Complications of indwelling pleural catheter use and their management

Clinical outcomes of caregiver-led indwelling pleural catheter care and drainage at a Singapore tertiary referral hospital

Background

Indwelling pleural catheters (IPCs) are an established first-line treatment option for symptomatic malignant pleural effusions (MPEs). However, community nursing support for IPC care and drainage is not available in many healthcare systems. In this study, we sought to evaluate IPC outcomes and complication rates in patients for whom IPC care and home drainage are performed by family members and caregivers.

Methods

Patients who underwent IPC insertions between January 2017 to December 2022 were included in this observational cohort study. Caregiver training were provided to all patients and appointed caregivers by pleural specialist nurse. All patients were assessed at regular intervals every 1 to 2 months, until death or IPC removal. Clinical outcomes and adverse events were recorded prospectively.

Results

We evaluated 140 patients with a median age of 68 years [interquartile range (IQR): 61-73 years]. MPE was the underlying etiology in 137 patients (97.9%). The most common causes of MPE were lung cancer (42.9%) and breast cancer (22.1%). The median duration of IPC placement was 64 (IQR: 36-120) days. About a third of patients (35.0%) had spontaneous pleurodesis allowing for removal of the IPC, with this occurring at a median of 78 (IQR: 52-144) days. The median length of survival from the time of IPC insertion was 102 (IQR: 41-308) days. IPC related complications occurred in 38 (27.1%) patients. Catheter malfunction, most commonly a non-draining IPC due to catheter blockage, occurred in 27 (19.3%) of patients, and 14 (10.0%) patients developed infective complications. Nine (6.4%) patients required hospitalisation for IPC-related complications. There were no bleeding complications or procedure-related deaths.

Conclusions

In healthcare systems without available community nursing services, IPCs remain a valuable treatment option for patients with symptomatic MPEs. Comparable clinical outcomes and safety profiles can be achieved even for patients where IPC care and drainage are primarily led by caregivers or family members, in the presence of appropriate support and caregiver training provided by a pleural service.

Impact of educational videos and user guide on indwelling pleural catheter caregiver training and unplanned healthcare encounters

BACKGROUND

Indwelling pleural catheters (IPCs) are an effective first line option for the management of symptomatic malignant pleural effusions. However, patients with IPCs often require unplanned healthcare encounters (UHEs) due to complications or concerns with IPC care and drainage.

LOCAL PROBLEM

There is a lack of readily accessible IPC-specific educational material to support caregiver training (CGT). As IPC care and drainage are performed primarily by patients and caregivers in our country due to the lack of community nursing support, ineffective CGT may lead to increased UHEs due to caregiver knowledge gaps or poor confidence in managing and caring for IPCs.

AIMS

We aim to reduce the number of IPC-related UHEs.

METHODS AND INTERVENTIONS

We used a 5-why diagram and identified a lack of appropriate educational material as a key factor contributing to repeated UHEs. We therefore produced and employed IPC-specific educational videos and user guides, using a 'Plan-Do-Study-Act' approach, into our CGT programme. Patient demographics and clinical outcomes were collected prospectively for 166 consecutive patients with IPC insertions, with 72 patients in the preintervention group and 94 in the postintervention group. Survey questionnaires addressing caregiver competency and confidence were also administered after CGT using these tools.

RESULTS

There was a significant decrease in the proportion of patients who had ≥2 (8.5% vs 40.9%, p<0.001) or ≥3 UHEs (3.2% vs 31.8%, p<0.001) in the intervention group. There was also a higher caregiver competency score achieved in the intervention group (7 (IQR: 7-7) vs 5 (IQR: 5-7), p<0.001). There was no difference in overall complication and IPC-related infection rates between groups.

CONCLUSION

IPC-specific educational videos and resources, which are readily accessible and easily implemented into CGT programmes, reduce UHEs due to IPC-related issues and may improve caregiver knowledge and competency in IPC care and drainage.

