What causes weak peristalsis?
What causes weak peristalsis?
Background Weak and absent esophageal peristalsis are frequently encountered esophageal motility disorders, which may be associated with dysphagia and which may contribute to gastroesophageal reflux disease.
What is decreased esophageal motility?
Esophageal motility disorders involve dysfunction of the esophagus that causes symptoms such as dysphagia, heartburn, and chest pain. (See also Overview of Esophageal and Swallowing Disorders.)
Are there any nonspecific esophageal motility disorders?
CONCLUSION. Esophageal dysmotility was found in nine (7%) of 138 patients after laparoscopic Nissen fundoplication, including secondary achalasia in three (33%), diffuse esophageal spasm (DES) in two (22%), and a nonspecific esophageal motility disorder in four (44%).
How are barium esophagrams used to diagnose motility?
Barium esophagrams detect anatomical lesions and mucosal changes, but provide only qualitative assessment of motility. Esophageal manometry directly measures esophageal pressure, peristalsis, and sphincter contraction and relaxation.
What causes proximal escape of barium in the esophagus?
Occasionally, so-called proximal escape of barium occurs at the level of the aortic arch ( Fig. 18-5 ). This age-related phenomenon is caused by a low-amplitude pressure trough at the transition zone between the striated and smooth muscle portions of the esophagus, which prevents closure of the esophageal lumen and allows retrograde flow of barium.
What causes secondary achalasia and other esophageal motility disorders?
Secondary Achalasia and Other Esophageal Motility Disorders After Laparoscopic Nissen Fundoplication for Gastroesophageal Reflux Disease. This motility disorder could result from prolonged mechanical obstruction of the distal esophagus by the fundoplication wrap, with loss of peristalsis above the wrap.
What are weak and absent esophageal motility disorders?
Background Weak and absent esophageal peristalsis are frequently encountered esophageal motility disorders, which may be associated with dysphagia and which may contribute to gastroesophageal reflux disease. Recently, rapid developments in the diagnostic armamentarium have taken place, in particular, in high-resolution manometry with or with-

How to diagnose barium stasis in esophagus?
Barium stasis in the esophagus > 15 s or alterations in the primary or secondary stripping wave are indications of IEM. The degree of peristaltic abnormality is classified as mild, severe (profound), or absent. In patients with profound esophageal dysmotility, it is essential to recognize the presence of any stripping wave.
