Effects of intestinal ischemia-reperfusion on major conduit arteries.

Intestinal ischemia-reperfusion (I-R) is a common and serious clinical condition associated with simultaneous remote organ dysfunction. The purpose of this study was to investigate the effects of intestinal I-R on the vasomotor functions of major conduit arteries. Anesthetized rabbits were randomly assigned to one of three groups: sham-operated controls (Group I), and one-hour intestinal ischemia with two-hour reperfusion (Group II) or four-hour reperfusion (Group III).

Hemodynamic changes in the early phase of artificially created arteriovenous fistula: color Doppler ultrasonographic findings.

The objective of this study was to evaluate hemodynamic variables in arteriovenous fistulas by color Doppler ultrasonography. This study involved 28 patients with chronic renal failure who were sent to surgery clinic for creation of an arteriovenous fistula of the Brescia-Cimino type. Patients were evaluated preoperatively and on the first and seventh days postoperatively by a color Doppler ultrasound machine with a 7.

Effect of haemodynamic variables on surgically created arteriovenous fistula flow.

Background: The immediate success and flow rate of a newly constructed arteriovenous fistula is dependent on several haemodynamic factors affecting the inflow and outflow of the fistula.

Methods: In this study we evaluated the effect of preoperative arterial blood pressure, arterial inflow, subclavian venous flow, and operative venous outflow resistance on the immediate success, with special reference to the quantity of the fistula flow in 32 patients undergoing internal arteriovenous fistula operations. Flow measurements were done by utilizing colour flow duplex imaging and measurement of venous resistance of the fistula vein was accomplished indirectly by a newly developed simple system.

Effect of lactulose on bacterial translocation.

Objective: To find out if lactulose can prevent the bacterial translocation that is induced by obstructive jaundice in rats.

Design: Laboratory experiment.

Setting: Teaching hospital, Turkey.

Surgical treatment of advanced alveolar hydatid disease of the liver: a report of five cases.

We report herein the cases of five patients with alveolar hydatid disease (AHD) of the liver who were diagnosed and underwent surgery at the Department of Surgery of Ankara University between 1989 and 1994. In all five patients, the final diagnosis was established by frozen section of the lesion during laparotomy. Lesions of AHD were found only in the liver.

Treatment of acute sigmoid volvulus.

Thirty-eight patients were treated for acute sigmoid volvulus in 9 years. Non operative decompression treatment was performed in 7 patients, and 31 patients underwent exploratory laparatomy (25 for suspected bowel necrosis and 6 for unsuccessful non operative treatment). Sigmoid resection and reanastomosis was performed in 5 of the 12 cases with gangrenous bowel and 10 of the 19 with viable bowel.
