Beyond the Common: A Case Report on Right Paraduodenal Hernia

Paraduodenal hernias, particularly those on the right side, are rare but clinically significant occurrences characterized by the abnormal protrusion of abdominal contents through mesenteric defects adjacent to the duodenum. These hernias result from embryologic malformations and can lead to complications such as intermittent abdominal pain, nausea, and, in severe cases, bowel obstruction. This case describes a 48-year-old male who presented with a 24-hour history of colicky abdominal pain in the right upper quadrant, associated with nausea. Further investigation, including a computed tomography scan, revealed a right paraduodenal hernia with herniation of small bowel loops through a mesenteric defect. Timely surgical intervention via laparoscopic exploration confirmed the diagnosis and facilitated the reduction of herniated bowel, followed by meticulous repair of the mesenteric defect using nonabsorbable sutures. The patient's recovery was uneventful, with a return to normal bowel function, and postoperative follow-up showed the resolution of symptoms. This case underscores the clinical complexity and management challenges associated with right paraduodenal hernias. Surgical intervention, guided by laparoscopic exploration, emerged as an effective and minimally invasive approach. The successful reduction of herniated small bowel loops and meticulous closure of the mesenteric defect contributed to a favorable postoperative course, highlighting the importance of timely intervention to prevent complications.
