iatrogenic perforation of the colon during elective colonoscopy is a serious complication. surgical treatment remains the standard of care. we report a patient with a large colonic perforation that occurred during a screening colonoscopy, successfully repaired with laparoscopic methods. although the safety and efficacy of this approach is not entirely established, laparoscopy can be used to tre...

Some, but not all, studies have suggested that high-fat diets promote colon carcinogenesis, possibly by stimulating the proliferative activity of colonic epithelium. Both the increase in colonic excretion of bile salts and of fatty acids that occur with an increase in fat ingestion have been implicated as stimuli of epithelial proliferative activity. In this study, we examined the role of activ...

Manometric and pharmacological tests have shown that motor abnormalities may occur in the non-dilated colons of chagasic patients. In order to investigate the presence of abnormalities of colonic function in constipated patients with Chagas' disease (ChC) without megaesophagus or megacolon, studies of total and segmental colonic transit time with radiopaque markers were performed on 15 ChC pati...

Lesson Colonic lipomas are rare benign tumours that usually asymptomatic. However, giant colonic tend to be symptomatic and can occasionally result in intussusception intermittent obstruction. As adult is an uncommon occurrence, the identification of underlying aetiology essential due its high association with malignancy. Computed Tomography remains tool choice for diagnosis lipomas. Surgical e...

UNLABELLED The aim of the study was to assess (quantitatively) colonic hydrogen absorption. Hydrogen volumes in flatus and breath were measured over periods of six hours in normal subjects during fasting and after ingestion of the non-absorbable carbohydrate lactulose to simulate the effect of fermentable dietary fibres. If less than 76 ml/6 h of hydrogen accumulated in the colon then all of it...
