ABSTRACT

INTRODUCCIÓN: La cápsula endoscópica (CE) es a una técnica no invasiva que permite la visualización de la mucosa del intestino delgado. Se utiliza para el diagnóstico de lesiones no accesibles con otros exámenes. El objetivo fue describir la experiencia de uso de CE en un hospital público pediátrico en Chile. PACIENTES Y MÉTODO: Estudio retrospectivo en que se revisaron los casos en que se utilizó CE en el Hospital Dr. Luis Calvo Mackenna desde 2010 hasta la fecha. Se registraron datos demográficos, clínicos, hallazgos, complicaciones, diagnóstico y conducta. RESULTADOS: Se realizaron 20 procedimientos en 16 pacientes, 11 varones (69%), mediana de edad 12 años (rango 3 a 15 años). Las indicaciones incluyeron estudio de poliposis (60%), sospecha de enfermedad de Crohn (20%), hemorragia digestiva de origen desconocido (15%) y anemia de causa desconocida (5%). Diecisiete estudios estaban alterados (85%) y 11 llevaron a un diagnóstico o cambio de conducta clínica (55%). Los hallazgos principales fueron pólipos y erosiones intestinales. No se produjeron complicaciones. CONCLUSIONES: La CE es una técnica útil y segura en niños, factible de realizar en un hospital público pediátrico.


INTRODUCTION: Capsule endoscopy (CE) is a non-invasive technique that allows visualization of small intestine mucosa. It is used for diagnosis of lesions not accessible with other tests. Our goal was to describe the experience using CE in a pediatric public hospital in Chile. PATIENTS AND METHOD: A retrospective study was carried out to review the cases in which CE was used at Dr. Luis Calvo Mac kenna Hospital from 2010 to date. Demographic and clinical data, findings, complications, diagnosis and treatment were recorded. RESULTS: Twenty procedures were performed in 16 patients, 11 men (69%), median age 12 years (range 3 to 15 years). Indications included polyposis study (60%), suspected Crohn disease (20%), obscure gastrointestinal bleeding (15%) and undiagnosed anemia (5%). Seventeen studies were altered (85%) and 11 led to a diagnosis or clinical behavior change (55%). There were no complications. CONCLUSIONS: CE is a useful and safe technique in children, feasible to perform in a pediatric public hospital.

ABSTRACT

The endoscopic capsule is classically used in the study of occult bleeding, but has recently been shown to be useful in the diagnosis and follow-up of Crohn's disease. The retention of the capsule is the most frequent complication related to its use. We report the case of a 30-year-old male patient with recurrent abdominal pain and suspected Crohn's disease. A procedure with a video endoscopic capsule was performed; twelve hours after its ingestion, the patient goes to the emergency department due to worsening of the pain. Abdominal and pelvic CT demonstrates multiple areas of segmental parietal thickening of the ileum and a metallic foreign body in an area of stenosis corresponding to the retained endoscopic capsule. It evolves with persistent pain despite pharmacological therapy. Subsequently it is extracted by enteroscopy. The indications and risks of the use of the endoscopic video capsule, and the clinical and imaging factors predictive of retention are discussed.


La video cápsula endoscópica se utiliza clásicamente en el estudio de sangrado oculto, pero últimamente se ha demostrado su utilidad en el diagnóstico y seguimiento de la enfermedad de Crohn. La retención de la cápsula es la complicación más frecuente relacionada a su uso. Se presenta el caso de un paciente de sexo masculino de 30 años con dolor abdominal recurrente y sospecha de enfermedad de Crohn. Dentro del estudio se le realiza una video cápsula endoscópica; doce horas posteriores a su ingesta consulta en el servicio de urgencia por empeoramiento del dolor. La tomografía computada de abdomen y pelvis demuestra múltiples áreas de engrosamiento parietal segmentarias del íleon y un cuerpo extraño metálico en un área de estenosis, correspondiente a la cápsula endoscópica retenida. Evoluciona con persistencia del dolor pese a la terapia farmacológica. Posteriormente se procede a su extracción mediante enteroscopia. Se discuten las indicaciones y riesgos del uso de la video cápsula endoscópica, y los factores clínicos e imagenológicos predictores de retención.

ABSTRACT

Muito do diagnóstico e tratamento das patologias do intestino delgado tem sido discutido e estudado na última década, desde a introdução da cápsula endoscópica na prática médica. Esta importante inovação tecnológica possibilitou o rompimento da última fronteira endoscópica do trato digestivo, permitindo o acesso endoscópico a toda a extensão do intestino delgado, o qual, devido a suas peculiaridades anatômicas e extensão, permanecia acessível somente à enteroscopia intraoperatória.


