Bochdalek hernia in the adult: demographics, presentation, and surgical management

Congenital Hernias in Adults: Bochdalek Hernias

Bochdalek hernias are a rare occurrence in adults and usually asymptomatic, resulting in incidental discovery. However, surgical intervention is recommended for both symptomatic and asymptomatic Bochdalek hernias due to the risk of acute morbidity and mortality. There are various possible surgical approaches that may be appropriate depending on the circumstance, with robotic repair becoming increasingly popular. To date, the rarity of the condition has limited the available data on postoperative outcomes.

Reduced Long-Term Bowel Obstruction Risk With Minimally Invasive Diaphragmatic Hernia Repair

INTRODUCTION

The introduction of minimally invasive surgery (MIS) for repair of congenital diaphragmatic hernias (CDH) has reduced postoperative length of stay, postoperative opioid consumption, and provided a more esthetic repair. In adult abdominal surgery, minimally invasive techniques have been associated with decreased long-term rates of small bowel obstruction (SBO), although it is unclear if this benefit carries over into the pediatric population. Our objective was to evaluate the rates of SBO following open versus MIS CDH repair.

MATERIAL AND METHODS

Infants who underwent CDH repair between 2010 and 2021 were identified using the PearlDiver Mariner database. Kaplan-Meier curves and Cox proportional hazards models were used to evaluate time to SBO by surgical approach (MIS versus open) while adjusting for mesh use, patient sex, and length of stay.

RESULTS

Of 1033 patients that underwent CDH repair, 258 (25.0%) underwent a minimally invasive approach. The overall rate of SBO was 7.5% (n = 77). Rate of SBO following MIS repair was lower than open repair at 1 y (0.8% versus 5.1%), 3 y, (2.3% versus 9.0%), and 5 y (4.4% versus 10.1%, P = 0.004). Following adjustment, the rate of SBO following MIS repair remained significantly lower than open repair (adjusted hazard ratio: 0.37, 95% confidence interval: 0.18, 0.79).

CONCLUSIONS

Following CDH repair, long-term rates of SBO are lower among patients treated with MIS approaches. Long-term risk of SBO should be considered when selecting surgical approach for CDH patients.

Rare Diaphragmatic Hernias in Adults-Experience of a Tertiary Center in Esophageal Surgery and Narrative Review of the Literature

A rare entity of non-hiatal type transdiaphragmatic hernias, which must be clearly differentiated from paraoesophageal hernias, are the phrenic defects that bear the generic name of congenital hernias-Bochdalek hernia and Larey-Morgagni hernia, respectively. The etiological substrate is relatively simple: the presence of preformed anatomical openings, which either do or do not enable transit from the thoracic region to the abdominal region or, most often, vice versa, from the abdomen to the thorax, of various visceral elements (spleen, liver, stomach, colon, pancreas, etc.). Apart from the congenital origin, a somewhat rarer group is described, representing about 1-7% of the total: an acquired variant of the traumatic type, frequently through a contusive type mechanism, which produces diaphragmatic strains/ruptures. Apparently, the symptomatology is heterogeneous, being dependent on the location of the hernia, the dimensions of the defect, which abdominal viscera is involved through the hernial opening, its degree of migration, and whether there are volvulation/ischemia/obstruction phenomena. Often, its clinical appearance is modest, mainly incidental discoveries, the majority being digestive manifestations. Severe digestive complications such as strangulation, volvus, and perforation are rare and are accompanied by severe shock, suddenly appearing after several non-specific digestive prodromes. Diagnosis combines imaging evaluations (plain radiology, contrast, CT) with endoscopic ones. Surgical treatment is recommended regardless of the side on which the diaphragmatic defect is located or the secondary symptoms due to potential complications. The approach options are thoracic, abdominal or combined thoracoabdominal approach, and classic or minimally invasive. Most often, selection of the type of approach should be made taking into account two elements: the size of the defect, assessed by CT, and the presence of major complications. Any hiatal defect that is larger than 5 cm2 (the hiatal hernia surface (HSA)) has a formal recommendation of mesh reinforcement. The recurrence rate is not negligible, and statistical data show that the period of the first postoperative year is prime for recurrence, being directly proportional to the size of the defect. As a result, in patients who were required to use mesh, the recurrence rate is somewhere between 27 and 41% (!), while for cases with primary suture, i.e., with a modest diaphragmatic defect, this is approx. 4%.

