Small bowel obstructions that are caused by adhesions require surgery in almost every case. In cases of partial bowel obstruction or complete bowel obstruction without severe symptoms, surgery may be delayed for 12 to 24 hours to allow a dehydrated patient to receive fluids intravenously (into a vein) prior to the operation. In this case, a small suction tube that extends through the nose and into the stomach can be used to prevent additional bloating and to relieve pain and nausea. When adhesions cause intestinal strangulation, immediate abdominal surgery is required to remove the adhesions so that blood flow to the bowel can be restored.
