Intussusception pdf

The appearance of intussusception on CT is characteristic and depends on the imaging plane and where along the bowel the images are obtained. Best known is the so-called bowel-within-bowel configuration, in which the layers of the bowel are duplicated forming concentric rings CT equivalent of the ultrasonographic target sign when imaged at right angles to the lumen, and a soft tissue sausage when imaged longitudinally As one images further along the intussusception the mesentery fat and vessels will form a crescent of tissue around the compressed innermost lumen, surrounded by the two layers of the outer enveloping bowel.

Even further distally the lead point if present will be visualized In children, intussusception reduction can be achieved without recourse to surgery in most cases. Using a water-soluble medium or air introduced via a rectal catheter, retrograde pressure can be exerted to reduce the intussusception.

If symptoms have been protracted, rectal blood is present; there are signs of peritonitis or enema reduction is unsuccessful then surgical intervention is usually required.

In adults, a laparotomy is usually required, especially as in most cases a lead point requiring treatment is present. On imaging the appearances on ultrasound and CT are characteristic. The main differential is that of transient intussusception , which is an incidental finding requiring no treatment or follow-up.

Figure 1: gross pathology: cecal intussusception Figure 1: gross pathology: cecal intussusception. Intussusception is clinically important. It results in venous obstruction and bowel-wall oedema that can progress to bowel necrosis, perforation, and, rarely, death.

This review will focus on idiopathic intussusception in infants. Intussusception in older children and adults is rare and is almost always caused by a pathological lead point. Gribar, and Dr Rahul J.
