Various endoscopic defect closure methods following endoscopic full-thickness resection (EFTR) of submucosal tumors have been developed [1] [2]; however, there is no established endoscopic defect closure method that can close a full-thickness defect as reliably as surgical suturing. We developed the reopenable clip-over-line method (ROLM), capable of closure of large mucosal defects and defect closure post-EFTR [3] [4]. Here, we report the use of the ROLM with an omental patch (ROLM-OP), which includes closure of the serosal muscle layer using omental fat ([Video 1]).

Video 1 Gastric full-thickness defect closure using a reopenable-clip over-the-line method with an omental patch.


Quality:

The patient had a 26-mm submucosal tumor on the anterior side of the antrum that was endoscopically resected via full-thickness resection with laparoscopic assistance ([Fig. 1]). The diameter of the full-thickness defect was approximately 30 mm and ROLM-OP was used to achieve complete defect closure. First, a clip with line was placed to grasp the serosal muscle layer and mucosa on the anal side. Next, a reopenable clip with a line through the tooth hole on one side was placed to grasp the serosal muscle layer and the mucosa of the contralateral defect edge. By repeating this procedure, the bilateral defect edges were gradually closed. As the omental fat was endoscopically visible, the reopenable clip could grasp the omental fat, serosal muscle layer, and mucosa. Laparoscopy confirmed that the omental fat was inserted in the closure line, and the full-thickness defect was completely closed using ROLM-OP. A negative laparoscopic leak test result confirmed complete closure, and the procedure was therefore completed without additional suturing.

Fluoroscopy, at 3 days post procedure, revealed no leakage, and the patient was allowed a liquid diet. Endoscopic follow-up 7 days later showed all clips still in place and complete closure of the full-thickness defect. The patient was discharged without experiencing any adverse events. Therefore, ROLM-OP appears to be a novel and feasible technique for full-thickness defect closure.
