Abstract

Introduction:

Choledochal cyst (CDC) is often associated with intrahepatic stones (IHSs) in children which necessitate their removal during excision. The endoscopic equipment needed for their clearance such as paediatric flexible cholangioscope and other advanced modalities are not freely available in resource-poor setups. We describe per-operative modified rigid cholangioscopy using rigid paediatric cystoscope for stone removal during open CDC excision.

Methods:

All children with CDC presenting with IHSs between January 2015 and December 2017 were included in the present study. IHSs were diagnosed by ultrasound/magnetic resonance cholangiopancreatography (MRCP). In these patients, after cyst excision by open technique, a 9 Fr paediatric cystoscope with 4 Fr working channel was inserted into the common hepatic duct for visualisation and clearance of stones from (intrahepatic bile ducts). Follow-up was done using liver function tests, ultrasound and MRCP (if needed). Patients underwent three monthly liver function test and ultrasound and if needed MRCP.

Results:

Six cases of CDC presenting with IHS were managed, and one case with post-R-en-Y IHS was treated with this technique. Rigid paediatric cystoscope with working channel and forceps was used. All cases were successfully managed, and one case was found to have intrahepatic duct stenosis was dilated.

Conclusion:

Per-operative rigid endoscopy using paediatric cystoscope is an easily available tool in most of the setups for the management of IHS associated with CDC in children.
