title: Motility studies of the cervical esophagus with intrathoracic gastric conduit after esophagectomy.
abstract: Gastric emptying, upper esophageal sphincter pressure and intrathoracic gastric motility were studied in esophagectomized patients, ten with a gastric conduit in the posterior mediastinum and ten with a conduit in the retrosternal space. In addition, the clinical state was reassessed more than 6 months after esophageal reconstruction. Gastric emptying, assessed with Tc-99m Sn colloid in a semisolid test meal, did not differ between the two groups. In manometric studies a high-pressure zone distal to the upper esophageal sphincter was associated with dysphagia. A high-pressure zone at the anastomosis was found in 60% of the retrosternal group and 20% of the posterior mediastinal group. As regards food intake, the posterior mediastinal route seems to be preferable in esophageal replacement, since it permits more physiologic motility of the conduit.
