Brief Summary

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.

Study Arms (2)

Side-to-End

EXPERIMENTAL

Side-to-End Anastomosis as neorectal reconstruction technique in low anterior resection (LAR)

Procedure: Side-to-End Anastomosis

Transverse Coloplasty

ACTIVE COMPARATOR

Transverse Coloplasty pouch as neorectal reconstruction technique in low anterior resection (LAR)

Procedure: Transverse Coloplasty

Interventions

During the scheduled low anterior resection (LAR) in patients with distal rectal cancer and anticipated anastomosis in the mid or distal rectal third, the reconstruction phase of the LAR consists of the implementation of a side-to-end colorectal anastomosis.

Side-to-End

During the scheduled low anterior resection (LAR) in patients with distal rectal cancer and anticipated anastomosis in the mid or distal rectal third, the reconstruction phase of the LAR consists of the implementation of a transverse coloplasty pouch. For this purpose an end-to-end colorectal anastomosis is initially performed, followed by a longitudinal incision of approx. 8-10 cm length proximal of the anastomosis and a subsequent transverse suture in terms of the coloplasty technique.

Also known as: Coloplasty Pouch, Transverse Coloplasty Pouch
