Appendicectomy

Before you agree to have your appendix removal operation it is important to know all you can about it. The information here is a guide to common medical practice. Each hospital and doctor will have slightly different ways of doing things, so you should follow their guidance where it is different from the information given here. Because all patients, conditions and treatments vary it cannot cover everything. Use this information when making your treatment choices with your doctors. You should mention any worries you have. Remember that you can ask for more information at any time.

 

 

You have pain in your abdomen. You may also feel nauseous or be vomiting. We think your appendix may be the cause of your problems.

 

The appendix dangles from the bowel in the right hand side of your abdomen, like the finger of a glove. It is of no use to humans, but is important in grass eating animals.

 

The appendix commonly gets infected. This causes cramping pains in the centre of the abdomen, often with vomiting. The appendix then swells; this is called appendicitis. It then irritates the overlying abdominal wall, giving pain around the umbilicus and in the right side of the abdomen.

If untreated, the appendix may burst inside the abdomen or form an abscess. Sometimes a slightly infected appendix will settle down by itself over three or four days or so.

 

The aim is to take out the infected appendix before it can cause serious damage. This operation is called an appendicectomy.

 

There are two possible operations to remove the appendix. Sometimes an open appendicectomy operation will be done. Other times laparoscopic surgery is done instead, with three or four tiny cuts in the lower abdominal wall and around the umbilicus. The choice is normally on a case-by-case basis and the experience or preference of the surgeon.

 

You should safely and quickly return to normal health. There would be no risk of appendicitis again. If there is another surgical cause for your pains, we can deal with that straight away while you are still under the anaesthetic.  

 

The traditional operation for appendicitis is the open appendicectomy. Recently, laparoscopic surgery has become more common and laparoscopic appendicectomy is becoming routine. But laparoscopic surgery is not possible in all cases. You should discuss the type of operation to be done with your surgeon. Laparoscopic appendicectomy has a number of advantages over the open operation, namely:

 

 

The main disadvantage is that the operation takes longer than a straightforward open operation.

 

There is no x-ray or laser treatment. An ultrasound scan of the abdomen is helpful in pointing to diseases in the ovaries or Fallopian tubes, but it cannot rule out appendicitis. There are no blood tests to find out whether you have appendicitis.

 

If appendicitis is not clearly the cause of your pains, waiting to see if you get better over six hours or so is reasonable. Antibiotics and painkillers during this time are helpful. 

 

There are many conditions that appear like appendicitis. Some can lead to serious illness if not operated on. They include cysts of the ovary, Meckel's diverticulitis, or even bowel cancer in an older person. Other conditions, such as virus infections of the nearby glands or bleeding into the ovary, settle down without surgery.  Sometimes nothing abnormal is found, suggesting that the pains were a simple bowel cramp or colic.

 

If your appendix is infected and takes its natural course, you may become very ill and even die. We cannot be sure about the cause of your pains until we look inside your abdomen. The chance of finding nothing serious is about one in 10. However, it is safer to do the operation than to risk the problems of missing an infected appendix or other condition needing surgery.
