Left paraduodenal hernia presenting as recurrent small bowel obstruction

Internal hemiation of the small bowel is a relatively rare cause of intestinal obstruction. Left paraduodenal hernia resulting from abnormal rotation of the midgut during embryonic development is the most common form of congenital internal hernia. We report our experience in the diagnosis and management of a young male with left paraduodenal hernia presenting as recurrent intestinal obstruction. Correct preoperative diagnosis of left paraduodenal hernia had been difficult due to non-specific clinical presentations, but the advent of modern imaging technology makes early and correct diagnosis possible, Due to the risk of obstruction and strangulation, surgical treatment is indicated; however, timely intervention increases the likelihood of a favorable outcome.

Intestinal Obstruction and Bowel Ischemia due to a Rare Left Paraduodenal Hernia: Case Report

Bowel obstruction is one of the most common problems found in outpatient departments (OPDs) and emergency rooms. The challenge for surgeons is to be suspicious and recognizing rare disease that could cause bowel obstruction, such as paraduodenal hernia, without delaying the management as the risk of complications increase. This case study presents a patient with bowel obstruction secondary to a paraduodenal hernia.

Left paraduodenal hernia in an adult complicated by ascending colon cancer: A case report

Paraduodenal hernia is the most common internal hernia. The clinical symptoms of paraduodenal hernia may be intermittent and nonspecific. Therefore, it is difficult to diagnose preoperatively. Abdominal computed tomography （CT） scan currently plays an important role in the evaluation and management of paraduodenal hernia before surgical operation. We report one unique case of preoperatively diagnosed left paraduodenal hernia complicated by advanced ascending colon cancer and reviews of Japanese literature.

Laparoscopic correction of hydronephrosis caused by left paraduodenal hernia in a child with cryptorchism:A case report

BACKGROUND Paraduodenal hernia(PDH)is a mesenteric-parietal hernia with retroperitoneal and retrocolic herniation of the small bowel into a sac,which is formed by a peritoneal fold located near the fourth portion of the duodenum.The present case revealed that PDH was a possible reason for hydronephrosis,and that the carful laparoscopic exploration surgery was necessary to find infrequent causes of hydronephrosis to avoid invalid Anderson–Hynes pyeloplasty surgery and its injury.CASE SUMMARY An 8-year-old boy presented to the pediatric department with a chief complaint of cryptorchidism.Afterwards,laparoscopy confirmed hydronephrosis secondary to left PDH with cryptorchid.Then,he received laparoscopic surgery,fixed operation for left PDH,release of the ureteropelvic junction obstruction,and treatment for hydronephrosis.It is necessary to perform secondary surgery for cryptorchidism and long-term follow-up.CONCLUSION The case revealed an extremely rare cause of hydronephrosis in children,suggesting a potential correlation between PDH and hydronephrosis.

Stranched Internal Hernia Revealed by Occlusion of the Large Libra: A Propos of a Case

The left para-duodenal internal hernia, whose origin is generally embryological, is a rare etiology of intestinal obstruction found mainly in young adults. We report here the case of acute intestinal obstruction by left para-duodenal internal hernia in a 36-year-old young man. It was a patient who consulted urgently for occlusive syndrome with cessation of materials and gases. Abdominal percussion noted abdominal tympanism and pre-hepatic dullness was preserved. The flow and icicle signs were negative. Palpation did not objectify hepatosplenomegaly and did not find any organomegaly either. On the other hand, she found an epigastric defense. The abdominal X-ray without preparation showed water levels that were wider than high, hail-like. We performed a median above and below umbilical laparotomy and intraoperatively, it was an internal hernia with incarceration of small loops in a voluminous left paraduodenal sac of 12 cm. They were not necrotic and quickly recolored after extrication. We resected the hernial sac and closed the hernial orifice with separate stitches with absorbable suture 0. The postoperative course was simple. The patient was discharged from the hospital on the 4th postoperative day. After 18 months of hindsight, he is doing well.

Incarceration of Meckel's diverticulum in a left paraduodenal Treitz' hernia

Meckel's diverticula incarcerated in a hernia were first described anecdotally by Littré, a French surgeon, in 1700. Meckel, a German anatomist and surgeon, explained the pathophysiology of this disease 100 years later. In addition, a congenital paraduodenal mesocolic hernia, known as a Treitz hernia, is a rare cause of small bowel obstruction. These hernias are caused by an abnormal rotation of the primitive midgut, resulting in a right or left paraduodenal hernia. We treated a patient presenting with pain and diagnosed extraluminal air in the abdomen after a computed tomography examination. We performed a laparotomy and found a combination of these two seldomly occurring congenital diseases, incarceration and perforation of Meckel's diverticulum in a left paraduodenal hernia. We performed a thorough review of the literature, and this report is the first to describe a patient with a combination of these two rare conditions. We considered the case regarding the variety of terminology as well as the treatment options of these conditions.

Right paraduodenal hernia:report of two cases and review of literature

Paraduodenal hernia(PDH),a rare congenital anomaly,is a type of internal hernia which occurs due to a defect in the reduction and rotation of the midgut.On anatomical and embryological basis,PDH can be broadly divided into right-and Left PDH.Right PDH is rarer than its counterpart.We present two cases of Right PDH.The patientsy presented with a history of recurrent intestinal obstruction since childhood,which was managed conservatively,without a definitive diagnosis.Once they presented to us,a detailed clinical history and a barium meal follow-through clinched the diagnosis of PDH.Intra-operative findings correlated well with the clinical diagnosis.The jejunal loops had herniated through the fossa of Waldeyer.Reduction of hernia contents and excision of the hernia sac was carried out.Post-operatively,the patients are healthy and symptom-free at 4 and 3 years follow-up,respectively.The rarity of this condition and the need for early diagnosis,to prevent the high risk of bowel obstruction and strangulation,makes PDH one of the difficult challenges for the clinicians.
