Management of Diaphragm Paralysis and Eventration.

An elevated diaphragm may be due to eventration or paralysis. Diaphragm elevation is often asymptomatic and found incidentally on imaging. Fluoroscopic testing can be used to differentiate eventration (no paradoxic motion) from paralysis (paradoxic motion). Regardless of etiology, a diaphragm plication is indicated in all symptomatic patients with an elevated diaphragm. Plication can be approached either from a thoracic or abdominal approach, though most thoracic surgeons perform minimally invasive thoracoscopic plication. The goal of plication is to improve lung volumes and decrease paradoxic elevation of the hemidiaphragm. Diaphragm plication is safe, has excellent outcomes, and is associated with symptom improvement.

Clinical evaluation and surgical intervention for diaphragmatic eventration mimicking peritoneopericardial hernia in a cat.

A 2-year-old spayed female British Shorthair cat presented with an increased frequency and duration of cough since infant period. Based on radiographic, ultrasonographic, and computed tomography findings, peritoneopericardial diaphragmatic hernia was considered so that repair surgery was planned. During celiotomy, lax diaphragm was identified instead of defect. Transabdominal diaphragmatic plication was performed to resolve lax diaphragm and to prevent recurrence by overlapping relatively normal part of diaphragm. Diagnosed with diaphragmatic eventration postoperatively, the cat showed improvement in clinical signs and imaging results. Transabdominal diaphragmatic plication is a suitable treatment; the patient maintained normally during a 14-month follow-up period.

Laparoscopic approach in the management of diaphragmatic eventration in adults: gastrointestinal surgical perspective.

The current literature is poor with studies handling the role of laparoscopy in managing diaphragmatic eventration (DE). Herein, we describe our experience regarding the role of laparoscopy in managing DE patients presenting mainly with gastrointestinal symptoms. We retrospectively reviewed the data of 20 patients who underwent laparoscopic diaphragmatic plication between January 2010 and December 2018. Postoperative outcomes and quality of life were assessed. Most DEs were left sided (95%). Laparoscopic diaphragmatic plication was possible in all patients, along with correcting all associated gastrointestinal and diaphragmatic problems. The former included gastric volvulus (60%), reflux esophagitis (25%), cholelithiasis (5%), and pyloric obstruction (5%), while the latter included diaphragmatic and hiatus hernia (10% and 15%, respectively).The average operative time was 142 min. All patients had a regular (reviewer #1) postoperative course except for one who developed hydro-pneumothorax. At a median follow-up of 48 months, midterm outcomes were satisfactory, with an improvement (reviewer #1) in gastrointestinal symptoms. Three patients (reviewer #1) developed radiological recurrence without significant clinical symptoms. Patient's quality of life, including all parameters, significantly improved after the laparoscopic procedure compared to the preoperative values. Laparoscopic approach is safe and effective for managing adult diaphragmatic eventration (reviewer #1).

Comparison of short-term outcomes of video-assisted thoracoscopic (VATS) plication of diaphragmatic eventration - a six-year prospective cohort study.

Diaphragmatic eventration is one of the rarest conditions characterized by elevation of the hemidiaphragm while maintaining its normal attachments. In recent years, video-assisted thoracoscopic surgery (VATS) has gained popularity for diaphragmatic surgery. In this study, we share our experience over six years with VATS plication of diaphragmatic eventration. We conducted a prospective study at our institute for six years from April 2016 to March 2021, which included 37 symptomatic patients with diaphragmatic eventration. The sample size reported in this study is one of the largest to date for VATS diaphragmatic plication. Of these, 18 patients underwent combined stapler and suture plication, and 19 patients underwent single modality approach (10-stapled resection, 9-suture alone plication). All patients were followed-up for a minimum of 2 years. Comparative analysis of the combined approach and the single modality approach was performed. The mean operative time was significantly longer with the combined approach (p value < 0.01). However, there was no difference in postoperative pain (p value = 0.50), analgesia requirement (p value = 0.72), or pleural drainage (p value = 0.32) between the two approaches. Although not statistically significant, the combined approach had fewer post-operative complications (p value = 0.32). Besides, the Single modality approach resulted in one recurrence (p value = 0.32) and one mortality (p value = 0.32). VATS diaphragmatic plication using staplers and/or sutures is safe and efficacious in the management of diaphragmatic eventration. Surgeons should consider using both staplers and sutures whenever possible, rather than selecting one over the other.

