BACKGROUND AND AIMS
To explore the novel treatment of small gastric submucosal tumors (SMTs) originating from the muscularis propria layer (SMT-MPs), we utilized endoscopic band ligation (EBL) with a precut of the covering mucosa.
METHODS
From Jan. 2012 to Dec. 2019, 111 patients with 124 gastric SMT-MPs were treated by precutting EBL. The clinical characteristics, operation duration, postoperative adverse events, and follow-up profiles were retrospectively collected.
RESULTS
A total of 124 tumors from 111 patients were successfully treated by precutting EBL. No adverse events, including perforation and major bleeding, were observed. Furthermore, 93 patients (83.8%) underwent endoscopic surveillance postoperatively, and during the follow-up period, no local recurrence was detected.
CONCLUSIONS
Precutting EBL appears to be a safe and simple method for removing gastric SMT-MPs < 16 mm (mainly indicated for potentially malignant GISTs), but further studies with longer follow-up are needed to assess the radicality of this intervention.
背景与目的
为探索固有肌层起源的小胃黏膜下肿瘤（SMT）的新型治疗方法，我们采用了黏膜预切开的内镜套扎术（EBL）。
方法
回顾性收集了 2012 年 1 月至 2019 年 12 月期间 111 例共 124 个胃固有肌层 SMT 患者的临床特征、手术时间、术后不良事件和随访资料。
结果
124 个肿瘤均采用黏膜预切开 EBL 成功治疗，未出现穿孔和大出血等不良事件。93 例（83.8%）患者术后进行了内镜监测，随访期间未发现局部复发。
结论
黏膜预切开 EBL 似乎是一种安全、简单的方法，适用于直径＜16mm 的胃固有肌层 SMT（主要针对潜在恶性 GISTs），但需要进一步进行长期随访研究以评估该干预的根治性。
