BACKGROUND/AIMS: With technical and instrumental advances, the endoscopic removal of bezoars is now more common than conventional surgical removal. We investigated the clinical outcomes in a patient cohort with gastrointestinal bezoars removed using different treatment modalities. METHODS: Between June 1989 and March 2012, 93 patients with gastrointestinal bezoars underwent endoscopic or surgical procedures at the Asan Medical Center. These patients were divided into endoscopic (n=39) and surgical (n=54) treatment groups in accordance with the initial treatment modality. The clinical feature and outcomes of these two groups were analyzed retrospectively. RESULTS: The median follow-up period was 13 months (interquartile range [IQR], 0 to 77 months) in 93 patients with a median age of 60 years (IQR, 50 to 73 years). Among the initial symptoms, abdominal pain was the most common chief complaint (72.1%). The bezoars were commonly located in the stomach (82.1%) in the endoscopic treatment group and in the small bowel (66.7%) in the surgical treatment group. The success rates of endoscopic and surgical treatment were 89.7% and 98.1%, and the complication rates were 12.8% and 33.3%, respectively. CONCLUSIONS: Endoscopic removal of a gastrointestinal bezoar is an effective treatment modality; however, surgical removal is needed in some cases.
