術後にバルーンカテーテルを用いた食道入口部拡張訓練により経口摂取が可能となった口腔癌の1例 A postoperative case of oral cancer in which widening of the esophageal entrance with a balloon catheter enabled oral intake
In a patient with aspiration after the resection of oral cancer and reconstruction, we conducted swallowing rehabilitation by the balloon method to widen the esophageal entrance. The volume of air in the balloon catheter was gradually increased from 2 to 8 ml over the course of 10 days. Aspiration resolved with widening of the esophageal entrance, and oral intake became possible. The degree of maximal widening of the esophageal entrance during swallowing was examined with an image analysis system. After rehabilitation the degree of maximal widening of the esophageal entrance during swallowing increased by approximately 2 fold as compeared with before rehabilitation. Widening of the esophageal entrance during swallowing was maintained for 6 months postoperatively.<BR>These results suggested that the balloon method was useful for widening the esophageal entrance.
