[Late results of endoscopic papillosphincterotomy treatment in patients with acute cholecystitis].

The authors examined 81 patients who were subjected to endoscopic papillosphincterotomy (EPST) in the management of acute cholecystitis attended by total or partial obstruction of the choledochus. Cholestomy was carried out before or after EPST in 68 patients but not in 13 patients. The duration of the follow-up period after treatment ranges from 12 months to 6 years. All patients who were examined felt well and had no complaints caused by cholelithiasis. It was found that destruction of the sphincter apparatus of the major duodenal papilla and terminal choledochus led to the development of reflux from the duodenum into the choledochus in 25% of cases. In 18 patients ultrasonic examination revealed signs of chronic pancreatitis which was not manifested clinically. Among 13 patients with a preserved gallbladder containing concrements only 3 were operated on during the follow-up period. Residual choledocholithiasis was found in 5 patients in whom during good bile drainage after EPST it was not manifested clinically. The authors come to the conclusion that EPST shows a high clinical efficacy in the treatment of acute cholecystitis complicated by obstruction of the terminal choledochus.
