Prophylactic clip closure reduced the risk of delayed postpolypectomy hemorrhage: experience in 277 clipped large sessile or flat colorectal lesions and 247 control lesions
چکیده انگلیسی

BackgroundEndoscopic resection of large colorectal lesions is associated with high complication rates.ObjectiveTo evaluate the effect of prophylactic clip closure of polypectomy sites after resection of large (≥2 cm) sessile and flat colorectal lesions.DesignRetrospective study.SettingTertiary referral center.Patients and InterventionsPatients with lesions 2 cm or larger who underwent EMR performed by using low-power coagulation current between January 2000 and February 2012. Beginning in June 2006, polypectomy sites were prophylactically closed with clips when possible. Patients had telephone follow-up at 30 days or later to track complications.Main Outcome MeasurementsDelayed hemorrhage, postpolypectomy syndrome, and perforation.ResultsThere were 524 lesions 2 cm or larger in 463 patients, of which 247 (47.1%) were not clipped, 52 (9.9%) were partially clipped, and 225 (42.9%) were fully clipped. There were 31 delayed hemorrhages, 2 perforations, and 6 cases of postpolypectomy syndrome. The delayed hemorrhage rate was 9.7% in the not clipped group versus 1.8% in the fully clipped group. Multivariate analysis showed that not clipping (odds ratio [OR] 6.0; 95% CI, 2.0-18.5), location proximal to the splenic flexure (OR 2.9; 95% CI, 1.05-8.1), and polyp size (OR 1.3; 95% CI, 1.1-1.7 for each 10-mm increase in size) were associated with delayed bleeding.LimitationRetrospective design.ConclusionsProphylactic clipping of resection sites after endoscopic removal of large (≥2 cm) colorectal lesions using low-power coagulation current reduced the risk of delayed postpolypectomy hemorrhage. A randomized, prospective trial of clipping large polypectomy sites is warranted.
