    Abstract:
    Follow-up results were analyzed to evaluate the surgical managements of pancreatic complications such as pancreatitis and protein plug formation in patients with choledochal cysts. Sixty-two patients with choledochal cysts treated between 1976 and 1999 were reviewed. Twenty-four were children and 38 were adults. Fifty-four patients showed primary cases. Cyst excision and hepaticoenterostomy were finally performed in 56 patients. Surgical sphincteroplasty or endoscopic sphincterotomy was performed to prevent recurrent protein plugs in six patients. The follow-up period was 8.1 +/- 6.1 years. Acute pancreatitis and protein plug formation was observed in 18 (33.3%) and 11 (20.4%) of 54 patients showing primary cases, respectively. Both acute pancreatitis and protein plug formation were observed more frequently in children from 1 to 15 years of age (70.6% and 41.2%, respectively) than in adults (18.6% and 12.5%, respectively). Acute pancreatitis and/or protein plug formation developed in four (57.1%) of seven patients who underwent cystenterostomy. Protein plug formation in the residual cyst after cyst excision was observed in two patients, one of whom had undergone sphincteroplasty. Diabetes mellitus due to chronic pancreatitis developed in one patient who was diagnosed late. No other pancreatitis or protein plug recurred postoperatively in this series. Our results suggested that cystenterostomy did not resolve pancreatic complications of choledochal cysts, and that surgical sphincteroplasty was ineffective in preventing the recurrent protein plug formation in the residual duct. In conclusion, complete cyst excision and an early diagnosis are necessary to prevent the development of chronic or recurrent pancreatitis after surgery.
