Transhiatal chest drainage in mediastinoscope and laparoscope-assisted esophagectomy for esophageal cancer: a retrospective study

Abstract

BackgroundMediastinoscope and laparoscope-assisted esophagectomy for esophageal cancer occasionally causes postoperative accumulation of pleural effusion despite the preservation of the mediastinal pleura. Transhiatal chest drainage has been reported to be useful for thoracic esophagectomy; however, its use in mediastinoscope and laparoscope-assisted esophagectomy remains unelucidated. This study aimed to evaluate the effectiveness and safety of transhiatal chest drainage in mediastinoscope and laparoscope-assisted esophagectomy.MethodsThis retrospective study included patients who underwent mediastinoscope and laparoscope-assisted esophagectomy for esophageal cancer from 2018 to 2021. Transhiatal chest drainage involved the insertion of a 19-Fr Blake® drain from the abdomen to the left thoracic cavity through the hiatus. We assessed its effectiveness and safety by the daily drainage output, accumulation of postoperative pleural effusion, frequency of postoperative thoracentesis, and other complications. The drainage group comprising 24 patients was compared with the non-drainage group comprising 13 patients, in whom a transhiatal chest drainage tube was not placed during mediastinoscope and laparoscope-assisted esophagectomy.ResultsThe median daily output of the transhiatal chest drainage was 230 mL on day 1, 385 mL on day 2, and 313 mL on day 3. The number of patients with postoperative pleural effusion was significantly reduced from 10/13 (76.9%) in the non-drainage group to 4/24 (16.7%) in the drainage group (p = 0.001). The frequency of thoracentesis in the drainage group was significantly lower than that in the non-drainage group (p = 0.002). There were no significant differences in the occurrence of other postoperative complications.ConclusionsTranshiatal chest drainage could evacuate pleural effusion effectively and safely after mediastinoscope and laparoscope-assisted esophagectomy.
