Preventable deaths from small bowel obstruction result from misdiagnosis, inappropriate delay in operation, inadequate preoperative preparation, and a poorly performed operative procedure. A systematic approach to each of the factors includes repeat physical examination, x-rays and CBC four hours after initial study in questionable cases, a pre-planned therapeutic interventions timetable, adequate intravascular volume and electrolyte levels, and a carefully designed operation which includes as little bowel manipulation and entrance as possible.
