A novel tableted purgative for colonoscopic preparation: efficacy and safety comparisons with Colyte and Fleet Phospho-Soda.

Background: Currently available aqueous purgatives used before colonoscopy are poorly tolerated. We designed a tableted sodium phosphate purge that we believe will yield much greater patient acceptance.

Methods: A total of 305 outpatients undergoing routine diagnostic colonoscopy were randomized to one of three preparation groups: Colyte (100 patients), Fleet Phospho-Soda (106 patients), or sodium phosphate tablets (99 patients).

A multicenter, randomized, controlled trial to evaluate the effect of prophylactic octreotide on ERCP-induced pancreatitis.

Eight-four patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) were randomized to receive 100 micrograms of octreotide intravenously immediately prior to ERCP, and 100 micrograms subcutaneously 45 min after the initial dose, or placebo. Amylase, lipase, and glucose were measured and clinical assessment was performed before, and 2 and 24 h after, ERCP. We define clinical pancreatitis as the combination of elevated amylase or lipase with abdominal pain and tenderness.

Identification of Blastocystis hominis by colonic brush cytology. A case report.

Blastocystis hominis is a unicellular organism the pathogenic potential of which in humans remains unclear. It may be identified during a workup for gastrointestinal symptoms, usually in stool examined for ova and parasites. We describe a case in which B hominis was identified by cytologic examination in a patient with Crohn's disease who underwent colonoscopy and brushing of a transverse colon stricture.

Sincalide-aided ultrasonography of the common bile duct as a predictor of biliary obstruction determined by ERCP and biliary manometry.

Sonographically observed changes in common bile duct caliber following intravenous sincalide injection were correlated with distal common duct pathology as defined by endoscopic retrograde cholangiopancreatography and biliary manometry. Thirty-two patients, 17 with prior cholecystectomies, were studied. In post-cholecystectomy patients, a 1-mm or greater diminution of duct caliber within 5 min represented a normal response.

Ileocecal endometriosis presenting with abdominal pain and gastrointestinal bleeding.

A 26-year-old woman with enteric endometriosis presenting with cecocolic intussusception, a cecal mass on barium enema, and gastrointestinal hemorrhage is described. Laparotomy revealed cecocolic intussusception, ileocecal endometrial implants, and cecal mucosal ulceration presumed secondary to ischemia of the intussuscepted bowel. Histopathology showed serosal and subserosal endometrial implants without mucosal invasion.
