Abstract

Introduction: Bile duct injury (BDI) remains the dreaded complication of laparoscopic cholecystectomy (LC) over the last two decades. Although the Fundamentals of Laparoscopic Surgery (FLS) certification is now required for new applicants by the American Board of Surgery, the impact of FLS on procedure-specific outcomes is unknown. Moreover, the FLS content centers on fundamental education and not procedure-specific complication reduction such as BDI, magnifying the importance of understanding the educational impact of FLS on specific case types. This study reviewed the impact of FLS certification and other factors on the incidence of bile duct injury in a large insurance claims database.

Methods: In total, 53,632 LCs were reviewed from July 2009 to December 2010 from a large private payer claims database. Surgeon National Provider Identifier (NPI), FLS certification status, International Classification of Diseases, Ninth Revision (ICD-9) and Current Procedural Terminology (CPT) were available for each event. Each record was analyzed for evidence of any bile duct injury based on associated CPT or ICD-9 data in the claim record. Characteristics of the FLS+ and FLS− surgeon groups were analyzed by a separate reviewer blinded to clinical outcome on a large scale.

Results: A total of 53,632 LCs were reviewed; 1748 LC were performed by 441 FLS+ surgeons; and 58,870 LCs by 10,851 FLS- surgeons. (Some procedures involved more than one surgeon). Eighty-two BDIs were identified: 8 in the FLS+ and 74 in the FLS− group. The FLS+ group had a higher rate of BDI than the FLS− group (0.47 vs. 0.14 %, p = 0.0013); however, the FLS+ group was also younger (mean age 38.2 FLS+ vs. 50.4 years) and had significantly fewer years in practice (FLS+ = 6.1 vs. FLS− = 20.7, p = 0.0012). No other complications showed differences between the groups.

Conclusion: NPI can be used as a linking intermediary between skills certification and outcomes on claims databases. FLS certification was not associated with a reduction in bile duct injury in this analysis, but FLS+ surgeons were also younger and less experienced overall. Since FLS lacks content specific to BDI, large-scale validated training and assessment programs targeted at BDI prevention are needed to impact the rate of this complication during cholecystectomy.
