Laboratory investigation is usually not helpful in the evaluation of patients with intussusception, although leukocytosis can be an indication of gangrene if the process is advanced. With persistent vomiting and sequestration of fluid in the obstructed bowel, dehydration and electrolyte imbalance occur.

Ultrasonographic imaging has been found to have a high sensitivity and specificity in the detection of ileocolic intussusception. Abdominal radiographs can also reveal diagnostic characteristics of intussusception, but their sensitivity and specificity has been called into question.

If a segment of intestine is resected at the time of operative reduction, intestinal obstruction with edema, congestion, lymphocytic infiltration, and transmural infarction are typical findings.
