BARIUM-ENEMA EXAMINATION AND RECTAL MANOMETRY IN HIRSCHSPRUNG DISEASE

Barium-enema studies and rectal manometry were clearly shown complementary in diagnosing Hirschsprung disease. Of 27 patients studied, 19 had positive barium-enema and rectal manometric studies and were proved histologically to have Hirschsprung disease. Three had positive barium-enemas but normal rectal manometric studies in the first 10 days of life; later monometric studies were positive, and all 3 were subsequently proved to have Hirschsprung disease. Three patients had negative barium-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.
