A Case Report of Left Paraduodenal Hernia in a young boy

Internal hernia is a relatively uncommon condition and is a rare type of intestinal obstruction. Paraduodenal hernia (PDH) is the most frequent type of congenital hernia, especially on the left side. Although acute intestinal obstruction due to internal hernias is rare, it can be fatal if it is not identified and treated right away. The clinical diagnosis of paraduodenal hernia is difficult due to its rarity and variable symptoms. Here, we present the case of a 14-year-old boy who had been experiencing intermittent abdominal pain for a week duration. The pain had been worse during the previous two days, and the boy also experienced nausea and repeated vomiting episodes. He was otherwise healthy and had no history of previous abdominal operations. A left paraduodenal hernia was diagnosed based on the findings of a computed tomography scan, which showed a dilated small bowel loop occupying the left hypochondrial region anterior to the pararenal region. Due to the complicated nature of the disease, the patient had an exploratory laparotomy, during which herniated jejunal loops were reduced and hernial sac wide opened to prevent a recurrence. The patient tolerated the procedure, and recovery was uneventful. This case sheds light on the importance of considering the diagnosis of left paraduodenal hernia in patients with abdominal pain, particularly among those who have not undergone abdominal surgery previously. Early detection and treatment can prevent life-threatening complications such as intestinal perforation and peritonitis.
