A rare cause of intestinal obstruction: right paraduodenal hernia.

Internal herniation is an extremely rare cause of intestinal obstruction. Paraduodenal hernias result from abnormal rotation of the bowel. Symptoms that may range from recurrent abdominal pain to acute obstruction may occur. If it is not diagnosed and treated in time, the disease may result in intestinal ischemia. This article aimed to present the diagnosis and treatment process of a 47-year-old male presenting with acute abdomen symptoms by evaluating retrospectively with the accompaniment of literature. During the abdominal exploration of the patient, nearly all of the intestines were observed to be herniated from the right paraduodenal region to the posterior area. The opening of the hernial sac was repaired primarily by reducing the intestinal bowel loops into the intraperitoneal region. The patient undergoing anastomosis by performing resection of the ischemic part after reduction of herniated bowel loops was discharged uneventfully on the post-operative 10th day. Paraduodenal hernia is a condition that should be considered in patients with abdominal pain and intestinal obstruction symptoms. Early diagnosis is of vital importance to prevent the complications which can develop.

[Intestinal malrotation accompanied by a right paraduodenal hernia in an adult: a case report].

A 72-year-old woman was admitted to our department in March 2020 for an evaluation of nausea, vomiting, diarrhea, liver dysfunction, and hypokalemia, which had persisted intermittently since 2013. Thickening of the descending duodenal wall and a sac-like appearance the intestinal tract in the vicinity of the duodenal papilla were observed in abdominal computed tomography. No duodenojejunal curvature, with two intestinal loops identified in the descending region, was detected in contrast-enhanced upper gastrointestinal imaging. Based on these imaging findings, the patient was diagnosed with intestinal malrotation (incomplete rotation and fixation) accompanied by a right paraduodenal hernia based on the Nishijima classification. Thus, surgery was performed at our hospital. Gastrointestinal symptoms did not recur, and liver dysfunction and hypokalemia improved postoperatively.

Right paraduodenal hernia, classification, and selection of surgical methods: a case report and review of the literature.

BACKGROUND: Considering that right paraduodenal hernia is a rare internal hernia with abnormal anatomy and is often encountered during an emergency, surgeons may lack knowledge about it and choose incorrect treatment. Thus, this case report is a helpful complement to the few previously reported cases of right paraduodenal hernia. Additionally, we reviewed all the reported right paraduodenal hernia cases and proposed appropriate surgical strategies according to different anatomical features. CASE PRESENTATION: The case involved a 33-year-old Chinese male patient who was admitted to the hospital due to abdominal pain. The patient was initially diagnosed with small bowel obstruction, and conservative treatment failed. An emergency operation was arranged, during which a diagnosis of right paraduodenal hernia was made instead. After surgery, the patient recovered well without abdominal pain for 2 years. CONCLUSION: Although right paraduodenal hernia accounts only for a small proportion of paraduodenal hernia, its anatomical characteristics can vary considerably. We divided right paraduodenal hernia into three types, with each type requiring a different surgical strategy.

Paraduodenal hernia is a rare form of congenital internal hernia and can lead to small bowel obstruction. This case report describes the case of a young boy who was admitted with acute exacerbation of chronic abdominal pain.

Large left paraduodenal hernia identified and repaired by laparoscopy: A case report.

Paraduodenal hernias (PDHs) are rare types of internal hernias that pose a significant diagnostic and therapeutic challenge because they can present with non-specific symptoms ranging from digestive disorders and chronic abdominal pain to symptoms of intestinal obstruction which may be life-threatening. We describe here a woman in her early 30's who presented to the emergency department with a three-hour history of generalized intermittent crampy abdominal pain. She had experienced multiple similar episodes of this pain over the past 20 years. Totally laparoscopic technique was used to complete the diagnosis and treatment of a large left PHD with accompanying acute intestinal obstruction. The operation was successful and the patient was discharged from hospital 10 days later. PDH should be considered if a patient complains of recurrent abdominal pain without any other obvious explanation; a laparoscopic approach can be used to identify and repair the hernia.

Fatal Bowel Obstruction Due to Paraduodenal Hernia: A Case Report.

A paraduodenal hernia is a rare type of hernia, however it is the most common type of internal hernias. It can develop after surgery, trauma, or be congenital. Paraduodenal hernias are rare in children. Clinical presentation is nonspecific. Patients range from being asymptomatic to presenting with clinical symptoms associated with small bowel obstructions. Diagnostic tools such as X-ray, plain abdominal radiography, and computed tomography may be used to diagnose paraduodenal hernias. Described is the case of a 5-year-old female who died suddenly of a bowel obstruction due to a paraduodenal hernia found at postmortem examination. In the hours prior to death, she reported stomach pain, vomiting, and later developed a fever. Postmortem CT study showed free fluid in the abdomen and bowel distention. Internal examination showed an obstructed bowel with ischemic sections extending from the distal portions of the small bowel up to the proximal portions of the transverse colon. The ischemic portions were entrapped within a clear membranous sac within the abdominal cavity. The sac was concluded to be a paraduodenal hernia. Paraduodenal hernias are rare and difficult to diagnose but they must be considered in the diagnostic process, as without surgical intervention the mortality rate can be high.

[Left paraduodenal hernia: a rare cause of acute intestinal obstruction]. / Hernie para duodénale gauche: une cause rare d'occlusion intestinale aiguë.

Left paraduodenal hernia is a congenital internal hernia rarely complicated by acute intestinal occlusion and resulting, sometimes, in life-threatening loops ischemia. We report the case of a 28-year old man treated for occlusive syndrome. Abdominal computerized tomography (CT) scan objectified acute upper intestinal obstruction; intraoperative exploration found jejunal loops incarcerated into left paraduodenal hernia. The neck was closed and the operative suites were simple. Left paraduodenal hernia is often diagnosed when patients have complications. Surgery is the treatment of choice, in particular laparoscopy.

Large left paraduodenal hernia with intestinal ischemia: a case report and literature review.

A left paraduodenal hernia is a rare type of internal hernia but the most common type of peritoneal recess hernia. Preoperative diagnosis of a left paraduodenal hernia is difficult because of its nonspecific clinical manifestations, and it is often confused with other causes of acute abdomen. Diagnosis is therefore often delayed, resulting in serious clinical outcomes. We herein report a case of a large paraduodenal hernia with small intestinal obstruction and ischemia without abdominal pain. The patient was successfully discharged after emergency hernia repair. This case reveals the importance of diagnosing a left paraduodenal hernia with or without abdominal pain, especially in patients with no history of abdominal surgery.
