In the present case, the resection specimen definitely showed islands of metaplastic bone superficial to the muscularis propria, thus excluding sacral invasion. 此例中,切除的标本中很明确的显示出固有肌层浅表的岛状化生骨,因此可以排除骶骨侵犯。
Endoscopic submucosal dissection with ligation for treatment of small gastric submucosal tumors originated from the muscularis propria layer 内镜黏膜下剥离术治疗早期胃肠道肿瘤并发症及其处理应用结扎技术进行内镜黏膜下剥离术治疗胃固有肌层小肿瘤
Epithelium of intestinal villus is simple columnar epithelium, muscularis mucosa is not obvious, and there are central lacteals in lamina propria but there are not duodenal glands. 小肠绒毛上皮是单层柱状上皮,粘膜肌不明显,有中央乳糜管,无十二指肠腺。
33 benign stromal tumors from muscularis propria, 18 malignent stromal tumors, 2 lipoma and 2 etopic pancrease, 1 carcinoid were resected surgically. 33例源于固有肌层的良性间质瘤、18例恶性间质瘤、2例脂肪瘤、2例异位胰腺及1例类癌经手术切除。
The incidence of tumors originating from the muscularis propria layer in the upper gastrointestinal tract is increasing year by year and the age of onset has been younger. 上消化道固有肌层肿瘤的发病率逐年升高,且伴有年轻化的趋势,由于此病早期症状不明显,很难自我发现。
Background: Gastrointestinal tract wall can be divided into mucosa, submucosa, muscularis propria and serosa in total of four layers, while upper gastrointestinal tract owns a thick muscularis propria. 背景消化道管壁由内向外依次分为粘膜层、粘膜下层、固有肌层及浆膜层共四部分,其中上消化道的固有肌层较厚。
