Is it possible to have an adult intussusception without surgery? I. What is intussusception? Intussusception is a disease of the intestinal tract in which a section of the intestine and its ligament are snapped into the lumen of the intestine to which they are attached, resulting in obstruction of the passage of intestinal contents and causing intestinal obstruction. Acute intussusception is common in clinical practice, while chronic intussusception is usually secondary. Acute intussusception is most often seen in infancy, and is common in infants aged 4-10 months. Because the intestinal function of infants is not yet well developed, it can lead to intussusception when changing the type of food or diarrhea or cold. Second, the clinical typology of adult intussusception. Intussusception in adults is rare, accounting for only about 3% of all cases of intestinal obstruction. Clinically, according to the course of the disease and its clinical manifestations are divided into: 1, acute type: the course of the disease within 3 days; 2, subacute type: the course of the disease in 3 days to 2 weeks; 3, chronic type: the course of the disease in more than 2 weeks. The etiology of intussusception in adults. It is not too much to say that “all adult intussusception is caused by organic lesions”. The function and structure of the intestinal tract in adults is already very perfect, so it will not happen out of nowhere. Most of them have anatomical abnormalities of the intestinal tract, intestinal polyps and intestinal tumors, and most of them are malignant tumors, such as intestinal mesenchymal tumors and intestinal cancer. The clinical characteristics of adult intestinal condyloma: 1. The clinical manifestations are atypical and lack specificity. Rarely appear the typical “triad of signs” like infant intussusception: abdominal pain – jam-like stool – abdominal wax intestine-like mass. Most of them show the symptoms of nausea, vomiting, abdominal distension and non-defecation and non-exhaustion common to mechanical intestinal obstruction. 2, as mentioned above, adult intussusception almost all have intestinal organism, and tumors are common. 3, intussusception has a long course, will be constantly set in and out of the set, so the abdominal pain will be recurrent, when the attack can feel the abdominal mass, or bloody stool. The abdominal pain and lump will disappear after the condom is relieved by itself. 4.X-ray intestinal angiography presents the cup and spring sign as its typical imaging manifestation; ultrasound and CT examination can show concentric circle sign, target sign and sleeve sign; if combined with intestinal tumor, we can see the image of tumor ring-shaped or semi-ring-shaped protruding into the intestinal cavity in the sleeve of sleeve of sleeve expansion. V. Disposition of adult intussusception. Adult intestinal sleeve is almost always caused by organic lesions, and tumors are common, so once diagnosed, early surgery should be performed to remove the sleeve intestine (including tumors) to lift the intestinal obstruction, too much qualitative diagnosis before surgery is superfluous. If the intussusception is clearly caused by malignant tumor, it should not be repositioned by manipulation, but should be treated by standardized radical bowel resection and corresponding lymph node dissection according to the surgical principles of malignant tumor.
