ABSTRACT

The diaphragm is the main breathing muscle and contraction of the diaphragm is vital for ventilation so any disease that interferes with diaphragmatic innervation, contractile muscle function, or mechanical coupling to the chest wall can cause diaphragm dysfunction. Diaphragm dysfunction is associated with dyspnoea, intolerance to exercise, sleep disturbances, hypersomnia, with a potential impact on survival. Diagnosis of diaphragm dysfunction is based on static and dynamic imaging tests (especially ultrasound) and pulmonary function and phrenic nerve stimulation tests. Treatment will depend on the symptoms and causes of the disease. The management of diaphragm dysfunction may include observation in asymptomatic patients with unilateral dysfunction, surgery (i.e., plication of the diaphragm), placement of a diaphragmatic pacemaker or invasive and/or non-invasive mechanical ventilation in symptomatic patients with bilateral paralysis of the diaphragm. This type of patient should be treated in experienced centres. This review aims to provide an overview of the problem, with special emphasis on the diseases that cause diaphragmatic dysfunction and the diagnostic and therapeutic procedures most commonly employed in clinical practice. The ultimate goal is to establish a standard of care for diaphragmatic dysfunction.

ABSTRACT

OBJECTIVE: The aim of the study was to report the safety and efficacy of video-assisted thoracoscopic (VATS) plication of the diaphragm at our institution between 2006 and 2016. METHODS: Adult patients selected on etiology and combination of investigations including plain chest x-ray, computed tomography of chest and abdomen, lung functions in supine and sitting positions, radiological/ultrasonic screening for diaphragmatic movement, and phrenic nerve conduction studies. We incorporated a triportal VATS and Endostitch device for plication, using CO2 insufflation to maximum 12 mm Hg. Bilateral simultaneous plication and high-risk patients were electively admitted to intensive therapy unit postoperatively. RESULTS: Thirty-five patients (24 males) had their diaphragm plicated. The mean age was 56.6 years (range = 23-76 years). The mean body mass index was 32.1 (range = 22.2-45.4). Twenty one were right, 13 left, 2 patients had VATS simultaneous bilateral plication, and 1 had sequential VATS bilateral plication. Paralysis was idiopathic in 17, posttraumatic in 5, postremoval of mediastinal tumor in 4, and postcardiac surgery in 3. All patients presented with lifestyle-limiting dyspnea and orthopnea, three were on nocturnal noninvasive ventilation. Five were diabetic and 16 were smokers. The mean supine forced expiratory volume in the first second was 62.5% of predicted. Twenty two were performed by VATS (63%), three converted to thoracotomy, and 13 were open limited thoracotomy (historic). The mean hospital stay was 4.5 days (range = 1-18, mode 2 days). Intensive therapy unit admission was required in six patients for mechanical ventilation 0 to 3 days. Five patients (14%) had no improvement in symptoms. There were no deaths, no 30-day readmissions, and no long-term neuralgia in this series. CONCLUSIONS: We found minimal access VATS plication of the diaphragm to be feasible and safe, but no firm conclusions should be drawn from our limited resources. We report the feasibility of concomitant bilateral VATS plication of the diaphragm in two adults, and this was not previously reported in the adult population. There is a need for further good quality, prospective studies, and randomized controlled studies evaluating efficacy of VATS diaphragmatic plication.

ABSTRACT

OBJECTIVES: While respiratory distress is accepted as the only indication for diaphragmatic plication surgery, sleep disorders have been underestimated. In this study, we aimed to detect the sleep disorders that accompany diaphragm pathologies. Specifically, the association of obstructive sleep apnea syndrome with diaphragm eventration and diaphragm paralysis was evaluated. METHODS: This study was performed in Süreyyapasa Chest Diseases and Thoracic Surgery Training and Research Hospital between 2014-2016. All patients had symptoms of obstructive sleep apnea (snoring and/or cessation of breath during sleep and/or daytime sleepiness) and underwent diaphragmatic plication via video-assisted mini-thoracotomy. Additionally, all patients underwent pre- and postoperative full-night polysomnography. Pre- and postoperative clinical findings, polysomnography results, Epworth sleepiness scale scores and pulmonary function test results were compared. RESULTS: Twelve patients (7 males) with a mean age of 48 (range, 27-60) years and a mean body mass index of 25 (range, 20-30) kg/m2 were included in the study. Preoperative polysomnography showed obstructive sleep apnea syndrome in 9 of the 12 patients (75%), while 3 of the patients (25%) were regarded as normal. Postoperatively, patient complaints, apnea hypopnea indices, Epworth sleepiness scale scores and pulmonary function test results all demonstrated remarkable improvement. CONCLUSION: All patients suffering from diaphragm pathologies with symptoms should undergo polysomnography, and patients diagnosed with obstructive sleep apnea syndrome should be operated on. In this way, long-term comorbidities of sleep disorders may be prevented.

