Aim: To analyze treatment of patients with de novo extrahepatic bile ducts lesions., Material and Methods: The study included 37 patients with post-cholecystectomy biliary leakage which was confirmed intraoperatively and in postoperative period. Cystic duct stump failure was observed in 18 (55.3%) patients, marginal damage, complete intersection and excision of extrahepatic bile duct wall occurred in 7 (18.4%), 1 (2.6%) and 1 (2.6%) patients respectively. Injury of the duct of Lyushka was revelaed in 8 (21.1%) patients., Results and Discussion: Endobiliary stenting was performed in 32 (84.2%) patients. It was final independent method in 5 (13.2%) cases and combined with other procedures in 27 patients (drainage and puncture of bile accumulations (28.9%), laparoscopic external drainage of biliary ducts (42.1%)). The greatest efficacy of these interventions was proved for cystic duct stump failure - 21 of 21 (100.0%), marginal damage of bile ducts - 7% out of 7 (100%), as well as for intersection of ducts of Lychka - 6 out of 8 (75%)., Conclusion: Complex application of minimally invasive surgical interventions for extrahepatic bile ducts injury after cholecystectomy reduces likelihood of redo biliary surgery and may be independent treatment in some cases.

Aim: To define the role of endoscopic interventions in diagnosis and treatment of Mirizzi syndrome., Material and Methods: Results of treatment of 41 patients with Mirizzi syndrome are presented. Endoscopic transpapillary interventions including cholangiography, papillosphincterotomy lithoextraction, nazobiliary drainage were used as a first step in all cases., Results and Discussion: In 4 cases laparoscopic cholecystectomy was performed after biliary tree sanitation. In 6 advanced age patients with severe comorbidities common bile duct stenting alone was preferred. Open interventions were performed in 15 patients (36.6%) including cholecystectomy, choledocholithotomy with common bile duct drainage., Conclusion: It is shown that endoscopic transpapillary methods of diagnosis and treatment of Mirizzi syndrome provides adequate decompression and sanitation of the bile ducts in most cases and significantly reduces number of open surgical procedures.
