PurposeTransoral resection of Zenker’s diverticulum (TORD) was first reported in 2010. We present results for our modified approach to transoral resection (MTORD)—full-thickness cricopharyngeal myectomy, diverticulum sac excision, and suture closure of the pharyngotomy—and evaluate its safety and efficacy compared to endoscopic stapling and open approaches.MethodsA retrospective study was performed in patients who underwent transoral resection of Zenker’s diverticulum using MTORD, endoscopic stapler-assisted diverticulotomy (ESD), or trancervical diverticulectomy (TCD) from July 2009 to August 2017. Pre-operative evaluation included barium swallow and subjective characterization of swallowing dysfunction using the EAT-10 and Reflux Symptom Index (RSI). Complications, length of hospitalization, recurrence, and revision rates were also evaluated.ResultsOf 92 patients reviewed, 18 underwent MTORD, 45 underwent ESD and 29 underwent TCD. Major complications were only observed in ESD and TCD. Recurrence which required revision surgery was only observed in ESD. EAT-10 and RSI scores significantly improved and RSI scores normalized post-operatively for all approaches in short-term (< 1 year) follow-up.ConclusionsMTORD is a safe and effective option for complete Zenker’s diverticulectomy. Complication rates are low. To date, no patient has required reoperation, although more cases and longer term follow-up are needed for more complete comparison to ESD and traditional open excision.
