Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
While the advantage of laparoscopic distal gastrectomy over open distal gastrectomy for not only early gastric cancer (EGC) but also locally advanced gastric cancer (AGC) had been proven, the use of laparoscopic total gastrectomy (LTG) for GC, particularly for AGC, has not been widely accepted due to technical challenges with lymphadenectomy at the distal pancreas and the splenic hilum as well as the complexity of the esophago-jejunal reconstruction. Recently, there has been advancement in laparoscopic techniques and improved surgical experience, a standard procedure of LTG has been established, leading to increase utilization of LTG, especially for EGC. Two large RCTs, KLASS-03 in Korea and CLASS-02 in China, provided good evidence for the advantages of LTG for EGC. However, for AGC, some prior studies have demonstrated the safety of LTG compared to OTG but lacked significant data for survival. Until now, there have been no completed RCTs to determine the short- and long-term outcomes of LTG for AGC.
In the research center, LTG has been accepted as a standard procedure for EGC since 2008 and for AGC since 2013. In Vietnam and other low-to-middle-income countries, most GC was diagnosed in an advanced stage. It is needed to have evidence of the feasibility, safety, and oncological results of LTG for locally advanced GC. Investigators performed this study to compare the technical feasibility, short- and long-term outcomes of LTG versus OTG for stage T2-4a GC.

Laparoscopic total gastrectomy
5 trocars were used. The gastrocolic ligament was divided along the border of the transverse colon. ligating the left gastroepiploic vessels to remove group 4sb.
The right gastroepiploic vein was divided and right gastroepiploic and inferior pyloric artery were transected at their origin from the gastroduodenal artery to dissect group 6.
The dissection was continued along the hepatoduodenal ligament to removed group 5 and group 12a and along the common hepatic artery to remove group 8a and along the celiac axis to remove group 9.
The left gastric vein was divided and then the left gastric artery was vascularized to remove group 7.
The dissection was continued upward along the splenic artery and its branches to remove group 11p,d and/or along the splenic hilum to remove group 10.
The dissection was then conducted the right and left of the esophago-gastric junction to remove group 1,2.
As a general rule, Roux en Y method was used for esophagoo-jejunal reconstruction for all cases
Laparoscopic gastrectomy
Gastrectomy with laparoscopic approach
Open total gastrectomy
An incision of 15\~20 cm length is made in the abdominal midline . Standard total gastrectomy and omentectomy will be performed with D2 lymph node dissection (around common hepatic artery, celiac artery, along splenic artery, proper hepatic artery, and/or the splenic hilum) . Roux-en Y esophagojejunal anastomosis is performed for reconstruction.
