13. Esplenectomia e ligadura da veia gÃstrica esquerda na esquistossomose mansÃnica: efeitos sobre pressÃo das varizes do esÃfago, indicadores endoscÃpicos e dopplerfluxometria portal
The effects of splenectomy and gastric vein ligation on the main risk factors of bleeding from esophagogastric varices were studied in 34 patients with the hepatosplenic form of schistosomiasis mansoni and a history of gastrointestinal hemorrhage. The following parameters were investigated: i) esophageal variceal pressure, measured by the endoscopic pneumati

14. Hiperesplenismo na esquistossomose mansÃnica : o baÃo e as cÃlulas sanguÃneas antes e depois de esplenectomia
Seventy eight patients with chronic hepatosplenic schistosomiasis underwent left gastric vein ligature and also splenectomy as a complementary measure for treatment of portal hypertension after upper gastrintestinal tract bleeding. Weight and clinical measurements of spleens were taken in order to study their relationship with blood counts, the variability b

15. Echo-Doppler evaluation of reverse flow sign in the intrahepatic portal branches after surgery.
OBJECTIVE: The author's evaluated the clinical significance of the development of reversed portal flow after abdominal surgery other than portosystemic shunt procedure. SUMMARY BACKGROUND DATA: There have been several reports in regard to reversed portal flow demonstrated by pulsed Doppler ultrasonography, most of which were related to portal hypertension. T

16. Fifty years of surgery for portal hypertension at the Cleveland Clinic Foundation. Lessons and prospects.
OBJECTIVE: The 50-year experience with surgery for the treatment of portal hypertension and bleeding varices at the Cleveland Clinic is reviewed. SUMMARY BACKGROUND DATA: A variety of procedures have been used to treat bleeding varices during the past 50 years. These include transesophageal ligation of varices or devascularization of the esophagus and stomac

17. Long term outcome after surgery for extrahepatic portal vein thrombosis.
The long term outcome of 21 children with extrahepatic portal hypertension secondary to portal vein thrombosis managed by surgical intervention was evaluated. Portosystemic shunts, used primarily in nine patients (eight central splenorenal, one mesocaval) after conservative treatment had failed, had no associated mortality and a 56% patency rate. Five of the

18. Prophylactic portal nondecompression surgery in patients with esophageal varices. An interim report.
This is an interim report of a prospective controlled study to evaluate prophylactic surgery in 112 patients with portal hypertension and esophageal varices treated since 1980. Methods of operation were confined to those with the least influence on portal circulation, namely selective shunts and nonshunting direct interruption procedures. The bleeding rates

19. Dogs with experimental cirrhosis of the liver but without intrahepatic hypertension do not retain sodium or form ascites.
Dogs with portal cirrhosis but without portal hypertension (end-to-side portacaval anastomosis) retain sodium and expand plasma volume before ascites formation. In our study, dogs were subjected to bile duct ligation and simultaneous side-to-side portacaval anastomosis (PCA) in order to create a canine model of hepatic cirrhosis without intrahepatic or porta

20. The changing spectrum of treatment for variceal bleeding.
OBJECTIVE: The objective of this study was to assess the impact of endoscopic therapy, liver transplantation, and transjugular intrahepatic portosystemic shunt (TIPS) on patient selection and outcome of surgical treatment for this complication of portal hypertension, as reflected in a single surgeon's 18-year experience with operations for variceal hemorrhag

21. How to minimize blood loss during liver surgery in patients with cirrhosis
Patients with liver disease frequently have substantial changes in their haemostatic system. This is reflected in abnormal test results on routine coagulation screening assays such as the prothrombin time (PT), activated thromboplastin time (APTT) and platelet count. Traditionally, attempts were made to correct abnormalities in the haemostatic system as meas

22. Proximal splenorenal shunts for extrahepatic portal venous obstruction in children.
OBJECTIVE: The results of proximal splenorenal shunts done in children with extrahepatic portal venous obstruction were evaluated. SUMMARY BACKGROUND DATA: Extrahepatic portal venous obstruction, a common cause of portal hypertension in children in India, is being treated increasingly by endoscopic sclerotherapy instead of by proximal splenorenal shunt. It i

23. Current management of biliary atresia
Extra‐hepatic biliary atresia occurs in approximately 1:15 000 live births leading to about 50 new cases/year in the UK. Presentation is with prolonged jaundice, usually in a term baby who develops signs of obstructive jaundice. Management has been improved by public and professional education to encourage early referral and diagnosis to facilitate initi

24. Portal thrombosis in cirrhotics. A retrospective analysis.
The development of thrombotic obstruction in the portal bed of cirrhotic patients presents special problems in diagnosis and treatment. In the cirrhotic population treated for portal hypertension at our Surgical Department during the period 1967-1983 (512 patients), the incidence of thrombosis in the portal bed was 16.6% (85 patients). Bleeding was the main
