title: [Fixation anomaly of the duodenum. Apropos of 4 cases].
abstract: "Z"--shaped duodenum and "roller - coaster" duodenum are synonyms for malfixation of the duodenum. This rare malformation has been described recently. We report 4 cases (ages 3 months-9 years) with: --intermittent abdominal pain; --bilious vomiting; --failure to thrive. Radiologic examination of the upper gastrointestinal tract revealed a malformation of the distal duodenum (D2-D3) which presented a "Z" or "M" form and under fluoroscopy, this portion was very mobile, causing intermittent obstruction when it became kinked. All attempts of medical management have failed. At surgery, all the bands were cut, giving the duodenum a normal shape. The symptoms disappeared after surgery. Follow-up between 4 months and 3 years showed the patients were completely asymptomatic.
