Summary
Brief summary (as posted)
There are more than 75% of patients with gastric cancer who are diagnosed in advanced stage in Vietnam, most of cases in T4a. The purpose of this study was to compare short- and long- term outcomes of open and laparoscopic distal gastrectomy for gastric adenocarcinoma in surgical T4A stage.

- Open distal gastrectomy
- description
- An incision of 15\~20 cm length is made in the abdominal midline . Standard distal gastrectomy and omentectomy will be performed with D2 lymph node dissection (around common hepatic artery, celiac artery, proximal part of splenic artery, proper hepatic artery) . As a general rule, Billroth I, Billroth II or Roux en Y method was used for gastric reconstruction.
- label
- Laparoscopic distal gastrectomy
- description
- 5 trocar 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 the right gastroepiploic and the inferior pyloric artery were vascularized and cut at their origin from the gastroduodenal artery, just above the pancreatic head, 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 prepared and separately divided and then the left gastric artery was vascularized to remove group 7. The dissection was continued upward along the proximal branches of splenic vessels to remove group 11p and along the lesser curvature to remove group 1,3. As a general rule, Billroth I, Billroth II or Roux en Y method was used for gastric reconstruction.
