RESUMEN
Objective To investigate the changes of 24 hour gastric motility and myoelectric activity in patients with functional dyspepsia (FD) and to compare the differences of these changes among the different clinical types of FD. Methods 24 hour gastric and duodenal manometry combined with 24 hour electro gastrography was carried out in 31 patietns with FD and 20 normal controls. Results Compared with normal controls, patients with FD had less frequency and longer duration of migrating motor complex (MMC), and phase Ⅰ plus phase Ⅱ duration were also greatly increased ( P
RESUMEN
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.
