Intestinal necrosis

Intestinal wall necrosis is commonly seen in intestinal obstruction. Obstruction of the intestinal lumen by intestinal contents such as masses of roundworms, gallstones, feces, or other foreign bodies is called intestinal obstruction, which is a type of simple mechanical intestinal obstruction. More commonly, roundworms aggregate into masses and cause local intestinal spasm, resulting in luminal obstruction. It is most common in children, with a higher incidence in rural areas. Clinical manifestations include paroxysmal abdominal pain around the umbilicus and vomiting, and there may be a history of passing or vomiting roundworms.

There is also acute hemorrhagic necrotizing enteritis, which is an acute enteritis associated with Clostridium perfringens type C infection. The lesions are mainly in the small intestine, and the pathological changes are characterized by intestinal wall hemorrhage and necrosis. The main clinical manifestations include abdominal pain, bloody stools, fever, vomiting, and abdominal distension. In severe cases, there may be toxic symptoms such as shock and intestinal paralysis, as well as complications such as intestinal perforation. Neonatal intestinal necrosis is also included. Necrotizing enterocolitis of the newborn is a serious disease with abdominal distension, vomiting, and bloody stools as the main clinical manifestations, and pneumatosis intestinalis as the characteristic X-ray finding. Ninety percent occurs in premature infants, and the mortality rate for those accompanied by intestinal pneumatosis and portal venous gas is as high as 86%.