ABSTRACT

PURPOSE: There is no data comparing different surgical techniques for diaphragmatic re-positioning for hemi-diaphragmatic eventration in adults. Our aim was to verify the potential pros and cons of two major surgical techniques in symptomatic eventration patients. METHODS: Patients undergoing thoracotomy for diaphragmatic elevation repair either by un-opened (accordion placation) or by opened (double-breasted placation) diaphragmatic technique between January 2007 and August 2013 were analyzed retrospectively, and compared in terms of operative outcomes on 12th and 24th months. RESULTS: Forty-two patients underwent accordion (n = 23) or double-breasted (n = 19) plication. Postoperative drainage was significantly increased (215 ± 66 ml vs. 114 ± 48 ml; P = 0.0082) in double-breasted group. Although the corrected diaphragm was radiologically better preserved in this group, this divergence showed no additional effect on postoperative pulmonary functions or the dyspnea score on 12th or 24th months. No complication particularly related to both techniques or recurrence was noted during follow-up of 28 ± 12 months. CONCLUSIONS: Radiological prospect of corrected diaphragm is better preserved with double-breasted plication, but the significant and permanent improvement of respiratory functions was similar. Since the clinical outcome is equivalent, incision of the diaphragm is not essential.

ABSTRACT

Introduction Diaphragmatic eventration is a congenital defect of the muscular portion of a hemidiaphragm that eventually leads to hemidiaphragmatic elevation and dysfunction. The clinical diagnosis of diaphragmatic eventration or diaphragmatic paralysis may be indistinguishable and diaphragmatic plication is the treatment of choice for both conditions. Discussion We review the indications, patient selection, and surgical techniques for diaphragmatic plication. We explain our preferred technique and guide the reader step by step on our approach. Conclusion Minimally invasive diaphragm plication techniques are effective alternatives to open transthoracic plication and result in significant improvement in dyspnea and quality of life in adequately selected patients.

ABSTRACT

Objectives The objective of this study was to analyze the clinical respiratory and spirometric effects of video-assisted minithoracotomy diaphragmatic plication (VAM-T DP) in the treatment of diaphragmatic eventration. Methods A retrospective longitudinal study of 18 patients who underwent a VAM-T DP in our service between February 2005 and July 2011 was performed. Data of patient characteristics, preoperative clinical variables, and postoperative results (3, 6, and 12 months) were collected for statistical analysis using the software package SPSS 13.0 for Windows (Wilcoxon test, Friedman test, and Z-test). Results The main clinical respiratory and spirometric variables improved significantly and remained stable over 1 year. Conclusions VAM-T DP is a viable and safe procedure that improves the spirometry values and offers stable results during the first year. To our knowledge, the present series is the second largest published report in English relating to this procedure in adults.

