From the Guidelines
The management of this 47-year-old patient with chronic left upper quadrant pain, biliary sludge, mid CBD dilation with distal stricture, and normal liver function tests likely represents a case of anomalous pancreaticobiliary junction (APBJ), and the patient should undergo regular surveillance with imaging (MRI/MRCP) every 1-2 years to monitor for recurrence of stricture or development of malignancy, as recommended by recent guidelines 1. The patient's presentation is consistent with APBJ, a congenital anomaly where the pancreatic and biliary ducts join outside the duodenal wall, creating a long common channel that allows pancreatic enzymes to reflux into the biliary system, leading to chronic inflammation, stricture formation, sludge accumulation, and recurrent pain, as described in the guidelines 1. The ERCP with dilation of the CBD stricture and removal of sludge/debris was an appropriate initial management, which successfully resolved the pain, and the use of ursodeoxycholic acid (10-15 mg/kg/day) may be prescribed to prevent sludge reformation, as suggested by the guidelines 1. The patient should be counseled about symptoms that warrant immediate evaluation, including recurrent pain, jaundice, or fever, and the importance of long-term surveillance to monitor for the development of malignancies, as recommended by the guidelines 1. Key points to consider in the management of this patient include:
- Regular surveillance with imaging (MRI/MRCP) every 1-2 years to monitor for recurrence of stricture or development of malignancy
- Use of ursodeoxycholic acid (10-15 mg/kg/day) to prevent sludge reformation
- Counseling the patient about symptoms that warrant immediate evaluation, including recurrent pain, jaundice, or fever
- Long-term surveillance to monitor for the development of malignancies, as recommended by the guidelines 1.
From the Research
Management of Chronic Abdominal Pain with Bile Duct Abnormalities
- The patient's symptoms and test results, including sludge on CT and MRCP showing mid CBD dilation and distal CBD stricture, and normal LFTs, suggest a possible choledochocele or other bile duct abnormality 2.
- The patient underwent ERCP with dilation of the CBD stricture and removal of sludge/debris, which resulted in resolution of pain.
- The presence of an anomalous pancreaticobiliary junction may also be a contributing factor to the patient's symptoms.
Role of Ursodeoxycholic Acid
- Ursodeoxycholic acid (UDCA) has been shown to be effective in improving liver tests and reducing biliary complications in patients with primary biliary cirrhosis and primary sclerosing cholangitis 3, 4, 5.
- However, the patient's normal LFTs and lack of diagnosis of primary biliary cirrhosis or primary sclerosing cholangitis make it unclear whether UDCA would be beneficial in this case.
- UDCA has also been shown to reduce the incidence of biliary sludge and casts after liver transplantation 6, but its role in preventing biliary complications in patients with anomalous pancreaticobiliary junction is not well established.
Further Evaluation and Management
- Further evaluation and management of the patient's condition should be guided by a gastroenterologist or hepatologist, taking into account the patient's symptoms, test results, and medical history.
- Regular follow-up and monitoring of the patient's condition may be necessary to prevent future biliary complications and ensure optimal management of the anomalous pancreaticobiliary junction.
