What to do with postoperative jaundice of gallstones Huang Gang, Department of Hepatobiliary and Pancreatic Surgery, The First Affiliated Hospital of Guangzhou Medical University Huang Gang, Department of Hepatobiliary Surgery, The First Affiliated Hospital of Guangzhou Medical College. He underwent “choledochotomy for stone extraction, cholecystectomy and ‘T’ tube drainage” in a university hospital in Xinjiang six months ago due to “gallstones”. After the operation, the patient still had abdominal distension, jaundice was reduced, but moderate jaundice did not subside, and with the “T” tube home, abdominal pain and distension often appeared. In order to completely solve his suffering, he came to Guangzhou for medical treatment. After a routine preoperative examination, a cholangiogram was done for the patient’s condition, and a comprehensive understanding of the patient’s whole body, biliary tract and liver was obtained. After the diagnosis was clear, surgery was performed, and the common bile duct and common hepatic duct were incised, the stenosis was trimmed, and a bile duct jejunostomy was performed. Post-biliary jaundice is a common complication of biliary surgery, mostly due to biliary injury, but in a few cases due to failure of surgery to release the cause of obstruction. This case was due to postoperative common hepatic duct stenosis resulting in biliary obstruction and obstruction of bile drainage causing jaundice and abdominal distension, etc. Medication was not effective and surgery was necessary to release the stenosis in order to achieve treatment. Most of these cases are caused by the inadequate technique of the surgeon, and a small part is due to the variation of the patient’s anatomy, which the surgeon failed to detect and is also due to the unachieved technique. Therefore, the fundamental measures to prevent such complications are to improve the surgeon’s biliary technique, “standardize the operation, see the biliary structure, fine anatomy, and precise movements” during the operation, and to avoid injuries.
