La videocápsula endoscópica es un procedimiento de diagnóstico que visualiza el tracto gastrointestinal utilizando una pequeña cápsula inalámbrica resistente a las enzimas que traga el paciente.
Se recomienda para diagnosticar afecciones como la enfermedad de Crohn, los pólipos y la enfermedad celíaca.
Antes del procedimiento: El paciente se somete a una limpieza intestinal con laxantes recetados y mantiene la NPO durante ocho horas para garantizar una visualización clara del tracto gastrointestinal.
Durante el procedimiento, se colocan sensores adhesivos en el tórax y el abdomen del paciente.
Estos sensores se conectan a un registrador de datos inalámbrico que captura las señales de la cápsula.
El paciente traga la cápsula con agua y puede reanudar sus actividades normales después.
Dos horas después de la ingestión de la cápsula, se permite una dieta de líquidos claros; después de cuatro horas, se toma un refrigerio ligero y medicamentos.
La cápsula tarda unas ocho horas en pasar a través del tracto digestivo, capturando imágenes.
Después del procedimiento: Se retiran el sensor y la grabadora para analizar las imágenes.
Por lo general, la cápsula se expulsa de forma natural en unas pocas horas a cinco días. Los pacientes deben notificar a su proveedor de atención médica si no ha pasado después de cinco días.

Q1: What is video capsule endoscopy and how does it work?
Video capsule endoscopy is a diagnostic procedure using a small, swallowable wireless capsule equipped with a transmitter, battery, LED light, and color video camera. The capsule captures images throughout the gastrointestinal tract and transmits them to a wireless data recorder worn at the patient's waist. It travels through the digestive system over approximately eight hours, providing detailed visualization of areas difficult to reach with traditional endoscopy.
Q2: What conditions can video capsule endoscopy diagnose?
Video capsule endoscopy diagnoses Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained gastrointestinal bleeding, abdominal pain, and celiac disease. The procedure's ability to visualize the entire gastrointestinal tract makes it particularly useful for identifying sources of bleeding and inflammatory conditions that may not be visible through other diagnostic methods.
Q3: How should patients prepare for video capsule endoscopy?
Patients must maintain NPO status for eight hours before the procedure to ensure an empty stomach. The evening before, laxatives are administered to cleanse the bowel thoroughly. On the procedure day, a technician attaches adhesive sensors to the patient's chest and abdomen, which connect to a wireless data recorder worn at the waist for capturing capsule signals.
Q4: What can patients do during video capsule endoscopy?
After swallowing the capsule with water, patients resume normal daily activities but should avoid strenuous exercise, sudden movements, or bending for eight hours. Two hours post-ingestion, patients may drink clear liquids; after four hours, they can consume light snacks and take medications. The capsule travels through the gastrointestinal tract capturing images stored in the data recorder throughout this period.
Q5: What happens after video capsule endoscopy is completed?
Eight hours post-ingestion, patients return to the medical facility to have the sensors and data recorder removed. Healthcare providers analyze the captured images to identify abnormalities. The capsule is typically expelled naturally within a few hours to five days through bowel movements. Patients should contact their healthcare provider if the capsule has not passed within five days.
Q6: Are there any restrictions after video capsule endoscopy?
There are no restrictions following video capsule endoscopy, and patients can resume their normal activities immediately after the procedure. A follow-up appointment is typically scheduled to discuss the results and any findings from the captured images. Most patients experience no complications or side effects post-procedure.
Q7: How does video capsule endoscopy differ from other gastrointestinal diagnostic procedures?
Unlike traditional endoscopic procedures that use inserted instruments, video capsule endoscopy is non-invasive and wireless. The capsule visualizes the entire gastrointestinal tract without requiring sedation or instrument insertion. This makes it ideal for examining areas like the small intestine that are difficult to access with conventional endoscopy, offering comprehensive diagnostic capability with minimal patient discomfort.