Maternal Strangulated Diaphragmatic Hernia with Gangrene of the Entire Stomach During Pregnancy: A Case Report and Review of the Recent Literature

Background

Bochdalek hernia (BH) of congenital diaphragm hernia is infrequently seen in adults. Strangulation of the diaphragm hernia has been recognized as a severe complication. Among several factors, pregnancy is an important cause of diaphragm hernia's deterioration. However, nausea, vomiting, and upper abdominal pain are often considered non-specific pregnancy-related symptoms.

Case Presentation

We report a case of a 39-year-old (gravida II, para I) multigravida woman with a delayed diagnosis of strangulated herniated viscera complicating total gastric gangrene at 26+1 weeks' gestation. The preoperative diagnosis was confirmed by an X-ray examination and magnetic resonance imaging (MRI). After identifying the size and severity of the herniated contents through video-assisted thoracoscopy (VAT), we immediately converted to abdominal laparotomy. Antenatal corticosteroids were administered simultaneously with diagnosis to promote fetal maturity. The fetal condition was maintained well in the maternal uterus during the operation. Careful monitoring of the fetus and the mother's clinical conditions should be performed during expectant management to achieve delayed delivery after maternal surgical correction. Delivery was completed through cesarean delivery at 27+1 weeks of gestation.

Conclusion

Despite the rarity of maternal Bochdalek hernias during pregnancy, early diagnosis and appropriate treatment via multidisciplinary care are essential for maternal and fetal outcomes.

Bochdalek hernia presenting as recurrent fever and bicytopenia in a pediatric patient: A rare case report

Bochdalek hernia is a rare condition characterized by the displacement of abdominal contents into the thoracic cavity. Due to the nonspecific nature of symptoms, prompt diagnosis, and management by emergency care providers can be challenging. Treatment of a Bochdalek hernia typically involves the reduction in the herniated contents back into the abdominal cavity. In this case report, we present the case of a 1-year-old girl who presented to the emergency department with a fever and bicytopenia. Further evaluation revealed a Bochdalek hernia, which was successfully managed with surgical intervention. This case highlights the importance of considering a Bochdalek hernia in the differential diagnosis of patients presenting with recurrent nonspecific symptoms (fever and bicytopenia).

Late presentation of a congenital problem; complicated left-sided Bochdalek's hernia in an adult: A case report

Background

A diaphragmatic hernia is a defect or hole in the diaphragm through which abdominal contents can enter the chest cavity. Diaphragmatic hernias may be congenital (Morgagni hernia, Bochdalek hernia), a hiatal hernia, or acquired (iatrogenic and traumatic). Bochdalek's hernia typically occurs on the left side and rarely occurs in adults. Less than 100 cases of left Bochdalek's hernia in adults have been described in the literature. Most of them are asymptomatic.

Case report

We report a complicated left Bochdalek hernia in a 43-year-old adult male who is a smoker. He came to the pulmonary clinic with symptoms and signs of pneumonia of the left lower lobe with persistent dyspeptic symptoms. Chest radiography revealed evidence of a left diaphragmatic hernia, which was confirmed by computed tomography of the chest and abdomen, and subsequently treated by left diaphragmatic repair via limited left thoracotomy.

Conclusion

We report a rare case of a left Bochdalek hernia in an adult who underwent an appropriate left thoracotomy. Bochdalek hernias in adults are rare and usually asymptomatic, but when they become symptomatic, surgical intervention is required to avoid complications. BH should be considered in the differential diagnosis when radiographs suggest pneumothorax and should be treated early to avoid complications.

Management of complicated diaphragmatic hernia in the acute setting: a WSES position paper

BACKGROUND

Diaphragmatic hernia (DH) presenting acutely can be a potentially life-threatening condition. Its management continues to be debatable.

METHODS

A bibliographic search using major databases was performed using the terms "emergency surgery" "diaphragmatic hernia," "traumatic diaphragmatic rupture" and "congenital diaphragmatic hernia." GRADE methodology was used to evaluate the evidence and give recommendations.

