Pancreatic and peripancreatic collections (PPC) are a known complication of acute pancreatitis. They are categorized into four types of collection: (1) acute peripancreatic fluid collection, (2) pseudocyst, (3) acute necrotic collection and (4) walled-off necrosis. Most PPC resolve spontaneously or are persistent but asymptomatic. Intervention is needed in a minority of patients with infected or symptomatic collection. Endoscopic ultrasound-guided transmural drainage is currently the first-line treatment option for PPC management. It has shown great technical and clinical success, similar to percutaneous or surgical approaches, but with lower morbidity and costs and better quality of life. In this review article, the GRUPUGE presents an updated perspective on the potential role of endoscopic ultrasound-guided drainage of peripancreatic collections, addressing the selection criteria and the technical issues of different techniques and analysing emerging data on their efficacy and safety.

As coleções pancreáticas e peripancreáticas constituem uma complicação conhecida de pancreatite aguda. As coleções são classificadas em quatro tipos: (1) coleção líquida peripancreática aguda, (2) pseudoquisto, (3) coleção necrótica aguda e (4) coleção necrótica encapsulada (walled-off necrosis). A maioria das coleções peripancreáticas resolvem espontaneamente ou mantém-se assintomáticas. A drenagem está indicada numa minoria de doentes em que a coleção infecta ou se torna sintomática. A drenagem de coleções peripancreáticas guiada por ecoendoscopia é atualmente considerada a primeira linha de tratamento. Os procedimentos guiados por ecoendoscopia têm mostrado uma elevada taxa de sucesso técnico e clínico, semelhante às abordagens cirúrgica e percutânea, mas está associada a menor morbilidade e custos e a melhor qualidade de vida. Neste artigo de revisão, o GRUPUGE apresenta uma perspetiva atualizada do papel da ecoendoscopia na drenagem de coleções peripancreáticas, abordando critérios de seleção e questões técnicas relativas aos diferentes procedimentos, e analisando os dados disponíveis sobre a sua eficácia e segurança.
