| [Objective] In gastric EFTR, it is crucial to develop robust and technically easy closure method that enables seromuscular inverted closure. Here, we evaluated the efficacy of our-developed dual grasping forceps-assisted over-the-scope clip inverted closure (DG-OTSC) after gastric EFTR. [Methods] The subjects included eight cases with gastric GIST of 3 cm or less, who underwent EFTR under laparoscopic assist between December 2022 and March 2024 (Ethics Approval No.2021-167). The following procedural steps were performed: 1. Dual TechGrasper forceps were inserted into the gastroscope's dual channels mounted with an OTSC. 2. One forceps was used to grasp the seromuscular layer on one defect side. 3. The other was opened to grasp the contralateral seromuscular layer. 4. Both grasping forceps were pulled into the OTSC cap, and then an OTSC was deployed. The primary outcome was complete inverted closure confirmed by laparoscopy. [Results] Complete inverted closure was achieved in all cases, with an average closure time of 34 minutes (range: 19-47). Sustained closure on POD7 was successful in all cases, and one bleeding case was observed. Closure time was significantly shorter in DG-OTSC group than conventional group using TwinGrasper. [Conclusion] Cost-effective DG-OTSC may be a convenient and reliable option for achieving seromuscular inverted closure. |
