OBJECTIVE: To analyze the causes of the esophagogastric junction outlet obstruction (EGJOO) patients, to discuss the differences of the clinical manifestation and esophageal motility characteristics between the anatomic EGJOO (A-EGJOO) and functional EGJOO (F-EGJOO) subgroups, and to search the diagnostic values of the specific metrics for differentiating the subgroups of EGJOO patients. METHODS: For the current retrospective study, all the patients who underwent the esophageal high resonance manometry test were retrospectively analyzed from Jan 2012 to Oct 2018 in Peking University Third Hospital. The EGJOO patients were enrolled in the following research. The clinical characteristics, such as symptoms and causes of the patients were studied. Then the patients were divided into two subgroups as A-EGJOO subgroup and F-EGJOO subgroup. The clinical symptoms and the main manometry metrics were compared between these two subgroups. The significant different metrics between the two groups were selected to draw receiver operating characteristic (ROC) curves and the diagnostic values were analyzed in differentiating the A-EGJOO and F-EGJOO subgroups. RESULTS: The most common symptom of EGJOO was chest pain or chest discomfort (30.63%), then the dysphagia (29.73%), and acid regurgitation/heartburn (27.03%). Non-erosive reflux disease (36.04%) was the most popular cause for EGJOO, then the reflux esophagitis (17.12%). Besides the intra-EGJOO and extra-EGJOO lesions, the connective tissue disease (6.31%) and central nervous diseases (2.70%) were found to be the etiology of EGJOO. The causes of the rest 19 EGJOO were unknown. A-EGJOO patients presented significantly higher intra bolus pressure (IBP) than that of F-EGJOO [6.80 (5.20, 9.20) mmHg vs. 5.10 (3.10, 7.60) mmHg, P=0.016]. The area under curve of IBP was 0.637. When IBP≥5.15 mmHg, the sensitivity was 78.60% and specificity 50.70% to differentiate A- or F-EGJOO. CONCLUSION Chest pain or chest discomfort was the most common symptom in EGJOO patients. Besides the intraluminal structural disorders, the extra-luminal causes were found in EGJOO patients. A-EGJOO presented higher IBP than that of F-EGJOO patients. The cutoff value of IBP to differentiate A-EGJOO from EGJOO was 5.15 mmHg with sensitivity 78.06% and specificity 50.70%. However for the low area under curve, the diagnostic value of IBP was limited.

Achalasia is a motility disorder of the esophagus that is characterized by loss of ganglionic neurons within the myenteric plexus of the lower esophageal sphincter (LES) resulting in failure of the LES to relax. Clinically this disorder presents with simultaneous dysphagia to solids and liquids, and if left untreated, leads to esophageal dilation, which can give rise to many adverse consequences. Extrinsic compression of respiratory structures is one such consequence, and rarely, cases of tracheal compression secondary to achalasia have been reported. However, cases of extrinsic bronchial compression are yet rarer. Here, we present a case series comprised of two patients with achalasia who presented with extrinsic bronchial compression by a dilated esophagus secondary to achalasia.

With the advances in technology and medical knowledge, new diseases are being identified and investigated. Esophageal motility disorders have been re-defined using high-resolution manometry and their pathogenesis are being better understood. The use of opioid analgesics is increasing worldwide, particularly in the United States, but their chronic use can cause opioid-induced esophageal dysfunction, which mimics spastic motor disorders, including achalasia type 3 or 2 and esophagogastric junction outflow obstruction. Eosinophilic esophagitis is identified by eosinophilic infiltration confirmed on a pathological examination. The condition is often associated with esophageal motility abnormalities. On the other hand, recent studies have suggested that muscle-predominant eosinophilic infiltration, eosinophilic esophageal myositis, might manifest as spastic motor disorders, including achalasia or jackhammer esophagus. Lymphocytic esophagitis is an unusual esophageal condition, which is confirmed by the increased number of lymphocytes in the esophageal epithelium. Although several reports have supported the existence of lymphocytic esophagitis, it is still unclear whether lymphocytic esophagitis is a distinct disease entity or another spectrum of other esophageal diseases, such as gastroesophageal reflux disease or eosinophilic esophagitis. This review presents evidence and reports on the emerging issues in esophageal motility disorders, including opioid-induced esophageal dysfunction, eosinophilic esophagitis with eosinophilic esophageal myositis, and lymphocytic esophagitis.

BACKGROUND/AIMS: Timed barium esophagram (TBE) is used the classification of esophageal motility disorders and assessing esophageal function. Currently, there are no published studies examining the relationship between high-resolution manometry and TBE in patients with esophagogastric junction outflow obstruction (EGJOO). This study seeks to evaluate this relationship and identify manometric variables that may indicate further evaluation using TBE. METHODS: Retrospective review of medical records identified patients with a diagnosis of EGJOO per the Chicago classification version 3.0. TBE was performed using standard protocol. Patients were divided into 2 groups based on complete emptying or persistence of standing barium column at 5 minutes. RESULTS: Eleven patients were identified with EGJOO who underwent both high-resolution manometry and TBE within 3 months. Five patients had no standing barium column at 5 minutes, while 6 patients had a persistent barium column. Mean age of each group was 54.0 years and 57.8 years, respectively. Patients with abnormal TBE were found to have significantly elevated intrabolus pressure (IBP) compared with patients who had a normal TBE. CONCLUSIONS: In our study, we found significant differences in IBP between these patient groups. These findings suggest that patients with EGJOO and elevated IBP may prompt further clinical evaluation with TBE in order to clarify clinical diagnosis and guide therapeutic intervention.

