Quality of Life After Transanal Total Mesorectal Excision Compared to Traditional Total Mesorectal Excision

Completed

• Conditions: Functional Outcome; Quality of Life; Rectal Cancer; Surgery

• Registration Number: NCT06505863
• Lead Sponsor: Cantonal Hospital of St. Gallen

Brief Summary

The improvement in prognosis of rectal cancer through modern therapy modalities rises questions regarding quality of life (QoL) and functional outcomes. Evidence for long-term QoL and functional outcomes of transanal total mesorectal excision (taTME) is not provided in current literature. This study will compare short-term and long-term QoL and functional outcomes after taTME compared to traditional abdominal TME (laparoscopic, robotic, and open approach)

Detailed Description

Quality of life and functional outcomes of patients undergoing taTME or abTME for stage I-III rectal cancer will be analysed. A retrospective propensity score-adjusted analysis of prospectively conducted data will be performed. The primary endpoint QoL will be assessed by the European Organization for Research and Treatment of Cancer core questionnaire (EORTC QLQ-C30). Secondary endpoints are the functional outcomes according to the EORTC QLQ-C30 questionnaire.
