摘要

Background

Liver abscess is a common digestive system disorder primarily caused by bacterial infection. Effective treatment often involves drainage, in which ultrasound technology is commonly used to guide puncture and drainage procedures. However, ultrasound has inherent limitations such as suboptimal visualization of abscess boundaries and adjacent vascular anatomy. Indocyanine green (ICG) fluorescence navigation and three-dimensional (3D) visualization are two intraoperative navigation technologies that, when integrated with ultrasound, overcome these constraints. This synergy improves localization accuracy and abscess size assessment, thereby reducing procedural complexity.

Case Description

This article details the case of a 61-year-old male patient hospitalized for a 4-day history of fever of unknown origin, ultimately diagnosed with a pyogenic liver abscess. Preoperative management included standardized antibiotic therapy. The patient subsequently underwent concurrent laparoscopic abscess fenestration and drainage with cholecystectomy. Intraoperative precision localization of the liver abscess was achieved through ultrasound-guided ICG fluorescence imaging integrated with 3D visualization technology, ensuring successful surgical completion. During the 3-month postoperative follow-up, the patient developed no complications.

Conclusion

ICG fluorescence imaging and 3D visualization technologies demonstrate clinical utility in the management of liver abscesses, providing valuable insights for laparoscopic surgical intervention.
