Background and study aims  Treatment of colorectal polyps in patients undergoing permanent anticoagulation is associated with a significantly increased risk of peri-interventional bleeding. This specifically applies to polyps > 1 cm where endoscopic full-thickness resection (EFTR) with the full-thickness-resection device (FTRD) can be taken into consideration as an alternative approach to classical snare polypectomy. For these indications, EFTR appears to be superior to conventional techniques especially in terms of sufficient hemostasis due to the mechanical tissue compression achieved by the FTRD's integrated Over-The-Scope Clip (OTSC)...

BACKGROUND AND STUDY AIMS:  Better patient education prior to colonoscopy improves adherence to instructions for bowel preparation and leads to cleaner colons. We reasoned that computer assisted instruction (CAI) using video and 3 D animations followed by nurse contact maximizes the effectiveness of nurse counselling, increases proportion of clean colons and improves patient experience. PATIENTS AND METHODS:  Adults referred for colonoscopy in a high-volume endoscopy unit in the Netherlands were included...

BACKGROUND AND STUDY AIMS:  Walled-off pancreatic necrosis (WOPN) represents the major risk factor for sepsis-related multiple organ failure. Surgical debridement is an invasive approach associated with high rates of adverse events (AEs) and death. As an alternative, endoscopic ultrasound-guided cysto-gastro-anastomosis has emerged as an effective treatment for WOPNs. Recently a new dedicated-lumen apposing metal stent (LAMS) has been used with satisfactory results in treating peri-pancreatic fluid collections, including WOPNs...

BACKGROUND AND STUDY AIMS : Accurate endoscopic detection of dysplasia in patients with Barrett's esophagus (BE) remains a major clinical challenge. The current standard is to take multiple biopsies under endoscopic image guidance, but this leaves the majority of the tissue unsampled, leading to significant risk of missing dysplasia. Furthermore, determining whether there is submucosal invasion is essential for proper staging. Hence, there is a clinical need for a rapid in vivo wide-field imaging method to identify dysplasia in BE, with the capability of imaging beyond the mucosal layer...

BACKGROUND AND STUDY AIMS:  Recent studies that used magnifying chromoendoscopy and endocytoscopy (EC) to investigate endoscopic features of sessile serrated adenoma/polyps (SSA/Ps) suggested that a dilated crypt opening was an important indicator of SSA/Ps. However, no studies to date have measured the actual extent of dilatation. Hence, we investigated retrospectively the luminal areas using EC to determine a cutoff value for differentiating SSA/Ps from hyperplastic polyps (HPs). PATIENTS AND METHODS : A total of 101 lesions, including 25 SSA/Ps, 66 HPs, and 10 normal mucosal samples, assessed by an integrated-type EC were collected...

BACKGROUND AND STUDY AIMS:  Diagnosis of nonampullary duodenal low grade adenoma (Vienna classification category 3, VCL 3) and high grade adenoma/carcinoma (VCL 4 or higher) is important for clinical management decisions. However, there are no criteria based on which endoscopic diagnosis can differentiate between VCL3 and VCL4 or higher. This study aimed to establish simple diagnostic criteria to differentiate between VCL3 and VCL4 or higher. PATIENTS AND METHODS:  This retrospective study included patients with superficial nonampullary duodenal epithelial tumors (NADETs) who underwent tumor resection between June 2004 and November 2016 at a single cancer center hospital...

BACKGROUND AND AIMS:  Accurate sizing of polyps at time of colonoscopy is critical for determining surveillance intervals. Endoscopists routinely over- or underestimate the size of polyps at colonoscopy. We evaluated the variability in sizing of polyps among multiple endoscopists, and the effect of patient and physician related factors on polyp size estimation in a large community-based practice. METHODS:  Adult patients who underwent a colonoscopy with polypectomy at five endoscopy centers in Minneapolis/St...

BACKGROUND AND STUDY AIMS : Cervical esophageal cancer (CEC) is a less common form of cancer and often locally advanced at the time of diagnosis; thus, survival rates for patients with CEC remain poor. However, no reports exist on results of endoscopic submucosal dissection (ESD) for superficial cancer at the cervical esophagus. The aim of this retrospective study was to elucidate the clinicopathological features and clinical outcomes of ESD for superficial CEC. PATIENTS AND METHODS:  ESD was performed on 891 lesions (in 662 patients) for superficial esophageal cancer from January 2008 to December 2015...

BACKGROUND AND AIMS:  Gastric superficial neoplasia (GSN) is often overlooked at endoscopy because of difficulty in identifying it. The miss rate of GSN at endoscopy and the impact on clinical outcome of the missed GSN have not been fully elucidated. In this study, we investigated these issues. METHODS:  Among 1462 endoscopically and pathologically diagnosed gastric cancers in our hospital from January 2011 to December 2014, previous records of esophagogastroduodenoscopy (EGD) were available for 198 lesions (index lesions) and were reviewed retrospectively...

BACKGROUND AND STUDY AIMS:  Magnifying narrow-band imaging (M-NBI) enables detailed observation of microvascular architecture and can be used in endoscopic diagnosis of colorectal lesion. However, in clinical practice, differential diagnosis and estimation of invasion depth of colorectal lesions based on M-NBI findings require experience. Therefore, developing computer-aided diagnosis (CAD) for M-NBI would be beneficial for clinical practice. The aim of this study was to evaluate the effectiveness of software for CAD of colorectal lesions...

BACKGROUND AND STUDY AIMS : Adenoma detection rate (ADR) is an important measure of colonoscopy quality, as are polyp, advanced ADR, and adenocarcinoma detection rates. We investigated whether performance report cards improved these outcome measures. PATIENTS AND METHODS : Endoscopists were given report cards comparing their detection rates to the institutional mean on an annual basis. Detection rates were evaluated at baseline, 1 year after report cards (Year 1), and 2 years after report cards (Year 2)...
