IV lidocaine during colon cancer surgery to lower inflammation and speed recovery

Effect of Perioperative Intravenous Infusion of Lidocaine on the Postoperative Course and the Immune Response in Patients Undergoing Surgery for Colon Cancer - the PILDI Study

Phase 2 Interventional Institute of Oncology Ljubljana · NCT06923787

This trial will test if an intravenous lidocaine infusion given around the time of surgery can lower inflammation, reduce pain and opioid use, and help bowel function recover faster in adults having laparoscopic colon cancer surgery.

What this trial studies

This is a randomized, double-blind, placebo-controlled Phase 2 trial comparing perioperative intravenous lidocaine (and a comparator arm with high-dose dexamethasone) to placebo in adults undergoing elective laparoscopic colon resection with anastomosis. The study measures changes in pro-inflammatory markers, postoperative pain scores, opioid consumption in the first 48 hours, and time to first postoperative bowel movement. Eligible patients are adults 18–80 years old with colon cancer and ASA class up to 3, while those receiving neoadjuvant chemotherapy or with significant cardiac, hepatic, renal, neurologic, or infectious contraindications are excluded. The protocol is conducted at the Institute of Oncology Ljubljana with perioperative monitoring and blinded outcome assessment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18–80 with colon cancer scheduled for elective laparoscopic colon resection and colonic anastomosis, ASA class ≤3, who are not receiving neoadjuvant chemotherapy and can provide informed consent.

Not a fit: Patients who are pregnant or breastfeeding, receiving neoadjuvant chemotherapy, or who have excluded conditions such as significant cardiac arrhythmias, severe liver or renal disease, epilepsy, or other listed contraindications are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, perioperative IV lidocaine could reduce inflammation and pain, lower opioid requirements, speed return of bowel function, and shorten early recovery after colon cancer surgery.

How similar studies have performed: Multiple prior studies in general surgical populations have shown that perioperative IV lidocaine can reduce postoperative pain, opioid use, and speed return of bowel function, but data specifically linking lidocaine to immune marker changes and cancer outcomes are limited.
