Small bowel obstruction
Alerts and Notices
Synopsis
Small bowel obstruction is characterized by abdominal pain, failure to move bowels or pass flatus, nausea, and often emesis, depending on the location of the obstruction. Patients who have had prior abdominal surgery, hernias, inflammatory intestinal processes, malignancies in or around the small intestine, foreign body ingestion, or prior radiation exposure are at particularly high risk for developing small bowel obstructions.
The greatest concern from a small bowel obstruction is the risk of increased dilation leading to necrosis and perforation of the bowel.
