypnea, hyperthermia, mucosal congestion, dehydration, and rigid gait were observed. The association of physical examination, laboratory and ultrasonographic findings allowed the diagnoses of peritonitis and abdominal abscess. Supporting treatment plus broad spectrum antibiotic therapy was performed: daily intraperitoneal ceftriaxone (25 mg/kg, 7 days); daily intravenous gentamicin (6.6 mg/kg, 7 days); per os metronidazole three times a day (15 mg/kg 12 days), followed by the same dose twice a day (15 mg/kg 33 days), totaling 45 days of treatment. Plasma fibrinogen and ultrasonographic examination were the most effective tools to evaluate abscess evolution. There was normalization of the physical examination 24 h after beginning the treatment, consecutive regression of the nucleated cell count in the peritoneal fluid, and regression of plasma fibrinogen and size of the abscess. On the 10th treatment day, the animal was discharged from the hospital, maintaining oral therapy with metronidazole every 12 h (15 mg / kg). When the animal returned on the 30th day, an abscess size regression was observed. However, there was no resolution, and therapy with metronidazole was maintained. On the 45th day of treatment, a new hospital evaluation was performed, where the abscess resolved, and metronidazole was suspended. It is highlighted that the therapeutic association used in the treatment of abdominal infection and abscess resulted in a rapid clinical response.(AU)

O tratamento conservativo dos abscessos abdominais em equinos requer antibioticoterapia prolongada e apresenta variadas taxas de sucesso. Foi atendido um cavalo de seis anos de idade, com histórico de cólica e múltiplas punções abdominais por agulha para esvaziamento de gás. Na admissão, foram observados taquicardia, taquipnéia, hipertermia, congestão mucosa, desidratação e marcha rígida. A associação do exame físico, achados laboratoriais e ultrassonográficos permitiu o diagnóstico de peritonite e abscesso abdominal. Foi realizado tratamento suporte e antibioticoterapia de amplo espectro: ceftriaxona intraperitoneal diária (25 mg/kg, 7 dias); gentamicina intravenosa diária (6,6 mg/kg, 7 dias); metronidazol oral três vezes ao dia (15 mg/kg, 12 dias), seguido de mesma dose duas vezes ao dia, por mais 33 dias, totalizando 45 dias de tratamento. O fibrinogênio plasmático e o exame ultrassonográfico foram os recursos mais eficazes para a avaliação da evolução do abscesso. Após 24 horas do início do tratamento foi constatada a normalização do exame fisico, regressão progressiva da contagem de células nucleadas no líquido peritoneal, do fibrinogênio plasmático e do tamanho do abscesso. No 10° dia de tratamento o animal recebeu alta hospitalar, mantendo-se a terapia oral com metronidazol a cada 12 horas (15 mg/Kg). Em retorno, ao 30° dia, observou-se regressão do tamanho do abscesso, entretanto, não houve resolução, tendo sido mantida a terapia com metronidazol. No 45º dia de tratamento, realizou-se nova avaliação hospitalar, onde foi observada a resolução do abscesso e a admnistração do metronidazol foi suspensa. Destaca-se, que a associação terapêutica utilizada no tratamento de infecção abdominal e abscesso resultou em rápida resposta clínica.(AU)

Term Delivery following ruptured tubo-ovarian abscess in early pegnancy / Philippine Journal of Obstetrics and Gynecology

@#Tubo-ovarian abscess in pregnancy is extremely rare. Its occurrence increases the maternal and fetal morbidities and mortalities. The clinical presentation is variable ranging from asymptomatic abscess to diffuse peritonitis. In this report, we present a rare case of tubo-ovarian abscess complicating a pregnancy on its 6 weeks and 5 days age of gestation. The patient presented with frank peritonitis. Internal examination revealed uterine, adnexal and cervical tenderness with no masses palpated. A laparotomy was done and intra-operative findings showed an 8 x 4 cm-sized, right, ruptured tubo-ovarian abscess with purulent contamination of the whole pelvic cavity. Right salpingooophorectomy was performed and parenteral antibiotics were given. The pregnancy was eventually carried to term and the patient delivered by repeat low segment cesarean section without fetal and maternal complications.

