Surgical techniques have improved and the number of people undergoing surgical treatment has increased accordingly. Although numerous clinical studies have confirmed that cholecystectomy is evidence-based, it does not mean that there are no complications. These complications include early incisional pain, vomiting, bleeding, and biliary fistulas, as well as later digestive dysfunction: abdominal pain, diarrhea, and steatorrhea. Digestive dysfunction is almost half as likely to occur, lasts almost three months or perhaps longer, and becomes a major postoperative concern. How to reduce and shorten the digestive dysfunction has also become a hot topic of clinical research. What changes occur in the organism after gallbladder removal? Bile is not secreted by the gallbladder, and the role of the gallbladder is mainly to further concentrate and temporarily store the bile secreted by the liver cells and regulate the amount of bile released into the digestive tract. After eating, especially after a high-fat diet, the gallbladder contracts, allowing the concentrated bile to enter the duodenum to aid in fat digestion. Thus, the sudden interruption of the gallbladder function after cholecystectomy and the lack of sufficient concentration of bile after eating cause impaired digestion and absorption of fat, and the bile cannot be concentrated and stored after cholecystectomy, and a large amount of bile salts continuously enter the colon and promote intestinal peristalsis, which aggravates diarrhea. Most of the diarrhea symptoms can be gradually relieved after 3 months. With the compensatory expansion of the biliary tract, it can play the role of part of the gallbladder to temporarily store bile, so that the bile secreted at the base does not enter the digestive tract directly and alleviate the stabbing into the intestine, thus increasing the residence time of the contents and reducing the number of bowel movements. At the same time, the bile released in large quantities after eating promotes digestion and also increases digestive function to reduce steatorrhea. After cholecystectomy, the gallbladder loses its function of concentrating and storing bile, and the bile enters the duodenum. The vagal reflex arc between the gallbladder and the gastric pylorus is damaged, and symptoms of pyloric dysfunction can occur. Most patients complain of persistent burning pain in the upper and middle abdomen, which cannot be relieved after taking acid-suppressing drugs or may be increased. A few patients may also present with retrosternal pain, or indigestive sensation in the stomach, or even vomit bile-like vegetarian food. Bile reflux is less common than bloating and diarrhea symptoms and lasts for a relatively shorter period of time. Low-fat diet – control symptoms The cholecystectomy style has been relatively well established and complications such as abdominal distension, diarrhea and bile reflux caused by improper surgery should be avoided, but these symptoms are mostly caused by the lack of gallbladder function and the compensatory function of bile ducts has not yet been established, so the main thing is to give regulation during the postoperative recovery period. Since digestion is mainly affected, the primary intervention is in the diet to minimize complications. The role of bile is mainly to assist in fat digestion, and the lack of temporary storage and concentration of the gallbladder causes abnormal fat digestion and absorption, which requires reducing the intake of fat and cholesterol, and strictly limiting the consumption of fried foods, animal offal, fatty meat, egg yolk and other foods containing high cholesterol. The diet should mainly consist of foods rich in protein, dietary fiber and vitamins, such as lean meat, aquatic products, soy products, seafood, fruits and vegetables, etc., to meet the needs of metabolism. Meals are mainly small and frequent, avoid overeating, and develop regular eating habits. Since high-fat diet can promote the release of cholecystokinin from the small intestinal mucosa, which can easily lead to reflux of gastrointestinal contents, they are all consistent in controlling postoperative complications. Emphasis is placed on paying attention to diet in addition to: minimizing activities that increase intra-abdominal pressure, such as excessive bending, wearing tight-fitting clothes and pants, and tightening the belt; abstaining from smoking and alcohol to avoid relaxing the esophageal sphincter. Impact on long-term quality of life: Usually, the bile duct will appear compensatory dilation in about 3 months, and patients after cholecystectomy can see that the common bile duct is obviously dilated in the shape of gallbladder, which can regulate the discharge of bile and play the role of gallbladder storage of bile. As long as postoperative health knowledge is strengthened, diet is strengthened, diarrhea patients focus on low-fat, high-protein and high-calorie, increase the number of meals, eat less and more meals, and after 3 months, when the body’s compensatory mechanism is initially formed, the fat ratio can be increased, subject to the absence of diarrhea and bloating, and gradually resume the general diet, but maintain a low-fat diet, do not overeat, there is almost no significant impact on the quality of life of long-term postoperative patients. It can even be said that the resulting controlled diet is superior to that of people without restrictions in preventing cardiovascular diseases and maintaining a healthy physique.
