Laparoscopic modified double stapling technique with transanal resection for low anterior resection of rectal cancer

Anterior resection of the rectum with a total mesorectal excision is the standard surgical technique for the treatment of rectal cancer. Laparoscopic low anterior resection (LALAR) is an alternative to open surgical approach and was validated in diverse randomized control trials to be as safe and oncologically effective. That said, confronting a low rectal tumor in an obese patient with a narrow pelvis can be technically challenging even for the most expert surgeon.

We propose a modified double stapling technique with transanal eversion and staple resection of the rectal stump.

We applied the above technique in 3 patients with a dubious distal resection margin due to patient/tumor characteristics. The mean length of operation was 272 minutes and a R0 resection with a mean number of 16 nodes could be obtained in all the patients. No recurrence occurred during a follow-up of 28 months.

We conclude that this technique is a feasible, safe and valid adjunct to the double staple technique whenever intraabdominal application of the linear staple is difficult or unsafe.
