Value of laparoscopy and laparoscopic ultrasonography in determining resectability of colorectal hepatic metastases.

Background: The aim was to assess the value of laparoscopy and laparoscopic ultrasonography (LUS) in selecting patients for resection of colorectal hepatic metastases.

Methods: Sixty patients with potentially resectable colorectal hepatic metastases after helical computer tomography (CT) and scheduled to undergo laparoscopy and LUS were studied retrospectively. Primary outcome measurement was the number of cases in which laparoscopy and LUS resulted in a change of therapeutic approach.

Prospective comparative study of spiral computer tomography and magnetic resonance imaging for detection of hepatocellular carcinoma.

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).

Fine needle aspiration cytology of thyroid nodules: how accurate is it and what are the causes of discrepant cases?

Fine-needle aspiration cytology (FNAC) is widely accepted as the most accurate, sensitive, specific and cost-effective diagnostic procedure in the assessment of thyroid nodules and helps to select people preoperatively for surgery. The purpose of this study was to evaluate the results of thyroid FNAC in our institution and to determine the reasons for discrepancies between the cytological and histological diagnosis. We evaluated the cytological and histological results of 254 FNACs obtained from 231 patients who underwent subsequent thyroid surgery.
