PS01.222: HAS A MEDIASTINOSCOPE-ASSISTED ESOPHAGECTOMY CONTRIBUTE TO CURABILITY AND MINIMAL INVASIVE SURGERY?

Abstract Background In a mediastinoscope-assisted esophagectomy, it is unknown whether it contributes to minimally invasive surgery or curability. We examined the outcome of treatment of a mediastinoscope-assisted esophagectomy performed in our hospital. Methods From June 2014 to October 2017, 31 patients underwent a mediastinoscope-assisted esophagectomy. The examined items were clinicopathological factors, preoperative complications, preoperative treatment, bleeding volume, operation time, postoperative complications, and recurrence. Results There were 29 males, 2 females, and the average age 66 years. As preoperative treatment, 12 nontreatment, 4 chemotherapies, and 15 chemoradiotherapy (CRT) were performed. Preoperative complications were found in 27 cases, among which 13 cases were respiratory complications. The percentage of double cancers was also high, 8 cases with synchronous cancer, and 6 cases with metachronous cancer. Gastric cancer accounted for half in synchronous cancer, and in metachronous lung cancer was 4 cases. The reconstructed organs were 29 cases of stomach tube and 2 cases of colon. The reconstruction route was 17 cases in front of the chest wall and the chest wall anterior route was selected for the case of preoperative CRT significantly. The average bleeding volume was 316 ml, and the average operation time was 560 minutes. Pathological tumor depth T0/1a/1b/2/3 were each 2/11/6/7/4 cases. In the postoperative complications, 12 cases of temporary recurrent nephropathy, 5 cases of anastomotic suture failure, 3 cases of pulmonary complications. There were 6 cases (19.3%) of recurrence. Postoperative recurrence was associated with significant pathological tumor depth. Conclusion A mediastinoscope-assisted esophagectomy decreased postoperative pulmonary complications and there were not many recurrences after surgery. It seemed to contribute to minimally invasive surgery and curability. Disclosure All authors have declared no conflicts of interest.

Video-assisted esophagectomy for esophageal cancer

Video-assisted surgery for esophageal cancer is an advanced surgical technique. It has been developed on the basis of the concept of minimally invasive surgery. Given that there are several options regarding the operative procedures for thoracic esophageal cancer, several laparoscopic approaches have been proposed. The first video-assisted thoracoscopic esophagectomy through a right thoracoscopic approach and the first transhiatal esophagectomy were reported in the early 1990s. A mediastinoscope-assisted esophagectomy has also been reported as a substitute for a blunt dissection of the esophagus. Moreover, a video-assisted Ivor-Lewis esophagectomy by right thoracotomy with intrathoracic anastomosis has also been performed. Furthermore, laparoscopic gastric mobilization and gastroplasty are also widely accepted substitutions for open laparotomy. This article reviews the literature on the laparoscopic approaches for esophageal cancer.
