Quality Control Study of Laparoscopic Sentinel Node Biopsy in Early Gastric Cancer

Quality Control Study for Multicenter Phase III Trial of Laparoscopic Sentinel Node Biopsy and Stomach Preserving Surgery in Early Gastric Cancer

Laparoscopic sentinel lymph node biopsy and stomach preserving surgery in ealry gastric cancer is less invasive method which can increase quality of life. Multicenter phase III trial is requred to validate this method. In this study all items which are necessary for laparoscopic sentinel lymph node biopsy are identified according to checklist and evaluated the performance completement.
