Minimally invasive esophagectomy: a teaching hospital's first year experience

Surgical resection of the esophagus remains the mainstay of treatment for esophageal cancer. However, esophagectomy is associated with significant morbidity and mortality in the postoperative period. We have recently altered our practice pattern to include minimally invasive esophagectomy (MIE) as the approach of choice in the hope of minimizing morbidity associated with this procedure. In this retrospective analysis, we compare outcomes of our first year performing MIE to the previous 3 years of open esophagectomy (OE) at a single teaching hospital. Sixty-five patients underwent esophagectomy between June 2002 and July 2006. Among these, 22 patients underwent MIE between June 2005 and July 2006 and 43 patients underwent OE. The two groups were comparable with regards to age, comorbidities and pathologic stage. The MIE group had less operative blood loss (178 mL vs. 356 mL), decreased respiratory complications requiring mechanical ventila-tion (5% vs. 23%), increased number of lymph nodes procured per procedure (15 vs. 8), and increased number of patients discharged within 10 days (72% vs. 28%) when compared to the OE group. No difference was identified in mortality, complications, or length of stay.
