| | Intestinal Obstruction |
 | | Obstruction of the small bowel: Small-bowel (jejunoileal) obstruction is commonly caused by incarceration in hernias or by adhesions and is less commonly caused by tumors (primary or metastatic), obturation by foreign bodies, a Meckel's diverticulum, or Crohn's disease. |
 | | Obstruction of the duodenum: Duodenal obstruction is usually caused by cancer, primarily in the duodenum or head of the pancreas. |
 | | Severe intestinal distention is self-perpetuating and progressive, intensifying the peristaltic and secretory derangements and increasing the risks of dehydration, ischemia, necrosis, perforation, peritonitis, and death. |
