Summary
This case report details a rare type Vb double common bile duct (DCBD) in a young cholangiocarcinoma patient. Prompt diagnosis and stenting of both ducts resolved biliary obstruction, enabling chemotherapy continuation.
Area of Science:
- Gastroenterology
- Surgical Anatomy
- Medical Imaging
Background:
- Double common bile duct (DCBD) is a rare biliary anomaly, with Type Vb representing a particularly infrequent subtype.
- DCBD is associated with an increased risk of biliary and gastrointestinal malignancies.
Observation:
- A 28-year-old female with intrahepatic cholangiocarcinoma presented with worsening jaundice despite a percutaneous transhepatic cholangiography (PTC) drain.
- Diagnostic imaging revealed a rare Type Vb DCBD, indicating incomplete biliary drainage.
Findings:
- The patient was diagnosed with Type Vb DCBD, a rare anatomical variation.
- Placement of metal stents in both common bile ducts effectively resolved the biliary obstruction and jaundice.
Implications:
- This case underscores the importance of considering DCBD in young cancer patients with unexplained jaundice.
- Advanced imaging like MRCP is crucial for diagnosing DCBD, and dual stenting is essential for managing biliary obstruction in these cases.

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

117
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.
