[Endoscopic contact lithotripsy--modern alternative in the therapy of patients with large stones of the common bile duct].

The peculiarities of therapeutic ERCP and contact lithotripsy in patients with choledocholithiasis were studied. 6516 patients (age from 11 to 94 years old) with choledocholithiasis were examined Endoscopic sphincterotomy/balloon dilation with stone extraction was effective in 5507 (84.5%), in 539 (8.8%)--we achieved bile ducts clearance by using mechanical or electrohydraulic lithotripsy. Additional usage of contact lithotripsy increased the effectiveness of therapeutic ERCP to 93.2%. Contact lithotripsy decreased number of specific for ERCP complication from 7.83% to 1.57% in patients with large (> 25mm) stones. Electrohydraulic lithotripsy was successful in destruction of hard bile stones, when mechanical lithotripsy failed.

[Endoscopic transpapillary methods of choledocholithiasis treatment, caused by presence of multiple calculi].

The results of endoscopic transpapillary surgical interventions in 115 patients, suffering choledocholithiasis, caused by the multiple calculi presence, were analyzed. The patients were divided on four groups, depending on the treatment provided. In 78 patients (first group) endoscopic papillosphincterotomy with mechanical lithoextraction in conjunction with spasmolytic and infusion therapy were performed. In 16 patients (second group) endoscopic papillosphincterotomy with mechanical lithotripsy and partial lithoextraction, endobiliary stenting with further spasmolytic and infusion therapy were performed. In 11 patients (the third group) endoscopic papillosphincterotomy, mechanical lithotripsy with a partial lithoextraction and nasobiliary drainage were used. In 10 patients (the fourth group) endoscopic papillosphincterotomy, mechanical lithotripsy, nasobiliary drainage and endobiliary stenting were applied. The best results were achieved in the first group: the smallest duration of the operation--(32.2 +/- 12.6) min, the smallest stationary state duration--(3.3 +/- 1.2) days, the lowest rate of intraoperative complications--2.6%.