ABSTRACT

The clinical presentations of diaphragm dysfunctions vary according to etiologies and unilateral or bilateral diseases. Elevation of the hemidiaphragm from peripheral origins, the most frequent situation, requires a surgical treatment only in case of major functional impact. Complete morphological and functional analyses of the neuromuscular chain and respiratory tests allow the best selection of patients to be operated. The surgical procedure may be proposed only when the diaphragm dysfunction is permanent and irreversible. Diaphragm plication for eventration through a short lateral thoracotomy, or sometimes by videothoracoscopy, is the only procedure for retensioning the hemidiaphragm. This leads to a decompression of intrathoracic organs and a repositioning of abdominal organs without effect on the hemidiaphragm active contraction. Morbidity and mortality rates after diaphragm plication are very low, more due to the patient's general condition than to surgery itself. Functional improvements after retensioning for most patients with excellent long-term results validate this procedure for symptomatic patients. In case of bilateral diseases, very few bilateral diaphragm plications have been reported. Some patients with diaphragm paralyses from central origins become permanently dependent on mechanical ventilation whereas their lungs, muscles and nerves are intact. In patients selected by rigorous neuromuscular tests, a phrenic pacing may be proposed to wean them from respirator. Two main indications have been validated: high-level tetraplegia above C3 and congenital alveolar hypoventilation from central origin. After progressive reconditioning of the diaphragm muscles following phrenic pacing at thoracic level, more than 90% of patients can be weaned from respirator within a few weeks. This weaning improves the quality of life with more physiological breathing, restored olfaction, better sleep and better speech. The positive impact of diaphragm stimulation has also been evaluated in other degenerative neurological diseases, particularly the amyotrophic lateral sclerosis. For either central or peripheral diaphragm dysfunctions, a successful surgical treatment lies on a strict preoperative selection of patients.

ABSTRACT

BACKGROUND: Eventration of diaphragm is a congenital condition in which there is absence of muscle fibers in the diaphragm while maintaining all the anatomical attachments normally. Surgical treatment is warranted in symptomatic patients so as to reduce the abnormal ascent of diaphragm. The present study was conducted to analyse the perioperative outcome of thoracotomy in adult patients with diaphragmatic eventration. METHODS: This descriptive case series was carried out in Cardiothoracic Surgery-Unit, Postgraduate Medical Institute, Lady Reading Hospital, Peshawar, Pakistan. Medical records of patients operated upon for eventration from June 2002 to June 2013 were reviewed. Patients of either gender, above 16 years who were operated for symptomatic eventrtaion were included in study. All the demographic data, presenting complaints, baseline and post-postoperative dyspnea grade, forced expiratory volume at 1 second (FEV1) and forced vital capacity (FVC) were recorded on predesigned pro forma and analysed using SPSS-16. RESULTS: A total of 38 adult patients underwent surgery for diaphragmatic eventration over the past 11 years in our unit out of which 29 (76%) were males and rest of 9 (24%) were females. Mean age of patients was 41.6±13.84 years. In 31 (81.5%) patients left side was involved. Majority of patients had a dyspnea grade-3 on presentation. Preoperative dyspnoea score (MRC), FEV1 and FVC values were 2.6±0.73, 63.5±13.3 and 67.2±14.6 respectively. Pre-operative and 6-months follow-up values of dyspnoea grade, FEV1 and FVC values showed statistically significant improvement. CONCLUSION: Our study showed that adult patients with symptomatic unilateral eventration of diaphragm significantly benefit from diaphragmmatic plication.

ABSTRACT

PURPOSE OF REVIEW: This review summarizes the utility and efficacy of different imaging modalities in the diagnosis of diaphragmatic dysfunction. RECENT FINDINGS: Dynamic MRI of the diaphragm has been recently described in the literature as a tool allowing more detailed study of diaphragmatic dysfunction. SUMMARY: The diaphragm is the primary muscle of ventilation. Diaphragmatic dysfunction can be partial or complete, unilateral or bilateral. The diagnosis is difficult to establish at certain times due to diversity of presentations and severity of symptoms. There are several causes of diaphragmatic dysfunction, which adds to the complexity of diagnostic workup. In this review, the basic anatomy and function of the diaphragm and the different pathologic processes that may affect its function will be presented. These processes may originate in the brain, spinal cord, phrenic nerve or the diaphragm itself. Furthermore, this article will review the utility and efficacy of different diagnostic modalities in the diagnosis of diaphragmatic dysfunction. Most of these imaging tools have been well known for several years, including plain chest radiographs, fluoroscopy and ultrasound. An emerging mode is magnetic resonance dynamic imaging, which is another potentially effective way of functional diaphragmatic imaging that is still not part of routine clinical practice.

