Chromoendoscopy with Targeted Biopsy to Detect Nonpolypoid Colorectal Neoplasms

Video Transcription

Video Summary

The video discusses the use of chromoendoscopy with targeted biopsy to detect nonpolypoid colorectal neoplasms in patients with inflammatory bowel disease (IBD). It emphasizes that IBD patients have an increased risk of colorectal cancer and that the current standard of random biopsies for surveillance of dysplasia in IBD patients is inadequate. Chromoendoscopy with indigo carmine is recommended by various gastroenterological societies as it increases the likelihood of detecting dysplasia compared to white light endoscopy. The video provides examples of various cases where chromoendoscopy helped identify and assess dysplastic lesions. It also explains the technique of chromoendoscopy, including the preparation of the dye solution and the targeted biopsies. The video concludes by stating that chromoendoscopy with targeted biopsy is crucial for detecting and diagnosing dysplasia in the colon of IBD patients and should not be replaced by high definition or other equipment-based image-enhanced endoscopy techniques. The use of indigo carmine is recommended over methylene blue due to potential safety concerns.
