Abstract
OBJECTIVE The purpose of our study was to evaluate the use of combined helical CT during arterial portography and CT hepatic arteriography in the preoperative assessment of hepatic metastases from colorectal cancer using a unified CT and angiography system. MATERIALS AND METHODS Fifty-four patients with hepatic metastases from colorectal cancer preoperatively underwent combined CT during arterial portography and CT hepatic arteriography using the unified CT and angiography system. Three radiologists independently and retrospectively reviewed the images of CT during arterial portography alone, CT hepatic arteriography alone, and combined CT during arterial portography and CT hepatic arteriography. Image review was conducted on a segment-by-segment basis; a total of 432 hepatic segments with (n = 103) 118 metastatic tumors ranging in size from 2 to 160 mm (mean, 25.8 mm) and without (n = 329) tumor were reviewed. RESULTS Relative sensitivity of combined CT during arterial portography and CT hepatic arteriography (87%) was higher than that of CT during arterial portography alone (80%, p < 0.0005) and CT hepatic arteriography alone (83%, p < 0.005). Relative specificity of CT hepatic arteriography alone (95%, p < 0.0005) and combined CT during arterial portography and CT hepatic arteriography (96%, p < 0.0001) was higher than that of CT during arterial portography alone (91%). Diagnostic accuracy, determined by a receiver operating characteristic curve analysis, was greater with combined CT during arterial portography and CT hepatic arteriography than with CT during arterial portography alone (p < 0.05) or CT hepatic arteriography alone (p < 0.01). CONCLUSION Using a unified CT and angiography system, we found that combined CT during arterial portography and CT hepatic arteriography significantly raised the detectability of hepatic metastases from colorectal cancer.

Abstract
Nitric oxide (NO) is involved in the mechanism of castor oil-induced diarrhea. This study was performed to elucidate the source of NO. Diarrhea was induced by oral administration of castor oil in rats. Diarrhea was significantly inhibited by the pre-treatment with a relatively selective nerve NO synthase inhibitor, 7-nitroindazole. This effect was attenuated by the treatment with L-arginine. Capsaicin-sensitive afferent nerve degeneration did not affect the diarrhea. N(G)-Nitro-L-arginine methylester significantly inhibited diarrhea even in capsaicin-pretreated rats. These data suggest, at least in part, the involvement of NO from nerves on the diarrhea induced by castor oil in rats.

Abstract
BACKGROUND To investigate nontumorous focal enhancement (FE) with computed tomographic hepatic arteriography (CTHA) and perfusion defect (PD) with computed tomographic arterial portography (CTAP) in pericystic liver tissue. METHODS Incidence, shape, and size of nontumorous FE on CTHA and PD on CTAP were examined in 100 consecutive noncirrhotic and 100 consecutive cirrhotic patients. RESULTS FE was observed on CTHA in 77 noncirrhotic and 61 cirrhotic patients, whereas PD was observed on CTAP in 50 noncirrhotic and 51 cirrhotic patients. When both findings were visualized in both CT studies, the shape of the FE on CTHA was similar to the overlapping PD on CTAP in 81% of patients but was larger in 92% of patients. CONCLUSIONS FE on CTHA and PD on CTAP are frequently noted in pericystic liver tissue. The size of FE on CTHA is often larger than PD on CTAP, although the shapes are generally the same. Size discrepancy suggests the presence of both portal supply and splanchnic venous drainage.

Abstract
The correlation between an aberrant pancreaticoduodenal vein and a portal perfusion defect in the dorsal part of segment IV as demonstrated on CT arterial portography (CTAP) was investigated. 14 patients with non-tumorous defects of portal perfusion in the dorsal part of segment IV of the liver parenchyma, shown on CTAP underwent CT during pancreaticoduodenal arteriography. The defect on CTAP was shown as an enhanced area resulting from non-portal venous inflow in eight (57%) of 14 patients on CT during pancreaticoduodenal arteriography. In conclusion, the non-portal venous supply via an aberrant pancreaticoduodenal vein occasionally causes a defect of portal perfusion in the dorsal part of segment IV on CT arterial portography.

