Reconstruction of an enterocutaneous fistula using a superior gluteal artery perforator flap.

Enterocutaneous fistula is an uncommon complication of surgery for colorectal cancer. However, once a fistula has developed, treatment is complicated by previous treatments. Here, we describe an enterocutaneous fistula that developed after multiple treatments for rectal cancer in a 62-year-old woman. The woman had previously undergone several colorectal surgeries, radiation therapy and five courses of chemotherapy. Four years after the final surgery, an enterocutaneous fistula developed between the small intestine and the sacral skin. The fistula was resected, and the resulting defect was successfully reconstructed with a superior gluteal artery perforator flap.
