Ileum and colon, the bowel segments used most commonly in urinary diversion, possess similar transport properties. When exposed to urine in which the concentration of potassium and hydrogen is typically higher and the concentration of sodium is lower than intestinal contents, these segments secrete sodium and bicarbonate and absorb hydrogen, chloride, and ammonium.
What is Colon and Ileum Removal: Overview, Benefits, and Expected Results
The colon, also known as the large intestine, is connected to the small intestine by the ileum. When certain gastrointestinal conditions cause irreversible damage to both the colon and the ileum, it sometimes becomes necessary to remove them both through a surgical procedure.
The Anatomical Position of the Ileum in Health and Disease
The jejunum and ileum are attached to the posterior abdominal wall by an extensive fold of peritoneum, the mesentery, which allows the freest motion, so that each coil can accommodate itself to changes in form and position.
6 Autophagy and defective microbial killing
Despite the tremendous progress in our understanding of the pathogenesis of inflammatory bowel diseases (IBD) the reason why CD is primarily located in the distal part of the ileum remains unexplained. However, in the last few years a constellation of findings mainly genetic in nature have given a great contribution to the genotype–phenotype correlations. Taken together these arguments seem to provide a rational hypothesis to explain the enigma of terminal ileitis. The main arguments in favour of the distal ileal localization of CD will be discussed down here.
Endometriosis of the Terminal Ileum: A Diagnostic Dilemma
Along its six metre length the jejuno-ileum changes gradually: it becomes narrower, thinner walled, and less vascular. The loops of jejuno-ileum are attached to the posterior abdominal wall by this peritoneal sheet, the mesentery.
Duodenal heterotopia in the distal ileum
Duodenal heterotopia is an extremely uncommon form of heterotopia. Despite an exhaustive search of available Literature, we could come across only a few reports of duodenal heterotopia . We report a case of a young 8 year old girl who presented with peritonitis and was found to have duodenal heterotopia in the resected part of the ileum.

Jejunal atresia is a rare genetic condition that can affect newborns. It involves missing all or part of the mesentery, which connects the small intestine to the abdominal wall. This causes the jejunum to twist around an artery that supplies the colon with blood, leading to a blockage of the intestines.
By the way, doctor: Does a colonoscopy reach the ileum?
When comparing the CT features of patients with neoplastic ileal thickening and those of patients with nonneoplastic ileal wall thickening, we found that the group with neoplastic ileal involvement had larger tumors, longer affected segments, more severe involvement of the ileocecal valve, and a higher incidence of lymphadenopathy, vascular engorgement, small-intestinal obstruction, and pericolonic infiltration than the group with nonneoplastic ileal thickening. However, statistical analysis could not be obtained because of the limited number of patients.
