Extrahepatic bile ducts are small tubes that carry bile outside of the liver. They are made up of the common hepatic duct (hilum region) and the common bile duct (distal region). Bile is made in the liver and flows through the common hepatic duct and the cystic duct to the gallbladder, where it is stored.

Abstract

Cholangiocarcinoma (CCA) are sub-divided into intrahepatic (iCCA) or extrahepatic (eCCA). eCCA are further subdivided into perihilar (pCCA) and distal (dCCA). Current and previous versions of the WHO International Coding of Disease and Oncology classifications (ICD) have separate topography codes for iCCA and eCCA, but none for pCCA.

Introduction

Cholangiocarcinoma (CCA) constitutes a group of epithelial malignancies arising from the biliary tree. They are the most common biliary malignancy, and second most common hepatobiliary malignancy, accounting for 10–15% of the total incidence [ 1, 2 ].

Methods

A retrospective clinical review of cases coded as hepatobiliary carcinoma using ICD-10 criteria was performed at three regional UK HPB Centres: Imperial College Healthcare NHS Trust (ICHT) covering West and North West London, University College London Hospitals NHS Foundation Trust (UCHT) covering North London and Aintree University Hospital NHS Foundation Trust (AUHT) covering the Merseyside region.

Results

A total of 744 CCA cases were assessed from across all three centres. 119 were excluded due to clinical data being insufficient to confidently confirm the diagnosis and/or location of the tumour. Of the 625 cases that were fully reviewed, 226 cases were coded as C22.1/iCCA, of which 98 cases (43%) were deemed to have been correctly coded.

Discussion

Our study confirmed widespread misclassification of CCA coding in a large patient population across three independent HPB centres both inside and out of London: over 90% of cases verified as pCCA were incorrectly coded as C22.1/iCCA.
