How to treat small intestinal intussusception

Intestinal intussusception is a disease that is common in infants and young children. Children under 2 years old are particularly susceptible to this disease. After becoming ill, patients will experience abdominal pain, vomiting, and bloody stools, so once parents find that their children have these symptoms, they should conduct timely examinations and treatments. Although intussusception is more common in infants and young children, adults can also suffer from this disease. Adult patients may have recurrent attacks, so they should pay more attention to the choice of treatment method.

Intussusception is when a segment of the intestine is inserted into the adjacent intestine, causing a blockage in the passage of intestinal contents. Intussusception accounts for 15% to 20% of intestinal obstructions. There are two types: primary and secondary. Primary intussusception occurs mostly in infants and young children, while secondary intussusception is more common in adults. The vast majority of intussusceptions are caused by the proximal bowel invagination into the distal bowel. Reverse intussusception is rare, accounting for less than 10% of the total number of cases.

treat

1. Intussusception in children is mostly primary and can be reduced by air or barium enema. However, it is contraindicated in patients with suspected intestinal necrosis.

2. If enema cannot reduce the intestinal tract, or if intestinal necrosis is suspected, or if it is secondary intussusception, surgical treatment can be performed. The specific surgical method should be determined based on the exploration results. For patients without intestinal necrosis, surgical reduction is performed; if there are difficulties, the neck of the outer sheath is incised to reduce the intestinal tract, and then the intestinal wall is repaired; for patients with necrosis or combined with other organic diseases, intestinal resection and anastomosis or ostomy can be performed.

prevention

1. Diarrhea should be avoided, especially diarrhea in autumn. Parents should be highly vigilant about the occurrence of this disease.

2. Pay attention to scientific feeding, do not let the baby starve or overeat, change food at will, and add supplementary food gradually, do not rush.

3. Pay attention to climate changes, add or remove clothes at any time, and avoid various adverse factors that may easily induce intestinal motility disorders.

4. If a healthy infant or child suddenly has unexplained paroxysmal crying, pale complexion, cold sweats, vomiting, bloody stools, and lethargy, one should consider the possibility of intussusception.

5. The main symptoms are abdominal pain, vomiting and jam-like bloody stools.

Classification

1. It can be divided into primary and secondary types. Primary intussusception occurs in the intestine without pathological changes and mostly occurs in children. Children have active intestinal motility, and when they start adding complementary foods, intussusception may occur due to intestinal motility disorders. Upper respiratory tract or gastrointestinal tract infections in children are often accompanied by enlargement of the mesenteric lymph nodes, which may also affect the normal peristalsis of the intestine and cause intussusception. Intussusception in adults often occurs in the intestine with diseased parts, such as benign or malignant tumors, polyps, tuberculosis, adhesions and Meckel's diverticulum, which can affect the normal peristalsis of the intestine and become a predisposing factor for intussusception. Sometimes intestinal ascariasis and spastic intestinal obstruction are also factors of the disease. Adenovirus infection is associated with the onset of disease, with the distal ileum showing significant hypertrophy and swelling, serving as the starting point of intussusception. In a small number of children, intussusception has obvious mechanical factors, such as Meckel's diverticulum, polyps, tumors, intestinal wall hematoma (such as Henoch-Schonlein purpura), etc., which serve as inducements and become the starting point of intussusception.

2. Intussusception can occur in any part of the gastrointestinal tract. According to the part of the intussusception, it can be divided into jejunum within jejunum, jejunum within ileum, ileum within ileum, ileum within cecum, ileum within colon, colon within colon (occasionally sigmoid colon invaginated into the rectum), etc. Among them, ileum within cecum, also known as ileocecal type, is the most common; small intestine within small intestine, also known as small intestine type, is less common; colon within colon, also known as colon type, is very rare. Even more rarely, the upper end of the jejunum retrogradely invaginates into the stomach. After the invaginated intestinal segment enters the sheath, its apex can continue to advance along the intestinal tract, and the mesentery is also pulled in. The mesenteric blood vessels are compressed, causing local circulatory disorders, gradual intestinal edema, intestinal obstruction, strangulation and necrosis of the invaginated intestinal segment, and the sheath expands and shows ischemic necrosis, and may even perforate and cause peritonitis.