Predictors of treatment failure of medical management among patients with pelvic inflammatory disease with tubo-ovarian abscess admitted in a tertiary hospital

@#OBJECTIVE: This study aimed to identify the predictors for treatment failure of medical management among admitted female patients diagnosed with pelvic inflammatory disease with tubo-ovarian abscess. METHODS: This was a retrospective nested case-control study, using chart review of all cases of pelvic inflammatory disease with tubo-ovarian abscess/complex (N = 49) admitted at the Department of Obstetrics and Gynecology, Philippine General Hospital from January 1, 2014 to December 31, 2018. RESULTS: Medical treatment failure was observed to be significantly higher (51.9%) among patients 40 years old and above as compared to patients less than 40 years old (13.6%). The risk of patients ≥40 years for failed management was 14x higher than those <40 years old (OR=14.00; 95% CI=1.06 to 185.5;p=0.04). The failed management group has significantly higher TOA size of 7.8 (7.8 ± 1.6) as compared to only 5.8 (5.8 ± 1.4) for medical treatment alone group. Correspondingly, those who failed have a significantly bigger volume of 120.4 ml (120.4 ± 84.5) as compared to only 55.2 ml (55.2 ± 40.6) for medical treatment alone group. Other predictive factors such as parity, admitting White blood cell count(WBC), C-Reactive Protein (CRP), and neutrophil-lymphocytic ratio(NLR) were all not significant. CONCLUSION: Tubo-ovarian abscess size of more than or equal to 7 cm, or a volume of more than or equal to 120 ml and advanced age of >40 were all predictive of failed response to medical treatment. Early recognition and intervention whether surgery or drainage may be beneficial to reduce morbidity and long-term sequelae of PID.

Effects of pneumoperitoneum and trendelenburg position on intraocular pressure (IOP) in isofluorane anesthetised cats / Efeitos do pneumoperitônio e da posição de trendelenburg sobre a pressão intraocular em gatos anestesiados com isoflurano

The aim of this study was to determine whether a pneumoperitoneum of 10 mmHg combined or not with the Trendelenburg position could lead to significant changes in intraocular pressure (IOP), ocular pressure perfusion (OPP), and cardiorespiratory variables; as well as determine whether a correlation exists between IOP and mean arterial blood pressure (MAP), and/or partial pressure of carbon dioxide in arterial blood (PaCO2) in cats. Animals were allocated in two groups (n=7/group): GC (without inclination) and GTREN (Trendelenburg position). The variables were recorded before (baseline) and during 30 minutes (T5-T30) after insufflation. In GTREN, a reduction in heart rate was observed at T5 and in respiratory rate at T5 and T15. There was an increase in IOP at T5-T30 in comparison to baseline. There was a reduction in potential of hydrogen in arterial blood in both groups at all times in comparison to baseline. Partial pressure of carbon dioxide in arterial blood was increased at T15-T30 in GC and at T5-T30 in GTREN. In conclusion, the pneumoperitoneum of 10mmHg CO2 did not significantly affect IOP or OPP in cats anaesthetised with isofluorane and kept under spontaneous ventilation. However, induced pneumoperitoneum combined with Trendelenburg position resulted in an increase in IOP in cats subjected to the same anaesthetic conditions, but did not affect OPP.

