Risk Factors for Rectal Stump Leakage After Discontinuity Resection: Stump Length Matters Most.

Background: Discontinuity resection is commonly conducted to avoid anastomotic leakage in high-risk patients but potentially results in rectal stump leakage. Although risk factors for anastomotic leakage have been widely studied, data on rectal stump leakage rates and underlying risk factors are scarce.

Objective: To determine rectal stump leakage rates following Hartmann's procedure and to identify patient-and surgery-associated risk factors.
