[Analysis of 21 cases treated by total laparoscopic rectosigmoid cancer surgery with transanal natural orifice...

To evaluate the feasibility, safety and short-term outcomes of total laparoscopic rectosigmoid cancer surgery with transanal natural orifice specimen extraction.

From July 2012 to February 2013, 21 patients underwent total laparoscopic surgery with transanal natural orifice specimen extraction. There were 12 males and 9 females with a median age of 53 (48-77) years.Rectal cancer (n = 11) and sigmoid cancer (n = 10) were diagnosed. The clinical data such as bowel function recovery time, number of lymph nodes harvested and an incidence of anastomotic leakage was collected and retrospectively analyzed to assess the value of this technique.

Operation was successfully accomplished without conversion into open surgery or conventional laparoscopic-assisted surgery. The median operative duration was 105 (80-165) min, the median volume of blood loss 50 (20-300) ml, the median number of lymph nodes harvested 16(8-29) and the time of first bowl movement was 48 (24-72) h. The postoperative hospitalization stay was 9 (6-12) d. There were abdominal hemorrhage (n = 1) and anastomotic leakage (n = 1).

Total laparoscopic rectosigmoid cancer surgery with transanal natural orifice specimen extraction appears to be feasible, and oncologically acceptable for selected patients.
