“…77 Intraoperative cholangiography is still the best way to evaluate the donor biliary tract. Noninvasive studies (MRC or CT) do not yet reliably image the smaller ducts, 78,79 and the morbidity of endoscopic retrograde cholangiopancreatography is too high to justify its routine use. 80 Inadequate drainage of a segment, either in the donor or recipient, can result in atrophy of the segment or infectious complications.…”

The continuing shortage of organs for adult transplant recipients has generated enthusiasm for adult-to-adult living donor liver transplantation (LDLT). The major concern has been the ability to resect a graft of adequate size without subjecting the donor to undue risk. The right hepatic lobe is generally large enough for adult recipients, but because of the real and perceived risks of right lobe (RL) resection, surgeons have been hesitant to offer this option to their patients. The first series of RL resections that included a significant number of patients was reported in 1999, and the results were encouraging. Only minor complications occurred in donors, and the recipients fared quite well. Enthusiasm for these donor resections is growing, and more centers are beginning to perform them. There is a good deal of global experience with pediatric LDLT but little with adults, and there are unique considerations in this population. This review examines donor selection criteria for adult recipients, highlights technical points critical for good outcome, and examines the early results and complications in both donors and recipients. If the preliminary results continue to be reproduced, RL LDLT could have significant impact on the worsening organ shortage.

“…CTVEGB can clearly show the size, configuration, location, surface and base of gallbladder polyps in accordance with color ultrasound, [1][2][3][4][5][6][7] , is capable of detecting biliary calculus, tumor, anomaly and dilatation of the biliary tract and protruding lesions with a bigger size. However, limited by the concentration of contrast medium, small polypous lesions are easily obscured and thus escaping detection by OCCT.…”

“…Axial CT data could be reconstructed into two-dimensional multi-planar or three-dimensional (3D) volume-rendered images using workstations and imagerendering software [1] . This CT technology combined with the administration of IV cholangiographic contrast agents could produce diagnostic images of the biliary tract [2][3][4][5][6][7]9,10,14] , and has been used for diagnosis of obstructive biliary disease, choledochocele, choledocholithiasis and aberrance bile ducts. The main limitation of this technique is that the rate of allergic reactions and renal or hepatic toxicity (or both) are relatively high due to by these contrast agents.…”

“…Since Klein et al [1] in 1993 reported the computed tomographic cholangiography using spiral scanning and 3D image processing, many lesions of the biliary tract have been studied [2][3][4][5][6][7][8][9][10][11][12][13][14] . In 1994 CT virtual endoscopy (CTVE) was introduced, its application in obtaining organ images has been described extensively [15][16][17][18][19][20][21][22][23][24][25][26][27][28] .…”

AIM:CT virtual endoscopy has been used in the study of various organs of body including the biliary tract, however, CT virtual endoseopy in diagnosis of gallbladder polyps has not yet been reported. This study was to evaluate the diagnostic value of CT virtual endoscopy in polyps of the gallbladder. METHODS:Thirty-two cases of gallbladder polyps were examined by CT virtual endoscopy, ultrasound, CT scan with oral biliary contrast separately and confirmed by operation and pathology. CT biliary cystoscopic findings were analyzed and compared with those of ultrasound and CT scan with oral biliary contrast, and evaluated in comparison with operative and pathologic findings in all cases. RESULTS:The detection rate of gallbladder polyps was 93.8%(90/96), 96.9%(93/96) and 79.2%(76/96) for CT cystoscopy, ultrasound and CT scan with oral contrast, respectively. CT biliary cystoscopy corresponded well with ultrasound as well as pathology in demonstrating the location, size and configuration of polyps. CT endoscopy was superior to ultrasound in viewing the polyps in a more precise way, 3 dimensionally from any angle in space, and showing the surface in details. CT biliary cystoscopy was also superior to CT scan with oral biliary contrast in terms of observation of the base of polyps for the presence of a pedicle, detection rates as well as image quality. The smallest polyp detected by CT biliary cystoscopy was measured 1.5 mm×2.2 mm×2.5 mm. CONCLUSION:CT biliary cystoscopy is a non-invasive and accurate technique for diagnosis and management of gallbladder polyps.

“…Used widely prior to 1980s, percutaneous transhepatic cholangiographic (PTC) was an established technique for diagnosis of bile duct obstructive diseases (6,7). With the introduction of advanced CT and MRI technologies, particularly with the application of MR cholangiography (MRC), ERCP and PTC are used surrounding structures and between bile and most hypodense stones (12). CT cholangiography has not been commonly used due to the low resolution of single detector CT in the past and reports of adverse events after injection of biliary contrast agent (13,14).…”

Purpose: To explore the technical feasibility of double contrast percutaneous transhepatic cholangiographic CT (DC-PCT-CT) in patients with bile duct obstruction. Methods: Seven patients with bile duct obstructive diseases were studied, including 5 males and 3 females, ranging in age from 24 yrs to 74 yrs (average: 47.7 yrs). There were 5 cases of hilar cholangiocarcinoma, 1 case of sclerosing cholangitis, and 1 case of malignant transformation of adenoma at the distal end of the common bile duct. PTC was carried out initially, involving injection of 30ml 4.5-6.0mgI iohexol. After the bile duct system was filled, CT scan was performed, and further followed by enhanced CT with intravenous injection of 300mgI/ml contrast agent. Arterial phase, venous phase, and parenchymal phase acquisitions were obtained. Raw CT images were viewed and multiplanar reconstruction (MPR), maximum intensity projection (MIP), and volume rendering (VR) image post-processing were performed. Results: DC-PCT-CT was performed successfully and bile duct drainage was carried out. Mild lesion enhancement was demonstrated in three cases in arterial phase, while all seven cases demonstrated enhancement of various degrees in venous phase. The lesions lead to track-like, asymmetrical or irregular bile duct obstructive narrowing, and in one case intra-luminal filling defect. Reliable diagnosis was suggested in all cases. MPR, MIP and VR images were useful in demonstrating precise lesion location and for surgical planning. Conclusion: In patients with bile duct obstruction, DC-PTC-CT is a feasible technique offering both important diagnostic value and drainage application.
