Abstract

Background and study aims Oropharyngeal dysphagia (OPD) is prevalent in patients with Parkinson’s disease (PD). Upper esophageal sphincter (UES) dysfunction is an important pathophysiological factor for OPD in PD. The cricopharyngeus (CP) is the main component of UES. We assessed the preliminary efficacy of cricopharyngeal peroral endoscopic myotomy (C-POEM) as a treatment for dysphagia due to UES dysfunction in PD.

Patients and methods Consecutive dysphagic PD patients with UES dysfunction underwent C-POEM. Swallow metrics derived using high-resolution pharyngeal impedance manometry (HRPIM) including raised UES integrated relaxation pressure (IRP), raised hypopharyngeal intrabolus pressure (IBP), reduced UES opening caliber and relaxation time defined UES dysfunction. Sydney Swallow Questionnaire (SSQ) and Swallowing Quality of Life Questionnaire (SWAL-QOL) at before and 1 month after C-POEM measured symptomatic improvement in swallow function. HRPIM was repeated at 1-month follow-up.

Results C-POEM was performed without complications in all (n = 8) patients. At 1 month, there was an improvement in both the mean SSQ (from 621.5 to 341.8, mean difference –277.3, 95 %CI [–497.8, –56.7], P = 0.02) and SWAL-QOL (from 54.9 to 68.3, mean difference 9.1, 95 %CI [0.7, 17.5], P = 0.037) scores. Repeat HRPIM confirmed a decrease in both the mean UES IRP (13.7 mm Hg to 3.6 mm Hg, mean difference –10.1 mm Hg, 95 %CI [–16.3, –3.9], P = 0.007) and the mean hypopharyngeal IBP (23.5 mm Hg to 10.4 mm Hg, mean difference –11.3 mm Hg, 95 %CI [–17.2, –5.4], P = 0.003).

Conclusions In dysphagic PD patients with UES dysfunction, C-POEM is feasible and enhances UES relaxation and reduces sphincteric resistance to flow during the swallow, thereby improving dysphagia symptoms.
