[The feasibility of reduced port surgery for sigmoid colon and rectal (Rs) cancer].

Laparoscopic surgery for colorectal cancer has the advantage of being less invasive and delivering better cosmetic appearance. Although single-incision laparoscopic surgery produces excellent cosmetic results, it is considered very difficult to perform. We performed reduced port surgery (single-incision plus one or 2 ports) on 42 patients in our institute. The operation time, number of dissected lymph nodes, morbidity rates, and length of hospital stay after the operation were not inferior to those in conventional laparoscopic surgery. The estimated blood loss in reduced port surgery was less than in conventional laparoscopic surgery. In conclusion, the procedure of reduced port surgery should be further standardized to make it safer and more feasible, and to provide a favorable cosmetic result for selected patients.
