Minimally Invasive Ivor-Lewis Esophagectomy (MIILE): A Single-Center Experience

With the development of minimally invasive procedures, minimally invasive Ivor-Lewis esophagectomy (MIILE) has been proposed as a safe and feasible surgical choice for the treatment of esophageal cancer. This retrospective study evaluated MIILE results from a single medical center. A total of 619 patients were selected as candidates for Ivor-Lewis esophagectomy from December 2011 to May 2015, in which 334 patients accepted MIILE and 285 patients accepted open Ivor-Lewis esophagectomy (OILE). General characteristics, surgical data, complication rates, and survival were analyzed. Differences in general characteristics between groups were not significant. Intraoperative blood loss (P < 0.01), postoperative volume of drainage for the first day (P < 0.01), time to drain removal (P ≤ 0.01), wound infection rate (P = 0.04), and length of hospital stay (P < 0.01) were significantly reduced in the MIILE group. There were no statistically significant differences in general morbidity (P = 0.56), the total swept lymph nodes (P = 0.47), mortality (P = 0.34), and survival rate at 3 years (P = 0.63). MIILE is a safe and feasible method for the treatment of esophageal cancer, in which good outcomes were reported and some advantages were found over the open procedure.
