背景:白斑疝是相对罕见的疝类型。它们表现为位于脐和剑突软骨之间的白线中的小突起。通常,疝内容物包括腹膜前脂肪,网膜,和胃肠道。然而,很少报道涉及肝圆韧带的白线疝病例,到目前为止。
方法:一名80岁女性患者出现上腹痛和1周的上中线肿块病史。腹部计算机断层扫描显示脂肪组织从腹壁突出,与肝圆韧带相邻,提示阿尔巴线疝.手术期间,疝囊内容物被发现是一个肿块,被切除了。使用网片修复了20mm的白线疝缺损。组织病理学发现,肿块包括成熟的脂肪细胞增殖和宽的纤维间隔,被诊断为肝圆韧带纤维脂肪瘤。
结论:我们报告了全球首例涉及肝圆韧带纤维脂肪瘤的白线疝,并描述了临床特征,诊断,和外科手术并进行文献综述。
BACKGROUND: Linea alba hernias are relatively rare types of hernias. They manifest as small protrusions situated in the linea alba between the umbilicus and xiphoid cartilage. Usually, hernia contents comprise the pre-peritoneal fat, omentum, and gastrointestinal tract. However, very few cases of linea alba hernias involving the hepatic round ligament have been reported, to date.
METHODS: An 80-year-old woman presented with upper abdominal pain and a 1-week history of a mass in the upper midline. Abdominal computed tomography revealed adipose tissue protruding from the abdominal wall contiguous with the hepatic round ligament, suggesting a linea alba hernia. During surgery, the hernial sac content was found to be a mass, which was resected. A linea alba hernia defect measuring 20 mm was repaired using a mesh. Histopathological findings revealed that the mass included mature adipocyte proliferation with broad fibrous septa, which was diagnosed as
fibrolipoma of the hepatic round ligament.
CONCLUSIONS: We report the first case of a linea alba hernia involving
fibrolipoma of the hepatic round ligament worldwide and describe the clinical features, diagnosis, and surgical procedure with a literature review.
