Detachable over-the-scope clip for colon defects in the trans intestinal natural orifice transluminal endoscopic cholecystolithotomy: A case report.

Background: Secure transluminal closure remains a fundamental barrier to endoscopic surgery. It has been reported that through-the-scope clips were used to secure the incision of the gallbladder during natural orifice transluminal endoscopic cholecystolithotomy and were left in the body post-operation. The over-the-scope clip (OTSC) is favored for its rapid deployment and strong anchoring capabilities. Nevertheless, OTSCs are difficult to remove once implanted. The Senscure Biotechnology in China has developed a detachable over-the-scope clip (D-OTSC) for this purpose. Here, we utilized the D-OTSC to successfully close a full-thickness sigmoid defect exceeding 1 cm in diameter. Subsequently, the clip was completely removed postoperatively, yielding favorable clinical outcomes.

Case summary: We present the case of a 51-year-old female patient who underwent natural orifice transluminal endoscopic cholecystolithotomy. The sigmoid incision was closed using a D-OTSC. Postoperative recovery was uneventful, with no abdominal infection or bleeding. The D-OTSC was subsequently removed via enteroscopy in the outpatient department one month later.

Conclusion: The utilization of D-OTSC presents a viable option for closing colonic mucosal incisions ranging from 1 cm to 2 cm.
