title: Randomised trial of jejunoileal bypass versus medical treatment in morbid obesity. The Danish Obesity Project.
abstract: In a randomised clinical trial to assess the value of intestinal bypass in the treatment of gross obesity 130 patients who underwent end-to-side jejunoileostomy (with either a 1/3 or a 3/1 ratio between jejunum and ileum left in continuity) were compared with 66 non-surgically treated patients. All patients in the study had gross, long-standing, treatment-resistant obesity with resultant somatic, psychic, or social problems; none were alcoholic or had liver disease or other conditions which made them poor surgical risks. Most subjects were observed for more than 3 years. Median weight loss within 24 months was 42.9 kg in the bypass group, compared with 5.9 kg in the control group. No deaths occurred among those who underwent surgery. Patients who underwent intestinal bypass also had a better improvement in quality of life and a higher degree of patient satisfaction. Complications of the operation were, however, common and occasionally severe.
