Small bowel<unk>  Upright abdominal X-ray demonstrating a small bowel<unk> . Note multiple air fluid levels. Causes of small bowel<unk>  include: * Adhesions from previous abdominal surgery (most common cause) * Barbed sutures * Pseudoobstruction * Hernias 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) *<unk>  atresia After abdominal surgery, the incidence of small bowel<unk>  from any cause is 9%. In those where the cause of the<unk>  was clear, adhesions are the single most common cause (more than half). Large bowel<unk>  Upright abdominal X-ray of a person with a large bowel<unk>  showing multiple air fluid levels and dilated loops of bowel Causes of large bowel<unk>  include: * Neoplasms / cancer * Diverticulitis / Diverticulosis * Hernias * Inflammatory bowel disease * Colonic volvulus (sigmoid, caecal, transverse colon) * Adhesions * Constipation * Fecal impaction * Fecaloma * Colon atresia *<unk>  pseudoobstruction * Endometriosis * Narcotic induced (especially with the large doses given to cancer or palliative care patients) Outlet<unk>  Outlet<unk>  is a sub-type of large bowel<unk>  and refers to conditions affecting the anorectal region that obstruct defecation, specifically conditions of the pelvic floor and anal sphincters. Outlet<unk>  can be classified into four groups. * Functional outlet<unk>  * 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<unk>  * Internal intussusception * Enterocele * Dissipation of force vector * rectocele * Descending perineum * Rectal prolapse * Impaired rectal sensitivity * Megarectum * Rectal hyposensitivity
