RESUMO

The "Nutcracker esophagus " (NE) is a disease of manometric diagnosis, described in 1977, characterized by hypercontractility esophageal body. In the 1990s, there were publications relating the NE to gastroesophageal reflux disease (GERD), which has since been the subject of controversy. Such controversy and a lack of studies evaluating reflux in less intense form of hypercontractility motivated the present study. OBJECTIVES: To study patients with clinically suspected reflux and esophageal body hypercontractility, classified according to their intensity: mild and severe, in relation to demographic data, clinical manifestations, endoscopic, manometric and pH monitoring findings. In parallel, the objective is to evaluate the same parameters in a reference group composed of individuals without typical complaints of reflux and without endoscopic and esophageal manometry abnormalities. METHODS: It was selected, retrospectively, to compose the study group, patients with esophageal body hypercontractility at the manometric study, classified according to their intensity into two sub-groups: I. hypercontractility discrete (154-180 mmHg) and II. hypercontractility sharply - NE (>180 mmHg). It was also evaluated, a reference group (III), composed of individuals without typical complaints of GERD and without endoscopic and esophageal manometry abnormalities. We analyzed demographic, clinical, endoscopic, manometric and pH monitoring findings. RESULTS: One hundred and eight subjects were enrolled: 29 patients in Group I, 58 in Group II and 21 in Group III. Females predominated in all groups, no statistically significant difference between them. In relation to the predominant clinical complaints, no significant difference between groups regarding the occurrence of typical complaints (GI: 58.6% x GII: 50.0%) and for the presence of atypical complaints (GI: 13.8 %, GII: 29.3% and GIII: 14.3%). The reference group showed significantly higher incidence of extra-esophageal complaints (GI: 27.6%, GII: 20.7% and GIII: 47.6%) and "other complaints" (GI: 0.0%, GII: 0.0% and GIII: 38.0%). Regarding the endoscopic findings, we observed that the occurrence of esophagitis was significantly greater in Group I (76.2% x 46.3%). The occurrence of pathological reflux, with pH monitoring, was GI: 44.8%, GII: 36.2% and GIII: 19.0%. Despite this higher incidence of pathological reflux in the study groups (GI and GII), this difference did not reach statistical significance levels. CONCLUSIONS: No significant difference between patients with mild and severe hypercontractility esophageal body in relation to demographic, clinical, manometric and pH monitoring findings. There is a significant difference only in relation to the occurrence of endoscopic esophagitis, which predominates in patients with mild hypercontractility. There is no significant difference between patients with esophageal hypercontractility body when compared with those without hypercontractility in relation to demographic data, occurrence of atypical complaints and presence of gastroesophageal reflux. Among the parameters evaluated, there was significant difference only in relation to the occurrence of extra-oesophageal complaints and other complaints suggestive of reflux predominantly in patients without hypercontractility. Patients with esophageal hypercontractility body tend to have gastroesophageal reflux in excess of those that do not have hypercontractility. However, with the sample size was not possible to confirm this hypothesis
