Abstract Objective: To report the feasibility of laparoscopic resection with intraoperative radiotherapy for local advanced rectal cancer in an Asian man. Patient and Methods: A 55-year-old man with adenocarcinoma of the rectum presented at Ruijin Hospital, Shanghai Jiaotong University School of Medicine, Shanghai, China. The tumor, with a size of 5×5 cm, was located 3 cm from the anus and covered a circular area around approximately two-thirds of the bowel. The carcinoembryonic antigen level was 29.86 ng/mL; a nodule was detected, but no distant metastasis was detected. Preoperative staging was T4N1M0. After the patient signed the consent form, laparoscopic resection with intraoperative radiotherapy was performed. Results: The operation time was about 180 minutes, intraoperative blood loss was 100 mL, and postoperative hospital stay was 8 days. The patient had no postoperative complications.
