Abstract:
Success of cricopharyngeal myotomy for specific and non-specific cervical dysphagia. Objective: The present study aimed to compare outcomes of cricopharyngeal myotomy (CPM) in patients with documented cricopharyngeal dysfunction (CPD) and those in whom the diagnosis is complex or in doubt. Materials and methods: Retrospective comparative study of all patients undergoing CPM between 2001 and 2010 at a single UK centre. Patients were classified as having either CPD (n = 15) or non-specific cervical dysphagia (NSCD) (n = 12) based on contrast swallow results. They completed a 10-point visual analogue scale (VAS) questionnaire regarding their ability to swallow solids preoperatively and 6 months postoperatively. Scores were compared between groups, and symptom recurrence at 12 months postoperatively was also noted. Results: The median VAS for all patients in both groups preoperatively was 5.5 and improved postoperatively to 8.0 (p<0.001), and median preoperative ratings between groups were similar (CPD = 6.0 vs. NSCD = 5.5; p>0.05). The CPD group scored better postoperatively compared to their NSCD counterparts (CPD = 9.0 vs. NSCD = 7.5; p<0.001). Recur- rence rate at 12 months was lower in CPD (12.5%) compared to NSCD (60%) patients. Conclusion: After CPM, patients with CPD showed significant improvement in swallowing solids, as did patients with NSCD, although to a lesser extent. CPD patients experienced better outcomes compared to their NSCD counterparts, including lower complication and recurrence rates. Larger studies are required before CPM can be advocated as the standard of care for NSCD patients.
