13. Microwave coagulation versus sclerotherapy after band ligation for treatment of esophageal varices in cirrhotic / Coagulação por microondas versus escleroterapia apos ligadura elastica endoscopica para tratamento de varizes esofagicas em cirroticos
Antecedentes: A ligadura elástica endoscópica (LE) é um dos métodos mais utilizados para profilaxia secundária de sangramento por varizes esofágicas, mas a recorrência varicosa é freqüente após este tratamento. A associação de LE com escleroterapia endoscópica por injeção (EI) reduz este risco. A coagulação por microondas (MC) é um método

14. O papel da cirurgia de descompressão portal e o desenvolvimento de insuficiência hepática no curso evolutivo da esquistossomose hepatoesplênica.
Morbidity and mortality of hepatosplenic schistosomiasis (HSS) are basically determined by portal hypertension and gastrointestinal bleeding due to rupture of esophageal and gastric varices. Based on the classic concept that HSS is a fibrosing condition, which does not affect liver function, the surgical treatments have been considered an efficient and safe

15. Remodeling of hepatic vascular changes after specific chemotherapy of schistosomal periportal fibrosis
Hepatosplenic schistosomiasis was the first human disease in which the possibility of extensive long standing hepatic fibrosis being degraded and removed has been demonstrated. When such changes occurred, the main signs of portal hypertension (splenomegaly, esophageal varices) progressively disappeared, implying that a profound vascular remodeling was concom

16. Fatores preditivos clínicos e laboratoriais de varizes esofágicas em crianças e adolescente com síndrome de hipertensão porta.
The objective of this study is to determine the clinical and laboratory parameters that could help predict the presence of esophageal varices in children and adolescents with portal hypertension syndrome. All 111 children and adolescents with portal hypertension syndrome without previous history of upper gastrointestinal bleeds admitted to the Outpatient Ped

17. TIPS for controlling clinical complications in portal hypertension / Tips para o controle das complicações clinicas da hipertensão portal
Objetivo: O propósito deste estudo foi avaliar a eficácia do procedimento denominado TIPS (Transjugular Intrahepatic Portosystemic Shunt) em pacientes com hepatopatia crônica e hipertensão portal, verificar a incidência de complicações e a existência de fatores prognósticos da evolução clínica. Casuística e Método: Foram revistos todos os proce

18. 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

19. Surgical indication in Schistosomiasis mansoni portal hypertension: follow-up from 1985 to 2001
The study had the objective to evaluate the benefits of surgical indication for portal hypertension in schistosomiasis patients followed from 1985 to 2001. Schistosoma mansoni eggs were confirmed by at least six stool examinations or rectal biopsy. Clinical examination, abdominal ultrasonography, and digestive endoscopy confirmed the diagnosis of esophageal

20. Surgical hepatosplenic mansonic schistosomiasis in adolescents: repercussions of the post-treatment schistosomotic burden on the hepatic functional reserve
Schistosomiasis mansoni affects the hepatic functional reserve. Clinical treatment with oxamniquine is not 100% effective and there has been found strain of this parasite resistant to this drug. The aims of this investigation were: (1) to examine the presence of residual parasite burden after medical and surgical treatment on adolescents with surgical schist

21. A 15-year experience of injection sclerotherapy in adult patients with extrahepatic portal venous obstruction.
OBJECTIVE: The authors report a 15-year experience with injection sclerotherapy in the management of adult and teenage patients with esophageal varices due to extrahepatic portal venous obstruction (EHPVO). SUMMARY BACKGROUND DATA: Extrahepatic portal venous obstruction is an uncommon cause of esophageal varices and is associated with normal liver function.

23. 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

24. Should ablative operations be used for bleeding esophageal varices?
To evaluate the long-term success of an ablative procedure for esophageal varices, the clinical results of 60 standardized, non-shunt (Womack) operations performed from 1953-1974 were reviewed. The overall operative mortality in this series was 35%. The 39 patients surviving operation have been followed from 5 to 21 years (mean: 13.3 years). Excluding operat
