398 cuffed colonoscopy with amplifeye improves polyp detection rate - a randomized multicenter study
Colonoscopy screening is proven to reduce mortality rates for colorectal cancer, which relies on early detection and removal of colonic polyps. Methods to improve polyp or adenoma detection have constantly been sought. AmplifEYE is a FDA-approved device with a row of flexible detection arms attached to the tip of colonoscope which can separate colonic folds during scope withdrawal and can improve polyp detection. Clinical data on this relatively new device especially in Chinese patients is lacking. (Source: Gastrointestinal Endoscopy)

399 endoscopic ultrasound guided liver biopsy using a 22 guage fine needle biopsy needle: a prospective study.
Endoscopic ultrasound guided liver biopsy (EUS-LB), is gaining traction as a safe and effective alternative to percutaneous and trans-jugular liver biopsy. EUS guided true-cut and 19-gauge needles can be technically difficult to maneuver, particularly when sampling the right lobe. Other factors that have curtailed the wide spread use of EUS guided liver biopsy are, fear and anxiety about the potential complications with the use of larger bore needles and tissue fragmentation of the histological specimen.

401 duodenal mucosal resurfacing elicits improvement in glycemic and hepatic parameters in type 2 diabetes: complete 1 year results from the first multicenter study
Abnormalities in duodenal mucosa, nutrient absorption and enteroendocrine cell population are thought to play a pathophysiological role in the development of insulin resistance in patients with type 2 diabetes (T2D). Duodenal exclusion via bariatric surgery confers an insulin sensitizing metabolic benefit that is, in part, weight-independent. Duodenal Mucosal Resurfacing (DMR) is an endoscopic procedure that resurfaces the duodenal mucosa through hydrothermal ablation and may confer similar metabolic benefits using a less invasive procedure.

Radiofrequency ablation (RFA) is thoroughly proven to be safe and effective for eradication of Barrett ’s Esophagus (BE) and is therefore the established treatment. However, RFA is associated with significant post-procedural pain. As an alternative, the focal cryoballoon ablation system (CRYO) has recently been developed to apply cryoablation using liquid nitrous oxide. Cryoablation preserves the e xtracellular matrix and might therefore result in less pain, while maintaining sufficient depth of ablation. (Source: Gastrointestinal Endoscopy)

480 safety of the six-shooter multiband mucosectomy device for endoscopic resection in barrett ’s esophagus in 7743 resections: a retrospective international multicenter study.
Endoscopic resection (ER) is an important treatment modality for patients with Barrett ’s esophagus (BE) containing high-grade dysplasia (HGD) or early cancer. The most widely used device for ER is the six-shooter multi-band mucosectomy (MBM) device. This six-shooter consists of a modified variceal band ligator and requires no submucosal lifting or prelooping of a snare in the cap. A randomized study demonstrated that MBM with the six-shooter was equally effective and safe as ER with the classic cap-technique, but significantly faster and cheaper.

While multiple validated risk scores have been developed to assess the severity and need for resource utilization in patients with upper GI bleeding (UGIB), the same has not been true for lower GI bleeding (LGIB). Aoki et al. (2016), developed a recent validated risk scoring system (NOBLADS) exclusively for LGIB. They found that a NOBLADS score ≥ 4 could predict the need for resource utilization overall, as well as the need for any intervention. (Source: Gastro...

542 does initial contrast-enhanced ct impact on clinical outcomes of patients with colon diverticular bleeding?
Although the recommended method of an initial examination of hematochezia is colonoscopy, computed-enhanced CT (CECT) is an appealing diagnostic modality for the same disorder, because it has a superior ability of detecting active bleeding and it is widely available, fast, and minimally invasive. In many centers, CECT has already become an established method for characterizing the location of hematochezia. However, its impact on clinical courses of patients with colon diverticular bleeding is fully known. (Source: Gastrointestinal Endoscopy)

543 relevant factors and significant endoscopic findings for detecting colitis-associated neoplasms using pancolonic narrow band imaging surveillance colonoscopy in patients with ulcerative colitis: a sub-analysis of the navigator study
We recently reported the results of a prospective multicenter randomised controlled trial comparing pancolonic observation using a newly developed narrow band imaging (NBI) (CF-HQ290I) and panchromoendoscopy (PCE) for surveillance colonoscopy in patients with ulcerative colitis (UC). The results revealed that the pancolonic NBI observation was not inferior to PCE for the detection of both neoplastic lesions (13.4% vs 9.0%; P=0.33) and colitis-associated dysplasia or cancer (CC/D) (6.3% vs 4.9%; P=0.86).

544 a randomised crossover trial of conventional versus virtual chromoendoscopy for colitis surveillance: dysplasia detection, feasibility and patient acceptability (convince)
Colitis is associated with an increased lifetime risk of colorectal cancer. Chromoendoscopy (CE) is the current recommended surveillance technique. CE is time-consuming, costly and requires considerable expertise accounting for its limited uptake. Virtual CE (VCE) by Fujinon Intelligent Colour Enhancement ™ digitally reconstructs mucosal images in real-time, without the technical challenges of CE. Furthermore, the current literature provides limited information on patient experience (PE); imperative to adherence to surveillance programmes. (Source: Gastrointestinal Endoscopy)

605 practice patterns and yield of surveillance colonoscopy among older adults: an analysis of the gi quality improvement consortium (giquic)
Currently, there is no guidance around when to stop surveillance colonoscopy in those with a history of adenomas or colorectal cancer (CRC). To define surveillance recommendations, more data on the yield of surveillance colonoscopy by age is needed. We evaluated the yield and practice patterns around surveillance colonoscopy in a large, national clinical data registry, the GI Quality Improvement Consortium (GIQuIC).

607 risks and benefits of colonoscopy in pre-liver transplantation screening
Usually colonoscopy is part of the pre-transplant evaluation in candidates for liver transplantation. Case series suggest that patients with end stage liver disease undergoing colonoscopy are at increased risk for developing complications including bacteraemia, haemodynamic imbalance, and gastro-intestinal bleeding. The aim of the present study was to assess the benefits and risks of colonoscopy in a large cohort of patients evaluated for liver transplantation. (Source: Gastrointestinal Endoscopy)

608 a randomized controlled trial of combined fecal immunochemical test plus sigmoidoscopy based colonoscopy vs. colonoscopy for the detection of advanced neoplasia in the average risk population.
Fecal immunochemical test (FIT) and sigmoidoscopy have been used for colorectal cancer (CRC) screening worldwide. However, the limitations are poorer test sensitivity for advanced neoplasia (AN) and isolated detection in distal colon, respectively. Through this prospective multicenter trial, we compared the detection rate of AN between FIT plus sigmoidoscopy (SIG) based colonoscopy (FITS group) and colonoscopy (COLO group).

609 endocuff assisted colonoscopy significantly improves adenoma detection rate compared to cap assisted colonoscopy: a randomised back to back study (detect)
Adenoma detection rate (ADR) at colonoscopy are directly linked to subsequent risk of post colonoscopy cancer. Common reason for missing adenomas is poor visualisation of proximal folds and flexures during standard colonoscopy (SC). Disposable distal attachments( cap and Endocuff vision) have been reported to improve ADR compared to SC. There are however no comparative randomised trials of these two devices.
