In patients with prior pelvic radiation undergoing LAR, does an endorectal advancement flap improve healing and reduce complications

the retrieved evidence does not address using an endorectal advancement flap to augment healing of a low anterior resection anastomosis in a previously irradiated patient — the flap in this corpus is a fistula-repair operation (anorectal, rectovaginal, complex perianal), not an anastomotic-reinforcement technique for LAR. so the premise is not supported by anything indexed here.
