Intestinal Obstruction Categories.
Canadian Medical Guide Definition Afferent Loop Syndrome - A complication of gastrojejunostomy (BILLROTH II PROCEDURE), a reconstructive GASTROENTEROSTOMY. It is caused by acute (complete) or chronic (intermittent) obstruction of the afferent jejunal loop due to HERNIA, intussusception, kinking, VOLVULUS, etc. It is characterized by PAIN and VOMITING of BILE-stained fluid.
Canadian Medical Guide Definition Fecal Impaction - Formation of a firm impassable mass of stool in the RECTUM or distal COLON.
Canadian Medical Guide Definition Ileus - A condition caused by the lack of intestinal PERISTALSIS or INTESTINAL MOTILITY without any mechanical obstruction. This interference of the flow of INTESTINAL CONTENTS often leads to INTESTINAL OBSTRUCTION. Ileus may be classified into postoperative, inflammatory, metabolic, neurogenic, and drug-induced.
Canadian Medical Guide Definition Intestinal Volvulus - A twisting in the intestine (INTESTINES) that can cause INTESTINAL OBSTRUCTION.
Canadian Medical Guide Definition Intussusception - A form of intestinal obstruction caused by the PROLAPSE of a part of the intestine into the adjoining intestinal lumen. There are four types: colic, involving segments of the LARGE INTESTINE; enteric, involving only the SMALL INTESTINE; ileocecal, in which the ILEOCECAL VALVE prolapses into the CECUM, drawing the ILEUM along with it; and ileocolic, in which the ileum prolapses through the ileocecal valve into the COLON.
