To the Editor:—
Accolades to Dr. Homer V. Hartzell for his courageous communication, "To Err With Air," in the Feb 8 issue (JAMA187:455). For a number of years I have been doing air contrast studies, since the informed clinicians and radiologists have assumed this was the ultimate refinement in x-ray diagnosis of colonic lesions. I have often felt inadequate because double shadows may appear like neoplastic lesions and air bubbles may appear like polyps. I believe that radiology would be better served by use of additional films for lateral, oblique, or the Lapine-Chassard position, which may unfold the sigmoid and demonstrate a hidden lesion in this "blind spot."
