Anesthetic management of a patient with undiagnosed paraganglioma -a case report-.

Retroperitoneal paragangliomas are uncommon neuroendocrine tumors which are derived from extra-adrenal paraganglioma with various clinical signs and symptoms. Although most extra-adrenal paragangliomas are histologically benign, some tumors can synthesize and secrete excess catecholamine from the tumor. Excessive production of catecholamine causes numerous cardiovascular manifestations such as severe hypertension, cardiomyopathy, cardiac arrhythmias, and even multiorgan failure.

Rhabdomyolysis after laparoscopic radical nephrectomy -A case report-.

Rhabdomyolysis is a rare but potentially lethal clinical syndrome that results from acute muscle fiber necrosis with leakage of muscle constituents into blood. This devastating disease could be due to muscle compression caused by urologic positioning for a lengthy nephrectomy. In this regard, laparoscopic renal surgery may be a risk for the development of rhabdomyolysis.

Comparison of the neuroendocrine and inflammatory responses after laparoscopic and abdominal hysterectomy.

Background: Laparoscopic surgery is associated with a more favorable clinical outcome than that of conventional open surgery. This might be related to the magnitude of the tissue trauma. The aim of the present study was to examine the differences of the neuroendocrine and inflammatory responses between the two surgical techniques.
