This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing whether a nerve block procedure using ropivacaine hydrochloride can help people recover better and feel less pain after laparoscopic surgery to remove colorectal cancer. Half of the participants will receive the nerve block with the active medication, while the other half will receive a placebo (a sham block with salt water). Researchers will measure how well people feel 24 hours after surgery, including their pain levels, how much pain medication they need, and when they return to normal eating.
After colorectal cancer surgery, patients often experience significant pain and other complications that slow their recovery. This trial is investigating whether this nerve block treatment could reduce pain and help people get back to normal activities faster as part of a comprehensive recovery program.

You will be randomly assigned to receive either the active nerve block or a placebo block before your laparoscopic colorectal cancer surgery. You will not know which one you receive. After surgery, researchers will ask you questions about your recovery and pain levels at 24 hours and 48 hours, track how much pain medication you need, and monitor how quickly you return to eating normally and leave the hospital. Your hospital stay will follow the standard recovery protocol.
