 We report two cases of gastrointestinal stromal tumor near the ligament of Treitz, which were resected by complete laparoscopic surgery. Case1: A 73-year-old man presented with melena, and a tumor measuring 65mm in size was discovered in the proximal jejunum or mesentery by CT. We performed the operation using SILS+1 ports, and found a jejunal tumor measuring 60mm in size 2 cm from the ligament of Treitz. We resected the tumor and reconstructed the intestine by intracorporeal functional end-to-end anastomosis aided by the addition of another port parallel to the third part of the duodenum. Case2: A 74-year-old man presented with a cough, and a calcified tumor was discovered in proximal jejunum by CT. We performed the operation using 4 ports, and found a jejunal tumor measuring 40mm in size, which was 0.5cm from the ligament of Treitz. We resected the tumor and reconstructed the intestine by intracorporeal functional end-to-end anastomosis aided by the addition of another port parallel to the third part of the duodenum. Both tumors were GIST. Through these two cases, we optimized the location of the ports in order to carry out the procedure completely through laparoscopic surgery.
