Ultrasound-guided Biliary Drainage Improving Prognosis in the Frail and High Risk Elderly Patients

Plain-language summary

Acute biliary tract infection is a kind of disease caused by bacteria of biliary tract infection, mainly including acute cholecystitis and acute cholangitis, especially acute obstructive suppurative cholangitis (AOSC),which can lead to septic shock and multiple organ failure,and the mortality rate is high in the frail and high risk elderly patients. Our study involved bedside ultrasoundguided real-time biliary drainage by emergency surgeon in the frail and high risk elderly patients with severe acute suppurative infection of biliary tract,the goal of this clinical trial is to learn if it can improve patient prognosis and reduce mortality. Participants will be divided into experimental group (emergency bedside ultrasound group) and controlgroup (traditional ultrasound group). The experimental group will be performed gallbladder or bile duct puncture under the guidance of emergency bedside ultrasound, while the control group will be performed puncture by traditional appointment ultrasound, The accuracy of ultrasound diagnosis, the total time of examination and puncture treatment,complications, hospitalization time and expenses will be compared between the two groups.
