Abstract
Aim
To present a video of a complete bilateral recurrent laryngeal nerve lymphadenectomy performed during minimally invasive esophagectomy using thoracoscopic video-assisted surgery in the prone position.
Background and Methods
Surgical treatment for esophageal cancer needs detailed lymphadenectomy. Indeed, the number of surgically dissected lymph nodes is important for staging accuracy and also determines patient’s prognosis, including those along the recurrent laryngeal nerve. However, recurrent laryngeal nerve dissection remains difficult and increases the appearance of postoperative complications.
This is a video of a bilateral recurrent laryngeal nerve lymphadenectomy during thoracoscopic esophagectomy performed in the prone position in a female patient with esophageal cancer.
Results
A 75 year-old female was diagnosed with recurrent squamous cell middle third esophageal carcinoma. The patient had first been diagnosed eleven years ago, receiving chemoradiotherapy as a radical treatment. The patient achieved a complete response after treatment, which remained for eleven years. Eleven years later, during routine follow-up, tumor recurrence was identified in the middle third of the esophagus. After presentation in a Multidisciplinary Group the patient underwent minimally invasive McKeown esophagectomy.
First, a video-assisted thoracoscopic surgery was performed in the prone position to mobilize the thoracic esophagus and complete a detailed mediastinal lymph node dissection, including infra-carinal lymph nodes, bilateral bronchial lymph nodes and also bilateral recurrent laryngeal nerve lymph nodes.
Afterwards, the abdominal esophagus and lymph node dissection is performed using a laparoscopic approach, and also a left cervicotomy in the supine position. An assistance laparotomy was made to externalize the specimen and make the gastric conduit. A manual end-to end esophago-gastric anastomosis was executed and finally, a feeding jejunostomy tube was placed.
The patient presented a benign postoperative course, introducing enteral nutrition and oral intake developing no complications, such as dysphonia, nor dysphagia and was discharged on the 8th postoperative day. The postoperative barium swallow radiography showed no leaks nor other complications and pathology report confirmed tumor free resection margins.
Conclusion
Detailed mediastinal lymph node dissection and exhaustive bilateral recurrent laryngeal nerve lymphadenectomy can be safely performed by minimally invasive surgery, as is shown in the video. The technique shown is feasible, achieves a complete lymph-node dissection and avoids postoperative complications such as dysphonia and recurrent laryngeal nerve palsy.
Is there a role for intraoperative recurrent laryngeal nerve monitoring during high mediastinal lymph node dissection in three-stage oesophagectomy for oesophageal cancer?
