DUODENAL DIVERTICULA: AN ANATOMIC STUDY, WITH NOTES ON THE ETIOLOGIC RÔLE PLAYED BY DYSTOPIA OF PANCREATIC TISSUE

Among the historic considerations that we have reviewed on diverticulum of the duodenum, Chomel, 1 in 1710, is credited with having first described the condition. It is believed by most writers, however, that Chomel's case was probably one of dilatation of the ampulla of Vater which contained twenty-two stones. Case, 2 in 1913, first diagnosed diverticula of the duodenum roentgenologically. Forssell and Key, 3 in 1915, diagnosed a case in which the diverticulum was the first to be removed surgically. Linsmayer, 4 in 1919, reviewed the subject from an anatomic standpoint, as did Odgers, 5 Grant, 6 Herbst, 7 Nagel 8 and others, and Spriggs and Marxer, 9 in 1925, gave an excellent summary from a roentgenologic point of view. In recent years frequent references have been made to the symptoms and complications which may be caused by duodenal diverticula. This is probably due to the increased significance ascribed to
