Objects
To study risk factors for low colorectal anastomotic leak after pelvic exenteration for gynecologic malignancies.

Methods
Data from 60 patients, 32 with ovarian cancer and 28 with nonovarian cancer who underwent pelvic exenteration with colorectal anastomosis (CRA) were retrospectively analyzed.

Results
Overall rate of CRA leak was 20%. The CRA leak was associated with type of tumor (3% for the ovarian cancer and 40.8% for the nonovarian cancer, P = 0.004), CRA height (<5 cm vs ≥5 cm, 75% vs 6.3%; P = 0.001), and previous radiotherapy (RT; 53.3% vs 8.9%; P = 0.001). Multivariate analysis showed that only previous RT and CRA height were associated with the CRA leak. Rectosigmoid wall involvement (81.8% vs 27%; P = 0.001) and mesorectum infiltration (69.2% vs 21.7%; P = 0.001) were more frequent among patients with ovarian cancer patients.

Conclusions
Previous RT and CRA at or less than 5 cm from the anal verge pose a high risk for CRA leak. In these cases, a definitive colostomy should be recommended.
