Background
Endoscopic full-thickness resection (EFTR) is a minimally invasive method for en bloc resection of gastrointestinal (GI) lesions originating from the muscularis propria layer. Successful closure of the wall defect is a critical step.
Objective
The aim of this study was to evaluate the feasibility and efficacy of a novel and simplified endoscopic grasp-and-loop (GAL) closure method using an endo-loop assisted with grasping forceps for defect closure.
Methods
From January 2015 to March 2016, 13 patients with submucosal tumors (SMTs) originating from the muscularis propria (MP) layer underwent EFTR and were enrolled in this study. After successful tumor resection, an endo-loop was anchored onto the circumferential margin of the gastric defect with grasping forceps assistance and tightened gently. Patient characteristics, tumor size, en bloc resection, and postoperative complications were evaluated.
Results
Of the 13 lesions in the stomach, two were located in the greater curvature of the mid-upper body, 11 were located in the fundus. The endoscopic GAL closure method was successfully performed after EFTR in all the 13 patients without laparoscopic assistance. The mean procedure time was 43.5 min (range 20–80 min), while the GAL closure procedure took a mean of 9.4 min (range 3–18 min). The mean resected lesion size was 1.5 cm (range 0.5–3.5 cm). Pathological diagnoses of these lesions were 11 gastrointestinal stromal tumors (GISTs) and two leiomyomas. No major adverse events occurred during or after the procedure. All the patients were discharged after a mean time of 2.4 days (range 1–4 days). No residual lesion or tumor recurrence was found during the follow-up period (median, 5 months; range, 1–15 months).
Conclusions
The endoscopic GAL closure method is feasible, effective, and safe for closing the gastric defect after EFTR in patients.
