Esophagectomy: Comparison of Short-Term Outcomes between Single-versus Two-Team Approach

Literature about combining expertise of two specialties in esophageal cancer surgery is limited. We present the experience at a single institute comparing single-team (ST) versus two-team (TT) approach combining thoracic and abdominal surgeons. This is a retrospective study from a single tertiary care center. Data were collected from electronic medical records. Patients undergoing esophagectomy for esophageal cancer from November 2006 until August 2014 were included. The primary outcome measured was 30-day postoperative morbidity, secondary outcomes measured were operative time, intraoperative blood loss, and 30-day mortality. Results are reported as mean with an interquartile range. Forty-nine patients underwent esophagectomy by an ST and 51 patients by TT. Patient demographics, tumor characteristics, stage, pathology, and use of neoadjuvant therapy were comparable between groups. Charlson comorbidity index was significantly higher in TT group [3 (2, 4) vs 2 (2, 3), P = 0.02]. The TT group had a significantly shorter operative time compared to the ST group [304 (252,376) minutes vs 438 (375, 494] minutes, P < 0.0001). Intraoperative blood loss was 300 (200, 550) mL for the TT group and 250 (200,400) mL for the ST group (P = 0.29). There was no difference in 30-day postoperative morbidity (68.6% for TT, 59.2% for ST, P = 0.32) and mortality (2% each, P = 1) between the two groups. In conclusion, the operative time by the TT approach was significantly shorter than the ST approach with comparable postoperative morbidity and mortality. Long-term follow-up is needed to study this approach's effect on long-term survival.
