Therapeutic ERCP: spectrum of procedures performed in 60 consecutive patients.

Therapeutic applications of endoscopic retrograde cholangiopancreatography (ERCP) have increased dramatically, and endoscopic sphincterotomy (ES) is the cornerstone of these techniques. Indications include treatment of retained biliary duct stones, papillary stenosis, benign and malignant strictures, and acute cholangitis and pancreatitis. We reviewed our recent experience to assess the spectrum of procedures done and their results. Medical records and radiographic examinations in 60 consecutive patients undergoing therapeutic ERCP were studied. Patients were placed into one of three treatment groups; Group 1, ES alone (N = 21); Group 2, ES plus stone retrieval (N = 15); and Group 3, ES plus stent placement (N = 24). In Group 1, all of eight patients with ductal stones had spontaneous passage. In 11 patients with papillary stenosis, nine had relief of symptoms following ES. Two patients with pancreatitis improved after ES. In Group 2, all 15 patients with ductal stones had successful retrieval. In Group 3, patients were treated for biliary stricture alone (4), retained stones (7), pancreatitis (5), neoplasms (6) and papillary stenosis (2). In these 24 patient, 21 (88%) were treated successfully or had palliation of their symptoms. In our series, a wide variety of therapeutic applications of ERCP was used to manage simple and complex biliary disease. ES alone or in combination with other techniques was done in all patients. Overall, 55 (92%) of 60 interventional procedures were successful as defined by removal of stones and relief or palliation of symptoms.
