The Use of Novel Over-The-Scope-Clip to Prevent Esophageal Stent Migration

Not Applicable
Not yet recruiting
Conditions
Migration of Implant
Registration Number
NCT05899504
Lead Sponsor
Asian Institute of Gastroenterology, India
Brief Summary

New endoscopic clipping device called the over-the-scope-clip (OTSC) system (Ovesco Endoscopy, Tübingen, Germany) has become available for the closure of perforations, anastomotic leaks, and fistulas. The OTSC system has a stronger closing force than the through-the-scope hemostatic clip. Therefore, some researchers have reported esophageal SEMS fixation with an OTSC to prevent migration.

Detailed Description

Participants requiring esophageal SEMS placement for various indications such as stricture (benign, malignant), leaks All participants who require esophageal SEMS placement. Esophago-gastroscopy will be done to assess the feasibility of SEMS placement.

Participants are randomized into two arms- one arm (interventional) use of OTSC stent fix after esophageal SEMS placement or the other arm (non-interventional) esophageal SEMS is placed.

Participants are followed up for 1 year to observe stent migration rate in both the groups.
