Adachi A, et al. - In this retrospective study, researchers assessed the effectiveness of mucosal cutting biopsy (MCB) for the histopathological diagnosis of gastric submucosal tumors (SMTs) and established a strategy for the diagnosis of gastric SMTs. For this investigation, MCB and endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) were performed 16 and 31 times for diagnosing gastric SMT between January 2012 and August 2018. The authors concluded that MCB was an effective diagnostic procedure for gastric SMT, particularly in the case of small SMTs located in the middle third of the stomach. In the middle third of the stomach, failures of EUS-FNA were more frequent.
