Safe and efficient 2-step implementation of totally minimally invasive esophagectomy.

Background: The clinical benefits of totally minimal invasive esophagectomy (TIME) compared to open esophagectomy are documented and include reduced morbidity like pulmonary infections, shorter hospital stay and an increase in short-term quality of life. However, transition to TIME can be associated with a learning curve associated increased morbidity. We report our implementation of TIME using a 2-step approach, where the thoracoscopic part was added to the laparoscopic part in carefully selected patients. The hypothesis was that the 2-step implementation provides a safe and efficient implementation without compromising the outcomes for the patients. The aim of this study was to evaluation the implementation of minimal invasive esophagectomy at Aarhus University Hospital, where a 2-step implementation strategy has been used. Methods: In this retrospective observational cohort study a total of 369 patients with esophagus or gastroesophageal cancers underwent esophagectomy from September 1 Results: Anastomotic leakage occurred in 7.5% of the cases and pneumonia occurred in 5.8% of the cases. The lymph node count reached 16 or more in 94.3% of the cases and R0-resection was performed in 98.3% of the cases. Textbook outcome for esophageal cancer surgery was achieved in 45.8% of the patients. Conclusions: Hybrid minimal invasive esophagectomy can serve as a step towards totally minimally invasive esophagectomy. In our institution, major learning curve associated complications was avoided and a high level of cancer control was achieved by a 2-step implementation strategy in carefully selected patients.
