Özet
Objective: To assess changes in mesenteric blood flow caused by smoking after meals in healthy young adults. Subjects and Methods: A total of 50 participants, 22 smokers and 28 non-smokers, were enrolled in the study. Volunteers were divided into three groups: group A, non-smokers (n=28), group B, smokers and smoked postprandially (n=18), group C, smokers but were not allowed to smoke postprandially (n=16). Twelve people participated in both groups B and C. Doppler sonography was performed when the participants were hungry (baseline) and was repeated 30, 60, and 90 minutes after a standard meal. SMA (superior mesenteric artery) and PV (portal vein) flow parameters were measured. Results: The peak systolic velocity (PSV) of the SMA were significantly higher both baseline and postprandial in group B (p=0.048). The mean vessel diameters and flow volume group averages did not differ based on smoking (F=1.542, p=0.222; F=2.082, p=0.134). Variations in SMA diameter averages in the three groups were different (F=6.406, p<0.001). The mean maximum velocity of the PV and the peak systolic velocity of the SMA were the lowest in group C (p=0.048 and p=0.026). Conclusion: Both smoking and breaking the habit of postprandial smoking diminish mesenteric flow.
