Abstract

Introduction: Presence of intraluminal viable cancer cells implanting into the anastomosis has been proposed as a potential cause for developing local recurrence in patients undergoing anterior resection for rectal cancer. Rectal washout has been proposed as a method to prevent this from happening. There have been conflicting reports in literature regarding the effect of rectal washout on local recurrence. We aim to look at the role of rectal washout in preventing local recurrence of rectal cancer in patients undergoing total or tumor-specific mesorectal excision (TME). Materials and methods: A literature review of studies evaluating the role of rectal washout on rectal cancer local recurrence was performed using PubMed, Scopus, EMBASE and non-English language literature search using CiNii (Japanese) and CNKI (Chinese). Inclusion criteria were use of TME, comparison of rectal washout with no washout, and evaluation of local recurrence as outcome. Results: Four studies were identified according to inclusion criteria. The meta-analysis showed a protective effect of rectal washout on local recurrence (OR 0.45 95% CI 0.45–0.75). However, one of the studies included had more than 90% weightage. Excluding this study from analysis showed no difference on local recurrence with rectal washout (OR 0.94, 95% CI 0.37–2.36). Conclusion: The effect of rectal washout on rectal cancer local recurrence in patients who undergo TME is questionable and needs to be evaluated further by prospective studies.
