Abstract: Objective: The objective of this systematic review was to conduct a more comprehensive literature search and meta-analysis of original studies to evaluate the efficacy and safety of the loop electrosurgical excision procedure (LEEP) versus cold-knife conization (CKC) in conservative surgical treatment of cervical adenocarcinoma in situ (ACIS) for women who have not completed childbearing. Methods: Systematic searches were conducted in the PUBMED, EMBASE, Cochrane, and China National Knowledge Infrastructure (CNKI) databases to identify all potential studies involving patients with ACIS treated with LEEP versus CKC published until December 2015. Results: Eighteen retrospective studies were included in this systematic review. All the 18 included studies reported the rate of positive margins, and the results of the individual studies varied. The positive margins were 44% (267/607) after LEEP and 29% (274/952) after CKC. The pooled meta-analysis exhibited significantly different outcome (RR, 1.55; 95% CI, 1.34–1.80, P
