Objective To study the diagnosis and radical resection of hilar cholangiocarcinoma. Methods Retrospective analysis was made on the clinical feature and the effect of radical resection on 38 cases of hilar cholangiocarcinomas.Results Diagnosis was made in all of the patients preoperatively.The radical resection was perfomed on 38 patients.Of them, 3(7.9%) died after operation.After operation, 5 cases (13.2%) developed bile leakage,and 2 of the 5 cases developed subphrenic abscess,which were cured by drainage; 4(10.5%) had right hydrothorax that was cured by conservative therapy; and 3(7.9%)had incision split that was cured by resuture. Among the 35 postoperative survivors,34 (97.1%) were followed up, the 1- and 3-year survival rates were 91.9% and 35.2%.None of the patients survived for 5 years. Conclusions It′s still difficult to make early diagnosis in hilar cholangiocarcinoma.The diagnosis mainly depends on the combination of imaging examinations. Nowadays the radical resection rate of hilar cholangiocarunoma is still low, the recurrence and metastasis are common after operation, and few patients can survive for a long time. It suggests that even in radical operation for hilar cholangiocarcinoma, the regions of resection and sweep are not enough,and the operative procedure needs to improve further.

Objective To explore the MR imaging of reverse and separation of meniscal articular capsule.Methods MR imaging of reverse and separation of meniscus articular capsule confirmed by surgery and arthroscope were analyzed retrospectively in 8 cases.Results The “Butterfly knot sign” disappeared and was replaced with fluid signal on the sagittal slice of meniscal body in 8 cases. Part of back angle remained in 3 cases. “Double anterior cruciate ligament sign” was showed on one side of middle sagittal slice in 7 cases. “Reverse meniscus sign” was revealed in intercondylar fossa on the coronary view in ~8 cases. Abnormal high signal was showed in the injured meniscus in 6 cases. Abnormal high signal was detected in the opposite meniscus in 5 cases.Conclusion The MR findings of reverse and separation of meniscus articular capsule include disappearance of “butterfly knot sign”, appearance of “reverse meniscus sign” and “double anterior cruciate ligament sign”. The diagnosis would be established if the former 2 signs were present or all the 3 signs were present simultaneously.

Time to positivity(TTP) is a new parameter in blood culture field.The article shows us the concepts of TTP,differential time to positivity (DTTP),and introduces their relation with bloodstream infection (BSI),catheter-related bloodstream infection (CRBSI).Besides,it stresses TTP' s clinical application,including determining the severity of disease;identifying the isolates whether pollution or not; identification of isolate strains ; detection of the drug resistance of isolates ; evaluating the effect of antibiotic ; helping to adjust the therapeutic drug; diagnosing or excluding CRBSI by means of DTTP;deciding whether the catheter is the source of infection in patients with candidemia; understanding the epidemiological distribution of strain.At the same time,the article also describes the shortcomings and domestic current status.

Objective To investigate the approaches for diagnosis and treatment of intrahepatic cholangiocarcinoma(ICC)and asgess its prognosis factors.Methods The clinical data of 86 patients with ICC in our hospital from January 1995 to December2005 were retrospeetively analyzed.All patients were divided into two groups according to the treatment method,including hepatectomy and lymphatic clearance group(Group A,n=42)and hepateetomy group(Group B,n=44),and their clinicopathological variables were analyzed.Resuits The 1-,3-and 5-year survival rates were 77.81%and 35.21%,20.93%and 19.82%,2.31%and 0%respectively between group A and group B.There was significantly difference between these two groups(P＜0.01).The analysis showed that resection and lymphatic clearance were correlated to prognosis.The 1-,3-and 5-year survival rates were 59.21%,26.21%,and 20.11% respectively in 47 patients who were found no lymph node metastasis,and the 1-,3-and 5-year survival rates were 19.82%,2.31%and 0% respectively in 39 patients who were found lymph node metastasis.There was significantly difference in survival rate between group A and group B(P＜0.01).Condusions Reseetability and lymphatic clearance are two significant factors correlated to survival of the patients with ICC.Aggresgive treatment of lymph node metastasis in hepatoduodenal ligament is an important strategy to improve survival rates and strengthen patient's life quality.

