Transoral robotic surgery hypopharyngectomy (TORSH): feasibility and outcomes.

PURPOSE

With the development of minimal invasive procedure, trans-oral robotic surgery (TORS) is expanding in the field of ENT. Most reviews focus on oropharyngeal and laryngeal (supra-glottic) localization. We report here the feasibility and outcomes of TORS hypopharyngectomy (TORSH) for selected patients with hypopharyngeal tumor.

METHODS

Between September 2009 and July 2017, 22 patients, retrospectively included, underwent TORSH with curative intent.

RESULTS

From 22 successful hypopharyngectomy, no conversion to open procedure was needed. Three patients (13%) presented a post-operative bleeding and were managed by surgical revision. No fistula was encountered. The 3-year overall survival and disease-specific survival rates were 54 and 92%, respectively. Patients started oral feeding after an average of 7 days. Naso-gastric feeding tubes were removed after a median period of 16 days. Two patients (9%) needed a transient gastrostomy (< 1 year). Three patients (13%) received a transient tracheostomy (< 2 months). Median hospitalization stay was 13 days.

CONCLUSIONS

TORSH is a safe technique. Patients' outcomes are favorable and the post-operative morbidity is reduced compared to open neck approach. Hospitalization length and safe swallowing time are reduced.
