With the improvement of people’s living standards, the incidence of gallbladder stone patients is increasing year by year. Gallbladder stones can bring a series of problems such as pain, secondary cholecystitis, bile duct stones, acute pancreatitis, and jaundice. In the past, for patients with gallbladder stones and cholecystitis, hepatobiliary surgeons would not hesitate to say that everything was done. Cholecystectomy has always been the basic treatment for gallbladder stones and is considered the “gold standard”. In recent years, many surgeons have taken note of the function of the gallbladder and have come to realize that it is not the end all be all. However, more and more studies are now finding that removal of the gallbladder does not solve all problems and can have adverse consequences for patients. Adverse effects of gallbladder removal include: 1. side injuries during gallbladder removal: due to anatomical variation of the bile duct itself and adhesions caused by inflammation of the gallbladder, the hepatobiliary duct and the stomach and intestines may be damaged during surgery, causing serious complications. 2. Biliary reflux gastritis and esophagitis: Removal of the gallbladder will weaken the reserve function of bile, triggering the intermittent excretion of bile closely related to feeding into uninterrupted discharge into the duodenum, so that the probability of reflux into the stomach rises, eventually triggering reflux gastritis and esophagitis. 3, digestive function is affected, resulting in bloating, diarrhea: after gallbladder removal, the liver still secretes bile uninterruptedly, because there is no place to store it, at this time, whether the body really needs it or not, it can only keep excreting into the intestine, when eating a lot of fat and a lot of protein, often need a lot of bile to promote digestion, but at this time there is no “enough bile” inside the body When eating a lot of fat and a lot of protein, it often needs a lot of bile to promote digestion, but at this time the body does not have “enough bile”, so it will cause bloating, diarrhea and indigestion. 4. Increased incidence of common bile duct stones: After removal of the gallbladder, the common bile duct will be slightly dilated to replace part of the gallbladder’s function, and at this time, due to the relative narrowing of the Oddi’s opening, bile will be rotated in the bile duct in a vortex, and stones will be formed. 5, post cholecystectomy syndrome: after removal of the gallbladder, the role of regulating the biliary pressure disappears, the internal pressure of the bile duct rises, and the common bile duct becomes compensatory dilated. At this time, dilute bile is not stored through the concentration of the gallbladder, but directly enters the duodenum through the duodenal papilla, which increases the papillary load and makes it work under high pressure, easily triggering papillitis and sphincter spasm, and then causing right upper abdominal pain. This symptom is still a difficult point in clinical treatment.6. The incidence of colon cancer increases after cholecystectomy. Therefore, it is especially important to judge the function of the gallbladder before cholecystectomy. If the function of the gallbladder is basically normal and the inflammation of the gallbladder is not serious, it is recommended to remove the stones and preserve the gallbladder in such cases, so as to preserve the function of the gallbladder. After the biliary surgery, the “gallbladder protection” work. After the surgery, some protective measures should be implemented for the function of the gallbladder, and corresponding measures should be taken to promote the recovery of the gallbladder function as soon as possible, which is the key to prevent the recurrence of stones after the surgery. To protect the gallbladder, it is necessary to do a good job of prevention to prevent the recurrence of stones. For example, a regular and reasonable diet, more fiber and calcium-rich foods, avoiding too much practical fatty foods, and oral medications to relax the liver and stimulate the gallbladder, such as Mucuna pruriens, Chai Hu, Yuan Hu, Scutellaria baicalensis, Citrus aurantium, etc.
