Transhiatal Chest Drainage Reduces The Frequency of Postoperative Thoracentesis In Transmediastinal Esophagectomy For Esophageal Cancer: A Retrospective Study
Abstract Background: Transmediastinal esophagectomy for esophageal cancer occasionally results in the postoperative accumulation of pleural effusion despite the preservation of the mediastinal pleura. Transhiatal chest drainage has reported utility in thoracic esophagectomy; however, its use in transmediastinal esophagectomy remains unelucidated. This study aimed to evaluate the effectiveness and safety of transhiatal chest drainage in transmediastinal esophagectomy.Methods: This retrospective study included patients who underwent transmediastinal esophagectomy for esophageal cancer from 2018 to 2020. The transhiatal chest drainage involved the insertion of a 19-Fr Blake® drain from the inferior hepatic space to the left thoracic cavity through the hiatus. The drainage group comprising 13 patients was compared with the non-drainage group comprising 13 patients in whom a transhiatal chest drainage tube was not placed during transmediastinal esophagectomy.Results: The frequency of thoracentesis in the drainage group was significantly lower than that in the non-drainage group (p = 0.03). There were no significant differences between the two groups in terms of the occurrence of other postoperative complications, duration of oxygen administration, and postoperative hospital stay.Conclusions: Transhiatal chest drainage could evacuate pleural effusion effectively and safely after transmediastinal esophagectomy. Therefore, this procedure is clinically useful in transmediastinal esophagectomy for esophageal cancer.
