OBJECTIVETo summarize the clinical experiences in treating primary tracheal tumors by surgery.

METHODSThe clinical data concerning 70 surgically treated patients between 1968 and 2001 were retrospectively analyzed.

RESULTSThere were 39 sleeve tracheal resections, 13 carinal resections, 10 lateral tracheal wall resections, 5 local enucleations, and 1 pneumonectomy. The tumors in 2 patients were unresectable. The morbidity rate was 31% (22/70) and operative 30-day mortality for resection with primary reconstruction was 8% (4/52). The tumors were benign in 14 and malignant in 56 cases. The most common malignant tumors were adenoidcystic carcinoma (45%) and squamous cell carcinoma (23%). The cases of benign tracheal tumors were followed up for an average of 5.7 years. After resection for malignant tumors, the overall 5- and 10-year survival rates were 64% (21/33) and 54% (14/26), respectively.

CONCLUSIONSSurgical resection is the most effective treatment of tracheal tumors. Tracheal resection and reconstruction is the treatment of choice for primary tracheal tumors. Benign tumors should be resected conservatively with preservation of tracheal parenchyma. The reduction of operative complications are key points of good surgical results.

OBJECTIVETo analyze the perioperative clinical data of children with congenital heart disease complicated by acute kidney injury (AKI) after cardiopulmonary bypass (CPB) surgery, and to explore potential factors influencing the prognosis.

METHODSA retrospective analysis was performed among 118 children with congenital heart disease who developed AKI within 48 hours after CPB surgery.

RESULTSIn the 118 patients, 18 died after 48 hours of surgery. Compared with the survivors, the dead children had significantly higher incidence of cyanotic disease and Risk Adjustment for Congenital Heart Surgery-1 (RACHS-1) scores before surgery; during surgery, the dead children had significantly longer CPB time and aortic cross-clamping time, a significantly higher proportion of patients receiving crystalloid solution for myocardial protection, and a significantly higher mean blood glucose level. Within 48 hours after surgery, the dead children had significantly higher positive inotropic drug scores, significantly higher creatinine values, a significantly higher incidence of stage 3 AKI, a significantly higher proportion of patients receiving renal replacement the, and significantly higher usage of blood products (P<0.05). The mortality rate of the patients increased with increased intraoperative blood glucose levels (P<0.05). Patients with intraoperative blood glucose levels >8.3 mmol/L had a significantly lower postoperative cumulative survival rate and a significantly shorter mean survival time than those with blood glucose levels ≤ 8.3 mmol/L (P<0.05).

CONCLUSIONSIntraoperative blood glucose levels are associated with the prognosis in children with congenital heart disease complicated by AKI after CPB surgery. Maintaining good intraoperative blood glucose control can improve the prognosis of the children.

BACKGROUNDAlthough liver transplantation has become a standard therapy for end-stage liver diseases, the experience of pediatric liver transplantation is limited in China. In this article we report our experience in pediatric liver transplantation, and summarize its characters in their indications, surgical techniques, and postoperative managements.

METHODSThirty-one children (< or = 18 years old) underwent liver transplantation in our centers. The mean age at transplantation was 12.4 years old (ranged from 5 months to 18 years) with 7 children being less than 4 years of age at transplantation. The most common diagnosis of patients who underwent liver transplantation were biliary atresia, Wilson's disease, primary biliary cirrhosis, glycogen storage disease, hepatoblastoma, urea cycle defects, fulminant hepatic failure, etc. The surgical procedures included 12 standard (without venovenous bypass), 6 pigyback, 6 reduced-size, 3 split, 3 living donor liver transplantation, and 1 Domino liver transplantation. The triple-drug (FK506, steroid, and mycophenolate mofetil) immunosuppressive regimen was used in most of patients. Patients were followed up for a mean of 21.8 months.

