Usefulness of Ultrasound in Evaluating the Diaphragm in Neonates and Infants With Congenital Diaphragmatic Hernias

This report describes the evaluations of 2 patients with congenital diaphragmatic hernias using ultrasound (US). Identifying the size of the diaphragmatic defect is important when determining the type of surgical repair required. In case 1, the US evaluation of a Bochdalek hernia showed the rim of the anterolateral diaphragm; therefore, thoracoscopic primary repair was performed. In case 2, (Morgagni‐Larrey hernia), US revealed the left side of a retrosternal diaphragmatic hernia sac; therefore, thoracoscopic repair from the left thorax was performed. Ultrasound was useful for detecting the location and defect size of the diaphragmatic hernia and determining optimal surgical management.     

A case of Spigelian hernia after laparoscopic incisional hernia repair

Laparoscopic ventral hernia repair with intraperitoneal onlay mesh reinforcement is often performed in clinical practice. We herein describe a patient who developed a Spigelian hernia at the edge of the mesh due to rupture of the muscular layer in the abdominal wall. A 69-year-old woman developed a left-sided abdominal bulge 15 months after laparoscopic ventral hernia repair. CT showed a 33-mm defect in the abdominal wall at the lateral edge of the left abdominal rectus muscle with an intestinal prolapse through the defect. She was diagnosed with a Spigelian hernia and underwent operation. The hernia orifice was located at the aponeurosis of the transverse abdominal muscle where the thread had been used to fix the mesh through all layers of the abdominal wall. This report details a case of a Spigelian hernia after laparoscopic ventral hernia repair.     

Single-incision laparoscopic repair for a Morgagni hernia: A case report

A Morgagni hernia is a rare type of congenital diaphragmatic hernia. Here, a case of a Morgagni hernia repaired by SILS is presented. A 78-year-old woman was admitted to our hospital with nausea and vomiting. On CT, the transverse colon and antrum of the stomach were prolapsed into the right thoracic cavity. The herniated stomach was repositioned by emergency endoscopy, and SILS repair was performed electively. Laparoscopy showed the hernial orifice, which was 75 × 50 mm in diameter, on the right side and behind the sternum. Although the transverse colon had herniated through the defect into the right diaphragm, it was easily reduced into the abdominal cavity. Composite mesh was sutured to cover the hernial orifice. No perioperative complications or hernia recurrence have been observed in the 8 months since the surgery.     

Morgagni hernia: a rare form of congenital diaphragmatic hernia.

A congenital diaphragmatic hernia (CDH) occurs in approximately 1 per 2000 pregnancies. Most CDHs that are recognized in utero are of the Bochdalek type, resulting from a posterior defect in the diaphragm. Morgagni hernias result from an anterior defect and are the least common type of CDH (5%). They are rarely seen in utero. Furthermore, when they are seen in utero, they may be mischaracterized. We present a case of an unusual type of Morgagni hernia diagnosed in utero. The type of Morgagni hernia reported here is particularly uncommon. Two cases with similar findings have been reported previously. The shared findings between these cases indicate that, although rare, this may be a recognizable type of CDH and one that is distinguishable from the Bochdalek type.     

Laparoscopic patch repair of a Morgagni hernia in Menkes disease

The association between Morgagni hernia and Menkes disease has not yet been described. Here, we report such a rare association in an 8-year-old boy who presented with subocclusive symptoms. He successfully underwent laparoscopic repair with a patch. The patch was fixed to the anterior abdominal wall by using transfascial sutures with extracorporeal knot tying and to the remaining edges of the diaphragmatic defect by using intracorporeal suturing and spiral tacks. At the 2-year follow-up, the child remained recurrence-free and without gastrointestinal symptoms. The potential relationship between the two conditions and the controversial use of spiral tacks to affix the mesh to the diaphragm are also discussed.     

