The patient, a 31-year-old female, was diagnosed with gallbladder stones and chronic cholecystitis at a local hospital for six months due to right upper abdominal distension and pain. In March 2005, she underwent open cholecystectomy in the local hospital. The common hepatic duct was damaged during the operation. At that time, the injured common hepatic duct was repaired and the common bile duct T-tube was drained. Fever, chills and jaundice appeared 1 week after the operation, diagnosed as bile leak, and emergency abdominal drainage was performed at the local hospital (second operation). After the operation, the symptoms subsided, but the jaundice progressively worsened. 1 month later, a dissection was performed at the local hospital (third operation), during which the common hepatic duct was found to be narrowed and scarred with atresia, making it extremely difficult to separate the common hepatic duct. The case was so complicated that the main doctor could not handle it at that time, so he urgently asked the most famous local hepatobiliary surgeon to operate on the stage, who also could not handle it, and only ended the operation after putting a drainage tube to drain the bile by widening the mouth of the common hepatic duct. The surgery did not solve the fundamental problem, and the local doctor told the family that they could only go to Beijing for treatment. After arriving in Beijing, the patient and his family visited several major hospitals and finally chose to have surgery at the Hepatobiliary Surgery Department of Beijing General Hospital of Military Medicine. After thorough preoperative preparation, many preoperative discussions and a well-designed surgical plan, the patient was operated in our department in May 2005. During the operation, extensive abdominal adhesions were seen, a large amount of scar tissue was formed in the hepatic hilum, the hepatic hilum was retracted, and no common hepatic duct could be found outside the liver. The lower part of the square lobe of the liver was resected and the common hepatic duct was found, which was hardened, with fibrous scar tissue and narrow lumen. The common hepatic duct was incised and extended along the left hepatic duct for about 3 cm. The opening of the right posterior lobe hepatic duct was dilated. Anastomosis of the common hepatic duct and left hepatic duct opening with jejunum was performed. The patient recovered well after surgery, and the patient returned to work 2 months after surgery. Six months after the operation, the patient came to our hospital for review and the liver function was fully restored to normal, so the left and right hepatic duct support drains were removed. The patient has now been followed up for nearly 6 years, and his life and work are completely normal. The patient had a high bile duct injury caused by cholecystectomy, which was not treated properly by the local hospital for several times, resulting in severe bile leakage, biliary peritonitis, and abdominal infection, resulting in bile duct stenosis and scar formation at the injury and initial repair, and extensive adhesions, fibrosis, and scarring in the hepatic portal. The surgery was extremely complex and difficult. Six years after the operation, the patient is doing very well in all aspects and has completely returned to normal life and work, indicating that the final surgery was successful. With the popularity of biliary surgery and the widespread use of laparoscopic cholecystectomy, there is a trend toward an increase in medically induced biliary injuries. The vast majority of medically induced biliary injuries occur during cholecystectomy. Authoritative statistics show that the incidence of biliary tract injury from open cholecystectomy is 0.2% to 0.25%, while the incidence of biliary tract injury from laparoscopic cholecystectomy is 0.5% to 1.0%. The recent manifestations of medical bile duct injury are bile leakage, biliary peritonitis, jaundice, fever, abdominal pain, white clay-like stools, and in some patients, massive abdominal exudate, pleural cavity exudate, subdiaphragmatic abscess, interstitial abscess and pelvic abscess. If not treated promptly, it often leads to serious consequences or even death. The long-term manifestations of bile duct injury are mainly bile duct stenosis, i.e. obstructive jaundice, recurrent biliary infections (including high fever, chills, abdominal pain, etc.), and some patients will eventually lead to liver abscess, sepsis or biliary cirrhosis, portal hypertension, etc., which seriously threaten patients’ lives. Surgical treatment of bile duct injuries caused by biliary surgery and subsequent biliary strictures is often difficult and requires a specialist with extensive experience. Surgery should be performed with great care, choosing the appropriate method, and the instruments and sutures used during surgery. In addition, the timing of surgery should be properly controlled, as a poor grasp of the opportunity often leads to surgical failure, which will cause lifelong pain to the patient.
