Background: Many studies, almost all in an Endoscopic Retrograde Cholangiopancreatography (ERCP) setting, have been conducted to establish if a link exists between periampullary diverticula (PADs) and biliopancreatic diseases but the issue is still debated.
Aims: The objective was to clarify the link between PADs and biliopancreatic disease, for the first time using Endoscopic Ultrasound (EUS).
Methods: We retrospectively reviewed our database seeking patients scheduled for EUS with an indication that entailed the exploration of the second duodenum. For each patient with a PAD enrolled in the study, 6 controls were randomly selected.
Results: 2475 patients met the inclusion criteria. Among them, 185 subjects with a PAD were found (prevalence 7.5%), 1110 subjects served as controls. Patients with a PAD had more frequently a history of cholangitis (8.1 vs 2.2%; OR 3.99, p < 0.001), a higher prevalence of common bile duct (CBD) dilation (44.3 vs 28.2%; OR 2, p < 0.0001) and a higher prevalence of CBD stones (34.1 vs 19.6%; OR 2.1, p < 0.0001). No differences were found about history of jaundice, acute/recurrent pancreatitis or EUS signs of chronic pancreatitis.
Conclusion: Whereas PADs were linked with history of cholangitis, CBD stones and dilation, no association was found with pancreatic diseases.