Pro: indwelling pleural catheters cause harm to patients

Malignant pleural effusions (MPE) tend to recur and require definitive treatment with either chest drain and talc pleurodesis or indwelling pleural catheters (IPCs), which offer similar symptomatic benefits. In recent years, IPCs have become popular due to the presumed convenience of an outpatient procedure followed by home drainage leading to a misconception of IPCs being an ideal treatment for MPE. However, IPCs predispose the patient to multiple complications and have significant physical and psychological implications that are under-recognised. Patients require additional clinical reviews, hospital admissions and treatment for these complications related to IPCs. Additionally, there is a huge psychological impact of living with a home catheter that is a constant reminder of their cancer and this has been shown to affect quality of life negatively. Hence, IPCs should not be considered the "ideal" treatment for MPE management and clinicians should reflect the equipoise of the evidence for the benefits and accurately reflect the adverse effects of IPCs in their discussions with patients to facilitate informed decision making.

Exploring the efficacy and advancements of medical pleurodesis: a comprehensive review of current research

This narrative review aims to provide an overview of medical pleurodesis techniques, and their indications and potential adverse effects. Pleurodesis is a procedure performed with the aim of obliterating the pleural space. It has indications in the management of both malignant and benign pleural effusions and pneumothorax. Various nonsurgical techniques exist to perform pleurodesis. The scope of this work is to review the different nonsurgical techniques and their indications. This narrative review was performed checking scientific databases for medical literature, focusing especially on the data derived from randomised controlled trials. Pleurodesis is an effective method to manage pleural effusions and pneumothorax, and minimally invasive techniques are now frequently used with good results. Further research is needed to assess the efficacy of new treatments and the possibility of using different techniques in association.

Iatrogenically Acquired Mycobacterium abscessus Infection in an Indwelling Intercostal Drainage In Situ in a Patient With Alcoholic Liver Disease and Bilateral Hepatic Hydrothorax: A Report of a Rare Case

A 47-year-old male, a known case of alcoholic chronic liver disease with portal hypertension, presented with complaints of abdominal distension and shortness of breath. A provisional diagnosis of ethanol-related compensated chronic liver disease (CLD) with portal hypertension and splenomegaly, gross ascites with bilateral hepatic hydrothorax was made. The left-sided pleural effusion subsided after three pleural taps, but the right-sided effusion kept refilling even after four to five days of repeated therapeutic taps, so a pigtail catheter was left in situ. The pleural fluid was sent for culture which did not grow any pathogenic organisms. Cartridge-based nucleic acid amplification tests where Mycobacterium tuberculosis complex (MTBC) was not detected, Ziehl-Neelsen staining was done in which acid-fast bacilli were not seen, and cytology was done where no malignant cells were seen. The patient was discharged with the pigtail in situ on the right side and, after 20 days, the patient again presented with shortness of breath, and imaging revealed moderate right-side pleural effusion. Draining of pleural fluid was done and sent for investigation which again revealed no infective etiology. The patient was admitted to the hospital for one month as the right-sided effusion did not resolve. Suddenly, the patient developed shortness of breath, and a chest X-ray was done, which showed pigtail blockage; pigtail flushing was done, and the bag was drained. The patient was empirically started on IV meropenem 500 mg TID, IV teicoplanin 400 mg BD, and inj polymyxin B 500,000 IU IV BD. The pleural fluid was sent continuously for investigation for the first two months which again did not reveal any infective etiology. After two months of pigtail in situ, the pleural fluid was sent for CBNAAT where MTBC was not detected, and ZN stain showed smooth acid-fast bacilli. The sample was cultured, and it grew acid-fast bacilli in 72 hours on blood agar, MacConkey agar, and Lowenstein-Jensen media. A line probe assay done from the isolate revealed it to be Mycobacterium abscessus subsp. abscessus which was resistant to macrolides and sensitive to aminoglycosides. Mycobacterium abscessus subsp. abscessus was isolated from repeated cultures of pleural fluid, and the patient was advised on a combination treatment of amikacin, tigecycline, and imipenem. The patient was discharged with the indwelling pigtail with the advised treatment; unfortunately, we lost patient follow-up as the patient never returned to us.

Australasian Malignant PLeural Effusion (AMPLE)-4 trial: study protocol for a multi-centre randomised trial of topical antibiotics prophylaxis for infections of indwelling pleural catheters

BACKGROUND

Malignant pleural effusion (MPE) is a debilitating condition as it commonly causes disabling breathlessness and impairs quality of life (QoL). Indwelling pleural catheter (IPC) offers an effective alternative for the management of MPE. However, IPC-related infections remain a significant concern and there are currently no long-term strategies for their prevention. The Australasian Malignant PLeural Effusion (AMPLE)-4 trial is a multicentre randomised trial that evaluates the use of topical mupirocin prophylaxis (vs no mupirocin) to reduce catheter-related infections in patients with MPE treated with an IPC.

