Is minimally invasive esophagectomy indicated for cancer?

Esophagectomy is an important component in the comprehensive treatment of esophageal cancer. The 5-year survival in patients who are treated with esophagectomy is approximately 35% compared with approximately 16% for all patients. However, esophagectomy is a complex operation with high (40-60%) morbidity and 5-20% mortality rates reported by many centers. Minimally invasive approaches to esophagectomy have been developed over the past decade; potential advantages of minimally invasive esophagectomy (MIE) include a reduced risk of perioperative morbidity and mortality with equivalent oncologic outcomes, including extent of lymphadectomy and survival. However, significant debate still exists regarding the role of MIE in the treatment of esophageal cancer, particularly given the limitations in the widespread implementation of this technically challenging operation. This review summarizes the current status of the use of minimally invasive surgery in treating esophageal cancer and seeks to answer the question of whether MIE is indicated in the treatment of esophageal cancer.
