Overview
Small bowel obstruction causes include post-adbominal surgery adhesions, foreign bodies and intussusception. Large bowel obstruction causes include neoplasms, hernias and constipation. Miscellaneous causes include, paralytic ileus and Down syndrome. Causes by organ system include, ovarian cancer, bowel strangulation and ascariasis. Mechanical obstruction can be caused by pregnancy, Hirschsprung's disease and Crohn's disease. Non-mechanical obstruction may be caused by ovarian torsion, pancreatitis and lead poisoning. Drug induced bowel obstruction can occur by intake of lanthanum carbonate, methscopolamine bromide, and teduglutide.
Causes
Causes by Localization
Small bowel obstruction
Causes of small bowel obstruction include:[1]
- Adhesions
- From previous abdominal surgery
- Carcinoid tumor
- Rare, preferred location is the ileum
- Crohn's disease
- Causes adhesions or inflammatory strictures
- Foreign bodies
- Including gallstones in gallstone ileus and swallowed objects
- Hernia
- Especially hernias containing bowel
- Intestinal atresia
- Intussusception
- Specifically in children
- Ischaemic strictures
- Neoplasms
- Volvulus
Large bowel obstruction
Causes of large bowel obstruction include:[1]
- Neoplasms
- Hernias
- Inflammatory bowel disease
- Volvulus
- Specifically sigmoid, caecal, and colonic volvulus
- Faecal impaction
- Colon atresia
- Benign strictures
- Such as those that occur with diverticular disease
Outlet obstruction
- Functional outlet obstruction
- Internal anal sphincter spasm
