Endoscopic unroofing is effective for diagnosis and therapy of gastric submucosal tumors: A retrospective study including follow-up

Background: Endoscopic unroofing has been established to yield sufficient tissue samples for histological evaluation of gastric submucosal tumors (SMTs). We aimed to evaluate this technique regarding not only its safety and diagnostic accuracy but also its therapeutic efficacy over time. Methods: Demographic data, indication, safety and efficacy (including follow-up) were retrospectively assessed in patients who underwent endoscopic unroofing of a gastric SMT at our department. Results: Between 2003 and 2012 a total of 14 patients (7 male, 7 female, median age 70 years) underwent endoscopic unroofing of 14 SMTs…
