In recent years, an accepted operative procedure for choledochal cyst is excision of the cyst with hepaticoenterostomy. However, in 1971, before the pathological problem of a long common channel were recognized, we saw one case in which biliary reconstruction could be achieved by hepaticocholedochostomy after excision of a choledochal cyst. In 1989, 18 years after surgery, we had the opportunity to examine the patient and perform ERCP and echography. The patient has had no symptoms of pancreatitis or jaundice. The long common channel persists, but no dilatation, stenosis, stones, or malignancy, were found. This unique experience led us to two conclusions : 1. Stenosis is an important etiological factor in choledochal cysts. 2. Pancreatitis may not occur when the gallbladder is absent, when pancreatic duct pressure is always higher than biliary pressure.
