Comparison of endoscopic submucosal dissection and surgical resection for treating gastric subepithelial tumours

AbstractObjective For subepithelial tumours (SETs) of the stomach, surgical resection is the gold standard treatment. With the recent advent of endoscopic resection techniques and devices, endoscopic submucosal dissection (ESD) has been considered as an alternative treatment for SETs. The aim of our study was to evaluate the clinical outcomes of ESD for treating gastric SETs compared with surgical resection. Methods Between January 2006 and September 2014, 55 patients with gastric SETs (13 gastrointestinal stromal tumours (GISTs), 27 leiomyomas, and 15 others) were treated by ESD and 27 patients (19 GISTs, two leiomyomas, and six others) underwent surgical resection. We retrospectively reviewed the therapeutic outcomes, procedure-related complications, post-procedure hospital stays, and medical costs of the two groups. Results The complete resection rate of the ESD group was lower than that of the surgery group (81.8% vs. 100%, p = 0.026). Although the incidence of complications that occurred with ESD was...
