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

Figure 1 We treated a case of severe stenosis in the antrum after the endoscopic submucosal dissection procedure. The circumferential extent of the mucosal defect was > 3/4. A: The white arrow shows that the lesion constituted of a semi-circumferential, laterally spreading type 0-IIc early gastric cancer on the anterior wall of the antrum; B: The circumferential extent of the mucosal defect was > 4/5 after the performance of the ESD procedure; C: Three months after the endoscopic submucosal dissection operation, the patient experienced a severe stricture of the gastric antrum. Subsequently, we had to perform a mucosal incision and local steroid injection.
