Emergency laparoscopic repair of left paraduodenal hernia in a young man: a case report.

Background: Paraduodenal hernia (PDH) isa rare congenital intra-abdominal hernia, especially in young people. It is often caused by abnormal intestinal rotation. The clinical manifestations lack specificity and are frequently misdiagnosed or overlooked. This article reports the diagnosis and treatment of a young male with left paraduodenal hernia (PDH) and explores its diagnosis and minimally invasive treatment strategy. Case data: A 26-year-old male patient was admitted to the hospital due to "abdominal pain for 7 h". Physical examination showed tenderness in the left upper abdomen. CT revealed clustered bowel loops adjacent to the ascending duodenum, and PDH was considered. Emergency laparoscopic exploration confirmed that part of the jejunum herniated into the Landzert recess. Hernia ring release, intestinal tube reduction and hernia ring suture repair were performed, and the patient recovered well after the operation. Discussion: Preoperative diagnosis of PDHrelies on imaging, especially enhanced CT, while laparoscopic surgery enables precise reduction of herniated contents and closure of the defect, reducing postoperative complications. This case suggests that even young patients with unexplained intestinal obstruction should be alert to the possibility of PDH, and early surgical intervention can improve prognosis. Conclusion: Although rare, PDH carries significant risk of fatality. Clinicians need to raise their awareness. Combined with early diagnosis by imaging, laparoscopic surgery is a safe and effective treatment method.
