Transfistula cholangioscopy: clarification of the diagnosis and antegrade removal of residual bile duct stones

Aim. To demonstrate our own experience of performing transfistula cholangioscopy and removing bile duct stones. Materials Methods. From 2017 to 2019, 230 patients with functioning external biliary drains underwent antegrade cholangioscopy. Preliminary dilatation straightening the fistulous tract were required in 37 patients. Results. Bile stones detected 158 (68.7%) During cholangioscopy, removed from all In 68 cases large choledocholithiasis, it was necessary perform contact lithotripsy. this end, staged treatment two hospitalizations five cases. Adequate transfistular access ducts formed during first hospital stay; second, after hardening walls, removed. The overall complication rate 3.8%, including grade III–IV complications (1.9%) according Clavien–Dindo classification. Mortality 0.4%. Conclusion. Transfistula increases reliability stone detection ducts, permits them without mandatory dissection major duodenal papilla, creates favorable conditions for a more accurate assessment its functional state. When unresolved diseases are placed specialized medical center, they can be provided high-quality care. Additionally, rational use highly effective methods endobiliary diagnosis treatment.
