The future of wireless capsule endoscopy
The capsule endoscopy will become increasingly effective in diagnostic gastrointestinal endoscopy. a higher take up rate is expected for this technlogy because it is painless and the major share is to be ised for the cancer and varices detection. The Barrett’s and esophageal varices have been imaged using this technology but the image quality of the technology still needs improvement as the image quality is not as par with the conventional upper and lower gastrointestinal endoscopy. The parameters such as the angle of view, depth of field, image numbers, frame rate, etc needs to be subjected to improvements. The Colonic, esophageal and gastric capsules will come to the improvement of the image quality and it is expected that slowly the supremacy of the flexible endoscopy is eroded. Teh features such as brushing, cytology, fluid aspiration, biopsy and drug delivery capabilities are the added attractive features that may coem with the capsukle endoscopy. These devices will brign about a combination of physiological measurements with imaging and optical biopsy.
