目的探讨常温下第一肝门阻断对肝右叶手术出血量及肝功能的影响。方法呃生总结23例肝右叶部分切除术的临床资料,分为第一肝门阻断组8例与非阻断组15例。对比2组间手术时间、出血量及手术前后肝功能的变化。结果两组间手术时间(133.8±20.6;147.5±29.4min)和出血量(357.1±207.8;275±238.2mL)无明显差别。未阻断组手术前后AST(39.8±8.5;79±23.1,P<0.01),ALT(45.38±35;136±56,P<0.05)明显升高,而阻断组变化不显著。结论常温下第一肝门阻断对肝右叶手术的手术时间和出血量无影响,但短时间肝门阻断可能对肝功能有保护作用。
Objective To investigate the effect of first hepatic portal obstruction on the amount of hemorrhage and hepatic function in the right lobe of liver at room temperature. Methods The clinical data of 23 cases of partial resection of the right lobe of the liver were summarized and divided into 8 cases in the first hepatic obstruction group and 15 cases in the non-obstructive group. The operation time, blood loss and changes of liver function before and after surgery were compared between two groups. Results There was no significant difference in operative time (133.8 ± 20.6; 147.5 ± 29.4 min) and bleeding volume (357.1 ± 207.8; 275 ± 238.2 mL) between the two groups. The levels of AST (39.8 ± 8.5; 79 ± 23.1, P <0.01), ALT (45.38 ± 35; 136 ± 56, P <0.05) before and after operation in the non-occlusion group were significantly increased, while those in the occlusion group did not change significantly. Conclusions The first hepatic hilar block has no effect on the operation time and bleeding volume of the right lobe of liver at room temperature, but the short-term hepatic portal blockade may have a protective effect on liver function.