Video-assisted thoracoscopic diaphragm oblique resection simplified with an endostapler for diaphragm eventration.

Diaphragm plication has recently become a standard operation for diaphragm eventration. The surgical experience for the patient has improved with the development of minimally invasive operations, but the operator's convenience has not improved significantly. We performed video-assisted thoracoscopic surgery for a diaphragm oblique resection using endostaplers in 10 patients. The total operation time was 39.5 minutes; all patients' symptoms disappeared postoperatively. This presentation will help more thoracic surgeons simplify this operation on the diaphragm.

First case of bilateral diaphragm eventration successfully repaired through an abdominal approach following lung transplantation.

A 61-year-old male patient with bilateral lung transplantation was admitted to the outpatient clinic with increasing respiratory distress for a month. Bilateral diaphragm eventration was observed in his examinations. Bilateral diaphragm plication was successfully performed abdominally in the patient who had a complaint despite supportive treatment. The respiratory capacity of the patient returned to normal. The abdominal approach may be a good alternative option in cases where intrathoracic surgery cannot be performed due to adhesions in patients with eventration after lung transplantation. KEY WORDS: Acquired eventration, Diaphragm, Lung transplantation.

Right-side diaphragmatic eventration with atrial septa defect and cleft palate in an infant: a case report.

BACKGROUND: Congenital right-side diaphragmatic eventration with atrial septal defect and cleft palate is a rare congenital anomaly. CASE PRESENTATION: We present a rare case of congenital right-sided diaphragmatic eventration along with atrial septal defect, cleft palate, pneumonia, and undernutrition in a 3-month-old Asian and Afghan girl. The clinical features were observed in the third month of life, and the diagnosis of these anomalies was established by the patient's history, physical examination, chest X-ray, thoracic computed tomography, and echocardiography. Her condition was good after supportive treatment. Since the index case of diaphragmatic eventration was associated with congenital heart disease, cleft palate, and parental consanguinity, a genetic basis may have played an important role in the pathogenesis of this anomaly. CONCLUSION: Eventration of the diaphragm may be diagnosed in early infancy, and genetic factors may contribute to its pathogenesis.

Challenge of a therapeutic sequence: rare case of heart failure in mitral valvular disease intensified by an extreme mediastinal shift from major diaphragmatic eventration.

Extreme mediastinal shift due to major diaphragm eventration is complex when mitral-valve repair is required. We report the case of a 59-year-old woman with diaphragmatic eventration who had 2 recent episodes of heart failure due to arrythmia associated with severe mitral-valve regurgitation (regurgitant orifice area 47 mm2). Forced expiratory flow-volume in the first second and vital capacity (VC) were at 32% and 33%, respectively,decreasing to 20% and 30% when she was in a supine position. We found it impossible to repair the valve first because of the extreme mediastinal shift and respiratory dysfunction. Therefore, we decided to perform diaphragm plication first followed 3 months later by mitral valve repair. Six months after the cardiac operation, the patient showed significant clinical improvement. Forced expiratory flow-volume in the first second and vital capacity increased to 58% and 55%, respectively. The decision to perform the thoracic operation first, followed by the cardiac operation, was the key to improving the patient's respiratory function and to medializing the heart to safely support cardiac surgery.

High insertion of the right diaphragm complicated with congenital diaphragmatic hernia: A case report of rare thoracoscopic findings.

