San Diego Intestinal Rehabilitation Focus (SIRF) Program

The San Diego Intestinal Rehabilitation Focus (SIRF) team is a multidisciplinary program that provides consultation, management and long-term follow-up for children and their families coping with complex intestinal disorders such as short bowel syndrome and other conditions resulting in intestinal failure. Intestinal rehabilitation includes strategies and therapies designed to help the bowel work better and harder.

Children with these conditions are complex, and each child requires a unique approach to their rehabilitation. Studies suggest that these children benefit most from a multidisciplinary approach. As such,  our experienced team includes a pediatric gastroenterologist,  pediatric surgeons, nurse coordinator, pediatric nurse practitioner, registered dietitian and social workers so that we can provide comprehensive care to this special needs population. We follow newborns in the neonatal intensive care unit all the way through adulthood.
