The ileocecal valve is typically located on the last fold before entry into the cecum and can be located from the direction of curvature of the appendiceal orifice, in what is known as the bow and arrow sign. [4] Intubation of the ileocecal valve is typically performed in colonoscopy to evaluate the distal, or lowest, part of the ileum.
Small bowel or colon cancer may require surgical resection. [7] Small bowel cancer often presents late in the course due to non-specific symptoms and has poor survival rates. Risk factors for small bowel cancer include genetically inherited polyposis syndromes, age over sixty years, and history of Crohn's or Celiac disease.
Common causes of small bowel obstruction include post-operative adhesions, hernias, intussusception, and intraabdominal tumors. Common causes of colonic obstruction include primary colon cancer, volvulus and post-operative adhesions. When the ileocecal valve is competent, colonic obstruction may manifest as gaseous distention of the colon, but ...
It is caused by an incomplete obstruction of the small intestine and especially of the ileocecal valve, e.g. in Crohn's disease, or in rare cases of cancer of the small intestine. It is named after the German surgeon, Franz König (1832–1910), and should not be confused with König's disease, also named after him.
A lower gastrointestinal bleed is defined as bleeding originating distal to the ileocecal valve, which includes the colon, rectum, and anus. [2] LGIB was previously defined as any bleed that occurs distal to the ligament of Treitz, which included the aforementioned parts of the intestine and also included the last 1/4 of the duodenum and the entire area of the jejunum and ileum.

The connection between the end of the small intestine (ileum) and the start (as viewed from the perspective of food being processed) of the colon (cecum) is now clearly understood, and is called the ileocecal orifice. The connection between the end of the cecum and the beginning of the ascending colon is called the cecocolic orifice.

Identifying the ileocecal valve in a colonoscopy is important, as it indicates that the entire colon has been visualized. The identifiable landmarks in the cecum are the appendiceal orifice —which is a curvilinear indent indicating the location of the appendix from the lumen of the bowel—and the ileocecal valve, which appears as a puckering ...
