This page answers frequently asked questions about foam sclerotherapy for internal haemorrhoids. This outpatient procedure may be offered in appropriate cases after confirming the diagnosis and assessing symptoms, disease grade, current treatments and possible alternatives.
Rectal bleeding should not automatically be attributed to haemorrhoids. The initial consultation also identifies any signs that require different investigations. The main clinical page describes haemorrhoid sclerotherapy in Naples.
1. What is haemorrhoid sclerotherapy?
It is an outpatient procedure in which a sclerosant medicine is injected into internal haemorrhoidal tissue. The controlled local reaction may reduce bleeding and the volume of treated tissue. There are no incisions or stitches, and general anaesthesia or hospital admission is not normally required.
2. When may it be indicated?
It may be considered particularly for symptomatic internal haemorrhoids, especially where bleeding predominates and conservative measures are insufficient. Possible indications in cases of prolapse, congestion or more complex symptoms depend on the consultation. External haemorrhoids, acute thrombosis, substantial prolapse or other anorectal conditions may require different approaches.
3. How does sclerosant foam work?
The foam formulation increases contact between the medicine and the tissue being treated. The aim is a controlled local response and gradual symptom reduction. Improvement may take days or weeks, and the same result cannot be guaranteed for everyone.
At Centro Medico Gargano, the foam is prepared with the automated Varixio® system. Standardising preparation reduces technical variation but does not by itself establish definite clinical superiority over every manual preparation method: appropriate indications and individual response remain decisive.
4. Is treatment painful?
The procedure is generally well tolerated when the injection is placed correctly, but some people may feel pressure, burning, pain or tenesmus. It is not appropriate to describe it as always painless. Possible symptoms after treatment and signs that should prompt contact with the doctor are explained beforehand.
5. Is preparation required?
Fasting or bowel preparation on the previous day is not normally required for the first consultation or possible sclerotherapy unless the doctor advises otherwise. You must disclose anticoagulant or antiplatelet medicines, allergies, pregnancy, bowel disease and previous procedures. Do not stop any treatment on your own initiative.
Initial consultation and possible treatment at the same appointment
If assessment confirms the diagnosis, indication and safe conditions, sclerotherapy may sometimes be performed during the same appointment. This is decided individually and cannot be guaranteed before the consultation.
6. How long does it take, and how many sessions may be needed?
The technical part is generally brief, but total appointment time depends on assessment and the clinical findings. One session may be enough for some patients; others need reassessment of the result and further treatment. The number is not determined automatically from haemorrhoid grade alone.
7. When can activities be resumed?
Many patients resume everyday activities quickly, but timing and restrictions vary. After the procedure, advice may include moderate movement, regular bowel habits and avoiding straining, intense exercise or prolonged time on the toilet for the period specified by the doctor.
8. Does sclerotherapy replace surgery?
Not automatically. It is one of the available outpatient procedures and may avoid or delay surgery in suitable patients, but it is not appropriate for every form of haemorrhoidal disease. Marked prolapse, a substantial external component, associated conditions or a lack of response may make rubber band ligation, other proctological procedures or surgery preferable.
9. What are the limitations, adverse effects and risk of recurrence?
Pain or discomfort, tenesmus, minor bleeding, inflammation, thrombosis, ulceration or urinary problems may occur; more serious complications are less common. The disease may recur regardless of the technique used. Fibre, hydration, bowel regularity and less straining help control contributing factors but do not eliminate the risk entirely.
10. How do I access treatment at Centro Medico Gargano?
Book an initial consultation. The doctor reviews your medical history and symptoms and, when indicated, performs inspection, a digital rectal examination and anoscopy. If haemorrhoids do not adequately explain bleeding or other findings, appropriate further investigation is recommended before proceeding.

Scientific evidence
The 2024 American Society of Colon and Rectal Surgeons guidelines include sclerotherapy among outpatient procedures for haemorrhoidal disease. A systematic review and meta-analysis examined effectiveness, recurrence and complications of different sclerotherapy techniques. The evidence supports selective use without making sclerotherapy the required choice for every patient.
