Abstract
Biliary tract disease remains a common indication for operative intervention. The incidence of concurrent biliary tract disease (>2 biliary tract disease processes) is unknown and the impact of more than one biliary tract diagnosis on outcomes remains to be defined. The objective of this study was to determine the effect of concurrent biliary tract disease on conversion rate and outcomes after laparoscopic cholecystectomy. A 5-year retrospective analysis of all patients who underwent a laparoscopic cholecystectomy was performed comparing those with a single biliary diagnosis to patients with concurrent biliary tract disease. Variables analyzed were conversion to open cholecystectomy, incidence of bile duct injury, use of endoscopic retrograde cholangiopancreatography and/or intraoperative cholangiogram, length of surgery, and duration of hospitalization. The incidence of concurrent biliary tract disease was 9 per cent and a conversion to open cholecystectomy was performed in 16 per cent of patients. After adjusting for confounding factors, concurrent biliary tract disease was predictive of conversion (odds ratio 1.6, 95% confidence interval 1.1–2.3, P = 0.03) and bile duct injury (odds ratio 2.5, 95% confidence interval 0.8–5, P = 0.01). Concurrent biliary tract disease patients were more likely to undergo intraoperative cholangiogram or endoscopic retrograde cholangiopancreatography, as well as longer operation and length of stay.
