ABSTRACT

OBJECTIVES: To compare the characteristics and outcomes of patients presenting to hospital with alcohol-induced and gallstone-induced acute pancreatitis.

METHODS: Retrospective study of all patients with alcohol-induced or gallstone-induced pancreatitis during the period 1 June 2012 to 31 May 2016. The primary outcome measure was hospital mortality. Secondary outcome measures included hospital length of stay, requirements for intensive care unit admission, intensive care unit mortality, mechanical ventilation, renal replacement therapy, requirement of inotropes and total parenteral nutrition.

RESULTS: A total of 642 consecutive patients (49% alcohol; 51% gallstone) were included. No statistically significant differences were found between alcohol-induced and gallstone-induced acute pancreatitis with respect to hospital mortality, requirement for intensive care unit admission, intensive care unit mortality and requirement for mechanical ventilation, renal replacement therapy, inotropes or total parenteral nutrition. There was significant difference in hospital length of stay (3.07 versus 4.84; p < 0.0001). On multivariable regression analysis, Bedside Index of Severity in Acute Pancreatitis score (estimate: 0.393; standard error: 0.058; p < 0.0001) and admission haematocrit (estimate: 0.025; standard error: 0.008; p = 0.002) were found to be independently associated with prolonged hospital length of stay.

CONCLUSION: Hospital mortality did not differ between patients with alcohol-induced and gallstone-induced acute pancreatitis. The duration of hospital stay was longer with gallstone-induced pancreatitis. Bedside Index of Severity in Acute Pancreatitis score and admission haematocrit were independently associated with hospital length of stay.
