The gallbladder stores bile, a digestive enzyme liquid, that is constantly produced by the liver. After meals, stomach hormones make the gallbladder contract and squeeze the bile down the bile duct and out into the duodenum (upper bowel) to help in digestion of fat and protein in foods. All gallbladder diseases (gallstones, sludge, polyps and adenomyomatosis (gallbladder wall thickening) are mostly a consequence of western diet and lifestyle factors.
Gallstones are small (few millimetres to a few centimetres) lumps that form in our gallbladders, usually as a result of precipitation of dietary cholesterol. Sludge is simply the earlier stage of gallstone development, but can also cause symptoms. Gallbladder polyps are growths arising from the gallbladder wall, and can also cause gallbladder symptoms.
Gallbladder disease is very common, affecting 15-20% of the population. Most people with gallbladder disease will have no symptoms. Once gallstones, polyps, etc become symptomatic, all guidelines suggest your gallbladder should be removed, as the risks of surgery are less than the risks of developing progressive and more serious problems from your gallbladder.
These international consensus guidelines take into account the fact that, in the hands of well trained and safe surgeons, laparoscopic cholecystectomy is now extremely safe.
Gallstones, gallbladder polyps, etc, in westernised countries like Australia, probably form as a result of chronic inflammation and cholesterol from our diets.
Gallstones can cause the following symptoms:
If you are diagnosed with a gastric GIST, the next step is to ‘stage’ the tumour. This involves further scans (CT scan) to better define whether or not the tumour has spread.
Gallbladder polyps can develop into gallbladder cancer, for which the prognosis is often poor. This is why gallbladder polyps need to be watched very carefully, with a low threshold for gallbladder removal (cholecystectomy). Guidelines suggest your gallbladder should be removed if you have gallbladder polyps larger than 6mm in diameter, multiple polyps, associated gallbladder symptoms, are female, aged over 50 or of Indian ethnicity. These are all risk factors for progression to gallbladder cancer.
Gallstones are diagnosed by a simple and painless ultrasound scan. More advanced testing (MRCP, a type of MRI scan) may occasionally be necessary during treatment for gallstone problems. Bloods tests will also be required (Liver Functions Tests, to look for bile duct blockage and occasionally Lipase, to look for pancreatitis). Ultrasound, however, does not reliably distinguish between gallstones, polyps, sludge and adenomyomatosis.
Once gallstones or gallbladder polyps are diagnosed, Dr Ben will take a thorough history of your symptoms. If there is a strong connection between your symptoms and your gallstones or gallbladder polyps, Dr Dodd will likely recommend laparoscopic cholecystectomy (keyhole removal of your gallbladder), usually done as a day case.