RESULTS

CT scan of the chest and abdomen is the diagnostic gold standard to evaluate complicated DH. Appropriate preoperative assessment and prompt surgical intervention are important for a clinical success. Complicated DH repair is best performed via the use of biological and bioabsorbable meshes which have proven to reduce recurrence. The laparoscopic approach is the preferred technique in hemodynamically stable patients without significant comorbidities because it facilitates early diagnosis of small diaphragmatic injuries from traumatic wounds in the thoraco-abdominal area and reduces postoperative complications. Open surgery should be reserved for situations when skills and equipment for laparoscopy are not available, where exploratory laparotomy is needed, or if the patient is hemodynamically unstable. Damage Control Surgery is an option in the management of critical and unstable patients.

CONCLUSIONS

Complicated diaphragmatic hernia is a rare life-threatening condition. CT scan of the chest and abdomen is the gold standard for diagnosing the diaphragmatic hernia. Laparoscopic repair is the best treatment option for stable patients with complicated diaphragmatic hernias. Open repair is considered necessary in majority of unstable patients in whom Damage Control Surgery can be life-saving.

Laparoscopic Repair of Bochdalek Hernia: A Rare Presentation of Abdominal Pain in the Elderly

Bochdalek hernias (BHs) are rare, and the presentation, diagnosis, and management of them can be complex. We present a 70-year-old man presenting with left flank pain who underwent a successful laparoscopic repair of BH with mesh placement.

Case reports: a variety of clinical presentations and long-term evolution of Bochdalek hernias

Bochdalek hernias are the most common congenital diaphragmatic hernias, followed by Morgagni hernias. The failure of closure of the pleuroperitoneal membrane results in a posterolateral foramen, which can remain silent until adulthood. They remain a rare pathology with nearly a hundred cases published. Its clinical presentation is variable, making its diagnosis challenging for clinicians. Additionally, its symptoms are not necessarily representative of the content of the hernia. Its management is balanced between the abdominal and the thoracic approaches. However, no guidelines or algorithms are available to help surgeons in the decision-making process. We report here four consecutive cases of symptomatic Bochdalek hernias. Each case has a singular presentation, and we share how they were approached at our institution. In particular, this series shows no reoccurrence in 10+ years of follow-up in two cases and 20+ in one case, underlying the importance of surgical management when Bochdalek hernias are symptomatic.

Difficult airway management and low Bispectral Index (BIS) in a patient with left Bochdalek congenital diaphragmatic hernia (CDH)

BACKGROUND

Bochdalek congenital diaphragmatic hernia (CDH) is a developmental defect in the posterolateral diaphragm, allowing herniation of abdominal contents into the thorax causing mechanical compression of the developing lung parenchyma and lung hypoplasia. We describe a case of an adult patient with a Bochdalek hernia who underwent minimally invasive right thoracotomy Perceval bioprosthetic aortic valve replacement (AVR) requiring one-lung ventilation (OLV) on the side of the hernia. This is a complex and challenging case that brings up numerous thought-provoking anesthetic implications. To the best of our knowledge, a Pubmed search did not reveal any publication to date of difficult airway management in an adult patient with CDH.

CASE PRESENTATION

The first major problem encountered was patient's crus habitus anatomical condition (exceedingly ventrally displaced trachea) Mallampati Class IV and Cormack-Lehane grade IV extremely difficult endotracheal intubation. Neither glottis nor epiglottis was visible on laryngoscopy; resulting in failed placement of the double-lumen endobronchial tube (DLT) following numerous attempts. The DLT was eventually placed via GlideScope videolaryngoscopy. Whereas the endobroncheal right lung block for left OLV was successfully placed using fiberopticscopy. The crus habitus encroached on OLV tidal volume by the cranially displaced ascending colon and left kidney. Anesthesia was maintained with remifentanil /sevoflurane; adjusted to maintain bispectral index (BIS) at 40-60. Digitally recorded BIS was 38-62 except when BIS precipitously declined to 14-38 (SR, suppression ratio < 10) for 25 min after termination of the cardiopulmonary bypass.

CONCLUSIONS

We report a case essentially dealing with an anatomically distorted difficult airway in a patient with left Bochdalek CDH undergoing a complex AVR. We describe anesthetic difficulties and unforeseen issues encountered; such as an extremely difficult DLT placement.

