Abstract: There is increasing evidence that either a transanal stent (TAS) or rectal tube (RT) can decrease the risk of anastomotic leakage (AL) after anterior resection for rectal cancer, in which a diverting stoma may not be required. The aim of this review was to investigate the efficacy and safety of RT/TAS in preventing AL after anterior resections. An up-to-date systematic review was performed on the available literature between 2000 and 2020 on PubMed, EMBASE, Medline and Cochrane Library databases. All studies reporting on anterior resections in adults, comparing transanal tube/stent versus non-tube/stent, were analysed. The primary outcome was rates of AL, whereas secondary outcomes compared associated unplanned re-operation for AL and hospital length of stay (LOS). Two randomized controlled trials and 13 observational studies were included, with 1714 patients receiving RT/TAS and 1741 patients without. There were 119 (7%) patients with AL in the RT/TAS group compared to 216 (12.3%) patients in the non-RT/TAS group (OR: 0.48, 95% CI: 0.38-0.62, p < 0.001). There were 47 (2.9%) patients with AL complications requiring surgery in the RT/TAS group compared to 132 (8%) patients in the non-RT/TAS group (OR: 0.29, 95% CI: 0.20-0.42, p < 0.001) and no significant difference identified with the standardized mean difference (SMD) favouring the RT/TAS group for hospital LOS (SMD: -0.23, 95% CI: -0.51 to 0.06, p = 0.115). The use of RT/TAS post restorative anterior resection for rectal cancer should be considered, given the benefits shown from this meta-analysis.
