Background

We previously treated small gastric submucosal tumors originating from the muscularis propria layer by precutting endoscopic band ligation but lacked precise pathological results. Then, precutting endoscopic band ligation was modified by additional snare resection after ligation to obtain tumor specimens, termed precutting endoscopic band ligation-assisted resection.

Aims

In this study, we aimed to explore the safety, feasibility, and efficacy of precutting endoscopic band ligation-assisted resection.

Methods

From 2021 to 2022, a total of 16 consecutive patients underwent precutting endoscopic band ligation-assisted resection to treat small gastric submucosal tumors originating from the muscularis propria. The clinical demography, perioperative data, and follow-up outcomes were retrospectively collected.

Results

With a mean operative time of 21.3 min, all lesions were successfully and completely resected, and no severe adverse events or local recurrences occurred postoperatively. More importantly, en bloc and R0 resection were achieved in all 16 patients.

Conclusion

Precutting endoscopic band ligation-assisted resection is a safe, effective, and time-saving endoscopic technique for managing gastric small gastric submucosal tumors originating from the muscularis propria for both diagnosis and eradication.

Graphical Abstract

背景

我们以前通过预切割内镜带结扎术治疗起源于固有肌层的小型胃粘膜下肿瘤，但缺乏精确的病理结果。然后，对预切内镜带状结扎进行改进，在结扎后额外切除圈套器以获得肿瘤标本，称为预切内镜带状结扎辅助切除术。

目标

在本研究中，我们旨在探讨预切内镜带状结扎辅助切除术的安全性、可行性和有效性。

方法

2021年至2022年，连续16例患者接受预切内镜带结扎辅助切除术，治疗起源于固有肌层的胃粘膜下小肿瘤。回顾性收集临床人口统计学、围手术期数据和随访结果。

结果

平均手术时间21.3分钟，所有病灶均成功完整切除，术后未发生严重不良事件或局部复发。更重要的是，所有16名患者均实现了整块切除和R0切除。

结论

预切内镜带结扎辅助切除术是一种安全、有效、省时的内镜技术，用于治疗起源于固有肌层的胃小胃粘膜下肿瘤，可实现诊断和根除。
