[Correction of bile outflow in complicated calculous cholecystitis].

The method of low-traumatic atypical endoscopic papillosphincterotomy (EPST) with an antegradely inserted probe which permits to correct simultaneously bile outflow in choledocholithiasis and strictures of the terminal part of the common bile duct was used in 26 patients with cholelithiasis. Advantage of this surgical policy in complicated forms of calculous cholecystitis is possibility of one-stage treatment. Comparative analysis of one-stage and routine two-stage treatment policies was carried out in 52 patients. EPST permits to avoid stage of retrograde pancreatocholangiography and papillosphincterotomy. Absence of technical difficulties due to EPST and a protective role of the probe which minimizes risk of acute pancreatitis are demonstrated.
