Task: Question Generation
Input (English): Endoscopic removal of duodenal and colorectal adenomas is currently considered to be the standard of care for prevention of adenocarcinoma. The use of cautery carries a risk of delayed bleeding, post-polypectomy syndrome, and perforation. We examined the safety and feasibility of removing colonic and duodenal polyps ≥\u200a1\u200acm using a piecemeal cold snare polypectomy technique.', 'The study included 15 patients with duodenal polyps ≥\u200a1\u200acm and 15 patients with colonic polyps ≥\u200a1\u200acm.', 'Bleeding, perforation, abdominal pain, or hospitalization occurring within 2 weeks of polypectomy.', 'Between 24 August 2011 and 29 April 2013, 15 patients had removal of duodenal polyps ≥\u200a1\u200acm. Mean patient age was 64 years and 9/15 patients were male. The mean polyp size was 24\u200amm (10\u200a-\u200a60\u200amm). All polyps were removed with a cold snare and some required cold biopsy forceps. One patient required hospitalization for gastrointestinal blood loss 7 days post-polypectomy; this patient was using Coumadin. Between 27 February 2012 and 30 May 2013, 15 patients underwent resection of a ≥\u200a1\u200acm colonic polyp.\u200aMean patient age was 68 years and 9/15 were male. The mean polyp size was 20\u200amm (10\u200a-\u200a45\u200amm). All polyps were primarily removed with a cold snare. None of the patients required hemostatic clips for control of immediate bleeding. One patient presented to the emergency department with abdominal pain 1 day after initial endoscopy. CT scan showed no abnormalities and the patient was discharged.
Output (English): Do cold snare piecemeal resection of colonic and duodenal polyps ≥1 cm?
