Among 3426 pregnant patients with AC and 1-year follow-up, 1182 (34.5%) underwent cholecystectomy during the pregnancy (684 [41.7%] presenting with AC in T1, 404 [40.4%] in T2, and 94 [12.0%] in T3). Acute cholecystitis during pregnancy, irrespective of treatment, was associated with higher odds of APO compared with no AC during pregnancy across all trimesters (odds ratio [OR], 1.69 [95% CI, 1.54-1.85]). Compared with nonoperative management, receipt of surgery was associated with lower odds of APOs across all trimesters (OR, 0.75 [95% CI, 0.63-0.87]), in T1 (OR, 0.81 [95% CI, 0.66-1.00]), in T2 (OR, 0.71 [95% CI, 0.50-1.00]), and in T3 (OR, 0.45 [95% CI, 0.28-0.70]).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"ab-soi230084-10\">\n                    <jats:title>Conclusions and Relevance<\/jats:title>\n                    <jats:p>In this study, cholecystectomy was associated with lower risk of APO in patients with AC across all trimesters, with the greatest benefit in T3. However, only 34.5% overall and 12.0% of patients in T3 had a cholecystectomy. These findings support guidelines recommending cholecystectomy during pregnancy and should inform decision-making discussions. Greater guideline adherence and surgery use, especially in T3, may represent an opportunity to improve outcomes for pregnant people with AC.<\/jats:p>\n
