A bulge in the middle of the abdomen on exertion is clinically referred to as an extra-abdominal hernia. It can include white line hernia, umbilical hernia, or incisional hernia of the abdominal wall caused by infection of the incision after abdominal surgery. Whether it is a white line hernia, umbilical hernia, or incisional hernia, the typical clinical presentation is due to increased intra-abdominal pressure due to abdominal exertion, which can cause intra-abdominal tissues and organs, mainly the intestines or omentum, to prolapse outside the abdominal cavity through the abdominal wall defect, usually requiring further ultrasound or CT examination of the abdomen for a definitive diagnosis. For patients with a clear diagnosis of abdominal wall hernia, further hernia repair surgery is usually required, and laparoscopic tension-free repair with a membrane patch is currently advocated to obtain a cure, as traditional surgical repair has a high recurrence rate.
