Minimally invasive pharyngo-laryngo-esophagectomy: a salvage procedure for recurrent postcricoid esophageal cancer

Abstract

Hypopharyngeal and cervical esophageal tumors represent 5-10% of all esophageal neoplasms and are challenging for both surgeons and oncologists, because the choice of the adequate therapeutic strategy is not clearly defined and therefore difficult. In fact, although surgical treatment represents the gold standard of therapy, chemo-radiotherapy, previously used as adjuvant treatment, has been more recently adopted with curative intent, leaving to surgery a salvage role only. When surgery is required it is advisable to reduce patients' trauma. The present study reports on a personal technique for minimally invasive pharyngo-laryngo-esophagectomy and reconstruction with the whole stomach. We use a laparoscopic approach for mobilization of the stomach, transhiatal esophageal dissection and to follow transhiatal gastric transposition to the neck combined to a cervicotomy to perform pharyngo-laryngectomy, proximal esophageal mobilization, and pharyngo-gastric anastomosis. We performed this technique on four patients with recurrent disease after initially curative primary chemo-radiotherapy. Mean operative time was 345 min (range: 300-384). There were no intraoperative complications. All patients were extubated immediately after the operation and were managed in postoperative care unit for a mean time of 10 days (range: 7-12). Enteral nutrition was begun on post-operative day (POD) 1. The nasogastric tube and drainages were removed on POD 11, and patients immediately started oral nutrition. One patient had a TIA (transient ischemic attack) on POD 2. All patients were discharged within 20 days (18-20). Initial experience with this minimally invasive technique in selected patients is encouraging because it seems to minimize postoperative complications and allows early rehabilitation.
