Morgagni hernia: unique presentations in elderly patients

Bochdalek hernias in the adult population: a systematic review of the literature

BACKGROUND

Bochdalek hernia (BH) is characterized by the protrusion of viscera into thorax through the posterolateral section of the diaphragm. The aim of this study was to systematically review current literature concerning Bochdalek hernias in adults and elucidate their clinical characteristics and preferable treatment approach.

METHODS

A search of PubMed and Cochrane bibliographical databases for studies regarding BHs was conducted (last search: 31st March 2021).

RESULTS

Predefined inclusion criteria were met by 173 articles and concerned collectively 192 patients (50.5% males) with a mean age of 45.41 ± 20.26 years. Abdominal pain (62.0%) and pulmonary symptoms (41.1%) were the predominant symptomatology of included cases. BHs protruded mainly through the left side of the diaphragm (70.7%), with large intestine (42.7%) and stomach (37.1%) being the most commonly herniated abdominal organs. Most patients (53.8%) underwent an open surgical approach, while abdominal approach was preferred (64.8%). to the thoracic one. Thirty-day postoperative complication were encountered at 21.5% of patients, while 30-day mortality reached 4.4%.

CONCLUSION

BH is an extremely rare type of congenital diaphragmatic hernia. It rarely concerns adults, and it manifests with vague gastrointestinal or pulmonary symptoms. Surgical approach is the preferred method for their management with open procedures being preferable at emergency cases, while minimal invasive approach necessitates experienced centers. Further research is needed in order to clarify their true incidence and optimal therapeutic strategy.

Management of Morgagni's Hernia in the Adult Population: A Systematic Review of the Literature

BACKGROUND

Morgagni's hernia (MH) is defined by the protrusion of abdominal viscera through an anterior retrosternal diaphragmatic defect. The objective of this study was to systematically review current literature on MHs in adult population and assess their clinical characteristics and therapeutic approach.

METHODS

PubMed and Cochrane bibliographical databases were searched (last search: 15^th January 2021) for studies concerning MHs.

RESULTS

Inclusion criteria were met by 189 studies that included 310 patients (61.0% females) with an age of 57.37 ± 18.41 (mean ± SD) years. Pulmonary symptoms, abdominal pain, and nausea-vomit were among the most frequent symptomatology. MHs were predominantly right-sided (84.0%), with greater omentum (74.5%) and transverse colon (65.1%) being the most commonly herniated viscera. The majority of cases underwent an open procedure, while 42.3% of patients had a minimally invasive procedure. Abdominal approach was mostly preferred, while a thoracic one was chosen at 20.6% of cases and a thoracoabdominal at 3.2%. Thirty-day postoperative complications were recorded at 29 patients and 30-day mortality was 2.3%.

CONCLUSIONS

MH is a rare type of congenital diaphragmatic hernia which rarely manifests in adult population with atypical pulmonary and gastrointestinal symptoms. Surgery is the gold standard for their management. Open surgical approach is preferable in emergency cases, while laparoscopic surgery is favored in elective setting and is associated with shorter hospitalization. Further studies are crucial in order to elucidate etiology and optimal therapeutic approach.

Symptomatic congenital Morgagni hernia presenting as a chest pain: a case report

Background

Morgagni hernia is a rare form of congenital diaphragmatic hernia with a prevalence of 2–3%. It occurs due to a defect on the anterior part of the diaphragm, which allows abdominal organs to penetrate into the thoracic cavity. This condition can be detected during fetal life by routine ultrasonography or late during adult life. Late diagnosis of this condition in adults is extremely rare. According to our literature search, only a few cases of symptomatic hernia in adults have been reported so far. Surgery provides definitive treatment for patients with Morgagni hernia; it is always recommended for symptomatic and asymptomatic adult patients to avoid future complications such as volvulus, small bowel obstruction, incarceration, or strangulation. We report a case of a patient who presented with chest pain due to newly diagnosed congenital diaphragmatic hernia.

