Abstract
BACKGROUND
Several endoscopic treatments for iatrogenic perforations are currently available, with some limitations in terms of size, location, complexity, or cost. Our aims were to introduce a novel technique for closure, using an endoloop and clips, to assess its rate of technical success and post-resection complications.
METHODS
For closure of large perforations (diameter ≥ 10 mm), two similar techniques were implemented, using a single-channel endoscope. An endoloop was deployed through the operating channel or towed by an endoclip alongside the endoscope. Several clips were utilized to fix it on the muscular layer of defect's margins. The defect was closed, by fastening the loop either directly or after being reattached to the mobile hook.
RESULTS
This analysis included eleven patients (72% women, median age 68 years). Eight colorectal, one appendiceal, and two gastric lesions were resected, with a median perforation size of 15 mm. As confirmed by computed tomography, closure of wall defects was achieved successfully in all cases, using a median of 6 clips. Pneumoperitoneum was evacuated in 4 cases. The median hospitalization duration was 4 days, prophylactic antibiotics being prescribed for a median of 7 days. One patient had a small abdominal collection, without requiring drainage, while another presented post-resection bleeding from the mucosal defect.
CONCLUSION
The novel techniques, utilizing a single-channel endoscope, clips, and an endoloop, ensuring an edge-to-edge suture of muscular layer, proved to be safe, reproducible, and easy to implement. They exhibit an excellent technical success rate and a minimal incidence of non-severe complications.
