Abstract:
The results of studying of the treatment effectiveness in 30 patients with residual choledocholithiasis (RC) were generalized. In 131 (23.8%) of patients simultaneously with endoscopic papillosphincterotomy (EPST) various endobiliary manipulations on biliary ducts were conducted, in 21 (16.2%) of them--nasobiliary drainage, in 14 (10.8%)--mechanical lithotripsy, in 6 (4.5%)--lithotripsy plus nasobiliary drainage. Great significance in RC diagnosis have the methods of direct contrasting of biliary ducts. The authors characterize the partial, subtotal and total EPST according to the length of major duodenal papilla incision. After papillosphincterotomy in 97 (75%) of patients the concrements were mechanically removed with maximal diameter 2.5 cm. In 10.8% of patients complications occurred. All of the patients are alive.
