Gallbladder stones are not a disease that only modern people get; it has a long history. According to statistics, about 10% of adults suffer from gallbladder stones, and in middle-aged women, the incidence of gallstone disease is as high as 15%. I. Which patients’ gallbladders cannot be preserved. 1, gallbladder in the acute inflammatory phase (including suppuration, gangrene, perforation, inflammatory package, gallbladder neck or gallbladder duct stone impaction, etc.). 2, gallbladder stones combined with bile duct stones, or mud-like stones. 3.Gallbladder atrophy. 4, adenomyosis of gallbladder or thickening of gallbladder wall, which cannot exclude gallbladder cancer. 5.The gallbladder is separated into two chambers. If you are a patient with the above conditions, you should follow the doctor’s advice and perform emergency or elective cholecystectomy if there is no contraindication to surgery. Do not wait and see to avoid the consequences. Second, these patients are suitable for gallbladder preservation. Gallbladder stones without symptoms, the so-called “resting state” of stones. You can hope to remove the stones and preserve the gallbladder. The gallbladder must have good contractile function. The gallbladder must not be too large or too small. History of open surgery, perforation or other acute inflammatory disease in the upper abdomen, smooth gallbladder mucosa, gallbladder wall within 3-4 mm, single or multiple stones, regular shape, good intracapsular sound, gallbladder diameter between 5-8 cm, and no intracapsular separation. Some gallbladder polyps. Ultrasound after oral cholecystography or lipid meal suggests: gallbladder contraction up to 1/3 or more. No significant age restriction, but younger people are more suitable. The above patients can be considered for gallbladder preservation surgery if they have the desire to preserve their gallbladder. The purpose of gallbladder preservation surgery is to preserve the functional gallbladder and try to clean the stones in the gallbladder. However, because the causes of stones are not fundamentally controlled, stones can still recur. Therefore, it is controversial in medical science at present. In my opinion: if the stones are removed 5-10 years after the recurrence, it should still be feasible, especially for young patients is more beneficial than bad. 2, the requirements of ultrasound: when doing ultrasound examination must understand the size of the gallbladder, there are descriptions of gallbladder mucosa, gallbladder wall thickness, gallbladder stones, intra-bladder translucency, etc., whether the hepatobiliary ducts are dilated with stones, separated, and whether they are mud and sand type stones. 3. Preoperative examination can only make preliminary judgment that the gallbladder can be preserved, which is not equal to successful gallbladder preservation. Therefore, one must be prepared for open or laparoscopic removal of the gallbladder. You should leave a way out for yourself and your doctor. 4.After biliary surgery, the patient should have a follow-up ultrasound in March, June, one year, two years, three years and five years after the surgery to find out whether there is a recurrence of stones. Oral anti-inflammatory and biliary tablets or ursodeoxycholic acid can be taken to prevent the recurrence of stones. Fourth, about how the doctor achieves the preservation of gallbladder The laparoscope combined with fiberoptic choledochoscope is used, and only 2 to 3 small holes are left in the abdominal wall to complete the operation. It not only preserves the gallbladder, but also is less traumatic than laparoscopic bile cutting, which is a veritable minimally invasive surgery. It is really a high-tech masterpiece.