Case presentation

A 29-year-old unemployed white man with no significant past medical history or family history of coronary artery disease, who was a current smoker with a 1-pack-per-day history, presented to our hospital with a 1-month history of intermittent chest pain. His chest pain was localized to the right side with a pressure-like quality, moderate intensity 4–6/10, nonradiating, and relieved by standing up and worsened by lying flat. His pain was not associated with increase or decrease in activity level. The pain had progressively worsened, which prompted the patient to come to the emergency room. The patient was admitted for further evaluation. A chest x-ray showed a suspected loop of bowel on the right side of the chest. Subsequently, the patient underwent computed tomography of the chest, which revealed a 7-cm defect in the right hemidiaphragm with a large amount of intra-abdominal fat and a loop of the proximal transverse colon within the hernial sac. The patient was evaluated by a surgeon and eventually underwent laparoscopic repair of the diaphragmatic hernia with mesh repair. In follow-up, the patient’s symptoms resolved.

Conclusion

Morgagni hernia is a rare form of congenital diaphragmatic hernia. It is commonly found either in the first few hours of life or in the antenatal period. It is less common in adults and is usually diagnosed accidentally in asymptomatic patients. Symptomatic adult cases are extremely rare. Respiratory symptoms are the most common presenting symptoms. The primary management for both symptomatic and incidentally discovered asymptomatic cases of Morgagni hernia is surgical correction. Various thoracic and abdominal surgical approaches have been described without a clear consensus on preference for operative repair technique.

Pericardial Herniation of Small Bowel Post Minimally Invasive Hybrid Maze of Atrial Fibrillation

BACKGROUND

Herniation of intraabdominal contents into the pericardial cavity is exceptionally rare, and when seen, it is most often the result of trauma, postsurgical complication, or genetic defect. There have been only a few case reports describing spontaneous bowel herniation into the pericardium in minimally invasive cardiac procedures like cardiac ablation, pacemaker placement, and minimally invasive coronary artery bypass graft.

CASE REPORT

We report the case of a 65-year-old man who presented to an urgent care center complaining of abdominal and chest pain. This patient had recently undergone a laparoscopic hybrid maze procedure and ultimately had an incarcerated loop of small bowel herniate into the pericardial sac. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: We present this case to increase awareness among emergency physicians of the diagnosis of a pericardial hernia in patients presenting with gastrointestinal or cardiorespiratory symptoms after surgical procedures involving the diaphragm.

Hernia of Morgagni Presenting as Constipation in a 65-Year-Old Male

Hernia of Morgagni is congenital defects in the diaphragm. They are mostly asymptomatic and present with vague symptoms when they do so. A high index of suspicion is required for timely diagnose of this condition. Here we present the case of a 65-year-old male patient presented to our institute with constipation for the past six months. Chest radiology raised the suspicion of a hernia which was further confirmed by contrast studies. Laparotomy was done and the hernia sac identified, colon and greater omentum reduced and defect repaired. He was discharged in stable condition and was doing well on follow-up.

Morgagni's Hernia: Analysis of 21 Patients with Our Clinical Experience in Diagnosis and Treatment

A Morgagni's hernia is a congenital defect found in the anterior aspect of the diaphragm between the costal and the sternal portions of this muscle. This defect is also referred to as the space of Larrey. It has been reported that 70% of patients with Morgagni's hernia are female, 90% of the hernias are right-sided, and 92% of the hernias have hernia sacs. This type of hernia is a rare clinical entity and accounts for 3% of all surgically treated diaphragmatic hernias. There are no large retrospective or prospective studies on this topic. This type of hernia is a rare type among adults without a well-described prevalence and without well-established definitive management strategies. There are also few clinical reports about this clinical entity and its surgical treatment. We treated 21 patients with Morgagni's hernia in a 12-year period, and we report our experience while discussing the surgical treatment of this disease. We performed a retrospective review of the 21 patients who were operated between 2003 and 2015. These patients had undergone surgical repair of Morgagni's hernia. For each subject, demographic data, symptoms of presentation, physical examination findings, preoperative imaging studies and diagnosis, and surgical procedures were documented. Location of the hernia sac and its contents, postoperative complications, and duration of hospital stay were recorded and evaluated. Twelve patients were females and nine were males. The mean age of patients was 63.85 years. Dyspnea was the most prominent symptom in our patients. Morgagni's hernias were located on the right side in 19 patients and on the left side in 2 patients. Chest X-ray in 10 patients and abdominal computerized tomography in 17 patients were the major diagnostic tools. Four patients were operated as emergency while others underwent elective surgery (17 patients). Twelve patients were operated with laparoscopy and the remaining nine were operated with the conventional open abdominal technique. Hernia sacs were observed in all of the patients and removed except in four of them. The omentum and the transverse colon were the most commonly seen organs in hernia sacs. Hernia defects were repaired with primary sutures in four patients (all open cases) and primary closure supported with mesh in six patients (four laparoscopic, two open cases). In the remaining 11 patients, hernia defects were closed with synthetic meshes (eight laparoscopic, three open cases). Mean postoperative hospital stay was 9.8 days. No recurrence was observed in any patients. Only one of our patients died during follow-up. In Morgagni's hernias, surgical intervention is necessary as the hernia may cause complications such as strangulation of the colon or intestines. A laparoscopic approach has increased its popularity in recent years because of the well-known advantages of laparoscopy.

