About this trial

Natural Orifice Specimen Extraction (NOSE) eliminates the need for additional abdominal incisions in minimally invasive colorectal procedures, potentially reducing the risk of wound complications and postoperative pain. In the context of restorative Total Mesorectal Excision (TME), single-stapling (SS) techniques facilitate NOSE through transanal rectal transection, as opposed to the conventional double-stapling technique. This study aims to explore the potential advantages of NOSE combined with SS anastomosis compared to conventional abdominal extraction in minimally invasive restorative TME.
