Abstract

BACKGROUND:

Thoracic, cardiac, and general surgeons perform esophageal resections in the United States. This article examines the impact of surgeon subspecialty on outcomes after esophagectomy.

METHODS:

Esophagectomies performed between 1998 and 2008 were identified in the Nationwide Inpatient Sample. Surgeons were classified as thoracic, cardiac, or general surgeons if greater than 65% of their operative case mix was representative of their specialty. Surgeons with less than 65% of a specialty-specific case mix served as controls. Regression equations calculated the independent effect of surgeon specialty, surgeon volume, and operative approach (transhiatal versus transthoracic) on outcomes.

RESULTS:

Of the 40,589 patients who underwent esophagectomies, surgeon identifiers were available for 23,529 patients. Based on case mix, thoracic, cardiac, and general surgeons performed 3,027 (12.9%), 688 (2.9%), and 4,086 (17.4%) esophagectomies, respectively. Operative technique did not independently affect risk-adjusted outcomes-mortality, morbidity, and failure to rescue (defined as death after a complication). Surgeon volume independently lowered mortality and failure to rescue by 4% (p ≤ 0.002 for both), but not complications (p = 0.6). High-volume hospitals (>12 procedures/year) independently lowered mortality (adjusted odds ratio [AOR], 0.67, 95% confidence interval [CI], 0.46-0.96), and failure to rescue (AOR, 0.64; 95% CI, 0.44-0.94). Esophageal resections performed by general surgeons were associated with higher mortality (AOR, 1.87; 95% CI 1.02-3.45) and failure to rescue (AOR, 1.95; 95% CI, 1.06-3.61) but not complications (AOR, 0.97; 95% CI, 0.64-1.49).

CONCLUSIONS:

General surgeons perform the major proportion of esophagectomies in the United States. Surgeon subspecialty is not associated with the risk of complications developing but instead is associated with mortality and failure to rescue from complications. Surgeon subspecialty case mix is an important determinant of outcomes for patients undergoing esophagectomy.