O objetivo deste estudo foi determinar se o pneumoperitônio de 10 mmHg associado, ou não, à posição de Trendelenburg poderia levar a alterações significativas na Pressão Intraocular (PIO), Pressão de Perfusão Ocular (PPO) e variáveis cardiorrespiratórias, bem como determinar se havia correlação entre a PIO e a Pressão Arterial Média (PAM) e/ou Pressão Parcial de Dióxido de Carbono no Sangue Arterial (PaCO2) em gatos. Os animais foram alocados em dois grupos (n = 7/grupo): GC (sem inclinação) e GTREN (posição de Trendelenburg). As variáveis foram registradas antes (linha de base) e durante 30 minutos (T5-T30) após a insuflação. No GTREN, foi observada redução na frequência cardíaca em T5 e, na frequência respiratória, em T5 e T15. Houve aumento da PIO no T5-T30 comparativamente ao valor basal. Houve redução no Potencial de Hidrogênio no sangue arterial em ambos os grupos em todos os momentos comparativamente à linha de base. A Pressão Parcial de Dióxido de Carbono no sangue arterial aumentou em T15-T30 no GC e em T5-T30 no GTREN. Concluiu-se que o pneumoperitônio de 10mmHg CO2 não afetou significativamente a PIO ou a PPO em gatos anestesiados com isofluorano e mantidos sob ventilação espontânea. No entanto, o pneumoperitônio induzido combinado à posição de Trendelenburg resultou em aumento da PIO em gatos submetidos às mesmas condições anestésicas, mas não afetou a PPO.

Factores de riesgo para la aparición de abscesos intrabdominales tras la apendicectomía / Risk factors for the appearance of intra-abdominal abscesses after appendectomy

RESUMEN Introducción: Los abscesos intrabdominales son las complicaciones posapendicectomía que más frecuentemente provoca ingresos hospitalarios. Objetivo: Estudiar los factores de riesgo para la aparición de abscesos intrabdominales posapendicectomía. Métodos: Se realizó un estudio retrospectivo de pacientes mayores de 14 años, intervenidos por sospecha de apendicitis aguda mediante apendicectomía laparoscópica, desde el 1 de enero de 2007 al 31 de diciembre de 2010. Se utilizaron los tests estadísticos Chi cuadrado, Prueba exacta de Fisher, T de Student y regresión logística. Resultados: Durante los 4 años del estudio, 672 pacientes padecieron con síntomas y signos compatibles con apendicitis aguda. Apareció un absceso intrabdominal en 35 casos (5,2 por ciento). En el análisis multivariante mediante regresión logística se constataron como posibles factores de riesgo: las formas avanzadas de apendicitis (p < 0,0001), las cuales aumentaron el riesgo en unas 6 veces (IC 95 por ciento 2,2-14,9) y el sexo masculino (p = 0,033), también podrían aumentar el riesgo unas 2,5veces (IC 95 por ciento 1-6). Conclusiones: Los posibles factores de riesgo para la aparición de abscesos intrabdominales tras apendicectomía son el sexo masculino y el estadio avanzado, siendo este último el factor más influyente(AU)

ABSTRACT Introduction: Intra-abdominal abscesses are the post-appendectomy complications that most frequently cause hospital admissions. Objective: To study the risk factors for the appearance of post-appendectomy intra-abdominal abscesses. Methods: A retrospective study of patients over 14 years of age, operated on for suspected acute appendicitis by laparoscopic appendectomy, was performed from January 1, 2007 to December 31, 2010. Chi-square statistical tests, Fisher's exact test were used. Student's t and logistic regression. Results: During the 4 years of the study, 672 patients suffered with symptoms and signs compatible with acute appendicitis. An intra-abdominal abscess appeared in 35 cases (5.2 percent). In the multivariate analysis using logistic regression, the following possible risk factors were found: advanced forms of appendicitis (p < 0.0001), which increased the risk by about 6 times (95 percent CI 2.2-14.9) and male sex (p = 0.033), could also increase the risk about 2.5 times (95 percent CI 1-6). Conclusions: Possible risk factors for the appearance of intra-abdominal abscesses after appendectomy are male sex and advanced stage, the latter being the most influential factor(AU)

