Background: Defecatory dyssynergia (DD) is widely recognized as a cause of chronic constipation; however, its prevalence and contribution to fecal incontinence (FI) are not fully understood. Objective: To determine the prevalence of DD in adults with FI and describe their manometric characteristics. Methods: This retrospective observational study included adults with FI evaluated at a specialized center from January 2023 to March 2025. All patients underwent high-resolution anorectal manometry (HRAM) in accordance with the London Classification (LC) standards. DD was defined using these criteria and confirmed with a balloon expulsion test. Statistical analysis included the χ² test or Fisher’s exact test, Student’s t test, or the Mann-Whitney U test, as appropriate, with a significance level set at p < 0.05. Results: A total of 58 patients were included, with a mean age of 53.3 ± 14.9 years. DD was identified in 23 patients; those with DD were older than those without (57.6 ± 2.5 vs. 50.4 ± 15.7 years; p = 0.068). No significant association with sex was observed (p = 0.304). Conclusions: DD was present in 40% of patients with FI, even in the absence of constipation. These findings highlight the importance of systematic functional assessment to guide more personalized and effective pelvic floor rehabilitation strategies.
