What Causes Ileum Inflammation?
The ileum is a small intestine that connects the jejunum and cecum. It has a curved shape and is located in the mammalian small intestine. The ileum is characterized by the mesentery connected to one edge and the ileum into the cecum on the other edge.

- The ileum is a small intestine that connects the jejunum and cecum. It has a curved shape and is located in the mammalian small intestine. The ileum is characterized by the mesentery connected to one edge and the ileum into the cecum on the other edge.
Ileum Overview
- The ileum is the name of a human organ. Corresponds to the anatomy of the upper ileum and colon. "Lingshu · Gastroenterology": "The ileum acts as the left umbilicus, and the perilobular leaves accumulate, and the recirculation ring reverses the sixteen curves, four inches in size, less than half an inch in diameter, and two feet in length." In addition, about 2 % Of adults have cystic protrusions of 2-5 cm in length on the mesangial border of the ileum from the end of the ileum, which protrudes outward from the intestinal wall. This is called Meckel's diverticulum, which is an incomplete yolk sac tube during the embryonic period. Formed by disappearing. Meckel's diverticulum is susceptible to inflammation or ulcer perforation. It is located close to the appendix and has symptoms similar to appendicitis. The ileum takes up about 3/5 of the ileum and is mainly located in the umbilical and right iliac regions. Both the jejunum and the jejunum belong to the internal organs of the peritoneum and are suspended from the posterior wall by the mesentery. Its characteristics are light red, thin tube wall diameter, small and low annular folds on the mucosal surface. In addition to isolated lymphoid follicles, collective lymphoid follicles can also be seen. There are more vascular arches in the mesangium and richer fat.
Ileum vascular arch anatomy
- This article observes the anatomical basis of whether the ileum has blood supply and ischemia after the selected superior mesenteric arteries and veins under the right colonic artery are isolated. Verify the location of the arteriovenous vein (under the colonic arteries) on the mesenteric artery used in the previous surgery, and observe whether the severed intestine can effectively loosen the small intestine and extend it to the required length. Use this method to release the vascular arch restraint to ensure that the anastomosis tension will not be high during and after the ileal pouch and ileal pouch-anal anastomosis. Through the anatomy observation of 45 corpses, combined with the experience of previous surgery, it was further demonstrated that the arteries and veins of the "xuan" lateral mesentery can be broken under the right colon artery, which can "extend" the small intestine by 50 to 60 cm. A small intestine with a sufficient length for small intestine pouching and ileal pouch anal anastomosis. According to the anatomy, the ileum mesentery "There are 9 to 11 communication branches between each row of vascular arches. The entire ileal mesenteric vascular arch is connected by the communication branches to form a vascular network. Like a spider web, blood flows in the ileal mesentery" The ileal blood supply is adequate. The arteries and veins above the mesentery should be severed under the right colon artery. Because there were two to five columns of vascular arches able to provide blood after the superior mesenteric artery and vein were severed at this location, the anatomic results of 45 cases confirmed this, and the aforementioned "surgery" also confirmed. In terms of ileal blood supply protection, there is no difference between male and female HJ. In the field of general surgery, a new surgical method J, such as separation of superior mesenteric arteries and veins, total rectal muscle sheath ileal pouch-anal canal anastomosis, has appeared. There should be enough clinical cases and anatomical observations to confirm and improve. The anatomical observation of the ileum vascular arch in 45 cases in this study further confirmed from the anatomy that the superior mesenteric arteriovenous vein was broken under the right colon artery, and the length of the small intestine was extended by 50-60 cm, avoiding high tension anastomosis. No ischemia after ileum. This anatomy further validated the feasibility of the surgical method of "severing the superior mesenteric arteries and veins, total rectal muscle sheath, and ileal pouch-anal anastomosis" under the right colon artery.
Ileum jejunum length
- The average length of men was 436.0 ± 80.9cm (275.0 ~ 600.0), and the average length of women was 375.0 ± 49.2cm (275.0-430.0). After statistical test, the sex difference was significant (P <0.05). There were 35 males and females with an average length of 413.0 ± 74.9cm. According to reports by Yan Weixin and others, formalin-fixed corpses shortened the intestinal tract by an average of 28.2 ± 2.0%. It is estimated that the length of the jejunum in this group before fixation was about It is 530.0cm. The ratio of the length to the length of the jejunum was 1: 2.6. With regard to the length of the jejunum, textbooks and documentation are not uniform. Hirscb et al. (1956) determined that the average small intestine length of an adult living body is only 282.0 cm. After the mesangium was cut out from fresh corpses without preservation, the length of the small intestine was 600.0 to 800.0 cm. It is generally believed that the length of the bowel of an unfixed corpse is much longer than that of a living body due to the disappearance of muscle tension. After the anti-corrosion fixation, the length is shortened. It is also related to the measurement method.
