Heineke -Mikulicz Pyloroplasty - The Observer Error in the Interpretation of the Films

Barium meals done before and after Heineke-Mikulicz pyloroplasty on 29 patients undergoing surgery for duodenal ulceration ware studied. Representative views of the pre- and post-pyloroplasty examinations were arranged in a random fashion on unexposed film. Eight radiologists studied the films on 2 occasions. Five sets of films at the first view:ng and 6 sets of films at the second viewing were correctly interpreted. This observation cannot be related to the completeness or incompleteness of the vagotomy, but does appear to be related to the experience of the radiologist.S. Afr. Med. J., 45, 1375 (1971
