Medical thoracoscopy removal of a self-expandable metallic stent migration into pleural cavity

Beyond diagnosis: a narrative review of the evolving therapeutic role of medical thoracoscopy in the management of pleural diseases

Background and Objective

Medical thoracoscopy (MT) is an endoscopic technique performed by interventional pulmonologists with a favorable safety profile and few contraindications, providing diagnostic and therapeutic intervention in a single sitting. This narrative review was designed to summarize the therapeutic role of MT based on the latest results from the available literature.

Methods

Pertinent literature published in English, relative to human studies, between 2010-2022 was searched in Medline/PubMed and Cochrane databases. Publications regarded as relevant were considered for inclusion in this review; additional references were added based on the authors' knowledge and judgment. The review considered population studies, meta-analyses, case series, and case reports.

Key Content and Findings

MT has mostly been described and is currently used globally in the diagnostic approach to exudative pleural effusion of undetermined origin. Carefully evaluating the literature, it is clear that there is initial evidence to support the use of MT in the therapeutic approach of malignant pleural effusion, pneumothorax, empyema, and less frequently hemothorax and foreign body retrieval.

Conclusions

MT is an effective procedure for treating the clinical entities presented in this document; it must be carried out in selected patients, managed in centers with high procedural expertise. Further evidence is needed to assess the optimal indications and appropriate patients' profiles for therapeutic MT. The endpoints of length of hospital stay, surgical referral, complications and mortality will have to be considered in future studies to validate it as a therapeutic intervention to be applied globally.

The role of VATS in the removal of intrathoracic foreign bodies - a systematic review

Introduction

To date, no systematic review or meta-analysis study has been conducted regarding the use of video-assisted thoracoscopic surgery (VATS) in the removal of intrathoracic foreign bodies (FB). This systematic review aims to evaluate the feasibility of VATS in the removal of intrathoracic FBs.

Methods

PubMed/MEDLINE, CINAHL, Web of Science, EMBASE, and Cochrane Library databases were systematically searched to identify reports published up to April 1, 2022.

Results

The initial systematic search revealed a total of 208 papers, of which only 54 studies reporting 71 cases were included in this systematic review. Among the patients, 46 (64.8%) were male, 22 (31%) were female, and 3 (4.2%) were unknown. The mean age was 34.5 ± 24.3 years (1 day to 98 years). The patients were of 3 etiologic groups: iatrogenic (31, 43.7%), traumatic (28, 39.4%), and accidental (9, 12.7%). Most of the patients were emergency cases (27, 38%). The most frequently used imaging modalities to diagnose these foreign bodies were X-ray (46, 64.8%), followed by computed tomography (44, 62%), and ultrasonography (16, 22.5%). About 43% of all the foreign bodies were therapeutic equipment. The pleural cavity had the highest involvement (36.8%), followed by the lung parenchyma (14.6%) and thoracic cavity (13.2%). Regardless of the number of access ports, all the patients had a good clinical outcome.

Conclusion

VATS is a safe and effective method for the removal of intrathoracic FBs from various thoracic sites that are associated with a good clinical outcome - in both elective and emergency cases.
