Liver resection using a four-prong radiofrequency transection device.

Multiple techniques are available for division of hepatic parenchyma. This is the largest United States report examining the use of the Habib 4X tissue coagulator (AngioDynamics, Queensbury, NY). The objective was to collect standard parameters associated with successful, benchmarked liver surgery outcomes using this new device, and in particular, examine the risk of margin failure.

Determinants of failure in superficial femoral artery angioplasty.

Although results of iliac artery balloon angioplasty have been shown to be good, there are much less data regarding initial success and durability of superficial femoral artery (SFA) dilation. The authors retrospectively reviewed the results of 22 patients treated for 27 SFA lesions between 1981 and 1986. Mean age was 64.

Carotid artery disease in patients with head and neck carcinoma.

Irradiation has been shown experimentally to cause accelerated development of atherosclerosis in exposed large arteries. However, occurrence of such an entity in carotid arteries of patients after treatment for head and neck carcinoma is unknown. Therefore, we reviewed 179 patient charts who had undergone head and neck operations with or without irradiation between 1979-1987.

The role of endogenous prostaglandins in the regulation of gastric secretion in rhesus monkeys.

Prostaglandins (PG) are known to alter a variety of gastrointestinal functions, but the physiological role of endogenous PG remains unclear. This experiment was designed to evaluate changes in gastric secretion following both acute and chronic inhibition of PG synthesis with indomethacin (5 mg/kg s.c.

Alterations in gastric mucus secretion in rhesus monkeys after exposure to ionizing radiation.

The aim of the present study was to evaluate the effect of gamma-irradiation on soluble gastric mucus. Six conscious chair-adapted rhesus monkeys were studied once before and twice after exposure to ionizing irradiation (800 rads). Using a marker (99mTc-DTPA) dilution technique, acidic glycoprotein (AG), neutral glycoprotein (NG), ion, and fluid output were determined during a basal period and after the administration of an 80-ml water load.