RESULTSFive of the 31 patients died during perioperative time; mortality rate was 16.1%. The reasons of death were infections, primary non-function, heart failure, and hypovolemic shock. Postoperative complications in 10 patients included biliary leakage, acute rejection, abdominal infection, hepatitis B virus (HBV) or hepatitis C virus (HCV) infection, and pulmonary infection. Overall patient cumulative survival rate at 1-, 3-, and 5-year was 78.1%, 62.6%, 62.6%, respectively.

CONCLUSIONSThe most common indications of pediatric liver transplantation were congenital end-stage liver diseases. According to patients' age and body weight, standard, piggyback, reduced-size, split, or living donor liver transplantation should be performed. Pediatric liver transplantation especially requires higher surgical skills. The early postoperative management is the key to success. Postoperative bile leak was common, but most patients underwent liver transplantation had a better prognosis.

OBJECTIVETo compare the clinical outcomes of open surgical peritoneal dialysis catheter (PDC) insertion with guide wire and the outcomes of PDC insertion without guide wire.

METHODSData of the patients receiving open surgical Tenkchoff straight catheter insertion in our department from January 2005 to January 2011 were retrospectively analyzed. The 117 patients in whom PDC insertion was conducted with the guidance of guide wire were enrolled into group A, and the 121 cases receiving PDC insertion without guide wire were enrolled into group B. The incidences of post-operative complications (catheter obstruction, catheter displacement, bloody dialysate, and dialysate leakage), catheter survival, and patient survival rates were compared between the 2 groups.

RESULTSThe baseline characteristics (gender, age, body mass index, prothrombin time, activated partial thromboplastin time, platelet count, serum creatinine, follow-up time, primary diseases, and outcomes) of the 2 groups were comparable (all P>0.05). In post-operative complications, only the incidence of early bloody dialysate showed significant difference, being 16.2% in group A and 7.4% in group B (P=0.04). Catheter and patient survival rates were not significantly different between the two groups. Overweight patients showed a higher incidence of catheter obstruction compared with normal weight patients [16.0% (4/25) vs.3.3% (7/213), P=0.02], but no differences in post-operative complications were found among overweight patients between the 2 groups.

CONCLUSIONSOpen surgical Tenkchoff straight catheter insertion without guide wire does not lead to higher risk of post-operative complications and catheter removal. It may be an alternative option when guide wire is not available.

The aim of this study was to evaluate the infectious complications after living donor liver transplantation (LDLT) in children. We enrolled 95 children (38 boys and 57 girls) who underwent LDLT from 1994 to 2004. The median age was 22 months (range, 6 months to 15 yr). We retrospectively investigated the proven episodes of bacterial, viral, and fungal infection. There occurred 150 infections in 67 (70%) of 95 patients (1.49 infections/patient); 74 in 43 patients were bacterial, 2 in 2 were fungal, and 74 in 42 were viral. The most common sites of bacterial infection were the bloodstream (33%) and abdomen (25%). Most of the bacterial infections occurred within the first month after LDLT. Bacterial and fungal infections did not result in any deaths. The most common causes of viral infection were Epstein-Barr virus in 37 patients and cytomegalovirus in 18. Seven of the 14 deaths after LDLT were associated with viral infection. Our study suggests that infection is one of the important causes of morbidity and mortality after LDLT. Especially careful monitoring and management of viral infections is crucial for improving the outcome of LDLT in children.

OBJECTIVE: To evaluate the impact of Down syndrome (DS) on surgical management in patients with congenital heart defects (CHD). METHODS: We retrospectively analyzed the clinical data from 35 children with DS and CHD, who underwent cardiac surgery between 2004 and 2009. The data on surgical mortality, complications and follow-up results are emphasized. RESULTS: All of the patients underwent primary repair. One child (2.9%) with DS and complete atrioventricular septal defect (CAVSD) died early postoperatively because of pulmonary hypertension. Two patients (5.7%) had low cardiac output syndrome, and 15 (42.9%) suffered pulmonary complications. III degree atrioventricular block (AVB) occurred in 4 patients (11.5%). Thirty children who were followed up 10 months to 6 years [(3.8±1.1) years] are in NYHA class I or II. There were no reoperations or later death. CONCLUSION CHD in DS children can be repaired with a low risk of mortality, although a high incidence of severe infections and III degree AVB can result in a complicated postoperative course. The results of mid-term follow up are satisfactory.

