There are few descriptions of association between chagasic megacolon and colon cancer. We report a case of obstructive abdomen caused by adenocarcinoma of the left colon in chagasic megacolon. A review of the literature revealed 8 cases of this association and, analyzing together the series of findings of cancer in chagasic organomegalies, we found a frequency of 4.8% in megaesophagus and 0.1% ...

Toxic megacolon is a rare and serious complication of Crohn's disease. Because of the associated high morbidity and mortality, early recognition and management of toxic megacolon is important. Through two cases of toxic megacolon complicating Crohn's disease, we assessed the clinical, radiologic and therapeutic characteristics of this complication. A 35-year-old man presented a first course of ...

BACKGROUND Trypanosomiasis induces a remarkable myenteric neuronal degeneration leading to megacolon. Very little is known about the risk for colon cancer in chagasic megacolon patients. To clarify whether chagasic megacolon impacts on colon carcinogenesis, we investigated the risk for colon cancer in Trypanosoma cruzi (T. cruzi) infected patients and rats. METHODS Colon samples from T. cruzi...

The distinction between Hirschsprung's disease and idiopathic megacolon in childhood dates from the classic clinical, radiological, and histological studies of Bodian, Stephens, and Ward. This article describes clinical experience over 15 years of 94 patients in whom megacolon of these two types was recognised for the first time after the age of 10, to illustrate the problems of diagnosis and t...

Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is now a well established entity [1,2]. Also known as Berdon syndrome [1], it is characterized by massive abdominal distension caused by a largely dilated non obstructed urinary bladder, microcolon and decreased or absent intestinal peristalsis. Isolated cases of congenital megacystis [3,4] and microcolon without megacystis [5] h...

BACKGROUND Rectoanal inhibitory reflex is not always evident in patients with chagasic megacolon. This may be due to insufficient volumes of air used during insufflation for the manometric examination. AIMS To identify the volume of air necessary to induce rectoanal inhibitory reflex in patients with chagasic megacolon and to observe its prevalence in these individuals. METHODS Rectoanal in...

Introduction: Colon cancer is the most frequent cause of colonic obstruction which usually manifested by distention, bloating, and pain. Colonic with a competent ileocecal valve risk factor for complications such as ischemia, necrosis, perforation, but toxic megacolon seldom mentioned in literature. Case report: This case describes patient left sided colon presenting initially obstructive sympt...

Megacolon must be considered as a diagnosis in any case of intractable constipation also in the adult. Besides the Hirschsprung's disease and the idiopathic megacolon, which have no apparent organic cause, many other pathologic conditions may produce a marked dilatation of the large bowel. The differential diagnosis depends, after a valuation of the clinical and radiologic features, also from e...
