OBJECTIVES: The aim of this study is to evaluate the practical role of 3D-CTA in planning the surgery for intracranial aneurysm from a viewpoint of operator. METHODS: Since May 1997 to April 1998, a total of 65 patients who were suspected to have intracranial aneurysms were studied with 3D-CTA using a General Electric Hispeed Advantage helical scanner. Conventional intraarterial digital subtraction angiographies(IA-DSAs) were performed in all patients except four who were in urgent situation. With the images obtained from the 3D-CTA, we performed preoperative assessments for the targeted aneurysms and evaluated its usefulness for planning the aneurysm surgery. RESULTS: 3D-CTA revealed 69 intracranial aneurysms in 55 patients and the size of aneurysms detected were 2-17mm in diameter. The sensitivity of 3D-CTA(95.8%) which was based on the comparison with IA-DSA and supplemented by microsurgical finding was similar to that of IA-DSA(94.1%) and its specificity(81.8%) was lower than that of IA-DSA(100%). Time consuming for getting images from 3D-CTA was no more than 20 minutes and this rapidity was very useful in the emergent situation such as cases of large intracerebral hematoma or massive intraventricular hemorrhage. 3D-CTA proffered various perspective views including surgical view, which were valuable to estimate the degree of head rotation and the direction of clip insertion and to determine the permanent clip type preoperatively. Careful reviewing of 3D-CTA made it possible to minimize surgical procedures. We could omit routine rectus gyrus resection in twelve of 16 surgeries for A-com aneurysm and could operate sixteen of 19 ICA aneurysms successfully without routine extracranial carotid artery preparation. On the basis of 3D-CTA, we could select the appropriate surgical approach in cases of ophthalmic aneurysm or posterior circulation aneurysm. Moreover, in cases of bilateral multiple aneurysms, 3D-CTA was helpful for evaluating the possibility of visualizing contralateral aneurysm through unilateral approach. The extent of bone work could be determined preoperatively through reviewing the 3D-CTA images and possible rupture of MCA aneurysm during bone work could be avoidable. However, 3D-CTA had some limitations for the describing fine vascular architecture such as the teat of aneurysm, a clue for the ruptured aneurysm in multiple aneurysms and most of fine caliber vessels such as hypoplastic posterior communicating artery or anterior choroidal artery was missed on the 3D-CTA. 3D-CTA lacked description for the hemodynamics of cerebral circulation. CONCLUSIONS: Although the 3D-CTA is still insufficient to be the complete substitute for conventional intraarterial digital subtraction angiography, it may be excellent adjunctive tool in planning the surgery of intracranial aneurysm considering that understanding the exact relationship of aneurysm with surrounding structure is mandatory for minimizing the possible risk during surgery.

Bleeding duodenal varices are a rare complication in patients with portal hypertension. Cirrhosis followed by portal vein obstruction and splenic vein obstruction are the most common causes. Although the prognosis of bleeding duodenal varices is usually poor, an awareness of its characteristic presentation may enable diagnostic and therapeutic proce- dures to be performed rapidly with an increased likelihood of a reaching successful out- come. In this study, we report a case of bleeding duodenal varices in a 23-year-old woman with idiopathic portal hypertension who was also suffering with recurrent melena. Panendoscopy identified prominant tortuous varices with central erosion in the 3rd portion of the duodenum and no esophageal and gastric varices. The varices were successfully treated by distal splenorenal shunt.

A choledochocele is a cyst like herniation of the intramural segment of the distal common bile duct protruding into the duodenal lumen. It is controversial whether this disease entity represents a type III variation of a choledochal cyst or an acquired lesion due to a calculus, papillitis or sphincter of Oddi dysfunction. The choledochocele is the rarest form of choledochal cysts and represents only 1.4-5.0% of all choledochal cysts. The diagnosis of choledochocele can be confirmed with certainly using a cholangiography. During a side viewing duodenoscopy followed by retrograde cholangiopancreatography, the mucosa appears normal but the papilla may be larger than usual. When probing the choledochocele with a cannulating catheter, its surface may be appear to be soft and compressible, similar to the pillow sign. After contrast dye is instilled into the bile duct, a round, cyst-like contrast filled structure can be identified adjacent to the terminatian of the common bile duct and an air halo sign may be visible around it. The established treatment of choledochocele is surgical resection of the cyst with anastomosis of the common bile duct to the small intestine, but transduodenal sphincteroplasty or endoscopic sphincterotomy has been advocated as an alternative to excision because of the very low risk of malignant degeneration, operative complications and morbidity. The choice of therapy for the patients with symptomatic choledochchocele is to establish effective drainage of the common bile duct and pancreatic duct. The objective can be achieved using an endoscopic sphincterotomy or transduodenal sphinateroplasy. It has been determined in recent years that endoscopic sphincterotomy is v effective and often followed by a positive prognosis. We report two patients with reicurrent pancreatitis and the common bile duct dilatation secondary to a choledochoce]e, who were treated effectively by endoscopic sphincterotomy.

BACKGROUND/AIMS: Biphenyl dimethyl dicarboxylate (DDB) combined with garlic oil (pennel) has been used to treat chronic liver disease. A randomized, double-blind, active- and placebo-controlled clinical trial was conducted to investigate the efficacy, safety and quality of life in chronic liver disease patients. METHODS: A total of 237 patients with chronic liver disease were randomized into three groups; 100 patients were administered pennel, 102 patients Legalon as an active-control and 35 patients placebo for 12 weeks. The primary endpoint was the rate of alanine aminotransferase (ALT) normalization. We assessed differences in ALT levels and malondialdehyde (MDA) as an oxidative biomarker between 0 and 12 weeks, the improvement in quality of life using a chronic liver disease questionnaire (CLDQ) and the incidence of adverse events. RESULTS: Among 237 patients, there were 157 patients with non-alcoholic fatty liver disease, 36 patients with alcoholic liver disease, and 28 patients with chronic hepatitis B and C. The incidence of ALT normalization at 12 weeks was 89% for the pennel group, 18.6% for the active-control group, and 22.9% for the placebo-control group (p < 0.001). The difference in serum ALT level between 0 and 12 weeks was significantly higher in the pennel group (p < 0.001) and the level of MDA was decreased in the pennel group, statistically (p < 0.001). There was no difference in incidence of adverse events among groups. The pennel group showed significant improvement based on the CLDQ (p < 0.001). CONCLUSIONS: Pennel can effectively improve the rate of ALT normalization and the quality of life with a safety profile in chronic liver disease.
