During gallbladder surgery, the gallbladder is removed from its attachments to the liver and bile duct and is extracted from the body. The procedure is usually performed under general anaesthesia with laparoscopic (keyhole) surgery, either as a day-case procedure or sometimes as an overnight stay.
Here to provide an expert insight into gallbladder surgery is Mr Jonathan Wilson, leading consultant in general and colorectal surgery based in London.
Why does a gallbladder need to be removed?
Once gallstones have started to form in the gallbladder, it is likely that the gallbladder is no longer functioning properly and therefore is not providing a physiological role anymore. The key decision when patients are first referred to the specialist is in determining whether the symptoms are really due to the stones, and not something unrelated such as peptic ulcer disease or irritable bowel syndrome (IBS).
Up to one out of three patients may have incidental gallstones found during an investigation, but in the majority of these patients, the stones will be innocent bystanders and the symptoms due to a separate pathology. However, if the symptoms are thought to be due to gallstones, and the stones and gallbladder are left there, they will continue to cause symptoms, which range from indigestion to severe upper abdominal pain, requiring hospitalisation. In their extreme, stones can cause pancreatitis which can be life-threatening.
What is the procedure during gallbladder surgery?
On average, 95 per cent of cases are done with laparoscopic surgery and using four tiny cuts, with the largest being 10mm. The gallbladder is freed from it its attachments from the liver and bile duct, and extracted in a bag via the umbilical (belly button) cut. This is either as a day-case procedure or sometimes an overnight stay, with a further one to two weeks off work recovering.
In less than five per cent of cases, keyhole surgery is not enough and traditional 'open' surgery is necessary (only decided during the general anaesthetic) with a 10 - 15 cm cut below the right rib cage. This is much more painful to recover from and requires three to five days in hospital with another two to three weeks off work, so it's clear there is a big difference between keyhole and open surgery.
What’s life like post-operation?
Knowing which patients with gallstones will benefit from surgery is a key decision, and thus, excluding an alternative cause for pain is crucial. Clearly if the patient’s symptoms were actually due to indigestion, IBS or an alternative pathology, then their symptoms will remain post-operatively.
There is also a condition called Post-Cholecystectomy Syndrome (PCS) which describes a range of symptoms from abdominal pain, nausea/vomiting, change in bowel habit to looser stool, etc. It can affect 10 - 15 per cent of patients undergoing cholecystectomy (surgical removal of the gallbladder).
The symptoms can either be the original ones which have never gone away, usually because the gallstones were never genuinely responsible for the symptoms in the first place, or come on for the first time post-operatively as a consequence of surgery. Part of the consultation with a specialist will weigh up the risks versus benefit with the patient, whilst putting risks into real perspective.
