Background: This prospective study was designed to evaluate the safety and efficacy of submucosal tunneling endoscopic resection (STER) for small (≤3 cm) upper gastrointestinal (GI) subepithelial tumors (SETs) originating from the muscularis propria (MP) layer.
Methods: Between August 2011 and February 2013, a total of 85 patients with upper GI SETs originating from the MP layer were treated with STER. The key steps were as follows: (1) locating the tumor by injection of methylene blue or indigo carmine and then creating a submucosal tunnel from 5 cm above the tumor between the submucosal and muscular layers; (2) resecting the tumor by endoscopic resection techniques; (3) closing the mucosal incision site with several clips after the tumor is removed.
Background And Aims: The aim of this prospective study was to evaluate the feasibility of submucosal tunnelling endoscopic resection of esophageal tumours originating from the muscularis propria layer.
Methods: Fifteen patients with esophageal submucosal tumours originating from the muscularis propria layer underwent submucosal tunnelling endoscopic resection between August 2011 and February 2012. The key steps were: (1) creating a submucosal tunnel from 5 cm above the tumour between the submucosal and muscular layers with a hook knife or hybrid knife; (2) dissecting the tumour by the technique of endoscopic submucosal dissection; (3) closing the mucosal incision site with clips after the tumour was removed.
Background/aims: Capsule endoscopy (CE) reaches the cecum in about 80% of cases. Decreasing the gastric transit time (GTT) may increase the complete examination rate (CER).
Methodology: Patients (n=177) were prospectively randomized into 2 groups: the control group (n=88) and the intramuscular injection with metoclopramide (IIM) group (n=89).
