Introduction: Endoscopic ultrasound (EUS) is a method of exploration in gastroenterology, it combines ultrasound and endoscopy for the examination of the digestive tract and nearby structures. It is an ultrasound technique that allows the use of high-definition ultrasound transducers. Materials and methods: It is a descriptive retrospective study covering a period of 34 months, from 01/2019 to 10/2021. It concerned 100 patients who had endoscopic ultrasound for biliopancreatic pathology, in the and the university hospital Sheikh Khalifa. We noted the demographic, clinical and morphological data, such as transcutaneous ultrasound, abdominal CT scan and MRI as well as the EUS. The results of the EUS were compared with the imaging and histology data when performed. We were therefore able to evaluate the reliability of each examination and thus its strong and weak points. Results: The average age of our patients was 58 years, with a sex ratio: 1.05. The symptomatology was dominated by abdominal pain and jaundice, the biology by cytolysis and biological cholestasis syndrome. We noted a predominance of tumor pathology with 42% followed by inflammatory pathology: acute pancreatitis as part of the etiological assessment. The reliability of EUS in the diagnosis of pancreatic cancer is 88% with a reliability of abdominal CT of 68%. Our study also allowed us to evaluate with precision the reliability of detection of lymph node and vascular invasion of biliopancreatic cancers, which was 88%. We also noted other pathologies for which EUS was a good diagnostic tool, main bile duct stones but also cystic lesions of the pancreas. Conclusion: In view of the comparative study of these results with the other types of explorations, of which the EUS, proved to be more effective in the exploration of the pancreatic region especially in for the assessment of tumor extension and diagnosis of choledocholithiasis and characterization of cystic lesions. The EUS has a therapeutic interest ....
