Background: Neoadjuvant chemoradiation therapy (NT) has become standard of care for patients with locally advanced esophageal cancer. In selected patients, robotic-assisted Ivor Lewis esophagectomy (RAIL) is a safe and feasible operative strategy in the management of esophageal cancer. This study was designed to determine potential differences in peri-operative morbidity and short term outcomes in patients with esophageal cancer treated with RAIL with or without NT. Methods: A retrospective review of consecutive patients with esophageal cancer who underwent RAIL esophagectomy between October 2010 and June 2012 with and without NT was performed. Clinical and pathological variables were analyzed with two-sided student t-test assuming equal variance. Data were considered significant at a p-value <0.05. Results: Eighty-nine patients underwent RAIL during the study period. Seventy-seven patients (87%) received NT and twenty-two patients did not (13%). The median age was 66 years (range 44 – 84) and the median BMI was 28 kg/m2(range 16.7 – 40.1). All patients had a R0 resection. There were no differences in the mean estimated blood loss (149 vs.153 mL; p = 0.52) and mean operative times (434 vs. 427 minutes; p = 1.0). There were no differences in the incidence of pneumonia or atrial fibrillation, lengths of stay in the ICU, or length of hospitalization. In total, there were two anastomotic leaks and one leak from the gastric conduit. The anastomotic leaks occurred in the group that did not receive NT and the gastric conduit leak occurred in the group that received NT. There were no mortalities in either group. There was no difference in the mean number of lymph nodes harvested in the NT group (22 ± 11 vs. 20 ± 8, p = 0.41). Conclusions: RAIL can be safely performed following neoadjuvant chemoradiation therapy.In this series there were similar perioperative, morbidity and short-term mortality outcomes in patients who received NT compared with RAIL alone. Longer follow-up is required in order to determine long term oncologic outcome.
