[Value of manometry in establishing the developmental stage of portal hypertension and the effectiveness of therapeutic portacaval shunt].

A total of 105 patients have been studied, operated for portal hypertension, that underwent porto-manometric investigations by various methods, before and during surgery. The study was aimed at establishing indications that can be provided by portal manometry on the evolutive stage of portal hypertension. Correlations have been established between ascitic decompensation, the frequency of superior digestive hemorrhages and the portal pressure. The efficiency of the post-systemic derivation was evaluated manometrically, depending on the type of the anastomosis. Conclusions are presented, on the particular value of the manometric investigation for the correct choice of the porto-caval shunt.
