【摘要】：目的研究雙能CT結(jié)腸成像部分自動(dòng)個(gè)體化充注空氣擴(kuò)張結(jié)直腸受檢者依從性及結(jié)直腸充氣擴(kuò)張效果。方法選擇46例沒(méi)有影響胃腸道運(yùn)動(dòng)功能病史的健康成年志愿者,CT檢查前1d開(kāi)始5次口服4.0%泛影葡胺60mL標(biāo)記腸內(nèi)容物。利用充氣機(jī)部分自動(dòng)、個(gè)體化充注空氣擴(kuò)張結(jié)直腸,充氣體位先右側(cè)臥位,再緩慢改為仰臥位,速率開(kāi)始為1.5L/min,后期降低到0.5L/min,并根據(jù)偵察圖像結(jié)直腸充氣擴(kuò)張效果、志愿者自我感覺(jué)及腸腔壓力確定是否需要增補(bǔ)充氣及充氣量。仰臥位雙能CT掃描,獲得雙能融合圖像。統(tǒng)計(jì)分析志愿者的依從性,Kruskal-Wallis H檢驗(yàn)比較結(jié)直腸充氣擴(kuò)張效果。結(jié)果 46例志愿者均沒(méi)有腹痛、腹脹、惡心或嘔吐等,容易接受結(jié)直腸充氣擴(kuò)張,依從性1級(jí)。結(jié)直腸充氣擴(kuò)張1、2、3、4級(jí)效果分別占0%、2.1%、5.1%、92.8%。結(jié)直腸各段腸管充氣擴(kuò)張效果比較差異無(wú)統(tǒng)計(jì)學(xué)意義(χ~2=6.19,P=0.288)。6段腸管充氣擴(kuò)張差,乙狀結(jié)腸、直腸各占2段。14段腸管充氣擴(kuò)張欠佳,降結(jié)腸、乙狀結(jié)腸、直腸分別占4、4、3段。結(jié)論部分自動(dòng)個(gè)體化充注空氣擴(kuò)張結(jié)直腸受檢者依從性非常好,能夠良好地充氣擴(kuò)張結(jié)直腸各段腸管。
[Abstract]:Objective to study the compliance and inflatable dilatation effect of dual energy CT colon imaging patients with partial automatic air filling for colorectal dilatation. Methods 46 healthy adult volunteers who had no history of gastrointestinal motor function were enrolled in this study. The intestinal contents were labeled with 4. 0% meglumine diatrizoate (60mL) for 5 times from the first day before CT examination. The inflatable machine was used to partially automate the expansion of the colon and rectum by filling the air individually. The inflated body position was first in the right lateral position, then slowly changed to the supine position. The rate began at 1.5 L / min, and later decreased to 0.5 L / min. According to the effect of colonorectal inflatable dilation, volunteers' self-perception and intestinal pressure were used to determine the need for additional inflatable and inflatable volume. Supine position dual-energy CT scan to obtain dual-energy fusion image. The compliance of volunteers was statistically analyzed. Kruskal-Wallis H test was used to compare the effect of colorectal inflatable dilatation. Results 46 volunteers had no abdominal pain, abdominal distension, nausea or vomiting. The effect of inflatable dilatation of the colon and rectum was 0.2.1and 5.1and 92.8%, respectively. There was no significant difference in the effect of inflatable dilatation between colon and rectum (蠂 ~ 26.19 ~ 0.288). 6 segments of intestine were not inflated, 2 segments were sigmoid colon, 2 segments were rectum, 14 segments were not well inflated, descending colon, sigmoid colon, and sigmoid colon. The rectum accounted for 4 pieces and 3 segments respectively. Conclusion the compliance of partial individualized air filling for colorectal dilatation is very good, and it can inflate and dilate the colon and rectum well.
