BackgroundAs an extensive surgery, minimally invasive esophagectomy (MIE) has advantages in reducing morbidity and improving quality of life for patients suffering from esophageal cancer. This study aims to investigate differences between MIE and open esophagectomy (OE) for considerations of the safety of procedures, rate of tumor resection, postoperative complications, and quality of life. This paper also tends to provide some references for MIE on esophageal cancer therapy.MethodsA retrospective data analysis was undertaken on 140 patients who either underwent MIE or OE for esophageal cancer with cervical anastomosis from March 2013 to May 2014 by our surgical team. Preoperative characteristics were analyzed for both groups. Differences in perioperative and oncologic outcomes were compared in operation time, intraoperative blood loss, lymph nodes retrieved, and R0-resection rate. Accordingly, a comparative analysis was conducted on complications namely anastomotic leakage, pulmonary infection, in-hospital mortality, and short-term (3 months) postoperative EORTC C30 Global health as well.ResultsA total of 140 patients (87 with MIE and 53 with OE) were enrolled and the two groups were homogeneous in terms of patient- and tumor-related data. There was no difference on postoperative ICU stay (21.15 ± 1.54 h vs 21.75 ± 1.68 h, p = 0.07) and R0-resection rate (100% vs 100%, p = 1.00). The operation time for MIE was significantly shorter (146.08 ± 17.35 min vs 200.34 ± 14.51 min, p <  0.0001), the intraoperative blood loss was remarkably saved (MIE vs OE, 83.91 ± 24.72 ml vs 174.53 ± 35.32 ml, P <  0.0001) and more lymph nodes were retrieved (MIE vs OE, 38.89 ± 4.31 vs 18.42 ± 3.66, P <  0.0001). There was no difference between the groups to postoperative complications and mortality. However, pulmonary infection in MIE was higher than in OE and the difference was not statistically significant (MIE vs OE, 20.75% vs 31.03%, P = 0.24). Complications such as in-hospital mortality and short-term (3 months) postoperative EORTC C30 Global health displayed no difference between both groups as well.ConclusionsThe number of lymph nodes and intraoperative blood loss were significantly ameliorated in MIE. A 4-5 cm longitudinal incision below the xiphoid process was made to create the gastric conduit under direct vision assisting in shortening the total operation time significantly.
