National trends in technique use for esophagectomy: Does primary surgeon specialty matter?

Background: Cardiothoracic surgeons and general surgeons (including surgical oncologists) perform most esophagectomies. The purpose of this study was to explore whether specialty-driven differences in surgical techniques and the use of minimally invasive surgical approaches exist and are associated with postoperative outcomes after esophagectomy.
Methods: This was a retrospective review of the American College of Surgeons National Surgical Quality Improvement Program esophagectomy-targeted participant user file (2016-2018). Patients who underwent esophagectomy were sorted into cardiothoracic and general surgeon cohorts based on surgeon specialty. Perioperative characteristics and postoperative outcomes were compared using the χ ² analysis or independent t test. Multivariable logistic regression controlling for perioperative variables was performed to generate risk-adjusted rates of postoperative outcomes compared by surgical specialty.
Results: Of 3,247 patients included, 1,792 (55.2%) underwent esophagectomy by cardiothoracic surgeons and 1,455 (44.5%) by general surgeons as the primary surgeon. Cardiothoracic surgeons were more likely to use traditional minimally invasive surgical (P = .0004) or open approaches (P < .0001) and less likely to use robotic (P = .04) or a hybrid robotic and traditional approaches (P < .0001). Cardiothoracic surgeons performed more Ivor Lewis esophagectomies and fewer transhiatal and McKeown esophagectomies (P < .0001). After risk adjustment, there were no differences in rates of postesophagectomy complications, such as anastomotic leaks or positive margins, between cardiothoracic surgeons and general surgeons (all P > .05). However, cardiothoracic surgeons were more likely than general surgeons to treat anastomotic leaks with surgery rather than procedural interventions (odds ratio = 1.76; 95% confidence interval, 1.24-2.52).
Conclusion: Cardiothoracic surgeons and general surgeons use minimally invasive surgical subtypes differently when performing esophagectomy. However, there were no risk-adjusted differences in postoperative complications when compared by surgical subspecialty. Esophagectomy is being performed safely by surgeons with different specialties and training pathways.
