Area of Science:

  • Colorectal Surgery
  • Surgical Anatomy
  • Minimally Invasive Procedures

Background:

  • Transanal total mesorectal excision (taTME) presents technical challenges in identifying the correct dissection plane.
  • Dissection errors can lead to complications such as bleeding and nerve injury.

Purpose of the Study:

  • To identify and demonstrate visual features that guide surgeons in maintaining the correct dissection plane during taTME.
  • To reduce the risk of complications associated with incorrect plane dissection in taTME.

Main Methods:

  • Demonstration of specific visual features encountered during taTME surgery.
  • Utilizing video to illustrate correct and incorrect dissection planes.

Main Results:

  • The use of 'triangles' formed by appropriate traction facilitates precise dissection in the correct plane.
  • Recognition of 'O' shapes alerts surgeons to potential fascial plane entry, aiding avoidance of incorrect planes.

Conclusions:

  • Understanding and recognizing specific visual cues during taTME surgery are crucial.
  • Facilitating safe and accurate total mesorectal excision dissection through improved plane identification.
