title: Minimally Invasive Esophagectomy: Esophagogastric Anastomosis Using the Transoral Orvil for the End-to-Side Ivor-Lewis Technique.
abstract: OBJECTIVE
  : Minimally invasive esophagectomy (MIE) can be performed a variety of ways using different techniques for the anastomosis. End-to-end anastomosis (EEA) transoral circular staplers have traditionally been used in gastric bypass surgery with good success. An evaluation of the safety and utility of the EEA transoral circular stapler for esophageal anastomoses in MIE is reviewed.
  
  
  METHODS
  : A retrospective chart review of all patients who underwent transthoracic MIE with EEA-stapled transoral anastomoses between January 2008 and May 2009 was performed. Patient demographics, indication for esophagectomy, perioperative treatments, intraoperative data, postoperative complications, hospital length of stay, and in-hospital mortality were evaluated.
  
  
  RESULTS
  : Twenty-six consecutive patients underwent MIE with EEA circular-stapled transthoracic anastomoses. Twenty-three were male with a mean age of 64 years (32-88). Indications for esophagectomy included esophageal cancer (24), high-grade dysplasia (1), and refractory stricture (1). Fifteen patients (63%) had neoadjuvant chemotherapy and radiation. There were no conversions to open thoracotomy or laparotomy. Mean operative time was 6.0 hours. Eight patients (31%) suffered postoperative complications; including leak from the gastric conduit staple line requiring operative intervention (1), postoperative bleeding requiring multiple transfusions (1), aspiration pneumonia (1), acute respiratory distress syndrome (1), myocardial infarction (1), chylothorax (1), and anastomotic stricture (2). Median hospital length of stay was 9 days (range 6-43). There were no in-hospital mortalities.
  
  
  CONCLUSIONS
  : In our series, the EEA circular stapler seems technically feasible and relatively safe for an intrathoracic anastomosis in MIE.
