Common Anomalies of Duodenum and Colon: Their Practical Significance

This paper embodies the result of eight years' study of those anomalies of the digestive tract susceptible of roentgen demonstration. At various times Drs. Samuel Schechter and Jerome A. Marks have collaborated in this research. The material used for this study comprises a consecutive series of 3,000 private patients complaining of digestive disorders, approximately three fifths of whom had test meals and roentgen surveys in addition to the routine history and physical examination. The statistical method of attack was employed throughout in the belief that this would yield results most likely to be objective in nature and most open to confirmation or refutation by others. Having no preconceived notions to establish, we have been satisfied with presenting the facts first, leaving the matter of speculation to follow later. Nevertheless, before proceeding to a more detailed consideration of individual anomalies, it may be of value to formulate certain generalizations that have
