Radical minimally invasive esophagectomy for esophageal cancer via transcervical and transhiatal approaches: a narrative review

OBJECTIVE: Minimally invasive esophagectomy (MIE) has been widely applied for the treatment of esophageal carcinoma. It is much less invasive, as it avoids employing a transthoracic procedure. BACKGROUND: MIE via transcervical and transhiatal approaches has been adopted in our center. In this approach, with the assistance of single-port techniques or robotic-assisted surgical systems, the esophagus is mobilized under visualization, which is followed by the removal of esophageal and mediastinal lymph nodes. METHODS: Increasing the surgical space by mediastinal insufflation or by elevation of the sternum with a hook may improve intraoperative identification of tissues and facilitate intraoperative mobilizations. The procedure can be performed simultaneously via both cervical and abdominal approaches without the need for intraoperative turning of the patient, which shortens the operative time. Also, there is no need for thoracotomy or single-lung ventilation, which avoids disturbance to the respiratory and circulation systems. CONCLUSIONS: Suitable instruments, especially state-of-the-art energy instruments, facilitate surgical separation and hemostasis. This surgical procedure has become increasingly sophisticated over the past decade, and its modular operation has been widely recognized. The feasible place of the neck-esophageal hiatus rendezvous is on the left main bronchus around the subcarinal region. Here we describe the technical features, key steps, and necessary precautions of this minimally invasive surgery for esophageal carcinoma.