METHODS

A pragmatic, multi-centre, open-labelled, randomised trial. Eligible patients with MPE and an IPC will be randomised 1:1 to either regular topical mupirocin prophylaxis or no mupirocin (standard care). For the interventional arm, topical mupirocin will be applied around the IPC exit-site after each drainage, at least twice weekly. Weekly follow-up via phone calls or in person will be conducted for up to 6 months. The primary outcome is the percentage of patients who develop an IPC-related (pleural, skin, or tract) infection between the time of catheter insertion and end of follow-up period. Secondary outcomes include analyses of infection (types and episodes), hospitalisation days, health economics, adverse events, and survival. Subject to interim analyses, the trial will recruit up to 418 participants.

DISCUSSION

Results from this trial will determine the efficacy of mupirocin prophylaxis in patients who require IPC for MPE. It will provide data on infection rates, microbiology, and potentially infection pathways associated with IPC-related infections.

ETHICS AND DISSEMINATION

Sir Charles Gairdner and Osborne Park Health Care Group Human Research Ethics Committee has approved the study (RGS0000005920). Results will be published in peer-reviewed journals and presented at scientific conferences.

Outcomes of Pleural Space Infections in Patients With Indwelling Pleural Catheters for Active Malignancies

BACKGROUND

Pleural infections related to indwelling pleural catheters (IPCs) are an uncommon clinical problem. However, management decisions can be complex for patients with active malignancies due to their comorbidities and limited life expectancies. There are limited studies on the management of IPC-related infections, including whether to remove the IPC or use intrapleural fibrinolytics.

METHODS

We conducted a retrospective cohort study of patients with active malignancies and IPC-related empyemas at our institution between January 1, 2005 and May 31, 2021. The primary outcome was to evaluate clinical outcomes in patients with malignant pleural effusions and IPC-related empyemas treated with intrapleural tissue plasminogen activator (tPA) and deoxyribonuclease (DNase) compared with those treated with tPA alone or no intrapleural fibrinolytic therapy. The secondary outcome evaluated was the incidence of bleeding complications.

RESULTS

We identified 69 patients with a malignant pleural effusion and an IPC-related empyema. Twenty patients received tPA/DNase, 9 received tPA alone, and 40 were managed without fibrinolytics. Those treated with fibrinolytics were more likely to have their IPCs removed as part of the initial management strategy ( P =0.004). The rate of surgical intervention and mortality attributable to the empyema were not significantly different between treatment groups. There were no bleeding events in any group.

CONCLUSION

In patients with IPC-related empyemas, we did not find significant differences in the rates of surgical intervention, empyema-related mortality, or bleeding complications in those treated with intrapleural tPA/DNase, tPA alone, or no fibrinolytics. More patients who received intrapleural fibrinolytics had their IPCs removed, which may have been due to selection bias.

Indwelling pleural catheter infection and colonisation: a clinical practice review

Indwelling pleural catheters (IPCs) are used in the management of malignant pleural effusions, but they can become infected in 5.7% of cases. This review aims to provide a summary of the development of IPC infections and their microbiology, diagnosis and management. IPC infections can be deep, involving the pleural space, or superficial. The former are of greater clinical concern. Deep infection is associated with biofilm formation on the IPC surface and require longer courses of antibiotic treatment. Mortality from infections is low and it is common for patients to undergo pleurodesis following a deep infection. The diagnosis of pleural infections is based upon positive IPC pleural fluid cultures, changes in pleural fluid appearance and biochemistry, and signs or symptoms suggestive of infection. IPCs can also become colonised, where bacteria are grown from pleural fluid drained via an IPC but without evidence of infection. It is important to distinguish between infection and colonisation clinically, and though infections require antibiotic treatment, colonisation does not. It is unclear what proportion of IPCs become colonised. The most common causes of IPC infection and colonisation are Staphylococcus aureus and Coagulase-negative Staphylococci respectively. The management of deep IPC infections requires prolonged antibiotic therapy and the drainage of infected fluid, usually via the IPC. Intrapleural enzyme therapy (DNase and fibrinolytics) can be used to aid drainage. IPCs rarely need to be removed and patients can generally be managed as outpatients. Work is ongoing to study the incidence and significance of IPC colonisation. Other topics of interest include topical mupirocin to prevent IPC infections, and whether IPCs can be designed to limit infection risk.