We encountered a case of high insertion of the right diaphragm complicated with congenital diaphragmatic hernia that was diagnosed based on thoracoscopic findings. A full-term male baby was suspected of having right congenital diaphragmatic hernia or diaphragmatic eventration on postnatal imaging. He only had episodes of mild but prolonged symptoms following upper respiratory tract infection and his course was otherwise uneventful during outpatient monitoring. At 1 year old, the elevated liver volume remained large, which might eventually interfere with his lung growth, so thoracoscopic exploration was planned. Thoracoscopy revealed liver prolapse from a diaphragmatic defect. In addition, the anterior to lateral inserted part of the diaphragm was high, with the anterior part reaching the fourth rib. We repaired only the diaphragmatic defect without repositioning the diaphragm, and the postoperative course was uneventful. High insertion of the diaphragm should be considered as a differential diagnosis of congenital diaphragmatic eventration.

An Infant with Congenital Diaphragmatic Eventration with Dextrocardia: A Case Report.

Diaphragmatic eventration is a rare condition, and its association with dextrocardia is even a rarer clinical entity. Patients are usually asymptomatic, but the typical features include rapid breathing and recurrent respiratory infections. Here we present a rare case of a seven months old infant, who presented with cough, noisy breathing and chest retraction. The patient was diagnosed to have dextrocardia with diaphragmatic eventration with pneumonia by chest imaging and was treated in coordination with the medical team for underlying pneumonia. Afterwards, plication of the diaphragm was done through the trans-abdominal approach and the symptoms gradually improved postoperatively. For dextrocardia, since there were no structural abnormalities, the patient was kept in regular follow-up in the pediatric cardiology unit. Though most patients are asymptomatic, diaphragmatic eventration increases the risk of recurrent chest infection and hampers the quality of life of the patient, so timely diagnosis and intervention will greatly improve their quality of life. Keywords: dextrocardia; diaphragm; diaphragmatic eventration.

Robotic-assisted diaphragmatic plication: Improving safety and effectiveness in the treatment of diaphragmatic paralysis.

BACKGROUND: Diaphragmatic plication can be performed with various surgical approaches. The aim of this study was to assess the safety and effectiveness of robotic-assisted plication. METHODS: We retrospectively reviewed consecutive patients who underwent diaphragmatic plication from 2017 to 2021. RESULTS: Eighteen patients underwent 20 operations, 11 of which were performed with robotic-assisted thoracoscopic surgery (RATS) and 9 with open transthoracic approach. RATS was associated with shorter operating time (80 vs. 120 min; p = 0.04), less blood loss (20 vs. 100 ml; p = 0.01), shorter chest-drain duration (1 vs. 3 days; p = 0.01), and shorter length of stay (3 vs. 7 days; p = 0.04). The median grade in the Medical Research Council dyspnoea scale improved from four to two in both groups. CONCLUSIONS: Robotic-assisted diaphragmatic plication is a safe procedure that can significantly improve dyspnoea and is associated with shorter hospitalisation compared to open approach.

[Thoracoscopic Plication for Congenital Diaphragmatic Eventration in an Adult].

Thoracoscopic plication for congenital diaphragmatic eventration in an adult. Diaphragmatic eventration is known to be abnormal elevation of diaphragm and congenital causes are due to abnormal diaphragm muscle development. Here we report surgical treatment of congenital diaphragmatic eventration. A 45-year-old woman who complained of cough was admitted to our hospital. She had history of cough and was diagnosed as diaphragmatic eventration in childhood. Chest X-ray showed elevated left hemidiaphragm with a bowel gas underneath. Under the diagnosis of congenital eventration of left hemidiaphragm, plication of the left diaphragm by video-assisted thoracoscopic surgery (VATS) was performed. One month after surgery, severe cough disappeared completely.

Comparative Study of Thoracoscopic and Modified Small Incision Repair for Congenital Diaphragmatic Eventration in Children.

