Colonic transit time of radiopaque markers and rectoanal manometry in patients complaining of constipation.
Transit time, rectoanal manometry, and symptoms were studied in 61 patients complaining of constipation. A slow transit, in the colonic area of most of the patients, was found in 49. Rectoanal manometry was abnormal in 40. Both examinations were abnormal in 32 patients, colonic transit only in 17, and manometry only in eight. Finally, both examinations were normal in only four subjects. A transit delay was always associated with less than three stools per week, and straining at stool was constant when rectoanal manometric disturbances were shown. Objective abnormalities appear common in patients complaining of constipation and, correlated with symptoms, suggest that clinical study in constipation could be of more value than usually is believed.