Morgagni hernia presenting as gastric outlet obstruction in an elderly male

Morgagni hernia is the rarest of all congenital diaphragmatic hernias, first described in 1769. It is rarely symptomatic and found on routine radiological examinations for other conditions. Gastric outlet obstruction in adults with Morgagni Hernia is exceedingly rare. An 80-year-old man was taken to the operating room with a diagnosis of Morgagni hernia with gastric outlet obstruction. An upper midline laparotomy was performed, and the incarcerated pylorus and antrum of the stomach reduced with primary closure of the defect. Postoperative period was uneventful, and the patient was discharged on the sixth postoperative day. Morgagni hernia is exceedingly rare in adults and may present with gastric outlet obstruction in the emergency room. This clinical entity should be kept in mind while evaluating the patient, and early surgical intervention should be initiated.

Simultaneous laparoscopic management of Morgagni hernia and cholelithiasis: two case reports

Background

Morgagni hernia is a rare type of diaphragmatic hernia. Though in the past, it has been dealt with an open approach, nowadays laparoscopic management is a favored approach. However, there are few controversies in this scenario.

Case presentation

We present here two females of Aryan ethnicity, one 55 and another 45 years old, who presented with pain at upper abdomen and retrosternal chest pain; on investigations were found to have cholelithiasis along with Morgagni hernia which were managed via the laparoscopic approach in the same sitting.

Conclusion

Repair of Morgagni hernia also via the minimally invasive technique can be offered to the patients like that for cholelithiasis.

Nontraumatic Liver Herniation through a Right–Sided Congenital Diaphragmatic Hernia of Morgagni: An Autopsy Case Report with a Review of Liver Herniations through the Defect and a Review of the Defect

Congenital diaphragmatic hernia of Morgagni (CMH) is a rare developmental defect that develops during the development of the human diaphragm. It is usually right-sided and tends to produce symptoms in later life when abdominal viscera herniate into the chest cavities.

Herniations of the liver through this defect into the chest cavities are rare and are often not clinically suspected even when they are associated with symptoms. The amounts of liver tissue involved are usually small, do not cause symptoms and are often an incidental finding during imaging studies of the chest for unrelated symptoms.

This case report documents a clinically unrecognized incidental herniation of the liver into the right chest cavity through a CMH. The report also reviews previously reported cases of liver herniations through a CMH and the possible causes of the defect.

Morgagni hernia with respiratory failure aggravated by noninvasive positive pressure ventilation: a case report and overview of the literature

An elderly woman diagnosed with multiple myeloma (MM) in 2007 had improved with chemotherapy. She had severe kyphosis and a diaphragmatic hernia (DH), but no respiratory symptoms. In 2011, because of thoracic deformity and emaciation, we advised her to continue the previously prescribed domiciliary noninvasive positive pressure ventilation (NPPV) therapy for chronic type II respiratory failure. However, she refused to continue NPPV. She was later admitted for deterioration in respiratory status and carbon dioxide (CO2) narcosis. We believed her low adherence to domiciliary NPPV caused CO2 narcosis; hence, we advised her to continue domiciliary NPPV and she complied. In May 2012, the now 79-year-old patient was admitted for acute exacerbation of chronic respiratory failure and CO2 narcosis. Chest imaging suggested that DH had caused a deterioration of her status. She underwent laparoscopic diaphragmatic hernia repair. Operative findings revealed a retrosternal hernia sac, and she was diagnosed as having a Morgagni hernia (MH). Her respiratory status subsequently improved. We hypothesize that NPPV increased intra-abdominal pressure, thereby worsening the MH and exacerbating respiratory failure. We believe that clinicians should be cautious when prescribing NPPV for MH patients.

