The role of intraoperative ultrasound for the assessment of the focal liver lesions in patients with colorectal cancer.

Objective: To evaluate the concordance between intraoperative ultrasound (IOUS) and abdominal ultrasound (US) for the characterization of focal liver lesions in patients with colorectal cancer, and to evaluate the way in which IOUS influences the initially established hepatic surgical protocol based on abdominal US only.

Method: In this prospective study 73 patients with colorectal cancer and focal liver lesions found during IOUS were included. Abdominal US and IOUS findings were compared.

A case of portal cavernoma--associated essential thrombocythemia.

Portal cavernoma is a rare complication of portal vein thrombosis and may be a component of the myeloproliferative hematologic disorders. In the present case report, although the symptoms induced by portal hypertension and portal biliopathy had a concordant evolution with the portal cavernoma, the peripheral thrombocytosis and the medullar expression of essential thrombocythemia became relevant at 18 months.