Thoracic kidney nephrectomy due to recurrent Bochdalek hernia in an adult

Congenital diaphragmatic hernia incidence is one in 3000 live births, Bochdalek hernia occurs through a posterolateral defect. It is very rare in adults. We present a case of late relapsed one diagnosed in an adult male. He underwent an open intervention of Bochdalek hernia at first day of life and required reintervention at seventh month due to recurrence. Now, computerized tomography scan demonstrates a right diaphragmatic defect with intrathoracic hydronephrotic kidney. Nephrectomy was performed with Video-assisted Thoracic Surgery using laparoscopic ports and material. The diaphragmatic defect was closed with a polypropylene mesh. The patient was discharged after 72 h.

Obstructed Bochdalek hernia in an adult

Congenital diaphragmatic hernia is a common neonatal anomaly. Presentation beyond childhood, however, is rare. We report, here, the case of a woman in her 50s who presented with an acutely obstructed posterolateral diaphragmatic hernia. The initial physical exam and radiological results could have led to an erroneous diagnosis of pneumothorax. We wish to emphasize the importance of having a high index of suspicion for this condition when cases with similar gastro-respiratory symptoms are encountered.

Congenital diaphragmatic hernia in adults: a decade of experience from a single tertiary center

INTRODUCTION

Congenital diaphragmatic hernias (CDHs) in adults remain rare, with limited data on them available. However, CDHs can cause respiratory and gastrointestinal symptoms in adults, even resulting in the strangulation of the bowel when incarcerated. Here, we aimed to analyze surgical outcomes among adult patients. The primary outcome of interest was the complication rate, reoperations and 90-day mortality after laparoscopic and open hernia repair.

METHODS

We identified all adult patients diagnosed with a Morgagni or Bochdalek hernia treated operatively between 2010 and 2019 in a single tertiary care hospital. Data on patient demographics, surgical characteristics, mortality and morbidity were collected.

RESULTS

In total, we identified 37 patients (67.6% female; average age, 57 years). Overall, 78.4% patients underwent minimally invasive operations, while 35.1% underwent emergency operations. A Clavien-Dindo grade II-V complication was experienced by 18.9% of patients. No deaths occurred within 90 days of surgery, and we detected no recurrences in short-term or long-term follow-up. A minimally invasive technique correlated with a shorter hospital stay of 3.6 days versus 6.8 days in the open surgery group (p = .007, t = 3.3, 95% confidence interval = 1.04-5.21).

CONCLUSION

Our findings indicate that the laparoscopic repair of a congenital diaphragmatic hernia is safe and effective, offering short hospital stay and a low amount of complications.

Robotic repair of a giant Larrey-type congenital left-sided diaphragmatic hernia in a young woman. A case report and literature review

Congenital diaphragmatic hernia is a rare condition caused by a malformation in the diaphragm that is usually diagnosed in newborns, infants and children. Sometimes it can be incidentally identified in adults. Once the diagnosis is made, surgery is indicated to avoid the risk of life-threatening complications of herniated viscera. Traditional approaches include laparotomy or thoracotomy or both; in the last decades minimally invasive techniques have proved to be a safe alternative to the open approach but only few cases of robotic hernia repair have been described so far, the most with a combined thoracic-abdomen approach. We report a case of an 18-year-old female presenting with abdominal pain due to a giant left-sided anterior diaphragmatic hernia (Larrey-type) that was repaired using a robotic-assisted laparoscopic approach with mesh placement. The hernia contents included gastric body and fundus, duodenum, jejunum, ileus, cecum, right colon and mesentery; spleen and pancreas were rotated and dislocated anteriorly. The outcome was unremarkable, with no major post-operative complications and no signs of long-term recurrence. The robotic approach seems to be a valid option for the treatment of diaphragmatic hernias, improving post-operative outcome and providing surgeon better visualization, greater precision and enhanced dexterity in a confined space.

•

Congenital diaphragmatic hernias are a rare condition that may have a late onset.

•

Once the diagnosis is made, surgery is mandatory due to the risk of life-threatening complications.

•

Minimally invasive approaches are a safe option for congenital diaphragmatic hernia repair and can improve post-operative outcome.

•

Robotic diaphragmatic hernia repair allows better visualization, greater precision and enhanced dexterity in a confined space.

•

The use of a mesh is controversial, but in large defects it is recommended to reinforce the primary repair.

