OBJECTIVETo evaluate the feasibility, the radicalness and efficacy of laparoscopy for advanced colorectal cancer.

METHODSFrom June 2006 to December 2007, laparoscopic surgery and open radical resection were performed in 191 cases of colorectal cancer. The curative effect and clinical data were collected and analyzed.

RESULTSThe patients were randomized to two groups, 98 patients underwent laparoscopic surgery and 93 open operation. Five cases(5.1%) were converted to open surgery in laparoscopic surgery group. The average intraoperative blood loss of open surgery group was(279.5+/-189.4) ml, while that of laparoscopic surgery group was(87.2+/-27.1) ml, the difference between the two groups was statistically significant(P=0.011). Within postoperative 48 hours, the intestinal function and early mobile physical activity were restored in 37.8% (37/98) and 30.6% (30/98) patients of laparoscopic surgery group, while in 6.5%(6/93, P=0.000) and 3.2% (3/93, P=0.000) patients of open surgery group, the differences between two groups were statistically significant. The average hospital stay of laparoscopic surgery group was (8.9+/-5.9) d, whereas open surgery group(12.1+/-7.6) d, the difference was statistically significant(P=0.036). No significant differences were found between the two groups in gender, age, tumor location, resection range of surgery, TNM staging, post-operative complication and lymph node harvest(P>0.05).

CONCLUSIONSLaparoscopic surgery is feasible for the patients with advanced colorectal cancer. The radicalness of laparoscopic surgery is similar to that of open surgery, and laparoscopic surgery can provide less intraoperative blood loss, better intestinal function restoration, early mobile physical activity and shorter hospital stay.
