Differentiation of benign and malignant bowel lesions by transabdominal ultrasound using grey-scale and Doppler parameters.

Background And Study Aims: The aim of this study was to assess the ability of transabdominal ultrasonographic morphologic features and Doppler flow parameters in differentiating benign from malignant bowel lesions.

Patients And Methods: Sixty patients with sonographically detected gastrointestinal lesions and 30 control subjects were prospectively enrolled. Bowel wall thickness; length of the affected segment; the wall layering pattern; the resistive index (RI); pulsatility index (PI); flow volume (FV) of the intramural vessels, the superior mesenteric artery (SMA), and the portal vein (PV) were recorded.

Role of peritoneal ultrasonography and ultrasound-guided fine needle aspiration cytology/biopsy of extravisceral masses in the diagnosis of ascites of undetermined origin.

Background And Study Aims: Ascites may be of undetermined origin despite comprehensive study. This study aimed to assess the accuracy and safety of conventional and interventional high-frequency peritoneal ultrasound in the diagnosis of patients with ascites of unclear origin.

Patients And Methods: A total of 62 patients were prospectively enrolled; they underwent conventional (3.

T cells are depleted in HCV-Induced hepatocellular carcinoma patients: possible role of apoptosis and p53.

Egypt has possibly the highest Hepatitis C Virus (HCV) prevalence worldwide. A high proportion of HCV infections become chronic and lead to liver cirrhosis and hepatocellular carcinoma (HCC). The cellular and molecular mechanisms behind HCV infection complication are not completely understood although apoptosis has been implicated in this process.
