Give a brief description of your assigned pathology; include its definition, location (small or large intestine & relationship to peritoneum – see table 13.1 p 491), etiology (cause, set of causes, manner of causation), signs/symptoms, diagnosis, treatment, prevention (preventative measures), most common radiographic examination, and radiographic appearance/presentation. en-us 2021-04-17 22:50:39 UTC 2025-10-02 20:44:30 UTC hello@padlet.com https://padlet.net/icons/png/1f480.png Intussusception havrone https://padlet.com/havrone/uqvpe3guyjxdb5fd/wish/1428881435 Intussusception is a condition which involves part of the intestine sliding into an adjacent part of the intestine, blocking food or fluid from passing through. This action also causes the blood supply to part of the intestines to be cut off. When blood supply is cut off to the intestine bowel perforation, infection and even death of the tissue can occur.

Most cases of intussusception present in children, under the age of 3, in which blood/mucus mixed stool, vomiting, lump in the abdomen, diarrhea and fever may be present. The cause of most of these cases is unknown, but seems to occur more often during the fall and winter months. Although rare in adults, it is more challenging to identify, it can be caused as a result of medical conditions/procedures such as: polyps/tumors, scar-tissue, gastric bypass surgery or Crohn’s disease.

Diagnostic imaging used to identity intussusception includes abdominal x-rays, which demonstrate an elongated soft tissue mass with a bowel obstruction. Children often present the soft tissue mass in the upper right quadrant. Gas may be absent in the collapsed bowel. Fluoroscopy exams, using a contrast enema, demonstrate intussusception as a mass prolapsing into the lumen. The barium in the lumen, paired with barium in the intraluminal space, presents a coiled spring appearance. The contraindication for an contrast enema if perforation. Ultrasounds is a reliable screening for children at low risk for intussusception, but children with classic finds should under-go a fluoroscopy examination. Ultrasound clinical indications include a “target sign” (also known as the doughnut sign) or crescent in a doughnut sign. CT imaging appearance of intussusception depends on the imaging plane and where within the bowel that the images are obtained. However, when the layers of the bowel are duplicated (forming concentric rings), a bowel-within-bowel configuration is present.

Treatment, in children, usually includes a using a rectal catheter to exert pressure to reduce the intussusception. However, surgery may be required if peritonitis is present or enema reduction is unsuccessful.
