Nevertheless, lethality after elective surgery in group of patients older 60 years increase in proportional to their age. Using drainage operations on gallbladder is improve the results of the treatment of patients with high operation and anaesthetic risk. Residual concrements of gallbladder favour to develop acute cholecystitis relapse and their rehospitalization at once. Demucotisation of gallbladder cavity is alternative cholecystectomy and one of the prospective method, favour to decrease the lethality in that group of patients. In this study authors shows advantages and disadvantages of chemical and bipolar mucoclasy of gallbladder and also gives an experimental studying of new method - thermal mucoclasy of gallbladder.
