BackgroundMinimally invasive esophagectomy (MIE) for patients with esophageal cancer has recently spread worldwide. However, whether MIE is less invasive has not yet been fully evaluated.MethodsWe retrospectively analyzed data from 551 patients who underwent curative esophagectomy for esophageal cancer from 2005 to 2014: 145 patients underwent minimally invasive esophagectomy (MIE) and 406 patients underwent open transthoracic esophagectomy (OE). We compared postoperative CRP levels with propensity score matching. In addition, long-term outcomes were also compared between the groups.ResultsOperative time was significantly longer, and intraoperative blood loss was significantly less in the MIE group compared with the OE group. Although the incidence of postoperative complications was similar between the 2 groups, postoperative serum CRP levels during the first 3 and 5postoperative days and peak postoperative CRP levels were significantly lower after MIE versus OE (MIE vs. OE, median, 15.21 vs. 19.50mg/dl; P<0.001). The MIE group had significantly more favorable disease-free survival (DFS) and overall survival (OS) rates than the OE group (3-year DFS rate, 81.7 vs. 69.3%, log-rank P=0.021; 3-year OS rate, 89.9 vs. 79.2%, log-rank P=0.007). MIE was an independent prognostic factor for patients with esophageal cancer. The incidence of regional lymph node recurrence was lower in the MIE group.ConclusionsMIE significantly attenuated postoperative serum CRP levels compared with OE. MIE could contribute to improved survival.
