腹膜后自体脾移植术在肝硬变门静脉高压症治疗中的临床研究

目的　观察腹膜后自体脾移植联合食管下段横断术治疗肝硬变门静脉高压症的临床效果。方法　将20例肝功能Child A、B级的肝硬变门静脉高压症患者随机均分为自体脾移植组和切脾组。自体脾移植组采用自体带蒂脾组织腹膜后移植联合改良的食管下段横断术,切脾组则采用脾切除联合改良的食管下段横断术。以患者术前的情况为对照,在术后2~6 个月观察患者的一般情况、脾扫描、肝功能、血清促吞噬素(tuftsin)及IgM水平。结果　术后第6天切脾组死亡1例,术后第10天脾移植组出现再出血1 例。自体脾移植组术后血清tuftsin、IgM水平高于切脾组,差异有显著性意义(P<0.01),而对肝功能无明显影响。结论　腹膜后自体脾移植能维持脾脏的基本免疫功能,且能长期存活,在临床上推广应用是可行的。

Clinical Study of Retroperitoneal Splenic Autotransplantation Combined with Lower Esophagus Transection in Treatment of Hepatic Cirrhosis Induced Portal Hypertension

Objective To inquire the therapeutic effect of retroperitoneal splenic autotransplantation combined with lower esophageal transection in the treatment of hepatic cirrhosis induced portal hypertension with randomized comparasion.Methods The hepatic cirrhosis induced portal hypertension patients with Child A or B grade of liver function were randomly divided into splenic autotransplantation group and splenectomy group.In the splenic autotransplantation group, retroperitoneal transplantation of pedicled autosplenic tissue combined with modified lower esophageal transection was performed,while in the splenectomy group, splenectomy combined with modified lower esophageal transection was conducted.The general conduction, splenic scanning, liver function, serum tuftsin and IgM levels in patients were observed 2 to 6 months after operation, and compared with those before operation. Results One patient died in the splenectomy group on the 6th postoperative day, rebleeding occurred in one case of the splenic autotransplantation group. The levels of tuftsin and IgM in splenic autotransplantation group were higher than those of splenectomy group after operation, with significant difference ( P <0.01). The liver function between two groups showed no difference ( P >0.05).Conclusion Spleen autografts could maintain the basic immune function of spleen and survive for a long time.
