[Therapeutic tactics in acute obstruction of the terminal part of the common bile duct].

The authors had 158 patients with acute block of the terminal part of the choledochus under observation. According to the clinical course, a biliary, pancreatic, and mixed forms were distinguished. The emergency diagnostic program was made up of ultrasonic examination, esophagogastroduodenoscopy, ERCP, and laparoscopy. The cause of the block of the terminal choledochus was choledocholithiasis in 104 patients, papillitis and microcholedocholithiasis in 36, and ++choledocholithiasis and stenosis of the major duodenal papilla in 18 patients. Acute block of the major duodenal papilla was found in 76 and acute block of the intramural part of the choledochus in 76 patients. The mixed form prevailed in the first and the biliary form of hypertension in the second. Operations (cholecystectomy, choledocholithotomy with external or internal drainage of the choledochus) were performed on 42 patients, the postoperative fatality rate was 9.7%. Emergency EPST and extraction of concrements was undertaken in 116 patients. Increase in the clinical picture of acute cholecystitis and destructive pancreatitis after EPST called for operative interventions on 21 patients. The lethality rate after EPST performed for acute block of the terminal choledochus was 6.1%.
