肠扭转的CT诊断

CT diagnosis of intestinal volvulus

目的探讨肠扭转的各种CT征象及其临床诊断价值。方法分析11例经手术证实肠扭转的CT表现,其中平扫8例,平扫加增强扫描3例。结果11例中"漩涡征"6例,"靶征"4例,肠腔扩张积气积液9例,腹水征6例,肠壁积气征1例,"花瓣状"1例,大跨度肠曲1例。结论"漩涡征"是诊断肠扭转的特异性征象。"靶征"、肠壁积气征,是诊断肠缺血的可靠征象。

Objective To discuss the manifestations of intestinal volvulus and evaluate the role of CT in diagnosing the disease. Methods CT findings in 11 cases of intestinal volvulus proved by operation were retrospectively analyzed.8 cases were scanned with plain CT and 3 cases were scaned with plain CT following with enhanced CT. Results ＂whirl＂sign was seen in 6 cases and ＂target＂sign in 4 cases, dilatation of bowl loops fulled with gas and lipuid in 9 cases, seroperitoneum appeared in 6 cases, emphysema of the intestinum wall detected in 1 case. Conclusion ＂whirl＂sign is the main evidence which can be relied on to diagnose intestinal volvulus. ＂target＂sign and emphysema of bowel wall are the reliable signs which meaning ischemia of intestinum due to intestinal volvulus.
