Number of patients with complete expulsion of gallbladder sludge after three days of intervention
Determined by ultrasound examination before and after the intervention to assess whether gallbladder sludge has been fully expelled
2）Number of patients with complete expulsion of gallbladder sludge after six days of intervention
Determined by ultrasound examination before and after the intervention to assess whether gallbladder sludge has been fully expelled
Gallbladder Volume
Measured by ultrasound (L × W × D × 0.52)
Gallbladder Wall Thickness
Measured by ultrasound, accurate to 0.1 mm
Serum bilirubin
Determined by lab examination within 3.4-17.1μmol/L
Presence of Abdominal Pain Post-Intervention
If abdominal pain is present, it will be assessed using the Numerical Rating Scale (NRS) within 0-10, The higher the score, the more serious it is
