Natural orifice specimen extraction with a modified reverse puncture device technique for total laparoscopic colorectal resection: feasibility and efficacy

Objective: To evaluate the feasibility and efficacy of the modified reverse puncture device (mRPD) technique for transanal anastomosis in total laparoscopic colorectal resection with natural orifice specimen extraction surgery (NOSES).Methods: From August 2015 to September 2017, 34 patients underwent laparoscopic colorectal resection using the mRPD technique to place the anvil in the abdominal cavity and complete transanal anastomosis.Results: All patients who underwent total laparoscopic colorectal resection with NOSES were analyzed. The anvil placement time was 5–14 min, with an average of 6.7 min. The postoperative pain visual analogue scale (VAS) score was 1–4 points, with an average of 2.2 points. The postoperative hospital stay was 7–13 days, with an average of 8.7 days. No complications, such as anastomotic bleeding or stenosis, occurred. During a 14- to 28-month follow-up period (average, 19.5 months), no cases of long-term complications were observed.Conclusion: Total laparoscopic colorectal resection using mRPD is a technically feasible and safe procedure with satisfactory short-term efficacy.
