- W2493933518 abstract "98 Background: Postoperative pulmonary complications (PPCs) are the most common cause of serious morbidity following esophageal cancer resection and are associated with a poorer prognosis in esophagectomized patients (pts). We have recently reported that thoracoscopic esophagectomy (TSE) decreases PPC frequency. However, it remains unclear whether the frequency is further decreased by the combination with laparoscopic esophagectomy (LSE). This study aimed to clarify the combined effect of TSE with LSE on the prevention of PPCs and to determine the preventive factors for PPCs following esophagectomy using data from JCOG0502. Methods: JCOG0502 is a four-arm prospective study comparing esophagectomy with definitive chemoradiotherapy for T1bN0M0 cancer, with randomized and patient preference arms. The primary endpoint is overall survival, which will be analyzed in 2018. PPCs were defined as one or more of the following ≥ grade 2 postoperative morbidities per CTCAE v3.0: pneumonia, atelectasis, and acute respiratory distress syndrome. The use of TSE and/or LSE was decided at the surgeon’s discretion. Results: Totally, 379 pts (11 in the randomized and 368 in the patient preference arm) were enrolled between 2006 and 2013 from 37 institutions. Of the 210 pts who underwent esophagectomy, TSE was performed in 101 pts (TSE with laparotomy in 43 pts and TSE with LSE in 58 pts), while esophagectomy via thoracotomy was performed in 109 pts. PPCs occurred less often in pts who underwent TSE than esophagectomy via thoracotomy (15.8% vs 30.3%, p = 0.01); however, there was no difference in the frequency of PPCs between those who underwent TSE with laparotomy and TSE with LSE (16.3% vs 15.5%). In univariate analysis, both TSE (shown above) and less blood loss ( < 350 mL) were associated with the prevention of PPCs (16.3% vs 30.2%, p = 0.02). Multivariate analysis showed that TSE was associated with the prevention of PPCs [Odds ratio, 0.33; 95% confidence interval (0.12-0.88); p = 0.03]. Conclusions: This study indicated that TSE was the only independent preventive factor for PPCs following esophagectomy, and LSE had limited effectiveness in the prevention of PPCs when it is combined with TSE.
