Acute Pancreatitis With Infected Necrosis

This registry aims to analyze long-term outcomes of therapeutic EUS (T-EUS) procedures, as well as to describe clinical and technical variables potentially predicting clinical success or adverse events, for a better selection of ideal candidates. The study also includes standard alternatives to T-EUS procedures for outcomes comparison.

The goal of this observational study is to evaluate the orointestinal microbiome and microbial derived metabolome in patients suffering from acute pancreatitis as a biomarker for severity. The main questions it aims to answer are: * Can the orointestinal microbiome robustly predict the course of acute pancreatitis? * How does the microbiome impact the severity of an acute pancreatitis? Buccal/ rectal swabs, plasma and stool is collected from patients with acute pancreatitis within 48h after hospital admission.
