Not Applicable
Conditions

Procedure: Thoraco-laparoscopic esophagectomy

Brief Summary

Esophageal cancer is one of the major diseases that seriously threatens an individual's health and life. To reduce the incidence of postoperative complications and mortality of esophageal cancer, thoraco-laparoscopic oesophagectomy (TLE) has been recommended by many guidelines since the 2000s. Additionally, with developments in endoscopy technology in recent years, mediastinoscopy-assisted transhiatal esophagectomy (MATHE) has been used in clinical practice. In 2015, the first mediastinoscopy combined with laparoscopic radical esophagectomy was reported systematically by Hitoshi Fujiwara. This surgical procedure has been performed in many centres in China. However, there is no multicentre prospective randomized controlled study that explored the safety, feasibility and short-term clinical efficacy between mediastinoscopy-assisted transhiatal esophagectomy and thoraco-laparoscopic esophagectomy. We aim to evaluate the feasibility and safety of MATHE.

Detailed Description

Esophageal resection remains the mainstay of treatment for esophageal cancer patients. Despite improvements in surgical technique and perioperative management, esophagectomy carries considerable operative risk. To reduce the incidence of postoperative complications and mortality of esophageal cancer, the optional of minimally invasive esophagectomy has been recommended by many guidelines since 2000s. In addition, with the development of endoscopy technology in recent years, mediastinoscopy-assisted transhiatal esophagectomy (MATHE) has been used in clinical practices. In 2015, the first mediastinoscopy combined with laparoscopic radical esophagectomy was reported systematically by Hitoshi Fujiwara. This surgical procedure has been performed in many centers of China since then. Compared with MIE, MATHE allows controlled dissection of upper mediastinum and biopsy of mediastinal lymph nodes. No study directly comparing MATHE versus MIE has been reported to date. In this report, we compare MATHE with MIE in terms of surgical feasibility, safety, and survival.We intend to adopt a randomized controlled study method. The study group is mediastinoscopy-assisted transhiatal esophagectomy (MATHE) group, and the control group is thoraco-laparoscopic esophagectomy (TLE) group. This study is expected to provide high-level evidence for the new methods and to provide better treatment options for patients with esophageal cancer.

Primary Outcome Measures

These respiratory complications involve respiratory distress or failure after the operation with continuation of mechanical ventilation, pulmonary atelectasis requiring sputum suction by bronchoscopy, pneumonia requiring specific antibiotics confirmed by thoracic X-ray or CT scan of the thorax and a positive sputum culture, and acute respiratory distress syndrome.
