Para-duodenal hernia: a report of five cases and review of literature

BACKGROUND: Para-duodenal hernia (PDH) represents rare clinical entities based on few literatures. CASE PRESENTATION: We report five cases of Para-duodenal hernia, all occurring in male patients ranging from 34 to 75 years of age. The patients had varied manifestations presenting with abdominal pain with or without vomiting and nausea and with or without signs of intestinal obstruction. CT images showed cluster of dilated bowel segments with displaced mesenteric vessels at hernial orifice. Laparoscopic surgical approach was adopted, and the patients were discharged about a week later without further complications. CONCLUSION: We hope to raise awareness about the management of this rare clinical entity and the benefits of CT imaging and laparoscopic surgery as standard approaches.
