Bile duct necrosis and liver abscess are rare complications after transcatheter hepatic arterial embolization (THAE) of hepatocellular carcinoma. Authors report bile duct necrosis and liver abscess occurred in 2 cases as a complication of THAE of hepatocellular carcinoma. In these two patients, lipiodol emulsion mixed with adriamycin and mitomycin was used more than three times as chemoembolic materials.

Afferent loop syndrome(ALS) is caused by obstruction of the afferent loop after subtotal gastrectomy with Billroth II gastrojejunostomy. Prompt diagnosis of ALS is important as perforation of the loop occurs. The aim of this study is to ascertain the value of sonography and CT to diagnose ALS. We describe the radiologic findings in ten patients with ALS. The causes of ALS, established at surgery, included cancer recurrence (n=4), internal hernia(n=4), marginal ulcer (n=1), and development of cancer at the anastomosis site(n=1). Abdominal X-ray and sonography were performed in all cases, upper GI series in five cases and computed tomography in two cases. The dilated afferent loop was detected in only two cases out of ten patients in retrospective review of abdominal X-ray. ALS with recurrence of cancer was diagnosed in three cases by upper GI series. Of the cases that had sonography, the afferent loop was seen in the upper abdomen crossing transversely over the midline in all ten patients. The causes of ALS were predicted on the basis of the sonograms in three of the five cancer patients. In two cases of computed tomography, the dilated afferent loop and recurrent cancer at the remnant stomach were seen. Our experience suggests that the diagnosis of afferent loop syndrome can be made on the basis of the typical anatomic location and shape of the dilated bowel loop in both sonography and computed tomography.

The most common causes of conjugated hyperbilirubinemia after the first or second week of life are neonatal hepatitis and biliary atresia. Since these entities represent variable expressions of same pathologic process and have similar clinical, biochemical, and histologic features, differential diagnosis is extremely difficult. We prospectively studied 28 jaundiced infants by sonography and hepatobiliary scintigraphy. Final diagnoses included 12 biliary atresia and 16 neonatal hepatitis. Visualization of a normal-sized common bile duct or gallbladder was compatible with the diagnosis of neonatal hepatitis. Non-visualized or atrophic gallbladder no sonography coupled with non-visualization of bowel activity on scintigraphy was highly suggestive of biliary atresia. We believe that sonography plays valuable role in the initial evaluation of the infants with persistent neonatal jaundice. The combined use of sonography and hepatobiliary scintigraphy provides the most valuable in formation in suspected biliary atresia for prompt surgical treatment.

Journal of the Korean Radiological Society 1986;22(3):384-391
To assess the pathological basis of the sonographic changes of the gallbladder wall in cholecystitis, thesonographic appearances of the gallbladder wall were analysed in 17 patients with acute cholecystitis and 27patients with chronic cholecystitis, and correlated with pathological specimens removed at surgery. In acutecholecystitis, a thin sonolucent layer within the echogenic gallbladder wall corresponds to subserosal edema,hemorrhage and inflammatory cell infiltration: in chronic cholecystitis it corresponds to subserosal edema,hemorrhage and inflammatory cell infiltration: in chronic cholelcystitis it corresponds to subserosal edema,hemorrhage and inflammatory cell infiltration, in chronic cholelcystitis it corresponds to muscular hypertrophy.Indistinctness and/or a low echogenicity rind along the inner margin reflects mucosal sloughing or obliteration ofthe mucosal folds. Uniformly decreased echogenicity of the wall is caused by severe inflammatory cell infiltrationwith sloughing of the mucosa or obliteration of the mucosal folds. These sonographic singns are considered to bevaluable sings of cholecystitis.

