[Evidence in minimally invasive oncological surgery of the esophagus].

Background: Thoracoabdominal esophagectomy still plays a major role in the oncological treatment for esophageal cancer. Minimally invasive procedures were developed to reduce the high rate of postoperative morbidity and mortality without negatively affecting the oncological outcome.
Objective: What evidence supports minimally invasive oncological surgery of the esophagus? Do patients benefit from minimally invasive esophagectomy compared to an open approach? Is the reduction of surgical access trauma specifically advantageous?
Material and Methods: Review, evaluation and critical analysis of the international literature.
Results: A reduction in postoperative morbidity by decreasing surgical trauma was confirmed by three prospective randomized clinical trials, while showing at least similar oncological outcomes. Diverse retrospective analyses and meta-analyses also came to the same result.
Conclusion: A minimization of surgical access trauma during thoracoabdominal esophagectomy reduces postoperative morbidity compared to conventional open surgery. Recent evidence suggests that oncological outcomes are not altered depending on the surgical approach.
