Injection sclerotherapy Sclerosant agents used
- include phenol (5%) in almond oil or sodium tetradecyl sulphate.
- submucosa around the pedicle of the pile, at the level of the anorectal ring.
- The sclerosant causes local inflammation, leading to reduced blood flow into the haemorrhoids.
- The sclerosant also causes fibrosis, which draws minor prolapse back into the anal canal.
- This technique is about 70% effective.
- The correct plane is shown by elevation of the mucosa without blanching during injection.
- Inadvertently deep injections can cause peri- rectal fibrosis, infection and urethral irritation.
- Prostatic injection is intensely painful and the pa- tient may develop an erection, a strong desire to void, haematuria or haemospermia.
- Severe sepsis is not uncommon and such patients should be admitted for antibiotics and observation until completely well.
Known to causes retroperitoneal sepsis and rectal perforation
Urological sepsis can result from a misplaced deep anterior injection with complications such as prostatic abscess, epi- didymitis, chronic cystitis, seminal vesicle abscess and urinary–perineal fistula
