Transverse Coloplasty vs. Side-to-end Anastomosis Following Low Anterior Resection (LAR): CSAR Trial

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.

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.
