Hepatic involvement in Wilson disease (WD) manifests as a diffuse chronic disease in the majority of patients. However, in a subset of patients focal liver lesions may develop, presenting with a wide range of imaging features. The majority of focal liver lesions in patients with WD are benign nodules, but there are reports that have described malignant liver tumors or dysplastic nodules in these patients. Because of the possibility of malignant transformation of liver nodules, major concerns have been raised with respect to the management and follow-up of patients with WD in whom focal liver lesions have been identified. The assessment of liver involvement in patients with WD is generally performed with ultrasonography. However, ultrasonography conveys limited specificity so that magnetic resonance (MR) imaging is often performed to improve lesion characterization. This review was performed to illustrate the spectrum of MR imaging features of focal liver lesions that develop in patients with WD. It is assumed that familiarity with the MR imaging presentation of focal liver lesions in WD may help clarify the actual nature of hepatic nodules in patients with this condition. 相似文献

Background
The aims of this study were to assess the efficacy of percutaneous drainage of postoperative abscess after abdominal surgery and to identify factors predictive of failed drainage.Methods
Data from 81 patients with postoperative abdominopelvic abscesses treated with percutaneous drainage were reviewed. Percutaneous drainage failure was considered when surgery was needed to control the sepsis. Predictive variables were sought using univariate and multivariate analyses with logistic regression models.Results
Successful drainage requiring 1 (n = 46) or 2 (n = 17) procedures was observed in 63 patients (78%; 95% confidence interval, 67%–86%). Surgery was needed in 18 patients (22%; 95% confidence interval, 14%–38%). Residual collection after a first percutaneous drainage was the single predictive factor for failed drainage on univariate and multivariate analyses (P = .0275).Conclusions
Percutaneous imaging-guided drainage is a feasible and effective method for the treatment of abdominopelvic abscess, with a success rate of 78%. Residual collection is an independent predictor of unfavorable outcome after percutaneous drainage. 相似文献4.

BACKGROUND: CT has proved to be helpful in patients with acute pancreatitis for differentiating between mild and severe forms. Followup of acute pancreatitis with CT has been advocated but rarely studied. The aim of this study was to determine if late CT performed at day 7 might be helpful in establishing the prognosis or the type of complications, and to select a subgroup of patients in whom CT could be beneficial. STUDY DESIGN: Contrast-enhanced CT was performed at the admission day and 7 days after admission in 102 patients admitted for acute pancreatitis. The extent of pancreatic inflammation was classified according to Balthazar grade, and intrapancreatic necrosis on these examinations was prospectively assessed and compared with clinical and biologic data and with patient outcomes. RESULTS: Among 102 patients, complications developed in 24 (23%). Complications developed in only 8% of patients with Ranson score <2, making routine early CT unnecessary. For the patients with Ranson score <2 and Balthazar grades A and B at day 1 CT, late CT seemed to be useless. Complication was suspected by clinical and biologic tests before day 7 in 22 of 24 complicated patients (92%), suggesting that CT could be proposed only in cases of clinical or biologic deterioration. Late CT was correlated with a complicated course in patients with Balthazar grades D and E or intrapancreatic necrosis >50%. Late CT was predictive of complications in cases of intrapancreatic necrosis enlarging since the first examination. CONCLUSIONS: Our study showed that in acute pancreatitis: 1) there is little justification for systematic early CT, especially in patients with Ranson score <2, and 2) late CT does not need to be performed routinely, but only in cases of clinical or biologic worsening. 相似文献

