A control group with dysphagia due to radiographically confirmed esophageal dysmotility, prominent cricopharyngeal bar, or stricture was identified.

Twelve (52.17%) of the remaining 23 Zenker diverticulum patients and 2 of the 73 (2.74%) control patients had greater pooling in the left versus right piriform sinus (2\u2010tailed <jats:italic>t<\/jats:italic> test, <jats:italic>P<\/jats:italic> &lt;. 0001). The sensitivity of this physical examination finding in identifying patients with Zenker diverticulum was 52.17% (95% confidence interval, 31.08%\u201072.58%) and specificity was 97.26% (95% confidence interval, 89.56\u201099.52%). Patients with Zenker diverticulum less than 4\u00a0cm in size had increased pooling in the left versus right piriform compared with larger diverticulums. After surgical intervention, there was a statistically significant decrease in the asymmetrical pooling (2\u2010tailed <jats:italic>t<\/jats:italic> test, <jats:italic>P<\/jats:italic> =. 0067).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Increased pooling in the left compared with the right piriform, on in\u2010office endoscopy, is predictive of the presence of a Zenker diverticulum. This information can sharpen clinical acumen in evaluating patients with dysphagia.
