Many patients with gallbladder stones have misconceptions about gallbladder removal for fear of affecting digestive function, and this concern is unnecessary. First of all, when you have gallbladder stones, you should see a general surgeon or hepatobiliary surgeon so that you can get proper guidance and effective treatment. Generally physicians will recommend either surgery or conservative treatment or regular review after seeing them. These recommendations are backed by data and even blood lessons. In clinical practice, there are many cases that started as gallbladder stones and then evolved into cholecystitis, gangrene, perforation, cholangitis, pancreatitis, cirrhosis, gallbladder cancer, and even death, so it is important to pay attention to gallbladder stones and follow the advice of physicians. Generally one of the following conditions should be considered for surgical removal of gallbladder: 1, the number of stones and stone diameter ≥ 2-3cm; 2, calcification of gallbladder wall or porcelain gallbladder; 3, gallbladder wall thickening (> 3mm) that is accompanied by chronic cholecystitis; 4, accompanied by gallbladder polyps > 1cm; 5, children with gallbladder stones, such as asymptomatic, in principle, no surgery, first observation, regular review of gallbladder ultrasound. Once you choose to accept the recommendation of surgery, it is natural to ask whether the absence of the gallbladder will affect the digestive function. Then we need to know what the function of the gallbladder is. The main function of the gallbladder is to store bile. After eating, the gallbladder contracts, allowing the stored bile to be discharged into the duodenum to aid in the digestion and absorption of food. Then, once the gallbladder is removed due to a lesion, the concern that the gallbladder will affect the digestive function after the removal of the gallbladder is somewhat justified but not correct. Because the gallbladder is not an indispensable organ in the body, there are many higher mammals, such as horses, elephants, deer, whales, etc., they are born without a gallbladder, and their lives are no different from those of some animals with gallbladders. Besides, there are a few people who are born without a gallbladder due to congenital abnormal embryonic development of the gallbladder, but they live healthy lives as normal people. Cholecystectomy has been performed worldwide for more than 100 years and most patients who have undergone cholecystectomy live like normal people. The patient’s symptoms disappear immediately after the removal of the diseased gallbladder, and although the gallbladder is lost and its function of storing bile is lost, there is no major impact on the patient’s digestive and absorption functions. Scientific studies have shown that the digestive and absorption functions of patients after gallbladder removal are not much different from those of normal people. Most of the gallbladder stones are cholesterol stones, and the content of bile acids in the bile of patients with cholesterol stones will gradually increase after gallbladder removal, so that the bile that was oversaturated before the operation can gradually become normal bile, and the over-saturated bile will easily form stones. Therefore, if the bile duct stones can be completely removed when the gallbladder is removed, generally cholesterol stones will not recur, so there is no need to worry as it will not bring adverse effects on health and digestion and absorption after gallbladder removal. In addition, after the gallbladder is removed, the bile ducts will be compensated to expand, the wall of the bile ducts will be compensated to thicken, the mucus glands of the bile ducts will increase, and the bile will often be discharged into the duodenum to compensate for the bile storage function of the gallbladder, and at the same time, it will not affect the digestion and absorption of fats. Of course, the recovery of the body after surgery and the establishment of compensatory functions need a process, in this process, the intake of animal fats and eggs should not be too much, and the fat content in food should be increased slowly, so that the body has a gradual adaptation process.
