Abstract
Elevated relaxation pressure in combination with intact or weak peristalsis characterizes esophagogastric junction (EGJ) outflow obstruction. Symptoms of EGJ outflow obstruction include dysphagia and atypical chest pain. EGJ outflow obstruction can be diagnosed using high-resolution manometry (HRM), but there is a lack of consensus regarding treatment. We present a case report of a 43-year-old man with a history of headache and mitral valve disorder who suffered from intermittent atypical chest pain for 20 years. A diagnosis of EGJ outflow obstruction was made using esophageal HRM. Due to medication intolerance, robotic-assisted esophageal myotomy and Belsey-Mark IV fundoplication were performed. The symptoms went into complete remission and no motility disorders were detected on postoperative HRM. HRM is a useful diagnostic examination for EGJ outflow obstruction. The robotic systems-assisted long segment myotomy may potentially play an important role in the treatment of EGJ outflow obstruction-related functional chest pain.
