Patients were classified into three groups based on treatment strategy: A (consistent with TG18 recommendations,\n n<\/jats:italic>\n \u2009=\u2009206), B (more aggressive than TG18 recommendations,\n n<\/jats:italic>\n \u2009=\u2009135), and C (more conservative than TG18 recommendations,\n n<\/jats:italic>\n \u2009=\u2009120). Multivariate analyses were performed to identify potential surgical complication predictors.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Among Grade I\/II AC patients, overall complication rates in Groups A, B, and C were 16.4%, 34.0%, and 8.3%, respectively (A vs. B:\n p<\/jats:italic>\n \u2009<\u20090.001, A vs. C:\n p<\/jats:italic>\n \u2009=\u20090.052) and major complication rates were 3.1%, 9.4%, and 5.0%, respectively (A vs. B:\n p<\/jats:italic>\n \u2009=\u20090.029, A vs. C:\n p<\/jats:italic>\n \u2009=\u20090.382). Laparoscopic approaches were most frequent in Group C (A, 59.7% vs. B, 22.6% vs. C, 96.6%,\n p<\/jats:italic>\n \u2009<\u20090.001). Anticoagulant\/antiplatelet therapy independently predicted major complications (odds ratio 3.10,\n p<\/jats:italic>\n \u2009=\u20090.023).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n In the present trial, treatment for AC was consistent with TG18 recommendations in 45% of patients. Compared with TG18\u2010aligned treatment, more conservative treatment was associated with comparable morbidities, while more aggressive treatment was associated with a higher incidence of major
