BACKGROUND AND STUDY AIMS: Effective tissue traction is crucial for gastric endoscopic full-thickness resection (EFTR) to ensure a clear visual field for the dissection site. We aimed to evaluate the effectiveness of internal traction using a novel clip-with-spring device in assisting gastric EFTR.
PATIENTS AND METHODS: Twenty-six patients with gastric subepithelial lesions from the muscularis propria were enrolled for internal traction-assisted EFTR (IT-EFTR) and 26 patients for non-assisted EFTR (NA-EFTR) were enrolled as controls.
RESULTS: Average tumor size was 1.5 ± 0.4 cm. All EFTRs were completed successfully with an average total procedure time of 62.4 ± 43.0 minutes and perforation time of 37.2 ± 29.9 minutes. En bloc resection was achieved in 50 patients (96.2%). IT-EFTR significantly improved serosa exposure score (3.4 ± 0.9 vs. 1.9 ± 0.7, P <0.001) and shortened total procedure time (33.0 ± 21.8 vs. 91.8 ± 38.6 min, P <0.001) and perforation time (19.0 ± 18.8 vs. 55.5 ± 27.8 min, P <0.001) compared with NA-EFTR. There were no significant differences in complication rates between the two groups. However, visual analogue score after the procedure was significantly lower (4.2 ± 1.0 vs. 4.7 ± 0.7, P =0.037) and postoperative hospital stay (3.7 ± 2.1 vs. 4.8 ± 1.3, P =0.038) was significantly shorter in the IT-ERTR group than in the NA-EFTR group.
CONCLUSIONS: Internal traction using the novel clip-with-spring device could significantly improve safety and efficacy of gastric EFTR in the distal stomach.
