A Clip-with-Line Traction Suture Method for Closing Mucosal Defects after Endoscopic Submucosal Dissection

Figure 1

(a) Endoscopy showed that a suspicious protruding lesion was identified in the fundus of stomach. (b) A circumferential incision was produced, and a fundic tumor came into sight. (c) The tumor was resected thoroughly, leaving a big perforation. (d) The visceral organ appeared through the perforation. (e) The clip-with-line traction suture was applied. And the mucosal defect was sutured completely. (f) Haematoxylin and eosin (H&E) staining. Amplification factor: 100-fold. (g) Detection of CD34 protein expression by immunohistochemistry. Amplification factor: 100-fold. (h) Detection of CD117 protein expression by immunohistochemistry. Amplification factor: 100-fold. (i) Detection of DOG1 protein expression by immunohistochemistry. Amplification factor: 100-fold.
