| Background: We investigated the feasibility of EFTR and defect closure under active traction assistance using a rigid surgical grasper delivered through a novel percutaneous intragastric trocar (PIT) system in cadaveric animal models. Methods: PIT with a single 5mm gastric port was placed using a pull-through placement method of a standard percutaneous gastrostomy tube. Following circumferential mucosal incision, a 5 mm rigid grasper delivered through the port was used to retract tissue of the lesion area towards the gastric lumen, which generated strong traction force during EFTR. The post-EFTR defects were linearized by pulling the defect edge with the grasper in centrifugal direction, which allowed for easy clipping and a serosal layer-to-layer apposition. Results: Full-thickness resection was achieved in 100% out of 3 tentative lesions with traction assistance provided by the rigid surgical forceps delivered through the PIT system. All defects were completely closed with a layer-to-layer apposition accomplished by the rigid surgical forceps. The mean total procedure time of EFTR and defect closure was 41.8 ± 18.7 and 22.0 ± 7.7. The median number of endoclips used for closure was five. Conclusions: PIT may overcome the limitations of current endoscopic procedures including EFTR by allowing strong traction provided by a rigid surgical. |
