Introduction

Piles, fissure and fistula are the three most common conditions seen in any proctology clinic. They are very different problems with very different treatments - but most patients arrive with a single, embarrassed description: 'something is wrong down there'.

Confusion is understandable. All three can cause bleeding, pain or discomfort with bowel movements. Some can occur together. And the cultural awkwardness around discussing the area means patients often try home remedies for years before seeking help.

This article is a clear, plain-language guide to telling the three apart, what causes them, and what modern day-care treatment in Hyderabad looks like.

What are piles, fissures and fistulas?

Piles (haemorrhoids) are swollen blood vessels in the anal canal. They commonly bleed during defecation and can prolapse out - the patient may feel a soft lump that pushes back in, or in advanced cases, has to be pushed back manually. Pain is usually mild unless a clot forms (thrombosed piles).

An anal fissure is a small tear in the lining of the anal canal, usually caused by passing a hard stool. It causes intense, sharp pain during and for several minutes after defecation, and a small streak of fresh blood. The pain is the dominant feature.

An anal fistula is an abnormal tunnel between the anal canal and the skin around the anus. It usually starts as an abscess (a painful, swollen lump near the anus) that bursts and then keeps discharging pus or fluid. The hallmark is recurrent discharge or recurrent abscess in the same spot.

Symptoms & when to seek help

  • Piles: painless or mildly painful bleeding, soft lump that prolapses, itching
  • Fissure: severe sharp pain during and after defecation, fresh blood streak
  • Fistula: recurrent discharge of pus or fluid near the anus, recurrent abscess
  • All three can be aggravated by constipation, straining and a low-fibre diet
  • Persistent symptoms beyond 2 to 4 weeks always need evaluation

Causes & risk factors

  • Chronic constipation and straining
  • Low-fibre, low-water diet
  • Long hours of sitting
  • Pregnancy and childbirth (piles)
  • Spasm of the internal anal sphincter (fissure)
  • A previous anal abscess (fistula)
  • Inflammatory bowel disease (fistula)

How it is diagnosed

  • Outpatient consultation and external examination
  • Digital rectal examination
  • Proctoscopy - a 2-minute outpatient look at the anal canal
  • Sigmoidoscopy or colonoscopy when bleeding could be from higher up
  • MRI of the pelvis for complex or recurrent fistulas

Treatment options

  • Piles, early grades: fibre, fluids, topical agents, rubber-band ligation
  • Piles, advanced grades: laser haemorrhoidoplasty, stapled haemorrhoidopexy or conventional surgery
  • Fissure, acute: topical nitroglycerin or calcium channel blocker ointment, sitz baths, fibre
  • Fissure, chronic: lateral internal sphincterotomy or botulinum toxin
  • Fistula: fistulotomy, LIFT procedure, or laser fistula closure depending on complexity
  • Most modern proctology procedures are day-care, with return to office in 3 to 7 days

Recovery & aftercare

  • Laser piles surgery: day-care, mild discomfort, back to office in 3 to 5 days
  • Conventional haemorrhoidectomy: day-care, more discomfort, back to office in 1 to 2 weeks
  • Fissure surgery: day-care, immediate relief of the pain spasm, full healing in 2 to 4 weeks
  • Simple fistulotomy: day-care, sitz baths for 2 to 3 weeks, full healing in 4 to 6 weeks
  • Complex fistula surgery: may need a seton drain for several weeks before definitive repair

Risks of delaying care

  • Untreated piles can progress to grades that need surgery and have a higher complication rate
  • Untreated chronic fissure can cause persistent pain and sphincter damage
  • Untreated fistula can become more complex, branching and harder to cure
  • Long-standing perianal disease occasionally has rare but serious causes (Crohn's, malignancy) that need exclusion
  • Anaemia from chronic bleeding affects energy, work and quality of life
