Abstract
Background
A meta-analysis of the current literature was performed to compare the perioperative outcome measures and oncological impact between minimally invasive and open esophagectomy.
Methods
Using the electronic databases Medline, Embase, Pubmed and the Cochrane Library, we performed a meta-analysis pooling the effects of outcomes of 1,008 patients enrolled into eight comparative studies, using classic and modern meta-analytic methods.
Results
Two comparisons were considered for this systematic review: (I) open thoracotomy vs. VATS/laparoscopy esophagectomy and (II) open thoracotomy vs. VATS esophagectomy. In comparison I: both procedures report equally comparable outcomes (removed lymph nodes, 30-day mortality, 3-year survival) with the exception of overall morbidity (P = 0.038; in favor of the MIE arm) and anastomotic stricture (P < 0.001; in favor of the open thoracotomy arm). In comparison II: No differences were noted between treatment arms concerning postoperative outcomes and survival.
Conclusions
In summary, both arms were comparable with regard to perioperative results and prognosis. Further prospective comparative or randomized-controlled trials focusing on the oncological impact of MIE are needed.
