“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“

"I usually use the i-scan 1 (SE) at the beginning of all my endoscopic studies. It brings the characteristics of the white light endoscopy with more resolution of the surface which is better to identify lesions. Once I identify a lesion I turn to i-scan 2 (TE) to characterize the vascularity. The new EPK-i7010 with the i-scan OE gives the best features of

mucosal pattern and vascularity with the same tool. In Barrett’s oesophagus the new EPK-i7010 gives the chance to discriminate in the best way the suspicious areas for dysplasia. This allows to take less biopsies in the protocol with better results of getting the dysplastic Barrett’s and identifying the intramucosal neoplasia.“

“i-scan 3 (OE) combines the versatility and flexibility of i-scan with ever sharper and crisper pictures. While i-scan 1 (SE) is my standard setting during every procedure because it gives you the extra bit of contrast and

detail to detect even very subtle changes of the mucosa, i-scan 3 (OE) offers an extremely sharp view of the surface pattern for example in Barrett’s oesophagus. Combine it with the capabilities of the optical

zoom endoscopes and you get the ultimate diagnostic tool in both lower and upper GI tract.”

"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.”

“In the detection and treatment of oesophageal cancers i-scan has transformed the way we can look at our patients. It has helped us to detect early cancers that might not have been possible to see with some of the older generation scopes. In the context of oesophageal cancers which carry a poor prognosis, early detection offers these patients a very realistic chance of curative therapy with either minimally invasive endotherapy or early surgery.”

“The i-scan modes are very helpful in the detection and characterization of Barrett and dysplasia of the stomach.”

”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.”

“I use systematically advanced imaging techniques such as i-scan and i-scan OE in the work-up of patients with suspicion of Barrett’s associated neoplasia to help in the detection of small subtle lesions.“

"In my own practice I rely on i-scan 1 (SE) as my default initial mode for interrogating the upper GI tract. This has superseded the white light mode for me and helps me to assess and detect early cancers. The depth and image resolution is excellent at defining mucosal patterns that when disordered or irregular lead one to suspect neoplasia. My own preference is then to switch to i-scan 2 (TE) to better characterize the lesion in terms of borders but also it allows one to interpret vascularity in great detail. Coupled with the magnification range of endoscopes I have used this mode with much success, for example in patients with early squamous cell cancer of the esophagus. With the combination of conventional chromoendoscopy and agents such as acetic acid it can provide very accurate delineation of flat lesions. Over the past six months I have been using the new optical enhancements that PENTAX Medical have developed beyond the conventional i-scan modes described above. The filtering technology here provides a very distinct and lighter image of the vascularity and mucosal pit patterns that become disordered in early cancer and coupled with i-scan 1 (SE) have in my practice become the two most commonly used enhanced imaging modalities that I use.”

“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.”

“The PENTAX system has made a big difference to the evaluation of Barrett`s patients. We are clearly picking up dysplastic lesions we simply did not see before.”

“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.”

“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.”
