title: Risk Factors and Outcome for Massive Intra-Abdominal Bleeding Among Patients With Infected Necrotizing Pancreatitis.
abstract: The incidence of acute bleeding is reported to be 13.5% in patients with acute necrotizing pancreatitis. However, of all the bleeding events, intra-abdominal bleeding was less studied in the literature and its risk factors have not been well defined yet. The purpose of the present study was to investigate the risk factors for massive intra-abdominal bleeding among the patients with infected necrotizing pancreatitis and assessed the outcome of these patients. Both univariate and multivariate logistic regression models were applied for evaluating risk factors for intra-abdominal bleeding using 33 indices, including age, sex, etiology of acute pancreatitis (AP), APACHE II score, etc. Outcome assessments such as mortality, hospital and intensive care unit (ICU) durations, and cost were also compared between patients with or without intra-abdominal bleeding. Acute kidney injury (AKI) (odds ratio [OR]: 7.54, 95% confidence interval [CI]: 2.53-22.52, P < 0.001) and number of operation (OR: 8.84, 95% CI: 2.01-38.86, P = 0.004) were 2 predictors for massive intra-abdominal bleeding in the patients with infected necrotizing pancreatitis. In addition, AP patients with intra-abdominal bleeding also showed significantly higher mortality rate, prolonged hospital and ICU durations, more complications and invasive treatments, as well as increased cost. Our study revealed that AKI and multiple operations were 2 critical factors increasing the risk of intra-abdominal bleeding among patients with infected necrotizing pancreatitis. Additionally, massive intra-abdominal bleeding was also associated with poor prognosis.
