Inguinal hernias usually need to be surgically repaired to prevent intestinal damage and further complications. There is no non-surgical treatment for hernia. If the hernia is detected and corrected early, aside from a small scar there should be no long term complications. The surgery takes about an hour and is usually an outpatient procedure (which means the patient can go home the same day of the procedure). Premature babies that have the surgery may need to stay overnight in the hospital so we can carefully watch them.
Most umbilical hernias in babies close on their own by age 1 or 2. For children, surgery is typically reserved for umbilical hernias that:
During surgery, a small incision is made at the base of the bellybutton. The herniated tissue is returned to the abdominal cavity, and the opening in the abdominal wall is stitched closed. In adults, surgeons often use mesh to help strengthen the abdominal wall.
