采用前瞻性对比方法，研究断流与分流两种手术方式对门静脉高压性胃病（ＰＨＧ）的影响。将１９９４年１月至１９９６年４月入院的２６例肝硬变、门静脉高压症病人随机分为两组，分别施行断流术（１５例）与分流术（１１例），手术前后行胃镜检查，对比胃粘膜损害的镜下变化。结果表明，断流组ＰＨＧ的病变程度加重（Ｐ＝０．０３５４），而分流组ＰＨＧ则明显改善（Ｐ＝０．０２７３）。认为临床上有必要对断流术进行改良，或重新评价断流术与分流术的临床疗效。
A prospective and comparative study was conducted to investigate the effects of both flow-breaking and shunting on portal hypertensive gastropathy (PHG). Twenty-six patients with cirrhosis and portal hypertension who were admitted to hospital from January 1994 to April 1996 were randomly divided into two groups. The patients underwent both radical surgery (15 cases) and shunt (11 cases). The patients underwent gastroscopy , Compared with microscopic changes in gastric mucosal damage. The results showed that the extent of PHG in the discontinuous group was increased (P = 0.0354), while PHG in the shunt group was significantly improved (P = 0.0273). It is considered that it is necessary to improve the clinical effect of disconnection and reevaluate the clinical efficacy of disconnection and shunt.
