Fixing those fissures

By Esther Williams

Embarrassing though they may be, fissures, fistulas and haemorrhoids need to be treated. "As there is bleeding in each of the conditions, patients need to assure themselves that it is not due to something more sinister like cancer," explains Consultant Surgeon from the University of Kelaniya, Prof. Kemal Deen.
Fissures: An anal fissure is a tear in the skin around the opening of the anus that can cause intense pain, especially when opening the bowels. A common occurrence among young and middle-aged men and women in Sri Lanka, fissures are seen more often in those who are stressed.

The wound that occurs in the posterior anal passage is temporary and will heal automatically in 7-10 days if you do nothing. However the pain is severe especially during or after a bowel movement most often accompanied by bleeding.

Although the exact cause is unknown, fissures that are easily confused with haemorrhoids are caused due to the lack of nitric oxide in the muscles surrounding the anal passage. According to Prof. Deen, it causes the sphincter muscle to contract tightly, restricting blood supply and oxygen to the lining causing a longitudinal split or ulcer that results in a fissure.
Fissures are also linked to constipation where straining on hard or large stools can tear the skin of the anus.

For acute or first time fissures, treatment includes medication to relieve patients of pain. This may come in the form of local aesthetic gels/paste or painkillers (tablet or local application). Laxatives are recommended for soft bowel movement and sitting in a warm bath of water to relieve spasms in the sphincter. Occasionally doctors recommend the use of a nitric oxide donor agent called GTN (Glyceryl Tri Nitrate) paste. This, however, is not popular as it can cause intense headaches.

The professor is emphatic about the significant role diet plays in treatment of fissures. A diet rich in fibre, laxative fruits such as sour bananas, papaya, prunes and raisins and at least 1 ½ litres of water is suggested in the bowel management programme he recommends.
Should patients with chronic anal fissures find little relief from a bowel management programme, surgery (under local anaesthesia) becomes imperative especially if the patient's quality of life is impaired and if the recurrent spells are frequent. The aim of surgery is similar to that of medicines - to relieve excessive pressure within the anal canal. This, however, is the last resort.
Fissures cannot be prevented but can be stopped from getting worse through diet. While stress can make the condition worse, spicy food can make the bowel movement painful.

Fistulas: More common in Eastern people a fistula occurs when there is an abnormal connection between the anal canal and the superficial peri-anal skin. When this happens the anal glands get infected and pus accumulates forming painful discharging wounds that recur frequently around the anus.
Dr. Sanjay Abeygunawardena, (Department of Surgery, University of Kelaniya) advises surgical intervention through spinal or general anaesthesia for this condition. The length of hospital stay depends on the complexity of the fistula. The first step in treating a fistula is an examination by a doctor to determine the extent and "path" that the fistula takes through the tissue.

The surgery, thereafter, assures adequate drainage of pus from the fistula (so that pus may escape without forming an abscess) followed by a procedure where healthy tissue is pulled over the internal side of the fistula to keep faeces or other material from re-infecting the channel. Patients are then educated to manage the wound until it heals. Similar diet and lifestyle changes recommended for fissures apply here.

Haemorrhoids (piles) that can occur at any age are more common in middle-aged women. Although it can be a hereditary tendency, poor toilet and dietary habits, both of which are controllable are the main causes for haemorrhoids. Senior Lecturer, University of Kelaniya (Department of Surgery), Dr. S. Kumarage points out that everyone has vascular cushions within the anal passage that have the important function of controlling bowel continence. These cushions close the anal passage when not in use. However due to poor bowel habits, they can get dragged down, losing their normal function. Sufferers may experience bleeding, discomfort, obstruction or lump in the passage.

"It is important to note that haemorrhoids are benign and will never become cancerous, Dr. Kumarage stresses. However it is important that patients are checked to ensure that what they suffer from is not a cancer. "If disregarded, you may miss a cancer in the early stage," he adds.
Haemorrhoids can be at various stages: when they are bleeding but inside the anal passage; when they come out but go back in and when they stay out, all of which can cause irritation, itching, bleeding and discomfort. If neglected, haemorrhoids can get strangled causing swelling and pain.

Once cancer is ruled out, treatment includes advice on diet and toilet habits. In order to keep stools soft and bulky, an ideal form for easy defecation, patients are asked to drink plenty of water, consume fibrous foods (fruit and green vegetables) and cut down on refined sugar. As for toilet habits, the doctor says that patients should not postpone the task. Rather than read or listen to music which makes them strain, they should simply finish the job and come out. Fortunately, early haemorrhoids can be controlled. However if bleeding is significant causing severe discomfort despite following the dietary measures, doctors may opt to inject a drug to make the haemorrhoids less prominent (shrink). Alternatively they can band them with a latex free rubber which also will ensure that they shrink and disappear. If the problem is not settled with this, haemorrhoids may have to be surgically removed as a last resort.

Dr. Kumarage says the latest surgical treatment that fixes haemorrhoids in their normal position (Haemorrhoid-pexy) is not favoured here owing to its cost. However, it is reported to be effective and less painful thereby enabling the patient to resume work faster.