Background: Thoracoscopic diaphragmatic plication has gained popularity in the treatment of congenital diaphragmatic eventration (CDE), but the therapeutic effect and prognosis have rarely been compared with nonendoscopic surgery. Materials and Methods: The medical records of 77 children who had received treatment for CDE in our institution from September 2006 to January 2019 were retrospectively analyzed. According to the repair approach, the children were divided into a thoracoscopic plication group and a modified small incision plication group. The perioperative characteristics and follow-up details after diaphragm plication were compared between the two groups. Results: Among 77 children with CDE, 44 cases were in the thoracoscopic plication group and 33 cases were in the modified small incision plication group. All the cases of CDE were unilateral, with 13 cases on the left side and 64 cases on the right side. There were no differences in the preoperative characteristics between the two groups. The modified small incision plication group had a higher bleeding volume (P = .000) and a greater proportion of patients needing chest drainage (P = .000), whereas the differences in the total and postoperative hospital stays (P = .088, P = .247, respectively) did not significantly differ between the two groups. There were no differences in postoperative improvement in the location of the diaphragm between the two groups or between the right and left lesions (P = .438, P = .677, respectively). The total follow-up time was 2-11 years. No recurrence was reported during this period in either of the groups, but the incidence of postoperative thoracic deformities was higher in the modified small incision plication group (P = .013). Conclusions: Compared with the modified small incision plication, thoracoscopic plication has the advantages of smaller blood loss, a low percentage of intrathoracic drainage tube usage, and no occurrence of thoracic deformities.

Laparoscopic management of gastric volvulus, diaphragmatic eventration and wandering spleen in a child.

Gastric volvulus (GV) and wandering spleen (WS) associated with eventration of diaphragm share a common pathological cause of absence or laxity of intraperitoneal ligaments. We herein report a rare case of a 13-year-old child presenting with an acute GV, WS, diaphragmatic eventration and an ectopic ascended kidney managed with a laparoscopic approach.

The feasibility and safety of same-day surgery for diaphragmatic eventration by minithoracotomy in children.

PURPOSE: The diaphragmatic plication procedure by thoracoscopy has gradually become standard treatment for diaphragmatic eventration (DE). However, thoracoscopic diaphragmatic plication is difficult to manipulate and the surgical learning curve is long. This study aimed to demonstrate the feasibility and safety of same-day surgery for DE by minithoracotomy in children. METHODS: From December 2017 to December 2019, we included 22 patients who underwent diaphragmatic plication of DE in the Department of Pediatric Thoracic Surgery at the Guangzhou Women and Children's Medical Center. A total of 10 patients underwent diaphragmatic plication by minithoracotomy and 12 patients underwent thoracoscopic plication. The perioperative condition and postoperative follow-up were evaluated, respectively. RESULTS: The age, sex, and weight were no different in the minithoracotomy group versus the thoracoscopy group (P > 0.05). The intraoperative time, blood loss volume, and postoperative hospital stay of the minithoracotomy group were significantly less than that of the thoracoscopy group (31.10 ± 4.70 min vs. 72.08 ± 22.8 min; 1.20 ± 0.42 ml vs. 2.58 ± 1.67 ml; and 1.00 ± 0.00 days vs. 6.00 ± 2.95 days, respectively, all P < 0.05). The eventration levels in these two groups were significantly different in the perioperative and postoperative periods as detected by chest X-ray. No chest tubes were inserted and no recurrence of DE occurred in the thoracoscopy group through the postoperative follow-up of at least 6 months. CONCLUSION: Same-day surgery by minithoracotomy as a treatment for DE was feasible and safe with less operative time, less blood loss, and low recurrence. Same-day surgery for DE was attributed to a quick recovery. More prospective studies are necessary to further explore the consequences of same-day surgery for DE by minithoracotomy.

Three-dimensional reconstruction model in the diagnosis of Morgagni's hernia.

