Utilization of a Transanal TME Platform to Enable a Distal TME Dissection En Bloc with Presacral Fascia and Pelvic Sidewall with Intraoperative Radiotherapy Delivery in a Locally Advanced Rectal Cancer: Advanced Application of taTME

Abstract

Introduction: The safe introduction of transanal total mesorectal excision (taTME) has been documented by the Australasian group previously. The most important prognostic indicator for rectal cancer is the ability to achieve a clear resection margin. By utilizing false planes for taTME surgery, the endopelvic fascia and or presacral fascia can be resected en bloc. Technique: This case highlights the utilization of a taTME platform to perform a distal taTME with presacral fascial stripping and a lateral pelvic sidewall transanal-assisted dissection in a 53-year-old otherwise healthy woman with a mid-rectal tumor. Radiologically the tumor was staged as a T3c/T4 rectal cancer with an N1c deposi..
