To compare the recently clinical therapeutic effect of hand-assisted laparoscopic and pure laparoscopic surgery for colorectal tumors. In addition we evaluated the safety of hand-assisted laparoscopic in curing the colorectal tumors.

Retrospectively chose 79 patients with colorectal tumors from November 2011 to April 2014 in Second Affiliated Hospital of Harbin Medical University.The number of patients who received the abdominal laparoscopic colectomy is 41,the number of hand-assisted laparoscopic colectomy is 38. According two kinds of surgical procedures into abdominal laparoscopic group (LAC group) and hand-assisted laparoscopic group (HALS group). By retrospectively analysis, compared the general information of two groups of patients including age, sex, tumor location, tumor histological type, stage, ASA grade, BMI index; surgery information, including operative time, anesthesia time, blood lossing, laparotomy rate specimens incision length, trocar numbers, etc; postoperative data including exhaust time, postoperative hospital stay, cost of hospitalization, postoperative complications, etc.

There has a difference between HALS group and LAC group in operative time, anesthesia time, blood lossing, Trocar used numbers, specimens incision length (P<0.05). But the difference of postoperative hospital stay, cost of hospitalization , postoperative complications have no significant (P>0.05).

The result of comparing the two types of surgical procedures in colorectal tumors, hand-assisted laparoscopic and pure Abdominal laparoscopic, HALS have many advantages like the shorter operative time, less invasive, quick recovery, hand-assisted laparoscopic is a a safe, effective and reliable technology.
