Larynx-preserving hybrid surgery with endoscopic laryngopharyngeal surgery and open surgery for cervical esophageal cancer invading pharynx.

Abstract

Larynx preserving hybrid surgery with endoscopic laryngopharyngeal surgery and open surgery (HELPS) was created for resectable cervical esophageal cancer (CEC) invading the hypopharynx. This study aimed to verify the effectiveness and to evaluate the feasibility of the new HELPS treatment method. Between 2014 and 2018, 19 patients with CEC invading the hypopharynx were treated with HELPS. The postoperative complications and survival rates were reviewed. Postoperative recurrent laryngeal nerve paralysis occurred in four patients. All patients consumed food orally without a feeding tube at the time of the discharge. The median follow-up period was 27months. The 2- and 3-year overall survival rates were 94.7 and 71.5%, respectively. HELPS, a new surgical treatment method that utilizes endoscopic surgery, is effective, feasible and beneficial for preserving the larynx in patients with CEC even if the tumor invaded the pharynx.
