| [ Summary ] |
A systematic review concerning complications from colorectal hot forceps polypectomies (HFP), hot snare polypectomies (HSP) and endoscopic mucosal resection (EMR) was conducted. The respective rates of postprocedural bleeding (PPB) for HFP, HSP, EMR were 0.29-0.38 %, 0.92-1.5 % and 1.02-1.4 %. However, rates were higher in larger lesions ; 1.96-11 % in those >20 mm. The respective rates of perforation for HFP, HSP, EMR were 0.01-0.05 %, 0.02-0.05 %, 0.09-0.63 % and the rates were no higher than 1 % even in >20 mm lesions. Intraprocedural bleeding (IPB) can occur at rates as high as 1.77-9.13 % for cold snare polypectomies (CSP). On the other hand, rates of PPB for CSP were only 0-0.3 % ; lower than for other resection methods with coagulation. Rates of perforation were almost zero for CSP. When reviewing the literature attention should be payed to the following points ; if the study was prospective or retrospective, the average size of target lesions, the definition of complication(s) and if the rates were calculated per patient or per lesion. |
