Major hepatic tumor resection using profound hypothermia and circulation arrest
Journal of Pediatric Surgery
|June 1, 1981
Summary
Hypothermic circulatory arrest significantly reduces operative risks for pediatric liver tumors. This technique allows for bloodless dissection, improving outcomes in complex partial hepatectomy procedures for children.
Area of Science:
- Pediatric Surgery
- Surgical Oncology
- Hepatobiliary Surgery
Background:
- Malignant liver tumors in children present significant operative challenges, including high morbidity and mortality.
- Massive blood loss and intraoperative cardiac arrest are critical risks during partial hepatectomy for large pediatric liver tumors.
- Dissection of retrohepatic caval and hepatic veins is particularly hazardous, often necessitating hurried procedures.
Purpose of the Study:
- To evaluate the efficacy of profound hypothermia with circulatory arrest in managing huge malignant liver tumors in children.
- To mitigate intraoperative complications such as excessive bleeding and cardiac arrest during extended hepatic lobectomy.
Main Methods:
- Six pediatric patients with extensive malignant liver tumors underwent surgical exploration via midline abdominal incision, extended to a sternal split or thoracoabdominal incision.
- Cardiopulmonary bypass was initiated, followed by cooling to a rectal temperature below 20°C for circulatory arrest.
- Extended hepatic lobectomy was performed during the period of circulatory arrest, followed by rewarming and completion of the procedure.
Main Results:
- Profound hypothermia and circulatory arrest provided up to one hour of bloodless dissection, facilitating easier tumor resection.
- This technique transformed the most challenging aspect of liver tumor surgery into the simplest part of the procedure.
- Post-operative bleeding was controlled, and the remaining surgical steps were completed successfully.
Conclusions:
- Profound hypothermia with circulatory arrest is a highly effective and recommended approach for selected pediatric cases with large, resectable malignant liver tumors.
- This technique significantly enhances surgical safety and feasibility in complex pediatric liver resections.
- The method addresses critical intraoperative challenges, improving the overall surgical outcome for pediatric liver cancer.
