ABSTRACT

BACKGROUND: Constipation is a common problem in the general population and its prevalence is based on the diagnostic criteria, the study population and the research methodology for collecting the data. OBJECTIVES AND METHODS: To establish the clinical gudelines for diagnosis and treatment of chronic constipation in Mexico we have reviewed the epidemiological factors of constipation and have conducted meta-analysis according to the 3 available community-based studies from our country. In addition, evidence-based recommendations have been provided. RESULTS: The estimated prevalence of functional constipation in Mexico is 14.4% (95% CI: 12.6-16.6%) according to Rome II and Rome III criteria. Although constipation is present in both genders and all age groups, it is more common among young women with a female to male ratio of 3:1. In our population, 43.6% report using laxatives, teas for stimulating bowel movements or fiber supplements, but only 18.0% did so because they considered themselves as constipated. Also, data from a tertiary referral center in Mexico City suggests that patients with prolonged colonic transit time have lower scores in the physical component of the SF-36 compared to those with chronic constipation and a normal colonic transit time. CONCLUSIONS: Functional constipation is a very common problem in Mexico affecting mainly young women. Laxatives and other related agents are frequently used and this disorder seems to have a negative impact on quality of life.

ABSTRACT

Entre octubre de 1990 y diciembre de 1994, se valoraron 200 pacientes en quienes se colocó endoprótesis en la vía biliar. La distribución por sexo fue de 102 mujeres y 98 hombres, con rangos de edad entre los 18 y los 94 años. Las indicaciones para el procedimiento fueron: obstrucción biliar maligna en 96 casos, coledocolitiasis de difícil manejo en 47, estenosis iatrogénica de la vía biliar en 27, fístula biliar en 12, compresión de colédoco por pancreatitis crónica en nueve, por pancreatitis aguda en seis, colangitis supurativa en dos y un paciente con estenosis de la papila de Vater. Inmediatamente después de la colocación de las prótesis se observó drenaje adecuado de bilis al duoneno. Como complicaciones, se presentaron cinco migraciones, 14 cuadros de obstrucción de las prótesis con colangitis subsecuente, una hemorragia secundaria a esfinterotomía y una prancreatitis grave con defunción. Se concluye que la colocación de endoprótesis es de gran utilidad para mantener permeable la vía biliar. Las pocas complicaciones en manos esperimentadas, su bajo costo y mínima morbimortalidad, la hacen el método de primera elección en los procesos obstructivos de la vía biliar.
