研究目的:

本研究旨在通过一项多中心前瞻性、随机、对照研究,评估“All In One”一次性使用电圈套切开刀在胃上皮下肿瘤超级微创切除术(以EFTR/ESD为代表)中应用的有效性与安全性。 (1)评估该一体化器械在手术中的技术成功率与操作效率,核心指标包括:病灶整块切除率、R0切除率以及关键的手术时间(特别关注因器械一体化而节省的器械交换与操作时间)。 (2)系统评价其围手术期安全性,记录器械相关不良事件及术后并发症(如出血、穿孔、感染等)的发生率。 (3)初步探索应用该器械对缩短学习曲线、降低操作难度的潜在价值。 (4)分析其对手术总耗材成本的潜在影响。  

Objectives of Study:

This study aims to evaluate the efficacy and safety of the "All In One" single-use electric loop resectoscope in super-minimally invasive resection of submucosal tumours of the stomach (represented by EFTR/ESD) through a multicentre, prospective, randomised, controlled trial. (1) To evaluate the technical success rate and procedural efficiency of this integrated device during surgery, with core metrics including: complete lesion resection rate, R0 resection rate, and key procedural timings (particularly focusing on time saved through instrument integration, eliminating instrument changes and operational delays). (2) Systematically evaluate perioperative safety by recording the incidence of device-related adverse events and postoperative complications (e.g., haemorrhage, perforation, infection). (3) Preliminary exploration of the device's potential value in shortening the learning curve and reducing procedural difficulty. (4) Analyse its potential impact on total surgical consumables costs.
