This study aimed to compare stenosis rates between newly introduced 23- and 25-mm powered CSs in cervical esophagogastric anastomosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      From May 2022 to February 2024, 126 patients who underwent thoracoscopic McKeown esophagectomy with retrosternal gastric conduit reconstruction were retrospectively analyzed. They were categorized into the 23-mm (\n                      <jats:italic>n<\/jats:italic>\n                      = 52) and 25-mm (\n                      <jats:italic>n<\/jats:italic>\n                      = 74) CS groups. The primary endpoint was the comparison of anastomotic stricture rates.

The incidence of anastomotic stricture was 18.0% (7 cases) and 12.8% (5 cases) in the 23- and 25-mm CS groups, respectively (\n                      <jats:italic>p<\/jats:italic>\n                      = not significant [NS]). The incidence of anastomotic leakage and the leakage location revealed no significant differences between the two groups. A two one-sided test for equivalence was performed to compare the risk difference in stricture rates between the groups, resulting in a risk difference of 5.1% with a 90% confidence interval of \u2212\u00a00.087 to 0.191 and a p value of 0.041, suggesting potential equivalence.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In this study, 23- and 25-mm powered CSs achieved comparable anastomotic stricture rates in cervical esophagogastric anastomosis during McKeown esophagectomy.
