Radiation Proctopathy (RP)
RP is a chronic condition that has a significant burden on patients quality of life and healthcare. This clip shows how i-scan 2 helps to highlight the vascular lesions in detail in a patient with symptomatic bleeding and allows targeted YAG laser treatment to the lesions. The vascular areas are not prominent on HD WLE or even i-scan 1 but by switching to i-scan 2 thermal therapy can be directed to the abnormal areas.

Ulcerative colitis
In ulcerative colitis i-scan clearly shows inflammatory changes of the mucosa. We also use it in conjunction with chromoendoscopy for the surveillance of patients with longstanding chronic inflammatory bowel disease to increase detection of flat lesions.

Serrated adenoma
Serrated adenoma are frequently missed as they are flat lesions with very subtle changes to the normal mucosa pattern. i-scan allows for enhanced vision of the vascular pattern and changes like the rim of debris and the mucus cap.

Laterally spreading tumour
In this patient with a laterally spreading tumour granular type i-scan was used to get a clear idea about the polyps pit pattern. As a pit pattern type IV was found, indicating a benign lesion, we proceeded to resect the lesion by means of endoscopic mucosal resection.
