Patient selection: portal hypertension, splenectomy plus pericardial devascularization (traditional or simplified)
Outcome: 5-year overall survival after surgery
Parameters:
(1) age in years, from 20 to 80 years
(2) operative time in minutes, from 40 to 320 minutes
(3) serum ALT in IU/L, from 0 to 800 IU/L
(4) ALBI, from -3.6 to -0.6
points for age =
= (1.5 * (years)) - 30
points for operative time =
= (0.22714 * (time)) - 9.08571
points for serum ALT =
= (0.125 * (ALT))
points for ALBI =
= (28 * (ALBI)) + 100.8
total score =
= SUM(points for all 4 parameters)
Interpretation:
• minimum score: 0
• maximum score: 337.6
• The higher the score the lower the 5-year overall survival.
