title: The short-term outcome of three-field minimally invasive esophagectomy for Siewert type I esophagogastric junctional adenocarcinoma.
abstract: BACKGROUND
  The incidence of esophagogastric junctional adenocarcinoma is increasing, and the surgery is associated with high mortality and morbidity rates. This study aims to evaluate whether three-field minimally invasive surgery promotes outcome as compared with three-incision open surgery.
  
  
  METHODS
  From January 1, 2009, to March 1, 2012, 114 consecutive patients with Siewert type I esophagogastric junctional adenocarcinoma were involved in this retrospective study. Patients were randomly assigned by a computer-generated randomization sequence to receive either three-incision open esophagectomy or minimally invasive esophagectomy. Details concerning patients and tumor characteristics, surgical procedures, and postoperative outcomes were collected and compared.
  
  
  RESULTS
  Totally, 59 patients were involved in the open esophagectomy group and 55 in the minimally invasive esophagectomy group. The incidence of pulmonary morbidity (9.09% versus 28.81%) and vocal cord paralysis (0% versus 15.25%) in the minimally invasive group was significantly less than that in the open esophagectomy group. Furthermore, the postoperative life quality in the minimally invasive group was better than that in the open group. Survival at 2 years was 83.6% for the minimally invasive group (46 of 55 patients) and 79.7% for the open esophagectomy group (47 of 59 patients).
  
  
  CONCLUSIONS
  Minimally invasive esophagectomy could lead to a significant improvement of the short-term benefits for patients with Siewert type I esophagogastric junctional adenocarcinoma.
