Wang was diagnosed with acute obstructive cholangitis (choledocholithiasis) and admitted to the hospital because of epigastric pain with scleral yellowing for four days and fever for one day, requiring emergency surgery. As Wang had a history of radical surgery for gastric cancer, it was difficult to remove the common bile duct stones through the opening of the duodenal papilla by gastroscopy, and the only way to solve the problem completely was to do open surgery, but Wang did not agree with the fear of surgery, so he has been delayed until now and is facing immediate surgery. After reading all the examinations and understanding Wang’s specific situation, to his surprise, the chief surgeon said he could try laparoscopic surgery to solve the problem at one time, because many friends around him had gotten a good recovery after laparoscopic surgery because of gallbladder stones, so Wang agreed on the spot. The common bile duct incision was closed in one stage. He was able to get up 6 hours after the operation, and the abdominal drainage tube was removed on the 5th postoperative day and he was discharged the same afternoon. Laparoscopic cholecystectomy as the “gold standard” of cholecystectomy surgery has been recognized and widely accepted by the medical community and patients. However, when patients are seen with a combination of common bile duct stones, they may be advised to undergo traditional open surgery because laparoscopic common bile duct exploration is far from being as popular as laparoscopic cholecystectomy. Most conventional open surgical methods of treating common bile duct stones suffer from high trauma and slow postoperative recovery. At present, the treatment of gallbladder stones combined with common bile duct stones is mostly performed in two ways internationally, one is to use ERCP (Endoscopic Retrograde Cholangiopancreatography) combined with laparoscopic cholecystectomy; the other is the aforementioned The other one is the laparoscopic cholecystectomy and common bile duct exploration and stone extraction with one-stage suturing method. The former ERCP technique has a high success rate and is minimally invasive, as it performs minimally invasive surgery through the gastrointestinal tract and allows for stone extraction through an incision of less than 1 cm in the duodenal papilla. However, during duodenal papillotomy (EST), the sphincter of Oddis at the lower end of the common bile duct, which is the valve of the common bile duct, may be damaged, and once damaged, it may easily lead to backflow of food residue into the common bile duct, which is a factor leading to recurrence of bile duct stones and has certain disadvantages. Therefore, with the improvement of laparoscopic surgery technology, the laparoscopic cholecystectomy choledocholedochal exploration and extraction of stones in one stage suture is gradually accepted and promoted. This surgical method saves the steps of ERCP and saves the treatment cost accordingly than the former, so that patients can reduce the pain of doing gastroscopy. According to the specific conditions of different patients, some experts who are good at laparoscopic surgery further evolve some new surgical methods on this basis, such as some patients with thicker gallbladder ducts can perform laparoscopic cholecystectomy via cholecystic duct choledochoscopic choledochotomy for stone extraction without incision of the common bile duct, further reducing trauma and, like ordinary patients with simple laparoscopic cholecystectomy, recover quickly and be discharged early. Compared with traditional open surgery, laparoscopic choledochotomy not only results in less trauma and faster recovery for the patient, but also avoids the loss of digestive fluid, and due to the significantly reduced stimulation of the lower bile duct and sphincter of Oddis and the precise “microscopic” suture of the common bile duct, suitable patients can Early recovery, reduced hospitalization time and reduced costs.
