[Oncologic esophageal resection and reconstruction : Open, hybrid, minimally invasive or robotic?]

Minimally invasive resections are increasingly employed in oncologic surgery for esophageal carcinoma. The new German S3 guideline states that esophagectomy, as well as reconstruction of the esophagus, can be performed minimally invasively or in combination with open techniques (hybrid). However, the current value of different techniques - ranging from complete minimally invasive esophagectomy over hybrid to robotic surgery - remains unregarded.This review provides a critical comparison of these techniques based on current evidence. Minimally invasive procedures of oncologic esophageal resection are safe in experienced hands and show numerous advantages with regard to postoperative reconvalescence. Laparoscopic gastrolysis with intra-abdominal lymphadenectomy and muscle sparing as well as anterolateral mini-thoracotomy (also via VATS as single-port technique) as a hybrid method also result in a relevant reduction of postoperative mortality and offer the possibility of extended mediastinal lymphadenectomy, which requires a high level of expertise when performed thoracoscopically. At present, robotic esophagectomy is applied in only a few clinics in Germany. A lack of evidence based on studies for esophageal surgery, as well as high acquisition and operating costs of the robotic system, have to be taken into account.
