ABSTRACT

Objective Hilar cholangiocarcinoma (HC) is invariably fatal without surgical resection. The primary aim of the current study was to determine the safety of variable surgical resections for patient with HC and their survival after surgical resection. In addition, prognostic factor for the overall survival was also evaluated. Methods The study included 59 consecutive patients who were newly diagnosed with HC and underwent surgical resections with curative intend between February 2009 and February 2017. Patients were followed up at 3-6 months intervals after hospital discharge. Postoperative complications and overall survival were determined. Associations of clinicopathologic and surgeon-related factors with overall survival were evaluated through univariate analysis and Cox regression analysis. Results Of patients with Bismuth and Corlette (B & C) type Ⅲ (=19) and Ⅳ (=25) HC lesions, 33 (55.9%) were treated with hilar resection combined with major liver resection (MLR), while the other 11 patients with type Ⅲ and Ⅳ, and those with type Ⅰ (=8) and Ⅱ (=7) HC lesions were treated with hilar resection. The overall surgical mortality was 5.1% and surgical morbidity was 35.6%. There was no statistical difference in the mortality between MLR group and hilar resection group (6.1% 3.8%; =0.703, =0.145). The median follow-up period was 18 months (range, 1-94 months). The 1-, 3-, 5-year survival rate was 59.3%, 36.5%, and 17.7%, respectively. The overall survival after resections was 18 months. In HC patients with B & C type Ⅲ and Ⅳ lesions, the median survival was 23 months for hilar resection with MLR and 8 months for hilar resection alone; the 1-, 3-, 5-year cumulative survival rate was 63.9%, 23.3%, and 15.5%, respectively for hilar resection with MLR, and 11.1%, 0, and 0, respectively for hilar resection alone, with significant differene observed (, 9.902; 95% , 2.636-19.571, =0.001). Four factors were independently associated with overall survival: preoperative serum Ca19-9 (, 7.039; 95% , 2.803-17.678, <0.001), histopathologic grade (, 4.964; 95% , 1.046-23.552, =0.044), surgical margins (=0.031), and AJCC staging (=0.015). Conclusions R0 resection is efficacious in surgical treatment of HC. MLR in combination with caudate lobe resection may increase the chance of R0 resection and improve survival of HC patients with B & C type Ⅲ and Ⅳ lesions. Preoperatively prepared for biliary drainage may ensure the safety of MLR in most HC patients. Novel adjuvant therapies are needed to improve the survival of HC patients with poor prognostic factors.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the methods of interventional catheterization for combined congenital heart disease and to evaluate its efficacy in children.</p><p><b>METHODS</b>From March 1994 to December 2003, 15 cases (6 boys, 9 girls) underwent transcatheter intervention for combined congenital heart diseases. The procedure of transcatheter intervention was as follows: for pulmonary stenosis (PS) and atrial septal defect (ASD) or patent ductus arteriosus (PDA), PBPV first, occlusion of ASD or PDA later; for coarctation of aorta (COA) and PDA, dilation of COA first, occlusion of PDA 4-15 months later; for aortic stenosis (AS) and PDA, PBAV first, occlusion of PDA later; for ventricular septal defect (VSD) and PDA, all occlusions with detachable coils.</p><p><b>RESULT</b>Transcatheter intervention for combined congenital heart diseases was successful in all patients. There was no residual shunt after occlusion immediately apart from 2 cases of PDA which were little residual after occlusion immediately. Follow-up for (3.57 +/-2.61) years, the systolic pressure gradients across pulmonary valve and coarctation were normal by ultrasonic or transcatheter, except AS. There was 3 cases presented postoperative complications: 1 with mechanical haemolysis, 1 with fall off of coil and 1 with arterial embolism, respectively.</p><p><b>CONCLUSION</b>Transcatheter intervention for combined congenital heart diseases could obtain satisfactory results with appropriate indications and procedure manipulations.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To understand whether hyperhomocysteinemia and early arterial atherosclerosis exist in simply obese children.</p><p><b>METHODS</b>Totally 68 simply obese children (age 6-14 years, mean 10.8 +/- 2.3 years) were enrolled in this study, 50 were male and 18 were female. Body mass index (BMI) of the obese children was equal to or more than 22. The height of the children was (145 +/- 22) cm. Meanwhile, 26 normal children (age 6 - 14 years, mean 10.9 +/- 2.0 years) were selected as control group, 17 of these children were male and 9 were female. Their height was (148.5 +/- 5.8) cm. There were no significant differences in height and age between the obese and the control children. The carotid intimal-medial thickness (IMT), brachial artery flow-mediated vasodilation were examined by Doppler Flow/Dimension System and the liver was examined by B-mode ultrasound imager. Plasma homocysteine was determined by the automated chemiluminescent enzyme immunoassays. Serum lipid concentration was determined by biochemical analytic method. Blood pressure of the right upper limbs was measured. A detailed medical and family history was systematically recorded.