Both diagnosis and treatment of small intestine pathology has been discussed and studied in last decade since the introduction of endoscocopy capsule in medical practice. This important technological innovation allowed to break the last endoscopy borderline of digestive tract permitting endoscopy access for all extent of small intestine which due its anatomical peculiarities and extent remained accessible only to intraoperative enteroscopy.

ABSTRACT

CONTEXT: Gastroesophageal reflux disease is one of the most common digestive diseases and an important cause of distress to patients. Diagnosis of this condition can require ambulatory pH monitoring. OBJECTIVES: To determine the diagnostic yield of a wireless ambulatory pH monitoring system of 48-hours, recording to diagnose daily variability of abnormal esophageal acid exposure and its symptom association. METHODS: A total of 100 consecutive patients with persistent reflux symptoms underwent wireless pH capsule placement from 2004 to 2009. The wireless pH capsule was deployed 5 cm proximal to the squamocolumnar junction after lower esophageal sphincter was manometrically determined. The pH recordings over 48-h were obtained after uploading data to a computer from the receiver that recorded pH signals from the wireless pH capsule. The following parameters were analyzed: (1) percentual time of distal esophageal acid exposure; (2) symptom association probability related to acid reflux. The results between the first and the second day were compared, and the diagnostic yield reached when the second day monitoring was included. RESULTS: Successful pH data over 48-h was obtained in 95 percent of patients. Nearly one quarter of patients experienced symptoms ranging from a foreign body sensation to chest pain. Forty-eight hours pH data analysis was statistically significant when compared to isolated analysis of day 1 and day 2. Study on day 2 identified seven patients (30.4 percent) that would be missed if only day 1 was analyzed. Three patients (18.7 percent) out of 16 patients with normal esophageal acid exposure on both days, showed positive symptom association probability, which generated an increase in diagnostic yield of 43.4 percent. CONCLUSION: Esophageal pH monitoring with wireless capsule is safe, well tolerated, does not require sedation. The extended 48-h period of study poses an increased yield to diagnose gastroesophageal reflux disease patients.


CONTEXTO: A doença do refluxo gastroesofágico é uma das doenças digestivas mais comuns e importante causa de desconforto para os pacientes. O diagnóstico desta condição clínica pode requerer monitoramento ambulatorial do pH esofágico. OBJETIVOS: Determinar o espectro diagnóstico do sistema de monitoramento ambulatorial do pH esofágico com cápsula telemétrica por um período de 48 horas no diagnóstico da variabilidade diária da exposição ácida anormal e sua associação com sintomas. MÉTODOS: Foram incluídos 100 pacientes adultos, consecutivos, com sintomas relacionados com a doença do refluxo gastroesofágico, que realizaram pHmetria com cápsula telemétrica por 48 horas entre 2004 e 2009. A cápsula foi posicionada e implantada a 5 cm da borda superior do esfíncter esofágico inferior, definida pela manometria esofágica. Foram analisados os seguintes parâmetros: (1) tempos percentuais de exposição ácida no esôfago distal; (2) probabilidade de associação dos sintomas com o refluxo ácido. Foram comparados os resultados entre o 1º e o 2º dia de monitoramento, assim como o eventual ganho diagnóstico obtido após a inclusão do 2º dia no monitoramento. RESULTADOS: Sucesso na obtenção dos dados do pH esofágico durante 48 horas foi obtido em 95 por cento dos pacientes. Aproximadamente 25 por cento dos pacientes apresentaram sintomas relacionados à implantação da cápsula, variando entre sensação de presença de corpo estranho à dor torácica. A análise dos resultados do estudo de 48 horas mostrou-se estatisticamente significante quando comparada com as análises isoladas do dia 1 e do dia 2. O estudo do dia 2 identificou sete pacientes (30.4 por cento) que teriam sido perdidos se somente o dia 1 fosse analisado. Três pacientes (18.7 por cento) dos 16 pacientes com exposição ácida normal no esôfago distal em ambos os dias, apresentaram probabilidade de associação com o sintoma positivo, que gerou incremento no ganho diagnóstico com este método diagnóstico de 43.4 por cento. CONCLUSÕES: O monitoramento do pH esofágico com a cápsula telemétrica é seguro, bem tolerado e não requer sedação. A extensão do período de estudo para 48 horas representa significativo aumento no ganho diagnóstico em pacientes com doença do refluxo gastroesofágico.
