ERCP treatment of obstructive jaundice caused by hydatid cyst in extrahepatic ducts 13 years after liver hydatid endocystectomy. A case report.

INTRODUCTION

Hydatid disease affects most commonly the liver, and complications with the rupture into the biliary tree develop in approximately one-fourth of the cases. Moreover, primary hydatid cysts of the biliary tract have been reported.

PRESENTATION OF CASE: We report an extremely rare case of obstructive jaundice caused by hydatid cyst in extrahepatic ducts 13 years after liver hydatid endocystectomy treated by Endoscopic retrograde cholangiopancreatography (ERCP). A 28-year-old male patient who had undergone surgical treatment - removal of liver hydatid cyst 13 years earlier, presented with signs of obstructed jaundice, confirmed with blood tests results and magnetic resonance cholangiopancreatography (MRCP). Actually, there were no pathological changes detected in the hepatic parenchyma, but the intrahepatic and extrahepatic bile ducts were dilated. ERCP was performed and the entire hydatid material was evacuated and washed out into the gastrointestinal tract. In addition, after laparoscopic cholecystectomy, hydatid cysts were also confirmed in the gallbladder.

DISCUSSION: Generally, the obstructive jaundice caused by hydatid cyst in the extrahepatic ducts can also be caused by the rupture of the liver hydatid cyst in the biliary tract, or by primary hydatid cyst in the biliary tract. The ERCP plays a key role in the diagnosis and the treatment of this pathology.

CONCLUSION

The ERCP, has now become an important diagnostic and therapeutic procedure in management of primary extrahepatic hydatid cysts and of complicated liver hydatid cysts.
