Uniportal video-assisted thoracoscopy is a safe approach in patients with empyema requiring surgery

Uniportal Video-Assisted Thoracoscopic Surgery for Minor Procedures

INTRODUCTION

Uniportal video-assisted thoracoscopic surgery (uVATS) is becoming popular for major lung resections, even for more complex procedures. The technique initially described for minor procedures seems more difficult to reproduce and has a longer learning curve. This review aims to describe the evolution from multiportal to uVATS and to explore its feasibility and reproducibility by identifying its drawbacks and limitations.

METHODS

Research from PubMed was obtained with the terms [uniportal] AND [surgery] OR [single-port] AND [thoracic surgery] OR [VATS]. Papers concerning pediatric cases and non-English papers were excluded. Individual case reports were also excluded.

DISCUSSION

uVATS seems to be widely adopted and performed for minor procedures. The applicability of uVATS for different indications is discussed, even though practically all thoracic surgical interventions can be performed through a single incision.

CONCLUSIONS

The transition from conventional three-port VATS to uVATS is described in this paper. An increasing number of thoracic surgeons worldwide have adopted this approach, even for major complex anatomical lung resections. Regarding the performance of minor thoracic interventions, we believe this technique is easily reproducible with a short learning curve because the instruments do not cross each other, and intraoperative movements remain intuitive. It is therefore a feasible, safe, and efficacious technique. For these reasons, we believe uVATS should be offered to all patients undergoing minor thoracoscopic procedures.

Ultrasound and Intrapleural Enzymatic Therapy for Complicated Pleural Effusion: A Case Series with a Literature Review

Pleural effusion is the most common manifestation of pleural disease, and chest ultrasound is crucial for diagnostic workup and post-treatment monitoring. Ultrasound helps distinguish the various types of pleural effusion and enables the detection of typical manifestations of empyema, which presents as a complicated, septated effusion. This may benefit from drainage and the use of intrapleural enzyme therapy or may require more invasive approaches, such as medical or surgical thoracoscopy. The mechanism of action of intrapleural enzymatic therapy (IPET) is the activation of plasminogen to plasmin, which breaks down fibrin clots that form septa or the loculation of effusions and promotes their removal. In addition, IPET has anti-inflammatory properties and can modulate the immune response in the pleural space, resulting in reduced pleural inflammation and improved fluid reabsorption. In this article, we briefly review the literature on the efficacy of IPET and describe a case series in which most practical applications of IPET are demonstrated, i.e., as a curative treatment but also as an alternative, propaedeutic, or subsequent treatment to surgery.

Chest wall reconstruction after the Clagett procedure and other types of open-window thoracostomy: a narrative review

Background and Objective

The Clagett procedure is one of the last treatment options for chronic stage pleural empyema. It involves the formation of an open-window in the thoracic wall to allow for continuous drainage and irrigation of the pleural cavity. Once the empyema has been resolved, reconstruction of the chest wall is sometimes challenging. This review aims to identify and summarize the options for reconstructing soft tissue defects of the chest wall following the Clagett procedure and other types of open-window thoracostomy.

Methods

A narrative review was performed of the literature on PubMed, Cochrane Library, ClinicalTrials.gov, and Google Scholar, including all relevant studies published until January 2023.

Key Content and Findings

This review contains an overview of the reconstruction methods and the outcomes of the included studies on reconstructive options after the Clagett procedure and other types of open-window thoracostomy. A subdivision was made based on reconstruction type: pedicled flaps, free flaps, and the use of a vacuum-assisted closure (VAC) device. The advantages of pedicled flaps are reliable vascularization, better tissue match, reduced scarring, and shorter operation time compared to free flaps. However, when pedicled flaps are not available due to damage during previous surgeries or offer insufficient volume to obliterate the cavity, free flaps might be a solution.

Conclusions

In cases where an open-window thoracostomy necessitates chest wall reconstruction, a pedicled flap is the preferred choice, followed by free flaps. Additionally, vacuum-assisted negative pressure wound therapy (VANPWT) techniques have shown potentially promising results (as an adjunct to surgical treatment).

