CPT® Code 46712

Repair of ileoanal pouch fistula/sinus (eg, perineal or vaginal), pouch advancement; combined transperineal and transabdominal approach

The CPT® Code 46712 refers to a surgical procedure known as the repair of an ileoanal pouch fistula or sinus, which may occur in areas such as the perineum or vagina. This procedure involves a combined approach that includes both transperineal and transabdominal techniques. An ileoanal pouch is a surgically created reservoir that is formed from the ileum, which is the last part of the small intestine, and is used to collect waste after the removal of the rectum. Fistulas or sinuses can develop as abnormal connections between the pouch and surrounding structures, leading to complications such as infection or leakage. The procedure aims to repair these connections, ensuring the integrity of the pouch and restoring normal function. The surgical approach is comprehensive, involving incisions in both the lower abdomen and the perineum to access and mobilize the pouch effectively. This meticulous technique allows for the excision of the fistula or sinus tract and the reconstruction of the pouch to the anal canal, ultimately promoting healing and improving the patient's quality of life.
