[Deterioration of liver function following endoscopic injection sclerotherapy of esophageal varices--significance of the new liver function test "intravariceal injection (I.I.) index"].
Changes of liver functions associated with endoscopic injection sclerotherapy (EIS) were investigated in 143 patients with remarkable esophageal varices. The index used for evaluating hepatic reserve was the ratio between the increase of total bilirubin and the increase of LDH after EIS [I.I. index = (delta T.Bil./delta LDH) x 100] in cases treated by intravariceal injection of 5% ethanolamine oleate. I.I. index value caused by hemolysis was stable and always below 0.2, while the elevation of I.I. index above 0.2 was regarded as the reflection of the deterioration of liver function. After the entire sessions of EIS, the changes of liver function tests before and after EIS were estimated in 104 cases using 3 factors as follows; (1) delta T.Bil.; increase of total bilirubin more than 0.5 mg/dl (2) delta PT; decrease of prothrombin time more than 5% (3) delta ICG R15; increase of ICG R15 more than 5%. I.I. index of group I (without any changes of 3 factors mentioned above; n = 66) was 0.22 +/- 0.16, approximately within normal range. However, in group II (with 1 factor; n = 29), group III (with 2 factors; n = 5), group IV (with all factors; n = 4), I.I. index was elevated according to the severity of their liver dysfunction. The cases whose I.I. index value increased gradually during the course of EIS, were apt to deteriorate the liver functions and therefore, should be carefully observed. Also, I.I. index seems to reflect the prognosis of the patients treated by EIS for some extent, since the survival period of the cases treated by EIS were correlative with the value of I.I. index (r = -0.542, p < 0.01), and I.I. index of 32 cases who survived for longer than 5 years after EIS was almost normal (0.22 +/- 0.15).
