A Meta analysis for 4250 portal hypertension cases undergoing surgery in Chinese literature / 中华普通外科杂志

ABSTRACT

ObjectiveTo systematically evaluate the therapeutic effect of gastroesophageal devascularization( GD),portasystemic shunt( PSS),devascularization plus portasystemic shunt ( GD + PSS) for the treatment of 4250 cirrhotic portal hypertension cases reported in Chinese literature. MethodsThe literatures about the effect of gastroesophageal devascularization,portasystemic shunt,devascularization plus portasystemic shunt on portal hypertension were collected from Wanfang databases, China National Knowledge Infrastructure(CNKI) from 1980 to 2011.RevMan 4.2 and SPSS 13.0 were used for data analysis. ResultsIn this study 17 reports were enrolled into the meta-analysis.The results of the mta-analysis showed that long term survival rate in the group of GD plus PSS was higher than that in group of GD [OR=1.73,95％CI (1.23,2.44),P ＜0.01].That in group of PSS was similar with the group of GD [ OR =0.87,95 ％ CI (0.63,1.20),P =0.40 ].That of group GD plus PSS was similar with the group of PSS [ OR =1.73,95％ CI (0.95,3.13),P =0.07 ].For recurrent variceal bleeding rate,that in group of PSS was lower than that in the group of GD[ OR =0.46,95％ CI (0.35,0.61 ),P ＜0.01 ].That in the group of GD plus PSS was lower than that in the group of GD [ OR =0.25,95％ CI (0.18,0.35),P ＜ 0.01 ].The group of GD plus PSS was similar to that of group of PSS [ OR =0.72,95％ CI ( 0.40,1.29 ),P =0.27 ].Encephalopathy rate was higher in the group of PSS than the group of GD [ OR =3.57,95％ CI (2.43,5.23 ),P ＜0.01 ].That in group of GD plus PSS was lower than that in the group of PSS[ OR =0.37,95％ CI (0.20,0.69),P ＜0.01 ],while that in GD plus PSS was similar to the group of GD[ OR =1.58,95％ CI (1.02,2.43),P =0.04 ].ConclusionsThe only significant factor influencing the long term result in Chinese patients with portal hypertension is preoperative liver function.The three types of operation have different benefits and disadvantages.