Abstract
OBJECTIVE We investigated the cause of nontumorous defects of portal perfusion in the hepatic hilum revealed by CT during arterial portography (CTAP). MATERIALS AND METHODS One hundred sixty patients who simultaneously underwent CTAP and CT during hepatic arteriography of the common hepatic artery formed the basis of our study. The frequency, site, and shape of nontumorous defects of portal perfusion in the hepatic hilum on CTAP and the findings on CT during hepatic arteriography were determined. In 13 patients in whom nontumorous portal perfusion defects were observed on CTAP, CT was performed during selective angiography via the gastric artery, pancreaticoduodenal artery, or both. RESULTS Nontumorous defects of portal perfusion were detected in 49 regions in 33 of the 160 patients (dorsum of segment IV, n = 30; dorsum of the lateral segment, n = 11; segment I, n = 8). Of the 33 patients, 16 had two defects each. Of the 49 nontumorous defects of portal perfusion, 38 showed enhancement on CT during hepatic arteriography. In the 13 patients who underwent CT during selective arteriography, enhancement due to nonportal venous inflow was seen in 16 of the 19 areas of decreased nontumorous portal perfusion (dorsum of segment IV, nine of 11; dorsum of the lateral segment, four of five; segment I, three of three). CONCLUSION The main cause of nontumorous defects of portal perfusion in the hepatic hilum revealed by CTAP is decreased portal inflow due to nonportal supply via the parabiliary venous system. Thus, such lesions were also enhanced at a high frequency on CT during hepatic arteriography.

Abstract
Recently published guidelines for the treatment of dyspepsia have emphasized the importance of age, Helicobacter pylori infection, and alarm symptoms such as weight loss, anemia, and dysphagia in patient assessment. However, the currently available guidelines were not designed specifically for regions in which the incidence of gastric cancer is high, as is the case in Japan, and could lead to cases of gastric cancer being missed at a stage when they are treatable. Therefore a Japanese working group was organized to consider the design of dyspepsia treatment guidelines in Japan, with specific attention to the problem of gastric cancer and the lack of health insurance coverage for H pylori testing and eradication in Japan. To date, the group has prepared and tested clinically the feasibility of two drafts of the guidelines, and has incorporated a number of features and risk factors not currently included in other guidelines for dyspepsia treatment. This article describes the development of the guidelines and their provision of a rational basis for the management of patients with dyspepsia.

Abstract
We describe an extremely rare case of granulocytic sarcoma of the porta hepatis causing obstructive jaundice. The patient was an 84-year-old man admitted because of obstructive jaundice. Ultrasonography (US) and computed tomography (CT) scanning of the abdomen disclosed a mass about 2.5 cm in diameter near the neck of the gallbladder, and thickening of the gallbladder wall. Based on these findings, gallbladder carcinoma was suspected. After endoscopic retrograde biliary drainage (ERBD) was performed, the jaundice resolved. However, blast cells were detected in the peripheral blood 51 days after admission, and laboratory studies disclosed acute myelocytic leukemia (AML: French-American-British [FAB] type M0). We treated him conservatively, with antibiotics and ERBD but he died of disseminated intravascular coagulation. Autopsy showed that the suspected gallbladder carcinoma was actually a granulocytic sarcoma arising in association with AML and causing obstructive jaundice. The largest tumor involved the porta hepatis. It should be kept in mind that granuloctyic sarcoma is a possible cause of obstructive jaundice, even in patients with no evidence of AML.

Abstract
To clarify the mechanism of castor oil-induced diarrhea, this study was performed by using rats in relation to nitric oxide (NO) and prostaglandin (PG). Castor oil induced diarrhea in all rats within 3 hr in the control group. The pretreatment of NG-nitro-L-arginine methyl ester prevented the diarrhea, and this effect was attenuated by the combined treatment of L-arginine. Amino-guanidine inhibiting inducible NO synthase had no effect on the diarrhea, but dexamethasone, an inhibitor of both inducible NO synthase and phospholipase A2 that synthesizes PGs, significantly prevented it. Indomethacin, an inhibitor of cyclooxygenase that synthesizes PGs, also significantly prevented diarrhea. Therefore, the mechanism of the preventive effect by dexamethazone on diarrhea was suggested to be the inhibition of PGs generation. From the above results, it became clear that PG and NO, especially that synthesized by constitutive NO synthase, are involved in the mechanism of diarrhea induction by castor oil in rats.

