Internal hernia is herniation of a viscus, usually in the small bowel, through a normal or abnormal aperture within the peritoneal cavity. Its incidence has been reported to be one to two per cent. Internal hernias are classified based on location, and the hernial orifice can be either congenital or acquired. Paraduodenal hernias are the most common type (53 per cent). Paraduodenal hernia is of...

a 47 years old lady presented with repeated intermittent, colicky, left upper, and periumblical abdominal pain associated with nausea and vomiting since two years prior to admission. each episode of the pain spontaneously subsided after bilious vomiting. the patient had no history of surgery, abdominal trauma or intra-abdominal infection, weight loss or previous history for small bowel obstruct...

Introduction. Internal hernias are often misdiagnosed because of their rarity, with subsequent significant morbidity. Case Presentation. A 61-year-old Japanese man with no history of surgery was referred for intermittent abdominal pain. CT suggested the presence of a transmesocolic internal hernia. The patient underwent a surgical procedure and was diagnosed with transmesocolic internal hernia....

background: mesocolic hernias are extremely rare. their exact incidence is still unknown. the clinical features are nonspecific and range from bilious vomiting and chronic abdominal pain exacerbated by meals, to asymptomatic presentations incidentally discovered during surgery. preoperative diagnosis still is difficult in spite of imaging techniques currently available. case report: in this stu...

Internal hernia is a rare cause of intestinal obstruction and most cases of internal hernia are left paraduodenal hernia. It typically involves the fossa of Landzert just lateral to the fourth portion of the duodenum. Patients with left paraduodenal hernia do not have specific clinical manifestations and preoperative radiological diagnosis is difficult. Mortality increases significantly with de...

a 41-year old mentally retarded patient presented acutely with a 3 day history of vomiting and absolute constipation.  intestinal obstruction was diagnosed following an abdominal x ray. at laparotomy, a left paraduodenal hernia was present, without incarceration of small bowel. the herniated loops were reduced and the hernia orifice closed. the anatomy, treatment and importance of considering t...

Internal hernia represents only a small fraction of the patients with intestinal obstruction, however 50% of paraduodenal hernia present as an acute intestinal obstruction. The case is a 28-year old man with presentation of complete bowel obstruction. Diagnosis confirmed through physical examination and abdominal radiography. Laparatomy was performed during which total herniation of small intes...

Paraduodenal hernia is the most common form of congenital internal hernia and constitutes a protrusion of bowel into the retroperitoneal space through peritoneal defects near the third and fourth portion of the duodenum. The lifetime risk of obstruction and bowel strangulation is around 50% with a mortality of 20% and higher. Despite the rarity of the disease, it poses a serious surgical proble...

Internal intestinal hernia has been defined as bulging of the intestines through a normal or an abnormal peritoneal or mesenteric opening. Paraduodenal hernias comprise 30%-53% of all internal intestinal herniations and account for 0.2%-0.9% of all bowel obstructions. In this paper, we aimed to present a male patient of 42 years of age who developed intestinal obstruction due to left paraduoden...
