Small Asymptomatic Gallbladder Polyps (<10 mm)
Ursodeoxycholic acid (UDCA) is not recommended for treating incidentally detected, asymptomatic gallbladder polyps measuring <10 mm. [1]
Pathology and Malignancy Risk Basis
Polyps <10 mm are predominantly nonneoplastic lesions, most commonly benign cholesterol polyps, and have negligible (if any) risk of dysplasia or malignancy. [1]
Guideline-Recommended Management Strategy
Management for gallbladder polypoid lesions <10 mm with no concerning features is risk-stratified by polyp size and patient risk factors. [1]
Follow-Up and When Cholecystectomy Is Considered
For patients with low-risk lesions, follow-up ultrasound is generally reserved for specific size and risk-factor combinations, with cholecystectomy advised when polyps reach threshold sizes (for example, ≥10 mm) or when concerning growth occurs. [2]
Role of Medical Therapy With UDCA
No major guideline recommends UDCA for treatment of small (<10 mm) asymptomatic gallbladder polyps. [1]
Rationale for Not Using UDCA
UDCA is used to dissolve radiolucent, noncalcified gallbladder stones, not to treat gallbladder polypoid lesions. [3]
Targets of Therapy
The guideline goal for small asymptomatic gallbladder polyps is appropriate surveillance and surgical risk management when threshold criteria are met, not chemoprevention. [1]
