Background: We compared oncologic and surgical outcome between minimally invasive esophagectomy (MIE) and the Ivor Lewis-type open approach (OE) in the treatment of locally advanced esophageal adenocarcinoma (EAC).
Materials and methods: Of 284 patients undergoing surgery for EAC between 2003 and 2013, the 153 selected with locally advanced EAC were 74 MIEs and 79 OEs [median age, 66 for MIE, 63 for OE (p = 0.009)]. Neoadjuvant therapy was given to 82% of MIEs and 78% of OEs. In the OE group, 86% was male, and in the MIE group, 78%. Data assessed were oncologic, intraoperative, and postoperative.
Results: Mortality at 30 days was 3% for MIE and 1% for OE; and 90-day mortality was 4% for MIE and 5% for OE. The complication rate for MIE was 50%, and 60% for OE (p = 0.181). The pneumonia rate was 18% for MIE and 19% for OE; leak rate was 7% for MIE and 6% for OE; conduit necrosis was 0 for MIE and 3% for OE; and rate of airway-conduit fistula was 3% for MIE and 1 % for OE. Median blood loss (MIE 300 vs. OE 800, p < 0.0001), overall stay (MIE 13 vs. OE 14, p = 0.040), and harvested lymph nodes (MIE 20 vs. OE 22, p = 0.021) all were in favor of MIE. Median ICU stay and operative time did not differ. Neither did overall (OS) nor recurrence-free (RFS) 3-year survival differs significantly (MIE 64% vs. OS OE 49%, MIE 57% vs. RFS OE 53%).
Conclusions: In our institution, MIE appears to produce oncologic and survival results similar to those of OE. Shorter length of stay and less operative blood loss may reduce costs for MIE.