Abscesos residuales en apendicitis aguda: comparación entre abordaje laparotómico vs. laparoscópico / Residual abscesses in acute appendicitis: comparison between laparotomy vs. laparoscopic / Abcessos residuais na apendicite aguda: comparação entre laparotômico vs. laparoscópico

La apendicitis aguda es la urgencia quirúrgica más frecuente con una incidencia de 1.17 pacientes/1,000 habitantes. Con el advenimiento de la laparoscopía, un nuevo enfoque mini invasivo surgió para el tratamiento de la apendicitis aguda. Se han demostrado algunas ventajas de este abordaje como menor dolor posoperatorio, incisiones más pequeñas, estadías hospitalarias más cortas y un rápido reintegro a las actividades diarias y laborales, con menor frecuencia de infecciones a nivel de la herida operatoria. Sin embargo, se ha asociado también con un aumento en la frecuencia de abscesos residuales intra-abdominales. En este trabajo analizamos de manera retrospectiva a todos los pacientes operados en el Hospital Maciel de Montevideo, a los que se les realizó una apendicectomía entre el 1° de Junio de 2013 y el 30 de junio de 2016, tanto por vía laparoscópica como laparotómica. Esto correspondió a un total de 426 pacientes. 235 (55%) eran hombres y 191 (45%) mujeres. La media de edad fue de 32,6 en un rango desde los 15 años hasta los 96 años de edad. 128 pacientes presentaban apendicitis edematosas (30%), 157 apendicitis flemonosa (36,9%) 76 pacientes apendicitis gangrenosas (17,8%) 37 pacientes absceso o plastrón (8,7%) y peritonitis en 28 pacientes (6,6%). Con respecto al abordaje, 287 se realizaron por vía laparoscópica (67,4%) y 139 se abordaron por vía laparotómica (32,6%). Los abscesos residuales representan el 3,28% del total, no habiendo diferencias significativas entre los diferentes abordajes. La gran mayoría de estos abscesos residuales pueden tratarse con antibioticoterapia exclusivamente. La tasa de conversión fue del 8,7%. No se observaron lesiones de víscera hueca con el abordaje laparoscópico en esta serie.

Acute appendicitis is the most frequent surgical emergency with an incidence of 17 patients/1,000 inhabitants. With the advent of laparoscopy, a new mini-invasive approach emerged for the treatment of acute appendicitis. Some advantages of this approach have been demonstrated, such as less postoperative pain, smaller incisions, shorter hospital stays and a rapid reintegration to daily and work activities, with a lower frequency of infections at the level of the operative wound. However, it has also been associated with an increase in the frequency of intra-abdominal residual abscesses. In this paper, we retrospectively analyzed all patients operated on at the Maciel Hospital in Montevideo, who underwent an appendectomy between June 1, 2013 and June 30, 2016, both laparoscopically and laparotomically. Of these 235 (55%) were men and 191 (45%) women. The average age was 32.6 in a range from 15 years to 96 years of age. 128 patients presented edematous appendicitis (30%), 157 phlegmonous appendicitis (36.9%), 76 patients gangrenous appendicitis (17.8%), 37 patients presented abscess or plastron (8.7%), and peritonitis had developed in 28 patients (6.6%). Regarding the approach, 287 were performed laparoscopically (67.4%) and 139 were approached via laparotomy (32.6%). The residual abscesses rate represents 3.28% of the series, with no significant differences in incidence between the two different approaches. The vast majority of these residual abscesses can be treated with antibiotic therapy alone. The conversion rate was 8.7%. No intestinal lesions were observed with the laparoscopic approach in this series.

