Gallstones, unfortunately, don’t go away on their own and if they are persistent and causing discomfort, your surgeon will likely decide that you need to have your gallbladder removed.

 

Mr Radu Mihai is an expert consultant surgeon specialising in treating gallstones. He explained to us what gallbladder removal surgery involves and the risks and complications you might experience following the procedure.

 

 

How are gallstones diagnosed?

When the history of symptoms suggests biliary colic, the first step is to demonstrate the presence of gallstones using abdominal ultrasound. Blood tests will aim to exclude associated infection or jaundice.

 

Magnetic resonance cholangiopancreatography (MRCP) is used if the ultrasound suggests an enlarged bile duct or if the blood tests show abnormal liver function tests. As you can see below, MRCP image provides the most accurate 3D reconstruction of the gallbladder and its surrounding structures.

 

Once a decision to proceed with the surgery is secured and an admission date is confirmed, you should:

  • Stop all blood-thinning medication several days before the operation (discuss with your surgeon the timing of this change in medication)
  • Continue to take all your drugs, such as those for blood pressure or control of diabetes
  • Eat nothing the night before your surgery. You may drink a sip of water with your medications, but avoid eating and drinking at least four hours before your surgery

 

How is the surgery performed?

The key-hole approach, known as laparoscopic cholecystectomy, is the standard procedure for the vast majority of patients. Exceptions are rare, such as patients with multiple abdominal operations. The majority of elective patients, however, are suitable for day-case surgery.

 

At present, there is no evidence to show any benefits from performing single incision laparoscopic surgery (SILS), natural orifice transluminal endoscopic surgery (NOTES) or robotic surgery. Compared with open surgery, laparoscopic cholecystectomy is associated with reduced pain, better cosmesis, early recovery and early return to work and therefore this is the gold standard treatment of gallstones.

 

The operation starts with a small 2cm incision under the umbilicus through which a camera is introduced in the abdominal cavity. Under vision, three trocars are introduced under the rib cage through small 5-10 mm incisions. The operation relies on safe demonstration of the anatomy of the bile duct and its connection to the gallbladder. Clips are applied across the cystic duct and artery and the gallbladder is ‘lifted’ from its liver bed. The gallbladder (and the stones contained within it) are placed into a retrieval bag that is removed through the umbilical port. After a final inspection of the abdominal cavity, the ports are closed with resorbable stitches.

 

The skin incisions are stitched together with absorbable material. Skin glue is then applied to create a ‘seal’ that allows you to shower without worrying about getting the dressings wet.

 

What are the risks and potential complications?

Every operation carries risks, but all care is taken to mitigate them. A recent landmark court case introduced the Montgomery principle, whereby during consent, the medical professional should inform the patient about all risks, irrespective of how small the chances are of them occurring if they could be related to a life-changing event.

 

The risk of complications after laparoscopic cholecystectomy include:

 


Common problems  

 


Rare problems (1% risk)

 


Exceedingly rare problems

 

  • Mild shoulder pain (from the carbon dioxide gas).
  • Infection. Some people develop a wound or internal infection after gallbladder removal. Signs of a possible infection include increasing pain, swelling or redness, and pus leaking from a wound. See your GP if you develop these symptoms as you may need a short course of antibiotics.
     
  • Bleeding. Bleeding can occur after your operation and may require a further operation to stop it.
  • Bile leak. Bile fluid can occasionally leak out into the tummy (abdomen) after the gallbladder is removed. Occasionally, a further operation is required to drain the bile and wash out the inside of your tummy.
  • Deep vein thrombosis (DVT). Some people are at a higher risk of developing blood clots in a leg vein after surgery. If such a clot is dislodged from the leg it could block the flow of blood into the lungs (pulmonary embolism) – a very dangerous medical condition.You will need to wear special compression stockings during and immediately after the operation and use special pumps to squeeze your calf muscles during the operation. Both these ‘mechanical’ methods are used to decrease the risk of DVT. In addition, you might receive an injection of a drug to thin your blood.
  • Injury to the bile duct. The bile duct can be damaged during gallbladder removal. If this happens during surgery, it may be possible to repair it straight away. In some cases, further surgery is needed after your original operation.
  • Injury to the bowel and blood vessels. The surgical instruments used to remove the gallbladder can also injure surrounding structures in the abdomen.
  • Risks from general anaesthetia are very rare. Allergic reaction and death can potentially occur after any operation. Being fit and healthy before your operation reduces the risk of such complications.

 

Post-cholecystectomy syndrome

After the operation, around 5% of patients experience symptoms similar to those caused by gallstones before the operation (pain, indigestion) or develop new symptoms attributed to the gallbladder (gastritis, diarrhoea). This problem is supposed to be caused by changes in bile flow after the removal of the gallbladder. If symptoms persist for more than 3-6 months after the operation, you should seek advice from a gastroenterologist.

 

What is the short-term and long-term aftercare like?

Your operation will be organised as a day-case or with an overnight admission in the hospital. You will receive painkillers to help control the mild abdominal pain you are expected to experience. You should be able to mobilise to the toilet within a few hours after the operation.

 

If you are going home on the same day, in the following 24 hours you should: • drink plenty of fluids, follow a light diet and avoid alcohol • not be left alone in the house • not operate machinery or home appliances – e.g. cooker, kettle, etc.

 

In the coming days, it is important to move around the house regularly but avoid strenuous exercise. Normal activities may be resumed in approximately 1 week but do not do any heavy lifting for at least 2 weeks. Intense gym exercise, such as weight training would be best delayed for 6 weeks.

 

Additionally, after the operation, you shouldn’t drive until you are comfortable enough to be able to make an emergency stop. This could take at least 1 week but will more likely take 2 weeks. You should check with your insurance if they have strict rules about this scenario.
