Answer

Indications for esophageal manometry and prolonged pH monitoring include the following:

  • Persistence of symptoms while taking adequate antisecretory therapy, such as PPI therapy

  • Recurrence of symptoms after discontinuation of acid-reducing medications

  • Investigation of atypical symptoms, such as chest pain or asthma, in patients without esophagitis

  • Confirmation of the diagnosis in preparation for antireflux surgery
