ObjectiveEndoscopic Zenker's diverticulotomy (EZD) is typically performed via stapling (endoscopic staple diverticulotomy; ESD) or CO2 laser (endoscopic laser diverticulotomy; ELD). Conflicting reports exist on which approach provides optimal outcomes. This investigation compared objective fluoroscopic data between ESD and ELD.MethodsA retrospective review of all patients undergoing primary EZD at a tertiary center between January 1, 2014 and January 10, 2022 was performed. Patients undergoing ESD and ELD were matched by preoperative diverticulum size. Primary outcome measures were postoperative diverticulum size and change in diverticulum size from pre‐ to postoperative swallowing fluoroscopy. Secondary outcome measures were the Eating Assessment Tool (EAT‐10) score, penetration aspiration scale (PAS), pharyngeal constriction ratio (PCR), and pharyngoesophageal segment opening (PESo).ResultsThirteen matched pairs with complete fluoroscopic data were identified. The mean (±SD) age of the cohort was 74.0 (±8.5) years. There were no age or gender differences between groups (p > 0.05). The mean pre‐operative ZD size was 1.98 (±0.69) cm for ESD and 1.97 (±0.72) cm for ELD; the mean postoperative size was 0.84 (±0.62) cm for ESD and 0.34 (±0.27) cm for ELD (p < 0.05). Mean diverticulum size improved by 1.14 (±0.59) cm after ESD and 1.62 (±0.59) cm after ELD (p < 0.05). There were no significant differences in postoperative EAT‐10, PAS, PCR, or PESo between groups.ConclusionThe data suggest that endoscopic laser Zenker's diverticulotomy results in a greater improvement in diverticulum size than endoscopic staple diverticulotomy. The data did not suggest a difference in postoperative dysphagia symptom scores or other objective fluoroscopic parameters between staple and laser diverticulotomy.Level of EvidencesLevel 3 Laryngoscope, 2023

Objectives/Hypothesis: The Laryngopharyngeal Measure of Perceived Sensation (LUMP) is a recently validated patientreported outcome measure (PROM) aimed at evaluating the symptom severity of patients with globus pharyngeus (GP). The objective of this study was to define the normative values for the LUMP questionnaire.Study Design: Prospectively collected, descriptive research/scale development.Methods: The LUMP questionnaire was completed by 88 subjects. Individuals without throat-related symptoms such as dysphagia, dysphonia, or cough were provided LUMP. The results of the eight-item questionnaire were analyzed for standard error of the mean (SEM), mean, and standard deviation (SD).Results: Review of the 88 LUMP questionnaires elucidated a mean of 0.42 (SEM = 0.10, SD = 0.96) in the normative population. By gender, the female (n = 50) mean was 0.24, SD = 0.66, SEM = 0.09; for males (n = 38), the mean was 0.66, SD = 1.21, SEM = 0.20.Conclusions: This study provides normative data for the LUMP, a recently established PROM useful in patients with GP. A LUMP score greater than or equal to 3 should be considered abnormal and warrants additional attention.
