Excerpt
Since total mesorectal excision (TME) was first described in the early 1930s and later popularised by Heald [
1], efforts have been made to standardise the technique, following the correct embryological planes and using appropriate landmarks. Laparoscopic and robotically assisted approaches to the rectum have gained popularity during recent years, compelling colorectal surgeons to develop their skills and knowledge. Transanal TME (TaTME) is a new addition to the approaches in rectal surgery. Despite being associated with several benefits in selected patients, TaTME requires advanced technical skills and, more importantly, knowledge of the pelvic structures, planes and spaces as they are encountered moving cephalad from the perineum. Magnetic resonance imaging (MRI) is the gold standard for imaging of the pelvis and pelvic floor, but understanding of relevant anatomy when performing a new technique may be hampered by difficulty in interpretation of two-dimensional (2D) images when considering three-dimensional (3D) structures. We describe a new tool that could help understanding of TaTME planes and preoperative planning. …
