Novel method to prevent gastric antral strictures after endoscopic submucosal dissection: Using triamcinolone

Figure 4 We performed our proposed new method during endoscopic submucosal dissection at gastric antrum (Case 2). A: Endoscopic imaging showed that the lesion constituted a one-third circumferential, laterally spreading type 0-IIc early gastric cancer on the anterior wall of the antrum (white arrow); B: A three-fourths circumferential mucosa in the antrum was removed by standard endoscopic submucosal dissection (ESD) procedure; C: The day after the ESD, there was abundant vascularization in the ESD ulcer; D: Two weeks after the ESD operation, there was more granulation tissue than usual in the ESD ulcer; E: Three months after the ESD operation, there were no strictures concomitant with the healing process near the ESD ulcer.
