Final answer:
Manometry in this patient would likely reveal dysfunction of the lower esophageal sphincter (LES), consistent with gastroesophageal reflux disease (GERD).
Step-by-step explanation:
Manometry Findings in the Patient
In this patient, manometry would most likely reveal dysfunction of the lower esophageal sphincter (LES). The symptoms of heartburn and feeling a "sticking sensation" in the throat when swallowing liquids or solid foods are consistent with gastroesophageal reflux disease (GERD). In GERD, the LES, which normally prevents stomach acid from entering the esophagus, is dysfunctional, leading to acid reflux and its associated symptoms.
