This study aimed to evaluate the efficacy and safety of the two approaches.  \nMethods We systematically retrieved literature from January 1, 2000, to May 30, 2023, from the PubMed, Embase, Web of Science, SinoMed, Wanfang Data, Chinese National Knowledge Infrastructure, and Cochrane Central Register of Clinical Trials databases. Randomized controlled trials (RCTs) or cohort studies of SEMS versus DT as BTS in colorec‑ tal cancer obstruction were selected. Risks of bias were assessed for RCTs and cohort studies using the Cochrane Risk of Bias tool version 2 and Risk of Bias in Nonrandomized Studies of Interventions. Certainty of evidence was deter‑ mined using the Graded Recommendation Assessment. Odds ratio (OR), mean difference (MD), and 95% confidence interval (95% CI) were used to analyze measurement data.  \nResults We included eight RCTs and eighteen cohort studies involving 2,061 patients (SEMS, 1,044; DT, 1,017) .  \nPooled RCT and cohort data indicated the SEMS group had a significantly higher clinical success rate than the DT group (OR = 1 . 99, 95% CI 1. 04, 3 . 81, P = 0 . 04), but no significant difference regarding technical success (OR = 1 . 29, 95% CI 0. 56, 2 . 96, P = 0 . 55) . SEMS had a shorter postoperative length of hospital stays (MD = − 4 .47, 95% CI − 6 . 26, − 2 . 69, P \u003C 0. 00001), a lower rates of operation‑related abdominal pain (OR = 0 . 16, 95% CI 0. 05, 0 . 50, P = 0 . 002), intraopera‑ tive bleeding (MD = − 37 . 67, 95% CI − 62 . 73, − 12. 60, P = 0 . 003), stoma creation (OR = 0 .41, 95% CI 0. 23, 0 . 73, P = 0 . 002) and long‑term tumor recurrence rate than DT (OR = 0 .47, 95% CI 0. 22, 0 . 99, P = 0 . 05) .  \nConclusion SEMS and DT are both safe as BTS to avoid emergency surgery for patients with colorectal cancer obstruction. SEMS is preferable because of higher clinical success rates, lower rates of operation‑related abdominal  \n†Wei Mai and Jian‑Cheng Zhang contributed equally to this work.  \n*Correspondence: Bin Cai[cdjianghua@qq.com](cdjianghua@qq.com)[ ](cdjianghua@qq.com)Hua Jiang [jianghua@uestc.edu.cn](jianghua@uestc.edu.cn)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2023.
