脾切除贲门周围血管离断术后肝脏血流动力学和储备功能的变化

Objective To observe changes of hepatic hemodynamics and hepatic functional reserve after splenectomy and periesophagogastric devascularization. Methods From July 2006 to August 2007, thirty patients with portal hypertension caused by hepatitis B cirrhosis underwent splenectomy and periesophagogastric devascuiarization. The PVPG (portal venous pressure gradient) was measured by inductor continually during operation. The HAF (hepatic artery flow), PVF (portal venours flow) and hepatic arterial RI(resistant index) were measured with Doppler sonography. The EHBF(effective hepatic blood flow) and ICGR15 (indocyaninegreen retention rate at 15 minutes) were obtained respectively by indocyaninegreen clearance test before and after the operation. Results PVPG after laparotomy (19±4) mm Hg, ligating the splenic artery(14±4) mm Hg, splenectomy(14±3)mm Hg and periesophagogastric devascularization (12±4) mm Hg showed a tendency to decrease progressively. The PVF decreased [from (42±14) ml/s to (16±8) ml/s] and HAF increased in compensation after operation. The EHBF increased [from (0.48±0.10) L/min to (0.56±0.10) L/min], and the ICGR15 decreased (from 23%±8% to 18%±4%) postoperatively. Conclusion After splenectomy and periesophagogastric devascularization, the hepatic functional reserve improves at least in a short term notwithstanding the decrease of PVPG and PVF.

肝癌肝移植术后肝癌复发转移的特点及危险因素

目的探讨肝癌肝移植术后肿瘤复发转移的特点,包括复发部位、复发时间和危险因素。方法收集2005年1月1日~2006年12月31日肝癌肝移植连续患者99例术前、术中、术后资料,排除住院期死亡7例,定期随访,非肿瘤复发死亡5例、失访1例,余86例随访12~35个月,复发转移38例,与未复发组对照,总结复发转移危险因素,采用SPSS统计软件进行统计学分析。结果复发组较未复发组肿瘤数目多、最大肿瘤直径大。术前AFP水平〉400ng/ml、超出米兰标准、TNM分期Ⅲ~Ⅳ期、血管侵犯是肿瘤复发的危险因素。多因素分析显示TNM分期Ⅲ~Ⅳ期是肝移植术后肿瘤复发的独立危险因素。肿瘤血管侵犯是短期内肿瘤复发的危险因素。结论肝癌肝移植术后肿瘤首先复发转移部位较多见于肝外,大肝癌分期差、多伴血管侵犯,复发时间较短。肿瘤TNM分期Ⅲ~Ⅳ期是肿瘤复发的主要危险因素。肿瘤血管侵犯易使肿瘤短期复发。
