SECT Clinical practice guideline on the management of patients with spontaneous pneumothorax

SPLF/SMFU/SRLF/SFAR/SFCTCV Guidelines for the management of patients with primary spontaneous pneumothorax

INTRODUCTION

Primary spontaneous pneumothorax (PSP) is the presence of air in the pleural space, occurring in the absence of trauma and known lung disease. Standardized expert guidelines on PSP are needed due to the variety of diagnostic methods, therapeutic strategies and medical and surgical disciplines involved in its management.

METHODS

Literature review, analysis of the literature according to the GRADE (Grading of Recommendation, Assessment, Development and Evaluation) methodology; proposals for guidelines rated by experts, patients and organizers to reach a consensus. Only expert opinions with strong agreement were selected.

RESULTS

A large PSP is defined as presence of a visible rim along the entire axillary line between the lung margin and the chest wall and ≥ 2 cm at the hilum level on frontal chest X-ray. The therapeutic strategy depends on the clinical presentation: emergency needle aspiration for tension PSP; in the absence of signs of severity: conservative management (small PSP), needle aspiration or chest tube drainage (large PSP). Outpatient treatment is possible if a dedicated outpatient care system is previously organized. Indications, surgical procedures and perioperative analgesia are detailed. Associated measures, including smoking cessation, are described.

CONCLUSION

These guidelines are a step towards PSP treatment and follow-up strategy optimization in France.

Manejo quirúrgico del neumotórax espontáneo primario. Encuesta nacional del Grupo Emergente de Cirugía Torácica de la Sociedad Española de Neumología y Cirugía Torácica (SEPAR)

Introduction

In February 2022, the Emerging Thoracic Surgery Group of the Spanish Society of Pneumology and Thoracic Surgery initiated a multicenter study on the surgical management of primary spontaneous pneumothorax (PSP). As a preliminary step, this survey was developed with the aim of finding out the current situation in our country to specify and direct this project.

Method

A descriptive study was carried out based on the results of this survey launched through the Google Docs® platform. The survey was sent to all active national thoracic surgeons, a total of 319. It consisted of 20 questions including demographic, surgical and follow-up data.

Results

We obtained 124 responses (39% of all specialists and doctors in training in the national territory). The most consistent indications were: homolateral recurrence for 124 (100%), lack of resolution of the episode for 120 (96.7%), risk professions for 104 (84%) and bilateral pneumothorax for 93 (75%). The approach of choice for 100% of respondents was videothoracoscopy. Of these, 96 contemplated pulmonary resection of obvious lesions (77%). Regarding the pleurodesis technique, pleural abrasion was the technique most used by 70 respondents (56.7%) while 49 (40%) performed chemical pleurodesis with talc either alone or in combination with mechanical pleurodesis.

Conclusions

While there is some consistency in some aspects of surgical management of PSP, this survey makes evident the variability in pleurodesis techniques applied among surgeons in our country.

Recommandations formalisées d’experts pour la prise en charge des pneumothorax spontanés primaires

Introduction : Le pneumothorax spontané primaire (PSP) est un épanchement gazeux dans la cavité pleurale, survenant hors traumatisme et pathologie respiratoire connue. Des recommandations formalisées d'experts sur le sujet sont justifiées par les pluralités de moyens diagnostiques, stratégies thérapeutiques et disciplines médicochirurgicales intervenant dans leur prise en charge.

Méthodes : Revue bibliographique, analyse de la littérature selon méthodologie GRADE (Grading of Recommendation Assessment, Development and Evaluation) ; propositions de recommandations cotées par experts, patients et organisateurs pour obtenir un consensus. Seuls les avis d'experts avec accord fort ont été retenus.

Résultats : Un décollement sur toute la hauteur de la ligne axillaire et supérieur ou égal à 2 cm au niveau du hile à la radiographie thoracique de face définit la grande abondance. La stratégie thérapeutique dépend de la présentation clinique : exsufflation en urgence pour PSP suffocant ; en l'absence de signe de gravité : prise en charge conservatrice (faible abondance), exsufflation ou drainage (grande abondance). Le traitement ambulatoire est possible si organisation en amont de la filière. Les indications, procédures chirurgicales et l'analgésie périopératoire sont détaillées. Les mesures associées, notamment le sevrage tabagique, sont décrites.

Conclusion : Ces recommandations sont une étape de l'optimisation des stratégies de traitement et de suivi des PSP en France.

A scoping review of clinical practice guidelines for the diagnosis of primary spontaneous pneumothorax

INTRODUCTION/BACKGROUND

Primary spontaneous pneumothorax (PSP) is characterised by the onset of pneumothorax with no evidence of trauma or associated co-morbidities. Several clinical practice guidelines (CPGs) have been published regarding the management of PSP. Inconsistency in imaging protocols across clinics globally may indicate variability in the recommendations within these guidelines. We aimed to support clinical decision making with an assessment of CPGs regarding PSP diagnosis.

