What are the signs of infection after stent placement in ERCP?

After ERCP stent placement, infection is a potential complication that requires prompt attention. Common infections include cholangitis (infection of the bile ducts) or sepsis if the infection spreads systemically. Here are the key signs and symptoms of infection to watch for:

1. Fever

• Sudden onset of fever: A fever higher than 100.4°F (38°C) is a common early sign.

• May be accompanied by chills or rigors, indicating systemic infection.

2. Jaundice

• Yellowing of the skin or eyes due to bile duct obstruction or infection.

• May worsen if the stent becomes occluded or if the infection is severe.

3. Abdominal Pain

• Pain in the upper right quadrant or center of the abdomen.

• May radiate to the back or right shoulder.

4. Nausea and Vomiting

• Often associated with bile duct infection or obstruction.

• Can lead to dehydration and worsen symptoms.

5. Fatigue and Malaise

• A general sense of illness or feeling unwell.

• Often accompanies fever and systemic infection.

6. Changes in Stool and Urine

• Dark urine: Indicates bile accumulation in the bloodstream.

• Pale or clay-colored stools: Sign of blocked bile flow into the intestines.

7. Elevated Heart Rate and Low Blood Pressure

• Tachycardia and hypotension can occur if the infection progresses to sepsis.

• Requires immediate medical attention.

8. Laboratory and Imaging Indicators

• Elevated white blood cell (WBC) count: Suggestive of infection.

• Elevated liver enzymes: Particularly alkaline phosphatase (ALP) and bilirubin, indicating bile duct involvement.

• Imaging (e.g., ultrasound or CT): May show bile duct dilation or stent blockage.

When to Seek Immediate Medical Attention

• Persistent high fever or worsening symptoms.

• Severe abdominal pain.

• Symptoms of sepsis:

• Confusion or mental changes.

• Rapid breathing or shortness of breath.

• Profound weakness or drowsiness.

Preventive Measures

• Prophylactic antibiotics: Often prescribed before and after the procedure to reduce the risk of infection.

• Follow-up care: Routine imaging or tests to monitor stent position and function.

• Hydration and hygiene: Maintaining good hydration and promptly reporting symptoms.

Conclusion

Signs of infection after ERCP stent placement include fever, jaundice, abdominal pain, and systemic symptoms like fatigue or low blood pressure. Recognizing these signs early and seeking medical attention can prevent complications like sepsis or stent failure.
