Composite Index for Outcome Burden in Acute Cholangitis

The goal of this retrospective observational study is to construct a composite outcome to measure the success of treatment in patients who are presenting with acute cholangitis (blockage and infection of bile ducts) and undergoing a drainage procedure with different modalities. The study is not intended to test any predetermined hypothesis and does not have any comparison group. The participants' data are collated from retrospective hospital records and analysed for the purpose of the study. All the procedures are in place to ensure the confidentiality of the study participants while collating, analysing and sharing study findings.
