Retención de cápsula endoscópica en enfermedad de Crohn ¿cómo manejarla? / Retained capsule endoscopy in Crohn´s disease: how to manage it?

Capsule endoscopy is a technique that allows the study of the small intestine, through a device that is swallowed by the patient, capturing images as it travels through the digestive tract. Capsule retention is the most serious complication. We report the case of a 69 year-old male presenting with iron deficiency anemia, with normal upper endoscopy and colonoscopy; but obscure gastrointestinal bleeding was diagnosed and therefore a study with capsule endoscopy was requested. The patient evolves with retained capsule in the small intestine with ulcerated stenosis as shown by imaging. This finding was confirmed by enteroscopy with biopsy, without being able to extract the capsule. Medical management with corticosteroids was indicated for intestinal obstruction secondary to inflammatory stenosis in the context of Crohn's disease: The capsule was expelled after 21 days of ingestion, with a positive outcome

La cápsula endoscópica es una técnica que permite el estudio del intestino delgado, mediante un dispositivo que es deglutido por el paciente y captura imágenes en su recorrido por el tubo digestivo. La complicación más grave es la retención de la cápsula. Se reporta el caso de un paciente de sexo masculino, de 69 años con anemia ferropénica, con endoscopia alta y colonoscopia normal; planteándose sangrado gastrointestinal de origen oscuro por lo que se solicita estudio con cápsula endoscópica. El paciente evoluciona con retención de la cápsula en intestino delgado, visualizándose en las imágenes la presencia de estenosis ulcerada, hallazgo que se confirma mediante enteroscopia con toma de biopsias, sin lograr extraer la cápsula. Se indica manejo médico con corticoides por obstrucción intestinal secundario a estenosis inflamatoria en contexto de enfermedad de Crohn, expulsando espontáneamente la cápsula al día 21 de su ingestión, sin complicaciones.

Retención de cápsula endoscópica en un paciente con sospecha de enfermedad de Crohn / Endoscopic capsule retention in a patient with clinical suspicion of Crohn's disease

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.

Retención de cápsula endoscópica como complicación de enteritis actínica: reporte de un caso / Retention of capsule endoscopy as a complication of radiation enteritis: a case report

La cápsula endoscópica es un método, que ha modificado el enfoque diagnóstico de numerosos procesos patológicos en el intestino delgado, sin embargo presenta complicaciones como la retención de la misma. Se estima en la literatura mundial que esta suele ocurrir en menos del 2% de los casos. Femenino de 40 años de edad, con antecedente de cáncer de cuello uterino (2011) en tratamiento con quimioterapia, radioterapia convencional y braquiterapia, que presenta cuadro clínico caracterizado por dolor urente en mesogastrio, y emesis de aspecto biliosos. Ruidos hidroaéreos presentes, dolor a la palpación de mesogastrio sin irritación peritoneal. Radiografía de abdomen y ecosonograma abdominal normales. TAC abdomino pélvica con contraste oral con adecuada progresión de contraste hasta el recto. Se practica gastroscopia y colonoscopia sin evidencia de alteraciones. En vista de persistencia de sintomatología se indica realización de cápsula endoscópica observando en íleon distal, a los 246 minutos del paso duodenal, área muy congestiva, con una úlcera circunferencial friable, que no permite el avance de la misma. Se indica tratamiento médico con laxantes por 72 horas, el cual es infructuoso, por lo cual es llevada a mesa operatoria por presentar signos francos de obstrucción intestinal. Los hallazgos fueron: adherencias en flanco y fosa ilíaca derecha, las cuales fueron liberadas, y segmento de íleon a 10 cm de la válvula ileocecal con inflamación franca, practicándose resección y anastomosis termino-lateral. El estudio histopatológico reportó enteritis crónica activa exulcerada, necrosis fibrinoide de pequeños vasos, y fibrosis en la submucosa. Paciente con post-operatorio exitoso decidiéndose el egreso de la institución. Excelente correlación entre los hallazgos de la cápsula endoscópica y la intervención quirúrgica. Los hallazgos de la cirugía se encuentran relacionados al uso de radioterapia convencional, por lo cual recomendamos la realización de pexia...

Capsule endoscopy is a method that has changed the diagnostic approach to many pathological processes in the small intestine, but it has complications such as retention of the same, is estimated in the literature that this usually occurs in less than 2% cases. Women 40 years of age, with a history of cervical cancer (2011) undergoing chemotherapy, conventional radiation therapy, and brachytherapy, presenting clinical picture characterized by burning pain in midgut, and bilious emesis aspect. Present bowel sounds, tenderness of mesogastrium without peritoneal irritation. Abdominal radiography and abdominal ultrasonography normal. Pelvic CT with oral contrast Abdomino with progression adequate contrast to the rectum. Gastroscopy and colonoscopy was performed without evidence of tampering. In view of the persistence of symptoms embodiment shown in watching endoscopic capsule distal ileum, to 246 minutes of step duodenal study, very congestive area with a circumferential friable ulcer which does not allow the advance thereof. Indicated medical treatment with laxatives for 72 hours being fruitless, operating table being carried by presenting overt signs of intestinal obstruction. The findings were: adhesions flank and right lower quadrant, which were released and ileal segment 10 cm from the ileocecal valve with frank inflammation resection and end-side anastomosis. Histopathological study reported chronic active enteritis exulcerada, fibrinoid necrosis of small vessels, and fibrosis in the submucosa. Postoperative patient deciding successful graduation from the institution. Excellent correlation between the findings of capsule endoscopy and surgery. The findings at surgery are related to the use of conventional radiotherapy, so we recommend an pexia of the organs that are in the radiation field, prior to it, and intestinal transit before indicating capsule endoscopy

