Hilar cholangiocarcinoma is defined as a malignant neoplasm involving right and left main hepatic ducts and/or its confluency. The disease is more prevalent in East Asia including Korea than Western countries and it may be due to the facts that hepatolithiasis, clonorchiasis and congenital anomaly of bile ducts are more frequent in this region. In this review, we will discuss about radiologic, endoscopic, and TNM staging along with preoperative assessment for surgical strategy in patients with hilar cholangiocarcinoma.

Intrahepatic cholangiocarcinoma (ICC) is the second most common primary malignant tumor in the liver after hepatocellular carcinoma. Its incidence and mortality rates have increased worldwide in recent years. Surgical resection is the best treatment modality for ICC;however,the overall prognosis remains poor. Accurate evaluation of post operative prognosis allows personalized treatment and improved long-term outcomes of ICC. The American Joint Commission on Cancer TNM staging manual is the basis for the standardized diagnosis and treatment of ICC;however,the contents of stage T and stage N need to be improved. The nomogram model or scoring system established in the analysis of commonly used clinicopathological parameters can provide individualized prognostic evaluation and improve prediction accuracy;however,more studies are needed to validate the results before clinical use. Meanwhile,imaging features exhibit great potential to establish the post operative prognosis evaluation system for ICC. Molecular-based classification provides an accurate guarantee for prognostic assessment as well as selection of populations that are sensitive to targeted therapy or immunotherapy. Therefore,the establishment of a prognosis evaluation system,based on clinical and pathological characteristics and centered on the combination of multidisciplinary and multi-omics,will be conducive to improving the long-term outcomes of ICC after surgical resection in the context of big medical data.

Objective: To examine the significance and prognostic value of the classification of hilar cholangiocarcinoma based on actual anatomical location. Methods: A retrospective study was conducted including 120 patients of hilar cholangiocarcinoma treated at the Second Affiliated Hospital,Zhejiang University School of Medicine and Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2019 to December 2021. Patients with hilar cholangiocarcinoma were classified for seven types according to the site of tumor location. The clinicopathological and prognostic data of 120 patients were retrospectively analyzed(There were 57 males and 63 females,the age (M(IQR)) was 61(22)years(range:42 to 85 years)). All patients received radical resection without visible intraoperative tumor residue and negative bile duct resection margin according to intraoperative pathological biopsy. The classification variables were analyzed by Pearson χ² test or Fisher's exact probability test,one-way ANOVA or Kruskal-Wallis rank sum test.Kaplan-Meier method was used for survival analysis. Cox proportional risk model was used for prognostic factors. Results: The coincidence rate of preoperative surgical planning and actual operational styles was verified in 33 cases. Twenty-six cases were consistent,and 7 cases were inconsistent,with a coincidence rate of 78.8%. According to the actual anatomical location,patients in type of secondary branch experienced a significantly longer operation duration,a higher portal vein resection rate,margin positive rate and more advanced T stage(all P<0.05). The median overall survival time of the unilateral main trunck group was 27.0 months,and the bilateral group was 17.0 months. Survival analysis based on the tumor classification of the actual anatomical location showed that the unilateral or main trunck group predicted less aggressive clinical features and favorable outcomes(HR=1.931,95%CI:1.066 to 3.499,P<0.05). Multivariate analysis demonstrated that the actual anatomical location of the tumor type(HR=2.269,95%CI:1.333 to 3.861,P=0.003),combined liver resection(HR=0.464,95%CI:0.253 to 0.848,P=0.013) and N stage(HR=6.317,95%CI:3.083 to 12.944,P<0.01) were independent factors affecting the prognosis of patients. Conclusion: The classification based on the actual anatomy can be used as a promising scheme in refining patient stratification and predicting survival in hilar cholangiocarcinoma,and it can guide the selection of surgical methods,and predict operative safety and radical resection rate.

Leiomyomas, originating in the bile duct, are very rare, and only few cases have been reported in the literature. We experienced a case of leiomyoma of the distal common bile duct, mimicking bile duct cancer. A 39-year-old woman presented with intermittent jaundice and general weakness for three months. Clinical profiles showed obstructive jaundice, and the abdominal computed tomography and cholangiography revealed diffuse bile duct dilatation with distal common bile duct stricture. A pylorus-preserving pancreaticoduodenectomy was performed and the pathologic specimen disclosed leiomyoma of the common bile duct accompanying severe fibrosis. This is the first case of leiomyoma in the bile duct reported in Korea.
