An antireflux procedure was performed to prevent postoperative reflux. A posterior (Toupet) hemifundoplication was used in patients with a modestly dilated esophagus. And anterior (Dor) fundoplication was used with the most dilated esophagi, because a posterior fundoplication appeared to cause a relative outlet obstruction by excessively angling the gastroesophageal junction anteriorly.
I'm betting on the Toupet. My esophagus was hardly dilated at all in barium swallow.
