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...

Paraduodenal hernia is a rare etiology of intestinal obstruction. Its preoperative diagnosis can only be made by a well-performed upper gastrointestinal series. We report a case of a 19 years old man with abdominal pains and recurrent Koenig's syndromes. The upper gastrointestinal series and CT scan showed a right paraduodenal hernia. we reviewed the anatomy. physiopathology, symptoms and radio...

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...

ABSTRACT Introduction: Encasing of small bowel in an anomalous accessory membrane results in peritoneal encapsulation and is a very rare cause of intestinal obstruction. It is believed to be caused by malrotation of the bowel during the 12th week of gestation and this causes the formation of an accessory sac from the peritoneum, covering the umbilicus. Left paraduodenal hernia is the most commo...

OBJECTIVE We report a case of primary hypertrophic pyloric stenosis combined with a paraduodenal hernia in a 35-year-old woman. CLINICAL PRESENTATION AND INTERVENTION The patient presented with signs of obstructive ileus. CT of the abdomen revealed a marked dilatation of the stomach and the proximal jejunum as well as a circumferential thickening of the antral-pyloric region with characterist...

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 an uncommon cause of acute abdominal pain; however, it is the commonest of internal herniation. Computer tomography of the abdomen is diagnostic. Although it is a rare cause of intestinal obstruction, it is estimated that more than half of paraduodenal hernias develop symptoms. We present a case of left paraduodenal hernia that presented with acute abdominal pain and a le...

Paraduodenal hernia, a rare congenital anomaly which arises from an error of rotation of the midgut, is the most common type of intraabdominal hernia. There are two variants, right and left paraduodenal hernia, the right being less common. We report the case of a 41-year-old patient with a right paraduodenal hernia with a 6-month history of intermittent episodes of intestinal obstruction. Diagn...

Paraduodenal hernia is a rare congenital malformation. Management consists of reduction of the herniated intestine and repair of the defect. A 74-year-old woman presented to the Emergency Department with persistent right upper quadrant pain that began 3 hours ago. Physical examination revealed tenderness at right upper quadrant of abdomen. Computed tomography revealed multiple gallstones with g...

INTRODUCTION Cases of right paraduodenal hernia and superior mesenteric artery syndrome have been reported separately, but their occurrence in combination has not been reported. CASE PRESENTATION A 46-year-old Japanese man who had never undergone laparotomy was admitted to our hospital due to an acute abdomen. An enhanced multidetector-row computed tomography scan of our patient showed a clus...