Abstract
Twelve cases, including varicose veins (7), deep venous thrombosis (3), A-V malformation (1) and skin ulcer (1), were examined by three-dimensional CT venography (3D CTV), and comparison was made with conventional ascending venography. In the "double phase method," the first phase scan (40 seconds) of the femoral region was performed in order to rule out deep venous thrombosis, and the second phase scan (30 seconds) of the lower leg was performed to visualize varicose veins. Veins of the thigh and popliteal space were relatively well visualized. It is thought that 3D-CTV is particularly useful for spatially evaluating deep venous thrombosis and varicose veins.

Abstract
We examined the correlation between the incidence of Crohn disease and dietary change in a relatively homogeneous Japanese population. The incidence and daily intake of each dietary component were compared annually from 1966 to 1985. The univariate analysis showed that the increased incidence of Crohn disease was strongly (P < 0.001) correlated with increased dietary intake of total fat (r = 0.919). animal fat (r = 0.880), n-6 polyunsaturated fatty acids (r = 0.883), animal protein (r = 0.908), milk protein (r = 0.924), and the ratio of n-6 to n-3 fatty acid intake (r = 0.792). It was less correlated with intake of total protein (r = 0.482, P < 0.05), was not correlated with intake of fish protein (r = 0.055, P > 0.1), and was inversely correlated with intake of vegetable protein (r = -0.941, P < 0.001). The multivariate analysis showed that increased intake of animal protein was the strongest independent factor with a weaker second factor, an increased ration of n-6 to n-3 polyunsaturated fatty acids. The present study in association with reported clinical studies suggests that increased dietary intake of animal protein and n-6 polyunsaturated fatty acids with less n-3 polyunsaturated fatty acids may contribute to the development of Crohn disease.

Abstract
A 51-year-old man with posthepatitis cirrhosis underwent a transjugular intrahepatic portosystemic shunt (TIPS) for bleeding of recurrent esophageal varices. The patient had a coexisting, spontaneous, splenorenal shunt. He subsequently developed hepatic encephalopathy, presumably due to excessive portosystemic shunting. Since medical management resulted in no significant improvement, the splenorenal shunt was embolized from the jugular vein approach via renal vein access during temporary balloon occlusion. Within a few days, the patient's hepatic encephalopathy resolved. Twelve months later the patient showed no recurrence of encephalopathy and had maintained a patent TIPS.

Abstract
We investigated the therapeutic efficacy of n-3 polyunsaturated fatty acids (PUFAs) on trinitro-benzene sulfonic acid (TNBS)-induced colitis in the rats, which condition is considered an experimental Crohn's disease (CD). In rats with TNBS-induced colitis, feeding with an elemental diet (ED) plus 2% n-3 PUEA-rich perilla oil significantly suppressed plasma leukotriene (LT) B4 and ulcer index compared to that in rats fed with ED plus 2% n-6 PUFA-rich safflower oil (34.2 +/- 12.3 s 63.8 +/- 13.2 pg/ml and 8.8 +/- 12.1 vs 66.4 +/- 33.1, P < 0.01, respectively). Moreover, the plasma LTB4 and the ulcer index were significantly correlated (P < 0.05). Feeding with ED plus 2% alpha-linolenic acid (A-LA)-rich vegetable oil significantly reduced plasma LTB4 and colonic weight compared to that in rats fed with ED plus 2% eicosapentaenoic acid (EPA)/docosahexaenonic acid (DHA)-rich fish oil in this model (61.6 +/- 10.5 vs 85.0 +/- 20.9 pg/ml and 0.83 +/- 0.13 vs 0.96 +/- 0.08g, P < 0.05, respectively). This study suggested that dietary fat manipulation with perilla oil can reduce colonic damage and that this is correlated with the suppression of plasma LTB4. The therapeutic efficacy of A-LA in controlling intestinal inflammation in experimental CD may be superior to that of EPA and DHA.

