Objective:To discuss the strength and weakness of hand-assisted laparoscopic surgery(HALS) and laparoscopic-assisted surgery(LAS) in laparoscopic left colon resection used by beginners and less experienced surgeons and to guide the surgeons to make a selection. Methods:Totally 53 cases underwent HALS and LAS by less experienced laparoscopic surgeons were divided into two groups:A group(29 cases;less experienced laparoscopic surgeons(performing less than 30 cases of laparoscopic colon surgeries) performing HALS) and B group(24 cases;surgeons with the same experience performing LAS). Clinical data were statistically ana-lyzed. Results:There was no significant difference in general condition between the two groups. There were statistical differences in cases converting to laparotomy(10.3% vs. 16.7%,P=0.688),cases of comfort/slightly discomfort/discomfort(2/15/9 vs. 1/12/7,P=1.000),operative time((177.7±28.8) min vs. (204.1±36.6) min,P=0.009),blood loss((104.4 ± 33.7) ml vs. (164.25 ± 65.00) ml,P=0.001) and hospital costs((45 819.96 ± 4 793.40) Yuan vs. (42 375.50±5 234.74) Yuan,P=0.024). There was no difference in anal exhaust time,postoperative hospital stay and number of dissected lymph node((64.4±21.4) h vs. (64.5 ± 19.0) h;(13.6±4.5) d vs. (12.3±3.5) d;(16.0±3.3) unit vs. (17.0±3.6) unit;P=0.985,0.166,0.125). Conclusion:HALS can be used as one of the preferred methods for less experienced laparoscopic surgeons.
