Abstract:

Colorectal cancer is a malignancy with high incidence, and its incidence increases with age. Each year 50% of new colorectal cancer patients are over 70 years old worldwide, and 25% of new colorectal cancer patients are over 80 years old. Preoperatively, elderly patients are more likely to have complications and thus have a higher perioperative risk. In addition, elderly patients are often accompanied with more advanced local tumor lesions, which frequently caused intestinal obstruction or lesion metastasis at the time of consultation, resulting in more difficult surgeries. It has been established that advanced age is an independent risk factor for increased perioperative mortality and mobility. Therefore, in order to cope better with the challenges of perioperative management of elderly colorectal cancer patients, this expert consensus on perioperative management of elderly patients with colorectal cancer is developed by the experts of the Perioperative Medicine Special Committee of the Chinese Society of Colorectal Cancer. And this expert consensus included preoperative, intraoperative and postoperative stages of perioperative periods. And comprehensive preoperative evaluations in elderly colorectal cancer patients, rehabilitation measures, lung protective ventilation strategy, goal-directed fluid therapy, regional analgesia management and prevention and treatment of postoperative cognitive dysfunction are all discussed in this expert consensus. Therefore, this expert consensus further improves the perioperative management level of elderly colorectal cancer patients, speeds up postoperative rehabilitation and improves the prognosis of elderly colorectal cancer patients.
