Abstract:
Objective To assess the value of indocyanine green excretion test in predicting hepatic failure after hepatectomy. Methods The retention rate of indocyanine green at 15 minutes (ICG R15), effective hepatic blood flow (EHBF) and clinical and biochemical parameters of 128 patients who received hepatectomy at the Affiliated Provincial Hospital of Anhui Medical University from June 2007 to June 2008 were detected by pulse dye densitometry. All patients were divided into non-hepatic failure group (n = 110) and hepatic failure group (n =18). ICG R15, EHBF, Child's score, histology activity index (HAI) score, clinical and biochemical parameters and other indexes were analyzed to predict hepatic failure by the t test, chi-square test, linear regression analysis or regression model. The relationship between positive predictive indexes and HAI score was studied. Results Eighteen patients suffered from hepatic failure after operation. ICG R15, Child's score, HAI score of patients without hepatic failure were 9% ±4%, 5.6 ±0.7, 3.8 ±0.5, which were significantly lower than 15% ±6%,6.1 ± 0. 8, 5.0 ± 0. 8 of patients with hepatic failure (t = 11. 121,2. 356, 3. 915, P ＜ 0.05). EHBF of patients without hepatic failure was (1.2 ±0.2) L/min, which was significantly higher than (1.0 ±0.2) L/min of patients with hepatic failure (t = 2. 802, P ＜ 0. 05). In a logistic regression model, age ≥ 65 years, ICG R15 ≥ 14% and EHBF ＜ 1.0 L/min were risk factors of postoperative hepatic failure (x2 = 4. 758, 9.709, 5. 362, P ＜ 0.05).ICG R15 was negatively correlated with EHBF (r =-0. 527, P ＜0.05). HAI score was positively correlated with ICG R15 (r =0. 638, P ＜0.05), while it was negatively correlated with EHBF (r =-0. 445, P ＜0. 05).Conclusions ICG R15 and EHBF are good predictive indicators for hepatic failure after hepatectomy. Patients with ICG R15≥14% and EHBF ＜ 1.0 L/min are prone to have postoperative hepatic failure.
