Extra-pancreatic complications,especially hemodialysis predict mortality and length of stay,in ICU patients admitted with acute pancreatitis

Background and aims:Patients in the intensive care unit(ICU)with acute pancreatitis(AP)are at risk for extra-pancreatic complications given their severe illness and prolonged length of stay.We sought to determine the rate of extra-pancreatic complications and its effect on length of stay(LOS)and mortality in ICU patients with AP.Methods:We performed a retrospective cohort study of ICU patients admitted to a tertiary-care center with a diagnosis of AP.A total of 287 ICU patients had a discharge diagnosis of AP,of which 163 met inclusion criteria.We calculated incidence rates of extra-pancreatic complications and performed a univariate and multi-variable analysis to determine predictors of LOS and mortality.Results:There were a total of 158 extra-pancreatic complications(0.97 extra-pancreatic complications per patient).Ninetyfive patients had at least one extra-pancreatic complication,whereas 68 patients had no extra-pancreatic complications.Patients with extra-pancreatic complications had a significantly longer LOS(14.7 vs 8.8 days,p<0.01)when controlling for local pancreatic complications.Patients with non-infectious extra-pancreatic complications had a higher rate of mortality(24.0%vs 16.2%,p=0.04).Patients requiring dialysis was an independent predictor for LOS and mortality(incidence risk ratio[IRR]1.73,95%confidence interval[CI]:1.263–2.378 and IRR 1.50,95%CI 1.623–6.843,p<0.01)on multi-variable analysis.Coronary events were also a predictor for mortality(p=0.05).Other extra-pancreatic complications were not significant.Conclusions:Extra-pancreatic complications occur frequently in ICU patients with AP and impact LOS.Patients with noninfectious extra-pancreatic complications have a higher mortality rate.After controlling for local pancreatic complications,patients requiring dialysis remained an independent predictor for LOS and mortality.

Prognosis of cancer with branch duct type IPMN of the pancreas

AIM:To examine the coexistence of metachronous and synchronous cancer in branch duct intraductal papillary mucinous neoplasms of the pancreas (IPMN).METHODS: We reviewed the records of 145 patients with branch duct IPMN between January 1991 and April 2008 and assessed the relationship between IPMN and intraor extra-pancreatic carcinoma and the outcome of IPMN.RESULTS: The mean observation period was 55.9 ± 45.3 mo. Among the 145 patients, the frequency of extra-pancreatic cancer was 29.0%. The frequency of gastric cancer, colon cancer, breast cancer, and pan-creatic cancer were 25.5%, 15.7%, 13.7%, and 9.8%, respectively. Twenty (13.8%) of the patients died. The cause of death was extra-pancreatic carcinoma in 40%,pancreatic cancer in 25%, IPMN per se in 20%, and benign disease in 15% of the patients.CONCLUSION: The prognosis for IPMN depends not on the IPMN per se, but on the presence of intraor extra-pancreatic cancer.
