Abstract

Laparoscopic partial gastrectomy of gastric gastrointestinal stromal tumor (GIST) was first introduced in 1999 by Ohgami et al. Later, this procedure has been widely used because of its simplicity and safety. However, a laparoscopic view from the serous surface alone often makes it difficult to accurately localize the tumors that develop in the gastric lumen, thus, it often results in a deeper and wider resection of the gastric wall, which can lead to gastric deformation and gastric outlet obstruction. In addition, there are several reports of positive resection margins and postoperative local recurrence due to lack of knowledge regarding the precise location of the lesion. For resolving these problems, the method of Laparoscopic endoscopic cooperative surgery (LECS) was first establised and applied in 2006 by Naoki Hiki et al. Nowadays, it has not been widely used in Japan but also used around the world. In Vietnam, there is no centers or hospitals that applied this technique so far. We reported 2 cases of gastric submucosal tumor which was successfully treated by LECS technique at Tam Anh Hospital in Ho Chi Minh City to acknowledge the initial experience in performing this technique.