A apendicite aguda é a emergência cirúrgica mais freqüente, com uma incidência de 17 pacientes/1.000 habitantes. Com o advento da laparoscopia, uma nova abordagem mini-invasiva surgiu para o tratamento da apendicite aguda. Isto têm demonstrado algumas vantagens, como menor dor pós-operatória, incisões menores, menor hospitalização e restabelecimento mais rápido as atividades diárias e ao trabalho, assim como infecções menos freqüentes ao nível da ferida cirúrgica. No entanto, também foi associado a um aumento na freqüência de abscessos residuais intra-abdominais. Foram analisados retrospectivamente todos os pacientes operados no Hospital Maciel de Montevidéu, submetidos a uma apendicectomia desde o dia 01 de Junho de 2013 a 30 de Junho de 2016, tanto por abordagem laparoscópica como laparotomica. Destes, 235 (55%) eram homens e 191 (45%) mulheres. A idade média foi de 32,6 com intervalo de 15 anos a 96 anos de idade. 128 pacientes apresentaram apendicite edematosa (30%), 157 apendicite flemonosa (36,9%) 76 pacientes apendicite gangrenosa (17,8%) 37 pacientes abscesso ou plastrão (8,7%) e peritonite em 28 pacientes (6,6% ) Quanto à abordagem, foram realizadas 287 apendicectomias por via laparoscópica (67,4%) e 139 foram abordadas por laparotomia (32,6%). Os abscessos residuais representam 3,28% do total, não havendo diferenças significativas entre as diferentes abordagens. A grande maioria desses abscessos residuais pode ser tratada apenas com antibioticoterapia. A taxa de conversão foi de 8,7% Nenhuma lesão visceral foi observada com a abordagem laparoscópica nesta série.

Manejo del drenaje percutáneo guiado por imágenes en un hospital de tercer nivel / Management of imaging guided percutaneous drainage at a third level of care Colombian hospital

Introducción. El drenaje percutáneo de las colecciones intraabdominales, guiado por ultrasonografía o por tomografía computadorizada, ha sido el tratamiento de elección para los abscesos abdominales o pélvicos, entre otros. Objetivo. Describir la experiencia en el manejo percutáneo de colecciones abdominales en pacientes del Hospital Universitario San José de Popayán entre octubre de 2014 y abril de 2016. Materiales y métodos. Se trata de una serie de casos de 79 pacientes a quienes se les hizo manejo intervencionista de colecciones abdominales por medio de cirugía percutánea guiada por imágenes, los cuales cumplieron con los criterios de inclusión y exclusión. El análisis estadístico se hizo con el programa SPSS Statistics™. Resultados. Se realizaron 106 procedimientos percutáneos para drenar diferentes colecciones intraabdominales. La intervención más frecuente fue el drenaje de colecciones hepáticas (32,1 %), en su mayoría, abscesos hepáticos, seguida del drenaje de abscesos posquirúrgicos de cirugías abiertas o laparoscópicas. Conclusiones. Las técnicas intervencionistas en manos de un cirujano entrenado son un tratamiento eficaz y seguro para las diferentes colecciones intraabdominales. El procedimiento fue exitoso en el 99 % de los pacientes de la presente serie

Introduction: Percutaneous drainage of intraabdominal collections guided by ultrasonography or computerized axial tomography has been the treatment of choice for the management of abdominal or pelvic abscesses. Objective: To describe the experience with the percutaneous ultrasonography-guided drainage of abdominal collections in patients at the San José University Hospital in Popayán, Colombia, in the period October 2014 and April 2016. Materials and methods: This is a case series of 79 patients who underwent interventional management of abdominal collections by a percutaneous procedure guided by images; all patients met the inclusion and exclusion criteria. The statistical analysis was carried out with the SPSS Statistics program. Results: 106 percutaneous procedures were performed for drainage of different intra-abdominal collections. The most frequent intervention was the drainage of hepatic collections (32.1%), mostly hepatic abscesses, followed by drainage of postoperative abscesses following open or laparoscopic surgery. Conclusions: The management of interventional techniques in the hands of the trained surgeon is an effective and safe method for the treatment of different intra-abdominal collections. The procedure was successful in 99% of the patients

