The patient, Qian Moumou, female, 72 years old, had a history of “episodic chest tightness for more than 10 years” and had been seen in the cardiology departments of various hospitals in our city. She had coronary angiography: left anterior descending branch stenosis, combined with myocardial bridge, considered as coronary artery disease, unstable angina; hypertension grade 3, very high risk. The patient’s symptoms could be relieved after treatment with mild blood activation and improvement of myocardial blood supply. Recently, the patient had another attack and was admitted to our cardiology department. After admission, the attending physician took further detailed medical history. After the operation, he had a light diet and drank porridge, etc. On examination, he had significant pressure pain in the right upper abdomen and wasted body type. He then considered whether there was a combination of biliary disorders, and an MRI of the upper abdomen showed multiple stones in the left intrahepatic secondary bile duct, common hepatic duct, and extrahepatic bile duct with cholangitis. After combining the patient’s past medical history and discussing the condition with our department, we concluded that the patient’s episodic chest tightness was highly related to long-term biliary stones, recurrent biliary tract infections and biliary heart syndrome. After communication with the patient, the decision was made to perform surgical treatment. During surgery, it was found that there was injury to the middle part of the common bile duct during the previous external cholecystectomy, and the circumferential narrowing of the middle part of the common bile duct to a pinhole-sized hole was the main cause of secondary intrahepatic and extrahepatic biliary stones. During the operation, the left intrahepatic bile duct was removed by bile duct excision + bile ductplasty in the hilar region + common hepatic duct-jejunum Roux-en-Y anastomosis. After the operation, the patient was discharged from the hospital. To date, no preexisting symptoms have appeared.
