Background: The 2022 Society of Radiologists in Ultrasound (SRU) consensus conference recommendations support less-aggressive management of small gallbladder polyps on ultrasound versus earlier approaches and may help standardize polyp evaluation by radiologists. Objective: To assess radiologists' interreader agreement in applying the SRU recommendations for management of incidental gallbladder polyps on ultrasound. Methods: This retrospective study included 105 patients (median age, 52 years; 75 women, 27 men) with a gallbladder polyp on ultrasound (without features highly suspicious for invasive or malignant tumor) who underwent cholecystectomy between January 1, 2003 and January 1, 2021. Ten abdominal radiologists independently reviewed ultrasound examinations and, using SRU recommendations, assessed one polyp per patient for risk category (extremely low-risk, low-risk, or indeterminate risk) and possible recommendation for surgical consultation. Five radiologists were considered less-experienced (<5 years), and five more-experienced (≥5 years). Interreader agreement was evaluated. Polyps were classified pathologically as nonneoplastic or neoplastic. Results: For risk category assignments, interreader agreement was substantial among all readers (k=0.710), less-experienced readers (k=0.705), and more-experienced readers (k=0.692). For surgical consultation recommendations, interreader agreement was substantial among all readers (k=0.795) and more-experienced readers (kappa=0.740), and almost perfect among less-experienced readers (k=0.811). Of ten readers, a median of 5 (IQR, 2-8), 4 (IQR, 2-7), and 0 (IQR, 0-0) classified polyps as extremely low risk, low risk, and indeterminate risk, respectively. Across readers, the fraction of polyps classified as extremely low risk ranged from 32-72%, as low risk from 24-65%, and as indeterminate risk from 0-8%. Of ten readers, a median of 0 (IQR, 0-1) recommended surgical consultation; the fraction of polyps receiving a surgical consultation recommendation ranged from 4-22%. A total of 102/105 polyps were nonneoplastic; 3/105 were neoplastic (all benign). Based on readers' most-common assessments for the nonneoplastic polyps, the risk category was extremely low risk in 53, low risk in 48, and indeterminate risk in 1; surgical consultation was recommended in 16. Conclusion: Ten abdominal radiologists showed substantial agreement for polyp risk categorizations and surgical consultation recommendations, although areas of reader variability were identified. Clinical Impact: The findings support overall reproducibility of the SRU recommendations, while indicating opportunity for improvement.
