Right paraduodenal hernia: a rare cause of intestinal obstruction

A 17 year old male was admitted emergently with acute small bowel obstruction. An urgent laparotomy revealed a loop of gangreous ileum herniated through a right paraduodenal hernia. The compromised bowel was resected and a primary anastomosis was performed. This case report allows us to discuss the diagnostic and therapeutic features of this rare condition.     

Left paraduodenal hernia as a rare cause of acute abdomen

Background

Paraduodenal hernias are congenital internal hernias that emerge as a result of the incomplete fusion of the mesentery with the peritoneum and abnormal intestinal rotation during the stages of foetal development. A rare cause of intestinal obstruction, especially in patients with a medical history free of abdominal operations, paraduodenal hernias account for approximately half of the cases of internal hernias and are responsible for 0.2–0.9% of intestinal obstructions.

Case presentation

We hereby report the case of a 39-year-old female patient who presented with a three-hour episode of acute epigastric pain and nausea. Physical examination revealed tenderness and guarding at the palpation of the epigastrium and the left upper quadrant. Computed tomography was suggestive of an internal hernia at the level of the Treitz ligament.

Results

Emergency laparotomy was performed and the incarcerated jejunal loops were restored back to the abdominal cavity, while the defect at the root of the mesentery was suture closed, with care not to include the inferior mesenteric vein. The post-operative period was uneventful.

Conclusion

Though rare, paraduodenal hernias should be included in the differential diagnosis in cases of acute abdomen or upper bowel obstruction, particularly in the absence of previous abdominal surgery. Surgical treatment is similar to that indicated for any other type of hernia, and involves reduction of the hernia’s contents and elimination of the defect.     

Left paraduodenal hernia causing small bowel obstruction in an adolescent patient

Internal hernias are an uncommon cause of bowel obstruction, accounting for less than 1% of cases. Paraduodenal hernias, the most common type of internal hernias, are believed to be congenital in origin. They can be asymptomatic, cause chronic abdominal pain, or present with acute intestinal obstruction with strangulation and ischemia. We describe a case of left paraduodenal hernia found in a patient who presented with acute intestinal obstruction.     

A massive left paraduodenal fossa hernia as an unusual cause of small bowel obstruction

We present our experience in diagnosing and treating a case of a massive left paraduodenal fossa hernia, containing over 30% of the small bowel, presenting with a history of recurrent incomplete small bowel obstruction.     

A left paraduodenal hernia causing acute bowel obstruction: a case report

We present the case of a 54-year old woman who presented twice at our emergency department with progressive abdominal pain. Over the last few years, multiple short periods of abdominal pain had occurred: the pain always resolved spontaneously after a few hours. She had no past medical history. CT scan revealed a sac-like mass of small bowel loops to the left of the ligament of Treitz, consistent with the diagnosis of a left paraduodenal hernia. On laparotomy, a left paraduodenal hernia with incarceration of small bowel loops was found; the herniated loops were reduced and the hernia orifice closed. The anatomy, treatment and importance of considering this uncommon diagnosis when examining a patient with acute small bowel obstruction are discussed.     

Rare small bowel obstruction: Right paraduodenal hernia. Case report

INTRODUCTIONParaduodenal hernia (paramesocolic hernia), a rare congenital anomaly due to a midgut malrotation during fetal development, is recognized as the most frequent internal hernias. Two variants have been described: left and right, the latter less common than the first one.PRESENTATION OF CASEWe report a right paraduodenal hernia case in a 86 years old female patient who developed an acute bowel obstruction syndrome. Final diagnosis was achieved by imaging techniques as abdomen X-ray and CT and confirmed only after surgical operation.DISCUSSIONSurgical approach was via median laparotomy, consisting in hernia reduction, replacement and stitching of the bowel in its anatomical orientation, and fixing of the posterior wall defect. At 15 months follow-up from surgical procedure the patient is asymptomatic.CONCLUSIONParaduodenal hernia is a rare pathology but its involvement in bowel obstruction syndrome should be always taken into account during diagnostic process.     

Left paraduodenal hernia: a case report

Congenital internal hernias often remain unrecognized since they are infrequent and produce nonspecific abdominal symptoms. Abdominal imaging during a symptomatic episode leads to the diagnosis. Surgical treatment is essential regarding the risks of incarceration. We report a case of left paraduodenal hernia misdiagnosed for over thirty years despite extensive imaging and surgical exploration.     

Recurrent Spigelian hernia: a rare cause of colonic obstruction

Spigelian hernia is considered a surgical rarity. Recent articles describe only six recurrent hernias and a scant number of patients with colonic obstruction resulting from incarceration. A patient with intestinal obstruction resulting from recurrent Spigelian hernia with strangulated colon is described. The patient underwent tension-free repair using a prosthetic mesh. Recent literature suggests that the deficiency of connective tissue in patients with hernias justifies the widespread use of permanent mesh for tissue reinforcement and avoidance of recurrences. The rare case presented should be regarded as an illustrative example for application of the tension-free repair principle in the definitive management of recurrent Spigelian hernia.

