This study aims to evaluate the upper esophageal sphincter (UES) motility in patients with gastroesophageal reflux disease (GERD) as compared to healthy volunteers. We retrospectively studied the HRM tests of 44 patients (median age: 61 years, 54% females) under evaluation for GERD. The manometric UES parameters of these patients were compared to 40 healthy volunteers (median age: 27 years, 50% females). Almost half of the patients had a short and hypotonic UES. Patients with extraesophageal symptoms had a higher proportion of hypotonic UES as compared to patients with esophageal symptoms. Reflux pattern did not influence manometric parameters. Proximal reflux (any number of episodes) was present in 37(84%) patients (median number of proximal episodes = 6). Manometric parameters are similar in the presence or absence of proximal reflux. There is not a correlation between the UES length and UES basal pressure. In conclusion, our results show that: (1) the manometric profile of the UES in patients with GERD is characterized by a short and hypotonic UES in half of the patients; (2) this profile is more pronounced in patients with extraesophageal symptoms; and (3) neither the presence of proximal reflux nor reflux pattern bring a different manometric profile.

Background Epiphrenic diverticulum (ED) is a pulsion pseudodiverticulum found in the distal 10 cm of the esophagus. Motility disorders are present in the majority of patients with ED explaining the pathophysiology of this rare disease. Achalasia is the most common underlying disorder. We present a review on the diagnosis and management of ED in the setting of achalasia. Methods Literature review. Results Symptoms are most related to the underlying motility disorder. The diagnostic workup should always include an upper digestive endoscopy and a barium esophagogram. Esophageal manometry identifies the motility disorder in most patients. Therapeutic options include laparoscopic, thoracoscopic and endoscopic procedures. While a myotomy must always be performed, diverticulectomy is not always necessary. Conclusions Epiphrenic diverticulum is a rare condition whose pathophysiology involves an underlying motility disorder-achalasia in most cases. Symptoms usually include dysphagia, regurgitation, heartburn, and respiratory complaints and correlate with the motility disorder rather than the diverticulum per se. Upper digestive endoscopy and barium esophagogram are needed for the diagnosis-manometry may add useful information but is not imperative for the treatment. Laparoscopic Heller myotomy with a partial fundoplication is the procedure of choice, with satisfactory symptom relief and several advantages over the thoracic approach. Diverticulectomy may be performed in selected patients. Peroral endoscopic myotomy (POEM) are novel techniques, effective and minimally invasive that can be an option for patients unfit for surgery.
