Sato S, Nakatani E, Higashizono K, et al. - Via this study, researchers sought to ascertain the predictive value of various factors related to the size of the thoracic inlet for anastomotic leak after esophagectomy. Among 248 assessed patients who underwent esophagectomy with retrosternal reconstruction of the gastric conduit between January 2013 and March 2019, occurrence of anastomotic leak was reported in 38 patients (15.3%). Findings revealed correlation of the ratio of the sternum-trachea distance/sternum-vertebral body distance with cervical anastomotic leak after retrosternal gastric conduit reconstruction after esophagectomy. Consideration to measurement of the thoracic inlet space may be given in preoperative planning, such as for the route of the conduit for reconstruction and anastomotic site. .