Topical antibiotics prophylaxis for infections of indwelling pleural/peritoneal catheters (TAP-IPC): A pilot study

BACKGROUND AND OBJECTIVE

Indwelling pleural catheter (IPC) and indwelling peritoneal catheter (IPeC) have established roles in the management of malignant pleural and peritoneal effusions but catheter-related infections remain a major concern. Topical mupirocin prophylaxis has been shown to reduce peritoneal dialysis catheter infections. This study aimed to assess the (i) compatibility of IPC with mupirocin and (ii) feasibility, tolerability and compliance of topical mupirocin prophylaxis in patients with an IPC or IPeC.

METHODS

(i) Three preparations of mupirocin were applied onto segments of IPC thrice weekly and examined with scanning electron microscope (SEM) at different time intervals. (ii) Consecutive patients fitted with IPC or IPeC were given topical mupirocin prophylaxis to apply to the catheter exit-site following every drainage/dressing change (at least twice weekly) and followed up for 6 months.

RESULTS

(i) No detectable structural catheter damage was found with mupirocin applied for up to 6 months. (ii) Fifty indwelling catheters were inserted in 48 patients for malignant pleural (n = 41) and peritoneal (n = 9) effusions. Median follow-up was 121 [median, IQR 19-181] days. All patients tolerated mupirocin well; one patient reported short-term local tenderness. Compliance was excellent with 95.8% of the 989 scheduled doses delivered. Six patients developed catheter-related pleural (n = 3), concurrent peritoneal/local (n = 1) and skin/tract (n = 2) infections from Streptococcus mitis (with Bacillus species or anaerobes), Staphylococcus aureus, Klebsiella pneumoniae and Pseudomonas aeruginosa.

CONCLUSION

This first study of long-term prevention of IPC- or IPeC-related infections found topical mupirocin prophylaxis feasible and well tolerated. Its efficacy warrants future randomized studies.

Malignant pleural disease

Malignant pleural disease represents a growing healthcare burden. Malignant pleural effusion affects approximately 1 million people globally per year, causes disabling breathlessness and indicates a shortened life expectancy. Timely diagnosis is imperative to relieve symptoms and optimise quality of life, and should give consideration to individual patient factors. This review aims to provide an overview of epidemiology, pathogenesis and suggested diagnostic pathways in malignant pleural disease, to outline management options for malignant pleural effusion and malignant pleural mesothelioma, highlighting the need for a holistic approach, and to discuss potential challenges including non-expandable lung and septated effusions.

Indwelling Pleural Catheter: Management of Complications

Multiple randomized clinical trials have established the advantages of indwelling pleural catheter (IPC) in the management of malignant pleural effusions, resulting in its widespread adoption in clinical practice. Complications can occur with IPC use and must be recognized and managed effectively. This review provides a comprehensive overview of IPC complications and their best care. Pain postinsertion or during drainage of IPC is easily manageable and must be distinguished from tumor-related chest wall pain. IPC-related infections require systemic antibiotics and often intrapleural fibrinolytic/deoxyribonuclease therapy. The removal of IPC for infection is usually unnecessary. Symptomatic loculation usually responds to fibrinolytics but may recur. Catheter tract metastases are common in mesothelioma patients and usually respond to radiotherapy without inducing damages to the IPC. Less common complications include dislodgement, irreversible blockage, and fractures (upon removal) of the catheter. Recommendations on the management of IPC complications by recent consensus statement/guideline are discussed. Expert opinions on management approaches are included in areas where evidence is lacking to guide care.

