Efficacy and safety of endoscopic submucosal dissection for gastric tube cancer: A multicenter retrospective study

Figure 1 A case of subcutaneous abscess formation after perforation during endoscopic submucosal dissection for gastric tube cancer. A: Gastric tube cancer located at the anterior wall of gastric body; B: Marking dots were placed around the lesion, and endoscopic submucosal dissection (ESD) was performed as usual; C: Perforation occurred during ESD; D: Perforation was sealed immediately with 4 endoclips; E: Redness of the skin in the precordial area, 20 d after ESD; F: Computed tomography performed 20 d after ESD. A subcutaneous abscess (yellow arrow) had formed around the gastric tube of the antethoracic reconstruction route (orange arrow).

Figure 2 Overall survival curve after endoscopic submucosal dissection for gastric tube cancer. The survival rate at 5 year was 59.5%. ESD: Endoscopic submucosal dissection.
