Objective:To investigate the clinical value of indocyanine green (ICG) staining technique combined with laparoscopic hepatectomy with a Glisson pedicle approach in the treament of liver cancer.Methods:The clinical data of 150 patients with primary liver cancer, who received treatment in Yuyao People's Hospital from January 2019 to December 2020, were retrospectively analyzed. Group A ( n = 82) and group B ( n = 68) were designated according to the surgery methods used. The group A was subject to laparoscopic hepatectomy with a Glisson pedicle approach. The group B received ICG staining technique combined with laparoscopic hepatectomy with a Glisson pedicle approach. Operation-related conditions, postoperative complications, and the change in liver function indexes after surgery relative to before surgery were compared between the two groups. Results:There were no significant differences in the time taken to first anal exhaust, extubation time, and length of hospital stay between group A and group B (all P > 0.05). Operative time and intraoperative bleeding in the group B were (205.04 ± 35.01) minutes and (230.05 ± 17.53) mL, respectively, which were significantly lower than those in the group A [(228.07 ± 28.05) minutes, (255.07 ± 19.00) mL, t = 4.47, 8.31, both P < 0.05]. R0 resection rate was significantly lower in group B than in group A [85.29% (58/68) vs. 70.73% (58/82), χ2 = 4.50, P < 0.05]. There were no significant differences in postoperative complications between the two groups ( P > 0.05). Before treatment, there were no significant differences in serum levels of alanine aminotransferase (ALT), aspartate transaminase (AST), and total bilirubin between the two groups (all P > 0.05). At 1 day after surgery, serum ALT, AST, and TBil levels in each group were significantly increased compared with before surgery (all P < 0.05). Furthermore, serum levels of ALT, AST and TBil in the group A were (108.51 ± 30.23) U/L, (107.66 ± 26.93) U/L, and (32.16 ± 4.73) μmol/L, respectively, which were significantly higher than those in the group B [(88.38 ± 24.76) U/L, (86.85 ± 19.74) U/L, (27.95 ± 4.31) μmol/L, t = 4.40, 5.30, 5.65, all P < 0.05]. At 3 days after surgery, serum levels of ALT, AST, and TBil in each group were significantly lower than those at 1 day after surgery, but they were still higher than those before surgery. At 3 days after surgery, serum levels of ALT, AST and TBil in group A were (74.20 ± 13.83) U/L, (65.22 ± 9.68) U/L, and (28.18 ± 4.14) μmol/L, respectively, which were significantly higher than those in group B [(54.72 ± 10.31) U/L, (55.41 ± 7.63) U/L, (24.25 ± 3.98) μmol/L, t = 9.61, 6.79, 5.89, all P < 0.05]. Conclusion:Although the ICG staining technique has certain limitations, it can improve the accuracy of hepatectomy to a certain extent. ICG staining technique combined with laparoscopic hepatectomy with the Glisson pedicle approach is a safe and accurate treatment for liver cancer. The combined therapy is worthy of clinical application.
