RESUMO
Objective To evaluate the efficacy of single or double-antibiotic regimen for the treatment of complicated appendicitis in children,with the purpose to guide the rational use of antibiotics in clinic.Methods Six hundred and sixty-three patients with acute appendicitis admitted to the department of pediatric surgery in Jinhua Municipal Central Hospital between March 2011 and February 2015.One hundred and seventy-two of 663 patients with complicated appendicitis which confirmed by intra-operative macroscopic or post-operative pathological examination were eligible for the study.These patients were divided into two groups based on the regimen of their postoperative antibiotics:single or double-antibiotic regimen(treatment group,n=66);triple antibiotics regimen(control group,n=106).Demographic data,blood routine test and C-response protein(CRP),length of hospital stay,postoperative complications and duration of antibiotic treatment were recorded and statistically analyzed.Results There was no difference between the treatment group and control group with respect to age distribution,blood routine examination and CRP, length of hospital stay, duration of antibiotic treatment or postoperative complications.Although the number of patients changed of antibiotics on the basis of bacterial culture of pyogenic fluids in treatment group were more frequently than those in the control group(7/66 vs.1/106), the therapeutic effective rate of changed of antibiotics was 100% in both two groups.The culture positive rate of peritoneal fluids was 72.09% (124/172), the most common pathogens were escherichia coli(80.15%, 105/131),pseudomonas aeruginosa(5.34%,7/131)and klebsiella pneumonia (3.05%,4/131).The results of bacterial culture of peogenic fluids showed no difference in both two groups.Conclusion Children with complicated appendicitis can be managed effectively with single or double broad-spectrum antibiotics after appendectomy,and it may be beneficial to guide the rational use of antibiotics and decrease the irrational use of multi-antibiotics combination in clinic.
RESUMO
Objective To investigate the prenatal diagnosis and postnatal clinical outcomes of fetal congenital choledochal cyst (CCC) to improve the recognition and treatment of fetal CCC.Methods Clinical data of 23 cases of fetal CCC which were diagnosed during routine prenatal ultrasonic examination in Jinhua Municipal Central Hospital from June 2009 to May 2015 were retrospectively analyzzed. Maternal age, gestational age at diagnosis of CCC, location and size of cyst, postnatal examination, age at operation and follow-up outcomes were recorded and statistically analyzed by Wilcoxon rank-sum test.Results (1) Among the 23 cases, six (26%) were terminated and the rest 17 continued their pregnancies (74%). (2) Results of the prenatal ultrasonography of the 23 cases indicated that hepatic portal cysts were closely related to hepatic portal veins or arteries. Six of the cysts communicated with gall bladder and eight connected to intrahepatic bile duct. The maximum diameter of the cysts in the 23 cases was 16.0-31.0 mm, averagely (24.7±3.7) mm. The maximum diameter of cysts diagnosed in the third trimester was significantly larger than that in the second trimester [ 27.0 (22.0-31.0) vs 23.0 (21.0-25.0) mm,Z=-2.134,P<0.05]. (3) Among the 17 cases of continued pregnancy, one underwent cesarean section at 35+ weeks of gestation and 16 delivered at term with the average gestational age at delivery of (38.2±1.1) weeks. All neonates were re-examined by abdominal ultrasound at 1-2 postnatal weeks and confimed prenatal diagnosed of CCC. (4) The 17 neonates were re-examined by abdominal ultrasound during the second postnatal week and the results showed that cyst size remained the same in four, decreased in one and gradually increased with the gestational age in 12 neonates. Among the 16 cases of confirmed CCC, 12 received surgery, including 11 (Ⅰa, 6;Ⅰc, 3;Ⅳb, 2) within one year-old and one (Ⅰc) around 18 months old. The prognosis was uneventful. Four out of the 16 cases rejected surgical operation and were followed up in outpatient. One neonate was diagnosed with congenital biliary atresia and transferred to Children's Hospital for operation.Conclusions When fetal abdominal cyst presented with hepatic portal cyst which communicates with gallbladder or intra-hepatic duct in ultrasonography, a congenital choledochal cyst should be taken into consideration by excluding the possibility of biliary atresia in the first place. Surgery for CCC infants without symptoms or signs is suggested to be performed around three months after birth. The postoperative prognosis of CCC is favorable, so termination is not recommended for gravidas with fetal CCC in prenatal consultation.
RESUMO
Objective To investigate the clinicopathological features and diagnosis of intestinal neu-ronal dysplasia type B.Methods Between January 2004 and August 2014 , 9 patients ( 5 males and 4 females) were treated for constipation and abdominal distention,and in all of them an intestinal neuronal dys-plasia type B was confirmed histopta holoig cally.The age of 9 patients ranged from 3 months to 1 year old ( mean 7.8 months) .The specimen of 9 patients was routinely takne by paraffin-embedded full-circumference sections of lesional bowel,hematoxylin and eosin and immunohits ochemical stainign were carried out on the specimen.The patholgo ical morphology and quantitative of inet stinal en urons and ganglia were retrospectively analyzed.Results Total of the 9 patients,the number and density of myenteric ganglia increased significant-ly increased in the lesional bowel,the pathological findings included giant nerve plexus,isolated and ectopic ganglia.In the proximal bowel,the number and density of myenteric ganglia were observed abnormal on giant nerev plexus, isoal ted and ectopci ganglia was osb erved.Combinated these pathological findings and symp-toms,intestinal neuronal dysplasia type B was diagnosed.Conclusion The diagnosis of ni testinal neuronal dysplasia type B relies on typical presentations of allied disorders of Hirschsprung′s disease,giant ganglia, isolated and ectopic ganglia,and increasing the density of giant submucosal ganglia of pathologic morpholo-gy,meanwhile,excludingo thers prima ry etiologies.
