The effectiveness of rectal washout was compared with no washout for the prevention of local recurrence after anterior rectal resection for rectal cancer.
The following electronic databases were searched: PubMed, OVID Medline, Cochrane Database of Systematic Reviews, EBM Reviews, CINAHL and EMBASE.
Five nonrandomized studies including a total of 5012 patients were identified. Meta-analysis suggested that rectal washout significantly reduced the local recurrence rate (P < 0.0001; OR 0.57; 95% CI 0.43-0.74). It was also significantly lower after washout in patients having radical resection only (P = 0.0004; OR 0.54; 95% CI 0.39-0.76), patients treated by a curative resection (P < 0.0001; OR 0.55; 95% CI 0.42-0.72) and those undergoing preoperative radiotherapy (P = 0.04; OR 0.62; 95% CI 0.39-0.98).
Taking into account the limitations of the design of the included studies the meta-analysis showed that rectal washout is associated with reduced local recurrence and therefore should be routine during anterior resection for rectal cancer.
比较直肠癌前切除术后直肠冲洗与不冲洗对预防局部复发的效果。
检索了以下电子数据库:PubMed、OVID Medline、Cochrane 系统评价数据库、EBM Reviews、CINAHL 和 EMBASE。
共纳入 5 项非随机研究,总计 5012 例患者。Meta 分析表明,直肠冲洗显著降低了局部复发率(P<0.0001;OR 0.57;95%CI 0.43-0.74)。仅行根治性切除术(P=0.0004;OR 0.54;95%CI 0.39-0.76)、根治性切除术(P<0.0001;OR 0.55;95%CI 0.42-0.72)和术前放疗(P=0.04;OR 0.62;95%CI 0.39-0.98)的患者,冲洗后局部复发率也显著降低。
考虑到纳入研究设计的局限性,荟萃分析表明,直肠冲洗与降低局部复发率相关,因此应在直肠癌前切除术常规进行。
