title: Laparoscopic repair of a right paraduodenal hernia.
abstract: BACKGROUND
  Laparoscopic repair of a right paraduodenal hernia has never been described in the literature. A 24-year-old woman was admitted after 2 weeks of intermittent abdominal pain associated with nausea and vomiting. Physical examination was normal. Laboratory studies and upper endoscopy were normal. Computed tomography revealed that the small bowel was on the right side of the abdomen and the colon on the left, suspicious for malrotation. Subsequent upper gastrointestinal series with small bowel follow-through revealed the ligament of Treitz on the right with the small bowel encased within a probable hernia sac. A presumptive diagnosis of a right paraduodenal hernia was made.
  
  
  RESULTS
  Initial access was obtained with a 10-mm infraumbilical port followed by placement of 5-mm ports in the right and left upper and lower quadrants. The duodenum was identified and the small bowel was found encased within a hernia sac, which was opened widely from the duodenum to the pelvis. The hernia sac was opened laterally to avoid injury to the superior mesenteric vessels. The small bowel was then released from the sac into the peritoneal cavity. The entire bowel was inspected and no other abnormalities were noted. The patient had resolution of her abdominal pain and her postoperative course was uncomplicated. She was discharged home on postoperative day 3 and has since done exceptionally well.
  
  
  CONCLUSIONS
  Paraduodenal hernia, a rare cause of small bowel obstruction, can present a diagnostic challenge. However, when the diagnosis is made preoperatively, a laparoscopic repair is a feasible and practical option.
