|Haemorrhoids (Piles)
๐ Key sign: Bright red blood on stool, toilet paper, or dripping into the bowl. Pain may occur if thrombosed or prolapsed.
๐ About
- Haemorrhoids are vascular cushions at the anus, not simply varicosities.
- Located at the 3, 7, and 11 oโclock positions (lithotomy view).
- Help maintain continence, but when enlarged โ symptomatic haemorrhoids.
- Affect ~10% of the population, peak between ages 45โ65.
โ ๏ธ Aetiology / Risk Factors
- Chronic constipation, straining, low-fibre diet.
- Increased intra-abdominal pressure: pregnancy, ascites, chronic cough.
- Internal haemorrhoids: arise above dentate line, usually painless (unless strangulated).
- External haemorrhoids: arise below dentate line, often itchy or painful.
๐ฉบ Clinical Features
- Anal discomfort, sensation of โsomething there.โ
- Bleeding: bright red, usually on wiping rather than mixed with stool.
- Thrombosed or prolapsed piles โ severe pain.
- Rectal fullness, pruritus, occasional continence issues.
- May require proctoscopy for diagnosis (not always palpable).
๐ Classification
- 1๏ธโฃ First degree: Remain in rectum, not visible.
- 2๏ธโฃ Second degree: Prolapse with defaecation, reduce spontaneously.
- 3๏ธโฃ Third degree: Prolapse, require manual reduction.
- 4๏ธโฃ Fourth degree: Persistently prolapsed, irreducible.
๐ Investigations
- FBC, U&E, CRP to exclude other pathology (anaemia from haemorrhoids is rare).
- Proctoscopy for direct visualisation.
โ ๏ธ Complications
- Thrombosis, ulceration, gangrene, perianal infection.
๐ Differentials
- Perianal streptococcal infection, herpes simplex, perianal candidiasis.
- Always consider colorectal malignancy in persistent rectal bleeding.
๐ Management
- ๐ฏ Conservative: Hydration, high-fibre diet, bulk laxatives, topical agents (e.g. Anusol suppositories/creams after defaecation, morning & night).
- Local topical preparations may combine anaesthetics, corticosteroids, astringents, lubricants, and antiseptics.
- โ๏ธ Thrombosed piles: bed rest, analgesia, ice packs. May resolve or leave skin tags. Consider emergency haemorrhoidectomy in severe cases.
- ๐ฉน Procedures:
- Rubber band ligation โ for 1st/2nd degree haemorrhoids.
- Injection sclerotherapy (phenol in oil) โ for 1st/2nd degree.
- HALO (haemorrhoidal artery ligation operation) โ less invasive option.
- Haemorrhoidectomy โ if refractory to first-line measures.

Clinical Cases
- ๐ฉธ Case 1 โ Age 28: Presented with painless bright-red rectal bleeding noted on toilet paper after defecation. Examination revealed small, non-thrombosed internal haemorrhoids (grade I). Managed conservatively with high-fibre diet, hydration, and topical hydrocortisone.
- ๐ข Case 2 โ Age 46: Complained of prolapsing anal lumps and discomfort after straining. Found to have grade III mixed haemorrhoids requiring rubber band ligation. Education given on bowel habits and avoidance of prolonged sitting.
- ๐ Case 3 โ Age 62: Presented acutely with severe anal pain and a tender bluish perianal swelling. Diagnosed with thrombosed external haemorrhoid. Treated with analgesia, topical lidocaine, and sitz baths; surgical excision discussed if pain persisted.
