BACKGROUND/OBJECTIVES: After the creation of the moderately severe acute pancreatitis (MSAP) category in the Revised Atlanta Classification in 2012, predictors to identify these patients early have not been identified. The MSAP category includes patients with (peri)pancreatic necrosis, fluid collections, and transient organ failure in the same category. However, these outcomes have not been studied to determine whether they result in similar outcomes to merit inclusion in the same severity. METHODS: Retrospective, review of 514 consecutive, direct admissions for acute pancreatitis from 2010 to 2013. Multivariate logistic regression identified predictors of MSAP. RESULTS: Persistent SIRS was the best prognostic marker of MSAP with AUC 0.72. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for persistent SIRS to predict MSAP are: 55%, 88%, 40%, 93%, and 84%. Patients with necrosis had significantly longer length of stay (LOS) (p = 0.0001) and higher rates of ICU admission (p = 0.02) compared with patients with transient organ failure. Compared to those with acute fluid collections, patients with necrosis had longer LOS (p < 0.0001), higher rates of ICU admission (p = 0.0005), required more interventions (p = 0.001), and demonstrated higher mortality (0.003). DISCUSSION: Moderately severe pancreatitis can be distinguished from mild pancreatitis on the basis of persistent SIRS but cannot be accurately distinguished from severe pancreatitis in the first 48 h (Peri)pancreatic necrosis demonstrates significantly more morbidity compared to the other components of MSAP of fluid collections and transient organ failure.

BACKGROUND: In a population-based study, we examined recurrence rates of acute pancreatitis (AP) after cholecystectomy performed to prevent recurrences of AP. METHODS: We abstracted data from medical records of all Olmsted county residents who underwent cholecystectomy at Mayo Clinic for the management of presumed gallstone or idiopathic AP between 1990 and 2005 (n = 239). Based on (i) significantly elevated liver enzymes (≥threefold increase of alanine aminotransferase or aspartate aminotransferase) on day 1 and (ii) the presence of gallstones/sludge in the gall bladder, we categorized patients into 4 groups: A (i + ii), B (i but not ii), C (ii but not i), and D (neither i nor ii). Recurrence rates of AP after cholecystectomy were determined in all groups. RESULTS: The median follow-up after cholecystectomy was 99 months (range, 8-220). AP recurred in 13 of 142 patients (9%) in group A, 1 of 17 patients (6%) in group B, 13 of 57 patients (23%) in group C, and 14 of 23 patients (61%) in group D (P < .0001 D vs. all other groups and P = .001 C vs. groups A and B). No difference was seen in recurrence rates in groups A vs. B (P = 1.0). Recurrences were more frequent in patients with normal liver enzymes (A + B vs. C + D; P = .000003) and in patients without sonographic evidence of gallstones/sludge (A + C vs. B + D; P = .0008). CONCLUSION: When AP is associated with significantly elevated liver enzymes on day 1, recurrence rates after cholecystectomy are low (9%). However, postcholecystectomy recurrence rates of AP are high in those without such laboratory abnormalities (34%), especially in those without gall bladder stones/sludge (61%) on abdominal ultrasonography. Our results raise doubts about the efficacy of cholecystectomy to prevent recurrent AP in patients with the absence of either a significant elevation of liver tests on day 1 of AP or gallstones and/or sludge in the gall bladder on initial ultrasound examination.
