What are Haemorrhoids and methods of treatment

Haemorrhoids

What are Haemorrhoids?

Internal and External Hemorrhoids, Hemorrhoids enlarge image
Haemorrhoids are enlarged cushions around the back passage. These cushions are made up a complex of small arteries and veins which are important in preventing leakage from the anus.

Anatomically there are three cushions lying in the left lateral, right posterior and right anterior positions and can be shrunk by applying an elastic band 2 to 3 centimetres above the dentate line in the anus where there are no pain nerves. It is important to restore the cushions to normal size but not to remove them completely.

Causes

The cause of haemorrhoids is anything that increases intra-abdominal pressure over time such as constipation or diarrhea or obesity or heavy lifting.

Pregnancy is a good example of a short period of increased pressure, relieved when the baby is delivered and this type of haemorrhoid may not require any major treatment. Pregnancy is a good example of a short period of increased pressure, relieved when the baby is delivered and this type of haemorrhoid may not require any major treatment.
Lack of soluble fibre (e.g. bran), insufficient water, straining and sitting for a long time on the toilet are major factors in causing haemorrhoids and fissures and their complications.

Travel

It is important to recognize that airline travel and pressurized aircraft can give problems with upset bowels and haemorrhoid exacerbations. The best advice is to pack a whole-wheat sandwich to eat, avoid food and alcohol on the plane, drink as much water as you can from the service and supplement this with two litres of water you take on board the plane. Try to walk about as much as you can on the flight.

Natural History

Haemorrhoids get larger with time and may bleed or itch at the beginning but later come out transiently or even stay out all the time.

Skin tags can form on the outside and sometimes the haemorrhoids can thrombose and become very painful. When there are large tags it may be difficult to keep the area clean and there may be a discharge and itch or irritation.

After the age of 50 years 50% of people will have haemorrhoids but only 1% will need treatment each year. 97% are treated with banding.

Methods of Treatment

The best treatment is prevention by taking enough dietary fibre (2 tablespoons of bran, Metamucil or Benefibre, ground flax, ground chia seeds or inulin-chicory root) and 7 to 8 glasses of water per day and not being overweight and taking The best treatment for haemorrhoids is prevention by taking enough dietary fibresome exercise. With the development of early haemorrhoids this is usually still the best way to manage the problem and the addition of a cream (no difference between most of the emollient creams, so go cheap) is usually sufficient. The use of a steroid cream or analgesic ointment should generally not be used for longer than a week. An important change that will help is not spending longer than 2 minutes on the toilet to have a bowel movement, and going back a few hours later if you cannot have a bowel movement then.

If this does not work, you will likely be sent to a specialist who will, first of all, make sure that haemorrhoids are the only problem. Other causes such as inflammatory bowel disease, fissure or even bowel cancer will need to be ruled out if there is a family history of cancer, weight loss, blood mixed in with the stool or a lot of pain.

Usually you will have a digital rectal exam and proctoscopy but a sigmoidoscopy or colonoscopy may be needed depending on the risk factors. Although Laser, injection of sclerosant, or infrared are used for a few patients, the vast majority of haemorrhoids are treated by rubber band ligation since the 1960's. A few patients with very advanced haemorrhoids (grade 4) may require surgery because of the large amount of haemorrhoid protruding through the anus, but it is still often worth trying ligation because it is so much better accepted by the patient, and the external lump(s) may shrink by as much as 80%.

Because of the issues related to sterilization of instruments between cases and the risk of cross infection there is a need for a disposable ligator. The advent of HIV, the recognition of the highly infectious Hepatitis B and C have made patients and health professionals switch to disposables whenever feasible for other procedures. The advent of the Medsurge proctoscope and bander (Reagan) makes this possible now for haemorrhoids.

Procedure

CRH-O’Regan Disposable Hemorrhoid Banding SystemThe patient is informed of the steps in the procedure, and placed on a couch on the left side with only the anal area exposed. The surgeon is gloved.

He performs a digital exam and then directs the lubricated proctoscope into the anus pointing it towards the umbilicus first and then after three centimeters, backwards and inserts the proctoscope fully and then removes the obturator. With the aid of a bright wall or floor lamp the three haemorrhoidal masses are identified and the internal foramen turned towards each in turn starting with the left, then the right anterior then the right posterior. If this is at the right point (1 to 2 cms above the dentate line) the patient will have no pain and the barrel of the syringe can be locked and the band fired onto the pedicle. The ligator is left for some time to suck in tissue. Otherwise, if there is discomfort, the vacuum is released and the tip of the syringe applied higher up.

Usually only one band is performed at each visit as it has been shown that multiple ligations have more complications.

The technique of sucking the right part of the haemorrhoid and locking the syringe requires some practice, and can be done with one hand without repositioning the fingers or with one hand locking the barrel with the thumb and repositioning the fingers for the final locking movement. There is a feeling of fullness and slight discomfort but pain is rare. If pain occurs it comes on immediately and can be quickly relieved on the spot by moving the band a little with a gloved finger. The haemorrhoids can be done one at a time and repeated in the order noted at weekly intervals until all three are done.

Following the procedure the patient should take a high fibre diet and 7 to 8 glasses of water to avoid constipation. Painkillers are not required. The patient may feel a fullness of the rectal area for up to 24 hours.

Complications are extremely rare (less than 0.3% of procedures) and include bleeding, dicomfort and swelling. The more serious side effects of difficulty in passing urine and - more rarely still – bacteraemia have not been seen so far in 20,000 procedures.

The patient should be seen and re-examined in three or four weeks.

Commonly Asked Questions

If I have a lot of pain from haemorrhoids or fissure what should I do?

A: Haemorrhoids are painful if they stick out and the blood in them becomes clotted (thrombosed). Lying flat or having a warm bath with a tablespoon of salt in the water is helpful.

Do not take painkillers with codeine in them as these cause constipation and makes things worse. Fissure pain responds to the same routine and is much the commoner source of pain.

If I get bleeding from Haemorrhoids, what should I do?

A: You should lie flat with your bottom a little higher than your head. The reason for this is that the bleeding is usually form the veins and walking, sitting on the toilet etc just increases the pressure and makes the bleeding worse. An ice pack applied to the anal area also helps.

If the bleeding is more than a pint contact your doctor or go to the nearest emergency. Remember that blood loss looks more than it is when it is in the toilet.
