SEMINAR ON PILL CAM
[attachment=47623]
ABSTRACT
Endoscopy is a minimally invasive diagnostic medical procedure used to assess the interior surfaces of an organ by inserting a tiny tube into the body, often, but not necessarily, through a natural body opening. Through the scope one is able to see lesions and other surface conditions
This paper mainly projects the applications and advantages of the PillCam that has brought a revolution in the field of endoscopy
The PillCam capsules are miniaturized disposable color video cameras encased in a plastic shell, which incorporate one or more specially developed imaging devices based on complementary metal oxide semiconductors_(CMOS)_technology. About the size of a large vitamin, the capsule is made of specially sealed biocompatible material that is resistant to stomach acid and powerful digestive enzymes.
Another name for this new technique is Wireless Capsule Endoscopy .
It is expected that the discussion of these key items provides a view towards the future of endoscopy.
Major advances in endoscopic technology have occurred over the past 30 years—advances that have transformed the field from one of purely diagnostic applications to one including therapeutic applications. Technological innovations will facilitate advances in our ability to perform minimally invasive endoscopic surgery, optimize patient comfort during procedures, and ultimately lead to improved outcomes in patients with gastrointestinal disorders.
Introduction
Endoscopy is a diagnostic medical procedure used to assess the interior surfaces of an organ by inserting a tiny tube into the body, often, but not necessarily, through a natural body aperture..Through the endoscope lesions and other surface conditions can be observed.
The instrument may have a rigid or a flexible tube that not only provides an image for visual inspection and photography , but also enables in making biopsies and retrieval of foreign objects from the body. Endoscopy is the vehicle for minimally invasive surgery .
Many endoscopic procedures are relatively painless and, at worst, associated with mild discomfort, even though patients are sedated for most procedures. Complications are rare (only 5% of all operations) but can include perforation of the organ under inspection with the endoscope or biopsy instrument. If that occurs open surgery may be required to repair the injury.
Earlier Method
Earlier methods used a fibre which was inserted and helped in transmitting the pictures of the digestive track.
The following figure shows a typical Endoscope
End oscopes consist of three tubes; a light emitting fibre, a fibre which transmits the image to the physician and tube which can be used for the administration of drugs as well as having the ability to hold a brush or incisor instrument for the removal of damaged body tissue or for taking tissue samples.
In the earlier endoscopy methods, a half inch diameter tube is sent inside the body through throat. If there is any difficulty with the patient in swallowing the tube, his/her throat is sprayed with a sedative whichsedative, which makes the job easier and less painful.
Revolution in Endoscopy
In 1981, an Israeli physician, Dr. Gavriel Iddan, began development of a video camera that would fit inside a pill. Technology was not ready and the idea was put on hold. It took 20 years for technology to catch up with Dr. Iddan. In 2001, the FDA approved the Given Diagnostic Imaging System . This may sound like science fiction, but this 11 x 26 mm capsule weighs only 4 gms (about 1/7 th of an ounce) and contains a color video camera and wireless radiofrequency transmitter, 4 LED lights, and enough battery power to take 50,000 color images during an 8-hour journey through the digestive tract. About the size of a large vitamin, the capsule is made of specially sealed biocompatible material that is resistant to stomach acid and powerful digestive enzymes.
Conclusion
It is hoped that this discussion of these key presentations provides a view toward the future of endoscopy. Major advances in endoscopic technology have occurred over the past 30 years—advances that have transformed the field from one of purely diagnostic applications to one including therapeutic applications. Technologic innovations will facilitate advances in our ability to perform minimally invasive endoscopic surgery, optimize patient comfort during procedures, and ultimately lead to improved outcomes in patients with gastrointestinal disorders.