Endoscopic Ultrasound-Guided Transgastric Drainage of an Intra-Abdominal Abscess following Gastrectomy

Endoscopic ultrasound (EUS)-guided transgastric drainage has been performed as a less invasive procedure for pancreatic fistulas and intra-abdominal abscesses occurring after surgery in recent years. However, there are no reports of EUS-guided transgastric drainage of intra-abdominal abscesses following gastrectomy. This case report describes 2 patients who developed an intra-abdominal abscess following gastrectomy and underwent EUS-guided transgastric drainage. Both patients underwent laparoscopy-assisted distal gastrectomy with Billroth-I reconstruction for gastric cancer. The intra-abdominal abscesses were caused by postoperative pancreatic fistula that developed following gastrectomy. One patient underwent naso-cystic drainage and the other underwent only a needle puncture of the abscess cavity. EUS-guided drainage was performed safely and effectively, although 1 patient developed gastroduodenal anastomotic leakage related to this procedure. In summary, EUS-guided transgastric drainage is safe and technically feasible even in post-gastrectomy patients. However, it is necessary to be careful if this procedure is performed in the early period following gastrectomy.

Explantation of Adjustable Gastric Bands: An Observation Study of 10 Years of Experience at a Tertiary Center

PURPOSE: Although laparoscopic adjustable gastric bands are considered a standard treatment for severe obesity, their use remains controversial. We evaluated rates of band explantation and the incidences of complications leading to and following band explantation. MATERIALS AND METHODS: This retrospective review was performed on patients that underwent adjustable gastric band explantation. For each of the three groups of patients that underwent explantation, we compared demographic and anthropometric data, band duration in situ, operative approach, and morbidities. RESULTS: Between January 2009 and October 2018, a total of 267 patients underwent primary laparoscopic adjustable gastric band surgery. Of these 267 patients, 99 (37.1%) underwent band explantation. Numbers (%) of patients in the slippage (SL), band erosion (BE), and intolerance (IT) groups were 13 (13.1%), 39 (39.4), and 47 (47.5%), respectively. Mean %EBMIL values at explantation in these groups were 74.6±45.5, 79.7±40.3, and 36.1±46.0, respectively (p<0.001), and mean times for maintaining bands in situ were 45.1±28.0, 39.4±24.3, and 51.2±22.7 months, respectively. Isolated band removal was performed for slippage (SLi, n=12), band erosion (BEi, n=39), and intolerance (ITi, n=31). The numbers (%) of patients in the SLi, BEi, and ITi groups that experienced a surgical complication (Clavien-Dindo class ≥1) were 0 (0.0%), 24 (61.5%), and 3 (9.7%), respectively (p<0.001). In the BEi group, four patients (4/39, 10.3%) underwent reoperation after AGB removal. CONCLUSION: During our 10 years of experience, 37.1% of adjustable gastric band had to be removed. Intra-abdominal abscess and intragastric bleeding were rare but serious complications after explantation. Potential candidates for adjustable gastric band should be informed of the high long-term risk of band explantation and its associated morbidities.

Cáncer de colon con infiltración a pared abdominal: un reto diagnóstico / Colonic cancer with infiltration to the abdominal wall: a diagnostic challenge

Se presenta el caso de una paciente mujer de 53 años procedente de Piura con un tiempo de enfermedad de 20 meses, caracterizado por dolor en sitio de herida quirúrgica por colecistectomía abierta realizada hace 3 años, asociado a presencia de una masa en dicha zona, posteriormente se absceda y comienza a drenar secreción alimentaria. Los estudios de imágenes revelaron una masa dependiente de colon transverso en contacto con estómago y pared abdominal que presentaba fistulas hacia piel. Dicha masa fue extraída durante la cirugía con resultado anatomopatológico de adenocarcinoma mucinoso de colon. El caso representó un reto diagnóstico para el equipo médico y en vista de las diversas manifestaciones clínicas del cáncer de colon, sugerimos mantenerlo presente como diagnóstico diferencial en cuadros de absceso de pared abdominal y fistulizaciones entéricas.

