In early disease, the priority is soft, formed stool without straining: a fibre-rich diet, adequate fluid intake, physical activity and treatment of constipation or chronic diarrhoea. Ointments or suppositories may provide short-term relief but do not correct the anatomical cause of advanced disease.

Rubber-band ligation places a small band over internal haemorrhoidal tissue so that it regresses. It is established particularly for symptomatic grade I and II disease and selected grade III cases. Sclerotherapy or infrared coagulation may also be considered depending on the findings.

Marked prolapse, larger external components or advanced disease may require haemorrhoidectomy. Targeted removal of enlarged nodules is highly effective and an established standard for advanced findings. Haemorrhoidal artery ligation closes supplying vessels and may be combined with mucopexy for mucosal prolapse; potentially less postoperative pain must be weighed against a higher recurrence risk depending on the initial findings.

Laser haemorrhoidoplasty (LHP) introduces a fine laser fibre into the enlarged cushion. Controlled energy coagulates and reduces the tissue. In selected grade II and III disease, studies show advantages in early pain, blood loss and recovery. Long-term evidence and recurrence outcomes are less consistent; LHP is a selective option, not inherently superior.

Complete prevention is not always possible. Good long-term stool regulation, a fibre-rich diet, adequate fluid intake, regular activity, short toilet visits and avoiding straining can reduce symptoms and renewed stress.

A fully developed anal abscess generally cannot be cured with ointments or antibiotics alone. The key treatment is prompt surgical opening and adequate drainage. Antibiotics may be added for certain risks or systemic signs of infection, but do not replace drainage.

If a fistula is identified at the same time, further treatment depends on its course and sphincter involvement. Preserving sphincter function and continence is especially important. No reliable primary prevention is known; recurrent abscesses should prompt a targeted search for a fistula or underlying disease.

In addition to cryptoglandular fistulas, causes may include Crohn’s disease, previous surgery, injury or other conditions. Crohn-associated fistulas are often managed through interdisciplinary care. For surgical planning, the relationship to the sphincter is decisive: the more sphincter tissue involved, the more important a sphincter-preserving approach becomes.

A persistent cryptoglandular fistula usually does not heal reliably with medication alone. Acute infection may first require drainage or a seton. Superficial, low fistulas can be treated very effectively by fistulotomy provided there is no unacceptable continence risk. Higher or complex fistulas may be treated with advancement flap, LIFT, selected seton strategies, TROPIS, or endoscopic and laser-based procedures.

VAAFT is a video-assisted, sphincter-preserving procedure. A thin fistuloscope is introduced through the external opening, allowing direct visualisation, irrigation and removal or coagulation of inflammatory tissue. Side branches can be identified and the internal opening treated or closed according to the findings.

Its advantage is direct endoscopic visualisation while largely preserving the sphincter. Evidence remains heterogeneous. VAAFT is a selective option, not a universal standard for every anal fistula.

FiLaC introduces a radially emitting laser fibre into the fistula tract. During controlled withdrawal, the tract wall is coagulated and contracted from within without dividing the sphincter. Healing rates vary and high-quality long-term data remain limited. FiLaC is therefore selected only after careful assessment of fistula anatomy.

No reliable primary prevention is known for cryptoglandular fistulas. Important measures include early treatment of an anal abscess, investigation of recurrent abscesses, treatment of underlying disease and consistent follow-up after surgery.

The priority is consistently soft stool through fibre, fluids, avoidance of straining and medication for stool regulation when needed. Warm sitz baths may relieve symptoms. In chronic fissures, topical nitrates or calcium-channel blockers such as diltiazem or nifedipine may reduce internal sphincter tension.

Botulinum toxin injection can temporarily reduce muscle tension and support blood flow and healing, particularly after insufficient response to topical therapy. Lateral internal sphincterotomy is highly effective for chronic treatment-resistant fissures. Because sphincter surgery may affect continence, careful patient selection and alternative procedures where appropriate are essential.

Normal, soft stool without straining is key. Adequate fibre and fluids, together with early treatment of constipation or persistent diarrhoea, can help prevent renewed mechanical injury.

An asymptomatic finding does not require prophylactic surgery. An acute abscess requires surgical drainage, which should not be delayed by antibiotics. In chronic symptomatic disease, treatment depends on extent, number of openings, previous operations and individual factors.

Limited disease may be suitable for pit picking, sinusectomy, endoscopic treatment or laser ablation. More extensive or recurrent disease may be better managed in the long term with larger off-midline procedures.

EPSiT introduces a thin endoscope through a small opening into the sinus system. Under direct vision, the tract and branches are assessed, hair and foreign material are removed, and inflammatory tissue is cleared or coagulated. The aim is small access points and limited tissue damage. Long-term evidence remains limited, and patient selection is crucial.

SiLaC involves careful cleaning of the tract system followed by internal coagulation using a radially emitting laser fibre. Small skin openings and a limited wound area are potential advantages. Long-term comparative data remain limited, and laser treatment does not inherently replace larger operations in extensive or recurrent disease.

No single preventive measure has proven universally effective. Good local hygiene, reduction of modifiable risk factors and early assessment of new symptoms are reasonable. Routine hair removal is not required for everyone and should be discussed individually.
