Abstract
Paraduodenal hernia (PDH), also known as mesocolic hernia, is a rare internal hernia resulting from a congenital anomaly caused by improper retroperitoneal fixation of the mesentery due to abnormal midgut rotation. Although uncommon, internal hernias can cause acute intestinal obstruction and pose a life-threatening risk if not promptly diagnosed and managed. This case report presents a 25-year-old male with a two-month history of progressively worsening abdominal pain, exacerbated by food intake and accompanied by vomiting. Imaging via contrast-enhanced CT revealed a left PDH, with clustering of jejunal loops and displacement of mesenteric vessels. The patient underwent successful laparoscopic surgical repair, including hernia sac reduction and defect closure. Timely identification and surgical intervention were critical in preventing complications such as intestinal perforation and peritonitis. This case underscores the clinical importance of considering PDH in patients with recurrent abdominal symptoms and highlights the benefits of early diagnosis and minimally invasive surgical management.
