Background According to previous reports, surgery is not recommended until at least 4 weeks after the symptoms of coronavirus disease 2019 resolve. However, strong evidence has not been established regarding the optimal timing and preoperative examination for elective laparoscopic colectomy for colorectal cancer in individuals with a previous coronavirus disease 2019 infection. Case presentation A 63-year-old Asian man underwent elective laparoscopic colectomy for sigmoid colon cancer 3 weeks after asymptomatic coronavirus disease 2019. The postoperative course was good, and none of the surgical staff was infected with coronavirus disease 2019. Conclusion In this patient infected with coronavirus disease 2019 within 4 weeks of surgery, preoperative venous ultrasound of the lower extremities and a chest computed tomography scan were useful examinations for ensuring a safe surgical procedure for the patient and the staff. Surgery within 4 weeks may be possible with careful selection of cases based on thorough preoperative examination. This report may contribute to the development of a consensus on performing safe elective colectomy for colon cancer in persons previously infected with coronavirus disease 2019.
