Background:
Faecal incontinence is a multifactorial disorder, with multiple treatment options. The role of internal rectal prolapse in the aetiology of faecal incontinence is debated. Recent data has shown the importance of high-grade internal rectal prolapse in case of faecal incontinence. We aimed to determine the incidence and relevance of internal rectal prolapse in patients with faecal incontinence without an anal sphincter defect.
Methods:
Patient data, collected in a prospective pelvic floor database, were assessed. All females with moderate to severe pure faecal incontinence, without obstructed defecation and sphincter muscle defects, were included. Data on defecation proctography, anorectal physiology and incontinence scores were analysed.
Results:
Of 2082 females in the database, 174 fitted the inclusion criteria. High-grade internal rectal prolapse was found in 49% of patients and was associated predominantly with urge faecal incontinence. Passive faecal incontinence was more common in low-grade compared to high-grade internal rectal prolapse patients. Maximum resting pressure was lower in older patients and in patients with high-grade compared to low-grade internal rectal prolapse. Internal rectal prolapse grade was not significantly correlated with faecal incontinence severity score.
Conclusion:
High-grade internal rectal prolapse is common in female patients suffering particularly urge faecal incontinence, without anal sphincter lesions. Defecation proctography should be routine in the work up of faecal incontinence.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
