The value of routine histopathological examination after haemorrhoidectomy in patients at low and high risk of anal squamous intraepithelial lesions and cancer

Given the non-negligible incidental detection rate of aSIL and aSCC in both low-risk and high-risk patients, coupled with the cost-effectiveness of histopathological examination, this study suggests that routine histopathological examination should not be restricted solely to high-risk patients. Further study of the benefit of surveillance following clinical detection in low- and high-risk patients is needed.