A rare case of morgagni diaphragmatic hernia presenting in pregnancy

A case of Morgagni hernia presenting in adulthood is presented. This form of congenital diaphragmatic hernia is rare in itself and is known to present in adulthood in some cases. But presentation after having undergone three surgeries-PDA ligation, appendicectomy and a full term pregnancy followed by LSCS is even rarer. This case is therefore by any yardstick an extremely rare one.

Atypical right diaphragmatic hernia (hernia of Morgagni), spigelian hernia and epigastric hernia in a patient with Williams syndrome: a case report

INTRODUCTION

Williams syndrome is rare genetic disorder resulting in neurodevelopmental problems. Hernias of the foramen of Morgagni are rare diaphragmatic hernias and they mostly present on the right side, in the anterior mediastinum. They are usually asymptomatic and are difficult to diagnose, especially in patients with learning disabilities.

CASE PRESENTATION

This 49-year-old woman with Williams syndrome, cognitive impairment and aortic stenosis presented to physicians with right-sided chest pain. She had previously undergone repair of her right spigelian and epigastric hernia. Her abdominal examination was unremarkable. Chest X-ray suggested right-sided diaphragmatic hernia and pleural effusion for which she received treatment. The computed tomography scan showed a diaphragmatic hernia with some collapse/consolidation of the adjacent lung. Furthermore, the patient had aortic stenosis and was high risk for anaesthesia (ASA grade 3). She underwent successful laparoscopic repair of her congenital diaphragmatic hernia leading to a quick and uneventful postoperative recovery.

CONCLUSION

These multiple hernias suggest that patients with Williams syndrome may have some connective tissue disorder which makes them prone to develop hernias especially associated with those parts of the body which may have intracavity pressure variations like the abdomen. Diaphragmatic hernia may be the cause of chest pain in these patients. A computed tomography scan helps in early diagnosis, and laparoscopic repair helps in prevention of further complications, and leads to quick recovery especially in patients with learning disabilities. In the presence of significant comorbidities, a less invasive operative procedure with quick recovery becomes advisable.

[Large paraesophageal hernia at risk of torsion in an 84-year-old man]

We describe the diagnosis of a large paraesophageal hernia that showed a risk of torsion in an 84-year-old man who had good health status and no clinical antecedents of interest until the previous night when he woke up and felt dyspnea, some pain located in the epigastrium and a fever spike. After a short interview with ambiguous and inconclusive answers, the main diagnosis was based on the data obtained from the physical examination, the electrocardiogram, the results of the emergency blood tests, and the hydroaerial level that appeared on the standing chest x-ray; acute myocardial infarction and pulmonary embolism were excluded. Once the patient was stabilized, esophagogastroscopy was requested and some hours later the patient underwent the remaining examinations: intestinal transit, opaque enema and computed tomography scan, which are described in the text. The results of these examinations form the basis of a generic discussion about this case and a literature review from point of view of geriatrics. Few cases of large diaphragmatic hernias in octogenarians have been reported in the literature. We discuss the contribution of the techniques used in the diagnosis of this entity.

Surgical technique and complications during laparoscopic repair of diaphragmatic hernias

Diaphragmatic hernias can present as retrocostoxiphoid hernias (RCXH) or diaphragmatic dome hernias. The RCXH include the Larrey hernia (LH), the Morgagni hernia (MH), and the Larrey-Morgagni hernia (LMH). These congenital hernias are usually asymptomatic, and the diagnosis is simplified by two exams: chest X-ray, and thoraco-abdominal computed tomography (CT) scan. The potential risk in this condition is small-bowel incarceration in the hernia defect and subsequent obstruction. We report two cases of LH and one case of LMH treated by laparoscopy between February 2004 and October 2005, with a review of the surgical techniques. Two different laparoscopic techniques were used: the tension-free technique, and resection of the hernia sac with closure of the defect and reinforcement by prosthesis. One patient presented a postoperative cardiac tamponade due to a clip-induced bleeding of an epicardial artery at the inferior surface of the heart. Treatment by laparoscopy is feasible, but a consensus regarding the best laparoscopic repair is needed.

