Objective:To evaluate the value of prenatal ultrasound in localization, qualitative diagnosis and prognosis of adrenal mass in fetus.Methods:According to the pathological and follow-up results, the clinical data, ultrasonographic features and prognostic results of 43 cases of fetal adrenal mass in Changsha Maternal and Child Health Hospital were collected and analyzed, and statistical analysis was performed.Results:In this group, 43 cases of adrenal mass lesions were detected by prenatal ultrasound in 172 561 fetuses, with a detection rate of 2.49/10 000 (43/172 561). There were 19 cases of adrenal hematoma (5 cases were not excluded as adrenal neuroblastoma), 10 cases of subphrenic free lung, 8 cases of adrenal cyst, 3 cases of adrenal neuroblastoma, and 3 cases of adrenal teratoma. The coincidence rate of prenatal ultrasound diagnosis was 100%. The gestational weeks of isolated lung were earlier than those of neuroblastoma, hematoma, teratoma and cyst ( P=0.035, 0.031, 0.043, 0.025), but there was no significant difference among other groups ( P>0.05). There was no significant difference in tumor diameter among the groups ( P>0.05). The initial finding of subphrenic free lung was the earliest at the gestational week, 43 fetused were born, 18 cases were treated with surgery, 24 cases were observed, 1 case was abandoned for treatment, follow-up found that the prognosis of the other cases were good except for 1 death. Conclusions:Prenatal ultrasound has a good advantage in prenatal diagnosis and differential diagnosis of adrenal mass lesions. The overall prognosis of fetal adrenal masss is good.

Objective To summarize the pathology of congenital intestinal atresia,the incidence and prenatal diagnosis rate of different types,and to analyze the location and type of intestinal atresia as well as the factors that affect the mortality of various types of intestinal atresia.Method We retrospectively analyzed the clinical data of 147 children with congenital intestinal atresia from January 2013 to March 2016,including gender,gestational age,parity,prenatal diagnosis or not,delivery methods,hospital admission,surgical methods,findings during surgery,combined malformations,complications and prognosis.They were analyzed statistically.Result A total of 147 cases,including 69 males and 78 females were enrolled.There were 40 premature infants and 107 full term cases.Twins were found in 3 cases.Hospital admission age range from 1 hour to 62 days;admission weight range from 1 480 g to 4 200 g;32 cases were diagnosed before birth.2 cases were abandoned before surgery because of trisomy 21.Postoperatively,the occlusion sites was confirmed as following:67 cases (46.2％) in ileum,43 cases (29.7％) in jejunum,26 cases (17.9％) in duodenum,and 9 cases (6.2％) in colon.The pathological types were as following:type Ⅰ 42 cases (29.0％),type Ⅱ 8 cases (5.5％),type Ⅲa 65 cases (44.8％),type Ⅲb 15 cases (10.3％) and type Ⅳ 15 cases (10.3％).22 cases (14.9％) were died because of refusal of treatment:7 cases were due to short bowel syndrome and meconium peritonitis,6 cases were due to postoperative chronic pseudo-obstruction,and 5 cases had anastomotic leakage requiring reoperation.1 case had postoperative enterocolitis and gave up treatment,1 case had anastomotic leak and sever systemic post-surgery infection and gave up further treatment,and 2 cases gave up because of 21-trisomy syndrome.Conclusion The operation plan of intestinal atresia should be based on the location and type of the blockade;the location and complications of the blockade (pseudo-obstruction,short bowel syndrome,and anastomotic leakage) are important factors affecting the treatment and prognosis.

Objective To investigate the effect of surgical treatment of necrotizing enterocolitis (NEC) with different surgical ages.Methods From January 2014 to December 2017,105 neonates with NEC in our hospital were divided into early operation group (operation age ＜ 7 days,n =47) and late operation group (7 ＜ operation age ＜ 28 days,n =58).The general data,surgical indications,intraoperative conditions,surgical methods,postoperative complications,and postoperative survival rates were compared between the two groups.Results Among the 105 neonates with NEC,74 were male and 31 were female.The average birth weight was (2 398 ± 927)g,and the average gestational age was (35 ± 4)weeks.Compared with the early operation group,the late operation group had lighter birth weight,smaller gestational age and higher rate of respiratory failure (P ＜ 0.05).There was no significant difference between the two groups in the proportion of surgical indications (diffuse peritonitis,pneumoperitoneum,and medical treatment ineffective) (P ＞ 0.05).The necrosis rate of small intestine in the late operation group was higher than that in the early operation group,but the necrosis rate of small intestine and colon was lower than that in the early operation group (P ＜ 0.05).There was no significant difference in the proportions of the two groups in the surgical methods (enterostomy,intestinal resection and anastomosis and enterostom,exploratory laparotomy,abdominal drainage,and intestinal resection and anastomosis) (P ＞ 0.05).The incidence of intestinal stenosis in early operation group was higher than that in late operation group (P ＜ 0.05).The survival rate of early operation group was 78.7％,while that of late operation group was 63.8％,with no significant difference (P ＞ 0.05).Conclusions The patients with NEC who were operated within 1 week after birth are more common in term infants and with colon necrosis,and are more likely to occur intestinal stenosis after surgery.The patients with NEC who were operated after 1 week of birth are more common in prematures and low-birth-weight patients,and are often associated with respiratory failure.Pneumoperitoneum and diffuse peritonitis are common surgical indications for NEC.Enterostomy is the major surgical method.Choosing the right timing and surgical method can improve the prognosis of patients with NEC.
