title: Rare small bowel obstruction: Right paraduodenal hernia. Case report.
abstract: BACKGROUND
  Paraduodenal hernia (paramesocolic hernia), a rare congenital anomaly due to a midgut malrotation during fetal development, is recognized as the most frequent internal hernias. Two variants have been described: left and right, the latter less common than the first one.
  
  
  METHODS
  We report a right paraduodenal hernia case in a 86 years old female patient who developed an acute bowel obstruction syndrome. Final diagnosis was achieved by imaging techniques as abdomen X-ray and CT and confirmed only after surgical operation.
  
  
  CONCLUSIONS
  Surgical approach was via median laparotomy, consisting in hernia reduction, replacement and stitching of the bowel in its anatomical orientation, and fixing of the posterior wall defect. At 15 months follow-up from surgical procedure the patient is asymptomatic.
  
  
  CONCLUSIONS
  Paraduodenal hernia is a rare pathology but its involvement in bowel obstruction syndrome should be always taken into account during diagnostic process.
