A hernia that protrudes from the umbilicus is called an umbilical hernia. There are two clinical categories: infantile umbilical hernia and adult umbilical hernia. Adult umbilical hernias are most commonly seen in obese individuals with weak abdominal walls, middle-aged and older adults, and in patients with chronic diseases with increased intra-abdominal pressure. The contents of the hernia are mostly the greater omentum, followed by the transverse colon and small intestine. The main clinical manifestation is a round hernia mass protruding from the umbilicus when standing, coughing or exerting, which disappears or becomes smaller when lying down. The hernia does not disappear when lying down if the contents are omentum or intestinal canal. If more omentum and intestine protrude, there may be hidden pain and abdominal discomfort. Smaller umbilical hernias are usually asymptomatic. In adult umbilical hernia, the edge of the hernia ring is tougher, less elastic and non-expandable, so the chance of impaction and strangulation is higher than that of infant umbilical hernia. Many patients with chronic unexplained abdominal pain, abdominal distension, and position-related pulling pain are actually associated with umbilical hernia and are often overlooked. Clinically, the diagnosis can be made by routine visualization and palpation. Patients with chronic unexplained abdominal pain, abdominal distention, and position-related pulling pain can be diagnosed by peritoneal imaging and ultrasound, and can be differentiated from other abdominal wall diseases. However, clinically asymptomatic or atypical symptoms of umbilical hernia often lead to serious conditions without effective treatment. Ingrown and strangulated hernia: In adult type umbilical hernia, the hernia ring is narrow and surrounded by tough scar tissue, therefore, ingrown or strangulated hernia occurs more often in adults. The sudden onset of severe pain can lead to mechanical intestinal obstruction, acute peritonitis and systemic toxicity, and even death. 2. Umbilical hernia rupture: In pregnant women or patients with cirrhosis with ascites, severe and difficult spontaneous or traumatic ruptures sometimes occur due to excessive stretching of the abdominal muscles and great tension on the abdominal wall. Surgery is the only effective treatment. In adults, umbilical hernias are not self-healing and are prone to entrapment and strangulation, so they should all be treated surgically. In the past, surgical treatment was contraindicated in patients with ascites secondary to hepatic sclerosis and in elderly patients with severe cardiac and pulmonary disorders who could not tolerate surgery. However, the current application of local anesthesia and various repair materials, most of these patients are able to be surgically treated and cured. The traditional surgical treatment, under general anesthesia or epidural anesthesia, with a large transverse shuttle incision, has the disadvantages of large incision, large trauma, no umbilical preservation, slow recovery, easy recurrence, high cost, and high requirements for the patient’s underlying disease, and is not clinically accepted by most patients. Currently, a small local anesthetic, paramedic curved incision with an incision length of 3-4 cm and tension-free patch repair is used. It has the advantages of small incision, micro-injury cosmetic, umbilical preservation, fast recovery, no recurrence, low cost, as well as the requirement of patient’s underlying disease.
