Pancreatic Cystic Lesion

The primary objective is to construct a multimodal AI model (Cyst-AI) based on EUS images and clinical data such as imaging features(CT or MRI) and laboratory tests to assist endoscopists in the diagnosis of pancreatic cystic lesions(PCLs), mainly differentiating mucinous from non-mucinous lesions. The secondary objective is to evaluate the model's effectiveness in risk stratification and clinical management for patients with PCLs.

Large prospective comparative observational study in numerous reference centers in France, comparing infectious complications in patients admitted for pancreatic cystic lesions (PCL) aspiration performed with or without antibiotic prophylaxis (ATBp) according to the usual practices. This is a prospective, comparative, observational, multicenter study, with the primary objective of comparing the infection rates in pancreatic cystic lesions (PCL) aspirated under EUS, with and without the administration of ATBp. A sample size of 1702 patients will be needed over a 3-year study period.
