Abstract Introduction: Acute Pancreatitis (AP) is a self-digestion of the pancreatic gland. Its aetiologies are multiple, dominated by lithiasic biliary disease and alcoholism. In case of acute pancreatitis of undetermined origin by different biological and radiological assessments, Endoscopic Ultrasound (EUS) plays an important role. The aim is to study the contribution of EUS in the etiological diagnosis of AP. Material and Methods: From October 2015 to October 2019, were includd all patients with acute pancreatitis of which etiology is either suspected or remains undetermined after an initial radiobiological assessment. The epidemiological, clinical, biological and endoscopic ultrasound data were collected from EUS records. Results: 53 cases of patients were explored (20%). The average age of the patients was 51.5 years, with a female predominance 58.5%; 47 patients (87.5%) were explored by EUS after 1 episode of AP, 3 patients (6.25%) after 2 episodes and 3 patients after 4 episodes (6.25%). The time to perform EUS was <1 week in 2 patients (3.77%), 2 weeks to 8 weeks in 37 patients (70%) and more than 8 weeks in 14 patients (62.5). Gallstones were objectified in 59.28% of cases: Biliary microlithiasis without choledocholithiasis (68%), biliary microlithiasis with choledocholithiasis (42%), IPMN in 20% of cases, 2 cases ( 3.78%) of chronic early pancreatitis, 1 case of vaterian ampulloma (1.88%), an appearance of cholangitis in a patient (1.88%), 1 case of hydatid material in the CBD (1.88%) in a patient operated for a LHC who presents calcified peritoneal HC, 1 case of pancreas divisum (1.88%) and in 4 cases (7.54%) EUS was normal, including 1 young patient in whom a genetic origin was suspected. Discussion and Conclusion: These preliminary results confirm that endoscopic ultrasound remains essential in the case of acute pancreatitis of unknown etiology after a negative radiobiological assessment, however, larger series are desirable to confirm our results.
