Hypercontracting (nutcracker) esophagus

Manometrically

jackhammer esophagus with fluoroscopically/endoscopically distal esophageal spasm: a case report. High-resolution esophageal manometry representative of the patient’s swallows. The median integrated relaxation pressure (IRP) was borderline high at 15.5 mmHg, a distal latency (DL) was normal at 6.5 s and the mean distal contractile integral (DCI) was elevated to 14,458 mmHg-s-cm. High amplitude peristaltic esophageal contraction with a DCI > 8000 mmHg-s-cm represented the hypercontractile (JH) esophagus

esophageal motility study for nutcracker esophagus. The image on the left is a schematic of the esophagus and three pressure recordings are taken: at the upper esophagus, lower esophagus and lower esophageal sphincter. The graph at the top indicates the time of two swallows. The disorder is peristaltic, with high pressure esophageal contractions exceeding 180 mmHg. The contractile waves have a long duration exceeding 6 seconds. -- Samir धर्म 09:00, 11 September 2006 (UTC)

Hypercontracting (nutcracker) esophagus is a motility disorder of the esophagus. This condition is primarily diagnosed with manometry with high intra-esophageal pressure and normal peristalsis. Most patients will have a normal barium swallow.

Hypercontracting esophagus ("nutcracker esophagus") differs from diffuse esophageal spasm (corkscrew esophagus) but doesn't exclude each other.