A Narrative Review-Management of Malignant Pleural Effusion Related to Malignant Pleural Mesothelioma

Malignant pleural mesothelioma (MPM) is an aggressive, almost universally fatal cancer with limited therapeutic options. Despite efforts, a real breakthrough in treatment and outcomes has been elusive. Pleural effusion with significant breathlessness and pain is the most typical presentation of individuals with MPM. Although thoracentesis provides relief of breathlessness, most such pleural effusions recur rapidly, and a definitive procedure is often required to prevent a recurrence. Unfortunately, the optimal treatment modality for individuals with recurrent MPM-related effusion is unclear, and considerable variation exists in practice. In addition, non-expandable lung is common in pleural effusions due to MPM and makes effective palliation of symptoms more difficult. This review delves into the latest advances in the available management options (both surgical and non-surgical) for dealing with pleural effusion and non-expandable lung related to MPM. We discuss factors that determine the choice of definitive procedures that need to be tailored to the individual patient.

ERS/ESTS statement on the management of pleural infection in adults

Pleural infection is a common condition encountered by respiratory physicians and thoracic surgeons alike. The European Respiratory Society (ERS) and European Society of Thoracic Surgeons (ESTS) established a multidisciplinary collaboration of clinicians with expertise in managing pleural infection with the aim of producing a comprehensive review of the scientific literature. Six areas of interest were identified: 1) epidemiology of pleural infection, 2) optimal antibiotic strategy, 3) diagnostic parameters for chest tube drainage, 4) status of intrapleural therapies, 5) role of surgery and 6) current place of outcome prediction in management. The literature revealed that recently updated epidemiological data continue to show an overall upwards trend in incidence, but there is an urgent need for a more comprehensive characterisation of the burden of pleural infection in specific populations such as immunocompromised hosts. There is a sparsity of regular analyses and documentation of microbiological patterns at a local level to inform geographical variation, and ongoing research efforts are needed to improve antibiotic stewardship. The evidence remains in favour of a small-bore chest tube optimally placed under image guidance as an appropriate initial intervention for most cases of pleural infection. With a growing body of data suggesting delays to treatment are key contributors to poor outcomes, this suggests that earlier consideration of combination intrapleural enzyme therapy (IET) with concurrent surgical consultation should remain a priority. Since publication of the MIST-2 study, there has been considerable data supporting safety and efficacy of IET, but further studies are needed to optimise dosing using individualised biomarkers of treatment failure. Pending further prospective evaluation, the MIST-2 regimen remains the most evidence based. Several studies have externally validated the RAPID score, but it requires incorporating into prospective intervention studies prior to adopting into clinical practice.

Current status of and progress in the treatment of malignant pleural effusion of lung cancer

Malignant pleural effusion (MPE) is a common complication in the late stage of malignant tumors. The appearance of MPE indicates that the primary tumor has spread to the pleura or progressed to an advanced stage. The survival time of the patients will be significantly shortened, with a median survival of only a few months. There are a variety of traditional treatments, and their advantages and disadvantages are relatively clear. There are still many problems that cannot be solved by traditional methods in clinical work. The most common one is intrapleural perfusion therapy with chemotherapy drugs, but it has a large side effect of chemotherapy. At present, with the development of medical technology, there are a variety of treatment methods, and many innovative, significant and valuable treatment methods have emerged, which also bring hope for the treatment of refractory and recurrent MPE patients. Several clinical trials had confirmed that drug-carrying microparticles has less adverse reactions and obvious curative effect. However, there is still a long way to go to completely control and cure MPE, and the organic combination of clinical work and scientific research results is needed to bring dawn to refractory MPE patients.

Malignant pleural effusion diagnosis and therapy

Malignant pleural effusion (MPE) is a serious complication of advanced tumor, with relatively high morbidity and mortality rates, and can severely affect the quality of life and survival of patients. The mechanisms of MPE development are not well defined, but much research has been conducted to gain a deeper understanding of this process. In recent decades, although great progress has been made in the management of MPE, the diagnosis and treatment of MPE are still major challenges for clinicians. In this article, we provide a review of the research advances in the mechanisms of MPE development, diagnosis and treatment approaches. We aim to offer clinicians an overview of the latest evidence on the management of MPE, which should be individualized to provide comprehensive interventions for patients in accordance with their wishes, health status, prognosis and other factors.

Permanent indwelling catheter for the management of refractory malignant pericardial effusion

In this case report, we describe the novel use of a permanent indwelling catheter (PiC) in the management of refractory malignant pericardial effusion (PE). The patient had disseminated lung cancer and was hospitalised repeatedly with circulatory collapse due to malignant PE despite treatments with pericardiocentesis (PCC) and a pericardial window (PW). The PiC was inserted as a last resort with no complications and was a mediator of pericardiodesis (PCD), resulting in the cease of PE. The PiC could subsequently be removed, and there was no relapse of PE.