A 2.5-cm single-port video-assisted thoracoscopic surgery for stage III tuberculous empyema: a case report

BACKGROUND

Stage III tuberculous empyema is a common disease of tuberculosis. Traditionally, it has been treated by thoracotomy or video-assisted thoracoscopic surgery with two to four incisions. But conventional surgery has large trauma, large bleeding volume and long recovery time. To our knowledge it is the first report of surgery for stage III tuberculous empyema with a mini single-port approach.

CASE PRESENTATION

A 23-year-old woman admitted to our hospital with complaints of intermittent chest pain for half a year. We got the diagnosis of stage III tuberculous empyema after medical treatment. Considering that the patient was young and unmarried, we decided to perform minimally invasive pleural decortication through a 2.5 cm single port. The operation time was 240 min, and blood loss was 100 ml. The patient recovered well and postoperative pain was mild.

CONCLUSION

This case demonstrates that single-port VATS with a smaller incision for the Stage III tuberculous empyema should be considered in well selected patients.

The uniportal VATS in the treatment of stage II pleural empyema: a safe and effective approach for adults and elderly patients-a single-center experience and literature review

Background

Pleural empyema (PE) is a frequent disease, associated with a high morbidity and mortality. Surgical approach is the standard of care for most patients with II-III stage PE. In the last years, the minimally invasive surgical revolution involved also thoracic surgery allowing the same outcomes in terms of safety and effectiveness combined to better pain management and early discharge. The aim of this study is to demonstrate through our experience on uniportal-video-assisted thoracoscopy (u-VATS) the effectiveness and safety of its approach in treatment of stage II PE. As secondary endpoint, we will evaluate the different pattern of indication of u-VATS in adult and elderly patients with literature review.

Methods

We retrospectively reviewed our prospectively collected database of u-VATS procedures from November 2018 to February 2022, in our regional referral center for Thoracic Surgery of Regione Molise General Surgery Unit of “A. Cardarelli” Hospital, in Campobasso, Molise, Italy.

Results

A total of 29 patients underwent u-VATS for II stage PE. Fifteen (51.72%) patients were younger than 70 years old, identified as “adults,” 14 (48.28%) patients were older than 70 years old, identified as “elderly.” No mortality was found. Mean operative time was 104.68 ± 39.01 min in the total population. The elderly group showed a longer operative time (115 ± 53.15 min) (p = 0.369). Chest tube was removed earlier in adults than in elderly group (5.56 ± 2.06 vs. 10.14 ± 5.58 p = 0.038). The Length of Stay (LOS) was shorter in the adults group (6.44 ± 2.35 vs. 12.29 ± 6.96 p = 0.033). Patients evaluated through Instrumental Activities of Daily Living (IADL) scale returned to normal activities of daily living after surgery.

Conclusion

In addition, the u-VATS approach seems to be safe and effective ensuring a risk reduction of progression to stage III PE with a lower recurrence risk and septic complications also in elderly patients. Further comparative multicenter analysis are advocated to set the role of u-VATS approach in the treatment of PE in adults and elderly patients.

Minimally invasive treatment of an amebic empyema secondary to the transdiaphragmatic rupture of a liver abscess: a case report

Liver abscesses are a common complication in patients with amebiasis. Rarely, these will rupture across the diaphragm causing life-threatening empyemas. Evidence justifies performing surgical debridement or decortication for their treatment, given the better overall performance in comparison to open surgeries. However, no current guideline specifies which is the best approach. This report presents the case of a 39-year-old male with clinical, radiographical and microbiological evidence of an amebic empyema secondary to an amebic liver abscess, who received treatment by video-assisted thoracoscopy. The case description highlights the surgical technique, findings and operative outcomes that could be taken into consideration by other physicians to timely manage similar cases. The latter is especially relevant in underdeveloped and developing countries, where the burden of amebiasis appears to be greater. To the best of the authors’ knowledge, this is the first description of a transdiaphragmatic amebic infection treated in a minimally invasive fashion.

