Abstract
Background and study aim: Bezoars are compact masses that formed by accumulation of high-fiber diet, undigested food, hair or medications. The majority of bezoars are asymptomatic but they may cause serious symptoms or even life-threatening events such as bleeding, obstruction or perforation. We aimed to investigate the risk factors, endoscopic findings and treatments in upper gastrointestinal bezoars.
Patients and methods: This retrospective study was conducted in three gastroenterology clinics between January 2016 and December 2019. Bezoars were detected in 109 of 15830 endoscopy records (0.68%).
Results: 103 patients (52.4% male) were enrolled in this study. The mean age of the patients was 60.5±11.3 years. The most frequent risk factors were history of gastric surgery (25.2%), diabetes mellitus (21.3%), hypothyroidism (15.5%), trichophagia (5.8%) and anxiety disorders (2.9%), respectively. The most common endoscopic findings were peptic ulcers (34.9%), erosive gastritis/duodenitis (12.6%) and reflux esophagitis (10.6%). While bezoars were most commonly observed in the stomach (84.4%), the majority of them were phytobezoars (92.2%). The mean number of endoscopic interventions for each patient was 1.5 (range, 1-4). Endoscopy was successful in removing bezoars in 85.4%.
Conclusion: These findings indicated that bezoars are more common among patients with history of gastrointestinal surgery, diabetes mellitus or psychiatric disorders. They are closely related to peptic ulcer and reflux esophagitis and they can be successfully treated with endoscopic interventions.
