RESUMO
Waardenburg syndrome is a genetic disease characterized by hearing loss and pigmentation abnormalities. Waardenburg syndrome type 4 is very rare, and children with Waardenburg syndrome type 4 present with intestinal aganglionosis. The associated findings and severity of Waardenburg syndrome type 4 may also differ significantly between cases. Intestinal insufficiency is probable and creates difficulties in terms of treatment; intestinal transplant may be required. In this case report, we present 4 cases of patients with Waardenburg syndrome who have intestinal issues, 2 of whom underwent small bowel transplant. Appropriate surgical and nutritional management should be provided for patients with Waardenburg syndrome type 4 who have gastrointestinal manifestations.
