    Abstract:
    PURPOSE: The aim of this study was to investigate whether muscle sparing thoracotomy (MST) improved postoperative chest pain and an impairment of the postoperative pulmonary function in comparison with posterolateral thoracotomy (PLT). METHODS: Twenty-four patients with esophageal cancer who underwent PLT from September 2006 to August 2008 and 30 patients who underwent MST from September 2008 to August 2010 were selected as subjects of this study. Postoperative acute and chronic chest pain and the recovery of the pulmonary function were retrospectively compared between the two groups. RESULTS: The frequency of the additional use of analgesics was on days 3, 6, and 7 (mean 0.4 vs. 1.2, p = 0.027, 0.4 vs. 1.5, p = 0.007, and 0.2 vs. 1.2, p = 0.009, respectively) in the early postoperative period. The number of patients requiring analgesics at 1 and 3 months after surgery was significantly lower in the MST group than in the PLT group (13.3 vs. 58.3 %, p = 0.002, 10.0 vs. 50.0 %, p = 0.001, respectively). The postoperative vital capacity, expressed as a percentage of the preoperative value, 3 and 12 months after surgery was significantly higher in the MST group than in the PLT group (86.0 vs. 73.8 %, p = 0.028, 93.2 vs. 76.9 %, p = 0.002, respectively). CONCLUSION: Compared with PLT, MST might, therefore, reduce postoperative chest pain and offer a better recovery of pulmonary function in patients with esophageal cancer.
