What is a Gallbladder Polyp?
Mucosal projection into the gallbladder lumen. Ultrasound measures size and detects concerning features.
Imaging Appearance
- Sessile or pedunculated wall lesion
- No acoustic shadowing (distinguishes from stones)
- Vascular stalk may be seen on Doppler
Clinical Significance
- ＜6 mm in average-risk patients usually observed
- ≥10 mm or rapid growth may prompt cholecystectomy
- Primary sclerosing cholangitis or Asian ethnicity increases malignancy risk
Symptoms
- Often asymptomatic; biliary colic if associated with stones
Diagnosis
- Ultrasound; follow-up interval based on size/risk
- Labs: liver enzymes if biliary symptoms
Treatment
- Observation with interval ultrasound
- Cholecystectomy for high-risk size/features
Prognosis
- Most remain benign and stable
What Should You Do?
- Know polyp size and recommended follow-up schedule.
- Seek care for RUQ pain, fever, or jaundice.
- Discuss surgery if polyp ≥10 mm or growing.
