Intestinal obstruction. Note the tense wall indicative of gas under pressure and volvulus.
Bowel obstruction is most often caused by intestinal adhesions, which frequently form after abdominal surgeries, or by chronic infections such as diverticulitis, hepatitis, and inflammatory bowel disease. The condition is difficult to diagnose properly, as the symptoms may resemble those of other bowel disorders.
Bowel infarction. Note the grey discoloration.
Patients who have undergone extensive resection of the small bowel may develop malabsorption, indicating the need for dietary supplements.
Volvulus is a rare but life-threatening cause of bowel infarction which requires immediate medical attention. Central abdominal pain which is resistant to narcotic analgesia may be an indication of bowel infarction.
