Redo surgery is a critical salvage strategy for anastomotic complications or local recurrence following rectal cancer resection. Despite technical feasibility, functional outcomes remain suboptimal. This study evaluated intestinal continuity restoration and anal function recovery after redo surgery, alongside prognostic factors influencing outcomes. A retrospective multicenter study analyzed 143 patients undergoing redo surgery (2015-2023) for anastomotic failure or local recurrence. Primary endpoints included anatomical restoration of intestinal continuity, while secondary endpoints assessed functional outcomes using the LARS score.
