Abstract
Background
The technique of laparoscopic-assisted resection of colorectal carcinoma has been established. However, whether such a procedure is beneficial to patients is uncertain.

Objective
To review the immediate and mediumterm results of laparoscopic-assisted resection in patients with rectosigmoid carcinoma.

Patients and Interventions
We attempted laparoscopic-assisted sigmoid colectomy or anterior resection in 50 patients with rectosigmoid carcinoma (ie, the study group). The results were compared with those of 50 matched patients who underwent conventional open resection in the immediate prelaparoscopic era (ie, the control group).

Results
The median follow-up times for the study and control groups were 32.8 and 39.1 months, respectively. The operating time was significantly longer (P<.001, Student t test), while the analgesic requirement was significantly less (P<.001, Mann-Whitney U test) and the duration of hospitalization was significantly shorter (P=.001, Mann-Whitney U test), in the study group than in the control group. The oncological clearance (ie, the number of lymph nodes removed and the distal resection margin), the complication rate, the disease-free rate, and the survival rate were comparable in the 2 groups.

Conclusion
The immediate and medium-term results of laparoscopic-assisted resection of rectosigmoid carcinoma are promising.
