title: [Biliary atresias operated with favourable results: predictable outcome].
abstract: Since 1975, our experience in the treatment of biliary atresia with Kasai's technique has improved little by little, achieving 65% favourable outcome in the last five years. We define "good results" as the complete restoration of biliary flow and normalization of bilirrubin levels. The long-term evolution of these good results can be diverse. The objective of the present work is to analyze the outcome of patients in our series in whom a favourable initial response was achieved, as well as evaluating their present situation and future perspectives. The authors present a total of 17 patients operated by Kasai's technique since 1985, that constitutes the group with good results in our series. The controls were based on general analysis, liver function and periodic ultrasound explorations. All received a standardized medical treatment consisting of vitamin supplements (A, D3, E, K) minerals (zinc, calcium, phosphate, iron) ursodexoxicolic acid, luminal,as well as close control of calorie intake. In two patients the levels of bilirrubine were progressively increased with time, stabilizing at between 5/6 mgs/100 ml, with progressive hepatic hardening, appearance of splenomegalia, indirect signs of portal hypertension and a slight deterioration of hepatic function. One received a transplant at age 12 with Quick levels below 50%. The other, aged 16, continues with an acceptable hepatic function and good quality of life under recommendation of transplant. Eleven patients with ages ranging from fourteen months to seventeen years presented slight and firm hepatomegalia, moderate portal hypertension, GOT 71 +/- 8 mg/100 ml, GPT 97 +/- 11 mg/100 ml and normal bilirrubine levels. From this group, 3 patients, all under five years of age, experienced bleeding from esophageal varices which were controlled by sclerosis and medical treatment (propanolol and isosorbide dinitrate). Recently, one three year-old patient developed a hepatocarcinoma of rapid, mortal evolution. Since then, the determination of alfa-feto protein in follow-up controls has been introduced. Four other patients of 5, 6, 14, 16, years of age are completely assymptomatic with an excellent clinical evolution. In our experience,the patients that overcome the third year after surgery without serious complications seem destined to reach puberty with a good quality of life. However, some cases show signs of hepatic fibrosis and portal hypertension, 77% in our series. Only 23% of patients with a favorable initial evolution appear to present a complete normalization of their hepatic lesion in the long term.
