Core Tip

Core Tip: Forty patients with benign bilioenteric anastomotic stricture received percutaneous transhepatic cholangioscopy (PTCS)-assisted procedures, including stricture dilation/recanalization and stone therapy. The cumulative anastomotic patency due to a PTCS catheter across the anastomosis placed 6 months ago is superior to initial anastomotic patency (balloon dilation alone), i.e., 74.3% and 69.7% vs 58.1% and 41.9% at 1 and 2 years, respectively, with a treatment success rate of 90.6% (29/32). Technical success for stone therapy, including 20 patients with electrohydraulic or laser lithotripsy, was achieved in 34 (94.4%) patients. PTCS-assisted procedures are efficacious, especially for the treatment of intrahepatic stones. PTCS catheter placement across the anastomosis after stricture dilation can improve the anastomotic patency.