Reconstructing abdominal wall defects with a free composite tissue flap: A case report

BACKGROUNDReconstructive repair of huge full-thickness abdominal wall defects following debridement for abdominal electric burns remains a clinically challenging task. An ideal abdominal wall repair means a re-closure of the defected abdominal wall with pedicled neurovascular myofascial flaps, restoration of the abdominal wall integrity, and maintenance of the abdominal wall muscle tension to prevent the occurrence of abdominal wall hernia. When treating huge full-thickness defects, composite autologous tissue flaps are a good option for the repair. CASE SUMMARYThis study reported the case of a 43-year-old male patient suffering from full-thickness abdominal wall defects complicated with necrosis of multiple bowel segments and duodenal leak following high-voltage burns involving the left upper limb and abdomen. After debridement for abdominal electric burns and end-to-end anastomosis for the necrotic bowels, reconstruction with acellular dermal matrix grafting and vacuum sealing drainage were performed for temporary abdominal closure. The remaining 18 cm × 15 cm full-thickness abdominal wall defect was repaired using a combined anterolateral thigh and tensor fascia lata free flap. The proposed method achieved the functional reconstruction of the abdominal wall.CONCLUSIONThis approach restored the abdominal wall integrity, maintained certain muscle tension, avoided abdominal hernia, reached satisfactory aesthetic effect, and resulted in no complications in the grafting regions.     

Bochdalek hernia masquerading as a tension pneumothorax

A rare case of congenital diaphragmatic defect presenting with clinical signs of an acute tension pneumothorax is described. The clinical findings were eventually attributable to a herniation of abdominal contents into the chest (Bochdalek hernia). Attempted decompression of the chest by needle thoracocentesis and subsequent introduction of a chest drain caused gastric perforation, requiring repair at laparotomy. It is suggested that if needle thoracocentesis does not result in immediate clinical improvement, or if there is abdominal pain, a portable chest radiograph should be performed before tube thoracostomy to exclude Bochdalek hernia. All emergency department staff should be taught to recognise the radiological appearance of a Bochdalek hernia.     

Laparoscopic intraperitoneal mesh repair of Spigelian hernia: A case report

Spigelian hernia is a rare congenital defect of the anterior abdominal wall located along the semilunar line through the aponeurosis fascia of the transversus abdominis muscle. It represents 1%–2% of all abdominal wall hernias. Few cases of laparoscopic treatment for Spigelian hernia have been reported, especially in Japan. However, several reports of laparoscopic surgery to repair Spigelian hernias have been published, and some have shown that the laparoscopic approach repair is feasible because it is associated with less morbidity and a shorter hospital stay than open surgery. We herein describe a 63‐year‐old Japanese woman who presented with painful bulging in the right lower abdominal quadrant. A preoperative diagnosis of Spigelian hernia was made, and we performed laparoscopic intraperitoneal repair. The patient was discharged 6 days after laparoscopic surgery with no perioperative complications. This report describes the first successful laparoscopic intraperitoneal mesh repair of Spigelian hernia in Japan.     

Thoracoscopic repair for late-presenting congenital diaphragmatic hernia with thoracic kidney in a child

Congenital diaphragmatic hernia (CDH) with a hernia sac and thoracic kidney is a very rare congenital anomaly. Recently, the usefulness of endoscopic surgery for CDH has been reported. We herein report a patient who underwent thoracoscopic repair of CDH with a hernia sac and thoracic kidney. A 7-year-old boy was referred to our hospital due to a diagnosis of CDH without clinical symptoms. Computed tomography showed herniation of the intestine into the left thorax and left-sided thoracic kidney. The key points of operation are resection of the hernia sac and identification of the suturable diaphragm under the presence of the thoracic kidney. In the present case, after repositioning the kidney to the subdiaphragmatic area completely, the border of the diaphragmatic rim was clearly visualized. Good visibility allowed resection of the hernia sac without damaging the phrenic nerve and closure of the diaphragmatic defect.     

The antenatal diagnosis of diaphragmatic anomalies

In an evaluation of eight fetal diaphragmatic anomalies a number of suggestive antenatal ultrasound findings were identified. The feature most suggestive of a posterolateral hernia (foramen of Bochdalek) is malposition of the heart. Peristalsis of chest contents or movement of abdominal contents into the chest on inspiration are more specific findings. Absence of an intra-abdominal stomach, a small abdominal circumference, and a cystic or solid mass in the chest are suggestive but not specific. It may be difficult or impossible to distinguish a posterolateral diaphragmatic defect from the much less frequent eventration of the diaphragm. An anteromedial defect of the diaphragm (foramen of Morgagni) presented as an intrathoracic anterior solid mass and should be considered in the differential diagnosis of an anterior chest mass. Although all three types of defects are frequently associated with additional anomalies, severe pulmonary hypoplasia is not a complication of eventration or anteromedial defects.     

