The Effect of Carbon Dioxide Insufflation Applied at Different Pressures and Periods on Thrombotic Factors.

The aim of this experimantal study which is applied on rats, is to determine the differences on the clotting factors over the application of low and high intraabdominal pressure (IAP) values in different periods of time in carbon dioxide (CO2) pneumoperitoneum. Thirty rats were randomized into five groups (n = 6): a control group (Group K) and 1 h and 6 mm Hg IAP (Group A), 2 h and 6 mm Hg IAP (Group B), 1 h and 12 mm Hg IAP (Group C) and 2 h and 12 mm Hg IAP were created with CO2 pneumoperitoneum (Group D). At the end of the experiment, plasma samples taken from subjects and fibrinogen, FII (prothrombin), FV, FVII, FVIII, FIX, FX, FXI, FXII, von willebrand's factor (vWF), ristocetin cofactor, protein C, protein S, antithrombin III (AT III) levels are studied. There were statistically significant differences in the mean levels of FII, FV, FVII, FVIII, FIX, FX, FXI, FXII, and protein S between the groups. A hypercoagulable state occurred with the following: increase in the coagulation parameters compared to the control group; increase in FVII in the group only Group C; decrease in AT III in all groups compared to the control group; decrease in protein C in the group only XII Group D compared to control group; decrease in protein S in all groups except group D compared to control group. CO2 insufflation predisposes to thromboembolic events both by inducing coagulation factors and by suppressing the fibrinolytic system contrary to the controversies in the literature

A very feasible alternative in patients with feeding difficulties from gastrostomy: Jejunal tube advanced through the gastrostomy.

Our aim is to share our experiences regarding patients who cannot be fed effectively through the gastrostomy tube, but were inserted feeding jejunostomy through the gastrostomy orifice using scopic fluoroscopic techniques utilised by the interventional radiology

Our experience in two cases of type IV laryngotracheoesophageal cleft (LTEC) with a diagnosis of antenatal esophageal atresia.

Laryngotracheoesophageal clefts (LTECs) are rare congenital defects that are often accompanied by additional anomalies. The major issues in the treatment of these patients are intraoperative exposure insufficiency, technical difficulty of the operation, and anesthesia problems originating from the respiratory tract. Problems originating from mechanical ventilation and respiratory tract, eating disorders and relapse of fistula are among the problems encountered following surgery. Most of the time, concomitant additional anomalies also worsen the clinical picture. It was our aim with these case reports to report our experience in two cases with Type IV LTEC ranging from the inoperable type IV LTEC due to additional anomalies mounted up to severe respiratory distress to the carina that we operated on with a single stage anterior cervicothoracic approach on its fifth day on life

The effect of alfuzosin on renal resistive index, urinary electrolytes and 2 microglobulin levels and TGF-1 levels of kidney tissue in rats with unilateral ureteropelvic junction obstruction

Background: In this study, it was aimed to determine the effects of alfuzosin on experimentally generated unilateral partial ureteropelvic junction obstruction (UPO) in rats.Materials and methods: Thirty Long-Evans rats were randomly allocated into five groups. In control group (C), nothing was performed; in group Sham (S) only laparotomy was done; in Alfuzosin group (A) only alfuzosin was administered for two weeks (10mg/kg/day p.o.) without any surgery; in UPO group, unilateral UP junction obstruction was produced; and in the Group UPT (ureteropelvic obstruction+treatment), alfuzosin was administered for two weeks (10mg/kg/day p.o.) in addition to UPO production. Renal pelvic anteroposterior diameters were determined with ultrasonography (USG) and renal arterial resistivity indexes by color Doppler USG. Urine was collected both at the beginning and at the end of the experiment for 24h in all the groups and at the end of the experiment, blood samples were obtained. Blood and urine electrolytes and TGF-1, urine density, urine (2) microglobulin levels were determined. Renal tissue samples harvested from all of the rats were histopathologically evaluated. Results were determined using one-way ANOVA t-test; p<0.05 was accepted as significant.Results: Urine density in the UPT group was lower with respect to UPO group and blood electrolytes were preserved as close to normal (p<0.05). In the UPT group, urine TGF-1 and blood TGF-1, blood (2) microglobulin levels and histopathologic damage scores were lower compared to the UPO group (p<0.05).Conclusion: It is shown in this experimental unilateral partial UPO model that alfuzosin treatment prevents obstructive renal damage
