Perioperative management of laparoscopic surgery in a patient with protein S deficiency complications: A case report.

Patients with protein S deficiency are prone to developing thrombosis. During laparoscopic surgery in patients with protein S deficiency, there is a risk of deep venous thromboembolism. In the present case, the patient was a 66-year-old man. He was diagnosed with colon cancer, and surgery was planned. Because of the presence of protein S deficiency, he required careful perioperative management for laparoscopic surgery. Surgery was successfully performed. On postoperative assessment, no thrombi were observed. Our approach of perioperative management might help in the treatment of patients with protein S deficiency.
