Abstract

Purpose: Using a circular stapler to create an anastomosis for esophagogastrostomy after esophagectomy is well accepted; however, it remains uncertain if the greater curvature (GC) or lesser curvature (LC) of the gastric conduit is better for the anastomosis. We conducted this prospective study to compare the integrity of esophagogastrostomy between the esophagus and the GC or LC side of the gastric conduit. Methods: The subjects of this study were 70 patients who underwent esophagectomy and were randomized to a “GC” group and an “LC” group (n = 35 each). The primary and secondary end points were anastomotic leakage (AL) and anastomotic stricture (AS), respectively. Results: The overall AL rate was 22.1%, without a significant difference between the groups. Stump leakage developed in eight of nine patients in the GC group, whereas leakage developed at the esophagogastric anastomosis in five of six patients in the LC group. The rate of stump leakage was significantly higher than that of esophagogastric AL in the GC group. The overall AS rate was 4.4%, with a significant difference between the groups (0% in the GC group vs. 9.1% in the LC group). Conclusions: AL rates were comparable in the two groups, but the sites of leakage were significantly different.
