Background
The adoption of minimally invasive esophagectomy has increased worldwide since its first description more than 15 years ago. The technique has evolved from a transhiatal to a minimally invasive approach of the thorax that allows a safe and radical mediastinal dissection. We present a case of a stenotic lesion of the midesophagus suspicious of malignancy that was completely resected through a MIS approach.

Patients and Method
A 46 years old inmate male was referred for an obstructive lesion of the mid esophagus due to chronic perforation reaction. Preoperative CT scan showed a lesion with intraluminal vegetations in the midesophagus; an Upper GI Endoscopy was performed with biopsy sampling that failed to show malignancy. A failed endoscopic dilation rised the suspicious of malignancy. The decision was made to perform a robotic assisted thoracoscopic total esophagectomy with a radical dissection of the mediastinum with an extended lymphadenectomy and gastric conduit reconstruction.

Results
In the OR, after oro-thracheal selective mono-bronchial intubation, a right robot-assisted thoracoscopic approach was achieved. The complete esophagus was dissected all around en-bloc with all Lymphatic tissue. Once thoracic part was completed an abdominal approach was perfomed to squeletonize the stomach and builds the gastric conduit. Finally through a cervicotomy, the reconstruction was performed in the neck. The main advantages of this procedure are the radicallity of the mediastinal en-bloc dissection preserving the benefits of the MIS approach.

Conclusions
In selected cases, a minimally invasive robotic approach may allow safe mediastinal en-bloc dissection and thorough thoracic lymph node dissection, respecting the oncological principles.
