Objective To report three cases of localized primary sclerosing cholangitis (PSC) mimicking a hilar cholangiocarcinoma (Klatskin tumor) and to summarize their clinical characteristics and the ways to differentiate them through a literature review.Method The clinical data of three patients with localized PSC mimicking a hilar cholangiocarcinoma were retrospectively analyzed.The characteristics of laboratory tests and imaging examination were reviewed,and therapy and prognosis were discussed.Results The three patients were all diagnosed to have a hilar cholangiocarcinoma preoperatively,but the diagnosis of PSC was confirmed by histopathology post-operatively.All the three patients had elevated CA19-9,2 patients had elevated anti-nuclear antibody (ANA) and 2 patients had elevated IgG.All the three patients underwent surgical resection and histopathological study showed chronic inflammation of the hilar bile ducts and cholangitis of the intrahepatic portal area.The three patients were followed up from 7 months to 8 years with no symptoms.Conclusions Localized PSC is rare and it can casily be misdiagnosed as a hilar cholangiocarcinoma.Biopsy before surgery is helpful for the differential diagnosis but it is difficult to get a good biopsy sample.Surgical resection is an effective treatment.

Objective To explore the relationship between the diabetic retinopathy (DR) and the carotid artery intima-media thickness(IMT) in type 2 diabetic patients to reveal the relationship between macroangiopathy and microangiopathy in diabetic patients further. Methods One hundred and tweenty-three diabetic cases in patient chosen from 2008 to 2009 were divided into diabetic retinopathy group(DR) and non-diabetic retinopathy group(NDR) by fundus examination. The patients were asked about their disease history including durations, smoking and so on. Meanwhile the carotid artery IMT, systolic pressure (SBP), diastolic pressure (DBP), serum total cholesterol, triglycerides, high density lipoprotein (HDL)-cholesterol, low density lipoprotein (LDL)-cholesterol, glycosylated hemoglobin(HbAlc), body mass index(BMI) were measured of all the cases. The incidence of increased carotid artery IMT was cmpared with χ2 test, as well as the average IMT between the two groups, the influencing factors artery IMT was 50.98%(26/51) in DR group, and 33.33%(24/72) in NDR group, having a statistically significant showed the diabetic retinopathy risk factors were smoking(χ2=6.20, P<0.05), duration(t=-4.13, P<0.01). carotid artery IMT(t=-2.21, P<0.05), SBP(t=-2.37, P<0.05), and HDL-cholesterol(t=4.49, all P<0.01). 12.77, all P<0.01), carotid artery 1MT and smoking(χ2=6.05,4.15, all P<0.05). Conclusions Type 2 diabetic patients complicated with DR have a prominent increase in IMT thickening proportion and average IMT, which reveals the relationship between the DR and the IMT.
