          Abstract

          Background

          The cystic dilatation of the biliary tract is a rare disease and uncertain origin. It is recognized more frequently in children; however, its incidence comes increasing in adults, representing 20% of the cases.

          Aim

          To evaluate morbimortality rates, evolution and handing of patients with cystic dilatation bile ducts in adults.

          Methods

          Were evaluated, retrospectively, five adults who had the diagnosis of choledochal cyst and that had been submitted to some surgical procedure.

          Results

          Abdominal pain was the commonest complain to all patients. Jaundice was present in 80%. Ultrasound scanning was done in all the cases as initial examination. CT scan, magnetic resonance imaging and endoscopic retrograde cholangiopancreatography were also done in some patients; however, the diagnosis was established intra-operatively in all cases. The cyst resection with reconstruction of the biliary tract was done in 60%; the cystojejunostomy in 20%; and in 20% biliary tract drainage.

          Conclusions

          Biliary tract cystic dilatation is a rare disease. However, its incidence is increasing in the adult population, so, it must be thought as differential diagnosis when facing obstructive jaundice.

          Racional

          A dilatação cística da via biliar é uma patologia rara e de origem incerta. É diagnosticada mais frequentemente em crianças, porém sua incidência vem aumentando em adultos, representando 20% dos casos.

          Objetivo

          Demonstrar a experiência dos autores no tratamento cirúrgico, e no manejo da evolução, dos pacientes com dilatação cística das vias biliares.

          Métodos

          Foram avaliados, retrospectivamente, cinco adultos que tiveram o diagnóstico de cisto de colédoco e que foram submetidos a algum procedimento cirúrgico no Hospital da Restauração, PE, entre março de 2003 e junho de 2004.

          Resultados

          Dor abdominal foi a queixa comum a todos os pacientes. Icterícia esteve presente em 80% dos casos. A ultrassonografia foi realizada em todos os casos como exame inicial. Tomografia computadorizada, ressonância magnética e colangiopancreatografia retrógada endoscópica também foram realizadas em alguns pacientes, porém o diagnóstico foi estabelecido no intraoperatório em todos os casos. O tratamento cirúrgico variou de acordo com a experiência do cirurgião e o quadro clínico do paciente. A ressecção do cisto com reconstrução da via biliar foi realizada em 60%, a cistoduodenostomia em 20% e a drenagem da via biliar em 20% dos casos.

          Conclusões

          A dilatação cística da via biliar é doença rara, principalmente em nosso meio. Porém, sua incidência vem aumentando na população adulta, devendo estar sempre presente no diagnóstico diferencial das icterícias obstrutivas.

          Congenital bile duct cysts: Classification, operative procedures, and review of thirty-seven cases including cancer arising from choledochal cyst.

          Congenital bile duct cysts are observed in any part of the bile duct from the liver to the duodenum. Reports of cases of cancer arising from it are increasing. Excision of the choledochal cyst seems to be the treatment of choice and partial resection of the intrahepatic cyst followed by intrahepatic cystoenterostomy at the porta hepatis is necessary for type IV-A cysts.

              Epidemiology, presentation, diagnosis, and outcomes of choledochal cysts in adults in an urban environment.

              Choledochal cysts (CDC) are rare congenital cystic lesions of the biliary tract. In North America the incidence of CDC is estimated as 1/150,000; it is not clear that the disease pattern in North America is similar to that in Asia. Retrospective chart review. Statistical analysis was under taken using Fisher's exact test. Presentation, epidemiology, diagnosis, and outcome were evaluated in 51 patients with CDC. Malignant transformation was identified in 4 patients presenting uniformly with jaundice (P = .027). Type 4a cysts (54.9%) were the most common cyst identified. Four (14%) type IVa and two (13%) type I cysts developed postoperative stricture. No patient developed cholangiocarcinoma after complete resection of their cyst. Types I and IVa cysts can be treated similarly with excellent outcome. However, our observation of a high proportion of type 4a cysts may represent a specific North American pattern of this disease requiring a re-evaluation of the classification system.
