The colorectal department at London Bridge Hospital focuses on lower digestive tract diseases, which can affect your colon, rectum, anus and pelvic floor. We can diagnose and treat a range of these diseases, such as Colon Cancer and Crohn’s Disease.

Minor outpatient procedures, such as endoscopies and colonoscopies, are carried out at The Shard. More complex treatments are carried out at other HCA Healthcare sites after diagnosis.

Colorectal procedures at London Bridge Hospital

Upper GI endoscopy

This examination involves passing a small, fibreoptic tube (the endoscope) through the mouth into the stomach. This allows the doctor to look directly at the lining of the oesophagus (gullet), stomach and duodenum (the first section of the small intestine). If a sample of tissue needs to be taken for analysis (a biopsy), it will be removed painlessly through the endoscope, using miniature forceps.

Flexible sigmoidoscopy

This examination involves a fibre-optic camera examination of the rectum, sigmoid and left colon. Often performed without sedation, a flexible sigmoidoscopy is commonly used to look for bleeding or noncancerous growths (polyps) and is one of the main screening tests for colorectal cancer.


A colonoscopy involves a long, flexible tube about the thickness of a finger (the colonoscope) being inserted into the rectum and gradually advanced through the colon. This allows the physician to examine the lining of the rectum, diagnose colon and rectal problems, perform biopsies and remove noncancerous growths (polyps).


Proctology is the medical speciality that deals with the diagnosis and treatment of disorders affecting the colon, rectum and anus.

Banding of haemorrhoids

This outpatient procedure involves the surgeon taking hold of the haemorrhoid with forceps or a suction device and placing a rubber band around the base of the haemorrhoid. This cuts off the blood supply and causes the haemorrhoid to wither and drop off after a few days.

Stapled haemorrhoidectomy

A new technique for treating haemorrhoids, this removes the excess lining of the bowel, raising the haemorrhoidal tissue back to its regular position. This reduces the blood supply to the haemorrhoids, causing them to shrink. The procedure is relatively painless and can be performed as a day case in most instances.

Diathermy haemorrhoidectomy

This is the surgical removal of haemorrhoids, where the anal cushions are excised using diathermy – a high frequency electric current to produce heat. This is usually performed as a day case procedure in most instances.

Pilonidal sinus surgery for primary and recurrent disease

This procedure treats ingrowing hair follicles at the base of the spine. Hairs grow inwards through tiny holes in the skin (sinuses) where the germs on the hairs can cause pain, swelling and discharge. Surgical techniques include excision, Bascom's procedure and Limberg flaps.

Anal fissures

An anal fissure is a small tear in the skin, just inside the anus, usually towards the back. Treatments include the use of GTN (a drug used to relax the internal anal sphincter) or a sphincterotomy, which involves cutting out that part of the internal sphincter to relieve tension.

A similar effect to the sphincterotomy can be achieved using non-surgical methods, such as diltiazem for a chemical sphincterotomy and botulinum toxin (BOTOX®). A Botox fissurectomy lasts approximately three months, until the nerve endings regenerate. This three-month period may allow acute fissures to heal – if not, a surgical sphincterotomy may be recommended.

Perianal abscess and anal fistula surgery

A perianal abscess is a gathering of pus that forms next to the anus, often causing swelling and pain. An anal fistula is a narrow channel running from the skin near the anus to further up the anus, often occurring after there has been an abscess in the area. Surgery to treat these problems can involve draining the sepsis, the laying open of the fistula, seton insertion and rectal advancement flaps treatment.

Inflammatory bowel disease

Inflammatory bowel disease is a chronic condition in which the lining of the digestive tract becomes inflamed and covered with ulcers. Two common types of inflammatory bowel disease are Crohn's Disease and ulcerative colitis.

Surgery for Crohn's Disease

Crohn’s Disease can occur along the entire digestive tract and spread deep into the bowel wall. Although surgery can relieve the symptoms of Crohn’s Disease, it cannot cure it. Surgery may involve the resection of diseased segments of Crohn's and strictureplasty of short strictures to preserve bowel length. Some cases are done laproscopically, involving minimally-invasive surgery and micro-video cameras.

Pouch surgery for ulcerative colitis

Ulcerative colitis typically affects the top layer of the large intestine (the colon) and rectum. Pouch surgery involves taking the very end of the small intestine (the ileum) and creating a pouch that is then connected to the anus to allow waste to leave the body through the anus.

Colorectal cancer surgery

Although harmless in themselves, if non-cancerous growths (polyps) continue to grow, they may develop into a cancerous tumour. If this occurs, colorectal surgery may be necessary to treat the subsequent colon and rectal cancer.

Primary colorectal cancer surgery

This form of surgery includes all colonic and rectal resections, including low anterior resection of the rectum (where the tumour is removed without affecting the anus), and abdominoperineal excision (where the rectum and anus are both removed), with myocutaneous flap repair of the perineum. Some cases are performed laparoscopically, involving minimally invasive surgery and micro-video cameras.

Recurrent rectal cancer surgery

This form of surgery can involve multivisceral resection (surgery involving numerous organs). This includes total pelvic exenteration, which is the removal of the bladder, urethra, rectum, anus and supporting muscles and ligaments, together with the reproductive organs, as well as abdominosacral resection, which treats mid rectal cancer while preserving the function of the anal sphincter.

Rectal prolapse surgery

When the lining of the rectum collapses through the anal opening, surgery may be necessary to repair the prolapse. Our surgical team can provide perineal and abdominal surgical repair of full thickness rectal prolapse.

Rectocele repair

A rectocele repair procedure involves restoring the supportive tissue between the vagina and rectum to treat a prolapse of the rectum through the vaginal wall. In some cases, the surgery may be performed laparoscopically, involving minimally invasive surgery and micro-video cameras.

Anal sphincter repair

Damage to the anal sphincter is a relatively common problem, occurring in up to a third of women at their first vaginal childbirth. Subsequent problems can include faecal incontinence. This surgical procedure repairs the anal sphincter, so that it functions as normal.

Diverticular Resection

Consisting of the herniation of mucosa through the thickened colonic muscle, the number of diverticula can vary from one to many hundreds. Diverticular resection is used to treat complicated diverticular diseases, such as colovaginal (where stools are passed via the vagina) and colovesical fistulae (where the urinary bladder and the bowel become connected).
