[What to expect from expert systems for the diagnosis of functional bowel disorders].
The goal of this study was to evaluate the computer-aided diagnosis systems used for functional intestinal disorders published between 1970 and 1989. The methodology of all prospective studies published was evaluated using a score system of 12 items, filled in by two independent observers. A total of 10 studies were identified. None of the systems studied could truly be considered as an expert system. Most systems were not methodologically sound and the median score was 11 of a possible total of 24. The two principal characteristics of functional intestinal disorders are their high prevalence and the absence of objective diagnostic criteria. Taking these two facts into consideration when elaborating a diagnostic method, expert systems should be useful for teaching purposes and for conducting prospective epidemiologic or therapeutic studies. It seems too early, however, to consider the use of veritable expert systems as an aid to the practitioner in daily practice.
