Hydrogen peroxide test for intraoperative bile leak detection

Area of Science:

• Hepatobiliary Surgery
• Surgical Complications
• Diagnostic Techniques

Background:

• Bile leakage (BL) is a frequent complication after liver surgery, occurring in 3-27% of cases.
• Existing methods for detecting BL intraoperatively have limitations and are not foolproof.
• A simpler technique for intraoperative BL detection was investigated.

Purpose of the Study:

• To evaluate the efficacy of topical 1.5% hydrogen peroxide (H2O2) for detecting intraoperative bile leakage from the liver cut surface.
• To compare the H2O2 method with the conventional saline test.

Main Methods:

• The study included 31 patients undergoing liver resection or hepatectomies for living donor liver transplantation.
• Following complete liver resection, both the conventional saline test and the topical 1.5% H2O2 test were applied.
• Patient data from both diagnostic methods were recorded and analyzed.

Main Results:

• The H2O2 method detected bile leakage in 19 patients (61.29%), significantly more than the saline method which identified it in 11 patients (35.48%).
• Statistical analysis revealed a significant difference between the methods (P=0.014 for minor resections, P=0.002 for major resections).

Conclusions:

• Topical application of 1.5% H2O2 is a simple and effective method for detecting bile leakage from the liver surface.
• The H2O2 technique is non-invasive, inexpensive, quick, reproducible, and highly sensitive.
• This method offers an advantageous alternative for intraoperative bile leak detection in liver surgery.
