A cooperative approach for treatment of Zenker's diverticulum.

BACKGROUND: Symptomatic Zenker's diverticulum management has evolved from an open intervention to an endoscopic management. At our center, both an otolaryngologist and a gastroenterologist are present in the operating room when treating these lesions. An intra-procedural consensus is reached to undergo either rigid endoscopy or flexible endoscopic diverticulotomy with ENT guidance. We evaluated the real-world efficacy with a cooperative gastroenterology-otolaryngology approach. METHODS: Single-center retrospective study of patients who underwent a cooperative endoscopic diverticulotomy by a gastroenterologist and otolaryngologist at Cleveland Clinic Florida between 2012 and 2019. Demographic and clinical data, intra-procedural findings/complications, post-procedural symptoms, recurrence rate, and reintervention variables were extracted. Patients included in the study were > 17 years old, with symptomatic confirmed typical single Zenker's diverticulum. RESULTS: 63 subjects were identified. Patients were predominantly males (63.5%) and white (84.1%), with mean age 73.5 years (53-95). Most subjects presented dysphagia (98.4%), mostly to solids (79.4%). Other demographic and clinical data are described in Table 1. The diverticula had a mean size of 36.3 mm. In 30.1% of the cases food debris was found during the procedure. The mean procedure length was 38.4 minutes. All cases were performed as outpatient. Technical success was achieved in all cases. Patients were followed for a mean of 3.24 months post-procedure. Clinical success was achieved in 92% subjects. One intra-procedural perforation was treated with endoclip. Table 1 Pre-procedural demographic and clinical variables in patients undergoing Zenker's diverticulum cooperative approach Variable Value (n = 63) Sex, n (%)  Male  Female 40 (63.5) 23 (36.5) Ethnicity/Race, n (%)  Non-Hispanic White  Hispanic  Black 53 (84.1) 7 (11.1) 3 (4.8) Smoking status, n (%)  Never  Former  Active 29 (46.0) 26 (41.3) 8 (10.7) Previous intervention for Zenker's diverticulum, n (%) 12 (19.1) Dysphagia, n (%)  Only to solids  Only to liquids  Both solids and liquids 50 (79.4) 0 (0) 12 (19.0) Regurgitation of food, n (%)  Chronic cough, n (%) 13 (20.6)  Halitosis, n (%) 9 (14.3) CONCLUSION: A cooperative endoscopic approach by gastroenterology and otolaryngology for symptomatic Zenker's diverticulum management offered excellent technical and clinical success. This approach proved to be safe and effective.

Case 223: Arytenoid Dislocation.

A 71-year-old man with a history of atrial fibrillation refractory to medical therapy and lung cancer status after left upper lobectomy presented to our hospital for elective cardioversion and rate control with tikosyn. Overnight, the patient became unresponsive and was found to be in a state of cardiogenic shock. A code was called, and he was stabilized after cardioversion and bedside intubation. His stay in the intensive care unit was complicated by ventilator-associated pneumonia. The patient subsequently underwent multiple failed extubation attempts, requiring two additional reintubations. He was finally extubated 18 days after his initial admission to the intensive care unit. After he was discharged, he reported a hoarse voice and was only able to whisper. His voice varied in timbre and volume, and it became hoarser with use. Otolaryngology evaluation, including laryngoscopy and video stroboscopy, showed immobility of the right vocal cord. He was referred for speech therapy, and a computed tomographic (CT) examination of the neck was ordered.
