AB Intestinal  obstruction  results  from  mechanical  blockage  or  the  loss  of  normal  peristalsis.  Adynamic  or  paralytic  ileus  is  more  common  and  usually  self-limiting.  Common  causes  of  mechanical  small  bowel  obstruction  (SBO)  are  adhesions  due  to  previous  surgery,  incarcerated  hernias,  or  inflammatory  diseases.  Other  causes  to  consider  are  inflammatory  bowel  diseases,  congenital  anomalies,  and  foreign  bodies.  The  most  frequent  causes  of  large  bowel  obstructions  are  cancer,  diverticulitis  with  stricture,  sigmoid  volvulus,  and  fecal  impaction.  Consider  intussusception  in  children.  Sigmoid  volvulus  is  more  common  in  the  elderly  taking  anticholinergic  medications  while  cecal  volvulus  is  more  common  in  gravid  patients.  Intestinal  pseudoobstruction  (Ogilvie  syndrome)  may  mimic  large  bowel  obstruction.  The  elderly  and  bedridden  and  patients  taking  anticholinergic  medications  or  tricyclic  antidepressants  are  at  increased  risk  for  pseudoobstruction.
