Background
The techniques of intracorporeal anastomosis and specimen extraction after laparoscopic colectomy via a natural orifice have gained interest increasingly. We evaluated the feasibility of our unique techniques for colorectal reconstruction and report immediate postoperative outcomes in patients with rectosigmoid cancer.
Methods
Patients with sigmoid or rectal cancer were selected depending on the size of the tumor and its distance from the anal verge. Demographic data, operative parameters, and postoperative outcomes were assessed. After complete resection of the tumor, all patients underwent an intracorporeal side-to-end colorectal anastomosis following transrectal specimen extraction.
Results
Laparoscopic resection with our technique of intracorporeal anastomosis was successful in 32 patients. The average operative time was 192 ± 29 min, and mean blood loss was 51 ± 18 ml. All patients experienced mild postoperative pain, and bowel function returned before postoperative day 3 in most patients. They had an uneventful postoperative course with a median hospital stay of 6 days. Major perioperative complications or anastomotic leak were not encountered in this study. The mean size of the lesion was 3.3 ± 1.8 cm, and the mean number of harvested nodes was 14 ± 6. During the follow-up period, there were no functional disorders associated with the intracorporeal anastomosis or transrectal specimen extraction.
Conclusions
Intracorporeal side-to-end colorectal anastomosis with transrectal specimen extraction in laparoscopic colorectal surgery is a safe and effective procedure for patients with rectosigmoid malignancy.
