Cricopharyngeal Myotomy in National Surgical Quality Improvement Program (NSQIP): Complications for Otolaryngologists Versus Non-otolaryngologists.

Objective: Comparing outcomes after cricopharyngeal myotomy (CM) performed by otolaryngologists (OTO) and non-otolaryngologists (NO).

Methods: A retrospective analysis of the 2014-19 ACS-NSQIP database (American College of Surgeons National Surgical Quality Improvement Program) of patients who underwent open CM (CPT code 43030) as their primary procedure. Analyzed variables include medical comorbidities, operative time, the total length of stay, readmission, reoperation, concurrent procedures, postoperative complications, and postoperative diagnoses. 183 patients were included, 97 (53%) females and 86 (47%) males. 120 had surgery by OTO and 63 by NO.  Results: There were no differences in preoperative morbidity. OTO had more outpatient surgeries compared to NO (p<.001). OTO had a longer mean operating time (p=.008). OTO had a higher proportion of concurrent laryngeal procedures and other unspecified procedures compared to NO, while NO had a higher proportion of concurrent esophageal procedures (p=.028). The total length of stay was not significantly different between the two groups. 5.8% OTO and 7.9% NO patients were readmitted for a related reason (p=.586). Complications were similar between the two groups (p>.05). NO had more postop diagnoses of acquired diverticula and achalasia of the stomach cardia, while OTO had more diagnoses of dysphagia and muscular dystrophy (p<.001).  Conclusion: There were differences in the surgical setting, length of procedure, concurrent procedures, and postop diagnoses between NO and OTO surgeons but similar complication rates.
