Many surgeons do not know enough about the digestive function of the gallbladder, thinking that the gallbladder is just a bag that retains some bile and water; at most, it has some contraction and excretion functions, but other functions such as immunity, balancing the pressure in the bile duct, concentration and digestion are unknown. Even after cholecystectomy patients have some complaints of indigestion, the surgeon thinks that the temporary discomfort after surgery will be adapted after 1-3 months, and the patient will be transferred to gastroenterology and pushed away. In fact, it is a big mistake. Although the small gallbladder is not as large as the liver, plus the appearance is very simple, it seems to be just a bag; but in fact, “the liver and gallbladder together”, the gallbladder and liver complement each other and have a very important role in regulating the digestive function of the human body. First of all, the bile should be concentrated. Bile is just secreted from the liver called liver bile, most of which is water (97.8%), and the content of various digestive enzymes is very thin, so the regulation of digestive function is very weak; however, when liver bile enters the gallbladder, the gallbladder has a clever concentration function, the water of liver bile is slowly sucked back into the blood, concentrating bile; the gallbladder can concentrate liver bile 30 times, so high concentration of high-quality bile deposited in the bile The gallbladder can concentrate liver bile 30 times, and such high concentration and high quality bile is stored in the bile reservoir (gallbladder) waiting for the body’s digestive function needs. Secondly, the liver and gallbladder cooperate with each other to skillfully regulate the needs of digestive function. With high quality and high concentration of gallbladder bile in mutual coordination between gallbladder and liver, the gallbladder has a unique regulating role: when the human body does not eat, the gallbladder rarely excretes bile; when the human body eats a vegetarian diet, it excretes less; when eating a high-fat, high-protein diet, it excretes more, adapting to the needs of the human body, very clever. However, when your gallbladder has been removed, if you eat sorghum thick, such as: chicken, duck, fish, Western cream; at this time need a lot of high quality and high concentration of bile to participate in digestion, unfortunately, the valuable gallbladder no longer exists, at this time high concentration of bile no, only a small amount of just secreted thin liver bile, far from meeting the body’s digestive needs. But the human intestine has received these high fats, and the intestine is incapable of digestion, so it has to tolerate the abdominal distension, abdominal pain and suffering brought by indigestion, followed by the manifestation of diarrhea and even fatty leaking. It is not surprising that many patients after cholecystectomy mostly complain of the pain of not being able to eat meat and oil, and even for more than ten years they cannot adapt to it; that is, it has become one of the very difficult to treat persistent diseases in gastroenterology. However, these problems are ignored by many surgeons, forming the current surgical community does not recognize the sequelae brought about by cholecystectomy, resulting in the sad situation of the surgical community casually cutting off the gallbladder.
