Application of through-the-scope twin clip for defect closure after gastric gastrointestinal stromal tumor transoral super minimally invasive surgery resection

The closure of large or perforated defects has posed a significant challenge in the evolution of endoscopic treatments. The over-the-scope (OTS) clip, once the mainstay for such closures, has certain limitations, such as the necessity for pre-procedure attachment to the endoscope's tip, which may entail additional surgical entries and potentially longer operative times, increasing the risk of complications like postoperative peritonitis [1].
