Analysis of the Clinical Characteristics and Endoscopic Features of Phytobezoar-Induced Ulcers and Gastric Ulcers: A Single-Center Retrospective Study in China.

BACKGROUND Bezoar-induced ulcers are the most common complication of bezoars, and they may cause severe complications such as gastrointestinal perforation and bleeding. We analyzed the clinical characteristics and endoscopic features of bezoar-induced ulcers and gastric ulcers, to make a diagnosis and administer appropriate treatment for bezoars and bezoar-induced ulcers as soon as possible to reduce the incidence of complications. MATERIAL AND METHODS Records from 163 patients with bezoar-induced ulcers (Group A) and 155 patients with gastric ulcers (Group B) from 2014-2025 were collected in the study. We compared demographic and clinical characteristics, endoscopic data, treatments, and complications between the 2 groups. RESULTS Bezoar-induced ulcers were more common in women and were more prevalent in the autumn and winter seasons. Gastric ulcers were more common in men. Abdominal pain was more common in Group A (92.0% vs 35.5%). The mean size of the bezoar-induced ulcers was 15.86±10.94 mm, and they were more common in the gastric angle. Most patients had multiple bezoar-induced ulcers but they were often superficial enough to be healed with a short treatment course. The mean length of the gastric ulcers was 10.44±7.78 mm, and they were more common in the gastric sinus. These ulcers were mostly solitary but were difficult to heal, requiring a long treatment course. CONCLUSIONS Bezoar-induced ulcers and gastric ulcers can be distinguished based on different demographic and clinical characteristics and endoscopic features. Bezoar-induced ulcers are mostly multiple and superficial and can be healed with a short course of treatment.
