Stump Length Is the Most Significant Factor for Rectal Stump Leakage

Rectal stump leakage is a significant complication after discontinuity resection, with a rate of 11.78% in this study. The risk varies depending on the surgical procedure, and it was highest after subtotal pelvic exenteration. Researchers found that a shorter rectal stump, previous pelvic radiotherapy, chemotherapy, and previous laparotomy were independent risk factors for rectal stump leakage. The study highlights the importance of considering these risk factors in surgical decision-making to prevent rectal stump leakage and the subsequent need for invasive treatment and extended hospitalization.
