Subjects having endoscopic evaluation at the University of Oklahoma Hospital formed the study group. Patients seen at the general medicine clinic of the University of Oklahoma served as controls. We recorded the patient s name, age, sex, race, history of smoking, and history of appendectomy or tonsillectomy. There were no differences based on race or history of smoking. Multiple regression revealed that history of appendectomy and not tonsillectomy was related to the performance of endoscopy.
History of appendectomy is associated with greater performance of endoscopy.