Intestinal Obstruction Caused by a Strangulated Morgagni Hernia in an Adult Patient

A Morgagni hernia is a congenital herniation of abdominal contents into the thoracic cavity through a retrosternal diaphragmatic defect. The reported incidence of congenital diaphragmatic hernias is estimated to be 1 in between 2000 to 5000 births. Morgagni hernias comprise 2% of diaphragmatic hernias. Most Morgagni hernias are found and repaired in children, but 5% are found in adults. They are usually asymptomatic and often found incidentally on chest radiography. Symptoms of these hernias are attributable to the herniated viscera. Morgagni hernias containing bowel may require repair on presentation because of the risk of incarceration. We present a case of an incarcerated and strangulated Morgagni hernia in a 71-year-old woman admitted to our clinic for abdominal pain and symptoms of intestinal obstruction. The diagnosis was made preoperatively by chest radiography, sonography, and computed tomography. Emergent laparotomy was performed, with the herniated transverse colon and omentum reduced into the abdomen. The diaphragmatic defect was repaired, followed by resection of the strangulated omentum. In conclusion, a Morgagni hernia may cause intestinal obstruction. Routine radiographic studies are usually sufficient to arrive at the diagnosis, but a CT scan and sonography may be necessary. Laparotomy is appropriate for the management of symptomatic adult patients with Morgagni hernias, particularly those with findings of intestinal strangulation, with laparoscopic treatment an alternative approach in selected cases.

Clinical presentation and operative repair of hernia of Morgagni

A 77 year old woman who presented with an incarcerated hernia of Morgagni was successfully treated without complications. A Medline search (1996 to date) along with cross referencing was done to quantify the number of acute presentations in adults compared to children. Different investigating modalities--for example, lateral chest and abdominal radiography, contrast studies or, in difficult cases, computed tomography or magnetic resonance imaging--can be used to diagnose hernia of Morgagni. The favoured method of repair--laparotomy or laparoscopy--is also discussed. A total of 47 case reports on children and 93 case reports on adults were found. Fourteen percent of children (seven out of 47) presented acutely compared with 12% of adults (12 out of 93). Repair at laparotomy was the method of choice but if uncertain, laparoscopy would be a useful diagnostic tool before attempted repair. Laparoscopic repair was favoured in adults especially in non-acute cases.

[Diaphragmatic hernia of Morgagni-Larrey in adults: analysis of 10 cases]

Congenital diaphragmatic hernia of Morgagni-Larrey is a rare entity that usually presents on the right side. These hernias, occurring in the anterior midline through the sternocostal hiatus of the diaphragm, are usually discovered incidentally when the patient has reached adulthood, or when they become symptomatic due to intestinal involvement (occlusive symptoms) or when respiratory dysfunction occurs. We present 10 patients (mean age: 69 years) with symptomatic sternocostal hernia and intestinal occlusion. In 7 patients, the hernia was located on the right (Morgagni's hernia) and in three it was located on the left (Larrey's hernia). Most of the patients presented important associated comorbidity, mainly cardiovascular and neoplastic. Surgical treatment consisted of reduction of the contents of the herniated sac and hernia repair through simple suture with or without mesh for reinforcement, mainly through the abdominal approach. Mortality in this series was nil. The infrequency of this entity and its diagnosis mainly in adults, with a high prevalence of circumstances favoring abdominal hernias, suggest that an embryological defect of the sternocostal foramina of Morgagni or Larrey are an essential element in the physiopathology of these processes.

Laparoscopic repair of a Morgagni hernia presenting with syncope in an 85-year-old woman: case report and update of the literature

An 85-year-old woman was transferred from her local hospital for cardiac evaluation after presenting with repeated episodes of syncope during bowel movements. A thorough evaluation revealed no cardiac abnormalities but did reveal a Morgagni hernia with transverse colon in the mediastinum. She underwent laparoscopic reduction of the colon and repair of the hernia with mesh and had a rapid and uneventful recovery.

Half-Fourier acquisition single-shot turbo spin echo imaging in the diagnosis of Morgagni hernia

Magnetic resonance (MR) imaging with multi-planar, gated Half-Fourier Acquisition Single-Shot Turbo Spin-Echo (HASTE) imaging was performed to evaluate a woman with dysrhythmia. MR examination for right ventricular dysplasia revealed a Morgagni hernia. The HASTE images depicted well the diaphragmatic defect and the organs involved, yielding valuable diagnostic and pre-operative information. HASTE imaging may be beneficial in the evaluation of Morgagni hernia.
