We report the CT findings of diffuse esophageal spasm (DES) in a patient with dysphagia. Although an uncommon condition, DES should be included in the differential diagnosis if relatively long and symmetric segmental esophageal wall thickening and an epiphrenic esophageal diverticulum are noted at CT.

Esophageal high-resolution manometry (HRM) is replacing conventional manometry in the clinical evaluation of patients with esophageal symptoms, especially dysphagia. The introduction of HRM gave rise to new objective metrics and recognizable patterns of esophageal motor function, requiring a new classification scheme: the Chicago classification. HRM measurements are more detailed and more easily performed compared to conventional manometry. The visual presentation of acquired data improved the analysis and interpretation of esophageal motor function. This led to a more sensitive, accurate, and objective analysis of esophageal motility. In this review we discuss how HRM changed the way we define and categorize esophageal motility disorders. Moreover, we discuss the clinical applications of HRM for each esophageal motility disorder separately.

OBJECTIVES: Nonspecific esophageal motility disorder(NEMD) is a vague category used to group poorly defined contraction abnormalities. We evaluated the clinical characteristics and esophageal transit time (ETT) in patients with NEMD. METHODS: Total 205 patients with NEMD were compared with 20healthy controls and 99patients with other motility disorders of the esophagus. Esophageal manometry was performed with a lowcompliance pneumohydraulic capillary infusion system and esophageal scintigraphy was performed for the liquid and solid swallow after manometric study. RESULTS: 1) Among the total 258abnormal contractions in 205patients with NEMD, non-transmitted contractions were 125(45.5%), low amplitude 110(42.6%), triple peaked 3(1.2%), prolonged duration contractions 12(4.7%) and isolated incomplete LES relaxation 8(3.1%). 2) NEMD patients have significantly delayed ETT similar to that seen in patients with diffuse esophageal spasm, nutcracker esophagus, hypertensive lower esophageal sphincter for liquid, and diffuse esophageal spasm, hypertensive lower esophageal sphincter for solid. 3) ETT for liquid and solid according to abnormal contractions were 39.0 and 55.6seconds in non-transmitted, 38.3, 68.4 seconds in low amplitude, 17.0, 30.0 seconds in triple peaked, 29.4, 25.8 seconds in prolonged-duration contractions and 13.7, 15.5 seconds in isolated incomplete LES relaxation, respectively. CONCLUSION: Patients with NEMD have significantly delayed ETT for liquid and solid compare to normal control. The main abnormal contractions of NEMD were non-transmitted and low amplitude contractions. And low amplitude contractions were the main cause of delayed solid transit in patients with NEMD(p<0.01).

Diffuse esophageal spasm (DES) is a rare disease seen in 4% of all patients studied in an esophageal motility laboratory, and its diagnosis and surgical management is still controversial. Recently, we treated two patients by extended esophageal myotomy for diffuse esophageal spasm which was diagnosed by the clinical symptoms of patients, esophagoscopy, esophagography, and esophageal manometry. The successful result of treatments was proved with subsidence of previous clinical symptoms (dysphagia and chest pain), postoperative esophagography and esophageal manometry. We present the results together with the review of literatures.

The aim of this study was to assess changes between primary classification of esophageal motility disease and follow-up classification by high resolution manometry (HRM) and to determine whether previously classified diseases could be recategorized according to the updated Chicago Classification published in 2011. We reviewed individual medical records and HRM findings twice for each of 13 subjects. We analyzed primary and follow-up HRM findings based on the original Chicago Classification. We then reclassified the same HRM findings according to the updated Chicago Classification. This case series revealed the variable course of esophageal motility disorders; some patients experienced improvement, whereas others experienced worsening symptoms. Four cases were reclassified from variant achalasia to peristaltic abnormality, one case from diffuse esophageal spasm to type II achalasia and one case from peristaltic abnormality to variant achalasia. Four unclassified findings were recategorized as variant achalasia. In conclusion, esophageal motility disorders are variable and may not be best conceptualized as an independent group. Original classifications can be recategorized according to the updated Chicago Classification system. More research is needed on this topic.

Diffuse esophageal spasm (DES) is a motility disorder of the esophagus characterized by symptoms of retrosternal chest pain and intermittent dysphagia. The diagnosis of DES has relied on criteria obtained from a standard esophageal manometry (more than one simultaneous contraction in a series of 10 wet swallows with the rest being peristaltic). Because symptoms and/or typical manometric findings are not always documented during the standard manometry, 24 hour manometry may be more useful in such cases. We recently assessed a 29-year-old male patient who complained of chest pain and dysphagia. He showed nonspecific findings on the laboratory based manometry, but DES was diagnosed by his typical manometric findings on the 24 hour manometry. Therefore, a 24 hour manometry should always be performed when the patient's history suggests the presence of DES and the laboratory based manometry failed to detect the symptomatic contractions of DES. Following we report this case with a review of the literature.

Diffuse esophageal spasm (DES) is an uncommon motility disorder of unknown etiology in which the abnormal motility has been offered as a possible cause for the patient's dysphagia or chest pain. Esophageal manometry is the gold standard for the diagnosis of DES and the diagnostic hallmark is identification of simultaneous contractions in at least 20% of wet swallows, alternating with normal peristalsis. Recently, a new diagnostic technique, high-resolution manometry has been reported to improve the accuracy and detail in describing esophageal function. We report a female patient with intermittent dysphagia and chest pain occurring only when swallowing a large amount of water. On HRM, this patient had esophageal spasms, increased pressurization front velocity attributable to rapid contractile wave front, associated with symptoms, which were provoked by a multiple rapid swallowing test, and thereby was diagnosed with DES.

BACKGROUND/AIMS: Some patients complaining chest pain have normal coronary angiograms. In these cases of noncardiac chest pain, esophageal disease might be a reasonable explanation. However, causal relationship between esophageal motility or reflux disease and chest pain may be difficult to be proven. Therefore, we performed this study to evaluate the esophageal abnormality as a potential cause of noncardiac chest pain. METHODS: We underwent esophagogastroduodenoscopy, esophageal mancenetry and 24 hour esophageal pH monitoring in 58 patients with chest pain and normal coronary arteriogram or negative thallium study. RESULTS: Of 58 patients, 17 patients (29.3%) had abnormal esophageal manometry test. There were 6 cases of nonspecific esophageal motility disorder, 5 cases of hypertensive lower esophageal sphincter, 5 cases of diffuse esophageal spasm and 1 case of nutcracker esophagus. In 56 patients with 24 hour pH monitoring, 13 patients had positive DeMeester score and 29 patients experienced chest pain during the test period. 11 patients (18.9%) had both positive DeMeester score and chest pain. Mean symptom index of these patients was 70.0% (range 40-100%). CONCLUSIONS: Esophageal motility disorders and gastroesophegeal reflux diseases were frequantly found in patients with noncardiac chest pain. Much efforts should be made to find esophageal cause in patients with noncardiac chest pain.
