Diagnostic Considerations

Suspect bowel perforation in patients with persistent unexplained tachycardia, fever, or abdominal pain. In addition, malignancy, such as colorectal carcinoma, should be considered for all patients who present with large-bowel obstruction (LBO).

Other conditions that should be considered when evaluating a patient with large-bowel obstruction include constipation, cecal or sigmoid volvulus, intussusception, intestinal perforation, Ogilvie syndrome, mesenteric and mesenteric artery ischemia. As noted earlier, incarcerated hernias are a frequently missed cause of bowel obstruction, particularly left-sided inguinal hernias in which colon obstruction occurs with the sigmoid colon incarcerated in the hernia.[11]
