The specific duration of minimally invasive umbilical hernia surgery depends on the actual findings during the exploration. For instance, whether there are severe adhesions inside the patient's abdominal cavity and if there are any associated injuries to the internal organs during the surgery. In most cases, if everything goes smoothly, the surgery can be completed in about two hours. Generally, minimally invasive treatment methods such as intraperitoneal mesh repair are used, typically choosing an anti-adhesion patch. Laparoscopic repair causes even less trauma and allows for the preservation of the umbilicus without the need for extensive dissection. The chances of infection at the surgical site are very low post-surgery, and there is usually no need for drainage, making it particularly suitable for obese patients. Umbilical hernia repairs are generally recommended to be performed as soon as possible once diagnosed in adults, because umbilical hernias can become incarcerated or strangulated.
