title: [Laparoscopic abdominoperineal resection for low rectal cancer].
abstract: OBJECTIVE
  To assess the advantage and disadvantage of laparoscopic abdomino-perineal resection and open abdominoperineal resection for low rectal cancer.
  
  
  METHODS
  Patients with low rectal cancer, collected from July 2003 to April 2006, were randomly divided into laparoscopic abdominoperineal resection group (37 cases) and open abdominoperineal resection group (37 cases). Operation time, number of lymph node removed, intra-operative blood loss, time to pass flatus, time to ambulate, time to discharge, complications, early recurrence, and economical cost were compared between the 2 groups.
  
  
  RESULTS
  All patients were performed successfully. For the first 10 patients, operation time of laparoscopic group was significantly longer than that of open group, but there was no significant difference between the 2 groups. Intra-operative blood loss of laparoscopic group was significantly less than that of open group, but it was reverse for the first 10 patients. There was no significant difference in time to pass flatus between the 2 groups. Time to ambulate in laparoscopic group was significantly earlier than that in open group. There was no significant difference in time to discharge between the 2 groups, but it was earlier for perineum closure in laparoscopic group. Relative complications of laparoscopic group, including pulmonary infection, abdominal wound infection or split, were significantly less than those of open group. There was no significant difference in number of lymph nodes removed, early recurrence between the 2 groups. Operation cost of laparoscopic group was significantly higher than that of open group, but there was no significant difference.
  
  
  CONCLUSIONS
  Advantages of laparoscopic abdominoperineal resection were characterized for not only minimal invasion and good cosmetic outcome but also less blood loss, complications, and earlier postoperative recovery. The operation time, total costs and oncological clearance of laparoscopic abdominoperineal resection patients were comparable with those of open procedure patients.
