Abstract    Laparoscopic surgery is the main surgical method for rectal cancer, and formulating the appropriate surgical program according to the characteristics of obese patients is still an urgent problem to be solved. When obese patients with rectal cancer undergo laparoscopic surgery, the "patient-centered" Perioperative Surgical Home concept should be implemented. It is necessary to fully understand the unique clinical characteristics of patients, select appropriate intraoperative ventilation strategy and surgical approaches according to their special anatomical structure and physiological characteristics, pay attention to the protection of blood vessels and nerves and ensure the complete resection of tumors, which can improve the surgical treatment effect of obese patients with rectal cancer and reduce the difficulty of surgery. Reduce the occurrence of postoperative complications.
