Objective: To evaluate the feasihility, safety and short-term outcomes through technical aspects of middle rectal resection followed by transanal specimen extraction.Methods: Twenty-four consecutive patients with rectal tumor underwent laparoscopic rectectomy followed by transanal specimen extraction over a period of one year and a half.All the patients were satisfied with inclusion criteria of this approach.Intraoperative data as well as short-term outcomes were evaluated respectively.Results: The laparoscopic tectal resection followed by transanal specimen extraction was successfully carried out in all of the 24 patients without intraoperative conversion and additional access.The mean operation time was 182.7 min (range 130-255 min), the mean blood loss was 26.5 ml (range 5-120 ml), the mean postoperative exhaust time was 31.3 hours (range 16-60 hours), and the mean length of hospital stay was 9.5 days (range 8-19 days).One of the patients was detected with anastomotic leakage postoperatively who was dealt with antibiotic course and daily pelvic cavity flush.No infection-related complications and anal incontinence were observed.The mean size of the tumor was 2.1 cm (range from 1.6-3.2 cm), the mean number of harvested lymph nodes was 16.5 (range 6-31) and the mean follow-up time was 8.5 months (range 2-16 months).No signs of recurrence in any of these patients were found till to the last follow-up.Conclusion: The combination of standard laparoscopic rectectomy and transanal specimen extraction could be a well-established strategy and may he considered as an alternative procedure to the conventional laparoscopic rectectomy.
