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

Figure 1 Endoscopic submucosal excavation for treatment of small gastric mesenchymal tumors. A: Small gastric mesenchymal tumor (sGMT) located at the gastric fundus near the cardia; B: Electrocautery markings visible on the sGMT’s surface; C: Submucosal injection around the sGMT; D: Incision of the mucosal surface using a mucosal incision knife (MIK) to expose the tumor; E: Separation of the tumor from its base using a MIK; F: The wound after complete tumor dissection; G: Closure of the wound using titanium clips; H: The completely resected tumor.
