Abstract

Background: Although artificial ulcers generally heal faster than Helicobacter pylori-related or nonsteroidal anti-inflammatory drug-related peptic ulcers, endoscopic submucosal dissection (ESD)-induced gastric ulcers are usually treated with a proton pump inhibitor (PPI) for 4-8 weeks. The effect of oral administration of a PPI for 1 week on ESD-induced gastric ulcers has not yet been evaluated. In the present study, we evaluated the efficacy of oral PPI for 1 week in patients with ESD-induced ulcers. Methods: We selected 45 patients who underwent ESD for gastric mucosal tumors between June 2005 and July 2006 at Toyama University Hospital, and who met our inclusion criteria. All patients received omeprazole intravenously for 2 days after ESD and then orally for 1 week to prevent bleeding. Twenty two patients received no further omeprazole therapy (1-week group) and the rest received omeprazole orally for 7 more weeks (8-week group). Follow-up endoscopy was performed at 1 day, 4 weeks, and 8 weeks after ESD. We compared the ulcer healing rates between both groups. Results: There were no significant differences between the groups in the ulcer-healing rate, because ulcers healed in 22 (96%) and 20 (91%) patients from the 8-week and 1-week groups, respectively. Conclusions: In our study, oral administration of omeprazole for 1 week was sufficient to achieve healing of ESD-induced artificial gastric ulcers. A larger prospective trial will be required to confirm these findings.
