RESUMO
Objective:To compare the impact of different portal exposure techniques in the Kasai surgery on children with type Ⅲ. biliary atresia during their different perioperative periods.Methods:A retrospective study was performed on the data of children with type Ⅲ. biliary atresia who underwent Kasai surgery at Fujian Children's Hospital from January 2017 to October 2020. Of 45 children enrolled in this study, there were 24 males and 21 females, aged (71.3±21.0) days. Patients who had left and right branches of the portal vein and the left and right hepatic arteries in the portal area being completely freed and elastically stretched during the Kasai operation were included into the free group ( n=22) and the remaining patients were included in the control group ( n=23). Postoperative hospital stay, postoperative direct bilirubin levels, postoperative complications and transplant-free survival after the Kasai operation were compared between the 2 groups. Results:Postoperative hospital stay of (17.1±4.4) d in the free group was significantly lower than that in the control group (20.1±5.4) d, ( t=2.07, P=0.044). The direct bilirubin level at 3 months after surgery for the control group was 30.0 (109, 108.0)μmol/L, which was significantly higher than that of 14.5 (4.0, 37.5) μmol/L in the free group ( Z=-2.16, P=0.031). Twenty-one patients (91.3%) in the control group had frequent attacks of postoperative cholangitis, compared with 13 patients (59.1%) in the free group. The difference was statistically significant (χ 2=4.69, P=0.030). Eleven surviving patients (47.8%) in the control group did not undergo liver transplantation at one year after surgery, compared with 15 patients (68.2%) in the free group. At two years after surgery, 7 surviving patients (30.4%) in the control group did not undergo liver transplantation compared with 10 patients (45.5%) in the free group. Conclusion:For children with type Ⅲ. biliary atresia, completely freeing the left and right branches of portal vein, and left and right hepatic arteries in the liver portal area, and elastically stretching these vessels to expose the portal area of the liver during Kasai surgery increased surgical safety and reduced hospital stay.
RESUMO
Objective To study the X-ray features and differential diagnosis of duodenal obstruction in neonates.Methods X-ray data of duodenal obstruction in 52 cases confirmed surgically were analyzed retrospectively.Erect abdominal plain films were done in each case;Upper gastric intestinal investigations(UGI) were performed in 28 cases,and barium or meglumine diatyizoate enemas were done in 36 cases.Results On the plain films,9 cases with single-bubble,29 with double-bubble,6 with tri-tubble,8 with multiple stepladder-like gas-fluid level in the bowel loops were noted.14 cases with completive obstruction and 13 cases with partial obstruction were found in UGI series.Malposition of the jejunum was seen in 8 cases among them.Abnormal location of cecum on barium enema was demonstrated in 30 cases,included 10 cases of microcolon.The etiology of duodenal obstruction included intestinal malrotation 34 cases,duodenal atresia 9 cases,duodenal stenosis 4 cases and anaular pancreas 5 cases.Conclusion Most cases of duodenal obstruction can be diagnosed with plain films combining with clinical materials.Differential diagnosis should be made by UGI series and barium enema.
