This study investigated the association between perioperative tongue pressure and postoperative aspiration in patients with esophageal cancer who underwent thoracoscopic-laparoscopic esophagectomy. The results showed that perioperative changes in tongue pressure, age, and postoperative recurrent laryngeal nerve palsy were significantly associated with aspiration. Decreased tongue pressure was identified as a modifiable predictor of aspiration.
Despite the increasing use of minimally invasive esophagectomies, aspiration pneumonia remains the most serious complication. This study clarified the association between perioperative tongue pressure and postoperative aspiration after thoracoscopic-laparoscopic esophagectomy in patients with esophageal cancer. This retrospective, single-center, observational study evaluated data of 216 patients scheduled for thoracoscopic-laparoscopic esophagectomy. Tongue pressure was measured before the procedure and on postoperative day 6; perioperative changes were assessed. Patients were divided into non-aspiration and aspiration groups according to penetration-aspiration scale scores. Hierarchical and stratified logistic regression analyses were performed to identify factors associated with aspiration. Receiver operating characteristic curves were used to assess the cut-off value of perioperative changes in tongue pressure for aspiration. Perioperative changes in tongue pressure (odds ratio 0.92; 95% confidence interval 0.88-0.96, P < 0.001), age (odds ratio 1.07; 95% confidence interval 1.01-1.13, P = 0.013), and postoperative recurrent laryngeal nerve palsy (odds ratio 3.04; 95% confidence interval 1.15-8.03, P = 0.025) were significantly associated with aspiration. The cut-off value of perioperative changes in tongue pressure for postoperative aspiration was - 6.58%. In addition, decreases in tongue pressure were associated with aspiration regardless of recurrent laryngeal nerve palsy and age. The perioperative decrease in tongue pressure, higher age, and postoperative recurrent laryngeal nerve palsy were significant factors strongly associated with aspiration in the acute phase post-esophagectomy. Decreased tongue pressure is the only intervenable predictor of aspiration. Rehabilitation for preventing decreases in tongue pressure may reduce the risk of aspiration.
