Application efficacy of three-dimensional visualization technology,fluorescent imaging system and intraoperative ultrasound for laparoscopic anatomical liver resection
Objective To summarize the experiences of laparoscopic anatomical liver resection through a combination of three-dimensional 3D visualization technology,fluorescent imaging system and Intraoperative ultrasound.Methods From January 2023 to December 2023,the relevant clinical data were retrospectively reviewed for 22 patients of primary liver cancer undergoing laparoscopic anatomical liver resection.Before surgery,a three-dimensional visualization model of liver was established and surgical path planned.During surgery,anatomical liver resection was performed with fluorescent imaging technology and intraoperative ultrasound.Results All operations were successful on the basis of preoperative plan.Indocyanine green(ICG)stain was successful(n=21).One case of unsuccessful ICG stain was due to severe liver cirrhosis.The pathological diagnoses were hepatocellular carcinoma(n=20),cholangiocarcinoma(n=1)and mixed liver cancer(n=1).All margins were negative.All of them recovered well after surgery and were discharged uneventfully.There was no tumor recurrence during a postoperative follow-up period of(2-8)months.Conclusion A combination of 3D visualization,ICG fluorescent imaging and intraoperative ultrasound provides a solid foundation for laparoscopic anatomical liver resection.
