Percutaneous transhepatic cholangioscopy (PTCS) is effective for treating postoperative benign bilioenteric strictures and biliary stones.

• Initial anastomotic patency rates are 58.1% at 1 year and 41.9% at 2 years.
• Cumulative patency rates drop to 34.8% after 7 years but treatment success is high at 90.6%.

These findings suggest PTCS should be a go-to for managing strictures, enhancing patient outcomes with minimal complications.

• Technical success rates were 100% for dilation and 94.5% for stone therapy.
• One case of manageable bleeding was reported.
