AIM: Rectal prolapse is a full-thickness intussusception of the rectum beyond the anal canal. It is often mistaken for other anorectal pathologies, leading to inaccurate referrals to colorectal surgeons and inappropriate management. However, the frequency of misdiagnosis is not well characterized. We aimed to assess the diagnostic accuracy of rectal prolapse referrals to three tertiary medical centres.
METHODS: This is a retrospective study of patients referred for rectal prolapse to colorectal surgeons at the Mayo Clinic in Rochester, Jacksonville, and Phoenix from 2020 to 2024. The primary outcome is the accuracy of rectal prolapse diagnosis. The secondary outcomes are factors that correlate with diagnostic accuracy.
RESULTS: Rectal prolapse was inaccurately diagnosed in 38.7% (186/480) of patients. Among misdiagnosed patients, the correct diagnosis was haemorrhoids (68.0%, n = 134), pelvic floor dysfunction (24.3%, n = 48) and rectocele (18.7%, n = 37). A diagnosis of rectal cancer was found in 3 patients (1.5%). The most common presenting symptoms were protrusion (66.3%, n = 345) and bleeding (33.6%, n = 175). Among the referring physicians, only 50.5% (n = 227) performed an anorectal examination. Overall, there was significant variability in diagnostic accuracy across different specialties, with the highest accuracy from colorectal practices (84.0%) and the lowest from urologists (50.0%). Internal medicine physicians had a lower diagnostic accuracy with anorectal examination than without, though it did not reach statistical significance (44.0% vs. 59.5%, p = 0.2).
CONCLUSION: Over one-third of rectal prolapse referrals were incorrectly diagnosed. This study highlights the opportunity for further training of referring providers on anorectal pathologies to improve diagnostic accuracy which could reduce treatment delays and optimize clinical outcomes.