Intrathoracic kidney: A rare presentation of ectopic kidney

The thoracic kidney is the rarest form of renal ectopia. Furthermore, it is usually asymptomatic and discovered incidentally. It is seen as a mass in the posterior mediastinum or juxta-diaphragmatic on chest radiography. A computed tomography scan or magnetic resonance imaging is usually needed for a definitive diagnosis. The thoracic kidney typically exits the retroperitoneal space through the foramen of Bochdalek.

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.

Case Report: Adult Right-Sided Bochdalek Hernia Complicated by Intrathoracic Bowel Perforation

Right-sided Bochdalek hernia is a mostly congenital condition of the diaphragm caused by a persistence of the pleuroperitoneal cavity and a rare disease in adults. As it often presents as an emergent situation, urgent diagnostics and surgical intervention are essential to reduce morbidity and mortality rates. Choosing the right surgical approach (abdominal, thoracic, or a combination of both) can be very challenging for clinicians. Here, we report a case of a 40-year-old woman, who presented with severe abdominal pain and tachypnoea. Imaging revealed a right-sided Bochdalek hernia. Emergency laparotomy was performed followed by reduction of hernia content, right-sided hemicolectomy, and side-to-side anastomosis from the ileum to the transverse colon due to intestinal ischemia and intrathoracic bowel perforation. The post-operative course was complicated by a pleural empyema. Therefore, the patient underwent thoracotomy. One year after surgical repair the patient had no recurrence. Here, we discuss feasible approaches for the surgical management of complicated Bochdalek hernias.

Bochdalek Hernia with Gastric Necrosis Requiring Roux-en-Y Esophagojejunostomy

Bochdalek hernias are the most common congenital diaphragmatic hernias and are usually diagnosed during childhood¹. They can present in adulthood and, in uncommon circumstances, result in gastric herniation with strangulation. We present a case of an adult Bochdalek hernia resulting in total gastric necrosis necessitating Roux-en-Y esophagojejunostomy in an otherwise healthy 39-year-old male. This case highlights the potential morbidity associated with unrepaired congenital diaphragmatic hernias and the need for appropriate referral.

Combined laparoscopic and thoracoscopic surgical repair of Bochdalek hernia in an adult: a case report

BACKGROUND

Bochdalek hernia is a rare disease in adults. Diaphragmatic hernia in adults has been repaired using minimally invasive surgery through laparoscopy or thoracoscopy. However, the literature regarding the combined use of laparoscopy and thoracoscopy for the repair of Bochdalek hernia is limited.

CASE PRESENTATION

A 26-year-old man diagnosed with Bochdalek hernia was managed through combined abdominal and thoracic endoscopic surgery. On laparoscopy, the omentum prolapsed into the left thoracic cavity through the posterolateral area of the left diaphragm. On thoracoscopy, no adhesions of the omentum were seen in the thoracic cavity. The omentum was drawn back to the abdominal cavity, and a 4 × 3-cm hernial orifice was identified. The hernia orifice was repaired through simple closure with sutures laparoscopically. The patient's postoperative course was uneventful with no recurrences within the first year post-surgery.

CONCLUSION

Combined laparoscopic and thoracoscopic surgery is a safe and effective method for Bochdalek hernial repair in adults.

Right-sided Bochdalek hernia in an adult: a case report

Bochdalek hernia (BH) is the most common type of congenital diaphragmatic hernia and is usually left-sided. It typically presents in neonates and diagnosis in adults is a rarity. To date only 34 reported cases of right-sided BH have been surgically managed in adults in literature. We review a 21-year-old female with a right-sided BH diagnosed as acute calculus cholecystitis and underwent laparoscopic cholecystectomy. The diagnosis of BH was made incidentally during surgery. The hernia did not have a sac with no hernial contents. It was treated via laparoscopic intracorporeal suturing and patient postoperative period was uneventful. Right-sided BH is rare. Regardless of the symptoms surgical treatment should be done to avoid risk of visceral strangulation.

