ObjectiveTo explore the feasibility and effectiveness of application of improved double clamp endoscopy in the perforation after ESD surgery. MethodsA total of 12 cases with gastric submucosal tumor located in intrinsic muscle layer were selected, and the patients who were complicated with the perforation diameter over 2 cm after ESD operation were treated by endoscopic surgery, and improved double clamp endoscopy were used with nylon ring and titanium clip on the perforated line of the purse string suture. The suture success rates are receded so as to evaluate the feasibility of this method. ResultsDouble clamp endoscopy, made by adding a simple pipe into single forceps endoscopy, can repair the postoperative perforation of 2 to 3 cm in diameter after ESD with nylon ring and titanium clips.11 cases were followed up postoperatively for 3 to 6 months, with all endoscopic incisions healed. ConclusionThe improved double clamp endoscopy is easy to operate pouch suturing postoperative complications after ESD, and can be carried out in hospitals with ordinary single forceps endoscopy, proved to be economical, convenient, safe and effective. It can shorten the operation time and repair perforations fast and effectively to avoid a second time surgery and reduce postoperative infection. It has great clinical practical value, and contributes to a more extensive and deeper research in the digestive tract lesions of EMR and ESD technology.
