Selective ERCP and preoperative stone removal in bile duct surgery

Abstract

This project was undertaken to evaluate in a prospective fashion the effects of selective preoperative endoscopic-retrograde cholangiography and stone extraction (ERCP-ST EXTR) on the results of biliary tract surgery. Over a 6-year period, 728 patients with primary or secondary biliary tract disease were admitted to the First Surgical Department, landeskrankenanstalten, Salzburg, Austria. If, based on preoperative screening, the possibility of common bile duct stones (CBDS) existed, the patients were subjected to ERCP-ST EXTR. Two to 4 days later, these patients underwent a simple cholecystectomy with intraoperative cholangiogram and functional manometry. Evaluation criteria for this study were morbidity, mortality, and retained stone (RST) rates. The overall complication rate for the entire series was 6%. In patients who underwent operative common duct stone removal (n = 78), the complication rate amounted to 21.8%. The rate was reduced to 2.1% by ERCP-ST EXTR. The RST rate was likewise reduced from 2.2% to 0.5% by ERCP-ST EXTR. Mortality in patients with CBDS fell from 3.8% to 1% through the use of this method. In those patients with secondary stones who were treated by ERCP-ST EXTR only, morbidity was 2%, the RST rate was 0%, and mortality was 0%. It is concluded that selective ERCP-ST EXTR, followed by simple cholecystectomy, is a suitable treatment protocol and that this approach may reduce complication and mortality rates.