</p><p><b>RESULTS</b>BMI was (27.8 +/- 4.5) in the obese children and (16.2 +/- 2.5) in the controls. There was significant difference between two groups (P < 0.01). The obese children had significantly increased values than the controls for the carotid intimal-medial thickness (P < 0.01). Right carotid IMT, right inner-carotid IMT, left carotid IMT and left inner-carotid IMT were respectively (0.54 +/- 0.13) mm, (0.69 +/- 0.14) mm, (0.52 +/- 0.12) mm and (0.67 +/- 0.14) mm in obese children and were respectively (0.45 +/- 0.04) mm, (0.46 +/- 0.04) mm, (0.45 +/- 0.05) mm and (0.46 +/- 0.03) mm in control groups. Conversely, the flow-mediated brachial artery dilation of the obese children was significantly lower than that of the controls [(11.0 +/- 4.3)% vs. (17.5 +/- 4.9)%, P < 0.01]. The obese children had higher level of plasma homocysteine than the controls [(7.9 +/- 2.7) micromol/L vs. (5.6 +/- 2.1) micromol/L, P < 0.01]. Total cholesterol (TC) in the obese children dramatically increased, so did triglyceride concentration (TG), LDL-cholesterol (LDL-ch) and apolipoprotein-B (apo-B). Of the obese children, had fatty liver or the tendency to fatty liver. Six cases of the 68 obese children (8%) had hypertension. Of the 68 obese children, 57 (84%) had the history of consuming excessive food or taking less exercise. Forty-four percent of the obese children (30/68) came from the obese families in which at least one of the parents or grandparents was obese. Twenty-nine percent (20/68) and 22% (15/68) of the obese children respectively came from the families in which at least one of the parents or grandparents suffered from hypertension or coronary heart disease.</p><p><b>CONCLUSION</b>Early arterial atherosclerotic changes existed in simply obese children. Hyperhomocysteinemia may be an important factor of the obesity-induced early arterial atherosclerosis during childhood.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the relationship between the age at operation and prognosis in children with severe pulmonary hypertension (PH) due to ventricular septal defect (VSD).</p><p><b>METHODS</b>Forty children with severe PH (increased total pulmonary circulation resistance)due to VSD were divided into two groups based on age at operation(Group I aged less than 2 years and group II more than 2 years). The hemodynamic parameter follow-up was measured by cardiac catheterization at presurgery, one week after surgery and 5-7 years postoperatively.</p><p><b>RESULTS</b>The ratio of pulmonary arterial pressure and systemic arterial pressure (pp/ps),pulmonary resistance and systemic resistance (R(p)/R(s)), and pulmonary vascular resistance (PVR) and small pulmonary arterial resistance (PAR) were significantly different in two groups (P<0.01). During follow-up in the group less than 2 years, all the hemodynamic parameters were at normal level, while in the group more than 2 years, only p(p)/p(s) and R(p)/R(s) were close to normal level. The pulmonary arterial resistance was still abnormal.</p><p><b>CONCLUSION</b>An early operation may be the only way to gain optimal long term result of surgery and decrease the incidence of pulmonary vascular disease in children with PH due to VSD.</p>

ABSTRACT

Objective In order to explore practical values of the revised Duck criteria for diagnosis and treatment of pediatric infective endocarditis(IE).Methods Seventy-three children′s cases diagnosed and treatmented as IE complicated with congenital heart defects in the past 22 years were collected to make retrospective analysis according to the Duck criteria.Results In 73 patients,a definite diagnosis of IE was made in 37 patients(51%),16(43%) of which proved by the pathologic lesions during the operations.Eight patients(22%) met two major criteria,13 patients(35%) met one major and more than 3 minor criteria.36 patients(49%) were diagnosed as possible IE.Forty-five patients(62%) were cured using antibiotic therapy.Sixteen cases(21%) were failure in antibiotic treatment,of whom 16 patients were operated by cutting off the detection of vegetation and repairing the heart malformation.Tweleve cases(17%) were died,one of which was died after the operation.Conclusions IE is still a significant complication of congenital heart disease.Duck criteria is relative rigid in sensitivity,but it is high in specificity.When the vegetation isn′t large enough in shape,revised Duck criteria is difficult to(diagnose) early.The surgery treatment is optimistic.To combine the medicine with surgery can contributed to decrease mortality rate.
