Novel Method to Assess Hepatic Regeneration and Predict Hepatic Related Morbidity After Partial Hepatectomy

July 18, 2025 updated by: Englewood Hospital and Medical Center

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

the investigators will pursue two specific aims: (1) to monitor the extent of heme oxygenase induction (by measuring endogenous CO production) in relationship to the extent of hepatic resection (2) to assess the production of CO in patients following liver resection and correlate these findings to the rate of liver regeneration and liver function.

measurements will be taken pre, then 4 hours and 24 hours post resection

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame

Time Frame: measurements will be taken pre, then 4 hours and 24 hours post resection
patients will be asked to donate exhaled breath into a smokerlyzer device
measurements will be taken pre, then 4 hours and 24 hours post resection
quantity of liver regeneration, liver volume (ml)
Time Frame: one and three months after resection
CT liver volumetric studies
one and three months after resection
quality of hepatic regeneration, normalized liver function
Time Frame: one and three months post resection
