Abstract

BACKGROUND AND AIMS: Nutcracker esophagus is a manometric disorder with various and illusive pathophysiology including normal variant, epiphenomenon,spasm , gastroesophageal reflux and neurosis. We performed this study to evaluate psychosocial aspects in nutcracker esophagus. METHODS: We carried out MMPI and SCL-90-R tests for 24 patients with nutcracker esophagus, 9 patients with nonspecific esophageal motility disorder with low amplitude contraction, and 25 normal controls. RESULTS: The results of MMPI test for the patients with nutcracker esophagus were significantly different from those of normal controls in the hypochondriasis scale (64.5+/-7.9), depression scale (63.5+9.7), hysteria scale (65.5+/-10.0)(p<0.01). Similar differences were observed in patients with nonspecific esophageal motility disorder. The patients with nutcracker esophagus showed significant difference in the somatization scale (65.0+/-10.2), obsessive compulsive scale (55.2 +/-10.4), interpersonal sensitivity scale (52.3+/-8.5), depression scale (59.0+/-10.9), anxiety scale (59.3+/-10.0), phobia anxiety scale (54.7+/-2.5), paranoid ideation scale (47.3+/-8.2), psychoticism scale (53.5+/-7.7) of SCL-90-R test (p<0.01). The patients with nonspecific esophageal motility disorder showed similar differences in the somatization scale (60.6+/-3.6), interpersonal sensitivity scale (51.0+/-12.4), depression scale (51.0+/- 12.4), anxiety scale (55.1+/-14.9), psychoticism scale (50.6+/-11.6) of SCL-90-R test (p<0.01 and p<0.05). CONCLUSIONS: Psyehosocial aspects are associated with nutcracker esophagus. Further study is necessary to elucidate the relations between specific psychosocial aspects and nutcracker esophagus.
