Mucosal cutting biopsy technique. (a, b) Using EGD and EUS, it was confirmed that the tumor was an SMT, that the tumor did not protrude outside the gastric wall, and that the tumor was solid, not cystic or vascular. (c) An incision of >=5 mm was made in the superficial mucosa of an elevated area of the tumor with a needle knife, and the tumor was adequately exposed.

MCB was performed with the following method (Figure 1): (1) Using EUS, it was confirmed that the tumor was an SMT, that the tumor did not protrude outside the gastric wall, and that the tumor was solid, not cystic or vascular. (2) Exposures of  5 mm and  10 mm were made in the superficial mucosa of an elevated area of the tumor with a needle knife. (3) The tumor was adequately exposed using FORCED COAG mode. (4) Samples were taken directly using biopsy forceps about 5-7 times. (5) Hemostatic procedures were performed if there was bleeding after the sample was taken.
