[Characteristics of laparoscopic interventions in the patients with calculous cholecystitis complicated with hepatic cirrhosis].

Operative interventions in the patients suffering calculous cholecystitis on the hepatic cirrhosis background are accompanied by multiple complications. During ten year period laparoscopic cholecystectomy was conducted in the clinics in 138 patients suffering hepatic cirrhosis. In 12 patients, admitted to the hospital for obturation jaundice, endoscopic retrograde cholangiopancreaticography and endoscopic papillotomy were primarily done. In 3-7 days after successful removal of calculi from the ducts the laparoscopic cholecystectomy was performed. In 39 (28.3%) of patients complications had occurred, the most frequent of which was intraabdominal hemorrhage, as well as gastrointestinal bleeding from the varicosely changed esophageal veins in the early postoperative period--in 15 (10.8%). Two patients died as a consequence of postoperative hemorrhage occurring from varicosely changed esophageal veins, developed on the hepatocellular insufficiency background.

Mediators, secreted by lymph node cells shortly after immunization and draining the site of the injection of the antigen, produced a nonspecific activating effect on cells of the macrophagal series. The preventive injection of immune lymph node factors induced an increase in nonspecific resistance to S. typhi TU2 [correction of Ty2] No. [correction of N]4446.