Abstract
Crohn's disease (CD) often flares up and requires frequent hospitalization and/or surgery. Cyclic home elemental enteral alimentation (C-HEEA) was developed to prevent flare-up of CD and to minimize patient hospitalization. However, its therapeutic efficacy has not been studied in a large patient population. Therefore, questionnaires were sent to members of the Inflammatory Bowel Disease (IBD) Research Group of Japan to evaluate the therapeutic efficacy of C-HEEA and to define the factors that may affect the efficacy of the treatment. Data for 410 patients (C-HEEA-treated n = 322; drug-treated n = 88) were collected from 29 institutions and analysis showed the following results. The cumulative remission and non-hospitalization rates of the C-HEEA treated group were significantly higher than the rates of the drug-treated group in all patients and in those with ileitis and ileo-colitis (P < 0.0001, P < 0.001, and P < 0.01, respectively), but no significant difference was noted in patients with colitis. Cumulative remission and non-hospitalization rates were also influenced by the daily calorie content of the elemental diet (ED); more than 1200 kcal of the ED per day was found to be more effective than lower amounts to maintain remission and to prevent hospitalization. The therapeutic efficacy of C-HEEA was shown to be superior to that of drug treatment in patients with CD with ileal involvement, and it is suggested that more than 1200kcal per day should be supplied by the ED to enhance its therapeutic efficacy.

Abstract
A newly developed method of spiral computed tomography (CT) angiography was employed for 19 consecutive hepatocellular carcinoma (HCC) patients who underwent hepatectomy. Fine images of the intrahepatic vascular structure, portal venous branches and hepatic veins, and HCC nodules were obtained in 16 patients. A more accurate and easier understanding of the relationship between the intrahepatic vascular structure and the HCC nodules was provided by this spiral CT angiography compared with any other imaging modality.

Abstract
Radiation hepatitis is clearly demonstrated by noncontrast and contrast enhanced CT following radiotherapy for liver diseases. Radiation hepatitis is dependent on dose distribution and is usually demonstrated as a non-segmental bandlike lesion after photon therapy. We report a case of focused, oval-shaped radiation hepatitis that was induced by photon therapy. The attenuation difference was localized in a high-dose area caused by Bragg-peak proton therapy.

Abstract
We evaluated the preoperative CT findings in 10 patients with colon carcinoma in whom peritoneal metastases had been surgically confirmed. Seven patients lacked ascites. No CT findings suggestive of peritoneal metastasis were observed in two patients without ascites even by retrospective evaluation. A large mass was observed in the cul-de-sac in another. In the remaining four patients, small peritoneal metastases ranging from 8 to 11 mm in diameter were observed at the omentum in two, along the falciform ligament in one, and at both the omentum and the iliac fossa in one; three of these patients had received no prospective diagnosis of peritoneal metastasis prior to the surgery. In patients with advanced colon carcinoma with suspected serosal invasion, the entire peritoneal cavity should be carefully examined and interpreted using CT in order to detect small peritoneal implants even when ascites is absent.

Abstract
Sleeve resection of the pulmonary artery, followed by reconstruction with or without bronchoplasty, for bronchogenic carcinoma located at a major lobar orifice has been reported as an alternative to pneumonectomy in patients with poor respiratory functional reserve. We describe herein what is, to our knowledge, the first report of a successful pulmonary arterial reconstruction using a saphenous vein autograft. This operation was performed in a 63-year-old man with poor pulmonary functional reserve who was diagnosed as having a large bronchogenic cancer in the left lower lobe of the lung, located close to the pulmonary hilum. First, a left lower lobectomy was performed with segmental resection of the pulmonary artery, from the basal artery to the lingular artery, after which pulmonary arterial continuity was reconstructed using a saphenous vein autograft. The patient had an uneventful recovery and remains well without any sign of recurrence 4 months after his operation.
