The diagnosis of surgical obstructive jaundice is clinically based on the following two aspects: 1. imaging examinations; 2. examination of liver function indicators. Obstructive jaundice can be found on imaging films from the enlarged gallbladder, and the common bile duct had thickened and dilated, while stones can be found in the common bile duct, and sometimes the intrahepatic bile duct is dilated. For more detailed information, a CT examination of the liver and gallbladder can be performed under the guidance of a physician to reveal more detailed changes in the liver and gallbladder. Obstructive jaundice can be found in liver function tests with elevated total bilirubin and more pronounced elevation of direct bilirubin, although transaminases are not significant, and the cause of obstructive jaundice is caused by hepatobiliary ductitis, hepatobiliary stones, hepatobiliary tumors, hepatobiliary trauma, pancreatic and duodenal tumors, etc. The symptoms are manifested as yellow staining of the skin and sclera and pain in the upper abdomen, i.e., impairment of liver function. Therefore, if the biliary obstruction is not removed in time, it will cause further liver function problems and eventually death from liver failure.
