This is due to clinical evaluation of obstructive symptoms and abdominal examinations by gastroenterologists and nurses for patients prior to performance of CE. In addition, administration of NSAIDs and abdominal radiation were discontinued two months prior to performance of CE. Radiological studies of and the small intestinal were done prior to CE performance for patients suspected of having an intestinal obstruction or Crohn's disease.
Además, se descarta ingesta de AINE's en los dos meses previos al estudio, antecedentes de radiación abdominal y se solicitan estudios radiológicos de intestino delgado previo a la realización de CE en pacientes con sospecha clínica de obstrucción intestinal y enfermedad de Crohn, este último es responsable de una tercera parte de las CE retenidas según se ha descrito en la literatura 6.
