Piles, fissure and fistula: three different problems, routinely confused
All three bring pain or bleeding below, and they are treated completely differently. Most patients arrive having self-diagnosed the wrong one, years late.
These are the complaints people endure longest before mentioning. Years, commonly — managed privately with whatever is sold at a pharmacy counter, and raised only when the bleeding becomes frightening or the pain stops allowing a normal day. Embarrassment is the reason, and it is the single biggest obstacle to treating any of the three.
Three distinct things
- Piles — the cushions of blood vessels inside the anal canal becoming swollen and congested. Bright red bleeding, itching, a sense of fullness, sometimes a lump that descends on straining. Often not especially painful.
- Fissure — a tear in the lining, producing sharp pain on passing stool that lingers afterwards, with spasm of the muscle that keeps the tear from healing. Pain is the dominant feature.
- Fistula — an abnormal track running from inside the anal canal out to the skin, usually following an abscess. Recurring discharge, swelling, and an opening that heals over and breaks down again.
The fissure deserves particular note because of the loop it creates: the tear hurts, the pain causes the muscle to tighten, the tightening reduces blood supply to the tear, and the tear therefore does not heal. Breaking that loop is the treatment, and it is why ointments aimed only at the pain so often fail.
What sits underneath all three
Constipation and straining, in the large majority. Hard stool, long periods on the toilet, and pressure repeated daily for years is what produces piles and what tears the lining. This is why treating the symptom while leaving the bowel habit untouched produces a patient who returns, and why the first part of any plan here is about stool consistency rather than about the anus.
- Low fibre and low fluid intake
- Long-standing constipation, or the reverse — repeated loose stool
- Prolonged sitting, including long hours on the toilet with a phone
- Pregnancy and childbirth
- Heavy lifting, and chronic cough
- Obesity, and long periods of sitting at work
Why an examination is not optional
None of the three can be reliably told apart from a description, and the condition that must not be missed presents identically. A patient who is treated for piles on the basis of a conversation may be a patient whose bowel cancer went unexamined for a year. Where the history or the examination raises that question, the right action is referral for investigation, not a stronger ointment.
Rectal bleeding at any age warrants examination. Over the age of forty, or with weight loss, a change in bowel habit, anaemia or a family history of bowel cancer, it warrants investigation. Severe pain with fever and swelling suggests an abscess, which needs attention urgently.
Questions people ask
- How do I tell piles from a fissure?
- The pattern differs. Piles classically bleed bright red, often painlessly, with itching or a lump that may come down on straining. A fissure is a tear in the anal lining and is dominated by pain — sharp, cutting pain while passing stool that can continue for an hour or more afterwards, with a smaller amount of blood. Pain that severe is more often a fissure than piles, which is the opposite of what most patients assume.
- Is bleeding from the back passage always piles?
- No, and this assumption costs lives. Piles are the commonest cause, but bowel cancer, polyps, inflammatory bowel disease and other conditions bleed in the same way. Bleeding that persists, or comes with a change in bowel habit, weight loss or anaemia, or occurs over the age of forty, must be examined and investigated rather than assumed.
- Can piles be treated without surgery?
- Early-stage piles are usually managed without an operation — the central work is fixing the constipation and straining that produce them, alongside measures for the symptoms. Advanced prolapsing piles, a chronic fissure that will not heal, and a fistula are surgical problems; a fistula in particular does not resolve with medicine because it is an abnormal track that has to be dealt with.
