Minimally invasive techniques for oesophageal cancer surgery.

摘要

Innovative minimally invasive surgical (MIS) techniques have been explored for the purpose of oesophagectomy since the early 1990s, including various combinations of thoracoscopy, laparoscopy or laparoscopic-assisted methods, mediastinoscopy and open thoracotomy and laparotomy. The myriad of surgical approaches implies a lack of consensus on which is superior. Like open surgery, it is perhaps more important to have a tailored approach for the individual patient. MIS oesophagectomy has been shown to be feasible, and at least equivalent postoperative morbidity and mortality rates to open surgical resection have been demonstrated. Selected series have achieved less blood loss, reduction in some postoperative complications, decrease in intensive care and hospital stay, and better preservation of pulmonary function. Clear proof of superiority over conventional oesophagectomy methods however is not forthcoming since comparisons were often made with unmatched patient cohorts, and a well conducted randomized controlled trial has not been carried out. It is expected that with further improvements in instrumentation and experience, these difficult procedures may become more accessible and widely practised.