BACKGROUNDAlthough most patients with tetralogy of Fallot undergo radical repair during infancy and childhood, patients that remain undiagnosed and untreated until adulthood can still be treated. This study aimed to evaluate longterm outcomes of adult patients with tetralogy of Fallot who were treated surgically, and to determine the predictors of postoperative pulmonary regurgitation.

METHODSFifty-six adult patients underwent complete surgical repair. Forty-three patients (76.8%) required a transannular patch. Systolic, diastolic, and mean pressure in the main pulmonary artery were measured after repair.

RESULTSThe early mortality rate was 3.6%. The 16-year survival rate was (84.4 ± 11.5)%. Late echocardiography revealed 41 patients with transannular patch who had pulmonary regurgitation, consisting of mild pulmonary regurgitation in 28 patients, moderate in eight, and severe regurgitation in five patients. In addition, there was right ventricular outflow tract stenosis in nine patients, moderate/severe tricuspid valve regurgitation in seven, and residual ventricular septal defect in five. Logistic regression analysis demonstrated that the mean pulmonary pressure measured just after repair predicted late pulmonary regurgitation.

CONCLUSIONSThe long-term survival of surgically treated adult patients with tetralogy of Fallot is acceptable. The mean pressure >20 mmHg in the main pulmonary artery measured right after surgical repair may be a feasible reference to time the reconstruction of the pulmonary valve.

BACKGROUNDGastrojejunostomy (GJJ) and endoscopic stenting (ES) are palliative treatments for gastric outlet obstruction (GOO) caused by gastric cancer. We compared the outcomes of GJJ with ES by performing a meta-analysis.

METHODSClinical trials that compared GJJ with ES for the treatment of GOO in gastric cancer were included in the meta-analysis. Procedure time, time to resumption of oral intake, duration of hospital stay, patency duration, and overall survival days were compared using weighted mean differences (WMDs). Technical success, clinical success, procedure-related mortality, complications, the rate of re-obstruction, postoperative chemotherapy, and reintervention were compared using odds ratios (OR s).

RESULTSNine studies were included in the analysis. Technical success and clinical success were not significantly different between the ES and GJJ groups. The ES group had a shorter procedure time (WMD = -80.89 min, 95% confidence interval [CI] = -93.99 to -67.78,P < 0.001), faster resumption of oral intake (WMD = -3.45 days, 95% CI = -5.25 to -1.65,P < 0.001), and shorter duration of hospital stay (WMD = -7.67 days, 95% CI = -11.02 to -4.33,P < 0.001). The rate of minor complications was significantly higher in the GJJ group (OR = 0.13, 95% CI = 0.04-0.40,P < 0.001). However, the rates of major complications (OR = 6.91, 95% CI = 3.90-12.25,P < 0.001), re-obstruction (OR= 7.75, 95% CI = 4.06-14.78,P < 0.001), and reintervention (OR= 6.27, 95% CI = 3.36-11.68,P < 0.001) were significantly lower in the GJJ group than that in the ES group. Moreover, GJJ was significantly associated with a longer patency duration (WMD = -167.16 days, 95% CI = -254.01 to -89.31,P < 0.001) and overall survival (WMD = -103.20 days, 95% CI = -161.49 to -44.91, P= 0.001).

CONCLUSIONSBoth GJJ and ES are effective procedures for the treatment of GOO caused by gastric cancer. ES is associated with better short-term outcomes. GJJ is preferable to ES in terms of its lower rate of stent-related complications, re-obstruction, and reintervention. GJJ should be considered a treatment option for patients with a long life expectancy and good performance status.
