Status of Colorectal Cancer Devices: Present Scenario

Purpose The purpose of this study was the colonoscopic detection and removal of neoplasia from the colorectum to prevent the development of colorectal cancer. Method Various online medical databases were searched such as PubMed, ACS, NCI, NIH, WHO, etc. for relevant publications and clinical trials for new developments in colonoscopic devices that are intended for diagnostic visualization and therapeutic interventions of the digestive tract. Result HD colon and I-Scan both has shown to increase the detection of sporadic adenomas with high quality. Third Eye Retroscope confers the backward view of colon, but aeroscope screens the entire colon in 30–60 min. Narrow-band imaging enhances mucosal and vascular details through the color differentiation of precancerous or cancerous polyp, compared to white light colonoscopy. The PillCam Colon Capsule is another new technique which is easily inserted and painless. In case of chemotherapy, Therasphere with Yttrium-90 has good results in the treatment of colorectal adenocarcinoma metastasis. Radiofrequency ablation is a good technique for tumors ablation and Staple Line Reinforcement prevents the leak during and post-surgery of colon. FOBT is much more sensitive and cheaper test for colorectal cancer screening. Conclusion Registered clinical trials have shown promising results for neoplasia detection by I-Scan, TER, and NBI imaging techniques will change current colonoscopic practice in colorectal cancer screening. However, more studies and inventions are required for improving the patient safety and efficacy.
