Sentinel Pile Diagnosis

Your doctor may check the bump or bulge to rule out other causes such as a tumor for diagnosis.

Most patients believe the pain they are experiencing is due to haemorrhoids. The difference between a haemorrhoid and a skin tag is that haemorrhoid is caused by the collection of swollen blood vessels around the anus, and anal skin tags can come from a healed haemorrhoid.

A doctor can diagnose the sentinel skin tag based on the symptoms and a visual, physical examination. They may perform a digital rectal exam to ascertain unwanted growth in less visible areas. It can be done by -

Anoscopy

This procedure involves inserting a thin, flexible tube with a light and camera at the end of the anal canal. One can provide local anaesthesia to avoid discomfort to the patient.

Sigmoidoscopy

It follows a similar procedure as Anoscopy but involves examining the rectum and lower area of the colon. It is required for people above the age of 40.

Colonoscopy

Your doctor may take tissue samples for biopsy to rule out other causes like tumours before treating the skin tags.
