Background:
Restorative colorectal surgery after emergency stoma formation is challenging because of adhesions, altered anatomy, and pelvic dissection. We evaluated the technical feasibility of stoma-site single-port robotics restorative colorectal surgery using the da Vinci SP system.
Methods:
Six patients underwent restorative colorectal surgery through the previous stoma site between January 2023 and December 2024. The Institutional Review Board of Ulsan University Hospital approved this study (2026-02-018).
Results:
Five patients underwent Hartmann's reversal and one underwent completion proctocolectomy with ileal pouch-anal anastomosis. All procedures were completed robotically without open conversion; one required an additional port. Median operative time was 287.5 min and median blood loss was 25 mL. One intraoperative small-bowel injury required resection, and one postoperative abscess required percutaneous drainage. No leakage, reoperation, readmission or mortality occurred.
Conclusions:
This approach was technically feasible in selected patients, but safety events highlight the difficulty of reoperative pelvic surgery. Further studies are required.
