Ascariasis is not usually grouped among the diseases requiring surgical intervention, and its presence in what may be called a surgical form is probably seldom diagnosed prior to operation. Ascariasis of the gallbladder is especially unusual, if one may judge by the infrequency with which it has been recorded in the literature. The finding of an ascarid in the gallbladder of a woman on whom I recently performed an operation for cholecystitis suggested this study.
The literature contains numerous references to cases in which ascarids were found in other unusual sites: the urinary passages, the appendix, the pancreatic duct, the common bile duct and the hepatic ducts. Ascarids in these locations were credited with causing many types of symptoms, chiefly those of obstruction and inflammation, presenting, however, few if any pathognomonic peculiarities. DaCosta1 in his textbook on surgery, does not mention ascariasis among the diseases of the gallbladder.
