Overview

The mainstay treatment of bowel obstruction is surgical and non-operative management. The role of medical therapy is supportive and is limited by palliative pain management in cancer patients, fluid and electrolyte replenishment, decreasing abdominal distension, peritumoral edema, intraluminal secretions, peristaltic movements, and control of nausea and vomiting.

The role of medical therapy is supportive and is limited by control of vomiting and nausea, fluid and electrolyte replenishment, palliative pain management in cancer patients, decreasing abdominal distension, peritumoral edema, intraluminal secretions, and peristaltic movements.
