Causes
Causes by Localization
Small Bowel obstruction
- Adhesions from previous abdominal surgery
- Carcinoid rare, preferred location: ileum
- Crohn's disease causing adhesions or inflammatory strictures
- Foreign bodies (e.g. gallstones in gallstone ileus, swallowed objects)
- Hernias containing bowel
- Intestinal atresia
- Intussusception in children
- Ischaemic strictures
- Neoplasms, benign or malignant
- Volvulus
-
Upright abdominal X-ray demonstrating a small bowel obstruction. Note multiple air fluid levels.
Large Bowel obstruction
Causes of large bowel obstruction include:
- Neoplasms
- Hernias
- Inflammatory bowel disease
- Colonic volvulus (sigmoid, caecal, transverse colon)
- Faecal impaction
- Colon atresia
- Benign strictures (Diverticular Disease)
-
Upright abdominal X-ray of a patient with a large bowel obstruction showing multiple air fluid levels and dilated loops of bowel.
Causes by Organ System
- Miscellaneous syndromes
- Paralytic Ileus
- Pseudo-obstruction or Ogilvie's syndrome
- Chromosomal abnormalities
- Autosomal dominant conditions
- Neurofibromatosis type 1
- Malignant neoplastic conditions
- Trauma, mechanical and physical conditions
- Infectious disorders
- Ascariasis
- Intra-abdominal sepsis
- Pneumonia or other systemic illness
