Trial for Application of Laparoscopic Total Gastrectomy With Lymph Node Dissection for Gastric Cancer (KLASS-06)

"* Total gastrectomy with D2(D2-10) lymph node dissection by laparoscopic approach~* The number of trocars is 6 or less~* Roux-en-Y esophagojejunostomy with any stapling method~* Enough(negative) margin from tumor~* LN station #1, 2, 3, 4d, 4sb, 5, 6, 7, 8a, 9, (10), 11p, 11d, 12a should be examined~* Washing cytology~* Frozen biopsy for surgical margin at surgeons discretion~* Complete omentectomy for grossly serosa-involved tumor~* Combined organ resection only in cholecystectomy and splenectomy~* Indwelling nasogastric tube and drainage catheter at surgeons discretion~* D2 lymphadenectomy should be performed : dissection of LN stations No.4d, 4sb, 4sa, 2, 10 (splenic hilar LN can be left according to the clinical stage), 6, 5, 12a, 8a, 9, 7, 1, 3, 11p, 11d with prevention of pancreatic injury during suprapancreatic dissection"
