Purpose: Anastomotic leakage (AL) continues to be a challenge after restorative rectal resection (RRR). Various treatment options of AL are available; however, their long-term outcomes are uncertain. We explored the impact of AL on the risk of stoma presence 1 year after RRR for rectal cancer and described treatment of AL after RRR including impact on the probability of receiving adjuvant chemotherapy and stoma presence following different treatment options of AL. Methods: We included 859 patients undergoing RRR in Central Denmark Region between 2013 and 2019. Stoma presence was calculated as the proportion of patients with stoma 1 year after RRR. Multivariable logistic regression was conducted to estimate the impact of AL on stoma presence adjusting for potential predictors. Descriptive data of outcomes were stratified for various treatment options of AL. Results: The risk of stoma presence 1 year after surgery was 9.8% (95% CI 7.98–12.0). Predictors for having stoma 1 year after RRR were AL (OR 8.43 (95% CI 4.87–14.59)) and low tumour height (OR 3.85 (95% CI 1.22–13.21)). For patients eligible for adjuvant chemotherapy, the probability of receiving it was 42.9% (95% CI 21.8–66.0) if treated with endo-SPONGE and 71.4% (95% CI 47.8–88.7) if treated with other anastomosis preserving treatment options. The risk of having stoma 1 year after RRR was 33.9% (95% CI 21.8–47.8) for patients treated with endo-SPONGE and 13.5% (95% CI 5.6–25.8) for patients treated with other anastomosis preserving treatment options (p = 0.013). Conclusion: AL is a strong predictor for stoma presence 1 year after RRR. Patients treated with endo-SPONGE seem to have worse outcomes compared to other anastomosis preserving treatment options.
