Initial experience from a large referral center with robotic-assisted Ivor Lewis esophagogastrectomy for oncologic purposes

We report our initial experience of patients undergoing robotic-assisted Ivor Lewis esophagogastrectomy (RAIL) for oncologic purposes at a large-referral center. A retrospective review of all consecutive patients undergoing RAIL from 2010-2011 was performed. Basic demographics were recorded. Oncologic variables recorded included: tumor type, location, postoperative tumor margins, and nodal harvest. Immediate 30-day postoperative complications also were analyzed. Fifty patients underwent RAIL with median age of 66 (range 42-82) years. The mean body mass index was 28.6 +/- A 0.7 kg/m(2); 54 % and the majority had an American Society of Anesthesiologists classification of 3. The mean and median number of lymph nodes retrieved during surgery was 20 +/- A 1.4 and 18.5 respectively. R0 resections were achieved in all patients. Postoperative complications occurred in 14 (28 %) patients, including atrial fibrillation in 5 (10 %), pneumonia in 5 (10 %), anastomotic leak in 1 (2 %), conduit staple line leak in 1 (2 %), and chyle leak in 2 (4 %). The median ICU stay and length of hospitalization (LOH) were 2 and 9 days respectively. Total mean operating time calculated from time of skin incision to wound closure was 445 +/- A 85 minutes; however, operative times decreased over time. Similarly, there was a trend toward lower complications after the first 29 cases but this did not reach statistical significance. There were no in-hospital mortalities. We demonstrated that RAIL for esophageal cancer can be performed safely and may be associated with fewer complications after a learning curve, shorter ICU stay, and LOH.
