Paraduodenal hernia

Paraduonenal hernia constitutes more than 50% of internal hernia cases. It can result in perilous sequelae like gut ischemia and perforation. We report a case of a patient who presented with acute intestinal obstruction and peritonitis and was diagnosed as a case of complicated paraduodenal as an incidental finding on laparotomy.  A 26-year-old male patient presented with three days history of continuous severe incapacitating diffuse abdominal pain. The pain was associated with multiple episodes of bilious vomiting and absolute constipation...

Paraduodenal hernias (PDHs) represent an unusual cause of acute abdominal pain in the Emergency Department (ED) and are associated with high morbidity attributable to a challenging clinical and radiological diagnosis, as signs and symptoms mimic other frequent causes of acute abdominal pain. We report a right paraduodenal hernia in a 37-year-old female patient who presented to the ED complaining of abdominal pain located in the right lower abdomen and hypogastrium, accompanied by nausea. During diagnostic work up, the abdominal computed tomography scan revealed the presence of small bowel malrotation with concomitant right paraduodenal hernia...

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...

BACKGROUND Internal hernias are a rare cause of small bowel obstruction in patients, which usually have a long history of mild abdominal symptoms, sometimes leading to emergency surgery due to acute abdominal pain. Occasionally, it takes a long time to make the correct diagnosis because of symptoms vagueness and transience of typical imaging findings; at times, a definitive diagnosis is possible only through surgery, especially in cases of acute presentations in a low-resource setting where high-performance diagnostic equipment may be unavailable...

INTRODUCTION: Internal hernias are a rare phenomenon, and even rarer is a herniation through the foramen of Winslow. The clinical presentation of patients with an internal hernia is often vague and difficult to diagnose clinically. If internal hernias go undiagnosed and untreated, patients can develop bowel compromise leading to a high morbidity and potential mortality. Radiologic imaging is helpful in bringing the diagnosis to the forefront of the clinicians mind, but the diagnosis is often made intra-operatively...

Paraduodenal hernia (PDH) is a rare congenital anomaly, the most common cause of internal hernia. The left-sided PDHs (LPDHs) are more common than the right-sided and are common in male patients at the 4th and 6th years of life. LPDH is been often clinically asymptomatic and often detected by chance in surgical patients. Abdominal computed tomography is the gold standard in diagnosis. PDH can cause ischemia with the high mortality rates due to intestinal obstruction. Therefore, surgical repair should be done as soon as possible after diagnosis...

BACKGROUND: Malrotation with bowel ischemia is classically thought of as a disease of infants. However, the true prevalence of malrotation in both the pediatric and adult population is unknown due to the unclear number of asymptomatic patients. CASE PRESENTATION: A previously healthy 84-year-old man with no prior abdominal surgeries presented with an acute abdomen and was found on CT to have small bowel located in the right hemiabdomen and an abnormal SMA-SMV relationship suggestive of intestinal malrotation, as well as pneumatosis intestinalis...

INTRODUCTION: Paraduodenal hernia is a rare cause of internal hernia. It is the herniation of small bowel through a peritoneal sac in the duodenum. It occurs due to incomplete rotation and fixation abnormalities of the primitive midgut during fetal development. We report a case of right sided paraduodenal hernia in an adult male. CASE PRESENTATION: This is a case of 36-year-old gentleman who presented with complaints of abdominal fullness and upper abdominal pain for 1...

Internal hernias are quite rare, accounting for fewer than 1% of all abdominal hernias. Moreover, the most frequent cause of internal herniation is paraduodenal hernia (PDH). Diagnosing paraduodenal hernias can be difficult due to the wide range of symptoms that can occur. It is a case report of paraduodenal hernia that was diagnosed and managed in a tertiary center. We describe the case of a 55-year-old male patient who had been experiencing nonspecific abdominal discomfort for the last 5 years and had several comorbidities and positive serology...

A 30-year-old man presented with colicky abdominal pain for 2 months, associated with occasional episodes of bilious vomiting. He had a history of similar complaints at the age of 16 and 26 years. Contrast-enhanced computed tomography abdomen was consistent with a diagnosis of left paraduodenal hernia. On laparoscopy a 3 × 3 cm hernial defect was identified in the left paraduodenal fossa (fossa of Landzert). Contents were jejunal, and proximal ileal loops which were dilated and edematous. Anterior border of the sac was formed by the inferior mesenteric vein and left branch of the left colic artery...

BACKGROUND: Paraduodenal hernia is a rare internal hernia which accounts for only 1% of all intestinal hernias. There have been limited reported cases of paraduodenal hernia treated by laparoscopic surgery. We report a case of left paraduodenal hernia that was successfully treated by single-incision laparoscopic surgery (SILS). CASE PRESENTATION: A 17-year-old woman presented with left upper abdominal pain. An abdominal enhanced multi-detector computed tomography demonstrated encapsulated cluster of small bowel loops in the left upper quadrant which passed through the dorsal side of the inferior mesenteric vein, and showed that blood flow of the prolapsed small bowel was preserved...

Internal hernia is a rare cause of intestinal obstruction, accounting for <2% of cases with paraduodenal type being the most common. An internal hernia, mostly acquired, develops due to protuberance of the intestine through a gap in the peritoneum or mesentery formed as a result of an antecedent abdominal operation such as gastric bypass or liver transplant, ischemic injury, peritonitis, or trauma. Paraduodenal hernias (PDHs) are congenital anomalies, secondary to a failed fusion of mesentery with parietal peritoneum along with rotational midgut errors, causing the evolution of potential space for herniation within the left paraduodenal fossa...

A paraduodenal hernia (PDH) is a rare type of internal hernia, which results from anomalous rotation and reduction of the midgut loop in the embryo. The diagnosis is often difficult due to nonspecific symptoms. The mortality from an acute internal hernia can be close to 50% when the diagnosis and definitive surgical treatment are delayed. Here we present a rare case of obstructed left paraduodenal hernia (LPDH) in a COVID-positive patient. This is probably the earliest report of acute mechanical intestinal obstruction due to LPDH in a COVID-positive patient...

INTRODUCTION AND IMPORTANCE: Internal hernias represent the penetration of intestinal loops through congenital or acquired openings within the mesentery or peritoneum. One such hernia is the paraduodenal hernia, which is the most common type of internal hernia (53%) (Yun et al., 2010) [1]. Due to the variable and non-specific clinical presentation, it is difficult to make a correct diagnosis. Preoperative computed tomography of the abdomen facilitates diagnosis and timely surgical intervention, which can be performed openly or laparoscopically (Coakley et al...

BACKGROUND Internal hernias involve protrusion of the small bowel through a peritoneal or mesenteric space in the abdominal or pelvic cavity. Congenital internal small bowel hernias are rare and patients with them usually present with small bowel obstruction (SBO) at a young age, whereas in older patients, internal small bowel hernias usually are acquired secondary to previous surgery. The present report is of a rare case of SBO due to dual congenital internal small bowel hernias in a 51-year-old man with no history of abdominal surgery...
