Robot-assisted minimally invasive esophagectomy is equivalent to thoracoscopic minimally invasive esophagectomy

摘要

The use of the surgical robot has been increasing in thoracic surgery. Its three-dimensional view and instruments with surgical wrists may provide advantages over traditional thoracoscopic techniques. Our initial experience with thoracoscopic robot-assisted minimally invasive esophagectomy (RAMIE) for esophageal cancer was compared with our traditional thoracoscopic minimally invasive esophagectomy (MIE) approach for esophageal cancer. A retrospective review of a prospective database was performed. From July 2008 to October 2009, 43 patients underwent MIE resection. Patients who had benign disease and intrathoracic anastomosis were excluded. Results are presented as mean ± SD. Significance was set as P < 0.05. Eleven patients who underwent RAMIE and 26 who underwent MIE were included in the cohort. No differences in age, sex, race, body mass index, or preoperative radiotherapy or chemotherapy between the groups were observed. No significant differences in operative time, blood loss, number of resected lymph nodes, postoperative complications, days of mechanical ventilation, length of intensive care unit stay, or length of hospital stay were also observed. In this short-term study, RAMIE was found to be equivalent to thoracoscopic MIE and did not offer clear advantages.
