Summary
This study demonstrates a new endoscopic technique for closing gastric defects after full-thickness resection (EFTR). The "close while dissecting" method using endoclips proved safe and effective for gastric submucosal tumors.
Area of Science:
- Gastroenterology
- Endoscopic Surgery
- Oncology
Background:
- Complete closure of gastric wall defects is crucial after endoscopic full-thickness resection (EFTR).
- A novel endoscopic technique,
- closing while dissecting
- , was developed to address this need.
Purpose of the Study:
- To evaluate the efficacy, safety, and clinical outcomes of the
- interrupted-close during dissection
- technique for gastric defect closure post-EFTR.
Main Methods:
- Retrospective analysis of 27 patients undergoing EFTR between January 2020 and March 2021.
- Gastric defects were closed using the
- interrupted-close during dissection
- technique with endoclips.
- Evaluation of tumor characteristics, en bloc resection rates, and postoperative adverse events.
Main Results:
- Successful en bloc resection of all submucosal tumors (mean diameter 1.3 cm), including GISTs, leiomyomas, and schwannomas.
- No instances of hemorrhage, peritonitis, or delayed perforation.
- All wounds healed within 3 months, with no observed tumor recurrence during a mean 8.5-month follow-up.
Conclusions:
- The
- interrupted-close during dissection
- approach is feasible and safe for EFTR of gastric submucosal tumors.
- This technique facilitates effective closure of gastric wall defects, supporting clinical application.
