Abstract
Laparoscopic D2 radical surgery for gastric cancer is minimally invasive but complex. In this path: (1) Repeated operation of lesser curvature side; (2) The gastrohepatic ligament is relatively fixed. Hence, it is not easy to expose the suprapancreatic area; and (3) It is not easy to dissect No. 1, 12 lymph nodes. This area may not be sufficiently cleaned or surrounding vessels may be injured during a resection. So it is critical to choose position fixing, and a clear, fast and convenient operation path. The author, based on his experience, has established a set of procedural steps called "Gao's double-way", lesser omentum approach and traditional greater omentum approach, which are described in detail in this article. The path of this first approach is described as a "W" type of dissection. The second way is the traditional greater omentum approach, whose path is described as a "M" type of dissection. This will enable laparoscopic surgeons to select a suitable path. This new approach not only simplifies the surgery but also provides more space for the subsequent operation, thereby making the surgery more simple, safe and easy.
