Megacolon tóxico: peritonitis fecaloidea por colitis amebiana. Reporte de un caso y revisión de literatura / Toxic megacolon: fecaloid peritonitis caused by amebic colitis. Report of a case and literature review

Introducción: La amebiasis es una enfermedad causada por el parásito Entamoeba histolytica, y condiciona importantes tasas de afectación a escala global. Una de las complicaciones de la colitis amebiana es el megacolon tóxico, el cual se caracteriza por la dilatación colónica y signos de toxicidad sistémica. Aunque poco frecuente, el megacolon tóxico es considerado letal.Caso clínico : se trata de paciente femenino de 26 años, quien consulta por presentar dolor abdominal generalizado, de fuerte intensidad, tipo cólico, acompañado de náuseas y múltiples episodios eméticos. Al examen físico se precisó hemodinámicamente estable, sin signos de irritación peritoneal, por lo que es ingresada con diagnóstico de colitis amebiana. Se instaura manejo médico y es egresada por mejoría clínica. Luego de 7 días, es readmitida por deterioro clínico y distensión abdominal, realizándose diagnóstico de megacolon tóxico. Mediante laparotomía de emergencia se observa peritonitis fecaloidea difusa y perforación del ciego, se realiza hemicolectomía derecha e ileostomía terminal. Posteriormente, presenta absceso intraabdominal que fue drenado por vía percutánea. Conclusión : el megacolon tóxico es una patología infrecuente que surge como complicación de entidades como la colitis amebiana. En la actualidad, a pesar de los avances tecnológicos que han desencadenado importantes progresos en el ámbito sanitario, el diagnóstico del megacolon tóxico continúa representando un desafío para el profesional médico, por lo que la sospecha clínica es ineludible y determinante en el diagnóstico acertado y oportuno, que permiten la instauración de la terapéutica apropiada y reducción de la morbilidad y mortalidad que de esta se derivan(AU)

Introduction: Amebiasis is a disease caused by the parasite Entamoeba histolytica, and causes significant rates of infection on a global scale. One of the complications of amoebic colitis is toxic megacolon, which is characterized by colonic dilation and signs of systemic toxicity. Although rare, toxic megacolon is considered lethal. Clinical case: this is a 26-year-old female patient, who consults due to generalized abdominal pain, of strong intensity, colic type, accompanied by nausea and multiple emetic episodes. On physical examination she was found to be hemodynamically stable, with no signs of peritoneal irritation, so she was admitted with a diagnosis of amoebic colitis. Medical management was established and she was discharged due to clinical improvement. After 7 days, she was readmitted due to clinical deterioration and abdominal distention, and a diagnosis of toxic megacolon was made. Through emergency laparotomy, diffuse fecaloid peritonitis and perforation of the cecum were observed; right hemicolectomy and terminal ileostomy were performed. Subsequently, she developed an intra-abdominal abscess that was drained percutaneously. Conclusion: toxic megacolon is a rare pathology that arises as a complication of entities such as amoebic colitis. Currently, despite the technological advances that have triggered important progress in the healthcare field, the diagnosis of toxic megacolon continues to represent a challenge for the medical professional, which is why clinical suspicion is unavoidable and decisive in an accurate and timely diagnosis, which allow the establishment of appropriate therapy and reduction of the morbidity and mortality that arise from it(AU)

A Rare Case Of Peritonitis Due To Ulcerative Amoebic Colitis - Case Report

ULCERATIVE AMOEBIC COLITIS is a rare complication of amoebiasis that is associated with high mortality. Only 1 to 4 cases are seen per year in India & only few such cases have been reported. This requires early diagnosis and surgical intervention. We recently cared for a patient who presented with acute abdomen with history of Abdominal pain,Fever,Obstipation. Before presenting to our institution he was admitted at outside private hospital for 2 days in view of Left Diabetic FOOT with ACUTE KIDNEY INJURY with SEPSIS and was treated conservatively.On emergency exploration, MULTIPLE CAECAL PERFORATIONS with extensive necrosis of Ascending COLON were seen. SEGMENTAL RESECTION OF 5 CM TERMINAL ILEUM,CAECUM,ASCENDING COLON and 5 CM TRANSVERSE COLON was performed. Postoperative course was marked by septicaemia and multi-organ failure followed by death. This case report emphasizes the importance of early diagnosis and treatment of acute AMOEBIC COLITIS and associated high mortality.

