A case of colonic pseudoobstruction related to bacterial overgrowth due to a sigmoidocecal fistula.

Colocolic fistulas are usually a complication of an inflammatory or neoplastic process. Development of these abnormal bowel communications may lead to bacterial overgrowth. We report on a 71-year-old man with a one-year history of recurrent abdominal distension and irregular bowel habits.

Cap-assisted ERCP in patients with difficult cannulation due to periampullary diverticulum.

Selective biliary cannulation is an essential prerequisite for therapeutic endoscopic retrograde cholangiopancreatography (ERCP). The cap-fitted forward-viewing endoscope has been used for ERCP in patients with surgically altered anatomy. In this case series, 12 patients with periampullary diverticulum underwent ERCP using the cap-assisted forward-viewing endoscope due to failure of biliary cannulation using the standard technique.