Bochdalek hernia with intrathoracic spleen treated by robotic-assisted mesh repair utilizing indocyanine green contrast media intraoperatively. A case report

Bochdalek hernias are usually diagnosed in newborns. However, they can occur in adults. Few reports exist regarding robotic repair of such hernias. We present a case of a female patient with symptomatic Bochdalek hernia, including the spleen. Patient was successfully treated by robotic-assisted surgical mesh with the use of indocyanine green (ICG). An 80-year-old female patient presented with dyspnea, angina and intermittent abdominal pain. She had loss of appetite and 15-kg weight loss within 3 months. Past medical history was unremarkable. Imaging revealed a left Bochdalek hernia. The patient underwent robotic-assisted surgery; hernia contents included stomach, parts of colon, omentum and remarkably the spleen. Sac was dissected free. Patency of organs was assessed with ICG. Diaphragmatic defect was repaired with mesh. Bochdalek hernias should be surgically repaired. Minimally invasive therapy is safe and effective. Intraoperative ICG use can provide excellent results with favorable clinical outcomes.

Maternal Bochdalek Hernia during Pregnancy: A Systematic Review of Case Reports

Background: Since the first report of a diaphragmatic hernia from Ambroise Paré’s necropsy in 1610, the Bochdalek hernia (BH) of the congenital diaphragmatic hernia (CDH) has been the most common types with high morbidity and mortality in the neonatal period. Due to the nature of the disease, CDH associated with pregnancy is too infrequent to warrant reporting in the literature. Mortality of obstruction or strangulation is mostly due to failure to diagnose symptoms early. Data sources and study selection: A systematic literature search of maternal BH during pregnancy was conducted using the electronic databases (PubMed and EMBASE) from January 1941 to December 2020. Because of the rarity of the disease, this review included all primary studies, including case reports or case series that reported at least one case of maternal BH in pregnant. Searches, paper selection, and data extraction were conducted in duplicate. The analysis was performed narratively regardless of the control groups’ presence due to their rarity. Results: The search retrieved 3450 papers, 94 of which were deemed eligible and led to a total of 43 cases. Results of treatment showed 16 cases in delayed delivery after hernia surgery, 10 cases in simultaneous delivery with hernia surgery, 3 cases in non-surgical treatment, and 14 cases in hernia surgery after delivery. Of 16 cases with delayed delivery after hernia surgery, 13 (81%) cases had emergency surgery and three (19%) cases had surgery after expectant management. Meanwhile, 10 cases underwent simultaneous delivery with hernia surgery, 6 cases (60%) had emergent surgery, and 4 cases (40%) had delayed hernia surgery after expectant management. 3 cases underwent non-surgical treatment. In this review, the maternal death rate and fetal/neonatal loss rate from maternal BH was 5% (2/43) and 16% (7/43), respectively. The preterm birth rate has been reported in 35% (15/43) of maternal BH, resulting from maternal deaths in 13% (2/15) of cases and 6 fetal loss in 40% (6/15) of cases; 44% (19/43) of cases demonstrated signs of bowel obstruction, ischemia, or perforation of strangulated viscera in the operative field, resulting from maternal deaths in 11% (2/19) of cases and fetal-neonatal loss in 21% (4/19) of cases. Conclusion: Early diagnosis and surgical intervention are imperative, as a gangrenous or non-viable bowel resection significantly increases mortality. Therefore, multidisciplinary care should be required in maternal BH during pregnancies that undergo surgically repair, and individualized care allow for optimal results for the mother and fetus.

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 a young adult successfully treated with a laparoscopic approach, a case report

Background

Bochdalek hernias are a rare form of diaphragmatic hernias; they are frequently found in children; however, they have been discovered in completely asymptomatic adults in exceptional situations. Being such a unique pathology, they can be easily confused and misdiagnose, exposing patients to unnecessary treatments.

Case report

Patient is an otherwise healthy 30-year-old patient without past medical history; after vigorous physical activity, a Bochdalek hernia was discovered and successfully treated; on follow-ups, he is doing well without signs of recurrence.

Conclusions

In adults, Bochdalek hernia is an uncommon form of diaphragmatic hernia. As most cases are asymptomatic, a high index of suspicion is needed since diagnosis is challenging. Modern surgical techniques can improve patient recovery and short hospital stay with minimal morbidity or mortality.

Bochdalek diaphragmatic hernia with bowel incarceration

The purpose of this image is to illustrate a Bochdalek hernia diagnosis in a 39-year-old female patient treated on an emergency basis by means of CT-scan and following perioperative observation. Treatment consisted in initial laparoscopy that due to irreducible bowel incarceration was converted into hernia repair surgery through simple suture and thoracic drainage.

