Endoscopic “calabash” ligation and resection for small gastric mesenchymal tumors

Figure 2 Endoscopic “calabash” ligation and resection for treatment of small gastric mesenchymal tumors. A: Electrocoagulation imprints visible on the small gastric mesenchymal tumor (sGMT)’s surface; B: Submucosal injection around the sGMT; C: Incision of the mucosa on the surface of the sGMT using the tip of an electrosurgical snare; D: Protrusion of the tumor after negative pressure suction; E: First nylon loop ligating of the tumor base; F: Formation of the “calabash” shape after a second nylon loop, and resection of the tumor situated in the superior portion of the “calabash” utilizing the electrosurgical snare; G: Intact lower part of the “calabash” without perforation, with reinforcement ligation using a nylon loop; H: Completely resected tumor specimen.
