Background and study aims Cold snare polypectomy is an established method for the resection of small colorectal polyps; however, significant incomplete resection rates still leave room for improvement. We aimed to assess the efficacy of cold snare endoscopic mucosal resection (CS-EMR), compared with hot snare endoscopic mucosal resection (HS-EMR), for nonpedunculated polyps sized 6 - 10 mm. Patients and methods This study was a dual-center, randomized, noninferiority trial. Consecutive adult patients with at least one nonpedunculated polyp sized 6 - 10 mm were enrolled...

The majority of foreign bodies ingested pass uneventfully through the gastrointestinal tract without endoscopic intervention. Nevertheless, certain ingested objects pose a greater risk for complications and are more challenging to remove than others. This case report describes a 49-year-old male who swallowed a cigarette lighter causing a gastric ulcer. The lighter was successfully removed by flexible endoscopy using a polypectomy snare. Urgent removal is required due to the shape of the object and its hazardous contents...

BACKGROUND: Endoscopic mucosal resection (EMR) has been proven to be safe and effective for the treatment of colorectal adenomas. However, data are limited on the safety of this technique for large polyps and in elderly patients. Aims of our study were to examine the bleeding and perforation rates in patients with large non-pedunculated adenomas (≥20mm) and to evaluate the influence of size (≥40mm) and age (≥75 years) on the complication rates. METHODS: In this multicenter retrospective study, patients who underwent EMR of non-pedunculated adenomas ≥20mm between January 2012 and March 2016 were included...

A 77-year-old man was admitted with posterior cervical pain, lumbago, a low-grade fever, and anorexia after bowel cleaning with polyethylene glycol for colonoscopy. Computed tomography of the neck showed calcification of the transverse ligament of the atlas. He was diagnosed with crowned dens syndrome (CDS). His condition improved following treatment with corticosteroids. This represents a rare case of CDS after endoscopy with polypectomy. We should consider CDS in the differential diagnosis of patients with unexplained fever and posterior cervical pain after bowel preparation for 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...

INTRODUCTION: Duodenal polyps and especially duodenal adenomas are a rare and mostly coincidental finding in patients undergoing upper gastrointestinal endoscopy. Due to their malignant potential, duodenal adenomas should be removed upon diagnosis. So far, the limited available data on the performance of endoscopic polypectomy show conflicting results with regard to adverse events and the adenoma recurrence rate. PATIENTS AND METHODS: After summarizing the currently available data, we retrospectively analyzed all patients undergoing endoscopic resection of nonampullary duodenal adenomas (NAD) at our institution between 2006 and 2016...

BACKGROUND: Currently, colonoscopy and polypectomy are the gold standard methods for the prevention of incident cases of colorectal cancer. The use of a new colonoscope (Fuse(®), EndoChoice(®)) with a larger view of up to 330° appears to improve the adenoma detection rate (ADR). We performed a prospective observational study concerning this scope. The primary endpoint was potentially omitted adenomas (POA), i.e. adenomas seen on the side screens that will not appear on the central display during colonoscopy withdrawal without oriented movements...

Resectoscopic surgery is routinely performed to remove endometrial polyps and uterine myomas. A search of MEDLINE, PubMed and the Cochrane library was conducted through November 2016, for studies written in English, regardless of sample size or study type. The studies were then filtered by selecting those evaluating resectoscopic surgery. The analysis of peer-reviewed, published literature was performed to examine the clinical application of this treatment modality on patients requiring polypectomy and myomectomy...

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...

Most colorectal cancers evolve from colorectal adenomatous polyps in a pathway known as the adenoma to carcinoma sequence. Early detection and removal of colorectal adenomas can prevent the development of colorectal cancer. The vast majority of these polyps can be resected endoscopically. Advances in endoscopic resection techniques have led to expanded indications for endoscopic polypectomy, whereby giant polyps, scarred lesions and early cancers may be cured. We will outline conventional endoscopic mucosal resection techniques as well as more complex resection methods such as endoscopic submucosal dissection, full thickness resection and the use of combined endoscopic and laparoscopic assisted approaches to resection...

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: Although cold polypectomy techniques are preferred over polypectomy with electrocautery in the management of diminutive polyps, comprehensive comparisons among various cold polypectomy techniques have not yet been fully performed. METHODS: We searched for all relevant randomized controlled trials published up until October 2016 examining the efficacy of cold polypectomy techniques for diminutive polyps. Cold polypectomy techniques were classified as cold forceps polypectomy (CFP), jumbo forceps polypectomy (JFP), traditional cold snare polypectomy (CSP), and dedicated CSP, according to the type of device...

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)...

STUDY OBJECTIVE: The standard treatment of endometrial cancer (EC) and complex atypical hyperplasia (CAH) is hysterectomy with or without adnexectomy. In the last decade, several centers have attempted to perform hysteroscopic resection of malignant and pre-malignant polyps as an alternative to hysterectomy. In the present study, we evaluated the safety of this procedure in regard to residual uterine pathology. DESIGN: Retrospective chart review DESIGN CLASSIFICATION: Canadian Task Force classification II-2 SETTING: University hospital PATIENTS: 1766 women who underwent hysteroscopic polypectomy during the years 1998-2016 MEASUREMENTS: Patients with CAH and endometrioid type EC in the removed polyps who underwent hysterectomy were included in the study...

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...
