Colonoscopy with one detected polyp in the transverse colon

The video shows 49 year old male with suspected food allergy. During colonoscopy, one polyp in the transverse colon was detected. The histology showed a lymphoid follicle and tubular adenoma with LGIEN.
Two aspects in the lesion, the central pit pattern is almost invisible under white light endoscopy and comes out much clearer under i-scan 1 (surface enhancement for detection) and i-scan 2 (tone enhancement for characterization).

Colonoscopy with two detected polyps

The video shows a colonoscopy of a 31 year old male with suspected food allergy. During the colonoscopy two polyps were found:
- one tubular adenoma with LGIEN in the descending colon 
- one tubular adenoma with LGIEN in the sigmoid colon
The lesion can be easily missed with white light endoscopy (WLE), also in the setting of a very young patient. 
By using i-scan 1, a better demarcation is possible. The vascular pattern are almost invisible unless i-scan OE is used.

Colonoscopy with detected Tubular Adenoma with LGIEN and SSA polyps

The video shows a screening colonoscopy of a 71 year old female. Two polyps were found during the screening: 
- one tubular adenoma in the cecum 
- one sessile serrated Adenoma (SSA) in the ascending colon. The pit pattern of polyp number two is almost not visible under white light endoscopy but comes out with i-scan (Type II open). Since SSA show accelerated progression towards CRC, i-scan really helps to differentiate them from hyperplastic lesions.

Normal duodenal architecture

This sequence demonstrates the normal villous architecture of the second part of the duodenum in detail using PENTAX HD+ with i-scan enhancement.

Crohn`s disease duodenum

Crohn’s disease of the upper GI tract is rare and lesions can easily be missed as they are small. i-scan highlights inflammatory changes of the duodenal mucosa and enhances contrast thus making detection of small aphthoid lesions easier.

Gastric cancer

This video sequence demonstrates to observe characteristic of surface pattern with i-scan SE then switch to i-scan OE to observe vessel pattern. i-scan OE brought up better assessment of vessel as compared with chromo endoscopy. Following pathological result concluded mucosal cancer 8mm in size.

Gastric cancer

This video sequence demonstrates to observe characteristic of surface pattern with i-scan SE then switch to i-scan OE to observe vessel pattern and demarcation line of lesion without help of magnified scopes. Following pathological result concluded gastric cancer invaded slightly the submucosa.

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.

Early gastric cancer

In this video clip i-scan is used to both detect a lesion and to get a clear idea of its margins. Based on i-scan and additional staining with indigo carmine the lesion`s margins were marked and an endoscopic submucosal dissection performed.

Hyperplastic gastric polyp

This patient presented with anaemia.

At endoscopy the patient was found to have a large hyperplastic polyp in the stomach. This video sequence demonstrates the characteristic PIT pattern of the hyperplastic lesion using PENTAX HD+ and i-scan enhancement.

This image enhancement was used to direct YAG laser therapy to this area to prevent further blood loss.

Gastric high grade dysplasia

This patient was followed up for a gastric ulcer that had caused a large upper GI bleed. At endoscopy there is a dysplastic antral lesion seen on Pentax enhanced imaging. This lesion was removed by Endoscopic Submucosal Resection.

Crohn`s disease ileum

Aphthoid ulcers of the terminal ileum are a typical finding in Crohn’s disease. As seen in this video, contrast and tone enhancement makes even subtle changes easier to spot.

Squamous dysplasia of the oesophagus

Early squamous neoplasia is a very aggressive pathology and the decision when to choose oesophageal sparing local endoscopic resective therapy, over invasive interventions such as surgery, depends on accurate staging. Micro-vasculature in squamous dysplasia is key to informing the endoscopist on the potential depth of invasion. Intrapapillary capillary loops arise from the submucosal veins. This short video clip shows an abnormal area with squamous dysplasia that with the magniview scope and i-scan 2 has type II IPCSLs. The normal vasculature is shown before the abnormal vessels come in to view with zoom imaging. This area was resected by EMR and show M3 invasion alone.

Squamous cell cancer of the oesophagus

Early squamous cell cancer of the oesophagus is easily missed. In these flat lesions, it is also difficult to identify the margins of the tumor. In this patient i-scan was used to assess the extension of the mucosal cancer before performing endoscopic submucosal dissection.

Early squamous neoplasia of the oesophagus (sq emr)

Early squamous neoplasia of the oesophagus is often very difficult to appreciate with white light endoscopy alone. This patient was referred for assessment of acid reflux symptoms and the referring centre had taken random oesophageal biopsies which reported features consistent with atypia. With enhanced imaging and i-scan, there is an extensive circumferential lesion with abnormal vasculature and mucosal irregularity. With lugol’s chromoendoscopy the extent of the lesion is further appreciated with extensive areas of oesophageal unstaining.

A rare case of malignant melanoma of the oesophagus (Melanoma)

The clip shows a very interesting appearance of the oesophagus. With the various enhancement settings and i-scan, one can see multiple pigmented plaques throughout the tubular oesophagus with areas of hyper-vascularity and dilated tortuous micro-vasculature on i-scan 2. This patient has malignant melanoma of the oesophagus and went on to have an oesophagectomy.

Early oesophageal neoplasia arising in a patient with Barrett`s oesophagus (ACA EMR)

This is a recording of a patient with early Barrett’s cancer. They were referred for radiofrequency ablation. With enhanced imaging and i-scan 1 there is a very subtle nodule with an area of irregularity at the centre.