Indwelling pleural catheter for malignant pleural effusion with persistent air leak

Malignant pleural effusion with persistent air leak (PAL) is a rare manifestation of lung malignancy. We present a woman in her 50s with postpleuroscopy PAL. Pleural biopsy confirmed adenocarcinoma with detection of epidermal growth factor receptor mutation in exon 19. An indwelling pleural catheter (IPC) was inserted and connected to an Atrium Express Mini ambulatory drain. This procedure reduced the length of hospital stay. Autopleurodesis with resolution of PAL occurred at week 3 of IPC insertion.

Noninvasive Management of Fractured Indwelling Tunneled Pleural Catheter Valve

Tunneled indwelling pleural catheters (IPCs) are frequently used to palliate symptomatic dyspnea due to recurrent pleural effusions. The drainage valve of IPCs is an important component of the catheter as fracture of the valve leads to malfunctioning of the IPCs. Replacement of the catheter includes risks such as pain, infection, pneumothorax, and procedure cost. We report two cases of malfunctioning tunneled IPC drainage valves repaired by our noninvasive method and discuss the need for a repair kit and a standardized approach to this repair in case of nonavailability of repair kits.

Postoperative outcome after palliative treatment of malignant pleural effusion

BACKGROUND

The objective of this nationwide, registry-based study was to compare the two most frequently used procedures for the palliative treatment of a malignant pleural effusion (MPE) and to evaluate differentiated indications for these two procedures.

METHODS

This was a retrospective observational study based on data of the "PLEURATUMOR" registry of the German Society for Thoracic Surgery. Patients who were documented in the period from January 2015 to November 2021 and had video-assisted thoracic surgery (VATS) talc pleurodesis or implantation of an indwelling pleural catheter (IPC) were included.

RESULTS

A total of 543 patients were evaluated. The majority suffered from secondary pleural carcinomatosis (n = 402; 74%). VATS talc pleurodesis (n = 361; 66.5%) was performed about twice as often as IPC implantation (n = 182; 33.5%). The duration of surgery was significantly shorter in IPC-patients with 30 min compared to VATS talc pleurodesis (38 min; p = 0.000). Postoperative complication rate was 11.8% overall and slightly higher after VATS talc pleurodesis (n = 49; 13.6%) than after IPC implantation (n = 15; 8.2%). After VATS talc pleurodesis patients were hospitalized significantly longer compared to the IPC group (6 vs. 3.5 days; p = 0.000). There was no significant difference in postoperative wound infections between the groups (p = 0.10). The 30-day mortality was 7.9% (n = 41).

CONCLUSION

The implantation of an IPC can significantly shorten the duration of surgery and the hospital stay. For this reason, the procedure should be matched with the patient's expectations preoperatively and the use of an IPC should be considered not only in the case of a trapped lung.

Diagnosis and Management of Malignant Pleural Effusion: A Decade in Review

Malignant pleural effusion (MPE) is a common complication of thoracic and extrathoracic malignancies and is associated with high mortality. Treatment is mainly palliative, with symptomatic management achieved via effusion drainage and pleurodesis. Pleurodesis may be hastened by administering a sclerosing agent through a thoracostomy tube, thoracoscopy, or an indwelling pleural catheter (IPC). Over the last decade, several randomized controlled studies shaped the current management of MPE in favor of an outpatient-based approach with a notable increase in IPC usage. Patient preferences remain essential in choosing optimal therapy, especially when the lung is expandable. In this article, we reviewed the last 10 to 15 years of MPE literature with a particular focus on the diagnosis and evolving management.

