Abstract

Background and Aims

In the past, endoscopic resection of gastric subepithelial lesions (SELs) was restricted to small lesions confined to the submucosa. Larger and deeper lesions were resected surgically. Recent innovations in endoscopy have yielded multiple techniques for extending the boundaries and providing minimally invasive resection of larger and deeper lesions.

Methods

This article presents the different endoscopic modalities for resecting gastric SELs. The video illustrates, through clinical examples, how to choose the appropriate resection method and provides technical tips for these techniques.

Results

In this case series, we implemented different endoscopic resection modalities on the basis of endoscopic and endosonographic evaluation of the tumor and patient anatomical factors. Successful en bloc resection of gastric SELs was achieved in all patients without adverse events.

Conclusions

Multiple techniques made endoscopic resection of larger and deeper gastric SELs feasible. Successful resection requires familiarity with these techniques' tips and tricks.

胃上皮下病变的内镜切除：技术和提示

背景与目的过去，胃上皮下病变（sel）的内镜切除仅限于粘膜下的小病变。较大和较深的病变通过手术切除。最近在内窥镜方面的创新已经产生了多种技术来扩展边界，并提供更大和更深病变的微创切除。方法介绍不同内镜下切除胃sel的方法。该视频通过临床实例说明了如何选择合适的切除方法，并提供了这些技术的技术提示。结果在本病例系列中，我们根据内镜和超声对肿瘤的评估以及患者的解剖因素实施了不同的内镜切除方式。所有患者均成功切除了胃sel，无不良事件发生。结论多种技术使内镜下大、深胃sel切除术成为可能。成功切除需要熟悉这些技巧和技巧。

期刊介绍： VideoGIE, an official video journal of the American Society for Gastrointestinal Endoscopy, is an Open Access, online-only journal to serve patients with digestive diseases. VideoGIE publishes original, single-blinded peer-reviewed video case reports and case series of endoscopic procedures used in the study, diagnosis, and treatment of digestive diseases. Videos demonstrate use of endoscopic systems, devices, and techniques; report outcomes of endoscopic interventions; and educate physicians and patients about gastrointestinal endoscopy. VideoGIE serves the educational needs of endoscopists in training as well as advanced endoscopists, endoscopy staff and industry, and patients. VideoGIE brings video commentaries from experts, legends, committees, and leadership of the society. Careful adherence to submission guidelines will avoid unnecessary delays, as incomplete submissions may be returned to the authors before initiation of the peer review process.
