Anal fissure

An anal fissure is a small tear of the skin around anus. It can occur when you pass particularly hard stools, have constipation or have just given birth. Anal fissures can be very painful and cause bleeding when you pass stools. The pain can be sharp when you have a bowel movement and deep burning for around an hour afterwards.

Usually anal fissures heal quickly on their own. If they become chronic and the tear lasts for six weeks, self-help recommendations and medications may help and if these don’t work then surgery may be advised.

The surgical procedure, called lateral sphincterotomy, is the most effective treatment for anal fissure. It’s a short operation taking approximately 15 minutes and involves making a small cut to the ring of muscle surrounding your anal canal to reduce the tension in your anal canal and allows your fissure to heal.

Anal fistula

An anal fistula is a small tunnel that develops between the skin around your anus and your back passage that often develops when an anal abscess doesn't heal properly after the pus has drained away.

An anal fistula causes a continual throbbing pain that can be worse when you sit down. You may experience swelling, redness and skin irritation around your anus and when you have a bowel movement you may pass puss or blood.

Surgery is normally advised for anal fistulas. There are a few options including a fistulotomy where the whole length of the fistula is cut open so that it can heal as a flat scar and seton procedures which leaves surgical thread called seton on the fistula for several weeks to help it heal. Non-surgical options include fibrin glue or a collagen plug and these seal and close the fistula tract.


Haemorrhoids, often called piles, are swollen veins and muscle around your rectum and anus. They are associated with an increase in pressure in these blood vessels possibly due to straining on the toilet. Often haemorrhoids don’t have any symptoms but they can sometimes be painful and itchy and may bleed if they become damaged.

Initially dietary changes, self-care measures and medicines will normally be recommended. If these aren’t successful, then banding and sclerotherapy may be advised if the haemorrhoids that are in the upper part of your anal canal.

Surgery may be the best option to treat your piles. There are many different types of surgery for haemorrhoids. They normally involve removing the haemorrhoids or reducing their blood supply so that they shrink.

At Winfield Hospital we use a minimally invasive surgical procedure, called the THD method, also called haemorrhoid ligation, haemorrhoidal artery ligation or Doppler guided ligation. A THD is performed under general anaesthetic and it reduces the blood flow to your haemorrhoids. A small ultrasound device called a Doppler probe identifies the blood supply for the haemorrhoids and then a stitch is placed in each artery to block the blood supply. THD is approved by NICE and designed to gently cure haemorrhoids and offers excellent long term results.

Hernia repairs

Hernias are bulges or swellings that happens when a part of your body pushes through a weakness in your muscle or surrounding tissue wall. They can appear anywhere on your body but are most often found between your chest and hips.

Common types of hernia include: inguinal and femoral hernias (fatty tissue or a part of your bowel pushes into your groin at the top of your inner thigh), umbilical hernias (fatty tissue or a part of your bowel pokes through your stomach near your navel) and hiatus hernias (part of your stomach pushes into your chest by squeezing through an opening in the diaphragm).

Hernias don’t always need surgery. If surgery is advised, then you may have an open procedure or keyhole/laparoscopic surgery with the decision being based on the severity of your hernia and where it’s located.  

We offer the advanced open mesh technique that involves positioning a piece of fine mesh at the opening of the hernia and allowing the body to heal naturally around it. It provides a successful repair carried out in minutes under local anaesthetic.

Lipoma removal

A lipoma is a soft, fatty, benign lump that appears under your skin due to an overgrowth of fat cells. A lipoma can grow anywhere in the body that has fat cells, often appearing on shoulders, neck, chest, back, bottom, thigh and arms.

If a lipoma is small and painless it can be left alone. Larger lipomas can cause embarrassment and self-consciousness. The NHS do not treat lipomas for aesthetic reasons. Winfield Hospital treats and removes lipomas for both aesthetic and medical reasons.

Removal of lumps and bumps

Lumps and bumps can appear in most areas of your body. Most lumps are harmless and known as benign lumps but it’s best to get them assessed by a consultant, for peace of mind to check that they’re not malignant, sooner rather than later.

Moles can develop in many shapes, sizes and colour variations. They are often harmless but if they do change colour, shape or irritate your skin then it’s best to seek immediate medical attention.

Lumps, bumps and moles are all skin lesions that aren’t routinely treated on the NHS for aesthetic purposes. Winfield Hospital understands they can be emotionally distressing and embarrassing and offers treatment of benign skin lesions for aesthetic purposes.

A skin lesion removal procedure is typically performed under local anaesthetic. Your consultant general surgeon will discuss your options and advise on the best choice for you, dependent upon the shape, size and location of your skin lesion.

Pilonidal sinus

A pilonidal sinus is an abnormal cavity in your skin that’s usually found at the top of your buttocks. It normally develops when hair punctures the skin and then becomes embedded. If a pilonidal sinus becomes infected it may lead to an abscess that can be very painful and surgery will probably be recommended.

Treatment options include draining the pilonidal sinus through a small incision, removing it surgically or, sealing it using fibrin glue.

Removal of gall bladder

The gallbladder is a small organ located in the upper right part of your stomach that connects your liver to your intestines by tubes called bile ducts. It collects and stores a liquid called bile, that helps your body to digest food. Your gallbladder isn’t essential to your body so if it becomes diseased, damaged or if you have gallstones then it’s removal is often recommended.

A gall bladder is most often removed due to painful gallstones. Gallstones are small stones in your gallbladder that may develop due to imbalances in your bile may up. They can cause severe stomach pain and discomfort, vomiting and jaundice. 

Gall bladder removal, medically called cholecystectomy, is performed under general anaesthetic. It’s most often undertaken using keyhole surgery although it can be done using open surgery.
