Intussusception: a case review.
This study is a review of all cases of intussusception from December 1971 to December 1981 at the Erlanger Medical Center in Chattanooga. Only 24 cases were found. A disproportionate number of patients were white (92%). The male to female ratio was 2 to 1. There was no regular seasonal variation. Several patients were below the third percentile in weight for their ages. The most common signs and symptoms were vomiting, pain, and bleeding per rectum. The occurrence of anatomic lead points was high, and the success rate for hydrostatic reductions was low. The use of glucagon before barium enema increased the success rate of hydrostatic reduction by 75%, from four successful reductions to seven of 20 attempts.
