ObjectiveTo test the hypothesis that laparoscopic staging improves outcome in patients with peripancreatic carcinoma compared to standard radiology staging. Summary Background DataDiagnostic laparoscopy of peripancreatic malignancies has been reported to improve assessment of tumor stage and to prevent unnecessary exploratory laparotomies in 10% to 76% of patients. MethodsLaparoscopy and laparoscopic ultrasound were performed in 297 consecutive patients with peripancreatic carcinoma scheduled for surgery after radiologic staging. Patients with pathology-proven unresectable tumors were randomly allocated to either surgical or endoscopic palliation. All others underwent laparotomy.

BACKGROUND AND PURPOSE: Our aim was to determine the diagnostic accuracy of multisection CT angiography combined with matched mask bone elimination (CTA-MMBE) for detection of intracranial aneurysms compared with digital subtraction angiography (DSA) and 3D rotational angiography (3DRA).

In this study laparoscopy was not an effective staging technique for oesophageal carcinoma. The inclusion of laparoscopic ultrasonography was of little benefit. A problem that was encountered was biopsy under laparoscopic guidance. In carcinoma of the gastric cardia, laparoscopy was more effective; adding laparoscopic ultrasonography doubled the number of patients seen to have metastatic disease.

Background: Hepatocellular carcinoma (HCC) is often detected at a relatively late stage when tumour size prohibits curative surgery. Screening to detect HCC at an early stage is performed for patients at risk. Aim: The aim of this study was to compare prospectively the diagnostic accuracy and classification for management of the two state of the art secondline imaging techniques: triphasic spiral computer tomography (CT) and super paramagnetic iron oxide (SPIO) enhanced magnetic resonance imaging (MRI). Patients: Sixty one patients were evaluated between January 1996 and January 1998. Patients underwent CT and MRI within a mean interval of 6.75 days. Methods: CT and MRI were evaluated blindly for the presence and number of lesions, characterisation of these lesions, and classification for management. For comparison of the data on characterisation, the CT and MRI findings were compared with histopathological studies of the surgical specimens and/or follow up imaging. Data of patients not lost to follow up were available to January 2001. Results: SPIO enhanced MRI detected more lesions and overall smaller lesions than triphasic spiral CT (number of lesions 189 v 124; median diameter 1.0 v 1.8 cm; Spearman rank's correlation coefficient 0.63, p<0.001). There was no significant difference in accuracy between CT and MRI for lesion characterisation. The agreement in classification for management was very good (weighted kappa 0.91, 95% CI 0.83-0.99). Conclusion: SPIO enhanced MRI detects more and smaller lesions, but both techniques are comparable in terms of classification for management. SPIO enhanced MRI may be preferred as there is no exposure to ionising radiation.
