Aim. This study aimed at assessing Doppler ultrasonographic findings of gut wall vessels and thickness in active and quiescent ulcerative colitis. Methods. Fifty patients with ulcerative colitis were studied using transabdominal grayscale and Doppler sonography of sigmoid, distal and middle parts of descending colon in different stages of the disease. Thickness of colon wall in the most involved site, number of color signals in each box, resistive index (RI), and pulsatility index (PI) were evaluated. Results. The median thickness of the colon wall in the most involved sites was 4.3 mm in acute phase and 4.4 mm in the inactive phase (P = 0.47). The median number of the color signals in the active phase at the most involved site, distal part of descending colon and sigmoid was higher than that of the color signals in the inactive phase (P = 0.0001). In the most involved site, the PI and RI were undetectable in the inactive phase. The median PI was 1.4 in the mild phase, 1.3 in the moderate phase, and 1.1 in the severe phase (P = 0.002). Conclusion. In contrast to the colon wall thickness, increased intramural blood flow reflected the clinical severity in ulcerative colitis patients.
目的。本研究旨在评估活动期和静止期溃疡性结肠炎肠壁血管的多普勒超声检查结果及肠壁厚度。方法。对50例溃疡性结肠炎患者在疾病不同阶段进行经腹乙状结肠、降结肠远端和中段的灰阶及多普勒超声检查。评估最受累部位的结肠壁厚度、每个区域的彩色血流信号数量、阻力指数（RI）和搏动指数（PI）。结果。急性期最受累部位结肠壁的中位厚度为4.3毫米，静止期为4.4毫米（P = 0.47）。活动期在最受累部位、降结肠远端和乙状结肠的彩色血流信号中位数量高于静止期（P = 0.0001）。在最受累部位，静止期无法检测到PI和RI。轻度期的中位PI为1.4，中度期为1.3，重度期为1.1（P = 0.002）。结论。与结肠壁厚度不同，壁内血流增加反映了溃疡性结肠炎患者的临床严重程度。
