Glutamyl transpeptidase is generally referred to as γ-glutamyl transpeptidase, and high γ-glutamyl transpeptidase can usually be referred to gastroenterology, hepatobiliary surgery and other departments. 1. Gastroenterology: Usually, hepatocellular injury caused by acute viral hepatitis or hepatocellular necrosis caused by chronic hepatitis can lead to high γ-glutamyl transpeptidase, in addition, cirrhosis and pancreatitis may also cause elevated γ-glutamyl transpeptidase, so patients can go to the gastroenterology department of the hospital for consultation. 2. Hepatobiliary surgery: obvious increase of γ-glutamyl transpeptidase can be seen in primary or secondary hepatocellular carcinoma, biliary cirrhosis, pancreatic head carcinoma, extrahepatic biliary tract carcinoma and other diseases, so patients can go to hepatobiliary surgery department of hospital for consultation. High glutamyl transpeptidase requires prompt medical treatment, and patients are advised to go to relevant departments for symptomatic treatment according to their own conditions.
