PURPOSE: The most critical parameter in the evaluation of the effectiveness of minimally invasive esophagectomy for esophageal squamous cell carcinoma (SCC) is long-term outcome. In this study, patients in whom more than 5 years had elapsed since they had undergone minimally invasive esophagectomy for esophageal SCC were identified, and the 5-year overall survival (OS) rate and 5-year disease-free survival (DFS) rate were evaluated as the long-term outcomes.

METHODS: The stage, histology, perioperative complications, recurrence, and survival data were carefully reviewed in 49 patients who underwent minimally invasive esophagectomy for esophageal SCC between January 2008 and January 2010.

RESULTS: Postoperative 30-day complications were observed in 12 (24.5%) patients. There was no postoperative 30-day mortality. Recurrence was observed in 26 patients (53.1%): of these, 9 (18.4%) developed local recurrence and 14 (28.6%) distant metastasis. Three patients (6.1%) had both local and distant metastases. During the study period, there were 22 (44.9%) deaths, of which 20 were due to cancer and 2 were due to other causes. The patient 5-year OS and DFS rates were 58 and 45%, respectively.

CONCLUSION: Minimally invasive esophagectomy for the treatment of esophageal SCC is as feasible and safe as open esophagectomy in terms of both very long- and short-term outcomes.
