    Abstract:
    BACKGROUND AND STUDY AIMS: Endoscopic submucosal excavation (ESE) and endoscopic full-thickness resection (EFTR) are common endoscopic minimally invasive methods for treatment of gastric submucosal tumors (SMTs). However, it is sometimes difficult to expose the tumor optimally. This study aimed to explore the safety and effectiveness of tumor traction using orthodontic rubber band (ORB) combined with clips to assist ESE and EFTR of gastric SMTs. PATIENTS AND METHODS: The data of patients with gastric SMTs who underwent ESE or EFR at the Endoscopy Center of the 900th Hospital of PLA from January 2021 to May 2022 were retrospectively analyzed. Baseline characteristics and clinical outcomes, including operation time and postoperative adverse events, were compared between patients receiving ORB-ESE/EFTR and conventional ESE/EFTR. RESULTS: A total of 52 patients were enrolled: 16 patients who underwent ORB-ESE /EFTR and 36 patients who underwent conventional ESE/EFTR. Median procedure time was significantly shorter in the ORB-ESE/EFTR group than in the conventional ESE/EFTR group (32 [IQR, 23.8, 38.0] minutes vs. 39.0 [IQR, 34.6-67.3] minutes, P = 0.002). Baseline characteristics, en bloc resection rate, incidence of postoperative adverse events, and postoperative pathology results were comparable between the two groups (P > 0.05). CONCLUSION: Use of ORB with clips-assisted traction during ESE/EFTR of gastric SMT can shorten the surgical time. Further large prospective studies are needed to confirm the findings of this study.
