No delayed bleeding or peritoneal signs were observed. Perforation occurred in four patients, with all lesions being completely repaired endoscopically.  The complete resection rate was 100 %, the mean tumor size was 10.71 ± 3.45 mm (7 - 18 mm), and the median operative time was 18.5 minutes. All patients were followed for 2 - 6 months.  14 patients with gastric SET-MPs were treated by ESMR-L with AMI between December 2016 and May 2017. The complete resection rate, operation duration, and postoperative complications were collected. €‚This study aimed to evaluate the clinical efficacy, safety, and feasibility of performing endoscopic submucosal resection with a ligation device (ESMR-L) after apical mucosal incision (AMI) for the treatment of gastric subepithelial tumors originating from the muscularis propria (SET-MPs). Zhang, Dingguo Lin, Qiuling Shi, Ruiyue Wang, Lisheng Yao, Jun Tian, Yanhui Ligation-assisted endoscopic submucosal resection with apical mucosal incision to treat gastric subepithelial tumors originating from the muscularis propria.
After the resection of gastrointestinal stromal tumors (GISTs), we did not observe any recurrences during follow-up, indicating that endoscopic full-thickness resection may be an alternative to surgical resection for selected patients. Endoscopic full-thickness resection of gastric subepithelial tumors with the suturing technique described above is feasible and effective. Mean follow-up was 213 days (range, 1 - 1737), and no tumor recurrences were observed. Complete resection was histologically confirmed in 28 of 31 patients (90.3 %).
Perforation occurred in 3 patients (9.6 %), and all perforations could be managed endoscopically. Bleeding occurred in 12 patients (38.7 %) endoscopic hemostasis could be achieved in all cases. Before snare resection, 1 to 3 full-thickness sutures were placed underneath each tumor with a device originally designed for endoscopic anti-reflux therapy. After 31 patients underwent endoscopic full-thickness resection, the data were analyzed retrospectively. The aim of this study was to evaluate the efficacy, safety, and clinical outcome of this resection technique.
