Clinical Analysis of Choledochal Cyst
Abstract
-
BACKGROUND/AIMS: Choledochal cyst is frequently associated with many complications and malignant changes. The aims of this study were to analyze its clinical characteristics and to confirm whethe the excision of cyst is appropriate treatment.
METHODS
We reviewed the medical records of 28 patients with choledochal cyst who were treated surgically at St. Benedict hospital from January 1988 through December, 1997.
RESULTS
This disease was more common in female patients than in male patients. The symptoms and signs were abdominal pain, jaundice, indigestion, fever and mass Endoscopic retrograde cholangiopancreatography has been the most accurate diagnostic method for choledochal cyst. When the patients were classified into 4 groups according to the Todani' s classifi cation, type I cyst was the most common (71.4%) and followed by type IV (14.3%), type III (10.7% and type II (3.6%) in order. Increased amylase level in the bile juice was found in 10 cases. The associated disorders such as biliary stones, cholangitis and pancreatitis were observed. Gallbladder cancer was found in one patient. Twenty-two cysts were excised completely and Roux-en-Y hepati cojejunostomy was performed in 21 of them. The operative mortality was 7.1%.
CONCLUSIONS
The choledochal cyst should be excised as completely as possible to minimize its associated complications such as recurrent cholangitis, pancreatitis and malignant change.
