[Abstract]:Objective: To summarize the characteristics of echinococcosis cyst of hepatic cystic echinococcosis in children and evaluate the therapeutic effect of different surgical procedures in children with hepatic cystic echinococcosis. Through the correlation analysis of postoperative complications and clinical data of hepatic cystic echinococcosis in children, to find out the risk factors of complications and diagnosis in children's liver through imaging and serological diagnosis. The best method of diagnosis of single cystic echinococcosis in children was explored before the operation of cystic echinococcosis. The recombinant protein (rEgAgB1) of echinococcosis antigen B1 (rEgAgB1) was obtained by genetic engineering technology, and the value of its serological diagnosis for hepatic cystic echinococcosis in children was discussed, and the correlation analysis between the expression results and clinical data was carried out to find the influence of R. EgAgB1 in children with cystic echinococcosis serum related factors. Methods: 1 retrospective analysis and summary of the First Affiliated Hospital of Xinjiang Medical University from January 2002 to December 2014, 191 cases of children under 14 years of age (14 years old) with hepatic cystic echinococcosis, the sex, age, symptoms, cyst characteristics (position, size, quantity), operation of the patients, surgery The clinical data of the plan, the time of hospitalization and the postoperative complications were analyzed. The treatment scheme included the improved internal capsule extirpation group, the outer capsule subtotal excision and the complete exfoliation of the outer capsule. The patients' sex, signs, the bile leakage, the number of hepatic echinococcosis, the rupture of the hepatic echinococcosis, the size of the hydatid, the operation and the operation of the hydatid cyst, and the size of the hydatid cyst in the liver The correlation of postoperative complications was discussed. 2 a total of 100 cases of liver cystic echinococcosis and hepatic cysts confirmed by pathology of the First Affiliated Hospital of Xinjiang Medical University from January 2012 to 12 2014 were collected, including 50 cases of single cystic echinococcosis and 50 cases of simple hepatic cysts, including imaging ultrasound, CT examination and laboratory echinococcosis four items respectively. The sensitivity and specificity were calculated and combined with hydatid test, hydatid test, CT and echinococcosis test. 3 the rEgAgB1 prokaryotic expression plasmid (pET28a-EgAgB1) was transformed into E coli, high purity rEgAgB1 was purified by affinity chromatography, and 25 children with echinococcosis were purified by purified recombinant protein and HCF, respectively. The serum of normal children was detected by ELISA and Immunoblotting methods, and the clinical data of 25 children with hepatic cystic echinococcosis were analyzed. The age, family, symptoms and classification of the patients were analyzed. The relationship between the number of other organs, the number of hydatid, the size of echinococcosis and the rEgAgB1 in the serum. Results: 1) a total of 191 children were included in the study. There were 63 cases of benign internal capsule excision (group A), 89 cases (group B) and 39 cases of outer capsule complete dissection (group C). Through statistical analysis of the data of three groups, the time of operation and external capsule total excision group (group B) was significantly lower than that of the complete exfoliation of outer capsule (group C), but there was no significant difference with the modified internal capsule extirpation (group A); The amount of hemorrhage in the operation group (group B) was significantly lower than that of complete exfoliation (group C), but there was no significant difference from the improved internal capsule extirpation (group A). (group A) after operation, the time of improved internal capsule extirpation (group A) was significantly longer than that of the external capsule total excision group (group B) and the complete exfoliation of external capsule (group C); The number of days of hospitalization, improved internal capsule extirpation (group A) was significantly longer than that of the outer capsule subtotal excision group (group B) and the complete exfoliation of outer capsule (group C); (5) the postoperative residual cavity complications (residual cavity effusion, residual cavity infection, residual cavity bile leakage), the external capsule subtotal excision group (group B) was significantly lower than the modified internal capsule extirpation (group A), and the external capsule complete dissection (group C) There were no significant differences in 26 cases of postoperative complications. Single factor statistical analysis showed that postoperative complications and abdominal pain, hydatid cyst and biliary tract interlinked, pre operation hydatid cyst rupture, P0.05, and other indicators were not statistically significant. Single factor analysis did not control other factors interference, the P less than 0.1 variables Na In the multi factor regression model, two classification logistic regression was carried out. The results of abdominal pain, echinococcosis and biliary tract were interlinked, and the variable of echinococcosis was statistically significant, and the sensitivity of.2 ultrasound in the diagnosis of single cystic hydatid disease was 96%, the specificity was 98%, and the sensitivity of CT in the diagnosis of single cystic hydatid disease was 80%. The sensitivity of four diagnosis of echinococcosis with echinococcosis was 86%. The sensitivity of 72.00%. ultrasound and hydatid test was 82%, the specificity of specificity was 100%.CT and hydatid test, the sensitivity was 70%, and the specificity was 82%.3 rEgAgB1 as antiprimitive to the serum of 25 cases of children with hepatic cystic echinococcosis. The results of IgG1 specific antibody test showed that 19 cases were positive, and the positive rate of serum diagnosis was 76%. for 25 normal children. The serum diagnosis was not positive and the specificity was 100%. The serum specific antibody of 25 children with hepatic cystic echinococcosis was detected with rEgAgB1 as antigen. The results showed that 9 cases were positive and serum diagnosis was diagnosed. The positive rate was 36%, 25 cases of normal children serum test, serum diagnosis no positive results, detection specificity of 100%. analysis of 25 cases of pediatric echinococcosis patients clinical data, through single factor independent sample t test and chi square test concluded: age, family, symptoms, the size of echinococcosis and rEgAgB1 in children with hepatic cystic echinococcosis positive no expression. Correlation (P0.05). The two factors in the liver and the other organs were associated with the positive expression of rEgAgB1 in the patients with hepatic cystic echinococcosis (P0.05). Conclusion: (1) the hydatid cyst of the liver cystic echinococcosis in children has unique characteristics. The growth rate is fast, the cyst wall of the hydatid is thin, and the cyst of the hydatid cyst is combined with the cyst of other organs. The incidence of hydatid cyst is high, and hydatid cyst most CE1, hydatid cyst tension, adult prone to rupture, hydatid cyst combined with bile leakage rate is small. Imaging and laboratory examination can clear preoperative diagnosis. External capsule subtotal resection is the first choice, such as most of the lesion in the liver parenchyma, feasible improved internal capsule extirpation, such as surgery, such as surgery. The intraoperative cholangiography can effectively reduce the postoperative residual cavity complications. Abdominal pain, the incidence of postoperative complications in patients with hydatid cyst with biliary tract and pre operation of echinococcosis is significantly higher than that of other patients and may be the influencing factors of postoperative complications; 2. In the differential diagnosis of children's hepatic cystic echinococcosis and simplex In sexual hepatic cysts, ultrasound has high sensitivity and specificity, and should be the first choice. If only for diagnosis, CT should not be used as a routine examination because of its radioactivity. But if surgery is required, it is feasible that CT can identify the relationship between the size and location of the cyst and the vascular biliary tract, and provide evidence for the surgical approach. Immunological examination is an important supplement to the imaging examination, especially in the differential diagnosis capsule. When sexual occupancy is difficult, it can improve the quality of diagnosis; (3) rEgAgB1 is highly specific in the diagnosis of echinococcosis, and can effectively improve the specificity, but the sensitivity is low. The detection of IgG1 subtype antibody is significantly higher than that of the IgG4 subtype antibody. The clinical diagnosis and follow-up value of its clinical diagnosis and follow-up need to be verified in the future.
