Case series results indicate that a surgical approach is superior to percutaneous drainage of pancreatic pseudocysts. To determine if this surgical advantage is persistent, national outcomes for both approaches were compared from 1997 through 2001. The National Inpatient Sample, a 20% sample of all nonfederal hospital discharges, was searched for patients who had a pancreatic pseudocyst diagnosis, an ICD-9 diagnosis code 577.2, and an ICD-9 procedure code of 52.01 for percutaneous drainage (PD) or 52.4 and 52.96 for the surgical approaches. Variables were compared by using either t test or chi2 analysis. Confounding variables were controlled for by linear or logistic regression models. No clinically significant demographic, comorbidity, and disease-specific severity-of-illness differences existed between the two groups. Significant differences in complications, length of stay (15+/-15 versus 21+/-22 days, P<0.0001), and inpatient mortality (5.9% versus 2.8%, P<0.0001) favored the surgical approach. In addition, endoscopic retrograde cholangiopancreatography use had a protective effect on mortality (odds ratio, 0.7), whereas percutaneous drainage had an increased risk of mortality (odds ratio, 1.4). This population-based study suggests that surgical drainage of pancreatic pseudocysts, particularly when coupled with use of endoscopic retrograde cholangiopancreatography, leads to decreased complications, length of stay, and mortality in comparison with percutaneous drainage.
