Effects of Incomplete ERAS on Clinical Outcomes in Patients With Colorectal Cancer

Effects of Incomplete Enhanced Recovery After Surgery Program on Long-term Survival of Patients Undergoing Colorectal Cancer Surgery

Enhanced recovery after surgery (ERAS) has been reported to be associated with improved outcomes in many studies, most of which involve short-term effects. Only a few studies have reported the long-term effects of highly compliant ERAS. However, to the best of our knowledge, there are no large-scale comparisons between incomplete ERAS (compliance < 70%) and non-ERAS. The aim of this comparative study is to analyze and evaluate the long-term outcomes of incomplete ERAS in laparoscopic colorectal cancer surgery.

Inclusion Criteria:

• 1. age older than 18 years;2. pathological diagnosis of colorectal cancer;3. radical surgery was performed; and 4. laparoscopic surgery was performed.

Exclusion Criteria:

• 1. ERAS compliance ≥70%; 2. open surgery; 3. switch to laparotomy after laparoscopic surgery; 4. pregnancy or lactation; 5. severe mental illness; 6. Simultaneous malignant tumors of multiple organs; 7. History of other malignant tumors; and 8. Emergency radical colorectal resection due to obstruction, perforation or bleeding.
