A female patient, 50 years old, was found to have gallbladder stones for four years and requested gallbladder stone extraction surgery. After detailed medical history and careful physical examination, the patient was found to have static stones (without any clinical symptoms, only found during physical examination), good general condition, no coexisting diseases such as diabetes mellitus, hypertension, heart disease, etc., and the patient subjectively requested biliary stone extraction surgery. It was initially determined that the patient basically met the requirements for biliary stone extraction surgery, but further examination was required to determine whether he fully met the requirements. A detailed ultrasound examination revealed multiple gallbladder stones with normal gallbladder wall thickness, a patent gallbladder duct without stones, good gallbladder contraction after a lipid meal, and normal liver and bile ducts. The imaging and functional examinations suggested that the patient met all the conditions for biliary stone extraction surgery. Under general anesthesia, a laparoscope was first placed through a 1 cm hole in the umbilicus to explore the entire abdominal cavity and gallbladder. The gallbladder was sutured to ensure that the stones were removed and the cystic duct was open. After the operation, the patient recovered well and the ultrasound showed that the gallbladder was normal. The patient was successfully discharged 5 days after the operation. In view of the important physiological function of the gallbladder and the existence of gallbladder removal complications, the view of “leaving the gallbladder under the knife” is being recognized by more and more medical professionals and gallstone patients; academician Huang Zhiqiang, the father of hepatobiliary surgery in China, even supports this. At present, many hospitals in China are already carrying out gallstone removal surgery. The indications for the surgery include: good gallbladder function, no obstruction of the cystic duct, stones can be removed, and the patient has subjective requirements for biliary preservation, etc. Minimally invasive biliary preservation surgery can also be performed for some gallbladder polyps. At present, this surgery is mostly done with the help of laparoscopy and cholangioscopy, and only 1-2 small holes are needed in the abdomen to complete the surgery, with little trauma and quick recovery.
