BACKGROUND Most colonoscopic complications are polypectomy-related and occur more frequently during the removal of numerous small polyps. Therefore, it is important to have the best polypectomy approach of small polyps. The aim of the present animal study was to investigate the effectiveness and safety of cold snare polypectomy (CSP) technique combined with light pull of the snare in order to p...
BACKGROUND Cold polypectomy techniques (without electrocautery) by means of biopsy forceps or snare are widely adopted for the removal of subcentimetric polyps. However, few data are available on the safety of this approach. The aim of this study was to assess the safety of cold polypectomy for subcentimetric polyps, as well as the rate of advanced neoplasia in these lesions. PATIENTS AND MET...
BACKGROUND A use of polypectomy techniques by endoscopist specialty (primary care, surgery, and gastroenterology) and experience (volume), and associations with serious gastrointestinal adverse events, were examined. METHODS A retrospective follow-up study with ambulatory surgery and hospital discharge datasets from Florida, 1999-2001, was used. Thirty-day hospitalizations due to colonic perf...
A 63-year-old man presented to our hospital with chronic abdominal pain associated with intermittent periods of postprandial vomiting. Esophagogastroduodenoscopy and endoscopic ultrasound confirmed the diagnosis of a lipoma in the second portion of the duodenum. Owing to the unavailability of a therapeutic gastroscope, a conventional polypectomy snare was modified (▶Fig. 1) in order to be used ...
