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/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 15.8610.94mm, 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 10.447.78mm, 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.