Laparoscopic repair of a Bochdalek hernia in an elderly patient: a case report with a review from 1999 to 2019 in Japan

BACKGROUND

A Bochdalek hernia (BH) is a congenital defect of the diaphragm that generally presents in the newborn as life-threatening cardiorespiratory distress. In contrast, the diagnosis of a BH in adults is rare. Surgical repair for adult BH is recommended, but the optimal surgical method remains unclear.

CASE PRESENTATION

A 75-year-old woman presented with progressive dyspnea and back pain, and a diagnosis of BH was made based on chest X-ray and computed tomography. Laparoscopic evaluation revealed a defect in the left posterior attachment of the diaphragm, and a left-sided BH without hernia sac was diagnosed. Parts of the stomach, small intestine, colon, pancreas, and spleen had prolapsed into the left thoracic cavity, without ischemic change, and these herniated organs were reduced to the abdominal cavity. A direct closure of the hernia orifice was possible by the laparoscopic suture technique using a mesh reinforcement. The patient made an uneventful recovery, and no recurrence was found in the 2-year follow-up.

CONCLUSION

A recently published study reviewing detailed cases of repair of adult BH from 1999 to 2019 identified 96 cases, including the present case. The number of reports on laparoscopic and/or thoracoscopic surgery for BH in adults has recently increased, and the approach for repairing BH should be selected carefully on a case-by-case basis.

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.

Standard and Variable Key Anatomical Structures for Safe Surgical Repair of Bochdalek Hernia: A Rare Case Series

Bochdalek hernia (BH) is a developmental defect in the posterolateral diaphragm, allowing herniation of abdominal contents into the thorax causing mechanical compression of the thoracic viscera. This type of hernia is rare in adults, usually asymptomatic and may be diagnosed incidentally in a routine chest X-ray. The aim of the present retrospective study was to highlight the standard and important anatomical structures that are crucial to safe surgical repair of BH during laparotomy and thoracotomy by the placement of mesh graft, along with a short review of the existing evidence. Records from 2005 to 2017 were reviewed to identify the patients with adult BH who underwent mesh repair through thoracotomy or laparotomy and evaluate the possible complications and results. Six patients were operated for adult BH with the above-mentioned techniques. Four underwent laparotomy and two were treated through thoracotomy. Mild fever was reported only in one patient. There was significant improvement in the symptoms of all patients and no recurrence was reported in the subsequent follow-up period. Surgical treatment is strongly indicated for both symptomatic and asymptomatic patients. Surgeons' in-depth knowledge of the anatomy of the diaphragm will ensure better outcomes for the patients.

Minimally invasive management of rare giant Bochdalek hernia in adults

Bochdaleck hernia (BH) is a congenital diaphragmatic hernia that presents after birth with respiratory symptoms and needs surgical treatment in the neonatal period. However, there are some rare cases of adult presentation, which require surgery to avoid complications. BHs can be treated through several approaches, including laparoscopy. Laparoscopic treatment of a giant BH was successfully attempted on a woman affected by multiple myeloma, with severe dyspnoea and dysphagia. Preoperative work-up included chest X ray, CT-scan and MRI. The whole stomach, duodenum, the small bowel, the right and transverse colon, most descending colon and the pancreas were herniated into the thorax. The herniated viscera were totally reduced into the abdominal cavity and the large defect of the left diaphragm repaired with a biosynthetic web scaffold especially designed for diaphragmatic reconstruction. Finally, to avoid a compartment syndrome in an abdomen with not enough room for the reduced viscera, an extended right colectomy with extracorporeal anastomosis was carried out through a mini-laparotomy. At seven-month follow-up, the patient is symptomless and control CT scan showed no hernia recurrence. Laparoscopic repair of large symptomatic adult BHs can be performed successfully with significant clinical improvement, even in difficult cases and fragile patients.

Right-sided Bochdalek hernia containing retroperitoneal fat in the elderly: report of a case

BACKGROUND

Most cases of Bochdalek hernias are diagnosed during the neonatal period and arise on the left side. We report a rare case of a right-sided Bochdalek hernia in an elderly patient.

