    Background/AimsPostoperative respiratory hypofunction sometime ruins quality of life of patients with esophageal cancer. From 1993, we introduced transhiatal esophagectomy without thoracotomy as a less invasive surgery to prevent postoperative respiratory complications for patients who have relatively early stage of esophageal cancer and have preoperative respiratory complication, or who are older in age. In this study, postoperative long-term evaluation of respiratory functions of patients with esophageal cancer who underwent esophagectomy was performed.MethodologyAmong the patients with esophageal cancer who underwent esophagectomy in our hospital between 1993 and 1995, we selected 13 patients who underwent transhiatal esophagectomy (transhiatal group) and 9 patients who underwent transthoracic esophagectomy (transthoracic group). Conventional respiratory function tests (VC, vital capacity; FVC, forced vital capacity; FEV1, forced expiratory volume in 1 second; FEV1/FVC, ratio of FEV1 to FVC; PEF, peak expiratory flow) were compared between the two groups at 3, 6, and 12 months after operation.ResultsIn the transhiatal group, postoperative average values of VC, FVC, and FEV1 recovered 92%, 98%, and 93% of preoperative average values at 6 months after operation, while in the transthoracic group, the average values of VC, FVC, and FEV1 were still 78%, 78%, and 72% of preoperative average values at 6 months after operation. Postoperative respiratory complications were detected in 4 patients (transhiatal: 2 and transthoracic: 2). The recovery rates of VC, FVC, FEV1, FEV1/FVC, and PEF at 6 months after operation of these 4 patients were not different from those of 18 patients without postoperative respiratory complications.ConclusionsIn patients treated with transthoracic esophagectomy, postoperative respiratory hypofunctions continued over 6 months after surgery. However, postoperative respiratory complications may not be related with the long-term postoperative respiratory hypofunction in patients with esophageal cancer.
