Summary

This case study highlights diagnosing extrahepatic cholangiocarcinoma with superficial spread. Accurate preoperative diagnosis using cholangioscopy is crucial for successful tumor resection.

Background:

Cholangiocarcinoma, a bile duct cancer, can present as raised or infiltrative types.
Superficial spread along the mucosa can occur, complicating diagnosis and treatment.
Extrahepatic cholangiocarcinoma arises outside the liver's main bile ducts.

Observation:

A 62-year-old male presented with an elevated lesion in the bile duct.
Cholangiography revealed extensive irregularity surrounding the elevated lesion.
Percutaneous transhepatic cholangioscopy identified the full tumor extent.

Findings:

The cholangiocarcinoma exhibited extensive superficial spread.
Radical resection was achieved without the need for liver resection.

Microscopic examination confirmed tumor-negative surgical margins.

Implications:

Accurate preoperative staging of superficial spread is vital for cholangiocarcinoma.
Cholangioscopy and biopsy are essential for defining resection margins.
This approach enables successful radical resection, potentially avoiding extensive surgery.
