Small bowel obstruction Upright abdominal X-ray demonstrating a small bowel obstruction. Note multiple air fluid levels. Causes of small bowel obstruction include: * Adhesions from previous abdominal surgery (most common cause) * Barbed sutures * Pseudoobstruction *<unk> s containing bowel * Crohn's disease causing adhesions or inflammatory strictures * Neoplasms, benign or malignant * Intussusception * Volvulus * Superior mesenteric artery syndrome, a compression of the duodenum by the superior mesenteric artery and the abdominal aorta * Ischemic strictures * Foreign bodies (e.g. gallstones in gallstone ileus, swallowed objects such as expandable water toys) * Intestinal atresia After abdominal surgery, the incidence of small bowel obstruction from any cause is 9%. In those where the cause of the obstruction was clear, adhesions are the single most common cause (more than half). Large bowel obstruction Upright abdominal X-ray of a person with a large bowel obstruction showing multiple air fluid levels and dilated loops of bowel Causes of large bowel obstruction include: * Neoplasms / cancer * Diverticulitis / Diverticulosis *<unk> s * Inflammatory bowel disease * Colonic volvulus (sigmoid, caecal, transverse colon) * Adhesions * Constipation * Fecal impaction * Fecaloma * Colon atresia * Intestinal pseudoobstruction * Endometriosis * Narcotic induced (especially with the large doses given to cancer or palliative care patients) Outlet obstruction Outlet obstruction is a sub-type of large bowel obstruction and refers to conditions affecting the anorectal region that obstruct defecation, specifically conditions of the pelvic floor and anal sphincters. Outlet obstruction can be classified into four groups. * Functional outlet obstruction * Inefficient inhibition of the internal anal sphincter * Short-segment Hirschsprung's disease * Chagas disease * Hereditary internal sphincter myopathy * Inefficient relaxation of the striated pelvic floor muscles * Anismus (pelvic floor dyssynergia) * Multiple sclerosis * Spinal cord lesions * Mechanical outlet obstruction * Internal intussusception * Enterocele * Dissipation of force vector * rectocele * Descending perineum * Rectal prolapse * Impaired rectal sensitivity * Megarectum * Rectal hyposensitivity
