[The effectiveness of endoscopic retrograde cholangiopancreatography in the etiological diagnosis of postcholecystectomy syndrome].

A retrospective study of 249 with symptoms and signs of postcholecystectomy syndrome was made to evaluate the usefulness of endoscopic retrograde cholangiopancreatography (ER CP) in its etiological diagnosis. From 1693 ERCP evaluated, 1108 were checked and from these 249 patients showed symptoms and signs after the cholecystectomy. So they were selected to practice a diagnostic ERCP. 204 patients were females and its principal symptom was jaundice. Lesions found in most of the cases were: stones in the bile ducts (45.78%), benign biliary stenosis (8.3%), stenosis of vater's papilla (7.22%) and biliary fistula (7.22%). It can be conclude that biliary stones is the most frequent pathology in those patients with clinical suspicion of biliary-pancreatic organicity and that ERCP is the principal method of diagnosis in these patients.