CASE PRESENTATION

A 72-year-old man presented with chest tightness and nausea. He had no history of thoracic and abdominal trauma. Preoperative CT scan showed a well-circumscribed mass in the right thoracic cavity of 28-cm diameter compressing the right lower lobe. The mass was mostly fat component and seemed to connect with retroperitoneal fat. We made some diagnoses: lipoma, liposarcoma, and diaphragmatic hernia. Surgical resection was performed by thoracotomy so as to resect the mass and repair the defect of the diaphragm. The mass seemed to be retroperitoneal fat which escaped from the hernia orifice. The neck of the mass was separated by a vessel-sealing device immediately above the hernia orifice. The defect of the diaphragm was repaired by direct suturing after completion of resection. Microscopic pathologic examination showed that the mass was maturated fat tissue. Four months postoperatively, there was no evidence of recurrence of the hernia.

CONCLUSIONS

The diagnosis of an adult Bochdalek hernia is often difficult, so it is important to consider the examination carefully and to determine the better surgical procedure.

Repair of a giant diaphragmatic hernia using the dual approach

Bochdalek hernias are diaphragmatic defects seen in pediatrics. About 5–25% of the cases are diagnosed in adulthood, and present with symptoms of chest and abdominal problems. This is a case of an 18-year-old male who presented to the emergency department with epigastric pain, vomiting and dyspnea. Most of the left-sided organs had herniated to the left chest cavity. Immediate surgery was performed. The stomach, spleen and colon were reduced into the abdominal cavity. The diaphragm defect was repaired laparoscopically, but there were limitations due to inadequate space, leading to difficult visualization of the posterior diaphragmatic leaflet. A thoracoscopic approach was taken where we saw the left kidney herniated through the repair site posteriorly. It was reduced and the defect was closed. The early diagnosis of Bochdalek hernias is important to prevent stomach/intestinal strangulation. Laparoscopic surgeons need to be prepared for a thoracic approach in giant congenital diaphragmatic hernias.

Left sided flank pain due to Bochdalek hernia with intrathoracic kidney

A 40 year old woman had undergone surgery as a newborn due to a left sided congenital Bochdalek hernia with the ventricle, spleen, left kidney and adrenal gland located intrathoracically. After three pregnancies, she developed left sided flank pain and dyspnea. A CT scan showed a diaphragmatic hernia with a malrotated intrathoracic placed left kidney with minimal hydronephrosis. The spleen was located caudally in the left iliac fossa; there were no other abnormalities. The patient underwent a thoracotomy with a small resection of the diaphragm in order to replace the kidney in the abdominal cavity and closure of the diaphragmatic defect with a Gore-Tex patch.

[Diaphragmatic hernia in elective thoracic surgery]

AIM

To clarify the indications for reconstructive surgery in patients with diaphragmatic hernia.

MATERIAL AND METHODS

Retrospective trial has included 36 patients with diaphragmatic hernia for the period 1963-2017. There were 23 (63.9%) women and 13 (36.1%) men. The majority of patients (83%) underwent surgery at able-bodied age (18-60 years). 27 (75%) patients had hernia of weak diaphragmatic zones, 9 (25%) - posttraumatic hernia. Diaphragm repair was performed with primary suture. In 2 cases of posttraumatic hernia mesh endoprosthesis was used.

RESULTS

All patients were discharged. Postoperative complications arose in 4 (11.1%) patients, including 2 cases of mesh endoprosthesis deployment. Long-term outcome was followed-up in 15 patients from 6 months to 17 years. Recurrent hernia was absent in all cases.

CONCLUSION

Primary suture is acceptable for diaphragmatic hernia repair. Alloplastic repair is indicated for large defect, when primary suture is impossible or risk of its failure is high.

An Unexpected Adverse Event during Colonoscopy Screening: Bochdalek Hernia

Bochdalek hernia (BH) is defined as herniated abdominal contents appearing throughout the posterolateral segment of the diaphragm. It is usually observed during the prenatal or newborn period. Here, we report a case of an adult patient with herniated omentum and colon due to BH that was discovered during a colonoscopy. A 41-year-old woman was referred to our hospital with severe left chest and abdominal pain that began during a colonoscopy. Her chest radiography showed colonic shadow filling in the lower half of the left thoracic cavity. A computed tomography scan revealed an approximately 6-cm-sized left posterolateral diaphragmatic defect and a herniated omentum in the colon. The patient underwent thoracoscopic surgery, during which, the diaphragmatic defect was closed and herniated omentum was repaired. The patient was discharged without further complications. To the best of our knowledge, this case is the first report of BH in an adult found during a routine colonoscopy screening.
