Core Tip

Core tip: This was a prospective clinical diagnostic trial seeking to evaluate the efficacy of endoscopic ultrasound-guided cutting of holes and deep biopsy for the diagnosis of gastric infiltrative tumors and gastrointestinal submucosal tumors using a novel vertical diathermic loop. This new technique was proved to be a safe, technically feasible and more accurate option for patients with gastric infiltrative tumors or gastrointestinal submucosal tumors.