Thoracoscopic repair of a large neonatal congenital diaphragmatic hernia using Gerota's fascia

A large congenital diaphragmatic hernia needing patch repair has a high risk of recurrence. Thus, managing these large congenital diaphragmatic hernias under thoracoscopy has become a problem. Here, a large congenital diaphragmatic hernia that was repaired using Gerota's fascia under thoracoscopy is reported. In the present case, it was impossible to close the hernia directly under thoracoscopy because the hernia was too large. Gerota's fascia was raised up by the left kidney and used for the repair. The left colon adhering to Gerota's fascia was mobilized, and a large space was made under thoracoscopy. Gerota's fascia was fixed to the diaphragmatic defect. The patient's postoperative course was good, and there was no recurrence. This technique could be one option for repairing a large hernia under thoracoscopy.     

A case of diaphragmatic hernia incarceration after a heart transplant operation

We report a case of a diaphragmatic hernia after a heart transplant operation. A 43-year-old woman, who underwent orthotropic heart transplantation for hypertrophic cadiomyopathy two year earlier, presented with vomiting and epigastric pain. A computed tomography scan showed that the stomach and transverse colon were dislocated in the left thoracic cavity. We diagnosed left diaphragmatic hernia incarceration and performed laparoscopic repair of the diaphragmatic hernia. A 12 × 8 cm diaphragmatic defect was found intraoperatively on the ventrolateral aspect of the left diaphragm, and the stomach with volvulus had herniated into the thorax through the defect. The hernia was considered to be iatrogenic. The diaphragmatic defect was large, and the diaphragm was thinning. We closed the defect by mesh repair. Laparoscopic mesh repair of the diaphragmatic hernia could be performed safely and with minimal invasiveness.     

Laparoscopic mesh repair of a Morgagni hernia using the double‐crown technique: A case study

We report a case of Morgagni hernia in which the patient underwent laparoscopic mesh repair. A 65‐year‐old woman presented with an abnormal shadow in the right lower lung field on a routine medical checkup. CT showed that the transverse colon passed between the liver and abdominal wall, and herniated into the thoracic cavity. Simple closure was precluded by the large hernial orifice. We therefore performed laparoscopic repair using a Parietex Optimized Composite Mesh. The double‐crown technique was used to fix the margin of the mesh to the region around the hernial orifice. Our procedure for repair of a Morgagni hernia with a large hernial orifice is safe and minimally invasive, and it may effectively prevent recurrence.     

Tension gastrothorax complicating acute traumatic diaphragmatic rupture.

Herniation of abdominal viscera into the thorax following traumatic diaphragmatic hernia can simulate acute tension pneumothorax. A case is presented of a blunt trauma victim with apparent acute diaphragmatic rupture, tension hemothorax, or tension hemopneumothorax. Nasogastric tube insertion demonstrated tension gastrothorax, but was followed by acute clinical decompensation. Percutaneous needle thoracostomy decompressed the stomach without causing spillage of gastric contents. Autopsy experimentation was performed to demonstrate that needle decompression of the distended stomach is well tolerated. Tension gastrothorax is a rare, life-threatening complication of traumatic diaphragmatic hernia. Although nasogastric tube placement should be attempted first, it may exacerbate the condition. Percutaneous needle decompression of the stomach through the chest wall can stabilize the situation and is safer and more rapid than chest tube placement, which might be either ineffective or dangerous. Paralyzing the patient with acute diaphragmatic rupture before tracheal and gastric intubation might prevent progression to tension gastrothorax.     

Left diaphragmatic eventration diagnosed as congenital diaphragmatic hernia by prenatal sonography

Congenital diaphragmatic eventration is an abnormal elevation of the diaphragm resulting from failure of muscle fibers to develop during gestation. A mediastinal shift to the contralateral side may cause significant compression of the affected chest contents, resulting in compromised pulmonary function, especially when both sides are involved. Differentiating between congenital diaphragmatic eventration and congenital diaphragmatic hernia is very difficult but important because eventration has a better perinatal outcome than diaphragmatic hernia has. This report discusses a case of congenital diaphragmatic eventration that was initially diagnosed by prenatal sonography as a diaphragmatic hernia on the left side. In this case, the correct diagnosis was made at the time of surgery shortly after the infant's birth. The defect was repaired by plication, and the infant's outcome was favorable. Although the initial diagnosis was incorrect in this case, the use of sonography can aid in the prenatal detection and diagnosis of congenital diaphragmatic anomalies.     

