Nine surgically proven congenital absence of gallbladder (CAGB) cases were reviewed. All of them had one or more kinds of biliary symptom. Tests such as abdominal ultrasonography, intravenous or oral cholecystography and even endoscopic retrograde cholangiography not only failed to predict CAGB but misleadingly indicated other similar conditions. Only the abdominal computed tomography (CT), performed on one patient, enabled the accurate diagnosis of CAGB. All the patients underwent abdominal exploration, and CAGB was confirmed by the meticulous dissection of the entire extrahepatic biliary tree and the operative cholangiography. Five patients had concomitant biliary pathologies responsible for their symptoms, but four patients had isolated CAGB. CAGB is a rarely encountered condition for a clinician, but extensive diagnostic work-ups including abdominal CT should be performed in all situations where CAGB is suspected. Thus unnecessary exploration can be avoided in the isolated CAGB case.

Ultrasound-guided percutaneous radiofrequency (RF) ablation has become one of the most promising local cancer therapies for both resectable and nonresectable hepatic tumors. Although RF ablation is a safe and effective technique for the treatment of liver tumors, the outcome of treatment can be closely related to the location and shape of the tumors. There may be difficulties with RF ablation of tumors that are adjacent to large vessels or extrahepatic heat-vulnerable organs and tumors in the caudate lobe, possibly resulting in major complications or treatment failure. Thus, a number of strategies have been developed to overcome these challenges, which include artificial ascites, needle track ablation, fusion imaging guidance, parallel targeting, bypass targeting, etc. Operators need to use the right strategy in the right situation to avoid the possibility of complications and incomplete thermal tissue destruction; with the right strategy, RF ablation can be performed successfully, even for hepatic tumors in high-risk locations. This article offers technical strategies that can be used to effectively perform RF ablation as well as to minimize possible complications related to the procedure with representative cases and schematic illustrations.

OBJECTIVE:
To evaluate the risk of hepatectomy by detecting liver functional reserve preoperatively for patients with primary hepatolithiasis.
METHODS:
The clinical data of 134 patients with primary hepatolithiasis who underwent hepatectomy were reviewed. In terms of evaluation methods for preoperative liver functional reserve they were divided into a Child-Pugh group (group CP) and an indocyanine green group (group ICG). The preoperative and intraoperative parameters, and the incidence of postoperative complications were analyzed.
RESULTS:
Liver failure was more common in group CP (12.85%) than that in group ICG (1.56%, P<0.05). The overall complication rate in group CP (37.14%) was higher than in group ICG (18.75%, P<0.05).
CONCLUSION
ICG15 retention test is more accurate in evaluating liver functional reserve than Child-Pugh scoring system. It may predict the postoperative liver failure in patients with primary hepatolithiasis undergoing hepatectomy, decrease postoperative complications, and increase operation safety.

5.Magnetic resonance imaging for diagnosis of mid- and long-term complication after liver transplantation.
Journal of Southern Medical University 2006;26(5):651-653
OBJECTIVETo assess the value of magnetic resonance imaging (MRI) in mid- and long-term complication monitoring after liver transplantation.
METHODSTwenty-one recipients receiving orthotropic liver transplantation between Feb 2003 and May 2005 were enrolled in this study. FLASH T(1)-weighted, T(2)-weighted fast spin echo, T(2)-weighted fat suppression, dynamic gadolinium-enhanced, MR cholangiopancreatography (MRCP) and three-dimensional dynamic gadolinium-enhanced FISP MRA images were obtained.
RESULTSOf the 21 patients, bile duct complications were detected in all cases and liver arterial and venous complications in 8 cases. Liver cancer relapse occurred in 5 cases and allograft failure in 4.
CONCLUSIONMR imaging allows effective monitoring of mid- and long-term complications of liver transplantation, which provides valuable clues for their clinical treatment.

This study describes the first case of biliary peritonitis after radiofrequency ablation diagnosed by magnetic resonance (MR) imaging with gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid (Gd-EOB-DTPA), a hepatocyte-specific MR imaging contrast agent. The image acquired 300 minutes after the administration of Gd-EOB-DTPA was useful to make a definite diagnosis and to identify the pathway of bile leakage. It is important to decide on the acquisition timing with consideration of the predicted location of bile duct injury.
