the choice of treatment depends on the timing of diagnosis; however, in this study, surgical revision or correction produced worse outcomes than percutaneous angioplasty. The reduction of risk factors and early detection of vascular complications are key elements to a successful transplantation.

Achalasia symptoms may mimic common diseases in children, and therefore, may delay the diagnosis. This study emphasizes the importance of the clinical symptoms for the diagnosis of achalasia, mainly in those cases with associated disorders.

The prevalence of infected ascites was 29.2%. With the exception of serum albumin, there were no differences in the clinical and biochemical features of patients with infected ascites and noninfected ascites.

Children with portal hypertension with a CPR below 114 and a risk score greater than -1.2 are more likely to have present EV. Therefore, these two tests can be helpful in selecting children for endoscopy.

Ghrelin showed an inverse correlation with age and leptin showed a direct correlation with anthropometric parameters and female gender in healthy children. Insulin did not show any correlation.

Objective: To evaluate epidemiological, clinical and prognostic characteristics of children with biliary atresia.Methods: Data regarding portoenterostomy, liver transplantation (LTx), age at last follow-up and survival were collected from the records of patients followed up in six Brazilian centers and compared regarding decades of surgery.Results: Of 513 patients, 76.4% underwent portoenterostomy [age: 60-94.7 (82.6±32.8) days] and 46.6% underwent LTx. In 69% of cases, LTx followed portoenterostomy, whereas in 31% of cases LTx was performed as the primary surgery. Patients from the Northeast region underwent portoenterostomy later than infants from Southern (p = 0.008) and Southeastern (p = 0.0012) Brazil, although even in the latter two regions age at portoenterostomy was higher than desirable. Over the decades, LTx was increasingly performed. Overall survival was 67.6%. Survival increased over the decades (1980s vs. 1990s, p = 0.002; 1980s vs. 2000s, p < 0.001; 1990s vs. 2000s, p < 0.001). The 4-year postportoenterostomy survival, with or without LTx, was 73.4%, inversely correlated with age at portoenterostomy (80, 77.7, 60.5% for ≤ 60, 61-90, > 90 days, respectively). Higher survival rates were observed among transplanted patients (88.3%). The 4-year native liver survival was 36.8%, inversely correlated with age at portoenterostomy (54, 33.3, 26.6% for ≤ 60, 61-90, > 90 days, respectively). Conclusions:This multicenter study showed that late referral for biliary atresia is still a problem in Brazil, affecting patient survival. Strategies to enhance earlier referral are currently being developed aiming to decrease the need for liver transplantation in the first years of life.

ResumoObjetivo: Avaliar as características epidemiológicas, clínicas e prognósticas de crianças com atresia biliar. Os pacientes da região Nordeste foram submetidos a portoenterostomia mais tardiamente do que as crianças das regiões Sul (p = 0,008) e Sudeste (p = 0,0012), embora, mesmo nas duas últimas regiões, a idade no momento da portoenterostomia tenha sido superior ao desejável. Ao longo das décadas, houve aumento progressivo do número de TxH realizados. A sobrevida global foi de 67,6%. A sobrevida aumentou nas últimas décadas (anos 1980 versus 90, p = 0,002; anos 1980 versus 2000, p < 0,001; anos 1990 versus 2000, p < 0,001). A sobrevida de 4 anos pós-portoenterostomia, com ou sem TxH, foi de 73,4%, inversamente correlacionada à idade no momento da portoenterostomia (80, 77,7, 60,5% para ≤ 60, 61-90, > 90 dias, respectivamente). Os pacientes transplantados apresentaram taxas de sobrevida mais elevadas (88,3%). A sobrevida de 4 anos com fígado nativo foi de 36,8%, inversamente correlacionada à idade no momento da portoenterostomia (54, 33,3, 26,6% para ≤ 60, 61-90, > 90 dias, respectivamente). Método Conclusões:Este estudo multicêntrico demonstrou que o encaminhamento tardio das crianças portad...
