L'endoscopia con videocapsula è una procedura diagnostica che visualizza il tratto gastrointestinale utilizzando una piccola capsula wireless resistente agli enzimi ingerita dal paziente.
Si raccomanda di diagnosticare condizioni come il morbo di Crohn, i polipi e la celiachia.
Pre-procedura: il paziente viene sottoposto a pulizia intestinale con lassativi prescritti e mantiene NPO per otto ore per garantire una chiara visualizzazione del tratto gastrointestinale.
Durante la procedura, i sensori adesivi sono attaccati al torace e all'addome del paziente.
Questi sensori si collegano a un registratore di dati wireless che cattura i segnali dalla capsula.
Il paziente deglutisce la capsula con acqua e può riprendere le normali attività in seguito.
Due ore dopo l'ingestione della capsula, è consentita una dieta liquida chiara; dopo quattro ore, vengono assunti uno spuntino leggero e farmaci.
La capsula impiega circa otto ore per passare attraverso il tratto digestivo, catturando le immagini.
Post-procedura: il sensore e il registratore vengono rimossi per analizzare le immagini.
La capsula viene in genere espulsa naturalmente entro poche ore o cinque giorni. I pazienti devono informare il proprio medico se non è passato dopo cinque giorni.

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.
