Classic and Capsule Endoscopy
EXPLORATION OF THE DIGESTIVE TUBE WITH VIDEO CAPSULE ENDOSCOPY
Academica Medical Centre provides you with one of the most advanced investigation methods of the digestive tube: VIDEO CAPSULE ENDOSCOPY.
The video capsule endoscopy is a long-awaited discovery which truly revolutionizes this exploration field.
The video capsule is a miniature single-use photo camera, created to offer images of the lumen of the digestive tube.
The video capsule can be used to explore the small bowel or colon.
If classic endoscopy offers the possibility to visualize the mucous of the esophagus and stomach (upper digestive endoscopy) and colon and terminal area of the bowel (colonoscopy and rectoscopy), respectively, the territory of the small bowel, with a considerable length and a diameter small enough, until recently was a "white spot" on the visualization map of the digestive tube.
The video capsule for the small bowel is able to highlight images that lead to the provision of diagnosis in delicate pathologies, such as unexplained digestive bleeding, intestinal polyposis (familial many times), Crohn"™s disease, tumors of the small bowel, various plane lesions of the mucous, but also to the monitoring of lesions caused by long-term anti-inflammatory treatment.
The colon video capsule can highlight early stage colon tumors, as well as other problems, such as ulcerative colitis lesions.
The video capsule is provided with a system to capture the images (2 "“ 4/second) and records lesions of a tenth of a millimeter. In addition to the photo camera, it also has a light source (flash), two batteries, an emitter and an antenna. The equipment is made of eight electrodes, a small portable recorder and a computer with special software.
The captured images are transmitted continuously to a device named receiver which the patient is carrying until the release of the capsule. The data are transmitted then from the receiver to a computer where they are analyzed by specialists, confronting them with images from a wide image data base.
The video capsule is disposable, has an energetic independence of up to 10 hours and is released naturally through the digestive tube.
As it is approximately of the size of an antibiotic - 11 mm/27 mm and weighs 4 grams) "“ the video capsule is swallowed with water and without food (2 hours before and 4 hours after ingestion).
The diagnosis capability is twice as high as the other types of classic radiologic explorations of the digestive tube.
The advantages of the video capsule compared to the classic endoscopic methods are:
- easy ingestion because it has the size of a usual antibiotic tablet
- does not require anesthesia
- allows the investigation of a portion of the digestive tube which is accessible through classic methods (small bowel)
- it is easy to accept, because it does not imply the discomfort of the invasive colonoscopic examinations
- it is released after 24 - 48 hours
- high quality and resolution of the images
In order to validate the requirement for this investigation, a specialty medical consultation is mandatory before the beginning of the endoscopic procedure.
Many times, through the diagnosis performed with video capsule endoscopy, we can avoid too many expensive and difficult explorations and we can gain valuable time by being able to start an early treatment, which sometimes can save lives.
At Academica Medical Centre the upper and lower digestive endoscopies are performed with state-of-the-art equipment from Olympus, worldwide leader in manufacturing this type of devices. This generation of Olympus digestive endoscopes has a unique clarity of the images, allowing an accurate diagnosis under fast and safe investigations.
Upper digestive endoscopy is an investigation procedure which allows the doctor to explore the esophagus, stomach and first part of the small bowel (duodenum) by means of a slim and flexible instrument, provided with an optic device, which is named endoscope. This type of endoscope is inserted through the oral cavity and is easily advanced through the throat, until it reaches the esophagus, stomach and then the duodenum. This investigation is sometimes named esophagogastroduoedenoscopy because the entire upper digestive tract is examined through it. By means of endoscopy, the doctor can see ulcerations, inflammations, tumors, infections or bleeding within the upper digestive tract. Tissue can be collected (biopsy), polyps can be removed and bleeding can be treated within this part of the digestive tube. Endoscopy can reveal problems which are not discovered by means of radiology and can sometimes help in avoiding the requirement for an exploratory surgical intervention.
Lower digestive endoscopy (colonoscopy, rectosigmoidoscopy, anuscopy) is the examination of the large bowel with the endoscope which captures images inside the bowel and shows them on a screen. By means of the endoscope we can see abnormalities or lesions inside the colon (getting additional information compared to the use of the radiologic technique (irrigography). Also, during the colonoscopy biopsies can be collected from the shown lesions so as the sick tissue can be examined with a microscope.
