Congenital choledochal cyst analysis and diagnosis of spiral CT

Scan-based diagnosis to provide reliable information. Key words children with congenital choledochal cyst body x-ray computed tomography scans of children with congenital choledochal cyst enhancement is an expansion of the liver bile duct syndrome, right upper quadrant mass in children is caused by common causes. Many methods to diagnosis, but CT scan is the most commonly used methods. LO surgeries now confirmed the CT manifestations of congenital bile duct cysts is as follows. 1 Data and methods 1.1 General information collected in this group of children over the years in our hospital in children with congenital choledochal cyst CT data 1O cases, including 4 males and 6 females, aged minimum 4 months, maximum 13 years old . Clinical symptoms and signs are right upper quadrant mass in 9 cases, jaundice in 6 cases,[link widoczny dla zalogowanych], 5 cases of abdominal pain, fever, vomiting and gastrointestinal symptoms in 3 cases. 1.2 The inspection methods used by the U.S. GE, spiral CT, slice thickness 5mm ~ 10mm, all cases underwent enhanced CT scan + scanning. 1.3 The type of lesion type classification using Todani5. 2 Results 2.1 lesion type classification method based on Todani ll1, 10 cases, Ia-type expansion of 7 cases of cystic duct, accounting for 70. O%, Ⅳ a hepatic bile duct in 3 cases of cystic expansion, accounting for 30. O%. 2.2CT sign of scan: Ia-type in 7 patients with solitary cysts, expressed as liver, kidney, pancreatic finishing the round between the edge of the low-density, cystic on the surrounding tissue over to varying degrees. 1 case of multiple, showing multiple low density within the abdominal cavity, clear boundary, sizes, Ia type of cyst fluid in the enhanced scan without enhancement showed a circular thin-walled cyst and homogeneous enhancement; Ⅳ a type of dilated common bile duct wall strengthening and expansion of the intrahepatic bile ducts showed no enhancement,[link widoczny dla zalogowanych], still showed low density, and with the surrounding blood vessels accompanied the liver contrasting. Ⅳ a type showed hilar and intrahepatic cystic low density. 3 Discussion 3.1 The cause of the etiology of congenital choledochal cyst is still controversial, is generally believed that with the common bile duct distal obstruction, bile duct dysplasia,[link widoczny dla zalogowanych], nerve abnormalities, bile duct confluence of abnormalities and other factors. Incidence of women than men, typical symptoms include abdominal mass, jaundice and abdominal pain. 3.2 Typing the current classification of the disease more and more used Todani current classification,[link widoczny dla zalogowanych], this group were also classified here, statistical incidence rate of type Ia choledochal cyst is the highest, accounting for about 80% to 90%. 3l3CT expressed in terms of the common bile duct cyst, CT can directly observe the cyst, the scope and show the relationship between bile duct and liver. CT type Ia show a high specificity, ie liver, kidney, pancreatic finishing the round between the edge of the cystic low density, enhanced scan showed typical features of cystic lesions of the enhancement. Common bile duct often presents with a sudden expansion of the proximal cystic, abrupt termination of the expansion characteristics of the bottom, left and right hepatic duct expansion, the outer weeks bile duct does not expand, therefore, can be distinguished from biliary obstruction. Peripheral bile duct dilatation secondary to its typical performance. 1Va type showed hilar and intrahepatic cystic low density, can significantly expand the proximal left and right, enhanced when the dilated common bile duct wall enhancement, no enhancement in the expansion of the intrahepatic bile duct, manifested as low density, the differential diagnosis The main and secondary bile duct dilatation acquired, liver and abdominal cyst differentiated from cystic lesions. 3.4 Spiral CT diagnosis of choledochal cyst using spiral CT scan of the technical, multi-planar, three-dimensional reconstruction of the image helps to show the expansion of the bile duct,[link widoczny dla zalogowanych], the scope and relationship with surrounding structures, CT is more helpful the type of scan to clear cyst. Post-processing technique using multi-tissue reconstruction, reconstruction of the biliary system, vascular system, and a good show of interest, the use of this technology to show the lesion and surrounding tissue, the overall form of the relationship between the lesions can show the internal situation and details include this in the section may be difficult to find the problem. Lesions can be reconstructed three-dimensional images, three-dimensional view of reflecting the form of cysts, resulting in bionics effect. The above analysis, spiral CT scan of the use of technology has changed the normal CT diagnosis of the disease can only observe the organizational structure and the limitations of lesion cross-sectional images, the lesion can be comprehensive, complete and visually displayed, and thus make the spiral CT for the diagnosis of congenital choledochal cyst is more accurate and more value.
