Massive symptomatic right-sided Bochdalek hernia in an adult man

Right-sided Morgagni diaphragmatic hernia presenting as isolated left shoulder pain

A woman in her 60s presented to the emergency department with excruciating, deep left shoulder pain and was found to have a right-sided Morgagni hernia, a rare type of congenital diaphragmatic hernia (CDH). She did not have chest pain, palpitations, shortness of breath, cough, abdominal pain, constipation, diarrhoea, nausea, vomiting or other symptoms classically associated with CDHs in adults. Laparoscopic robotic-assisted repair with mesh placement was performed, and the patient's recovery was uncomplicated, with no recurrence of shoulder pain. Our patient's presentation was unusual due to the absence of symptoms typically seen with CDHs in adults, and the presence of contralateral, left-sided shoulder pain with a right-sided Morgagni hernia.

A systematic review on diagnostics and surgical treatment of adult right-sided Bochdalek hernias and presentation of the current management pathway

Purpose

Bochdalek hernia is a congenital diaphragmatic hernia. The incidence in adults is estimated around 0.17%. Right-sided hernias are much more seldom than left-sided ones because of faster closure of the right pleuroperitoneal canal and the protective effect of the liver. Due to its rarity, there have been no large prospective or retrospective studies following great need for evidence-based diagnostics and treatment strategies. In this systematic review, we evaluated the current evidence of diagnostics, treatment, and follow-up of adult right-sided Bochdalek hernias.

Methods

According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines a systematic literature review was conducted in PubMed and Cochrane library from 2004 to January 2021. The literature search included all studies with non-traumatic right-sided Bochdalek hernias. Literature on left- or both-sided, pregnancy-associated, pediatric, and other types of hernias were explicitly excluded. Quality assessment of the included studies was performed.

Results

Database search identified 401 records. After eligibility screening 41 studies describing 44 cases of right-sided non-traumatic Bochdalek hernias in adulthood were included for final analysis. Based upon the systematic literature review, the current diagnostic, therapeutic, and follow-up management pathway for this rare surgical emergency is presented.

Conclusion

This systematic review underlined that most studies investigating management of adult non-traumatic right-sided Bochdalek hernias are of moderate to low methodological quality. Hernias tend to occur more frequently in middle-aged and older women presenting with abdominal pain and dyspnea. A rapid and accurate diagnosis following surgical repair and regular follow-up is mandatory. High-quality studies focusing on the management of this rare entity are urgently needed.

Bochdalek hernia in an adult: two case reports and a review of perioperative cardiopulmonary complications

Background

Bochdalek hernia in an adult is very rare and often needs an immediate surgical repair for the herniation. Although its etiology and surgical techniques have frequently been reported, perioperative complications, especially cardiopulmonary problems, remain unknown. We reported two adults with Bochdalek hernia and reviewed the published literatures with a focus on these issues.

Case presentation

We experienced two adult cases of Bochdalek hernia with gastrointestinal strangulation. One case had massive herniation of the stomach, colon, spleen, and pancreas in the left chest, causing repeated vomiting. The other had a right-side hernia with strangulation of the colon. We successfully performed emergency repairs of these diaphragmatic hernias without any postoperative complications.

Conclusions

Our literature review revealed that life-threatening cardiopulmonary complications, such as empyema or cardiac arrest caused by the tamponade effect of the herniated viscera, sometimes occurred in patients with Bochdalek hernia. These complications were found in Bochdalek hernia with gastrointestinal strangulation.

Diaphragmatic hernia with isolated shoulder pain evoked by surfeit

Bochdalek hernia in adult is extremely rare, so symptoms or indications of surgery are not reported enough. Here we report a case of small-sized Bochdalek hernia with isolated shoulder pain that resolved after surgical reduction of hernia. A 25-year-old man with diaphragmatic mass was referred to out-patient clinic. Chief complaint was an isolated left shoulder pain evoked by surfeit. Diaphragmatic hernia was suggested on chest computed tomography (CT) but it was not certain. So, video-assisted thoracic surgery (VATS) exploration was planned to clarify the diagnosis. The mass was proven to be the Bochdalek hernia and successfully restored into abdominal cavity. There were no postoperative complications and isolated shoulder pain disappeared clearly.

Right-sided Bochdalek hernia in an elderly adult: a case report with a review of surgical management

Background

Bochdalek hernias are one of the most common types of diaphragmatic hernia, with most cases diagnosed during the neonatal period. In contrast, diagnosis of a Bochdalek hernia in an adult is rare and is typically observed on the left side of the diaphragm. Even more rare is the diagnosis of a right-sided Bochdalek hernia in an adult, where there is concurrent visceral malformation in most cases.

Case presentation

We describe a case of an 89-year-old female who presented with abdominal pain. An abdominal computed tomography (CT) scan showed decreased intravenous contrast uptake and thickening of the wall of herniated small intestine through the right side of the diaphragm, which led to the diagnosis of a strangulated diaphragmatic hernia. The patient underwent emergent laparotomy and required a partial resection of the necrotic ileum and a hernia repair with direct closure. Interestingly, in this case, organ malformation was not observed. The patient was discharged approximately 2 weeks after surgery without complication.

Conclusions

Adult right-sided Bochdalek hernia with strangulation in the absence of hepatic atrophy is a rare entity. Considering the severity of this condition, accurate diagnosis and proper treatment are needed. A tailored operative approach is required on an individual case basis.
