目的 探讨超声肠腔充盈造影（UIFC）对大肠形态及走行变异的应用价值。 方法 受检查者于检查前禁食8 h，检查前6 h左右口服聚乙二醇电解质散Ⅰ进行清洁灌肠；将胃肠声学造影剂从肛门灌入肠道，行肠腔充盈超声造影；分析UIFC对大肠形态及走行变异应用价值。 结果 超声肠腔充盈造影检查266例，发现大肠形态、走行变异18例，共11种类型，分别为乙状结肠游走6例，横结肠低位3例，脾曲弯曲畸形、短升结肠、降结肠平行变异、无结肠肝曲伴短升结肠、巨大升结肠、结肠肝曲畸形、无回盲瓣、降结肠扭曲、无结肠脾曲伴短降结肠各1例。 结论 超声肠腔充盈造影可为大肠形态、走形变异的筛查提供了有效可行的手段。

Objective To investigate the application value of ultrasonic intestinal filling contrast（UIFC）method in morphology and walking variation of large intestine. Methods The examines were checked before fasting for 8 hours, 6 hours before the examination of oral polyethylene glycol electrolyte powder(Ⅰ) for cleaning enema, and gastrointestinal contrast agent into the intestinal tract from the anus after irrigation, and then for intestinal filling contrast ultrasonography. Finally, the application value of UIFC method in morphology and walking variation of large intestine were analyzed. Results Two handred and sixty-six cases of UIFC examination were found that there were changes in walking and morphology of the large intestine in 18 cases, a total of 11 types: 6 cases of sigmoid colon walk, 3 cases of transverse short low, and splenic flexure bending deformity，short ascending colon, descending colon parallel variation,no colon hepatic flexure with short ascending colon, huge ascending colon, hepatic flexure of the colon malformation,no ileocecal valve, descending colon twist,no colon splenic flexure with short descending colon 1 case each. Conclusion The ultrasonic intestinal filling contrast provides a feasible and effective method for screening variation of the morphology and walking variation of large intestine and has important value in clinical application and variation of anatomical structure.
