[Prospects of intraoperative dynamic cholangio-manometry by tensor detectors with graphic recording of pressure function].

Intraoperative cholangio-manometry with a miniature tensor sensor and graphic recording of the results were conducted to study the function of the major duodenal papilla in 53 patients. A periodical activity of the ampulla of the papilla was revealed, which was characterized by certain values of the peak and basal pressure, and duration of contraction and relaxation periods. The numerical values and the pattern of the pressure curve differed in patients with obstructive cholecystitis, biliary pancreatitis, and a concrement incarcerated in the ampulla of the papilla.

[Lesions of the biliary system in primary extrahepatic portal hypertension].

The authors describe extensive strictures of the hepaticocholedochus, ranging from 2.5 cm in length to total involvement of the duct, in 15 patients with primary extrahepatic portal hypertension. In 7 patients they were combined with cystic dilatation of the intrahepatic bile ducts.

[Surgical tactics in the treatment of acute cholecystitis with lesions of the bile ducts].

The authors analyse the results of treatment of 185 patients with acute cholecystitis coexisting with affection of the bile ducts. In view of the high risk of operative treatment, endoscopic papillosphincterotomy was undertaken as the first stage in 83 patients and was completed by nasobiliary drainage in 46 of them, in still another 12 patients decompression was accomplished by means of laparoscopic cholecystostomy . Surgical intervention was carried out in the second stage after the patients recovered from a grave condition and obstructive jaundice and intoxication caused by purulent cholangitis were corrected.

[Surgical treatment of strictures of the hepaticocholedochus in patients with primary extrahepatic portal hypertension].

An analysis of their experience with treatment of 14 patients has shown that treatment of prolonged strictures of hepaticocholedochus in patients with extrahepatic portal hypertension by conservative measures is not sufficiently effective. The optimum surgical treatment is operation for reestablishment of the bile outflow. Hepaticojejunostomy is most reliable.

[Peritoneovenous shunt in resistant ascites in patients with portal hypertension].

Experience in 100 operations for the creation of a peritoneovenous shunt in 63 patients with portal hypertension and resistant ascites showed that in careful selection of patients and determination of contraindications this operation is an effective method for the treatment of resistant ascites in patients with portal hypertension. The shunt increases diuresis, reduces the volume of the abdomen, makes laparocentesis unnecessary, improves the patients' general condition and allows some of them to be prepared for interventions on the organs of the portal system which are more radical in character.
