Test pain treatment guided by a heart-based index after bowel surgery
Part of Digestive system, Pain clinical trials.
This trial studies whether using a monitor-based pain number (called the ANI) to guide pain medicine can improve bowel function after laparoscopic surgery for colorectal cancer. It may help reduce constipation or slow gut recovery by matching pain treatment to your body’s signals.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be age 19 or older.
- Plan to have laparoscopic surgery for colorectal cancer at Gangnam Severance Hospital.
- Surgery must be planned (not emergency surgery).
- You must not have had prior open abdominal surgery.
- You should not have conditions or devices that affect heart rhythm, such as serious arrhythmia or a pacemaker, and no history of heart transplant.
- You can’t take certain meds that may interfere with the ANI reading (for example: antimuscarinics, alpha-agonists, or beta blockers), and you should not be on long-term opioid pain medicines.
- You must be able to understand and read the consent form.
- You should not have cognitive impairment that prevents informed consent.

This study checks whether using a pain-activity monitor during robot-assisted colorectal surgery can help the surgical team choose the right pain medicine. It may improve comfort and reduce the chance of giving too much or too little pain medicine.
This trial tests a device that monitors your pain level during surgery using a special index called the Nociception Level Index. It may help doctors manage your pain better without using too much medicine.
This trial tests a new pain medication (anrikefon) that patients can control themselves by pressing a button after laparoscopic colon surgery. The goal is to see if it works better or safer than standard pain relief, especially for patients whose nerve blocks alone don't fully control pain.
This trial tests whether a small electrical device placed on the skin behind your ankle can help improve bowel control after surgery to remove rectal cancer. Many patients experience changes in bowel function after this surgery, and this treatment may help restore normal continence.
This study compares different methods of managing pain after minimally invasive surgery for abdominal cancers. It aims to find which approach works best to reduce pain and improve recovery.
This study tests a new way to monitor pain after lower back surgery using a device called ANI, which tracks your body's response to pain. The goal is to see if this method helps doctors give you better pain relief.