Comparative study of two modes of gastroesophageal reflux measuring: conventional esophageal pH monitoring and wireless pH monitoring / Estudo comparativo de duas modalidades de mensuração do refluxo gastroesofágico: pHmetria esofágica convencional e pHmetria sem cateter

CONTEXT: Esophageal pH monitoring is considered to be the gold standard for the diagnosis of gastroesophageal acid reflux. However, this method is very troublesome and considerably limits the patient's routine activities. Wireless pH monitoring was developed to avoid these restrictions. OBJECTIVE: To compare the first 24 hours of the conventional and wireless pH monitoring, positioned 3 cm above the lower esophageal sphincter, in relation to: the occurrence of relevant technical failures, the ability to detect reflux and the ability to correlate the clinical symptoms to reflux. METHODS: Twenty-five patients referred for esophageal pH monitoring and with typical symptoms of gastroesophageal reflux disease were studied prospectively, underwent clinical interview, endoscopy, esophageal manometry and were submitted, with a simultaneous initial period, to 24-hour catheter pH monitoring and 48-hour wireless pH monitoring. RESULTS: Early capsule detachment occurred in one (4%) case and there were no technical failures with the catheter pH monitoring (P = 0.463). Percentages of reflux time (total, upright and supine) were higher with the wireless pH monitoring (P < 0.05). Pathological gastroesophageal reflux occurred in 16 (64%) patients submitted to catheter and in 19 (76%) to the capsule (P = 0.355). The symptom index was positive in 12 (48%) patients with catheter pH monitoring and in 13 (52%) with wireless pH monitoring (P = 0.777). CONCLUSIONS: 1) No significant differences were reported between the two methods of pH monitoring (capsule vs catheter), in regard to relevant technical failures; 2) Wireless pH monitoring detected higher percentages of reflux time than the conventional pH-metry; 3) The two methods of pH monitoring were comparable in diagnosis of pathological gastroesophageal reflux and comparable in correlating the clinical symptoms with the gastroesophageal reflux.

CONTEXTO: A pHmetria esofágica é considerada o melhor método diagnóstico do refluxo ácido gastroesofágico. Contudo, é bastante incômoda e restringe consideravelmente as atividades cotidianas do paciente. A pHmetria sem cateter foi desenvolvida para contornar tais limitações. OBJETIVO: Comparar as primeiras 24 horas das pHmetrias convencional e sem cateter, posicionadas a 3 cm acima do esfíncter inferior do esôfago, em relação à: ocorrência de falhas técnicas relevantes, capacidade de detecção do refluxo e capacidade de relacionar as queixas clínicas com o refluxo. MÉTODOS: Foram estudados, de modo prospectivo, 25 pacientes encaminhados para pHmetria esofágica, com sintomas típicos da doença do refluxo gastroesofágico, submetidos a entrevista clínica, endoscopia digestiva, manometria esofágica e realização, com período inicial simultâneo, de pHmetrias com cateter por 24 horas e com cápsula por 48 horas. RESULTADOS: Houve queda precoce da cápsula em um paciente (4%) e nenhuma falha técnica na pHmetria com cateter (P = 0,463). As percentagens de tempo de refluxo (total, ortostático e supino) foram mais elevadas na pHmetria sem cateter (P<0,05). Refluxo gastroesofágico patológico foi diagnosticado em 16 (64,0%) pacientes com o cateter e em 19 (76,0%) com a cápsula (P = 0,355). O índice de sintomas foi positivo em 12 (48%) pacientes na pHmetria com cateter e em 13 (52%) na pHmetria sem cateter (P = 0,777). CONCLUSÕES: 1) Não há diferença significante entre as duas modalidades de pHmetria (cápsula vs cateter), em relação à ocorrência de falhas técnicas relevantes durante o exame; 2) A pHmetria sem cateter detecta refluxo em percentagens superiores às detectadas pela pHmetria convencional; 3) Os dois métodos de pHmetria têm capacidades semelhantes de diagnóstico de refluxo gastroesofágico patológico e capacidades semelhantes de relacionar as queixas clínicas com o refluxo gastroesofágico.

Impact of prolonged 48-h wireless capsule esophageal pH monitoring on diagnosis of gastroesophageal reflux disease and evaluation of the relationship between symptoms and reflux episodes / Impacto da monitorização prolongada do refluxo por pHmetria sem cateter por 48 horas, no diagnóstico da doença do refluxo gastroesofágico e no estudo da relação entre os sintomas e o refluxo

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.
