ABSTRACT

The role of Helicobacter pylori (Hp) in Non Ulcer Dyspepsia (NUD) has been a controversial issue. OBJECTIVES: 1) To determine the frequency of Upper Gastrointestinal Endoscopy (UGE) in patients suffering NUD in whom endoscopy was indicated in our Service, 2) To determine the prevalence of infection by Hp in patients with NUD in whom endoscopy was done, 3) To find an association of clinical and historical facts among patients with and without Hp infection. POPULATION AND SAMPLE: 91 consecutive patients, free of esophageal or gastro-intestinal organic disease by endoscopic criteria from a total of 132, in a period of six months. 47 men (X age: 50.4 years, SE 2.6, SD 17.3) and 44 women (X age 49.7 years, SE 2.5, SD 16.8), Levene's Test p = 0.91. Descriptive, comparative and correlation, transverse simple-blind. METHODS: 1) two endoscopic biopsies for Hp (antrum and corpus), Rapid Hp Urease Test (modified Christensen protocol) with immediate and 6-hours later readings; 2) two samples for histopathologic diagnosis of Hp (antrum and corpus) with H&E, Giemsa or Warthin-Starring. STATISTICS: Levene Test for homogeneity of variance, descriptive statistic tests, ANOVA, chisquare, contingency coefficient, Pearson's r, Run Tests. Alpha level = 0.05. RESULTS: 91 out 132 patients were included (69.9 per cent). Prevalence was greater in men (p = 0.04). Run Tests for variables between 0.34 and 0.76, 45 patients were positives (+) for one or two methods (49.5 per cent). There were significative differences between the means for variable age for the groups (+) and (-) at the moment of the study (+, mean age 45 years old, SE 2.4; negative tests, mean age 55 years old, SE 2.5, p = 0.005). Wide data dispersion (Coefficient of Pearson = 34.5 per cent). There was association between age symptoms onset and positive tests (mean 40.4 years old, SE 2.6, Coefficient of Pearson 43 per cent) and negative tests (mean 48.9 years old, SE 2.6, Coefficient of Pearson 36 per cent) (p = 0.02). There were also association between age and + tests (p = 0.005). Non statistically significant differences were found between time of evolution of symptoms (p = 0.49), prevalence between sexes of symptoms (although nearly significant, p = 0.06), presence of unespecific pain (p = 0.16), ulcer-like pain (p = 0.46), plenty sensation, distension, satiety (p = 0.64) and differences by sex and age in symptoms (p = 0.55).

ABSTRACT

El esófago es origen de varias formas de sensibilidad dolorosa. La sensorialidad sigue las leyes de la sensibilidad visceral general con algunas variantes individuales. Se estudiaron las áreas de proyección del dolor despertado por la distensión progresiva de un balón a intervalos de c cm., desde los 38 a los 22 cmn. de la A.D.S. Se registró el número de respuestas en cada una de las 13 zonas frontales y 10 dorsales en que se dividió arbitrariamente el tórax, e incluyendo al epigastrio y la base del cuello. Se consideró la primera respuesta a la distinsión, o hasta un máximo de 15 ml. de aire (diámetro del balón=3.2 cm). Se estudiaron 101 pacientes (controles y con síntomas esofágicos no orgánicos, con excepción de la esofagopatía por reflujo). Se obtuvieron 1153 respuestas en total en los 9 niveles estimulados, de las cuales el 93.8 por ciento se presentaron en las zonas frontales, y de ellas el 82.4 por ciento en las áreas mediales (epigastrio a base del cuello). No se encontraron diferencias entre los sexos. El esófago inferior fue significativamente menos sensible que el superior. El número de proyecciones hacia el tórax superior fue proporcionalmente mayor que su inversa. Se encontraron modelos individuales que resultarían útiles frente a un paciente en particular. Conclusiones: a) el esófago no es igualmente sensible a toda su extensión; b) la proyección metamérica es múltiple y predomina ampliamente en el plano frontal; c) la existencia de "zonas de gatillo" puntuales obliga a estudiar toda la extension del esófago cuando se utiliza la prueba como test diagnóstico
