BACKGROUND: Mortality due to severe or necrotizing acute pancreatitis most often results from multiorgan dysfunction syndrome (MODS) occurring either early (within the first 14 days) or 2 weeks or more after the onset of symptoms due to septic complications. The aim of this study was to analyse the course of the disease in patients who died from severe acute pancreatitis.
METHODS: Between January 1994 and August 2000 details of 263 consecutive patients with acute pancreatitis were entered prospectively into a database. All patients were treated in an intermediate or intensive care unit.
RESULTS: The overall mortality rate was 4 per cent (ten of 263 patients). The mortality rate was 9 per cent (ten of 106) in patients with necrotizing disease. No patient died within the first 2 weeks of disease onset. The median day of death was 91 (range 15-209). Six patients died from septic MODS. Ranson score, Acute Physiology and Chronic Health Evaluation (APACHE) II score during the first week of disease, pre-existing co-morbidity, body mass index, infection and extent of necrosis were significantly associated with death (P<0.01for all parameters). However, only infection of the necrotic pancreas was an independent risk factor in the multivariate analysis.
CONCLUSION: Early deaths in patients with severe acute pancreatitis are rare, mainly as a result of modern intensive care treatment. Nine of the ten deaths occurred more than 3 weeks after disease onset. Infection of pancreatic necrosis was the main risk factor for death.

UNLABELLED: Several prior studies have suggested that 80% of deaths in acute pancreatitis occur late as a result of pan-creatic infection. Others have suggested that approx half of deaths occur early as a result of multisystem organ failure. The aim of the present study was to determine the timing of mortality of acute pancreatitis at a large tertiary-care hospital in the United States.
METHODS: Patients with a diagnosis of acute pancreatitis (ICD-9 code 577.0) admitted to Brigham and Women's Hospital from October 1, 1982 to June 30, 1995 were retrospectively studied to determine total mortality, frequency of early vs late deaths, and clinical features of patients with early (<or = 14 d after admission) or late deaths (>14 d after admission).
RESULTS: The overall mortality of acute pancreatitis was 2.1% (17 deaths among 805 patients). Eight deaths (47%) occurred within the first 14 d of hospitalization (median d 8, range 1-11 d), whereas 9 occurred after 14 d (median d 56, range 19-81). Early deaths resulted primarily from organ failure. Late deaths occurred postoperatively in 8 patients with infected or sterile necrosis and 1 patient with infected necrosis treated medically.
CONCLUSION: Approximately half of deaths in acute pancreatitis occur within the first 14 d owing to organ failure and the remainder of deaths occur later because of complications associated with necrotizing pancreatitis. Improvement in mortality in the future will require innovative approaches to counteract early organ failure and late complications of necrotizing pancreatitis.
