The aims of the study were to compare the outcomes of biliary pancreatitis
after endoscopic and surgical treatment and define the demographic and clin
ical characteristics that affect the outcomes. All inpatients with biliary
pancreatitis followed at hospitals of the Department of Veterans Affairs du
ring 1988-1994 were included in a case-control study. Of 2075 patients with
biliary pancreatitis, 650 were first treated by biliary endoscopy and 1425
by cholecystectomy. Compared with cholecystectomy, biliary endoscopy was a
ssociated with older age, admission to nonsurgical service, more complicate
d pancreatitis, and choledocholithiasis. Seventy-one patients died. Death o
ccurred more often in older patients with multiple comorbid conditions and
complications of biliary pancreatitis. Overall length of hospital stay was
positively correlated with complications, choledocholithiasis, comorbidity,
and deferment of endoscopic or surgical procedure. After adjusting for oth
er confounding variables, both types of treatment resulted in similar death
rates and lengths of hospitalization. In conclusion, compared with cholecy
stectomy, biliary endoscopy is chosen preferentially in older patients with
choledocholithiasis or a complication of their pancreatitis. Despite such
selection bias, biliary endoscopy results in similar outcomes as surgery. E
arly intervention by either strategy reduces the length of hospital stay.
