Although lateral pelvic lymph node dissection (LLND) might be an effective procedure for such patients, the associated risk factors for postoperative complications are unknown. Patients and Methods: The operative outcomes of 21 patients undergoing unilateral LLND and 26 patients undergoing bilateral LLND for rectal cancer were compared. The risk factors for complications were evaluated using a logistic regression model. Results: Univariate and multivariate analyses revealed that a longer operative time (≥480 min) was the most important risk factor for grade II or more postoperative complications according to the Clavien–Dindo classification (odds ratio=6.58; 95% confidence interval=1.35-32.1; p=0.020). A bilateral procedure was not a significant risk factor for postoperative complications. Conclusion: Surgeons should make efforts to shorten the operative time to reduce the risk of postoperative complications. ER -
