The successful intubation of the coecum is one of the main challenges in colonoscopy. Looping of the endoscope could hinder reaching the coecum or even makes it impossible. The 3D navigation system SCOPEPILOT by Pentax allows a real time position monitoring of the endoscope during colonoscopy useing MRI-technology and should facilitate the intubation of the coecum. The aim of this study was to compare the coecal intubation time with SCOPEPILOT versus standard endoscopy. (Source: Gastrointestinal Endoscopy)

Dye-based chromoendoscopy (DBC) is the current gold standard for dysplasia surveillance in Inflammatory Bowel Disease (IBD). However, routine uptake of DBC is limited by its labour intensive nature. Virtual chromoendoscopy may offer a potential alternative. Optical enhancement (OE) is a novel technology that combines the ability to analyze microvascular and pit patterns using band limited light in 2 modes, OE1 and OE2. Enhanced examination of the mucosal pit pattern and surface vessels may increase the ability to detect dysplastic lesions. (Source: Gastrointestinal Endoscopy)

839 significant reduction of post-operative gastroesophageal reflux development by the posterior myotomy using two penetrating vessels (tpvs) in peroral endoscopic myotomy (poem)
Peroral endoscopic myotomy (POEM) is an evolving new treatment strategy for achalasia. To date, a number of studies have demonstrated that POEM can achieve excellent clinical outcomes. However, one of the concerns related to POEM is gastroesophageal reflux (GER) after treatment. The myotomy positions are generally placed at 2 or 5 o ’clock position. Although, the 5 o’clock position (posterior approach) allows better scope maneuverability as the working channel is located over 5-7-o’clock position in most endoscopes, it theoretically has a risk to partially damage oblique muscle, which may increase the fre...

841 is there a difference in outcomes between anterior and posterior peroral endoscopic myotomy (poem)? a randomized study from an experienced high-volume operator
Unlike Laparoscopic myotomy, POEM affords freedom in selecting the myotomy orientation with some centers favoring anterior (A) and some posterior (P) orientation. It has been postulated that posterior POEM by cutting the sling fibers of the LES that maintain the angle of His (rather than the shorter clasp fibers cut in anterior POEM), may result in a more patulous LES with greater relief of dysphagia at the expense of more reflux. Some have also postulated that posterior POEM can be performed more rapidly and easily due to the location of the incision along the axis of the therapeutic channel of the endoscope. (Source: Gas...

For those clinically suspected of having achalasia, esophageal manometry should be performed to establish the diagnosis. High-resolution manometry (HRM) diagnoses achalasia in part upon the presence of incomplete esophagogastric junction (EGJ) relaxation quantified by an elevated median 4 second integrated relaxation pressure (4sIRP). However, determining the 4sIRP can be difficult with nearly 29% of HRM studies limited by an inability to advance the catheter across a non-relaxing EGJ. Endoflip ® impedance planimetry (EIP) is a novel tool to make measurements of the EGJ. (Source: Gastrointestinal Endoscopy)

928 gastric per-oral endoscopic myotomy (g-poem) as a promising therapy for gastroparesis: a meta-analysis
Gastric per-oral endoscopic myotomy (G-POEM) is a newly developed endoscopic technique based on per-oral endoscopic myotomy. It has been applied to the treatment of gastroparesis (diabetic, idiopathic or post-surgery) apart from Gastric Electrical Stimulation (GES) and Laparoscope Pyloromyotomy (LP). However, its role in clinical practice remains controversial and it is not accepted worldwide. We pooled several latest studies and conducted a meta-analysis to explore the efficacy of G-POEM.

929 most advanced endoscopy trainees (aets) meet quality indicator (qi) thresholds in the first year of independent practice: the rapid assessment of trainee endoscopy skills (rates2) study
There are no prospective data on the perceptions, performance and progression of learning curves (LCs) among AETs in the 1st yr of independent practice following an advanced endoscopy training program (AETP). It is unclear whether AETs who complete an AETP with structured feedback achieve established QI benchmarks in the 1st yr of independent practice. (Source: Gastrointestinal Endoscopy)

930 advantage of cap-assisted devices for adenoma detection rate is not enhanced by concomitant use of underwater intubation during colonscopy
Adenoma detection rate (ADR) is inversely related to the risk of interval colorectal cancer and is a primary measure of colonoscopist quality. Multiple studies have shown improved ADR with use of assistive devices, including Endocuff and AmplifEYE. Similarly, use of water exchange or water immersion is associated with improved polyp detection, particularly proximal sessile serrated adenomas, with a trend toward higher detection of adenomas throughout the colon. The potential additive effects of these techniques remain untested. (Source: Gastrointestinal Endoscopy)

931 l-menthol during colonoscopy for adenoma detection in an intermediate risk patient population: a double-blind, randomized controlled trial
Adenoma detection rate (ADR) is defined as the proportion of screening colonoscopies performed by a physician that detect at least one histologically-confirmed colorectal adenoma or adenocarcinoma. Colonoscopy is considered the gold standard for polyp detection and removal. However, there is still a significant number of missed polyps during colonoscopy. (Source: Gastrointestinal Endoscopy)

932 polyps retrieved when trap is attached to instrument port are more frequently intact and interpretable than when removed by conventional method
A major limitation of determination of the completeness of resection in colonoscopy polypectomy is polyp fragmentation. When a polyp fragments, the pathologist cannot determine resection completeness. In current practice, the polyp is retrieved following traversing the entirety of the colonoscope and the specimen negotiates lumen diameter change at the suction valve. Alternative approaches to reduce polyp fragmentation include removal of the suction valve button or alternatively removing polyps through the instrument channel thereby bypassing issues of polyps traversing the suction valve passage entirely.
