Adult intussusception tumors are more malignant, with some studies showing the chance of malignancy ranging from 30% to about 80%. Intussusception is common in children, adult intussusception is relatively rare, accounting for about 5% of all intussusceptions, and intussusception accounts for 1% to 5% of intestinal obstructions in adults. Adult intussusception is mostly secondary, >90% have a clear cause. Some studies have shown that the malignancy rate of small bowel intussusception in adults is about 30%; the malignancy rate of colonic intussusception is about 80.0%. However, the above studies are small samples and can only be used as a reference and do not represent authoritative views. It should be noted that if intussusception is detected, early repositioning treatment and application of air or barium enema is not only a diagnostic method, but also an effective treatment. Adult intussusception mostly has pathological factors that cause intussusception, and surgery is generally advocated after a clear diagnosis. If the intussusception can not be reset, or the duration of the disease > 48 hours, or suspected intestinal necrosis, surgery is required. The severity of intussusception varies, and it is recommended to actively seek medical attention and timely treatment to avoid delaying the condition.
