The early damage detection and evaluation are of great significance in treatment and prognosis to the left ventricular function for children with tumor. In this paper, it is reported that the early damage of the left ventricular function was observed by pulsed wave Doppler (PWD) and tissue Doppler imaging (TDI) in our laboratory. Eighty children half a year to fourteen years old were included in this study. The cardiac function indices in chemotherapy group and control group were measured and compared. The results showed that there was significant difference in mitral and tricuspid annulus flow spectrum between the two groups. Compared with PWD, TDI is more prompt, objective and accurate in detecting early damage of left ventricular function in children with tumor.And TDI is a good method for early identification of ventricular function damage in children with tumor.
ObjectiveTo compare the complication morbidity of mechanical and hand-sewn esophagogastric anastomosis systemically. MethodsMedline (January 1960 to June 2015), EMbase (January 1980 to June 2015), Cochrane Library (January 1996 to June 2015), Web of Science (January 1980 to June 2015) and other databases were searched to identify randomized controlled trials (RCTs) about comparing the complication morbidity of hand-sewn and mechanical anastomosis. Moreover, the references were searched by search engines such as Google Scholar. Papers were screened according to the inclusion and exclusion criteria. And then the data were extracted. The quality of current meta-analysis was assessed by GRADE profiler 3.6 software. The meta-analysis was conducted using Stata 12.0 software. ResultsA total of 1 611 patients in 14 RCTs were reviewed. The results suggested that the anastomatic leakage rate of mechanical method showed no significant difference from that of hand-sewn method[RR=1.07, 95%CI (0.76, 1.51), P=0.699]. While the anastomatic stenosis rate was even higher[RR=1.59, 95%CI (1.21, 2.09), P=0.001]. ConclusionMechanical method can't reduce the anastomotic leakage rate following esophagogastrostomy, while it maybe increase the risk of anastomotic stenosis on the contrary. The patients' physical condition should be considered when surgeons make the choice.
ObjectiveTo find the relationship between bicuspid aortic valve (BAV) and the dilatation or aneurysm of the aorta using electrocardiogram-gated computed tomography angiography (CTA). MethodsWe collected the clinical data of the BAV coexisting with suspected aortic dilatation or aneurysm from February 2012 through April 2015. A total of 124 patients were analyzed retrospectively. There were 97 males and 27 females at an anverage age of 50.35±16.26 years. According to the CTA, patients were classified into two groups: a pure BAV(without raphe) group and a BAV (with raphe) group. we recorded the aortic diameters, gender, age, and so on. ResultsOf the 124 patients, 91 (73.4%) had BAV with raphe, and 33 patients (26.6%) had pure BAV. The analysis revealed that the diameter of the annulus (23.90±3.34 mm vs. 21.74±3.46 mm, P=0.005), the sinuses of Valsalva (40.93±6.78 mm vs. 37.35±7.06 mm, P=0.022), the tubular portion of the ascending aorta (45.38±7.66 mm vs. 38.29±8.18 mm, P=0.0001), and the part of the aorta proximal to the innominate artery (34.19±4.98 mm vs. 30.23±6.62 mm, P=0.02) between patients with BAV with raphe and pure BAV had significant differences. And there was a significant difference in prevalence of dilatation of the aorta between patients with pure BAV and BAV with raphe [77/91 (84.6%) vs.18/31(58.1%), P=0.004]. Of the 91 BAV with raphe patients, we found 76 patients (83.5%) with right and left coronary cusps (R-L) fusion, 13 patients (14.3%) with right and non-coronary cusps (R-N) fusion, and 2 patients (1.2%) with left and non-coronary cusps (L-N) fusion. There was a statistical difference in the aortic root diameters between R-L fusion BAV and R-N fusion BAV. The diameter of the distal ascending aorta and proximal aortic arch between R-L and R-N fusion BAV had statistical differences. ConclusionsBAV with raphe is more common than pure BAV and is more often associated with dilatation and aneurysm of the ascending aorta. Otherwise R-L fusion BAV is associated with increased diameters of the aortic root, while R-N fusion BAV is associated with increased diameters of the distal ascending aorta and proximal arch.
ObjectiveTo investigate the application of imbedding pancreaticojejunostomy in pure laparoscopic pancreaticoduodenectomy. MethodsEighty-five cases of laparoscopic pancreaticoduodenectomy in our hospital from May 2014 to December 2015 were analyzed retrospectively. According with inclusion criteria and exclusion criteria, 78 cases were investigated. They were divided into pancreatic duct-to-jejunum mucosa pancreaticojejunostomy group as controlled group (n=42) and imbedding pancreaticojejunostomy (technique of duct-to-mucosa PJ with transpancreatic interlocking mattress sutures) group as modified group (n=36). The rates of pancreatic fistula, abdominal infection/abscess, bile leakage, delayed gastric emptying, gastrointestinal/intraabdominal hemorrhage, pulmonary infection, and incision infection were investigated as well as hospital stays and pancreaticojejunostomy time in two groups were compared. ResultsThe rate of pancreatic fistula especially B to C grade pancreatic fistula in the modified group was obviously lower compared with which in the controlled group (8.3% vs. 31.0%, P < 0.05), pancreaticojejunostomy time ofmodified group was significantly shortened [(35.6±12.4) min vs. (52.8±24.6) min, P < 0.05] and total operative time also shortened [(322.4±23.6) min vs. (384.2±30.2) min, P < 0.05). There were no significant difference of the rates of abdominal infection/abscess, bile leakage, delayed gastric emptying, gastrointestinal/intraabdominal hemorrhage, pulmonary infection, ?incision infection, and hospital stays (P > 0.05)]. Conciusions The type of pancreaticojejunostomy has a significant impact on the rate of pancreatic fistula after laparoscopic pancreaticoduodenectomy. Imbedding pancreaticojejunostomy can decrease the rate of pancreatic fistula after operation, and shorten the pancreaticojejunostomy time and total operative time.
