【摘要】：目的:探討低張水灌腸低劑量MDCT在大腸疾病體檢篩查中的臨床應(yīng)用價(jià)值。方法:156例體檢者分別進(jìn)行大腸低劑量MDCT掃描(A組)、鋇劑灌腸(B組)和內(nèi)鏡檢查(C組)。以病理或臨床診斷作為參照,比較3種檢查方法檢出大腸病變的敏感性和特異性。以操作難度、配合難度、舒適感、檢查時(shí)間和可能性傷害共5個(gè)問(wèn)題設(shè)計(jì)調(diào)查表來(lái)評(píng)估患者對(duì)3種檢查方法的可耐受性,并進(jìn)行統(tǒng)計(jì)學(xué)分析。結(jié)果:156例中經(jīng)病理和臨床確診的大腸病變63例,其中腫瘤17例、炎性病變45例、腸套疊1例。A、B、C三組檢出病變的敏感度和特異度分別為52.4%和95.7%、6.3%和92.5%,85.7%和97.8%,三組間敏感度的差異有統(tǒng)計(jì)學(xué)意義(P0.05),特異度的差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)。患者對(duì)3種檢查方法的耐受性低的例數(shù)分別為34例、22例和122例,患者對(duì)內(nèi)鏡檢查的可耐受性顯著低于MDCT和鋇劑灌腸(P0.05)。結(jié)論:低張水灌腸低劑量MDCT技術(shù)能較好地顯示大腸的解剖結(jié)構(gòu)、可行性高,可為內(nèi)鏡和鋇劑灌腸檢查提供補(bǔ)充信息,可推薦作為大腸病變體檢篩查的常規(guī)檢查方法。
[Abstract]:Objective: to evaluate the clinical value of low-dose MDCT in screening for colorectal diseases. Methods one hundred and fifty-six healthy subjects were examined with low-dose MDCT in group A, group B with barium enema and group C with endoscopy. The sensitivity and specificity of three methods for detecting colorectal lesions were compared with pathological or clinical diagnosis. A questionnaire was designed to evaluate the patient's tolerance to the three test methods according to five questions: difficulty of operation, difficulty of coordination, comfort, time of examination and possible injury, and the statistical analysis was carried out. Results among 156 cases, 63 cases were diagnosed by pathology and clinic, including 17 cases of tumor and 45 cases of inflammatory lesion. The sensitivity and specificity of the three groups of intussusception were 52.4% and 95.7% and 92.5%, 85.7% and 97.8%, respectively. There was significant difference in sensitivity between the three groups (P 0.05), but there was no significant difference in specificity between the three groups (P 0.05). The number of patients with low tolerance to the three methods were 34 cases (22 cases) and 122 cases (122 cases) respectively. The patients' tolerance to endoscopic examination was significantly lower than that of MDCT and barium enema (P0.05). Conclusion: the low-dose MDCT technique of low-tension-water enema can display the anatomical structure of large intestine well and has high feasibility. It can provide supplementary information for endoscopy and barium enema examination, and can be recommended as a routine examination method for the screening of colorectal diseases.
