Endoscopic resection of gastrointestinal stromal tumors

Surgical resection is regarded as the main modality for the treatment of gastrointestinal stromal tumors (GISTs). With the advancement of endoscopic techniques and the introduction of super minimally invasive surgery (SMIS), endoscopic resection has been an alternative option to surgery. Recently, various endoscopic resection techniques have been used for the treatment of GISTs, including endoscopic submucosal dissection (ESD), endoscopic submucosal excavation (ESE), endoscopic full‐thickness resection (EFR), submucosal tunneling endoscopic resection (STER), and laparoscopic and endoscopic cooperative surgery (LECS). Studies on the safety and efficacy of the endoscopic treatment of GISTs have emerged in recent years. Endoscopic resection techniques have demonstrated to be effective and safe for the treatment of GISTs. However, there is currently no consensus on the optimal follow‐up strategy and the appropriate cut‐off value of tumor size for endoscopic resection. In this review we discussed the indications, preoperative preparation, procedures, efficacy, safety, postoperative evaluation, follow‐up, and perspectives of endoscopic resection modalities for GISTs.
