Ultrasound is the primary investigation. Cholecystectomy is recommended for polypoid lesions of 10 mm or more (strong recommendation, low-quality evidence), for symptomatic polyps, and for 6 to 9 mm polyps with a risk factor: age over 60, primary sclerosing cholangitis, Asian ethnicity, or a sessile lesion including focal wall thickening over 4 mm.\n\nPolyps of 6 to 9 mm without risk factors, or 5 mm or less with risk factors, get ultrasound at 6 months, 1 and 2 years and are discharged if they have not grown; 5 mm or less without risk factors need no follow-up. Growth to 10 mm means surgery; growth of 2 mm or more within two years prompts multidisciplinary discussion; a polyp that disappears ends monitoring.","asOf":"2026-09-24","links":[{"label":"Eur Radiol 2022","url":"https://doi.org/10.1007/s00330-021-08384-w"},{"label":"PubMed","url":"https://pubmed.ncbi.nlm.nih.gov/34918177/"}],"tags":["gallbladder-evidence"],"related":[],"cancers":["gallbladder"],"sections":[],"technologies":["ultrasound"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":["gallbladder-polyp","screening","overdiagnosis"],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"journal":"European Radiology","year":2022,"doi":"10.1007/s00330-021-08384-w","pmid":"34918177","authors":"Foley KG, Lahaye MJ, Thoeni RF, et al.","paperType":"guideline","findings":["Cholecystectomy for polypoid lesions of 10 mm or more (strong recommendation, low-quality evidence).","Cholecystectomy for 6 to 9 mm lesions with a risk factor: age over 60, primary sclerosing cholangitis, Asian ethnicity, sessile shape or wall thickening over 4 mm.","Ultrasound at 6 months, 1 year and 2 years for 6 to 9 mm lesions without risk factors and 5 mm or smaller lesions with them; no follow-up for 5 mm or smaller lesions without risk factors.","Growth to 10 mm: surgery; growth of 2 mm or more within two years: multidisciplinary review."],"whatItMeans":"This is the polyp pathway UK radiologists and surgeons follow (a UK author, Foley, leads it).
