Prophylactic hemoclips in prevention of delayed post-polypectomy bleeding for ≥ 1 cm colorectal polyps: meta-analysis of randomized controlled trials.

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.

Project description:BackgroundThe incidence rate of colorectal polyps in children has gradually increased in recent years. It is still unclear whether endoscopic mucosal resection (EMR) can be performed in children with colorectal polyps as well as their incidences of post-polypectomy bleeding and recurrence. This retrospective study was performed to explore the feasible of EMR in children with colorectal polyps and analyze the risk factors of post-polypectomy bleeding and recurrence.MethodsPatients aged younger than 18 years diagnosed with colorectal polyps and received EMR for polypectomy between January 2017 and December 2021 were included in this study. The baseline data of included patients were retrospectively collected. All complications related to polypectomy were recorded during follow up via telephone, internet, or outpatient department, including post-polypectomy bleeding, perforation and polyp recurrence. Patients with and without post-polypectomy complications were divided into 2 groups. The risk factors of post-polypectomy bleeding and polyp recurrence were analyzed using multivariable logistic regression models after adjusting potential risk factors using univariable regression models.ResultsA total of 589 patients were included in this retrospective study. There were 333 male patients and 256 female patients, and their average age was 4.4±1.9 years old. The average diameter of their polyps was 8.4±2.8 mm, and 542 (92.0%) polyps presented as pedunculated lesions. A total of 540 (91.7%) polyps were diagnosed as juvenile polyps and 509 (86.4%) patients had only 1 polyp. There were a total of 75 cases of post-polypectomy complications (12.7%). The most common complication was early post-polypectomy bleeding (5.3%), followed by polyp recurrence (3.7%). Post-polypectomy bleeding occurred the most on the third and fourth day after EMR polypectomy. Larger polyps (OR =1.742, P<0.001), sessile lesions (OR =3.150, P=0.019), and multiple polyps (OR =4.372, P=0.003) were identified to be related to the incidence of post-polypectomy bleeding. Besides, sessile lesions (OR =3.887, P=0.026) were identified as the main risk factor and older patients (OR =0.606, P=0.004) had lower potential for post-polypectomy recurrence.ConclusionsMore attention should be paid to large, sessile, and multiple polyps during the procedure of EMR in children. The small number of patients in this study limits further analysis of results and a large sample study should be performed.
