THE RELATIONSHIP BETWEEN COLONIC DIVERTICULOSIS AND SOYBEAN-LIKE SMALL AND ROUND STOOL

Introduction: Small (approximately 1 cm), round stool is often encountered during fiberoptic colonoscopy, but its cause is unclear. In the present study we examined the causal relationship between such stool and diverticula. Patients and methods: The subjects were 36 patients who underwent fiberoptic colonoscopy at Kumagayageka Hospital from October through December 2014. Examined in each patient were the number of diverticula in the colon, the location of diverticula, the number of bowel movements before fiberoptic colonoscopy, and whether stool characteristic of diverticulosis was present . Results: Diverticula were present in 14 of the 36 patients (38.9%), and stool characteristic of diverticulosis was noted in 11 of the 14 patients (78.6%). Of the 22 patients without diverticula, only 1 had stool characteristic of diverticulosis (4.5%). Thus, for indicating the presence of diverticulosis, characteristic stool had a sensitivity of 78.6%, a specifi city of 95.5%, and an accuracy of 88.9%. Conclusion: Small, round stool, which is likely to have been produced by diverticula, is a sign suggesting the presence of diverticula.
