Summary

Although Laparoscopic gastrectomy for both early and locally advanced gastric cancer has gained popularity, the use of laparoscopic total gastrectomy for proximal advanced gastric cancer is still limited to some experienced surgeons, because of its technical difficulties in D2 lymph node dissection and anastomoses.

Some retrospective and cohort studies regarding laparoscopic total gastrectomy with lymph node dissection suggested the likelihood of application of laparoscopic surgery for proximal gastric cancer. However, there has been no randomized clinical trial comparing results of laparoscopic total gastrectomy with D2 lymph node dissection with open conventional surgery.

Therefore, we aimed to verify the efficacy of laparoscopic total gastrectomy with D2(D2-10) lymph node dissection, technical and oncologic safety compared with open surgery via multicenter randomized clinical trial.

PROCEDURE

Radical total gastrectomy with D2 (D2 - #10) lymph node dissection by laparoscopic approach

* 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
