A biliary endoprosthesis functioning after six years

Area of Science:

• Gastroenterology and Hepatology
• Medical Devices and Technology

Background:

• Biliary endoprostheses are used for managing common bile duct stones, offering a non-surgical option for high-risk patients.
• These stents typically have a functional lifetime of approximately 7 months and often require replacement.
• Recent evidence suggests that biliary endoprostheses may be functioning for extended periods.

Purpose of the Study:

• To report a case of a biliary endoprosthesis functioning significantly beyond its typical lifespan.
• To highlight the potential for extended functionality of biliary endoprostheses in specific patient populations.

Main Methods:

• Case presentation of an 85-year-old asymptomatic female patient.
• Review of the patient's medical history and imaging regarding a biliary endoprosthesis.
• Literature search to compare the duration of stent function with previously reported cases.

Main Results:

• The patient presented with an asymptomatic biliary endoprosthesis that had been in place for 6 years.
• This duration of function is believed to be the longest reported in the medical literature.
• The patient remained asymptomatic throughout the 6-year period with the indwelling stent.

Conclusions:

• Biliary endoprostheses can potentially function for much longer than the conventionally accepted 7-month period.
• This case underscores the need for further research into factors influencing the longevity of biliary endoprostheses.
• Extended stent functionality may have implications for patient management and reduce the need for repeat interventions.
