Background/Aims: Mucosal cutting biopsy (MCB) is useful for the histopathological diagnosis of gastric subepithelial tumors (SETs). However, there is little information on cases in which MCB did not establish a diagnosis. In the current study, we aimed to investigatethe characteristics of cases in which MCB was unsuccessful. Methods: Cases in which MCB was used to histopathologically diagnose gastric SETs at Kobe University Hospital between August 2012and October 2018 were retrospectively reviewed. Results: Forty-five cases in which MCB was used to diagnose 43 gastric SETs in 43 patients were analyzed. The median tumor sizewas 20 mm (range, 8–50 mm). Pathological examinations resulted in definitive and suspected diagnoses and no diagnosis in 29(gastrointestinal stromal tumor: n=17, leiomyoma: n=7, aberrant pancreas: n=3, others: n=2), 6, and 10 cases, respectively. Failure toexpose the tumor according to retrospective examinations of endoscopic images was significantly associated with no diagnosis. Otherpossible explanations included a less elevated tumor, biopsy of the surrounding field instead of the tumor due to the mobility, and poorendoscope maneuverability due to the tumor being close to the cardia. Conclusions: Clear exposure of gastric SETs during MCB may improve the diagnostic rate of such examinations.
