A novel approach to management of a sacral defect in ileal pouch-sacral fistula

Fistula formation after restorative proctocolectomy poses a challenge to the surgeon and sometimes can lead to the excision of the pouch. While pouch-vaginal fistulas are more common, pouch-sacral fistulas are a rare event and treatment is still controversial. The authors report a case of pouch-sacral fistula which was treated successfully with a novel approach comprising pouch revision, debridement of sacrum and placement of a human acellular dermal matrix (Alloderm) mesh to patch the residual large sacral defect. This is the first report of the use of Alloderm under this rare condition.
