Electroacupuncture (EA) represents an intervention modality that holds promise for the management of POGD. However, the existing empirical evidence substantiating its efficacy remains scarce. The aim of this study is to evaluate the efficacy and safety of EA as a treatment for POGD in patients undergoing colorectal cancer surgery.</p><p><strong>Methods: </strong>This study is a multicenter, parallel-group, randomized controlled trial, named as CORRECT. CORRECT trial will recruit 300 participants diagnosed with colorectal cancer and about to undergo radical surgery across four sub-centers. The participants will be randomly assigned to one of three groups: the EA group, sham-electroacupuncture group, or control group, with a randomization ratio of 2:2:1. All groups will follow a standardized Enhanced Recovery After Surgery (ERAS) protocol. The EA group will receive EA at acupoints LI4, SJ6, ST36, and ST37, while the SA group will undergo sham-electroacupuncture.
