Three-Part Question:
In an [adult with acute severe necrotising pancreatitis] does [Step up surgical intervention better than early surgical necrosetomies/] in [ improving survival and better outcome]
Clinical Scenario:
A 45 year old male came to A&E with sever upper abdominal pain, and upon examination there is signs pf peritonism and elevated serum amylase more than 4 folds in addition to elevated CRP, WBC and fever.Within two days, he developed signs of acute severe necrotisig pancreatitis with Cullin and Turner signs and AKI for that we kept him on conservative treatment for more than 10 days

Author Commentary:
All studies included in this BET are systematic reviews and meta-analysis with at least moderate evidence of there results.
Step up Minimal invasive therapy is superior to open surgical drainage in different aspects according to differet studies.However, MID is usually reduce the rate of multi-organ failure and morbidities associated with acute severe pancreatitis, it has no statistically significance on survival i most of the studies involved in this BET
Step up Minimal invasive therapy is superior to open surgical drainage in different aspects according to differet studies.However, MID is usually reduce the rate of multi-organ failure and morbidities associated with acute severe pancreatitis, it has no statistically significance on survival i most of the studies involved in this BET
Bottom Line:
Minimal invasive therapy should be used in step up manner in treating acute severe necrotising pacreatitis aiming to reduce morbidity and improving outcome.
