Arms

  • Arm: Rectal surgery with powered mechanical anastomosis performed with DS or TTSS techniques
    This is an international cohort (France and other international centers) which consists of including patients undergoing rectal surgery with powered mechanical anastomosis performed with DS or TTSS techniques. Surgeons at each center perform one or both techniques. When both types of stapling are possible, the choice of technique is made by the surgeon during the preoperative consultation, in the best interest of the patients, after a case-by-case assessment.

Primary Outcome Measure

To assess and compare the rate of anastomotic leakage at 1 month after rectal excision between double and single-stapling low colorectal anastomosis using advanced powered stapler [ Time Frame: From the surgery to one month ]
