RESULTS	Comparisons of the above-mentioned clinical indexes between groups showed that the APACHE II score was lower ( 5.1 + / - 2.0 scores vs 9.3 + / - 4.3 scores , P < 0.01 ) ; the incidence of shock was lesser ( 1/20 vs 7/19 ) ; the duration of ARDS , renal failure , cardiac insufficiency , hepatic dysfunction , cerebropathy and enteroplegia , as well as the duration in hospital and the requirement of operation shifting were all shorter significantly ( P < 0.05 ) in the ET group than those in the LT group , but no statistical difference ( P > 0.05 ) was shown in terms of the infection incidence and the mortality .\
