Primary Outcome Measures

Name	Time	Method
Number of Retrieved lymph nodes	when the pathologist examine the specimen which is within 1 week after operation	Number of Retrieved lymph nodes counted from the dissected lymphofatty tissues of the specimen

Secondary Outcome Measures

Name	Time	Method
amount and duration of drainage	daily, 6AM, until the drain is removed at an expected average of 5 days	the amount of drain (ml)is checked from the closed drain bottle.
length of hospital stay	when the patient leaves the hospital at an an expected average of 9 days	length of hospital stay (day)
satisfaction score	3 months after operation	satisfaction score (from 1 to 5) is evaluated at the out-patient department; (1 = extremely dissatisfied, 2 = dissatisfied, 3 = average, 4 = satisfied, 5 = extremely satisfied)
Operation time	when the dissected specimen is removed from the patient at the average of 78 min for conventional group and 157 min for robot-assisted group	Operation time (minutes) from skin incision to the time point of removing the dissected specimen from the patient
