AIM: The effectiveness of rectal washout was compared with no washout for the prevention of local recurrence after anterior rectal resection for rectal cancer. METHOD: The following electronic databases were searched: PubMed, OVID Medline, Cochrane Database of Systematic Reviews, EBM Reviews, CINAHL and EMBASE. RESULTS: 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). CONCLUSION: 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.

Abstract
AIM: The effectiveness of rectal washout was compared with no washout for the prevention of local recurrence after anterior rectal resection for rectal cancer. METHOD: The following electronic databases were searched: PubMed, OVID Medline, Cochrane Database of Systematic Reviews, EBM Reviews, CINAHL and EMBASE. RESULTS: 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). CONCLUSION: 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
