Risk factors for recurrence of artificial gastric ulcers after endoscopic submucosal dissection.
It has been reported previously that artificial gastric ulcers caused by endoscopic submucosal dissection (ESD) would heal within 8 weeks, irrespective of their size and location. The aim of this retrospective study was to describe long-term outcomes of gastric ESD ulcers. Check-up of ulcers was performed by periodic endoscopy. The rate of ESD ulcer recurrence and clinicopathological factors that may relate to recurrence were assessed. During the median observation period of 33 months, a benign ulcer recurrence occurred in 10 lesions in 10 patients (2.1%). Univariate analysis showed that Helicobacter pylori infection and presence of pathological ulcer findings within the ESD specimen were significantly related to the risk of ESD ulcer recurrence. Although the frequency is low, there is a possibility of ESD ulcer recurrence in patients with H. pylori infection and in patients who undergo ESD for a lesion with ulceration.
