Anal stricture refers to the narrowing of the anus, which can lead to difficulty in passing stool, among other symptoms. This condition can be caused by various factors, including inflammation, injury, or previous surgeries. Anal strictures can significantly impact an individual's quality of life, necessitating appropriate diagnosis and management.

Diagnosis[edit | edit source]

Diagnosis of anal stricture typically involves a combination of:
