INTRODUCTION: Linked-color imaging (LCI) is a recently developed system used in endoscopy. It creates clear and bright endoscopic images using short-wavelength, narrow-band laser light combined with white laser light. The illuminating light and signal processing emphasize slight color differences in abnormal regions that approximate the normal color of the mucosa. As a result, regions initially appearing red become a deeper shade of red, while regions originally appearing white become brighter, yet with natural tones...

Introduction Colonoscopy trainers have gained recognition for improving endoscopy skills and preparing for real procedures on humans. Unfortunately, due to their high price, commercial simulators are hard to obtain, especially for small medical centers. However, a solution might be to construct a device for themselves. Aim Our goal was to build a relatively cheap and easy-to-construct simulator for residents who want to start learning colonoscopy. Materials and methods The box model colonoscopy trainer was designed and constructed...

BACKGROUND AND AIMS: Large sessile/flat colonic polyps are traditionally removed by lift polypectomy. Underwater endoscopic mucosal resection (UEMR) is a novel technique where air is suctioned out and replaced by water to decompress the colon so that the flat lesions assumes a more polypoid shape facilitating its removal with the standard snare resection. We report the feasibility and safety in our series of patients utilizing this technique. PATIENTS AND METHODS: A retrospective, observational study of all patients who underwent removal of large colonic polyps (>10 mm) over a period of 3 years (January 2012 - January 2015) at a tertiary care center by UEMR were included in the study...

BACKGROUND: /Aims: The United Kingdom (U.K.) guidelines for risk stratification after colon polypectomy differ from the United States (U.S.) guidelines in 2 ways: the U.K. guidelines consider ≥5 adenomas as high risk and do not consider histology (villous or high-grade dysplasia [HGD]) in assessment. Thus, we aimed to investigate the risk of advanced colorectal neoplasm (CRN) by categorized risk groups, considering both ≥5 adenomas and histology. METHODS: A total of 2,570 patients with ≥1 adenoma at index colonoscopy were included...

BACKGROUND: Sessile serrated polyps (SSPs) are associated with higher rates of incomplete resection compared to conventional adenomas after traditional snare polypectomy. Outcomes after endoscopic mucosal resection (EMR) are less established. The aim of this study was to evaluate the rate of residual neoplasia at surveillance colonoscopy for SSPs compared to conventional adenomas ≥ 10 mm after en bloc EMR. METHODS: Retrospective cohort study of consecutive patients referred for EMR of a colonic lesion ≥ 10 mm from 2005 to 2013...

Histological features of colorectal lesions are currently evaluated via a magnifying chromoendoscopy [pit pattern (PIT) classification]. Advanced histological features are rarely observed in diminutive (≤5 mm) adenomatous polyps (DAPs). The Japanese guidelines indicate that diminutive neoplastic lesions without carcinomatous findings may be left untreated and followed up. At the present institution, DAPs with type IIIL PIT are left untreated in various cases, whereas lesions with type III, IV or V PIT are typically resected via routine colonoscopy...

BACKGROUND & AIMS: Inadequate polypectomy leads to incomplete resection, interval colorectal cancer, and adverse events. However, polypectomy competency is rarely reported and quality metrics are lacking. The primary aims of this study were to (1) assess polypectomy competency among a cohort of gastroenterologists, and (2) measure the correlation between polypectomy competency and established colonoscopy quality metrics (adenoma detection rate [ADR] and withdrawal time [WT]). METHODS: We conducted a prospective observational study to assess polypectomy competency amongst 13 high-volume screening colonoscopists at an academic medical center...

REVIEW
Alan Moss, Kumanan Nalankilli
There are several approaches to polypectomy for sessile polyps <20 mm and for pedunculated polyps. Recent evidence is leading towards standardisation of polypectomy technique. Key recent polypectomy developments include: 1. Use of cold snare polypectomy (CSP) for sessile polyps <10 mm; 2. Use of hot snare polypectomy (HSP) following submucosal injection for sessile polyps sized 10-19 mm; 3. Piecemeal cold snare polypectomy (PCSP), with or without prior submucosal injection, for select sessile polyps sized 10-19 mm, where the potential risk for an adverse event is increased (e...

BACKGROUND AND AIMS: Adenoma detection rate (ADR) has been established as a quality indicator for screening colonoscopy. Because ADR is cumbersome to obtain in routine practice, polyp detection rate (PDR), polypectomy rate (PR) and adenoma-to-polyp-detection-rate-ratio (APDRR) have been proposed to estimate ADR. This study aimed to evaluate APDRR in order to estimate ADR (ADRest) in different settings. METHODS: Average risk screening and surveillance colonoscopies from a community-based private practice and a tertiary academic hospital setting were retrospectively evaluated...

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)...

A 78-year-old woman with hypertension had a positive fecal immunochemical test and underwent colonoscopy, which revealed a 4 mm sessile polyp (Paris type; 0-Is) in the transverse colon. Based on low magnification colonoscopy with narrow band imaging, the polyp was Type 2 according to the NBI International Colorectal Endoscopic classification, diagnosed as an adenoma, and then resected via cold snare polypectomy (CSP). Five days after CSP, she complained of right-sided abdominal pain. Abdominal CT showed focal wall thickening of the transverse colon and focal infiltration of tissues surrounding the transverse colon...

Colonoscopy is one of the most commonly performed endoscopic procedures. It is the gold standard examination for work-up of colonic symptoms, for follow-up of positive colorectal cancer screening tests and for detection and removal of neoplastic polyps. Colonoscopy is a complex and invasive procedure with a potential not only for colorectal cancer prevention, but also for serious complications. Numerous factors may affect the balance of benefit versus harm of colonoscopy, including the performance of the endoscopist...

BACKGROUND: Endoscopy has developed rapidly, generating new challenges. Today, there are several procedures done endoscopically with very good results. In the past, the assisted laparoscopic colon polypectomy has been described, reducing the morbidity of a bigger procedure. Nonetheless, little has been said about the use of hybrid surgery in the management of gastric or duodenal polyps. OBJECTIVES: Evaluating the safety and efficacy of the assisted laparoscopic gastric endoscopic polypectomy...
