Primary Outcome Measures:
  • noncompliance rate [ Time Frame: postoperative 1 week ]
    A Case will be designated as "noncompliant" when there are more than one missing lymph node station according to the guidelines of "The Japanese Research Society for Gastric Cancer" (JRSGC) lymph node grouping


Secondary Outcome Measures:
  • Postoperative surgical complications [ Time Frame: postoperative 1 day, 1 week, 1 months, 3 months, 6 months, 12 months ]
    Major and minor, and short term and long term complications related with surgery will be monitored and recorded according to classification of Accordion Severity Classification of Postoperative Complications; Expanded Classification.

  • operating time [ Time Frame: operation day ]
    From skin incision to wound closure

  • time to first flatus [ Time Frame: postoperative 1 week ]
    the day when a patient relieve gastrointestinal gas

  • number of retrieved lymph nodes [ Time Frame: postoperative 1 week ]
  • number of retrieved lymph nodes at each stations [ Time Frame: postoperative 1 week ]
  • proximal resection margin [ Time Frame: postoperative 1 week ]
  • distal resection margin, [ Time Frame: postoperative 1 week ]
  • unanimity rate of 3 randomly assigned laparoscopic gastric cancer surgeons [ Time Frame: postoperative 3 months ]
    Three randomly assigned laparoscopic gastric cancer surgeons would evaluate the uneditted video and photoes and validate the lymph node dissection according to each stations.When the three surgeons agree that D2 lymph node dissection was performed, it is considered as unanimity.

  • 3-year disease free survival [ Time Frame: postoperative 3 years ]

Enrollment: 204
Study Start Date: June 2010
Estimated Study Completion Date: December 2016
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)

Other Name: LADG

Detailed Description:
To test oncological feasibility, compliance of nodal dissection was selected as a primary end point. When there are more than two missing nodal station(no lymph nodes in dissected area), it is defined as a non-compliant nodal dissection. Other secondary outcomes will be supplementary to evaluate feasibility of D2 dissection.