We present the case of a 53-year-old woman with a time of illness of 20 months, characterized by pain at the site of surgical intervention for opened cholecystectomy 3 years ago, associated with a presence of a mass in said area, with the following abscess formation and fistulization of food content. Imaging studies revealed a mass dependent of the transverse colon, in contact with stomach and abdominal wall and presenting fistulas to the skin. Said mass was extracted during surgery with anatomopathological result of mucinous colon adenocarcinoma. The case represented a diagnostic challenge for the medical team and in view of the variaty of clinical manifestations of colonic cancer, we suggest that it should be consider as a differential diagnosis in cases of abdominal wall abscess and enteric fistulas.

Current management of spontaneous intra-abdominal abscess in Crohn's disease / Tratamento atual de abscesso intra-abdominal espontâneo na doença de Crohn

ABSTRACT Crohn's disease (CD) is a chronic transmural disease process with approximately 10% of patients developing spontaneous intra-abdominal abscess during the first 5 years after the diagnosis. The symptoms are often nonspecific. The treatment modalities include the use of wide-spectrum antibiotics, imaging-guided percutaneous drainage (PD) and surgical drainage with or without resection. The best initial treatment strategy has not been settled controversial, as there are only retrospective studies with small sample sizes available in the literature. The majority of the patients would eventually need surgery. However a highly selected patient population with small abscess in the absence of fistulas or bowel strictures, especially those naive to immunomodulators or biologics, may respond to medical treatment alone with wide-spectrum antibiotics. The increased use of PD drainage in the last few years has been shown to reduce postoperative morbidities and risk of fecal diversion, allowing for subsequent elective surgery. Varied success rates of PD drainage have been reported in the literature. The initial surgical intervention of CD-related spontaneous abdominal sepsis is mandatory in patients with diffuse peritonitis due to free perforation. Surgery is also indicated in those with failed initial medical treatment and/or PD. This review article was aimed to evaluate the treatment modalities for spontaneous intra-abdominal abscess in CD patients and propose an algorithm for the best management of this complication.

RESUMO A doença de Crohn (DC) é um processo patológico transmural crônico, em que aproximadamente 10% dos pacientes desenvolvem um abscesso intra-abdominal espontâneo durante os primeiros 5 anos após o diagnóstico. Com frequência os sintomas são inespecíficos. As modalidades terapêuticas são o uso de antibióticos de amplo espectro, drenagem percutânea (DP) orientada por imagem, e drenagem cirúrgica com ou sem ressecção. A melhor estratégia terapêutica inicial ainda não ficou estabelecida e há controvérsias, visto que a literatura conta apenas com estudos retrospectivos com pequenas amostras. Em sua maioria, os pacientes acabarão necessitando de cirurgia. Mas uma população altamente selecionada de pacientes, com pequeno abscesso na ausência de fístulas ou constrições intestinais, especialmente aqueles que jamais foram medicados com imunomoduladores ou agentes biológicos, podem responder exclusivamente ao tratamento clínico com antibióticos de amplo espectro. Foi demonstrado que o uso mais frequente da DP nos últimos anos diminui as morbidades pós-operatórias e o risco de desvio fecal, o que possibilita uma subsequente cirurgia eletiva. Na literatura, têm sido relatados percentuais de sucesso variados com a DP. A intervenção cirúrgica inicial para a sepse abdominal espontânea relacionada à DC é obrigatória em pacientes com peritonite difusa, devido à perfuração livre. Também há indicação cirúrgica naqueles pacientes que não conseguiram obter sucesso com o tratamento clínico inicial e/ou DP. Esse artigo de revisão teve por objetivo avaliar as modalidades terapêuticas para o abscesso intra-abdominal espontâneo em pacientes com DC; além disso, propõe um algoritmo para o melhor tratamento dessa complicação.
