SSI is associated with detriment to patient and graft survival following renal transplantation. The prevalence of SSI is higher among obese recipients, but those who avoid SSI have comparable outcomes to nonobese recipients. These findings redemonstrate the importance of SSI prevention following renal transplantation.

Summary We sought to estimate the effect of smoking on the biliary complication rate following orthotopic liver transplantation. We retrospectively evaluated the records of liver transplant recipients at our center from July 1, 1999 to October 26, 2007. Using Cox proportional hazards models, we estimated the time to the earliest biliary complication (leak or stricture) based on smoking exposure, as active, former, or lifetime nonsmoker, adjusting for other clinical factors. Overall, 409 liver transplant recipients were evaluated. The overall biliary complication rate was 37.7% (n = 154). Biliary complications included 66 anastomotic leaks, 60 anastomotic strictures, and 28 nonanastomotic lesions. ERCP was the primary diagnostic modality (n = 112). 18.1% of liver transplant recipients were active smokers (n = 74) and 42.8% were former smokers (n = 175). Active smokers were at greatest risk for biliary complications on unadjusted analysis (P = 0.022). After multivariable adjustment, active smokers had a 92% higher rate of biliary complication rates compared with lifetime nonsmokers (HR 1.92, 95% CI 1.07–3.43), but no difference was noted in the rate of complication resolution. Smoking clearly portends a significant risk of biliary complications following liver transplantation. Smoking status should be clearly defined when evaluating transplant candidacy and in counseling patients with cirrhosis.
