Details and patient eligibility

About

CSAR Trial's aim is to determine whether the transverse coloplasty pouch or the side-to-end anastomosis as rectal reservoir reconstruction offers the best functional results.

Full description

This study directly compares two neorectal reservoir-techniques, the transverse coloplasty and the side-to-end anastomosis, in low anterior resection in distal rectal cancer for the first time. Its focus is on the functional results. Besides stool frequency, the quality of life, safety of the procedures and the usage of stool modulating drugs is monitored in an 12 months-follow up regime.
