Thoracoabdominal Esophagectomy: Then and Now

Abstract

BackgroundOpen approaches for esophagectomy are often still useful; of these, left thoracoabdominal esophagectomy (TAE) is poorly understood and often criticized. Hence, we examined TAE’s worldwide utilization, survival, and present-day use and outcomes at our institution compared with contemporary national averages. MethodsThe Worldwide Esophageal Cancer Collaboration database includes 8854 patients who underwent esophagectomy for cancer between 2005 and 2014, a period when TAE was our center’s most common approach. Two propensity score–matched models were constructed: worldwide TAE vs worldwide non-TAE (751 matched pairs); and our high-volume center TAE vs worldwide non-TAE (273 matched pairs). All-cause mortality was compared between matched groups. Institutional TAE data from 2017 to 2021 were assessed for present-day use and outcomes. ResultsWorldwide, propensity score–matched patients undergoing TAE had a median of 20 lymph nodes resected vs 17 after non-TAE (P < .0001). Five-year survival was 34% for worldwide TAE vs 42% for worldwide non-TAE groups (P = .04). Three-year matched survival was 52% for high-volume TAE compared with 54% for worldwide non-TAE groups (P = .1). From 2017 to 2021 at our institution, 90 (26%) of 346 esophagectomies were performed by TAE. Pneumonia developed in 5 patients (5.6%), with 88 patients (98%) alive at 30 days, comparable to contemporary averages of The Society of Thoracic Surgeons. ConclusionsWhen it is performed as the primary approach in high volumes, TAE can have comparable outcomes to non-TAE with low morbidity. At present, we find that TAE is most useful in patients with truncal obesity, prior abdominal operations, and locally advanced cardia tumors with potential for variable extent of resection.
