Fístula sigmoido-cervical secundaria a una enfermedad diverticular complicada / Sigmoido-cervical fistula due to diverticular disease

Resumen Introducción: Las fístulas secundarias a una enfermedad diverticular complicada son una indicación formal de cirugía electiva en el 4 a 23% de los casos. Caso Clínico: Se presenta el caso de una mujer de 52 años con antecedentes de una histerectomía subtotal por miomatosis uterina que consulta por cuadro de dolor abdominal en hipogastrio acompañado de fiebre de 4 días de evolución. La tomografía computada (TC) de abdomen y pelvis describe una diverticulitis complicada con absceso peridiverticular. Tratada con antibióticos con buena respuesta clínica consulta a los 3 meses en nuestro servicio por pérdida de material fecal por vagina. Nueva TC confirma la presencia de una colección perisigmoidea y engrosamiento de la pared vesical. La colonoscopía informa una estenosis franqueable a nivel de sigmoides y se constata salida de gases por vagina. La corrección quirúrgica electiva incluyó una sigmoidectomía abierta con traquelectomía en block, cierre de la cúpula vaginal y anastomosis colorrectal mecánica, con buena evolución posoperatoria, sin recidiva a los 12 meses de seguimiento. La fístula sigmoido-cervical es una complicación rarísima de la enfermedad diverticular complicada que puede ocurrir en pacientes sometidas a una histerectomía subtotal previa. Aunque el diagnóstico de la fístula es clínico, la colonoscopía y la TC permiten descartar otras etiologías. La resección radical del segmento afectado es el tratamiento estándar en pacientes aptos.

Introduction: Diverticular disease is complicated by fistulas in 4% to 23% of patients. Case Report: A woman 52 years-old previously operated on with parcial histerectomy was successfully treated with antibiotics due to diverticulitis complicated with an abscess. Three months later the patient presented with vaginal discharge of faeces. Computed tomography showed wall thickening of sigmoid colon and vesical wall. Colonoscopy exclude cancer and confirmed the exit of gas through vagina. En-bloc resection of the sigmoid colon with traquelectomy with primary anastomosis was performed. The postoperative course was good without recurrence after 12 months of follow up. Sigmoido-cervical fistula is a very rare benign fistula due to diverticular disease. Diagnosis is basically clinic, but tomography and colonoscopy are important to exclude other causes of fistulas. Radical surgery with primary anastomosis is the standard treatment.

Interdisciplinary investigation of occurrence of diverticular disease among patients referred for barium enema and colonoscopy studies at Dr. George Mukhari Academic Hospital, Ga-Rankuwa, Pretoria, South Africa

Background: Diverticular disease (DD) is believed to be a disease which is prevalent in developed countries. Contrary to this belief, DD has been reported with an increasing trend in prevalence in Africa for the past four decades. Objectives: The objective of this study was to highlight the increasing trend of DD and to corroborate barium enema findings obtained from Diagnostic Radiology Department, with colonoscopy results from the Surgery Department at Dr. George Mukhari Academic Hospital. Methods: Results for barium enema and colonoscopy investigations of all the patients referred over a 1-year period were retrospectively reviewed by two independent research groups; each of these groups was unaware of the research carried out in the Departments of Diagnostic Radiology and Surgery. Data from the records were analyzed with the Statistical Package for the Social Sciences (IBM SPSS, version 22.0), New York, USA, version 22.0. Results: Barium enema results of 166 patients were evaluated for DD, and out of these, 129 patients (77.7%) were negative, while 37 patients (22.3%) (95% confidence interval = 19.07­25.50) were positive. A review of 384 colonoscopy results also revealed positive evidence for 47 patients (13.5%) (95% confidence interval = 10.30­17.50) for DD and 337 patients (86.5%) were negative. The findings of barium enema and colonoscopy investigative studies were similar for female preponderance, diffuse pattern of distribution of DD and the mean age of patients. Conclusion: The two studies corroborate each other and have produced the highest number of diagnostic yield for DD in one year, in Africa

Colonoscopy in the diagnosis of acute lower gastrointestinal bleeding / A colonoscopia no diagnóstico da hemorragia digestiva baixa aguda

Lower gastrointestinal bleeding is defined as a bleeding originated from a source distal to the Treitz ligament and the colonoscopy is well established as the diagnostic procedure of choice. Objective: To evaluate the results of colonoscopies performed to diagnose the cause of acute lower gastrointestinal bleeding in a general hospital at Mato Grosso do Sul. Material and methods: Colonoscopy procedures performed in the Endoscopy service of the Hospital Regional de Mato Grosso do Sul in those patients admitted due to an acute lower gastrointestinal bleeding from January 2014 to December 2015 were analyzed retrospectively. The studied variables were age, gender, diagnosis and localization of the lesion. Results: The mean age was 66 years, and there was a little predominance of the male gender. Diverticular disease was the main cause of lower gastrointestinal bleeding in this study, followed by cancer, inflammatory gastrointestinal disease, polyps, and angiodysplasia. Conclusion: The colonoscopy showed to be an effective diagnostic method in the case of acute lower gastrointestinal bleeding and a good therapeutic tool in the case of diverticular disease and angiodysplasia.

Hemorragia digestiva baixa é definida como sangramento originado de uma fonte distal ao ligamento de Treitz e a colonoscopia esta bem estabelecida como o seu procedimento diagnóstico de escolha. Objetivo: Avaliar os resultados das colonoscopias realizadas para elucidação diagnóstica dos casos de Hemorragia digestiva baixa aguda em um Hospital Geral de Mato Grosso do Sul. Materiais e métodos: Foram analisadas, de forma retrospectiva, as colonoscopias realizadas nos pacientes internados devido à hemorragia digestiva baixa aguda, no período de janeiro de 2014 a dezembro de 2015, no serviço de endoscopia digestiva do Hospital Regional de Mato Grosso do Sul. As variáveis estudadas foram a idade, sexo, diagnóstico e localização da lesão. Resultados: A média de idade foi de 66 anos, com uma discreta predominância do sexo masculino. A doença diverticular foi a principal causa de hemorragia digestiva baixa nesse estudo, seguido de neoplasias, doença inflamatória intestinal, pólipos e angiodisplasia. Conclusão: A colonoscopia mostrou-se como método efetivo no diagnóstico dos casos de Hemorragia digestiva baixa aguda e como uma boa ferramenta terapêutica também nos casos de angiodisplasia.
