corkscrew and corkscrew oesophagus (CO)


A popular term for a neurogenic disorder characterised by peristaltic contractions of the lower oesophagus, which bears a marked visual similarity* to a corkscrew. The spams occur spontaneously or are evoked by swallowing or gastric acid reflux

*Unlike a lot of the signs out there, where ya gotta stand on your friggin’ head to kinda see a vague similarity of whatever to the whatever sign

Clinical findings Dysphagia, weight loss, severe epigastric pain  (the corkscrew oesophagus triad),  retrosternal pain, increased intraluminal pressure, uncoordinated muscle contractions, and weight loss; it may be asymptomatic; in the lower oesophagus, the contractions may increase intraluminal pressure, producing transient pseudodiverticuli 

Imaging Radiocontrast studies reveal periodically spaced, high-amplitude spastic peristaltic contractions of the lower oesophagus (left image, corkscrew; right image, plain film of CO with contrast)

Pathogenesis CO is attributed to muscle hyperresponsiveness to neurotransmitters or hormones 

Management Antispasmodics, avoidance of cold fluids, dilation, myotomy

Synonyms Asymptomatic functional diverticulum of the oesophagus, Bársony-Polgár syndrome II, Bársony-Teschendorf syndrome, corkscrew esophagus, diffuse esophageal spasm, diffuse oesophagus spasm, diffuse oesophageal spasm, diffuse oesophagus spasm, diffuse spasm of oesophagus, diffuse spasm of oesophagus, idiopathic diffuse esophageal spasm, idiopathic diffuse oesophageal spasm
