Abstract

Covered self‑expandable metallic stents (CSEMS) may provide palliative drainage for unresectable distal malignant biliary strictures. Laser‑cut CSEMS allows easy positioning due to its characteristic of minimal stent shortening. Endoscopic stent removal is sometimes recommended for recurrent biliary obstruction (RBO). However, there are no previous reports of endoscopic removal of laser‑cut CSEMS. The current study presents data from 6 patients who were placed a laser‑cut CSEMS for unresectable distal malignant biliary strictures, and later endoscopic stent removal was attempted for RBO at the present institute. The duration of stent placement, the procedural success rate, the procedural duration, and accidental complications were evaluated. The mean duration of stent placement was 156±37.9 days (range, 117‑205). The procedural success rate was 100%. The mean procedural duration was 11.8±7.5 min (range, 5‑24). No complications were reported. Laser‑cut CSEMS were safely removed from all patients. The present case report is the first to demonstrate that Endoscopic stent removal of laser‑cut CSEMS was safely performed.