The findings of upper gastrointestinal series(UGI), computed tomography (CT), and sonography(US) of ten duodenal adenocarcinoma confirmed by surgery (n=7) and endoscopic biopsy (n=3) were retrospectively analyzed. We performed US in all cases, CT and UGI in 8 out of 10 cases. UGI showed 4 cases of ulcerating type, 3 of stenotic type, and one failed to visualize duodenum due to previous gastrojejunostomy. UGI was more accurate in depicting the mucosal changes such as ulcer, however, it played a limited role in the evaluation of extraluminal extension. US showed 4 cases of hypocchoic wall thickening, 3 of hypoechoic extraluminal mass, and one of polypoid intraluminal mass but 2 were not detected on US. US accurately detected hepatic and pancreatic metastasis, however, it played a limited role in the evaluation of direct colonic invasion. CT showed was eccentric wall thickening in 4 cases, large extraluminal mass in 2, and low density intraluminal mass in but one was missed on CT. CT was the most accurate modality to determine the extent of the lesion and adjacent or distant metastasis but it could be misdiagnosed as submucosal tumor if the extraluminal component is large. UGI, CT and US can be used complementary for accurate diagnosis of a duodenal cancer. US may be used as a screening tool for detecting duodenal cancer.

PURPOSE: Authors retrospectively evaluated the efficacy of superselective renal arterial emboliation in 5 patients with symptomatic renal angiomyolipoma. MATERIALS AND METHODS: Five Patients with renal angiomyolipoma who had been treated with superselective renal arterial embolization were analysed retrospectively. Two patients who had multiple bilateral lesions were associated with tuberous sclerosis. The mbolic materials used were absolute alcohol in 6 sessions, absolute alcohol mixed with lipiodol in one session, and polyvinyl alcohol in one session. RESULTS: We could observe devascularization of the tumor on the post-embolization arteriograms. The symptoms such as flank pain were improved in all patients during the follow-up period of 3 months to 3years. CONCLUSION: Superselective renal arterial embolization is an effective and safe procedure in the management of renal angiomyolipomas.

PURPOSE: To assess the effectiveness and clinical usefulness of prostate biopsy by automated gun biopsy device under the transrectal ultrasonographic guidance, authors analysed the result of biopsy and the patients status after biopsy procedure. METHODS AND MATERIALS: The subjects consisted of 24 patients with prostatic disease. Biopsy instrument was an automated gun biopsy device loaded with an 18 gauze biopsy needle. All the patients were admitted to the hospital. No analgesics was given. All the procedure was performed with the patient in left lateral decubitus. Biopsy was performed at 2-4 different points of the prostate in 22 cases, but recently, six different points were targeted in two patients. RESULTS: Biopsy specimens were sufficient in 21 cases but insufficient in three cases. Histologic examination of biopsy specimens showed that 13 cases were nodular hyperplasia, eight cases were cancerous and three cases were inflammation. There was no clinically significant complication. There was mild to moderate degree of pain in all patients. CONCLUSION: Tansrectal biopsy of the prostate with an automated gun biopsy device under ultrasonographic guidance is considered relatively easy, handy and useful procedure in patients with prostatic disease. The procedure may be performed on the outpatient basis.

PURPOSE: To verify the value of CT in the diagnosis of cirrhosis, CRL ratio was measured in 225 Koreans who had and evidence of cirrhosis both clinically and radiologically. MATERIALS AND METHODS: The mean value of CRL ratio was 0.68+/-0.21 which was significant difterent from the published value of normal person(0.45+/-0.07). The difference of CRL ratio between men and women and that among different age groups were found to be not statistically signficant. RESULTS: CRL ratio of virus- related group(N:149) was 0.64+/-0.18, whereas that of virus-nonrelated group (N=76) was 0.76+/-0.23. There was a statistically significant difference of CRL ratio between virus-related group and virus-nonrelated group. CRL ratio of hepatoma-related group(N:113) was 0.71+/-0.22 whereas that of heparoma-nonrelated group(N:112) was 0.66+/-0.19. There was no statistically significant difference of CRL ratio between hepatoma-related group and hepatoma-nonrelated group. CONCLUSION: Measurement of CRL ratio by CT is a useful method in assessing cirrhosis of the liver.
