The results are reported of a systematic research conducted on 684 patients subjected to radiological examinations for the purpose of identifying the three pathologies that constitute Saint's triad in an attempt to contribute to the assessment of its real incidence. The investigation revealed 7 cases of Saint's triad (1.02%) and 86 cases of bifocal associations; 59 cholelithiasis + diverticulosis, 17 cholelithiasis + Hiatus hernia; 10 diverticulosis + hernia. The incidence of the triad was 4 times higher than expected as was revealed by a simple statistical calculation.