Abdominal circumference in fetuses with congenital diaphragmatic hernia: correlation with hernia content and pregnancy outcome.

To assess the value of abdominal circumference measurements in the second trimester as a predictor of mortality in fetuses with congenital diaphragmatic hernia, 34 fetuses with this condition who had had second trimester ultrasonographic evaluation were analyzed retrospectively for abdominal circumference measurements, content of the hernia, and pregnancy outcome. The abdominal circumference was below the fifth percentile in nine of the 27 fetuses (33%) with an isolated defect and in five of the seven fetuses (71%) with additional anomalies. In fetuses with isolated congenital diaphragmatic hernia, an abdominal circumference measurement below the fifth percentile was associated with the presence of the liver (P < 0.05) but not of the stomach in the chest. In 19 continuing pregnancies with an isolated defect, all five fetuses with an abdominal circumference below the fifth percentile either died prenatally (n = 1), soon after birth (n = 1), or after surgery (n = 3). In contrast, only six of the 14 fetuses (43%) with an abdominal circumference measurement within the normal range died, either soon after birth (n = 2) or after surgery (n = 4) (P < 0.05). We conclude that an abdominal circumference measurement below the fifth percentile in the second trimester appears to be a good predictor of a poor prognosis in fetuses with congenital diaphragmatic hernia.     

Gastric Volvulus Through Morgagni Hernia: An Easily Overlooked Emergency

Background

Intractable vomiting in an elderly patient is an emergency condition requiring prompt diagnosis and intervention. Acute gastric outlet obstruction due to gastric volvulus through Morgagni-type diaphragmatic hernia is an exceedingly rare cause of this nonspecific complaint.

Objective

Our aim was to highlight that Morgagni hernia, although rare in adults, should be suspected in the appropriate clinical setting, and that a clue toward diagnosis often comes from routine chest and abdominal x-ray studies. In addition, we emphasize the atypical radiological findings and importance of emergency surgical intervention in such a case.

Case Report

We describe the case of a 78-year-old woman who presented to the Emergency Department with a 4-day history of intractable vomiting, and with no definitive clue to the diagnosis on examination. Her routine chest and abdomen x-ray studies suggested abnormal air-fluid level at right hemithorax, which prompted a computed tomography (CT) scan of the abdomen and an upper gastrointestinal contrast study. Gastric volvulus through a foramen of Morgagni was diagnosed and transthoracic reduction of the contents was performed, along with repair of the defect.

Conclusions

A symptomatic Morgagni hernia in adults, although rare, can present with a variety of symptoms ranging from nonspecific complaints of bloating and indigestion to the more severe complaint of intestinal obstruction. Gastric volvulus and obstructive features are less frequently reported as acute complications of these hernias, which need early identification and intervention.     

Traumatic intermuscular hernia in the anterior abdominal wall.

Traumatic ventral herniae are uncommon. The authors present a patient with traumatic intermuscular hernia in the anterior abdominal wall. Early recognition and differentiation from haematoma is important. In this case, the overlying intact muscle layer masked the classical clinical signs. The incision should be adequate and all internal organs carefully examined. Primary repair is usually possible.     

Gastric volvulus associated with congenital diaphragmatic hernia, wandering spleen, and intrathoracic left kidney: CT findings

We present an unusual case of gastric volvulus associated with wandering spleen, a delayed manifestation of congenital diaphragmatic hernia and left intrathoracic kidney. Gastric volvulus should be considered in any infant with unexplained vomiting and left diaphragmatic anomaly: in these patients, developmental disorders of the peritoneal visceral attachments of the left upper abdomen may coexist. The absence of ligamentous connections between the stomach, posterior abdominal wall, and spleen result in wandering spleen. We emphasize prompt surgical therapy to avoid gastric and splenic necrosis. Radiologic findings and the appearance of this complex congenital malformation are reported.
