Left Paraduodenal Hernia: Case Report of Rare Cause of Recurrent Abdominal Pain

Internal hernia is a relatively uncommon condition and is a rare type of intestinal obstruction. Paraduodenal hernia is considered the most common type of internal hernias. The rare prevalence and the variable symptoms make the clinical diagnosis of paraduodenal hernia a diagnostic challenge. We present the case of a 26-year-old male patient presented with a seven-day history of generalized intermittent crampy abdominal pain accompanied by nausea and multiple episodes of vomiting. He was otherwise healthy and had no history of previous abdominal operations. Computed tomography scan of the abdomen demonstrated sac-like clustered small bowel loops noted in the left upper quadrant, in the anterior pararenal space, consistent with the diagnosis of left paraduodenal hernia. Laparoscopic surgery for the repair of the hernia was planned but it was converted to open surgery due to technical difficulties. The patient tolerated the procedure without complications, and he was asymptomatic in the follow-up visit. This case sheds light on the importance of considering the diagnosis of left paraduodenal hernia in patients with recurrent abdominal pain, particularly among those who have not undergone abdominal surgery previously.
