Minimally invasive esophagectomy performed with the patient in a prone position: a systematic review

Abstract

Purpose

We reviewed the surgical results of minimally invasive esophagectomy for esophageal cancer, performed with the patient in a prone position (MIE-PP), to assess its benefits.

Methods

A systematic literature search was performed, and articles that fully described the surgical results of MIE-PP were selected. Parameters such as operative time, blood loss, and postoperative outcomes were compared with those obtained for open transthoracic esophagectomy (OE) and minimally invasive esophagectomy in a lateral decubitus position (MIE-LP).

Results

The conversion rate from MIE-PP to open surgery was very low. MIE-PP was associated with longer operative time and lower blood loss than OE. Although studies from a single institution did not show an apparent difference in morbidity or mortality among the three operative groups, results of a multicenter randomized controlled trial showed a reduction in pulmonary infection and recurrent laryngeal nerve palsy in MIE-PP, compared with OE. The benefits of MIE-PP vs. those of MIE-LP remain controversial.

Conclusion

Theoretically, the operative results of MIE-PP might be better than those of MIE-LP for patients with esophageal cancer; however, studies have not yet verified this. Further clinical studies are required to establish whether the advantages of MIE-PP can be translated into clinical outcome.
