Summary
High-energy laser irradiation effectively manages hepatic bleeding and bile flow in liver disease patients. This innovative approach in hepatic surgery shows significant clinical promise with minimal complications.
Area of Science:
- Hepatology
- Surgical Technology
- Biomedical Engineering
Background:
- Liver diseases present challenges in managing parenchymal hemostasis and cholestasis.
- Traditional surgical methods for liver resection can lead to significant bleeding and bile leakage.
Purpose of the Study:
- To evaluate the efficacy of high-energy laser irradiation in achieving hemostasis and cholestasis during liver surgery.
- To assess the safety and clinical usefulness of laser applications in treating various hepatic diseases.
Main Methods:
- Utilized carbon dioxide (CO2) laser and YAG laser irradiation on liver wound surfaces in 48 patients.
- Employed a contact laser scalpel for tissue incision in 4 patients.
- Applied mechanical suturing devices for hermetization of vessels and bile ductules during liver resections in 19 patients.
Main Results:
- Laser irradiation successfully provided adequate parenchymal hemo- and cholestasis in patients with hepatic diseases.
- No complications directly related to laser application were observed.
- A low mortality rate of 4.2% (2 patients) was recorded post-operation.
Conclusions:
- High-energy laser irradiation is an effective tool in hepatic surgery for controlling bleeding and bile flow.
- Laser application demonstrates significant clinical usefulness and safety in managing hepatic diseases.
- The study supports the integration of laser technology into routine hepatic surgical practice.
