Gallstone ileus: rare and still controversial.

Background: Gallstone ileus is a rare disease and accounts for about 1-3% of mechanic ileus of the small bowel, but for 25% of all small bowel obstructions in patients older than 65 years. Concomitant cardiorespiratory diseases or diabetes are frequent in older patients and responsible for the high mortality rate. The aim of the present study was to evaluate and discuss different surgical approaches and to analyze the clinical outcome.

Overexpression of epithelial cell adhesion molecule antigen in gallbladder carcinoma is an independent marker for poor survival.

Purpose: Gallbladder carcinoma is an aggressive type of cancer that is difficult to cure by conventional procedures. There thus is a need to identify novel molecular markers for the assessment of prognosis and as potential therapeutic targets. This retrospective study was designed to investigate the prognostic significance of epithelial cell adhesion molecule (Ep-CAM) overexpression in human gallbladder carcinoma.
