Cholecystectomy usually results from the development of gallbladder diseases, such as gallstones combined with acute cholecystitis and gallbladder tumors. Some patients may have some uncomfortable symptoms after gallbladder removal, such as diarrhea. In addition, since the gallbladder has the function of storing bile and secreting mucus, it may also lead to adverse effects such as indigestion and bile duct stricture after gallbladder removal. The sequelae of gallbladder removal are mainly bile reflux gastritis or esophagitis, post-cholecystectomy syndrome, etc. I. Effects: 1. Diarrhea: After cholecystectomy, it leads to the flow of bile into the intestinal canal, which can cause certain stimulation to the intestinal tract, resulting in excessive intestinal peristalsis and easily causing diarrhea. In addition, the lack of bile can lead to fat not being fully digested, thus causing steatorrhea; 2. This may lead to bile duct stenosis, which may manifest as nausea, abdominal pain, yellowing of skin and other symptoms. Second, the sequelae: 1, bile reflux gastritis or esophagitis: because the liver constantly produces bile, when too much bile in the bile duct may flow back into the stomach or even the esophagus, forming bile reflux gastritis or esophagitis, alkaline bile can affect the acidic environment in the stomach, appearing epigastric distension, belching and other symptoms, the esophagus may appear burning sensation; 2, post-cholecystectomy syndrome: that is, gallbladder removal sequelae, in extrahepatic bile ducts are damaged during cholecystectomy, resulting in postoperative bile duct stricture; or postoperative peribiliary infection causing bile duct damage or occlusive cholangitis, which can easily lead to post-cholecystectomy syndrome. Patients may experience pain and discomfort in the upper abdomen or right quadrant of the rib cage, often vague or dull pain with pressure, and severe patients may experience chills, high fever, jaundice, etc., weeks or months after cholecystectomy. 3. overgrowth syndrome, intestinal adhesions, etc. In addition, the incidence of colon cancer is increased after gallbladder removal compared to the general population. After gallbladder removal, patients should follow the doctor’s instructions to change the medication on time to promote good wound recovery. In the recent postoperative period, patients should pay attention to eating less and more meals, mainly light diet, and try to eat foods with low fat, low cholesterol and high protein, such as thin porridge, clear noodles, steamed egg custard, chicken breast and soy products, to avoid aggravation of indigestion due to the lack of gallbladder function.
