About this study

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.

  • Subsequent reoperation for anastomotic failure or locoregional recurrence.
  • Absence of absolute contraindications to reoperative surgery.

Exclusion criteria

  • Primary tumors located proximal to the sigmoid colon.

Treatment and study plan

redo surgery

Procedure

Primary outcomes

  1. Whether postoperative patients with rectal cancer can restore intestinal continuity, that is, defecate through the anus

    Time frame: During the follow-up period, at least two years after rectal cancer surgery

Secondary outcomes

  1. Low Anterior Rectal Syndrome (LARS) Score of patients restoring intestinal continuity

    Time frame: During the follow-up period, at least one year has passed since the intestinal continuity was restored
