Umbilical hernia is a common pathology that occurs in around 2% of the population. About 10% of abdominal hernias are umbilical hernias and umbilical hernia repair is among the most commonly performed surgeries in adults. The diagnosis is straightforward when tissues or organs such as the omentum or a bowel segment bulge out through an opening in the muscles of the abdominal wall in the umbilical region. The treatment options for umbilical hernia include non-operative and operative management strategies via open or minimally invasive techniques. This chapter provides a comprehensive review of umbilical hernias in adults.
