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.

Gastroduodenal artery aneurysm - A rare complication of traumatic pancreatic injury

Aneurysm of gastroduodenal artery （CDA） is rare. Most reported cases are due to pancreatitis and atherosclerosis; however, those following pancreatic trauma have not been reported. We encountered GDA aneurysm in a patient of blunt abdominal trauma, who had pancreatic contusion and retroduodenal air on contrast enhanced computed tomography of abdomen. Emergency laparotomy for suspected duodenal injury revealed duodenal wall and pancreatic head contusion, mild hemoperitoneum and no evidence of duodenal perforation. In the postoperative period, the patient developed upper gastrointestinal hemorrhage on day 5. Repeat imaging revealed GDA aneurysm, which was managed successfully by angioembolization. This case highlights, one, delayed presen- tation of GDA aneurysm after blunt pancreatic trauma and two, its successful management using endovascular technique.
