摘要

回盲瓣是胃肠道的一部分,它将解剖结构和功能都不同的两个肠段分隔开来。功能障碍或手术切除瓣膜通常会导致小肠细菌过度生长综合征。现有文献缺乏对回盲瓣的更广泛讨论和超声展示。本研究旨在将回盲瓣的经腹超声检查与结肠镜检查和计算机断层扫描结肠成像数据进行对比,介绍我们的经验。在手稿的这一部分,我们讨论了右髂窝中构成回盲部肠段的解剖结构。回盲部瓣膜有两种形态:唇状瓣膜和乳头状瓣膜,是其中心部分。如计算机断层扫描结肠成像所示,第一种类型更常见,占 76%,第二种类型占 21%,而回盲瓣脂肪瘤则占 3%。死后研究显示,瓣膜脂肪瘤病的发病率明显更高,每 5 例病例中就有 4 例。我们的观察结果与这些研究结果一致。回盲部瓣膜脂肪瘤病在超声检查中表现为高回声、圆形病变,彩色多普勒检查无明显血管。这种图像应特别与脂肪瘤这种相对常见的大肠病变相鉴别。本文介绍了两种超声扫描的准备方法(即仅在空腹或清洗肠道后),并确定了使用经腹超声对回盲瓣进行成像的最佳方法。回盲部检查结束后,应记得评估右髂窝的淋巴结。

The ileocecal valve in transabdominal ultrasound Part 1: Sonographic anatomy and technique
The ileocecal valve is a part of the gastrointestinal tract that separates two intestinal segments differing in both anatomy and function. Dysfunction or surgical removal of the valve usually results in the develop- ment of small intestinal bacterial overgrowth syndrome. The available literature lacks a broader discus- sion and ultrasound presentation of the ileocecal valve. The aim of this study is to present our experience in transabdominal ultrasound of the ileocecal valve in comparison with colonoscopic and computed tomography colonography data. In this part of the manuscript, we discuss the anatomical structures in the right iliac fossa that make up the ileocecal segment of the intestine. The ileocecal valve, which comes in two morphological forms: labial and papillary, is its central part. As shown in computed tomography colonography, the first type is more common, accounting for 76%, the second type accounts for 21%, whereas ileocecal valve lipomatosis is found in 3% of cases. Post-mortem studies have shown a signifi- cantly higher incidence of valve lipomatosis, which was found in up to 4 out of 5 cases. Our observations correspond with these findings. Ileocecal valve lipomatosis presents on ultrasound as a hyperechoic, well-circumscribed lesion, with no evident vascularity on color Doppler. This image should be differ- entiated especially from a lipoma, a relatively common large intestinal pathology. The paper presents two methods of preparation for an ultrasound scan (i.e. only on an empty stomach or after cleansing the intestine) and determines the optimal imaging methods for the ileocecal valve using transabdominal ultrasound. At the end of the ileocecal examination, it should be remembered to assess the lymph nodes in the right iliac fossa.
