Intra-abdominal hernias are not rare, with an incidence of about 0.2%-0.9%, but we just don’t recognize them very often. Once an intra-abdominal hernia is complicated by strangulation, the mortality rate is as high as 75%. What is an intra-abdominal hernia? An intra-abdominal hernia is a type of hernia in which the normal tissues of the body run through a defect or hole into an abnormal area. Unlike other hernias that bulge out of the body, an intra-abdominal hernia occurs inside the stomach and is therefore very easy to misdiagnose. The human stomach is not a flat interior like a bucket, but is uneven. Various internal organs and intestinal tracts inside the belly either stick to the abdominal wall and protrude into the abdominal cavity, or hang on the abdominal wall and stray into the abdominal cavity, forming various grooves and trenches. These trenches, or tracts may have a congenital fissure or defect, forming a trap. Intra-abdominal hernias are formed when the intestines and viscera get trapped. Of course, more often than not, this is due to structural changes in the abdominal cavity after an acquired surgery, as well as the formation of adhesive scars. What are the manifestations of intra-abdominal hernia: summarized in four words: “pain, vomiting, distension, and closure” 1. 2, vomiting is vomiting, the patient vomits the food, bile, and even feces. 3, bloating is abdominal distension, abdominal distension is often persistent and gradually aggravated. 4. Closure means that the anus stops venting and defecating, and some patients may pass a small amount of feces. How to diagnose intra-abdominal hernia? Patients with chronic onset present with recurrent intestinal obstruction, and laparoscopic surgical exploration is a good way to diagnose and treat both, after excluding other diseases. Patients with sudden onset often imply acute intestinal obstruction and require close observation in the emergency department. Even if the diagnosis is not clear for a while, as long as the clinical manifestations are obvious, active surgical exploration should be performed to avoid further deterioration of the disease.
