Modified Collard versus end-to-side hand-sewn anastomosis for cervical anastomosis after McKeown esophagectomy.

A modified Collard cervical esophagogastric anastomosis was associated with lower rates of anastomotic stricture and dysphagia, compared with ETS hand-sewn anastomosis. However, the modified Collard anastomosis is accompanied by an increased anastomotic leakage rate.
