Safety of EUS-guided gallbladder drainage using a lumen-apposing metal stent in patients requiring anticoagulation

Background and Aims: EUS-guided gallbladder drainage (EUS-GBD) can be used to treat acute cholecystitis in patients with medical comorbidities that prevent definitive operative management. Historically, nonsurgical management of cholecystitis was achieved by way of percutaneous gallbladder drainage. Methods: We examined the periprocedural bleeding rate of EUS-GBD for acute cholecystitis using lumen-apposing metal stents in 5 high-surgical-risk patients requiring anticoagulation. Data on 5 nonoperative candidates with acute cholecystitis who underwent EUS-GBD were studied retrospectively. Results: There were no immediate or delayed postprocedure adverse events, including bleeding. Conclusions: Although further study is needed, EUS-GBD appears safe in patients who require periprocedural anticoagulation

Autoimmune pancreatitis in patients with inflammatory bowel disease - a real-world multicentre collaborative ECCO CONFER study

Autoimmune pancreatitis (AIP) is rarely associated with inflammatory bowel disease (IBD). Long-term outcomes of AIP and IBD in patients with AIP-IBD coexistence and predictors of complicated AIP course are scarcely known. An ECCO COllaborative Network For Exceptionally Rare case reports project (ECCO-CONFER) collected cases of AIP diagnosed in patients with IBD. Complicated AIP was defined as a composite of endocrine and/or exocrine pancreatic insufficiency, and/or pancreatic cancer. We explored factors associated with complicated AIP in IBD. We included 96 patients (53% males, 79% ulcerative colitis, 72% type 2 AIP, age at AIP diagnosis 35±16 years). The majority of Crohn's disease (CD) cases (78%) had colonic/ileocolonic involvement. In 59%, IBD preceded AIP diagnosis, whereas 18% were diagnosed simultaneously. Advanced therapy to control IBD was used in 61% and 17% underwent IBD-related surgery. 82% of patients were treated with steroids for AIP, the majority of which (91%) responded to a single course of treatment. During a mean follow-up of 7 years, AIP complications occurred in 25/96 (26%) individuals. In a multivariate model, younger age at AIP diagnosis (OR=1.05, P=0.008), family history of IBD (OR=0.1, P=0.03) and CD diagnosis (OR=0.2, P=0.04) were associated with uncomplicated AIP course. No IBD or AIP-related deaths occurred. In this large international cohort of patients with concomitant AIP-IBD, most patients have type 2 AIP and colonic IBD. AIP course is relatively benign and long-term outcomes are favourable, however, one-quarter develop pancreatic complications. Age, familial history of IBD and CD may predict uncomplicated AIP course
