Although the gallbladder is very important, it is necessary to remove the gallbladder if it is seriously diseased, otherwise it can lead to more serious lesions.

One of the "bad gallbladders": gallbladders that have had repeated attacks of cholecystitis
The majority of cholecystitis attacks are caused by the presence of gallbladder stones that block the exit of the gallbladder, causing the bile in the gallbladder to be unable to be discharged smoothly, and "suffocating" the gallbladder, resulting in cholecystitis.
Regardless of whether there is no stone, repeated attacks of cholecystitis stones are not to be, because cholecystitis repeated attacks, to reduce the attacks need to eat less greasy, repeated attacks of gallbladder inflammation leads to gradual thickening of the wall of the gallbladder, coupled with repeated rubbing of stones on the wall of the gallbladder, which will increase the incidence of gallbladder cancer.

"Gallbladder that may cause or has caused bile duct stones

As mentioned above, cholecystitis occurs when stones block the exit of the gallbladder. These stones are relatively large, while smaller stones can flow out of the gallbladder smoothly and then block the common bile duct. At this point, neither the bile secreted by the liver nor the bile stored in the gallbladder can flow into the small intestine, and then it enters the bloodstream through the tiny bile ducts in the liver, resulting in a yellowing of the skin and eyes all over the body, which is called "obstructive jaundice".

"Gallbladder that may cause or have caused biliary pancreatitis

Large stones block the exit of the gallbladder, smaller stones block the common bile duct, and what about smaller stones? Such stones are called "sediment stones" and they can reach the opening of the common bile duct, which is in the duodenum, right next to the opening of the pancreatic duct, so these very small stones can enter the pancreatic duct even more smoothly. So, these very small stones can enter the pancreatic duct more "smoothly", inducing "biliary pancreatitis", it is obvious that this kind of silt-like stones gallbladder is even more undesirable.

The fourth of "gallbladder of no use": non-functional gallbladder
Although some patients have not had cholecystitis attacks, but the gallbladder is full of stones (full stones), bile is little or almost no; or due to excessive growth and thickening of the gallbladder wall, resulting in the gallbladder cavity almost disappeared (gallbladder adenomyosis).

"Gallbladder with Polyps
Not all gallbladder polyps require removal of the gallbladder. Multiple polyps in the gallbladder, single polyps less than 1cm in diameter, and a tibia are often indicative of benign lesions, and regular review of abdominal ultrasound is sufficient.

The sixth of the "gallbladder": highly suspicious of malignant changes in the gallbladder
This should not need to be said, for suspected or determined to be malignant gallbladder lesions, if the situation permits, of course, "can be cut on cut".
