Background:
Faecal incontinence is a common debilitating condition associated with poor quality of life that generates substantial economic strain on healthcare systems.
Objectives:
We aimed to evaluate, in a tertiary referral population presenting with faecal incontinence, the impact of suffering additional disorders of gut-brain interaction (DGBI) on symptom severity, anxiety, depression and quality of life.
Methods:
Design: Retrospective cohort study.
Setting:
Tertiary referral Neurogastroenterology centre.
Patients:
All patients presenting with faecal incontinence from 2007 to 2020 were included.
Main Outcome Measures:
The results from structured medical and surgical questionnaires including Rome III Integrative Questionnaire, Faecal Incontinence Severity Index, Hospital Anxiety and Depression Scale, SF-36, and anorectal physiology were analysed using Stata version 17. Patients were categorised into 3 groups: 0-1 additional DGBI, 2 DGBIs, and 3+ DGBI. Statistical significance was defined as p < 0.05 (two-tailed).
Key Results:
Faecal incontinence patients (n = 249; mean age 63.4 ± 12.6 years; 93.6% female, 48.1% urge subtype) met diagnostic criteria for mean 2.2 additional DGBI each, mostly affecting bowel (n = 231, 42.4%) and anorectal (n = 150, 27.5%) regions. A greater number of DGBIs was associated with higher faecal incontinence symptom severity (p < 0.001), higher anxiety (p = 0.002) and depression (p = 0.003), and worse quality of life in areas of mental health (p = 0.037) and social effect (p < 0.001). Patients with a greater number of concurrent DGBI demonstrated a greater family history of gastrointestinal problems (p = 0.004). There were no associations found between a greater amount of DGBIs and anorectal physiology.
Conclusions And Inferences:
A greater number of additional DGBIs in faecal incontinence patients was associated with worse faecal incontinence symptoms, higher anxiety and depression scores, and worse quality of life but was unrelated to physiology. This highlights the need to proactively search for comorbid DGBI in patients presenting with faecal incontinence.
