Abstract
to describe the clinical practice and the factors associated with length of hospital stay in mild acute pancreatitis. we present a retrospective observational study that includes a series of patients admitted to our hospital between January 2007 and December 2009 due to mild acute pancreatitis. Baseline data, treatments and examinations were collected. Variables associated with the length of hospital were determined using a Cox proportional hazards model. 232 patients were included (median age 74.3 years, bedside index for severity in acute pancreatitis score 1, comorbidity Charlson score 1, 52.6 % male). 75.9 % were admitted to the gastroenterology department. Oral diet was reintroduced at 3 (0-11) days and 28 patients (12 %) were intolerant to oral re-feeding. Abdominal ultrasound, a magnetic resonance cholangiopancreatography, endoscopic ultrasound, a computed tomographic scan, and endoscopic retrograde cholangiopancreatography were performed in 92.2, 34.5, 9.5, 28.4 and 14.7 % of admissions, respectively. The length of hospital stay was 8 (1-31) days. The variables independently associated with length of admission were: Charlson index > or = 2 (hazard ratio-HR-1.4, 95 % confidence interval-CI- 1.06-1.84; p: 0.017), admission in gastroenterology department (HR 0.67, 95 % CI 0.49 to 0.93; p: 0.016), fasting period > or = 3 days (HR 1.37, 95 % CI 1.05-1.78; p: 0.02), intolerance to oral re-feeding (HR 1.8, 95 % CI 1.17-2.77; p: 0.007), performance of computed tomographic scan (HR 2.05, 95 % CI 1.49-2.82; p < 0.001), magnetic resonance cholangiopancreatography (HR 1.87, 95 % CI 1.42-2.49; p < 0.001) and endoscopic retrograde cholangiopancreatography (HR 2.23, 95 % CI 1.51-3.3; p < 0.001). the variables associated with length of hospital stay were comorbidity, department in charge, fasting period, food intolerance and complementary explorations.
