title: A comparison of short-term outcomes between Ivor-Lewis and McKeown minimally invasive esophagectomy.
abstract: BACKGROUND
  Only few comparative studies have been reported on the outcomes of minimally invasive esophagectomy (MIE) with intrathoracic anastomosis (MIE Ivor-Lewis) and MIE with cervical anastomosis (MIE McKeown) for patients with mid and lower esophageal cancer. The objective of this study is to compare the safety, feasibility, and short-term outcomes between two groups.
  
  
  METHODS
  Clinical and surgical data of patients with esophageal cancer who underwent either MIE Ivor-Lewis or MIE McKeown between January 2013 and October 2014 were retrospectively analyzed. Demographic characteristics, pathological data, operative procedures, and perioperative outcomes and survival in patients were compared between both groups.
  
  
  RESULTS
  Of the 72 patients included in this retrospective analysis, 32 underwent MIE Ivor-Lewis and 40 underwent MIE McKeown. Demographics, pathologic data, inpatient mortality, and surgical morbidity in both cohorts were almost identical. A significant difference was observed in Pulmonary complication (18.8% vs. 42.5%, P=0.032), Anastomotic leakage (9.4% vs. 30%, P=0.032), Anastomotic stenosis (12.5% vs. 35%, P=0.028), recurrent laryngeal nerve (RLN) injury (6.3% vs. 22.5%, P=0.034) between MIE Ivor-Lewis and MIE McKeown groups; however, no difference in operative time (312.6±82.0 vs. 339.4±80.0, P=0.249), blood loss (246.3±82.4 vs. 272.9±136.3, P=0.443), lymph nodes harvested (19.3±8.1 vs. 20.2±7.2, P=0.655) and 90-day mortality (3.1% vs. 5%, P=0.692) was observed between two groups.
  
  
  CONCLUSIONS
  The procedure of MIE Ivor-Lewis for esophageal cancer possesses advantages in perioperative outcomes and less complications compared with MIE McKeown.
