Ultimately, the shunts were converted to jejunoileostomies in which the upper portion of the jejunum was anastomosed to the lower portion of the ileum .
The latter might be a confusion with ileum , the third portion of the small intestine.
The patient was treated with surgical resection of the distal jejunum, proximal ileum , and the 3 nodules of the liver.
The midgut eventually develops into distal duodenum, jejunum, ileum , caecum, appendix, ascending colon, and proximal two thirds of the transverse colon.
Approximately 90% of the fluid contained in the ileum (ie, distal portion of the small intestine) is absorbed in the colon.
Hydrochloric acid and pepsin secreted by the gastric mucosa cause the adjacent ileal mucosa of the intestine to erode and ulcerate since the normal protective mucosa is missing.
A detailed review of the patient's medical records confirmed a right hemicolectomy for an ileal carcinoid with lymph node and omental metastases that had been performed elsewhere 10 years earlier.
Biopsies of the polyp and random colonic and ileal mucosa were performed.
Sections from the ileum showed the polyps to be composed of multiple closely aggregated lymphoid follicles in the lamina propria of the ileal mucosa.
Two tumors were spindle cell leiomyosarcomas (gastric and ileac ); 1 was an epithelioid leiomyosarcoma of the colon; and 1 was an epithelioid GIST of the colon.
