摘　　要：BACKGROUND Annular pancreas(AP)is a rare congenital abnormal rotation of the pancreas.AP rarely occurs in adults.Pancreatic tumors and ampullary tumors are related to AP,so the discovery and treatment of AP are essential.CASE SUMMARY This study investigated the clinical manifestations,imaging features,complications,and treatment of six patients diagnosed with AP at the Department of Hepatobiliary and Pancreatic Surgery,First Hospital of Jilin University from January 2010 to June 2020.There were four males and two females,with an average age of 56.00±9.86 years old.In this study,abdominal pain and jaundice were the main clinical manifestations.Imaging can show the“crocodile jaw sign”or“double bubble sign”.CONCLUSION For patients with duodenal or biliary obstruction,physicians should give priority to AP when imaging examinations suggest that the duodenum is wrapped with tissue similar to the density of the pancreas.Symptomatic patients should actively undergo surgical treatment.
