[Endoscopic purse-string suture for the gastric wall defect after full-thickness resection].

Abstract To evaluate the efficacy of endoscopic purse-string suture (EPSS) with metallic clips and endoloop for the gastric wall defect after postoperative perforation. Clinical data of 25 patients with gastric tumors(1 of gastric adenocarcinoma, 24 of gastric gastrointestinal stromal tumor, GIST) undergoing EPSS in Jiangsu Province People's Hospital and The Second Affiliated Hospital of Nanjing Medical University from January 2013 to May 2014 were retrospectively analyzed. During the procedure, EPSS was performed in 8 cases with perforation after endoscopic submucosal dissection(ESD), and in 17 cases with active perforation after endoscopic full-thickness resection. Twenty-five patients underwent EPSS successfully. The procedure time was 35.0-75.0(49.8±10.1) min. No severe operational and postoperative complications occurred. Tumor resection margin were all negative. Time to withdraw gastrointestinal decompression drainage tube was 1-3(1.3±0.8) d. Postoperative hospital stay was 2-10(4.8±2.1) d and total cost was 10-31(19±0.5) thousand Yuan. One month after the procedure, all the patients received follow-up with no complaint of discomfort, and endoscopy confirmed that all the lesions healed. EPSS with metallic clips and endoloop is effective and safe to close the gastric wall defect after full-thickness resection.
