Summary
This case study highlights early mucosal bile duct carcinoma, a rare cancer. Percutaneous transhepatic cholangioscopy (PTCS) proved crucial for diagnosing this superficial spread of papillary adenocarcinoma.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Diagnostic Imaging
Background:
- Gallstone pancreatitis can present with symptoms mimicking biliary obstruction.
- Early detection of bile duct carcinoma is critical for successful treatment.
- Mucosal bile duct carcinoma with superficial spread is a rare entity.
Observation:
- A 69-year-old male with gallstone pancreatitis presented with abdominal pain, fever, and jaundice.
- Endoscopic retrograde cholangiography (ERC) showed a suspicious lesion in the common bile duct (CBD).
- Percutaneous transhepatic cholangioscopy (PTCS) revealed a papillary tumor with superficial spread in the CBD.
Findings:
- Biopsies confirmed papillary adenocarcinoma confined to the mucosal layer.
- PTCS accurately assessed the extent of the superficial tumor.
- Surgical resection achieved tumor-free margins.
Implications:
- PTCS offers significant diagnostic advantages for early mucosal bile duct carcinoma.
- This case underscores the importance of advanced endoscopic techniques in diagnosing rare biliary cancers.
- Further research into PTCS for early detection of biliary tract cancers is warranted.