Morgagni's hernia (MH) can be diagnosed by different utilities, but all these methods are not always 100% accurate. Three-dimensional (3D) reconstruction model could be helpful in better understanding the important anatomical structures. We report a case of MH who was once misdiagnosed as diaphragmatic eventration at the other institution and we offered laparoscopic repair according to the 3D reconstruction model. Our case highlights that 3D reconstruction model could be a useful supplementary tool in the diagnosis and preoperative assessment for patients with MH especially when it is confused in diagnosis in clinical practice.

Diaphragmatic plication for diaphragmatic eventration caused by chronic constipation: a case report.

Diaphragmatic eventration in an adult patient is a rare condition. We describe a case of an elderly patient with hemidiaphragm dysfunction caused due to chronic constipation. A 67-year-old woman with a medical history of descending colon cancer that was treated 24 years before undergoing partial colectomy was admitted to our hospital with complaints of progressive shortness of breath and dyspnea on exertion for the past few months. She had no past history of any trauma. The patient had previously been suffering from chronic constipation after surgery. Physical examination revealed distension and incisional hernia of the abdomen. Chest X-ray demonstrated the high position of the left dome of the diaphragm with the megacolon gas. Chest and abdominal computed tomographic scans disclosed left diaphragmatic displacement containing the stomach and megacolon and abdominal incisional hernia. We performed open laparotomy, repair of abdominal incisional hernia using mesh, and diaphragmatic plication with nonabsorbable polyester suture and pledgets. Postoperative imaging confirmed the significant improvement of the patient's left lung space and clinical resolution of her respiratory symptoms. We describe the case of a patient with diaphragmatic eventration that was caused due to chronic constipation who underwent successful surgical repair.

Reinforcing the vascular disruption theory of the genesis of Poland's syndrome: a rare association of diaphragmatic eventration in a preterm infant with severe musculoskeletal defects.

A preterm female infant was admitted at birth with respiratory distress. On examination, she had an asymmetric right chest wall and ipsilateral small hand. Air entry was reduced over the right chest. A clinical diagnosis of Poland's syndrome was made based on the hypoplasia of the right pectoral muscles, absent nipple, deformed ribs and symbrachydactyly of the ipsilateral hand. Chest X-ray suggested and ultrasound confirmed eventration of the right hemidiaphragm. 'Subclavian artery supply disruption sequence' (SASDS) theory by Bavnick and Weaver remains the most accepted pathogenic mechanism in Poland's syndrome. This case reinforces SASDS theory associated with the genesis of Poland's syndrome that relates to the pathogenicity of vascular disruption of subclavian artery, characteristics of which are unilateral pectoral defects, symbrachydactyly and eventration of the diaphragm. At 2 months, she underwent diaphragm plication. She is under review by our multidisciplinary surgical team for reconstruction of the chest deformity.

Diaphragmatic Pathology in Children: Not Always an Easy Diagnosis.

ABSTRACT: We present a rare case of a 10-year-old boy with a right diaphragmatic eventration (DE), an uncommon pathology in children. The case highlights the importance of making a correct differential diagnosis between an acquired diaphragmatic hernia and a DE, two uncommon diaphragmatic pathologies. Differential diagnosis of these two entities can usually be made based on radiological findings, by identifying the continuity or the lack of continuity of the diaphragm, but sometimes, especially when on the right side, like in our case, they can be very difficult to differentiate by imaging. Diaphragmatic eventration is an abnormal elevation of an intact diaphragm that maintains its continuity and its attachments to the costal wall. Diaphragmatic hernia occurs when abdominal organs move into the chest through a defect in the diaphragm. Diaphragmatic hernia is generally symptomatic and always a medical emergency and requires urgent surgery, whereas DE is generally asymptomatic, has a better prognosis, and can be treated conservatively.As the treatment, the surgical approach, and the prognosis of these two entities are very different, a correct differential diagnosis is very important.
