MARQUEZ,, Juan Ricardo et al. Using High-Resolution Anoscopy to Detect Anal Dysplasia Due to Papillomavirus in Patients with Inflammatory Bowel Disease. Rev. colomb. Gastroenterol. [online]. 2023, vol.38, n.4, pp.419-429. Epub 26-Fev-2024. ISSN 0120-9957. https://doi.org/10.22516/25007440.1048.
Introduction:
Anal squamous cell carcinoma is rare, but its incidence and mortality have been increasing globally; 90% of cases are related to human papillomavirus (HPV) infection(1,2). Patients with inflammatory bowel disease (IBD) have a higher risk of infection with this virus; an incidence of 5.5 per 100,000 patients has been identified in the IBD group compared to 1.8 in the non-IBD group(3).
Materials and methods:
A descriptive case series study was conducted with 21 patients with IBD and no perianal symptoms between January and July 2022 at the Institute of Coloproctology in Medellín. They underwent anal cytology, HPV genotyping, and high-resolution anoscopy after explanation and acceptance of the procedure. If lesions were found, ablative treatment was performed.
Results:
23% of this cohort had low-grade squamous lesions, while 14.2% had high-grade lesions with dysplasia changes during anoscopy. Besides, 90.4% had positive HPV genotyping, of which 76.1% were high-grade.
Conclusions:
Our study suggests that this series of patients with IBD behaves as a high-risk group for developing premalignant lesions in association with HPV. High-resolution anoscopy is a cost-effective, painless, and affordable method that, in expert hands, may impact the diagnosis and management of premalignant lesions and decrease the incidence of anal cancer in patients with IBD.
