Intracorporeal Anastomosis in Laparoscopic Gastric Cancer Surgery
Hosogi, Hisahiro,Kanaya, Seiichiro The Korean Gastric Cancer Association 2012 Journal of gastric cancer Vol.12 No.3
Laparoscopic gastrectomy has become widely used as a minimally invasive technique for the treatment of gastric cancer. When it was first introduced, most surgeons preferred a laparoscopic-assisted approach with a minilaparotomy rather than a totally laparoscopic procedure because of the technical challenges of achieving an intracorporeal anastomosis. Recently, with improved skills and instruments, several surgeons have reported the safety and feasibility of a totally laparoscopic gastrectomy with intracorporeal anastomosis. This review describes the recent technical advances in intracorporeal anastomoses using circular and linear staplers that allow for totally laparoscopic distal, total, and proximal gastrectomies. Data that demonstrate advantages in early surgical outcomes of a total laparoscopic method compared to laparoscopic-assisted operations are also discussed.

Laparoscopic distal gastrectomy has become widespread as a treatment for early gastric cancer in eastern Asia, but a standard method for setting the stomach transection line has not been established. Here we report a novel method of setting this line based on anatomical landmarks. At the start of the operation, two anatomical landmarks along the greater curvature of the stomach were marked with ink: the proximal landmark at the avascular area between the last branch of the short gastric artery and the first branch of the left gastroepiploic artery, and the distal landmark at the point of communication between the right and left gastroepiploic arteries. Just before specimen retrieval, the stomach was transected from the center of these two landmarks toward the lesser curvature. Then, about two-third of the stomach was reproducibly resected, and gastroduodenostomy was successfully performed in 26 consecutive cases. This novel method could be used as a standard technique for setting the transection line in laparoscopic distal gastrectomy.

Bangle (Zingiber purpureum) is a tropical ginger that is used as a spice in Southeast Asia. Phenylbutenoid dimers isolated from Bangle have exhibited neurotrophic effects in primary cultured rat cortical neurons and PC12 cells. Furthermore, chronic treatment with phenylbutenoid dimers enhances hippocampal neurogenesis in olfactory bulbectomized mice. In this study, we investigated the effects of Bangle extract on behavior and hippocampal neurogenesis in vivo. SAMP8 mice, which are an established model for accelerated aging, with age-related learning and memory impairments, were given a Bangle-containing diet for 1 month, and subsequent behavioral tests and immunohistochemistry for Ki67, a proliferating cellmarker, were performed. We found that the Bangle-containing diet improved spatial learning and memory deficits in the Morris water maze and significantly increased the numbers of Ki67-positive cells in the dentate gyrus of the SAMP8 mice. In addition, the Bangle extract exhibited a neurotrophin-like activity as indicated by the induction of neurite sprouting in PC12 cells. Our results suggest that Bangle is beneficial for the prevention of age-related progression of cognitive impairment.
