ABSTRACT

Presentamos 3 casos de pacientes que necesitaron cirugía a causa de un bezoar secundario a la ingesta de cabellos y otras sustancias no nutritivas (cerdas de cepillos) en el contexto de un trastorno de control de impulsos, en el que suele haber ansiedad previa a la ingesta, la misma que disminuye con el acto de ingerir estos elementos. Se revisa el concepto de impulsos irresistibles sistemáticos, la neurobiología y tratamiento de la impulsividad, y la relación de ésta con los denominados trastornos del espectro obsesivo-compulsivo. Por último, se resalta el papel del entorno familiar y social en el desarrollo y pronóstico del cuadro clínico de las pacientes.


We present 3 cases of patients who had to undergo surgery due to a bezoar that was secondary to the ingestion of hair and other non-nutritive substances (brush bristles) in the context of an impulse-control disorder, where there is often anxiety prior to intake that decreases with the act of eating these elements. We reviewed the concept of irresistible systematic impulses, the neurobiology and treatment of impulsivity, and the relation of this syndrome with the so-called obsessive-compulsive spectrum disorders. Finally, the role of the family and the social environment are highlighted in the development and prognosis of the patientsÆ clinical syndrome.
