Costs and utilization of intraoperative cholangiography.

BACKGROUND: Routine intraoperative cholangiography (IOC) has been advocated as a viable strategy to reduce common bile duct injury (CDI) during cholecystectomy. This is predicated, in part, on the low cost of IOC, making it a cost-effective preventive strategy. Using billed hospital charges as a proxy for costs, we sought to estimate costs associated with the performance of IOC. METHODS: The 2001 National Inpatient Survey (NIS) database was assessed for IOC utilization and associated charges. Average charges for hospital admission where the primary procedure was laparoscopic cholecystectomy were compared for those associated with and without the performance of IOC. RESULTS: Eighteen percent of cholecystectomies were performed in facilities that never perform IOC. Routine IOC (defined as >75% of cholecystectomies performed in any one hospital having a concomitant IOC) was performed in only 11% of hospitals. In the remaining 71% of hospitals, selective IOC was performed. IOCs were associated with US $706-739 in additional hospital charges when performed in conjunction with laparoscopic cholecystectomy. We project a cost of US $371,356 to prevent a single bile duct injury by using routine cholangiography. CONCLUSION: We conclude that only a minority of hospitals performs cholecystectomies with routine IOC. Because of the significant amount of hospital charges attributable to IOC, routine IOC is not cost-effective as a preventative measure against bile duct injury during cholecystectomy.

Indications for selective intraoperative cholangiography.

The indications for selective intraoperative cholangiography (IOC) include a clinical history of jaundice, pancreatitis, elevated bilirubin level, abnormal liver function test results, increased amylase levels, a high lipase level, or dilated common bile duct on preoperative ultrasonography. Although these clinical features are widely accepted as indications for IOC, they have not been tested for their ability to predict choledocholithiasis. Charts were reviewed for a 6-month time period in 2003 at Parkland Memorial Hospital for all patients undergoing cholecystectomy. Univariate analysis and logistic regression were used to determine which factors predicted choledocholithiasis. Of the 572 patients undergoing cholecystectomies during the study period, 189 underwent IOC and common bile duct stones were found in 57. Only preoperative hyperbilirubinemia or ultrasonograph identification of common bile duct dilation reliably predicted choledocholithiasis. There were 13 cases of choledocholithiasis that would not have been identified by preoperative hyperbilirubinemia or an enlarged common bile duct. However, common bile duct stones were clinically significant in only 2 of the 13 cases. One of these was treated with postoperative endoscopic retrograde cholangiopancreatography, and the other was treated with laparoscopic common bile duct exploration. Preoperative identification of a dilated common bile duct or elevated bilirubin levels can be the sole criteria for performing IOC on a selective basis in patients without malignancy. Reliance on a history of remote jaundice, pancreatitis, elevated liver function test values, or pancreatic enzymes results in unnecessary IOCs.

Health care access and poverty do not explain the higher esophageal cancer mortality in African Americans.

BACKGROUND: Esophageal cancer mortality is increased in African Americans relative to white patients. The reasons for this are unknown but are thought to be related to inadequate access to health care secondary to a higher poverty rate in African American populations. METHODS: The National Health Interview Survey database for years 1986 to 1994 were combined and linked to the National Death Index. Individuals who died from esophageal carcinoma were assessed in the combined database, thus enabling detailed analysis of their socioeconomic status, race, and health care access. RESULTS: Poverty was 4-fold more frequent in African Americans who died from esophageal carcinoma than whites. Despite poverty, African American patients' access to health care was good and was not statistically related to increased mortality. CONCLUSIONS: Although the esophageal carcinoma mortality rate is higher in African Americans than in whites, it is not clearly related to the presence of poverty or to limited health care access. The higher mortality may be related to lifestyle differences, environmental exposure, or difference in disease biology, but it is not related exclusively to socioeconomic factors.
