Outcome measures number of organ failure, hospital stay, requirement of ventilator support, need for intervention and mortality were compared between different groups. Results: 189 acute pancreatitis patients (mean age 38.85(13-90) years, 70% males) were studied. Overall, 151(79.9%) patients had fluid collections and 38 (20.1%) had no collections. Location of collections was pancreas only in 5(3.31%), peripancreatic only in Saracatinib supplier 52(34.43%), distant only in 5(3.31%), peripancreatic and distant in 52(34.43%), and pancreatic with peripancreatic/distant in 38(25.1%). Incidence and severity of organ

failure (3 organ failures with Marshall score &gt 2 vs 2 organ failures) were more in patients with peripancreatic+distal collections when compared to the rest of the groups Also correspondingly this group with peripancreatic+distal collections had more morbidity with increased ventilator and dialysis requirements, prolonged hospital stay (22 days vs. 17 days), increased infections (61% vs. 31.2% ), increased need for intervention and increased mortality(46.8% vs. 34.3%). Conclusion: Occurrence of

acute fluid collections in peripancreatic area in conjunction with distant collections increases the need for intervention and morbidity and mortality suggesting need for a different protocol for management of collections as per the location.

and urinary Neutrophil gelatinase-associated lipocalin (NGAL) for AKI and severity in patients with acute pancreatitis Methods: 50 consecutive patients with acute pancreatitis within 3 days of symptom onset and age matched healthy controls were included in the study. Patients were tested for urinary and serum NGAL levels (ELISA) within 24 hours of admission and after 72 hours. Serum and Urine NGAL was tested once in controls. Results: Pancreatitis patients were aged 13-85 yrs(Range), males-60%, with 31 age and sex matched controls. The mean serum-NGAL levels (587.66±251.5ng/ml[day1], 573.98±259.86ng/ml[day3]) and mean urine-NGAL levels (252.84±165.89ng/ml[day1], 202.36±132.46ng/ml[day3]) were significantly higher in AKI (p<0.05). Both serum NGAL (cutoff day1-705ng/ml & day3-650 ng/ml, AUC-0.77) and urine NGAL (cut off day1-293ng/ml&day3-205ng/ml, AUC-0.89) predicted persistent AKI with good sensitivity and specificity (p=0.000). Serum and urine NGAL levels at admission correlated with severity (4-tier and Atlanta classification), APACHE and BISAP score and mortality (p<0.05).
