Transthoracic or Transhiatal Resection for Middle- and Lower-Third Esophageal Carcinoma?

Abstract

Transthoracic esophagectomy (TTE) and transhiatal esophagectomy (THE) are two common methods of resection for esophageal cancer. Although many studies have been performed in Western countries, there are still controversies over which method is the better procedure. In this study, postoperative improvement in dysphagia and the degree of postoperative pain were compared. The cases of 50 patients undergoing TTE and 23 undergoing THE for esophageal cancer between March 1997 and October 2002 were retrospectively reviewed. The location of the lesion, clinical stage (TNM), operative time, operative blood loss, hospital stay, complications, number of lymph nodes dissected, and survival duration were recorded. Pre- and postoperative dysphagia scores and postoperative pain perception (using a visual analog scale) were analyzed. Preoperative clinical stage and lesion site were not significantly different in the TTE and THE groups. The operative time was longer and the number of lymph nodes removed was larger in the TTE group. However, there were no differences in operative blood loss, hospital stay, complications, survival duration, and improvement in dysphagia. Pain perception in the THE group was significantly better than that in the TTE group. THE is a safe and rapid procedure, with recovery and survival periods similar to those for TTE. Both patient groups enjoyed the same ability to eat. Therefore, THE is an acceptable alternative to TTE for patients with middle- and lower-third esophageal cancer. Moreover, THE caused much less postoperative pain than TTE, which made patients more comfortable.
