Clinical Yield of Colonoscopy in Evaluation of Young Women with Constipation: An Age- and Gender-Based Analysis.

Constipation is one of the most common gastrointestinal complaints among women, with a variety of contributing factors. We aimed to assess the role of colonoscopy in evaluating young women with constipation. A multi-center, large cohort, retrospective study included all data from colonoscopies performed between 2016 and 2023 in seven endoscopy departments. The indications and findings of the procedures were collected, and findings of young women aged ≤40 y with constipation as an indication were compared to older women and men of the same age groups. The cohort comprised 377,795 patients, including 198,629 (52.6%) females and 179,166 (47.4%) males. In total, 7872 females underwent colonoscopy for constipation and other indications . In addition, 6852 women were referred for a colonoscopy for constipation only . In sum, 75% of colonoscopies in women <40 y were normal in both cohorts. In inflammatory bowel diseases (IBD) were significantly higher in women <40 y with Ulcerative Colitis (UC) (1.2%) and Crohn's disease (CD) (0.7%), < 0.001). The rate of IBD was lower but still significant in . In both cohorts, diverticulosis and polyp rates exponentially increased with age >40 y, < 0.001. Higher rates of diverticulosis and polyps were found among males <40 y in One case (0.1%) of Colorectal cancer (CRC) was found in <40 y women. Similar IBD and CRC rates were found in males and females of all ages, > 0.05. The diagnostic yield of colonoscopy for investigating isolated constipation in young females is not significant. Diagnostic work-up should be guided by accurate clinical understanding.
