In-hospital mortality after resection of biliary tract cancer in the United StatesOBJECTIVE: To assess perioperative mortality following resection of biliary tract cancer within the U.S. BACKGROUND: Resection remains the only curative treatment for biliary tract cancer. However, current data on operative mortality after surgical resections for biliary tract cancer are limited to small and single-center studies. METHODS: Using the Nationwide Inpatient Sample 1998-2006, a cohort of patient-discharges was assembled with a diagnosis of biliary tract cancer, including intrahepatic bile duct, extrahepatic bile duct, and gall bladder cancers. Patients undergoing resection, including hepatic resection, bile duct resection, pancreaticoduodenectomy, and cholecystectomy, were retained. The primary outcome measure was in-hospital mortality. Categorical variables were analyzed by chi-square. Multivariable logistic regression was performed to identify independent predictors of in-hospital mortality following resection. RESULTS: 31 870 patient-discharges occurred for the diagnosis of biliary tract cancer, including 36.2% intrahepatic ductal, 26.7% extrahepatic ductal, and 31.1% gall bladder. Of the total, 18.6% underwent resection: mean age was 69.3 years (median 70.0); 60.8% were female; 73.7% were white. Overall inpatient surgical mortality was 5.6%. Independently predictive factors of mortality included patient age >/=50 (vs./= 70 OR 9.03, 95% CI 2.86-28.56), the presence of identified comorbidities (congestive heart failure, OR 3.67, 95% CI 2.61-5.16; renal failure, OR 4.72, 95% CI 2.97-7.49), and admission designated as emergent (vs. elective; OR 1.82, 95% CI 1.39-2.37). CONCLUSION: Increased in-hospital mortality for patients undergoing biliary tract cancer resection corresponded to age, comorbidity, hospital volume, and emergent admission. Further study is warranted to utilize these observations in promoting early detection, diagnosis, and elective resection.

Surgical specialization and operative mortality in hepato-pancreatico-biliary (HPB) surgeryINTRODUCTION: Surgeon specialization has been shown to result in improved outcomes but may not be the sole measure of surgical quality in hepato-pancreatico-biliary (HPB) surgery. We attempted to determine which factors predominate in optimal patient outcomes between volume, surgeon, and hospital resources. METHODS: All non-transplant pancreatic (n = 7195) and liver operations (n = 4809) from the Nationwide Inpatient Sample (NIS) were examined from 1998-2005. Surgeons and hospitals were divided into two groups, transplant (TX) or non-transplant (non-TX), using the unique surgeon and hospital identifier of NIS. A logistic regression model examined the relationship between factors while accounting for patient and hospital factors. RESULTS: We identified 4,355 primary surgeons (165 TX, 4,190 non-TX) who performed HPB surgery in 675 hospitals across 12 different states. Non-TX surgeons performed the majority of pancreatic (97%) and liver procedures (81%). There was no difference in mortality after HPB surgery depending on surgeon specialty (p = 0.59). Factors for inpatient death after HPB surgery included increasing age, male gender, and public insurance (p < 0.05). In addition, surgery performed at a TX center had a 21% lower odds of perioperative mortality. DISCUSSION: Non-TX surgeons performed the majority of pancreatic and liver surgery in the US. Hospital factors like support of transplantation but not surgical specialty, appeared to impact operative mortality. Future regulatory benchmarks should consider these types of center-based facilities and resources to assess patient outcomes.
