Using breath carbon monoxide to predict liver recovery after partial hepatectomy

Official title: Postoperative Heme Oxygenase Induction and Carbon Monoxide Production as a Novel Method to Assess Hepatic Regeneration and Predict Hepatic Related Morbidity After Partial Hepatectomy

Run by Englewood Hospital and Medical Center · NCT06681818 · Data updated 2026-11-12

This will test whether measuring carbon monoxide in breath can help predict how well adults recover liver function after part of their liver is removed.

Is this trial a fit for you?

Likely a good fit

Adults planning partial liver resection for primary liver tumors or metastatic disease who can understand and sign informed consent are ideal candidates.

Probably not a fit

Patients under 18, those unable to consent or perform breath testing, or those with factors that prevent accurate CO measurement are unlikely to benefit from this protocol.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The study will measure endogenous carbon monoxide production with a commercial breath CO monitor (smokerlyzer) in adults undergoing partial liver resection. Investigators will relate breath CO levels to the extent of hepatic resection and to postoperative measures of liver regeneration and function. Measurements will be taken before and after surgery to track changes over time and correlated with clinical outcomes. The approach seeks a noninvasive biomarker that could indicate patients at higher risk for liver-related morbidity after resection.

Why it matters

Potential benefit: If successful, this could provide a simple, noninvasive breath test to help identify patients likely to regenerate liver tissue well or at risk for postoperative liver complications.

How similar studies have gone: Some prior work has measured heme oxygenase activity and breath CO in liver disease, but using breath CO specifically to predict post-hepatectomy regeneration is relatively novel and not yet proven.
