Core tip: This prospective nonrandomized study demonstrates that laparoscopic sphincter-preserving resection for rectal cancer is associated with better preservation of quality of life (QoL) and fewer male sexual problems when compared with open surgery in Chinese patients in the first postoperative year. Our study has several strengths. First, our study only focused on Chinese patients undergoing curative sphincter-preserving rectal resection, thus minimizing the impact of other potential confounders on the QoL assessment. Second, all our questionnaires were administered by a single research assistant and were completed by the patients during clinic visits. Therefore, we achieved 100% compliance at different time points.
