Recidiva hemorrágica em pacientes esquistossomóticos operados

Abstract: Foram estudados, no período de 1987 a 1991, trinta doentes esquistossomóticos submetidos anteriormente a operações não descompressivas para tratamento da hemorragia digestiva alta, e que apresentaram recidiva hemorrágica. Através de endoscopia digestiva alta, ultra-sonografia abdominal e estudo angiográfico, procurou-se determinar o local do novo sangramento e quais os possíveis fatores de recidiva hemorrágica presentes. Procurou-se também determinar a influência da cirurgia anterior no intervalo de tempo deco… Show more

“…Regarding the factors described in the literature to explain rebleeding secondary to gastroesophagic varices, 86.7% of rebleeding episodes were associated with portal vein thrombosis, partial gastroesophagic devascularization or rechanneling of the gastroesophagic venous system, or all these factors concomitantly (1) . However, whereas treatment of recurrent bleeding entails endoscopic programs for the eradication of varices, often scant emphasis is placed on accurate diagnosis of the cause of bleeding, i.e.…”

“…However, non-derivative techniques are associated with a higher incidence of recurrent hemorrhaging and portal vein thrombosis (1,2,13,14,15,16,17,20,24,33,35) . The rate of recurrence of bleeding after treatment using non-derivative techniques varies.…”

“…Os ressangramentos, após operações não derivativas, ocorrem em períodos de tempo variáveis e diferentes fatores podem estar envolvidos 10 . Entendemos que, para o tratamento adequado dos doentes esquistossomóticos com recidiva hemorrágica, após operações não-derivativas, é fundamental conhecer os fatores responsáveis pelo ressangramento e aspectos técnicos da operação realizada anteriormente.…”
