The Barium-Enema Examination and Rectal Manometry in Hirschsprung Disease

Abstract
Ba-enema studies and rectal manometry were clearly shown complementary in diagnosing Hirschsprung disease. Of 27 patients studied, 19 had positive Ba-enema and rectal manometric studies and were proved histologically to have Hirschsprung disease. Three had positive Ba-enemas but normal rectal manometric studies in the 1st 10 days of life. Later manometric studies were positive, and all 3 had Hirschsprung disease. Three patients had negative Ba-enema and positive manometric studies and were proved to have low segment Hirschsprung disease. If both studies indicate the disease, rectal biopsy is not necessary before surgery.