Objective To analyze the clinical characteristics of twin reversed arterial perfusion sequence (TRAP),and investigate its prenatal evaluation and clinical management.Methods Karyotype results and ultrasound data of 25 TRAP cases were retrospectively reviewed,including estimated weight and umbilical blood flow of acardiac twin,cardiac function and middle cerebral artery peak systolic velocity of pump twin.Various managements and the outcomes were analyzed.Results (1) Karyotype of amniotie fluid were tested in 16 pump twins.Mosaicism was found in 1 case (46,XX[36]/46,XY [14]).(2) According to the ultrasound evaluation,large acardia accounted for 87.0％ (20/23) cases.Abundant blood perfusion (inter-twin difference of umbilical resistance index ≤0.20) was indicated in 86.4％ (19/22) cases.Decompensation of cardiac function was suggested in 66.7％ (10/15) pump twins.Fetal anemia of pump twin indicated by middle cerebral artery peak systolic velocity＞1.5 multiples of the median was diagnosed in 75.0％ (12/16) cases.(3) The acardiac twin with abundant blood perfusion was more likely to be a large acardia than those without [94.7％(18/19) vs 1/3,Fisher exact test,P=0.04]; More pump twin with large acardia tended to have cardiac decompensation than non-large acardia pump twins [83.3 ％ (10/12) vs 0/3,Fisher exact test,P=0.02].(4) Eleven patients chose to terminate their pregnancies after being diagnosed.In 14 cases who continue the pregnancies,the survival rate of pump twin was 64.3％ (9/14).In 3 cases of non-large acardia without cardiac decompensation of pump twin,the patients selected conservative observation resulting in 2 term deliveries and 1 termination of pregnancy due to for exacerbation.Among 11 cases with large acardia,which the pump twins were complicated by cardiac decompensation or anemia,five cases selected conservative observation.One ended in spontaneous abortion; three exacerbated (one termination and two cesarean section before term with living births) ; one was stable until delivery.Another 6 cases received bipolar cord coagulation,and successful interruptions of acardiac blood flow were achieved in 5 cases among which 4 pump twins survived.Conclusions Prenatal diagnosis,cardiac function and fetal anemia of pump twin,together with the growth and blood supply of acardia are important indexes for prenatal evaluation of TRAP,on which our prompt management should be based.

Objective To analyze CT and MRI manifestations of the aneurysmal bone cyst and to evaluate the value of its imaging diagnosis.Methods The manifestations of CT and MRI of the aneurysmal bone cyst confirmed by operation or puncture were analysed retrospectively.Results On CT images,there were obvious liqued-liqued level within the lesions in 16 cases,in which,the CT values in up part was lower than that in low part,and there were obvious soft tissue mass in secondary aneurysmal bone cyst.While,on MRI,all lesions appeared obvious liqued-liqued level except one secondary example,and the soft tissue mass of secondary aneurysmal bone cyst was clear showed.Conclusion Most of aneurysmal bone cyst appear liqued-liqued level within the lesions on CT and MRI,it is a characteristic sign,but not the only one.

Objective To evaluate the diagnosis and application values of endoscopic ultrasonography (EUS) with micro-probe in duodenal lesions.Methods Clinical data of 37 patients with duodenal lesions and underwent EUS with micro-probe were analyzed retrospectively.All lesions were treated with endoscopic mucosal resection or surgical resection to get the pathological diagnosis.The diagnostic accuracy of EUS with microprobe and endoscopic biopsy was analyzed respectively.Results The overall diagnosis accuracy of EUS with micro-probe on duodenal lesions was 78.38％ (29/37),with a higher diagnostic rate in duodenal lipoma 4/4and duodenal adenomas 10/12 than in early duodenal cancer 2/4 or inflammatory hyperplasia 3/8.The overall diagnostic accuracy of biopsy on duodenal lesions was 40.54％ (15/37),with a higher diagnosis rate on duodenal carcinoid 1/1 and adenoma 7/12 than on duodenal stromal tumor 1/10 and lipoma 1/4.Conclusion Pathological evaluation of endoscopic biopsy sample is not a golden standard for the diagnosis of duodenal lesions,while EUS with micro-probe has better diagnostic and application value.

Objective To investigate the efficacy of sequential ERCP and laparoscopy for acute biliary pancreatitis (ABP).Methods A total of 80 patients with ABP were randomly divided into 2 groups to receive sequential ERCP and laparoscopy (observation group,n=40) or traditional surgery (control group,n=40).Clinical data including abdominal pain relief time,recovery time of white blood cell,blood amylase and liver function,hospital stay,complication rate and mortality were analyzed.Results ERCP failed in 1 patient in observation group,and the remaining 39 patients (97.5％) were recruited into the study.There were significant differences between 2 groups in regarding of abdominal pain relief time (7.7±2.7 d vs.11.4±3.7 d),recovery time of white blood cell ( 9.7±2.6 d vs.13.3±3.9 d ),blood amylase ( 8.2±2.1 d vs.12.5±3.3 d ),liver function ( 12.5±5.1 d vs.21.3±6.5 d ),hospital stay ( 16.1±5.1 d vs.23.3±7.6 d ) and rate of complication ( 12.8％ vs.30.0％ ).There was no significant difference in morbidity between 2 groups (5.1％ vs.7.5％).Conclusion Sequential ERCP and laparoscopy is effective for ABP.

Objective To report the clinical outcomes of applying endoscopic incision in the treatment of ureterovesical anastomosis site obstruction in transplanted kidneys. Methods Between February 2001 and April 2008, 13 men and 5 women with ureterovesical anastomotic site obstruction in their transplanted kidneys were treated by endoscopic incision with electrocautery or holmium: YAG laser. After the anastomosis was completely resected, two Double-J stents were placed in the ureter for 6-8 weeks. During follow-up, renal function, ultrasound examination and wash-out renal scintig-raphy were performed every month for the first 6 months, then every 3 months. Results Total 25 procedures of endoureterotomy were performed and all procedures resulted in successful incision of the obstruction. No complication was recorded during or after the procedure. At the mean follow-up of 51 months (range 4-90 months), 5 patients presented with recurred obstructive uropathy immediately after the Double-J stent removal and finally underwent open surgical correction. Conclusions Endo-scopic incision is safe and effective in the treatment of ureterovesical anastomosis site obstruction in transplanted kidney. However, open surgical reconstruction should be considered if endoscopic inci-sion procedure has failed.
