Abstract

Objectives: We directly compared endoscopic carbon dioxide (CO2) laser and stapler treatment methods for both cricopharyngeal hypertrophy (CPH) and Zenker's diverticulum (ZD). Methods: We performed a single-institution retrospective chart review of 153 patients who underwent either CO2 laser- assisted or stapler-assisted endoscopic cricopharyngeal myotomy (CPM). Results: Isolated CPH was more likely to be treated with the CO2 laser than by stapler techniques. The ZD pouch size decreased significantly after surgery in both laser (p = 0.04) and stapler (p = 0.008) groups. The average duration of the procedure for CPM was longer for the laser than for the stapler (p = 0.01). Both techniques were successful when used in revision procedures. The overall complication rates were not statistically significantly different. Laser surgery trended toward a higher rate of major complications (2.4% versus 0%). Symptomatic recurrence was more likely after stapler surgery (p = 0.002). The rates of revision surgery were similar in the two groups (3.3% for laser and 4.3% for stapler). Conclusions: In the treatment of isolated CPH or ZD, stapler-assisted endoscopic surgery results in a shorter operative time, whereas laser-assisted CPM results in a decreased incidence of symptomatic recurrence.