Left laparoscopic paraduodenal hernia repair

Background

An internal hernia is a protrusion of bowel through a normal or abnormal orifice in the peritoneum or mesentery. Paraduodenal hernia is by far the most common form of congenital internal hernia, making up 53% of all reported cases. In recent years, as surgeons have become more comfortable with laparoscopic techniques, they are performing an increasing number of these procedures laparoscopically.

Methods

To highlight the technical steps of this technique, the case of a patient with a left paraduodenal hernia and a video of the laparoscopic repair are presented. Additionally, a PubMed search of the English medical literature was conducted using the search words “laparoscopic,” “paraduodenal,” and “hernia” as filters. The cases of laparoscopic paraduodenal hernia repair in the literature to date recording data on technique, complications, and hospital course were reviewed.

Results

In addition to the case described in this report, 14 cases of laparoscopic paraduodenal hernia were described in 10 published reports. Of the 15 cases, 11 (73%) were left-sided, likely representing the relative incidence of these cases. The hernia defect was closed in 10 (77%) of the 13 cases for which the repair method was described, whereas the defect was widely opened in the remaining cases. One report described an operative complication (6.7%), an internal mesenteric vein injury, and one recurrence (6.7%) occurred 18 months after surgery in the direct defect closure group.

Conclusion

The current data lead to the conclusion that laparoscopic paraduodenal hernia repair is a safe and feasible approach for selected patients. It can be expected that as surgeons become increasingly comfortable and facile with laparoscopic techniques, paraduodenal hernias and many other causes of acute small bowel obstruction will be increasingly managed laparoscopically.     

Trichobezoar: A rare cause of bowel obstruction

A bezoar is an intraluminal mass formed by the accumulation of undigested material in the gastrointestinal tract. A trichobezoar is a bezoar made up of hair and is a rare cause of bowel obstruction of the proximal gastrointes-tinal tract. They are seen mostly in young women with trichotillomania and trichotillophagia and symptoms include epigastric pain, nausea, loss of appetite and bowel or gastric outlet obstruction. We herein describe a case of a trichobezoar that presented as a gastric outlet obstruction and was subsequently successfully removed via a laparotomy.     

Mesenteric hernia: a rare cause of intestinal obstruction in children

A 3-year-old boy presented with small bowel obstruction resulting from incarceration of the distal ileum in a mesentric defect. Attempted laparoscopy was unsuccessful. The hernia was reduced successfully at laparotomy. J Pediatr Surg 37:1493-1494.     

Viral small bowel intussusception: a rare cause of intestinal obstruction

Representing a rare cause of bowel obstruction, the ileal intussusception is commonly met in the pediatric surgery. Even if in children's cases the symptoms can mimick a multitude of abdominal syndromes, usually in adult cases the symptoms fit the pattern of the intestinal obstruction. This paper presents 2 clinical cases of small bowel intussusception in adult, the particularity of cases being that the pathogenesis couldn't be established first hand; the pathology exam revealed only minor inflammatory responses,including modest reactive lymph nodes in the vicinity of lesions, without further alterations. The etiology of bowel intussusception was finally attributed to viral infection with gastroenteritis, based on clinical and pathological criteria.     

Left paraduodenal hernia with particular evolution

Paraduodenal hernia is a rare situation, less than 400 cases being published in literature. This condition is difficult to explore, diagnose appear within an occlusive syndrome. The etiopathology involves perturbation of intestinal rotation during the intrauterine life, producing paraduodenal fossa, which generates conditions for internal hernias and occlusive situations. We present the case of a 36 years old woman with chronic epigastric pain, diagnosed as duodenal ulcer, later as acute pancreatitis and in the end as high occlusion syndrome. Open laparotomy was performed, uncovering a strangulated left paraduodenal hernia, with severe pathologic lesions of the intestinal loops. Kelotomy and pure-string suture of parietal defect was performed. Post-operative evolution has been difficult with hepatic failure with coagulopathy and diffuse intestinal hemorrhage, threatening the patient's life. Intensive care lead eventually to a favorable condition. The rarity of this disease, difficulty of diagnosis and the particular evolution were the reasons to present this rare case.     

Ventriculoperitoneal shunt knot: a rare cause of bowel obstruction and ischemia

Small-bowel obstruction caused by knotting of a peritoneal shunt catheter is an extremely rare and severe complication of a ventriculoperitoneal (VP) shunt. In the 1-week-old female infant reported here who had a VP shunt, inability to remove the peritoneal catheter was followed by small-bowel obstruction and necrosis due to intestinal strangulation in a tight loop of the catheter. An uncomplicated primary resection of the necrotic segment was followed by placement of a temporary ventriculoatrial shunt. The authors suggest that when withdrawal of the peritoneal part of a VP shunt meets with resistance, an intraoperative radiograph should be obtained to assess the position of the remaining catheter. If knotting is observed, an attempt to straighten the catheter with a guide wire is worthwhile. Should this fail, immediate laparoscopy or laparotomy is indicated.