Spectrum of Microorganisms, Antibiotic Resistance Pattern, and Treatment Outcomes Among Patients With Empyema Thoracis: A Descriptive Cross-Sectional Study From the Bahawal Victoria Hospital Bahawalpur, Punjab, Pakistan

Background: This study involves the analysis of spectrum of microorganisms, antibiotic resistance pattern, and treatment outcomes among empyema thoracis patients. This study also analyzes the factors associated with unsuccessful treatment outcome and duration of hospital stay among the patients.

Methods: This was a descriptive, cross-sectional study carried out in the Pulmonology Ward of the Bahawal Victoria hospital, Bahawalpur, Pakistan. All patients with empyema thoracis registered at the study site during the period of 1 year were included in the study. Multivariate regression analysis was used to analyze the factors associated with duration of hospital stay and unsuccessful treatment outcome among the patients.

Results: A total 110 patients were included in the study. Most of the patients (n = 73, 66.4%) were treated with piperacillin/tazobactam alone and in combination with either one or more than one antibiotics as an empiric therapy. Culture was positive in 58 (52.7%) patients and the most commonly identified organisms included, gram-negative Pseudomonas aeruginosa (n = 20; 18.8%) and Klebsiella sp. (n = 11, 10%) followed by same proportion of E. coli. The most commonly identified bacterial isolates showed high level of resistance against antibiotics used as an empiric therapy, while these showed low level of resistance against amoxicillin, clarithromycin, ertapenem, colistin, tigecycline, fosfomycin, rifampicin, and vancomycin. In this study, 82 (74.5%) patients successfully completed the treatment, while 12 (11%) showed no clinical improvement, 5 (4.5%) lost to follow up and 11 (10%) died. In multivariate binary logistic regression analysis, none of the patient attributes were significantly associated with unsuccessful treatment outcome, while in multivariate linear regression analysis, the factors which were significantly associated with duration of hospital stay included; duration of symptoms <2 weeks prior to admission (p = 0.008, beta = −0.247) and resistance to five antibiotic classes (p = 0.02, beta = 0.280).

Conclusion: Close to 25% of the patients did not complete the treatment successfully. Most of the common bacterial isolates showed high level of resistance against the broad-spectrum antibiotics used as an empiric therapy. This is alarming. However, better sensitivity of common bacterial isolates against standardized first line treatment for empyema thoracis is promising.

Pleurectomía parietal y decorticación pulmonar por cirugía torácica asistida por video (VATS) monopuerto versus toracotomía

Introducción. El avance de la cirugía torácica abierta a cirugía torácica asistida por vídeo por tres puertos, y sus posteriores efectos en la recuperación de los pacientes, conllevó al desarrollo de la técnica por un solo puerto, que ha mostrado beneficios en el postoperatorio. El objetivo de este estudio fue comparar los resultados postquirúrgicos de los pacientes sometidos a pleurectomía parietal y decorticación pulmonar toracoscópica asistida por video monopuerto y los obtenidos por toracotomía convencional, en una clínica de cuarto nivel, entre 2016 y 2019. Métodos. Estudio descriptivo, en el que se incluyeron 79 pacientes llevados a pleurectomía parietal y decorticación pulmonar por toracoscopia asistida por vídeo monopuerto y 25 pacientes operados por toracotomía convencional. Se evaluaron variables sociodemográficas, clínicas y postoperatorias. Se utilizaron las pruebas de Chi2 o de Fisher y las pruebas t de Student y Mann Whitney. Resultados. La mediana de edad fue menor en el grupo de pacientes operados por toracotomía convencional (28 años, RIC: 26–48, p=0,0005). No hubo diferencia en los tiempos quirúrgicos. Se encontró menor intensidad del dolor y disminución en los días con tubo de tórax, uso de antibióticos, días de UCI y días de estancia hospitalaria en el grupo de pacientes operados por toracoscopia asistida por vídeo monopuerto (p<0,05). ><0,05). Discusión. Este estudio refuerza la tendencia de mejores resultados postquirúrgicos, menos días de uso del tubo de tórax, uso de antibióticos, necesidad de UCI y días de estancia hospitalaria general con la técnica asistida por vídeo monopuerto comparado con la toracotomía abierta convencional.
