As a professional technician, you are exposed to the same things every day, facing either the liver or the gallbladder, or the intestinal canal or something like that. These terms are familiar as if they are already an integral part of the body. It is true that the organs represented by these terms are also an inseparable part of the body. So one day, when I told someone I was a surgeon, the most common thing I removed was the gallbladder. The person asked me, “What is a gallbladder? That’s when I did stay for a moment, though maybe only for a second or two. I did some serious science. The gallbladder is an organ of the body, located in the upper right abdomen, and is closely related to the liver. It is an organ that is prone to disease, and most of the causes of disease and diet-related, usually after a large meal or a few years after not eating breakfast one day stomach pain, ultrasound cholecystitis gallstones, may need surgery. The man still did not know, I could only think again, reluctantly told him that the gallbladder is the usual bile. The person is not without guts. I then started to get a headache. I had a dry mouth again, and the main reason for my dry mouth every day was that I had to communicate to the patients what bile was, what a gallbladder was, and where the bile came from, so that they would understand that having a gallbladder removed was not a bad situation. First of all, let’s understand the source and destination of bile. Bile is secreted by the liver, and the capillary bile ducts of the liver contain bile duct cells, which are responsible for secreting bile, and then it is gathered in layers through the bile ducts to the left and right hepatic ducts, then from the left and right hepatic ducts out of the liver to the common hepatic duct, then to the common bile duct, and finally to the intestines to help digestion. Then the gallbladder, where it is, the original common hepatic duct and the common bile duct is a channel, the reason why the two are called, because between the two protrudes a sac-like thing, that is the gallbladder. Usually when not eating, the valve between the common bile duct and the intestine is closed, when the bile flows to the gallbladder inside and collected. When you eat, the gallbladder is stimulated to contract up and squeeze the bile into the intestine to help digestion. So from the perspective of bile flow, we can see that the gallbladder plays a role like a warehouse. The liver is the factory, responsible for producing a product that is stored in the gallbladder and then focused on flowing to the target when needed. And the bile ducts are like our logistics trunk line. In this case, the factory is important and the logistics trunk line is important, then the warehouse is much less important. In a sense, the warehouse is optional, and the gallbladder is in a similar position. So gallbladder removal has very little impact on the body. The goal of modern logistics is to reduce warehousing, and the body will regulate itself as needed without the gallbladder as a warehouse. First of all, the common bile duct will thicken, which means that the passage of bile from the liver to the intestine will become larger, in the same way that without the warehouse, the road will be widened. On the other hand, the body’s fluid regulation and the corresponding neurological regulation will undergo some changes. So are these changes harmful and what are their effects. Usually the obvious physiological changes that occur after gallbladder removal occur in the short term, usually within 1-3 months, and diarrhea may occur, especially after eating too much fatty food. A very small percentage of people also experience abdominal pain, which is a sign of passive dilation of the bile ducts. These symptoms occur in a small percentage and for a short period of time, but still some people will continue for a long time, about several months to more than a year. In the long term, some people have seen reports online of increased colon cancer rates after cholecystectomy, but with the most current evidence from evidence-based medicine, there is no increased incidence of colon cancer in people who have had their gallbladders removed. To summarize, gallbladder removal is not the absence of gallbladder, and gallbladder removal does not actually have much impact on the body.
