Abstract:
Introduction: Large bowel obstruction (LBO) is a less common cause of bowel obstruction, but
it has a broad range of differentials. The most common etiology in the United States is colorectal
adenocarcinoma. Patient presentation includes diffuse abdominal pain, constipation, abdominal
distension, and nausea. Abdominal X-rays can quickly assess bowel dilation, but CT scan is the
gold standard to determine location and severity of blockage. Treatment can range from IV fluid
to emergent colectomy.