INTRODUCTION: The aim of this study was to evaluate prospectively the impact of the routine use of abdominal spiral computed tomography (SCT) in patients with postoperative small bowel obstruction (SBO) for whom initial conservative treatment was proposed. PATIENTS AND METHODS: We have compared the management of SBO in patients with clinical stable condition in two successive periods : from 1989 to 1998, 127 patients (preSCT group) for whom management was based on standard clinical-biological-radiological assessment (CBRA) et from 1999 to 2000, 30 patients (SCT group) for whom management included SCT. The decision of surgical team was correlated with the type of small bowel obstruction at laparotomy : closed-loop obstruction without intestinal necrosis (true-positive), intestinal necrosis as a consequence of delayed diagnosis defined as false-negative, diffuse adhesion defined as false-positive et patient non operated defined as true-negative. RESULTS: Among the 127 patients from the preSCT group, 87 were treated conservatively and 40 were operated : SBO with closed-loop obstruction without intestinal necrosis (n = 29,72%), SBO with diffuse adhesion (n = 4, 10%) and SBO with intestinal necrosis (n = 7, 17%). Among the 30 patients from the SCT group, 16 were treated conservatively and 14 were operated: SBO with closed-loop obstruction without intestinal necrosis (n = 8, 57%), SBO with diffuse adhesion (n = 6,43%) and SBO with intestinal necrosis (n = 0,0%; NS). Both groups were similar for rates of patients with SBO with or without necrosis and rate of patients treated conservatively (NS). In SCT group, there was significantly more patients operated for diffuse adhesions (p < 0,01). Negative predictive value of CBRA + TDM was significantly higher than those of CBRA alone (p = 0,041). CONCLUSION: Due to a very high sensibility, TDM increase probably the rate of early laparotomies, maybe unnecessary, in patients without any sign of SBO due to closed-loop obstruction. Thus, systematic use of TDM in patients with clinical suspicion of SBO remains to be evaluated. 相似文献

Crohn's disease is characterized by transmural inflammation and chronic disorder of the gastrointestinal tract. Abdominal complications of Crohn's disease are frequent and quite variable and their diagnosis is commonly performed with CT. The purpose of this article is to review the CT features of the abdominal complications of Crohn's disease, including ileocolitis, abscess, phlegmon, fistula, bowel obstruction, portal vein gas, colonic distention, as well as urinary, hepatobiliary and pancreatic complications. 相似文献

Small-bowel diseases: prospective evaluation of multi-detector row helical CT enteroclysis in 107 consecutive patients 总被引:25,自引:0,他引:25
PURPOSE: To prospectively evaluate multi-detector row helical computed tomographic (CT) enteroclysis for the depiction of small-bowel diseases. MATERIALS AND METHODS: The study group included 107 patients who were suspected of having small-bowel tumor (n = 8), active inflammatory small-bowel disease (n = 18), unexplained gastrointestinal bleeding (n = 36), refractory celiac sprue (n = 14), and low-grade small-bowel obstruction (n = 31). A nasoenteric tube was positioned into the duodenojejunal junction by using fluoroscopic guidance and water was infused with a pressure-controlled pump. After intravenous administration of 120 mL of iodinated contrast material, multi-detector row helical CT enteroclysis images were obtained with 4 x 2.5 mm collimation (four detector rows and 2.5-mm section thickness). Multi-detector row helical CT enteroclysis findings were analyzed by two readers working in consensus. Findings were compared with the results of endoscopy, enteroscopy, videocapsule endoscopy, histopathologic analysis, or clinical follow-up. RESULTS: Multi-detector row helical CT enteroclysis was well tolerated in 106 patients; one patient complained of abdominal pain after the examination. Multi-detector row helical CT enteroclysis allowed the diagnosis of small-bowel masses (n = 21), active Crohn disease (n = 9), small-bowel tuberculosis (n = 2), small-bowel lymphoma complicating celiac disease (n = 4), and confirmed low-grade small-bowel obstruction (n = 12). Multi-detector row helical CT enteroclysis demonstrated normal findings in 60 patients. Sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of multi-detector row helical CT enteroclysis were 100%, 95%, 97%, 94%, and 100%, respectively. CONCLUSION: Multi-detector row helical CT enteroclysis allows depiction of small-bowel diseases in patients suspected of having small-bowel conditions. 相似文献
