吲哚菁绿排泄试验评估肝硬化脾切断流术的临床应用

Indocyanine green test to evaluate the clinical application of liver cirrhosis splenectomy and devascularization

目的 :评估吲哚菁绿(indocyanine green,ICG)排泄试验在肝硬化患者行脾切断流术中的临床应用价值。方法:回顾性分析我院收治的肝硬化脾切断流术患者136例,按Child-Pugh分级分组,比较各组ICG血浆清除率(plasma clearance of indocyanine green,K)和吲哚菁绿15 min滞留率(indocyanine green retention rate at fifteen minute,ICGR15)的组间差异,探讨ICG排泄试验与Child-Pugh分级的相关性;按ICGR15值分组,比较各组间术后1周的谷丙转氨酶(alanine aminotransferase,ALT)、总胆红素(total bilirubin,TBil)、凝血酶原时间(prothrombin time,PT)、白蛋白(albumin,Alb)及腹水情况,探讨各变量与ICGR15的相关性。取其中Child A级病例,再分ICGR15≤15%组和ICGR15>15%组,比较术后肝功能不全的发生率。结果:136例患者中,Child A组75例,Child B组59例,Child C组2例(未纳入统计)。Child-Pugh A、B级两组中ICGR15值分别为(16.78±4.84)%和(28.09±7.36)%,K值分别为(0.17±0.08)/min和(0.12±0.05)/min,两组间差异均具有统计学意义(P<0.05),且Child-Pugh评分与ICGR15呈正相关。ICGR15≥30%的患者术后1周TBil、PT和腹水深度明显升高,而Alb水平显著下降(与ICGR15<30%组相比,P<0.05),且ICGR15与术后TBil、PT和腹水深度均存在相关性。另外,ICGR15≥30%的患者术后肝功能不全发生率明显高于ICGR15≤15%组。结论:ICGR15与Child-Pugh分级对于肝硬化脾切除术前评估肝储备功能具有良好的相关性,是对Child-Pugh分级的有益补充,对术前评估肝脏储备功能、选择手术时机颇有裨益。

Objective:To evaluate the clinical value of indocyanine green(ICG) test in liver cirrhosis patients after splenectomy and devascularization. Methods: The data of 136 patients with liver cirrhosis who were treated surgically with pericardial devascularization in our hospital were retrospectively collected. Grouped according to the Child-Pugh classification, each plasma clearance of indocyanine green(K) and indocyanine green retention rate at fifteen minute(ICGR15) and the difference between the two groups, to explore the correlation of ICG test and Child-Pugh classification; by ICG R15 packet, between the postoperative group one week of alanine aminotransferase(ALT), total bilirubin(TBil), prothrombin time(PT), and albumin(Alb), ascites changes of between all variables and ICGR15. Take the Child A case, then ICGR15≤15% group and ICGR15>15% group, compare the postoperative incidence of liver dysfunction. Results: In 136 patients, Child A 75 cases, Child B 59 cases, and Child C 2 cases(not included). The two groups of Child-Pugh class A and class B ICGR15 values respectively(16.78±4.84)%and (28.09 ±7.36)% K value respectively (0.17 ±0.08)/min and (0.12 ±0.05)/min, the difference between the two groups has statistical significance (P<0.05), and Child-Pugh score and ICGR15 was positively related. ICGR15 was greater than or equal to 30% of patients with postoperative TBil, PT and ascites was significantly increased, and Alb level decreased significantly (compared with group ICGR15, P<0.05), there was a correlation between ICGR15 and postoperative TBil, PT and ascites. In addition, ICGR15≥30% patients with postoperative liver dysfunction was significantly higher than that of ICGR15 group,which was less than or equal to 15%. Conclusion: ICGR15 and Child-Pugh classification prior to splenectomy in evaluation liver reserve function with good correlation is beneficial supplement in Child-Pugh classification, on preoperative assessment of hepatic functional reserve, making operation scheme is quite beneficial.
