Prophylactic hemoclips in prevention of delayed post-polypectomy bleeding for ??1?cm colorectal polyps: meta-analysis of randomized controlled trials.
Ontology highlight
ABSTRACT: Background and aim? Studies evaluating the role of prophylactic hemoclips (HC) in prevention of delayed post-polypectomy bleeding (DPPB) have reported conflicting results. We conducted a meta-analysis of randomized controlled trials (RCTs) to evaluate the role of prophylactic HC placement in prevention of DPPB for polyps ??1?cm in size. Methods? We reviewed several databases to identify RCTs evaluating the role of HC in prevention of DPPB. The outcomes assessed included prevention of DPPB with polyps 1 to 1.9?cm, ??2?cm, any polyp ??1?cm, proximal colon polyps, distal colon polyps, and perforation. We analyzed data using a fixed effect model and reported summary pooled risk ratios (RR) with 95?% confidence intervals (CI). We assessed heterogeneity with the I 2 statistic. Results? We included nine RCTs with 4550 patients. For polyps ??2?cm, there was a statistically significantly lower risk of DPPB with use of HC; RR 0.55, 95?% CI 0.36, 0.86.?There was also a statistically significantly lower risk for proximal colon polyps ??2 cm; RR 0.41 (0.24, 0.70) but no significant difference for distal polyps; RR 1.23 (0.45, 3.32). There was also no significant difference in risk for polyps 1 to 1.9 cm; RR 1.07 (0.59, 1.97). There was no significant reduction in risk of perforation with HC use for any polyp size. Conclusions? Prophylactic HC placement is effective in prevention of DPPB from proximal colon polyps ??2?cm, but of no significant benefit for polyps 1 to 1.9?cm in size or for distal colon polyps ??2?cm.
