“I usually use as default i-scan 1 (SE) as a detection mode and I usually turn on i-scan 3 (OE) when I want to better visualize the mucosal and vascular pattern. I find it particularly useful in Barrett’s oesophagus to diagnose high grade dysplasia area, for rectal and colonic polyp to decide between ESD or piece meal EMR when i-scan 3 (OE) shows aspect of carcinoma in situ or limited to sm1“

“Several studies have shown that digital-based chromoendoscopy is accurate in predicting the histology of polyps of the colon and rectum. The i-scan 1 (SE) is my favorite mode in order to obtain the sharpest image.

In 2013, we observed good interobserver agreement among endoscopists in the evaluation of neoplastic and non-neoplastic lesions visualized with the PENTAX Medical i-scan technique but a poor agreement in the

evaluation of pit-pattern and margins. The recent addition of i-scan 3 (OE) is useful as it really helps me to better assess the vascular and pit patterns of the lesion and accurately identify its margins.”

"I think that i-scan OE represents a further step forward in the diagnostic capabilities of endoscopy. With the i-scan system we can see the mucosa and the lesions with different visualizations that allows to collect different information, specific for each enhance. We can choose the most suitable i-scan function depending on:

anatomical site, pathology or just according to the way the endoscopist feels more confident to be able to make the diagnosis. After my first experience with i-scan OE, I feel that it allows to better study the pit pattern of healthy mucosa and of lesions.

The other 2 important aspects that I want to underline are:

– i-scan 3 (OE) should allow to use the existing classifications already accepted in the literature based on Optical Enhancement making the data resulting from the use of PENTAX Medical endoscopes more comparable.

– i-scan 1 (SE) and i-scan 2 (TE), in addition to the diagnostic capability demonstrated in the literature, allows also to perform an enhanced observation also in difficult conditions like bleeding, bile or fecal residue, when it’s not possible to use an optical system.”

“Accurate interpretation of i-scan images for prediction of hyperplastic and adenomatous colorectal lesions can be learned rapidly.”

“HD i-scan provides the endoscopist with the opportunity to learn about mucosal pit-patterns and, thereby, to understand the biology of GI neoplasms and their clinical significance. It is an outstanding tool for self-learning.”

”The PENTAX Medical High-Definition White Light (HD WL) image is a major advance but when I switch i-scan 1 (SE) on then the image becomes sharper and crisper without losing any other attribute so I don’t see any reason why i-scan 1 (SE) should not be left on at all times. Once I find a subtle abnormality or any obvious lesion then I switch on i-scan 2 (TE) and that really highlights the lesion from the surrounding normal mucosa. Once the presence of neoplasia is confirmed then I switch on i-scan 3 (OE) to fine evaluate the surface and vessel patterns of the lesion (to differentiate neoplastic from non-neoplastic lesion) and identify the exact margins of the lesion. The recent addition of i-scan OE to the PENTAX Medical family has been a major step forward in evaluation and characterization of gastrointestinal neoplasia.”

“In IBD, one can expect also to use the i-scan 3 (OE), especially to predict microscopic inflammation. This concept and assessment is very important for our patients, because mucosal healing is associated with less steroid use, less hospitalization and less surgery for patients. I suspect that the i-scan 3 (OE) technology will be very helpful for the assessment of mucosal healing in patients with inflammatory bowel diseases. In this way, it will help to guide whether medical therapy should be advanced for patients with active mucosal disease or whether medical therapy can be decreased for those who demonstrate good mucosal healing.”

"In order to implement Optical Enhancement (OE) in routine clinical practice, the endoscopist must firstly understand the rationale of this new technology. What is the additional value? HD imaging remains key. Besides this, contrast enhancement using i-scan OE, which is an image pre-processing technology, highlights the epithelial mucosal surface pattern and especially the vascular pattern into detail. i-scan OE facilitates detection and in-vivo diagnosis of lower gastrointestinal tract pathology enabling targeted endotherapy.“

“Since last year we have been using EPK-i7000, which allows you to make a wide range of precise settings for your individual preferences. Moreover this processor gives you all possible options to use i-scan technology of virtual chromoendoscopy at the biggest scale, which makes endoscopy a very creative field of medicine.”

“The i-scan has the potential to facilitate the decision of the nature of the polyp on the spot. i-scan Surface Enhancement is VERY useful.”

“As users of this new technology, we are going through a phase of learning to identify and characterise lesions using i-scan technology developed by PENTAX. This has provided us with a clearer picture of the size and type of lesions seen at endoscopy without using dye-spray.”

“Detection and characterization are important steps during routine endoscopy. First, all suspicious areas have to be identified. Subsequently, the endoscopist has to decide if an endoscopic intervention (e.g. biopsy, endoscopic resection) is needed. The i-scan technology supports both steps and is of great help for everyday endoscopic practice.”

“The i-scan function enhances the mucosal surface and vascular structures that obviate the need for dye spray. The pit patterns and margins of neoplastic lesions can be identified easily to plan treatment or even to take a precise biopsy. I can observe a lot of information on the monitor.”

“The published literature suggests the accuracy rate of white light to be around 60-75%, using PENTAX HD white light we found an accuracy rate of about 90%. It's the first time it has been demonstrated that HD white light alone is very effective. The i-scan further enhanced the accuracy and gave less experienced endoscopists much more confidence in diagnosing.”

“I found that when using i-scan you are more likely, in my opinion, to detect these very small early cancers or small areas of high grade dysplasia or not only that, it's probably easier to demarcate and even classify them in terms of the surface architecture and pit pattern.”

“i-scan is particularly useful for Colitis Surveillance and Barretts Metaplasia.”

“PENTAX i-scan is a great tool for surveillance of colitic patients.”

“i-scan is really useful for characterising dysplasia.”

“I use i-scan routinely for characterisation of all types of pathology.”

“Detection and characterization of pit pattern and vessels - these are the main steps of the diagnostic algorithm in a standard modern endoscopy. Now it is possible to use this logical approach to choose the right therapy plan thanks to the usage of HD+ endoscopy combined with i-scan technology with new options for more detailed examination of mucosa.”
