Endoscopic management of choledochal cyst.

BACKGROUND

Choledochal cyst is an uncommon anomaly of the biliary tract. Experience with this disorder, with emphasis on the role of ERCP in management, is presented.

METHODS

All pertinent data for 13 patients with choledochal cyst seen between 1987 and 1998 were reviewed, retrospectively.

OBSERVATIONS: Cholangitis, either alone or associated with other findings, was the main presenting feature (69.23% of patients). Bilobar Caroli's disease was the most common cyst type (46.15% of patients). ERCP was diagnostic alone in 46.15% of patients and therapeutic in 53.85%.

CONCLUSIONS

Choledochal cyst is a complex condition that requires early diagnosis. Long-term management remains controversial, and guidelines for treatment require revision. Whether interventional ERCP will obviate the need for surgery or alter the malignant potential of the disorder remains uncertain.
