Standard anastomotic configuration for esophagogastric anastomosis is not conclusive. This study aimed to compare the short-term outcomes of end-to-end (ETE) cervical double-layer hand-sewn anastomoses with those of end-to-side (ETS) anastomoses for minimally invasive McKeown esophagectomy.


Between January 2016 and December 2017, the clinical data of 252 consecutive patients who underwent minimally invasive esophagectomy were reviewed retrospectively. The 252 patients comprised 130 patients in the ETS group and 122 patients in the ETE group. The same surgical procedures were applied in both groups, except for esophagogastric reconstruction. Short-term outcomes including leakage, stricture, reflux, operative features, and other surgical complications were analyzed for a comparison of the two configurations.


The ETS and ETE groups did not differ significantly in terms of leakage rate (P = 0.34), anastomotic stricture rate (P = 0.70), or postoperative reflux (P = 0.66). However, the ETS group had a longer operation time (P = 0.011), a longer anastomosis time (P < 0.001), and a longer postoperative hospital stay (P = 0.009) than the ETE group, and the postoperative gastric dilation rates were lower in ETE group than in the ETS group (P = 0.025). The two groups did not differ significantly in terms of other postoperative complications.


The major postoperative complications were comparable for the two anastomotic configurations. However, the patients with ETE anastomosis showed a favorable outcome in terms of a decreasing postoperative thoracic gastric dilation rate. End-to-end anastomosis also seemed to have slight advantages in terms of shorter operation and anastomosis times as well as a shorter postoperative hospital stay.
