Further Inpatient Care
- Patients with bile duct strictures (biliary strictures) who develop obstructive jaundice complicated by fever, infection, or duodenal obstruction are often admitted for urgent inpatient treatment of obstruction and/or infection.
- Patients presenting with ascending cholangitis may need to be admitted to the intensive care unit, especially if they have altered mental status and hypotension. These patients should be started on broad-spectrum antibiotics with good gram-negative and anaerobic coverage.
- In addition, urgent drainage and decompression of the biliary tree may be required when an appropriate response to antibiotic therapy is not achieved.
- Patients with bile duct strictures (biliary strictures) amenable to endoscopic therapy can be treated in an inpatient or outpatient setting. Those requiring surgery generally have a longer hospital stay, especially in the postoperative period.
Further Outpatient Care
- Patients with bile duct strictures (biliary strictures) with percutaneous drains should have their catheters flushed with 5-10 mL of saline once or twice every day to prevent catheter blockage.
- Patients should be monitored closely for recurrence of cholangitis and obstructive jaundice, which can occur if the biliary drainage catheters or stents are occluded or if they migrate.
- Those treated with biliary stenting with plastic stents or balloon dilatation of bile duct strictures (biliary strictures) need periodic follow-up with a gastroenterologist or interventional radiologist for stent changes and periodic stricture dilatation.
- Patients with external biliary drains should also seek follow-up with an interventional radiologist for catheter exchanges every 2-3 months for internalization of drains.
- Those with a malignant obstruction treated with metallic endoprosthesis should be monitored with periodic liver function testing. Progressively abnormal liver function tests suggest stent dysfunction.
Transfer
- Management of bile duct strictures (biliary strictures) is a complex problem requiring a multidisciplinary approach. The patient should be in a specialized center where expertise in diagnostic and therapeutic ERCP and biliary interventional radiology is available. Surgical therapy should also be performed in centers with staff experienced in performing hepatobiliary and pancreatic surgery.
Complications
- Complications of bile duct strictures (biliary strictures) include development of stones in the gallbladder and bile ducts proximal to the stricture, pyogenic liver abscess due to recurrent episodes of ascending cholangitis, secondary biliary cirrhosis, and weight loss and malnutrition from steatorrhea with fat-soluble vitamin deficiency.
Prognosis
- The prognosis for patients with benign bile duct strictures (biliary strictures) is good. Patients who develop symptoms of biliary obstruction do well after surgical or endoscopic therapy.
- Conversely, patients with HIV cholangiopathy or malignant biliary obstruction usually present at a late stage with widespread disease, and they generally have a dismal prognosis.
Patient Education
- Patients with biliary stents should be educated regarding how to recognize the symptoms of biliary obstruction and cholangitis that indicate blocked stents. Those with external drains should be taught how to flush their catheters until the catheters are internalized.
- Patients with alcoholic chronic pancreatitis may benefit from counseling and alcohol abuse rehabilitation.
