[The diagnostic significance of endoscopic retrograde cholangio-pancreatography in so-called post-cholecystectomy syndrome (authors transl)].

A total of 47 patients with symptoms of socalled post-cholecystectomy syndrome was investigated using endoscopic retrograde cholangio-pancreatography (ERCP). An organic cause was found in 31 cases; pathological findings were recorded in the biliary tract in 20 cases, in the pancreatic system in 4 cases and in other organs in the remaining 7 cases. ERCP is a very valuable method for pre- and postoperative examination of the patient. When complaints after cholecystectomy exist, organic changes of the biliary and extrabiliary system have to be excluded. In the majority of pancreatic and biliary disorders an optimum diagnostic evaluation is only possible with the aid of ERCP. This method represents a valuable additional tool for preoperative diagnosis in respect to the indications for biliary surgery and the surgical management of the case, especially when re-operation has to be considered.
