Abstract:
Objective:To investigate the feasibility and potential of fluorescent cholecystic bile duct visualization with direct intravenous injection of indocyanine green(ICG) in obese patients undergoing laparoscopic cholecystectomy(LC).Methods:The clinical data of 132 patients with LC combined with obesity admitted to the Department of Hepatobiliary and Pancreatic Surgery of the Second People′s Hospital of Changzhou City, affiliated to Nanjing Medical University, from January 2023 to July 2023 were retrospectively analyzed. They were divided into fluorescence group( n=65) and control group( n=67) according to whether indocyanine green fluorescence navigation was used or not. There were 50 males and 82 females, and all the enrolled patients body mass index≥28 kg/m 2. Two groups identify the time of the three tubes, intraoperative bleeding, operation time, postoperative hospitalization time, white blood cell count(WBC), C-reactive protein(CRP), alanine aminotransferase(ALT), gamma-glutamyl transferase(GGT), and postoperative follow-up in the fluorescent and control groups were counted respectively. Measurement data with skewed distribution were expressed as M( Q1, Q3), and intergroup comparisons were performed using the Mann-Whitney U test; counting data were described by frequency(rate), and intergroup comparisons were made by applying the chi-square test, Fisher′s exact probability method, and chi-square corrected test according to the difference in the minimum frequency. Results:Surgery was successfully completed in both groups. Preoperative inflammatory indicators and liver function levels were also not statistically significant( P>0.05). The time to identify the three tubes, operation time, intraoperative bleeding, and postoperative hospitalization in the fluorescence group were 18.00(13.50, 20.00) min, 40.00(30.00, 50.00) min, 5.00(5.00, 10.00) mL, and 2.00(1.50, 3.00) d, and in the control group were 32.00(25.00, 45.00) min, 65.00(50.00, 85.00) min, 41.00(41.00, 46.00) mL, and 4.00(3.00, 5.00) d. The differences between the two groups were statistically significant( P<0.05). The postoperative leukocyte count, postoperative CRP, and postoperative GGT were 9.15(7.10, 11.75)×10 9/L, 7.19(3.22, 20.00) mg/L, and 34.0(20.0, 49.0) U/L in the fluorescence group, and 13.05(11.02, 15.59)×10 9/L, and 18.78(12.90, 32.95) mg/L in the control group, respectively, 82.5(68.5, 114.5) U/L, and the differences between the two groups were statistically significant ( P<0.05). None of the patients showed abdominal pain, abnormal liver function and hepatobiliary ultrasound in the follow-up findings within 2 months after surgery. Conclusion:The effect of obesity, a factor that interferes with ICG fluorescence, is extremely limited, and ICG fluorescence cholangiography is a useful technique in the obese population that not only improves the efficiency of the procedure, but also increases intraoperative safety, with results superior to those of conventional laparoscopic cholecystectomy.
