Abstract:
Objective:To analyze the application value of three-dimensional visualization combined with indocyanine green fluorescence staining in laparoscopic resection of patients with complex liver cancer.Methods:The data of patients with complex liver cancer (liver cancer located in liver segments Ⅶ, Ⅷ, Ⅳa, Ⅴ and caudate lobe) who underwent laparoscopic anatomical liver resection in Zhengzhou University People's Hospital from August 2018 to August 2023 were retrospectively analyzed. A total of 334 patients were enrolled, including 249 males and 85 females, with the age of (57.0±10.6) years. Among the 334 patients, patients who underwent laparoscopic liver resection using three-dimensional visualization combined with indocyanine green fluorescence staining were included in the combined group ( n=128), and the other patients who underwent traditional laparoscopic liver resection were included in the traditional group ( n=206). Propensity score was used to match the preoperative indicators and postoperative pathology between the two groups. The two groups were compared in terms of gender, age, maximum diameter of tumor, alpha-fetoprotein, number of tumors, tumor location, American Society of Anesthesiologists (ASA) grade, operation time, portal occlusion time, intraoperative blood loss, surgical margin and postoperative aspartate transaminase (ALT), alanine transaminase (AST), albumin, total bilirubin, and severe postoperative complications (Clavien-Dindo grade≥grade Ⅲ). The Kaplan-Meier method was used to analyze the prognosis, and the log-rank test was used to compare the survival rate. Results:After propensity score matching, 120 cases were included in the combined group and the traditional group, respectively. There were no significant differences in gender, age, maximum diameter of tumor, alpha-fetoprotein, number of tumors, tumor location, and ASA grade between the two groups (all P>0.05). The intraoperative blood loss in the combined group was 200.0 (150.0, 300.0) ml, and the positive surgical margin rate was 6.7% (8/120), which were lower than 300.0 (150.0, 500.0) ml and 15.8% (19/120) in the traditional group, with statistically significant differences ( Z=-2.43, P=0.015, χ2=5.05, P=0.025). There were no statistically significant differences in the operation time, portal occlusion time, and postoperative ALT, AST, albumin, and total bilirubin between the two groups (all P>0.05). Eight cases (6.7%) in the combined group and 11 cases (9.2%) in the traditional group had severe complications after surgery, and all were discharged after treatment. The 1-, 3-, and 5-year recurrence-free survival rates of the combined group were 83.3%, 61.7%, and 58.3% respectively, while that of the traditional group were 71.7%, 52.5%, and 49.2%, respectively, with significant difference ( χ2=4.57, P=0.031). There was no significant difference in the cumulative survival rate between the combined group and the traditional group ( χ2=0.66, P=0.417). Conclusion:Compared with laparoscopic liver resection, laparoscopic liver resection for patients with complex liver cancer using three-dimensional visualization technology combined with indocyanine green fluorescence staining technology can reduce intraoperative blood loss, positive margin rate, and postoperative recurrence.
