Core Tip

Core Tip: The current article provides a comprehensive overview of the incidence, risk factors, presentation, evaluation, management and outcomes of patients with rectovaginal fistula resulting from low anterior resection. Notably, the therapeutic options and results are influenced by several factors, including size and location of the fistula, tumor clearance, cancer staging, quality of colorectal anastomosis, surrounding tissue, presence of diverting stoma, previously attempted repair, and the surgeon’s experience. Strategies to prevent rectovaginal fistula formation after rectal cancer surgery are also discussed. A decision-making algorithm for managing this complication is proposed at the end of article.