Gastroesophageal reflux disease (GERD) is a very common disease, and the prevalence in the general population has recently increased. GERD is a chronic relapsing disease associated with motility disorders of the upper gastrointestinal tract. Several factors are implicated in GERD, including hypotensive lower esophageal sphincter, frequent transient lower esophageal sphincter relaxation, esophageal hypersensitivity, reduced resistance of the esophageal mucosa against the refluxed contents, ineffective esophageal motility, abnormal bolus transport, deficits initiating secondary peristalsis, abnormal response to multiple rapid swallowing, and hiatal hernia. One or more of these mechanisms result in the reflux of stomach contents into the esophagus, delayed clearance of the refluxate, and the development of symptoms and/or complications. New techniques, such as 24-hour pH and multichannel intraluminal impedance monitoring, multichannel intraluminal impedance and esophageal manometry, high-resolution manometry, 3-dimensional high-resolution manometry, enoscopic functional luminal imaging probe, and 24-hour dynamic esophageal manometry, provide more information on esophageal motility and have clarified the pathophysiology of GERD. Proton pump inhibitors remain the preferred pharmaceutical option to treat GERD. The ideal target of GERD treatment is to restore esophageal motility and reconstruct the anti-reflux mechanism. This review focuses on current advances in esophageal motor dysfunction in patients with GERD and the influence of these developments on GERD treatment.

Current parameters of the Chicago classification include assessment of the esophageal body (contraction vigour and peristalsis), lower esophageal sphincter relaxation pressure, and intra-bolus pressure pattern. Esophageal disorders include achalasia, esophagogastric junction outflow obstruction, major disorders of peristalsis, and minor disorders of peristalsis. Sub-classification of achalasia in types I, II, and III seems to be useful to predict outcomes and choose the optimal treatment approach. The real clinical significance of other new parameters and disorders is still under investigation.

Laryngopharyngeal reflux disease (LPRD) is common in laryngologic practice. In Korea, up to 1 out of every 5 patients who visit otorhinolaryngology clinic is supposed to have LPRD with symptoms and physical findings. Major symptoms of LPRD include hoarseness, cough, reflux symptom and mild dysphagia. Even though LPRD is common, its diagnosis may be difficult, because its symptoms are nonspecific and the laryngeal findings are not always associated with symptom severity. In Recent study, 66.4% of Patient who has LPRD also associated with esophageal motility disorders. Esophageal achalasia is a disease of unknown etiology characterized by an absence of peristalsis in the body of esophagus and nonrelaxing hypertension of the lower esophageal sphincter. Common cause is loss of ganglion cells in Auerbachs plexus. The classic triad of symptoms in achalasia includes dysphagia, regurgitation and weight loss. LPRD and esophageal achalasia have similar symptoms but have different treatment of choice. The Differentiation diagnosis of theses disease is important and should be established by history, radiologic examination and endoscopic examination. We recently assessed a 59-year-old female patient who complained of an epigastric pain, dysphagia and chronic cough. LPRD was initially diagnosed on Laryngoscopic examination and Reflux Symptom Index, but patient was not relieved of any symptoms after treatment of Proton Pump Inhibitor for 3 months. After high resolution manometry, esophageal achalasia was finally diagnosed. We report this case regarding the diagnosis and treatment with review of literatures because we have to think about esophageal motility disorders as a differential diagnosis in laryngology.

BACKGROUND AND OBJECTIVES: Globus pharyngeus is a sensation of foreign body in the throat. There are many studies evaluate relationships between globus pharyngeus and organic diseases such as laryngopharyngeal reflux, esophageal motility disorders as well as psychotic causes. But, Also many patients without etiologic causes complain of globus sensation. The authors performed a study that evaluate association between oral water intake and symptoms of globus sensation on the basis of a belief that pharyngeal dehydration due to lack of oral water intake causes globus sensation. MATERIALS AND METHODS: A survey using visual analogue scale to evaluate symptoms was performed with 73 patients with globus pharyngeus. RESULTS: Patients who drink water less than 500 mL per day (p=0.04) and less than five times per day (p=0.02) were improved after 6 months due to education and doctor's recommendation. CONCLUSION: Frequent and enough water intake should be recommended to resolve symptoms of globus sensation.

BACKGROUND/AIMS: Little data exists about esophageal body dysmotility and reflux patterns in refractory gastroesophageal reflux disease (RGERD) patients off therapy. We aimed to evaluate effects of esophageal body dysmotility on reflux parameters in RGERD patients by combining impedance-pH monitoring and high-resolution manometry (HRM). METHODS: We retrospectively reviewed the impedance-pH data and HRM metrics in patients with refractory gastroesophageal reflux symptoms. Impedance-pH monitoring and manometric data were compared between 2 groups: ineffective esophageal motility (IEM) and normal motility. RESULTS: Forty-eight patients (30 males, mean age 54.5 years) were included (16 erosive esophagitis, 24 non-erosive reflux disease, and 8 functional heartburn), amongst which 24 subjects showed IEM, and others had normal motility. Number of patients who had a large break in the IEM group was significantly higher than that of normal motility patients. IEM group had more patients with weakly acid reflux and long term acid reflux than the normal group (P = 0.008, P = 0.004, respectively). There was no statistical difference in baseine impedance levels from z4 to z6 between the 2 groups (2911 ± 1160 Ω vs 3604 ± 1232 Ω, 2766 ± 1254 Ω vs 3752 ± 1439 Ω, 2349 ± 1131 Ω vs 3038 ± 1254 Ω, all P > 0.05). Acid exposure time, numbers of long term acid reflux and weakly acid reflux showed strong negative correlation with esophageal body motility and/or lower esophageal sphincter function. CONCLUSIONS: IEM was associated more with acid exposure, abnormal weakly acid reflux, and long term acid reflux in RGERD patients. These data suggested the role of esophageal body dysmotility in the pathophysiological mechanisms of RGERD patients.