Colitis amebiana necrosante, presentación de un caso / Necrotizing amebian colitis, case report

Resumen Introducción: La Organización Mundial de la Salud (OMS) y la Organización Panamericana de la Salud (OPS) han definido la amebiasis como la infección por Entamoeba histolytica, independientemente de los síntomas. La colitis amebiana necrosante es una forma rara de amebiasis que se asocia con una alta morbilidad y mortalidad. Caso clínico: Presentamos a un paciente femenino de 68 años, con antecedentes de diabetes mellitus tipo 2, con colitis amebiana necrosante con múltiples perforaciones, que fue sometida a una hemicolectomía derecha con íleo-transverso anastomosis. Conclusiones: Se necesitan intervenciones efectivas para prevenir la colitis amebiana y terapias adicionales para tratar la colitis amebiana fulminante y mejorar los resultados.

Abstract Background: Amebiasis has been defined by World Health Organization (WHO) and Pan American Health Organization (PAHO) as the infection with Entamoeba histolytica regardless of symptoms. Necrotizing amoebic colitis is a rare clinical form of amebosis that is associated with high morbidity and mortality. Case Report: We present a 68-years-old-female patient with necrotizing amoebic colitis with multiple perforations who survived after right hemicolectomy with ileus-transverse anastomosis. Conclusions: Effective interventions to prevent amebic colitis, and additional therapies to treat fulminant amebic colitis are needed to improve outcomes.

A Case Of Amoebic Colitis With Unusual Presentation

Amoebiasis is a parasitic infection caused by Entamoeba histolytica occurring in populations with low socio-economic status and is transmitted by faeco-oral route. It mainly involves the intestine and liver and presents as acute abdomen and loose stools. A 73 years old female presented with pain in abdomen and loose stools since 2 days. Radiological investigations revealed inflammation of the appendix and thickening of the colonic wall and clinical presentation prompted emergency surgical intervention with a suspicion of Crohn's disease clinically and a postoperative diagnosis of amoebic colitis was made on histopathology

A Rare Case of Caecal Perforation with Ruptured Amoebic Liver Abscess.

Amoebic colitis is a common infection in all population groups across all geographical barriers and is an easily treatable disease in its routine manifestations. However, he has its set of complications that carry poor prognosis. Amoebic liver abscess is a common complication but its association with caecal perforation is rare, and carries worst prognosis. No survivors have been documented in the available literature and the result was pretty much the same in our study.

Fulminant necrotising amoebic colitis: A diagnostic conundrum

Fulminant necrotising amoebic colitis is a complication of untreated amoebiasis. This is seen in mainly low-income countries. It has a high mortality rate and is difficult to diagnose. We present an extremely rare case of fulminant necrotising amoebic colitis that caused diagnostic confusion in mimicking an acute abdomen, presumably caused by a perforated duodenal ulcer.

Perforación intestinal secundaria a amebiasis / Amebiasis intestinal perforation secondary

La amebiasis intestinal es una enfermedad frecuente en países en desarrollo, que es común en regiones tropicales y subtropicales, así como en regiones con servicios sanitarios deficientes. Presentamos el caso de un paciente de 74 años de edad, sexo masculino, originario y residente de la ciudad de Guatemala, quién cursó una diarrea y dolor abdominal. Fue intervenido quirúrgicamente por abdomen agudo, con resección intestinal extensa por perforaciones. En el estudio de anatomía patológica se realizó el diagnóstico de colitis amebiana con perforaciones y peritonitis.

Intestinal amoebiasis is a disease common indeveloping countries, which is common in tropicaland subtropical regions, as well as in regions withpoor sanitation. We report the case of a 74-year-oldmale, resident of Guatemala City, who presented withdiarrhea and abdominal pain. He had a laparatomy foracute abdomen, undergoing wide intestinal resectiondue to perforations. The pathology diag-nosis wasamoebic colitis with perforations and peritonitis.
