Multivariate analysis also demonstrated that operative time(p=0.003, OR 1.006, 95%CI 1.002-1.010)and CONUT score(p=0.025, OR 1.508, 95%CI 1.053-2.161)were significant risk factors for SSI development. CONCLUSIONS The CONUT score was identified as a significant preoperative risk factor for SSI after rectal cancer surgery in both the univariate and multivariate analyses. Therefore, the preoperative evaluation using the CONUT score may be useful for predicting the risk of SSI in patients undergoing rectal cancer surgery.Case 1 A man in his 70s was referred to our hospital for further examination of a liver tumor(S3, 3 cm)detected by ultrasonography. Multimodal image examination showed a cystic lesion with solid papillary components located in the S4 accompanied by dilatation of the surrounding intrahepatic bile duct. Although biliary cytology did not indicate confirmed malignancy, the lesion was thought to be an intraductal papillary neoplasm of bile duct(IPNB)with malignant potential, and a left lobectomy was performed. Histopathological examination revealed a papillary tumor in the intrahepatic bile duct which consisted of atypical epithelial cells of pancreatobiliary type, and the lesion was diagnosed as an IPNB with high-grade intraepithelial neoplasia. Case 2 A woman in her 70s was referred to our hospital because of a liver tumor(S4, 8 cm)detected by ultrasonography. Multimodal image examination showed a cystic lesion localized to the liver(S3, 8 cm), and endoscopic retrograde cholangiopancreatography(ERCP)showed continuity of the cyst and the intrahepatic bile duct. The biliary cytology was positive, and the lesion was thought to be a malignant IPNB. After preoperative drainage of the cystic lesion, a left lobectomy was conducted. Histopathological examination showed that the papillary tumor localized to t