ABSTRACT

OBJECTIVE: Episodic excessive alcohol consumption (i.e., binge drinking) is now considered to be a major concern in our society. Previous studies have shown that alcohol cues can capture attentional resources in chronic alcoholic populations and that the phenomenon is associated with the development and maintenance of alcoholism. Using event-related potentials (ERPs), we investigated the responses of binge drinkers to alcohol-related pictures. METHODS: Two groups of college students (n=18 in each group) were recruited for the study. One group was composed of binge drinkers and the other of controls. Each student completed a simple visual oddball paradigm in which alcohol-related and non-alcohol-related pictures (positive, neutral or negative) were presented. ERPs were recorded to explore the electrophysiological activity associated with the processing of each cue during the different cognitive steps. RESULTS: Although there were no behavioural differences between the two groups after detection of alcohol- and non-alcohol-related cues, the ERP data indicated that processing of alcohol-related stimuli was modulated by binge drinking: in the binge drinkers, the P100 amplitudes elicited by the alcohol-related pictures were significantly larger than those elicited by the non-alcohol pictures. CONCLUSIONS: The present study provides evidence for an early processing enhancement, indexed by increased P100 amplitude, in binge drinkers when confronted with alcohol cues. SIGNIFICANCE: These findings suggest that higher reactivity to alcohol cues is not a phenomenon limited to adult alcoholics, but that young binge drinkers exhibit signs of prioritizing processing related to alcohol. Prevention intervention for alcohol misuse in young people should consider approaches that address this automatic cue reactivity.

ABSTRACT

Seventeen children with lobar or segmental pneumonia and ispilateral elevation of the diaphragm are described. These children did not differ significantly with respect to clinical and laboratory findings from their counterparts with pneumonia but without elevation of the hemidiaphragm. The elevation was transient and resolved by the time the repeat chest x-ray was taken six to eight weeks later.

ABSTRACT

Diaphragmatic eventration permanently raises all or part of the hemidiaphragm, thus impairing respiratory function by compressing the ipsilateral lung and mediastinum. A 55-year-old woman had cT1N0M0 lung adenocarcinoma in the right lower lobe and diaphragmatic eventration in the left hemithorax. We repaired the eventration to recover respiratory function, then performed a radical lobectomy with mediastinal lymph node dissection. Pathologically, the tumor was a well-differentiated acinar adenocarcinoma (pT1N0M0 stage IA). She was free from cancer and eventration 18 months later. This is the first known report of a lung cancer patient with impaired respiratory function who underwent an intentional radical lobectomy following repair of contralateral diaphragmatic eventration to recover respiratory function.

ABSTRACT

Diaphragmatic plication is technically simple using a conventional operative technique, but it requires a large skin incision and rib injury. We present an alternative technique for thoracoscopic plication of the diaphragm and evaluate the advantages of the procedure. Six patients (five with diaphragmatic eventration and one with diaphragmatic hernia with a sac) ranging in age from 8 to 20 months were treated by this method. Three of the six cases were right-sided, and three were left-sided. The operation was performed under artificial pneumothorax using carbon dioxide gas at 4 mmHg. Three trocars for laparoscopy were inserted at the 4th and 5th intercostal spaces. An adequate operative view was obtained by pressing the diaphragm throughout the operation. The eventrated diaphragm was plicated with several rows of nonabsorbable sutures in the anterolateral-to-posterolateral direction to prevent injury to the main phrenic nerve. A tight diaphragm was confirmed by decompressing the artificial pneumothorax. The technique was successfully performed in all cases, and the patients' postoperative courses were uneventful. During the operation, the hemodynamic effects of carbon dioxide gas at 4 mmHg were minimal. Over a mean follow-up period of 3.1 years (range, 1-6 years), no recurrence of diaphragmatic eventration was seen. Judging from the satisfactory postoperative course, this procedure is suitable for children with all forms of diaphragmatic eventration.

ABSTRACT

Diaphragmatic eventration in the adult may be associated with dyspnoea. Video-assisted thoracoscopic surgery (VATS) techniques have been applied to the plication of diaphragmatic eventration in three adult patients. Symptoms and spirometry improved in all patients. Ventilation and perfusion of the affected lung was also improved.

ABSTRACT

Eventration of the diaphragm is a condition where the muscle is permanently elevated, but retains its continuity and attachments to the costal margin. It is rare, seldom symptomatic, and often requires no treatment. In symptomatic patients, plication of the diaphragm may offer relief of the symptoms.
