Objective:
To compare the perioperative safety and efficacy between hand-assisted laparoscopic surgery(HALS) and conventional open sigmoidectomy.
Methods:
A total of 291 patients with sigmoid colon cancer who underwent surgery in our hospital from January 2010 to June 2013 were seperated into (HALS) group (n=200) and conventional open surgery (COS) group (n=91) with a non-randomized method. The perioperative safety and efficacy of two groups and perioperative outcomes were compared.
Results:
These two groups were comparable in operative time, lymph node harvest, and postoperative complications. However, HALS group had less intraoperative bleeding [(57.9±28.3) ml vs. (82.5±47.6) ml, P=0.000], shorter time to flatus [(3.0±1.4) d vs. (3.3±0.9) d, P=0.000], and shorter hospital stay [(7.3±4.2) d vs. (8.9±4.4) d, P=0.004]. There werer no significant differences in overall survival time and disease-free survival time between the two groups during 6 months to 3 years follow-up.
Conclusions:
HALS results in similar outcomes of conventional open surgery for sigmoidectomy with the advantage of minimal invasiveness.
