An assessment of the management of acute bleeding varices: a multicenter prospective member-based study.

Objective: Bleeding from esophagogastric varices is a major complication of portal hypertension. Despite recent practice guidelines for the management of bleeding esophageal or gastric varices, the widespread application of these measures by gastroenterologists has not been evaluated. The purpose of this study was to continue the concept of membership-based research within diverse practice settings by expanding the American College of Gastroenterology (ACG) GI Bleeding Registry to assess the management and outcome of acute variceal bleeding.

Colonic angiodysplasia.

Colonic angiodysplasia (AD) is an important vascular lesion responsible for approximately 6.0% of cases of lower gastrointestinal hemorrhage. Lesions are usually located in the right colon and, although the pathophysiology is unknown, most are probably acquired as the result of a degenerative process associated with aging.

The American College of Gastroenterology Bleeding Registry: preliminary findings.

Objectives: The American College of Gastroenterology (ACG) Institute for Clinical Research and Education conducted a survey study to assess demographics, management strategies, and outcome for patients with gastrointestinal bleeding. This pilot project was intended to determine the feasibility of surveying the ACG membership about common clinical issues.

Methods: Color-coded survey forms were sent to all ACG members and Fellows, with instructions to supply information about demographics, presenting symptoms, management, and outcome for bleeding patients and procedure-matched controls.

Diverticular bleeding and the pigmented protuberance (sentinel clot): clinical implications, histopathological correlation, and results of endoscopic intervention.

Unlabelled: Over a 3-yr period, we performed colonoscopy on five patients (mean age 71 yr) in whom a specific diverticulum that contained a pigmented protuberance (PiP) was unequivocally identified as the cause for hemorrhage. Four of these individuals had endoscopic bipolar cauterization of the PiP, and two patients had surgery.

Aim: To (1) determine the clinical significance of an intradiverticular PiP, (2) correlate endoscopic features of a PiP with histopathological findings and, (3) assess results of endoscopic treatment for affected patients with lower GI bleeding.
