Biliary stone preservation is a treatment for gallbladder stones, which has been gradually carried out in hospitals across the country in recent years, and has become an important treatment for gallbladder stones, just like laparoscopic cholecystectomy. Under the active advocacy of my benefactor, Prof. Zhang Baoshan of Peking University Hospital and others, a national gallbladder preservation treatment group has been established. However, it is not yet widely accepted because of its by certain recurrence rate. We select patients strictly according to the indications and adopt the technique of combining laparoscopy and choledochoscopy to truly achieve minimally invasive treatment. It also opens a new way to expand the scope of laparoscopic minimally invasive treatment. Compared with open or small incision biliary stone extraction, the laparoscopic + choledochoscopic approach is safer and more scientific, with less trauma. During the operation, the bottom of the gallbladder was raised from the perforation hole of the abdominal wall under laparoscopic surveillance, and the fiberoptic choledochoscope was placed after the opening. Tian Hu, Department of Hepatobiliary Surgery, Shandong Qianfo Mountain Hospital The indications for biliary stone extraction are relatively strict, mainly for adolescent patients with mild gallbladder inflammation, normal or basically normal gallbladder contraction function, or in the growth and development period, as well as for patients with a strong desire for biliary preservation. It adds a new means of treatment for some patients with gallbladder stones, and the procedure is generally very safe as it can be discharged three days after surgery. This method can also be used for the treatment of some patients with gallbladder polyps, called biliary preservation for polyps. At present, hepatobiliary surgery has formed a system of minimally invasive laparoscopic treatment. Except for complicated intrahepatic bile duct stones that require open surgery, all gallstones can be treated by minimally invasive methods, collectively known as “triple-laparoscopic” treatment of gallstones. All endoscopic treatment and laparoscopic surgery can be done by me independently, which is very safe and efficient. Looking back on these ten years, I am very grateful to the late Prof. Liangfang Xia of Guiyang Medical College for showing me the way to this path, which has benefited me greatly, to my mentors Prof. Baoshan Zhang and Prof. Qiushi Feng, and to the American teachers at NYU Medical Center. May my skills help to relieve the pain of more patients. Gallbladder stones: laparoscopic cholecystectomy (LC); laparoscopy + choledochoscopy for biliary stone extraction. Gallbladder stones + common bile duct stones: retrograde cholangiopancreatography, papillary sphincter dissection or dilation (ERCP, EST), nasobiliary drainage (ENBD) + laparoscopic cholecystectomy; laparoscopic cholecystectomy + common bile duct choledochoscopy for stone extraction and T-tube drainage. Intra- and extra-hepatic bile duct stones: laparoscopic cholecystectomy + common bile duct choledochoscopy for stone extraction, T-tube drainage, postoperative intrahepatic bile duct extraction via T-tube sinusoid.