METHODS

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews was utilised. A systematic search of databases Medline, Embase, and Scopus was conducted. Manual searches of the grey literature and guideline-focused databases was undertaken Inclusion criteria included English-language CPGs pertaining to the management of PSP. Publications were independently extracted and critically appraised by two reviewers using the AGREE-II tool. Recommendations were assessed and tabulated.

RESULTS

Eight CPGs met the eligibility criteria. 16 recommendations were identified relating to assessment of medical history, physical examination, assessment of clinical stability, posterior-anterior chest X-ray (CXR) on held inspiration, computed tomography following inconclusive CXR, and ultrasound to complement other imaging modalities.

CONCLUSION

There is universal agreement on the exclusion of expiratory and lateral images in the conventional radiographic series, suggesting that these clinical behaviours may be influenced by local preferences or inhibitors to knowledge translation. This scoping review has summarised the key recommendations of CPGs regarding PSP diagnosis and assessed the methodological quality of the current evidence-base.

Diagnostic and Therapeutic Characteristics in Patients with Pneumotorax Associated with COVID-19 versus Non-COVID-19 Pneumotorax

Introduction: Pneumothorax is a condition that usually occurs in thin, young people, especially in smokers. It is an unusual complication of COVID-19 disease that can be associated with worse results. This disease can occur without pre-existing lung disease or without mechanical ventilation. Materials and Methods: We present a monocentric comparative retrospective study of diagnostic and treatment analysis of two groups of patients diagnosed with COVID-19 and non-COVID-19 pneumothorax. All patients included in this study underwent surgery in a thoracic surgery department. The study was conducted over a period of 18 months. It included 34 patients with COVID-19 pneumothorax and 42 patients with non-COVID-19 pneumothorax. Results: The clinical symptoms were more intense in patients with COVID-19 pneumothorax. We found that the patients with COVID-19 had significantly more respiratory comorbidities. Diagnostic procedures include chest CT exam for both groups. Laboratory findings showed that increasing values for the analyzed data were consistent with the deterioration of the general condition and the appearance of pneumothorax in the COVID-19 group. The therapeutic attitude regarding the non-COVID-19 group was to eliminate the air from the pleural cavity and surgical approach to the lesion that determined the occurrence of pneumothorax. The group of patients with COVID-19 pneumothorax received systemic treatment, and only minimal pleurotomy was performed. The surgical approach did not alter patients’ survival. Conclusions: Careful monitoring of the patient’s clinic and laboratory tests evaluating the degradation of the lung parenchyma, correlated with the imaging examination (chest CT) is mandatory and reduces COVID-19 complications. Early imaging examination starts an effective diagnosis and treatment management. In severe COVID-19 pneumothorax cases, the pneumothorax did not influence the evolution of COVID-19 disease. When we found that the general condition worsened with the rapid progression of dyspnea and the deterioration of the general condition, and we found that it represented the progression or recurrence of pneumothorax.

Secondary spontaneous pneumothorax: a time to re-evaluate management

Spontaneous pneumothorax (SP) is defined as the presence of air in the pleural cavity and remains a significant health problem. Secondary SP (SSP) is associated with underlying lung diseases, such as cystic fibrosis, chronic obstructive pulmonary disease (COPD), and interstitial lung disease (ILD), and is associated with poor outcomes. The current guidelines in the management of SSP have not been updated since the last decade; therefore, new protocols focused on the management of SSP should be evaluated. We present two cases of patients admitted with SSP who were treated conservatively due to haemodynamic stability. In both cases, the pneumothoraces resolved without further complications.

Neumotórax espontáneo y enfisema bulloso bilateral

Introducción. El objetivo de este artículo fue reportar el caso de un paciente con antecedente de enfisema bulloso bilateral que le ocasionó un neumotórax persistente de difícil tratamiento. Caso clínico. Se trata de un paciente de 50 años de edad con diagnóstico de neumotórax asociado con un enfisema bulloso bilateral, en quien estaba contraindicado el tratamiento quirúrgico. El cuadro clínico comenzó con dolor en el hemitórax derecho y disnea, que se fue intensificando hasta el punto de no tolerar el decúbito. En la radiografía de tórax se observó colapso del pulmón derecho con múltiples bulas en ambos pulmones, por lo que se practicó una pleurotomía mínima alta derecha. La evolución del paciente no fue favorable por persistir el neumotórax, lo cual llevó al uso de un tratamiento alternativo. Discusión. En los pacientes con neumotórax persistente por enfisema bulloso bilateral sin indicación quirúrgica, el talco es una alternativa menos invasiva para lograr una sínfisis pleural con buenos resultados, método cuya utilidad se demuestra.