Optimizing the management of complicated pleural effusion: From intrapleural agents to surgery

Pleural effusion is a frequent complication of acute pulmonary infection and can affect its morbidity and mortality. The possible evolution of a parapneumonic pleural effusion includes 3 stages: exudative (simple accumulation of pleural fluid), fibropurulent (bacterial invasion of the pleural cavity), and organized stage (scar tissue formation). Such a progression is favored by inadequate treatment or imbalance between microbial virulence and immune defenses. Biochemical features of a fibrinopurulent collection include a low pH (<7.20), low glucose level (<60 mg/dl), and high lactate dehydrogenase (LDH). A parapneumonic effusion in the fibropurulent stage is usually defined "complicated" since antibiotic therapy alone is not enough for its resolution and an invasive procedure (pleural drainage or surgery) is required. Chest ultrasound is one of the most useful imaging tests to assess the presence of a complicated pleural effusion. Simple parapneumonic effusions are usually anechoic, whereas complicated effusions often have a complex appearance (non-anechoic, loculated, or septated). When simple chest tube placement fails and/or patients are not suitable for more invasive techniques (i.e. surgery), intra-pleural instillation of fibrinolytic/enzymatic therapy (IPET) might represent a valuable treatment option to obtain the lysis of fibrin septa. IPET can be used as either initial or subsequent therapy. Further studies are ongoing or are required to help fill some gaps on the optimal management of parapneumonic pleural effusion. These include the duration of antibiotic therapy, the risk/benefit ratio of medical thoracoscopy and surgery, and new intrapleural treatments such as antibiotic-eluting chest tubes and pleural irrigation with antiseptic agents.

Malignant Pleural Effusions

Malignant pleural effusions have a significant burden on patients and the health care system. Diagnosis is typically via thoracentesis, although other times more invasive procedures are required. Management centers around relief of dyspnea and patient quality of life and can be done via serial thoracentesis, indwelling pleural catheter, or pleurodesis. This article focuses on the diagnosis and management of malignant pleural effusion.

Modern day management of a unilateral pleural effusion

Over 50 systemic conditions may affect the pleura and, thus, unilateral pleural effusions may present for a variety of reasons. Investigating the cause is essential to providing appropriate management. Various pleural interventions are available in current practice, but have varying diagnostic sensitivity. It is, therefore, vital to consider the intervention with the highest diagnostic yield appropriate to the particular clinical situation. The diagnostic pathway in unilateral pleural effusion is increasingly outpatient based, avoiding hospitalisation, which is particularly relevant with the recent COVID-19 pandemic.

Managing complications of pleural procedures

Pleural disease is common and often requires procedural intervention. Given this prevalence, pleural procedures are performed by a wide range of providers with varying skill level in both medical and surgical specialties. Even though the overall complication rate of pleural procedures is low, the proximity to vital organs and blood vessels can lead to serious complications which if left unrecognized can be life threatening. As a result, it is of the utmost importance for the provider to have a firm grasp of the local anatomy both conceptually when preparing for the procedure and physically, via physical exam and the use of a real time imaging modality such as ultrasound, when performing the procedure. With this in mind, anyone who wishes to safely perform pleural procedures should be able to appropriately anticipate, quickly identify, and efficiently manage any potential complication including not only those seen with many procedures such as pain, bleeding, and infection but also those specific to procedures performed in the thorax such as pneumothorax, re-expansional pulmonary edema, and regional organ injury. In this article, we will review the basic approach to most pleural procedures along with essential local anatomy most often encountered during these procedures. This will lay the foundation for the remainder of the article where we will discuss clinical manifestations and management of various pleural procedure complications.

Management of Advanced Pleural Mesothelioma-At the Crossroads

The management of pleural mesothelioma has changed with the demonstration that first-line checkpoint blockade therapy improves survival. This review covers issues of relevance to the practicing medical oncologist, with an emphasis on the palliative setting and on new information. Until recently, standard systemic therapy for mesothelioma was combination chemotherapy with platinum and pemetrexed. In 2020, combination immunotherapy with ipilimumab and nivolumab was approved as first-line systemic therapy for mesothelioma following release of the results from the CheckMate 743 trial. This trial showed improved overall survival for patients receiving ipilimumab and nivolumab over those treated with platinum and pemetrexed chemotherapy. When the survival results were examined by histologic subtype, the survival benefit was most significant in those with nonepithelioid mesothelioma, a group for which combination immunotherapy is now standard of care. The most important outstanding issue from CheckMate-743 is a better understanding, through translational studies, of which patients with epithelioid mesothelioma may benefit from combination immunotherapy. The next generation of first-line clinical trials in mesothelioma will report the results of first-line combination chemoimmunotherapy. For those patients who receive first-line dual checkpoint blockade, there is no evidence as to the efficacy of subsequent chemotherapy. However, given the known first-line efficacy of cisplatin or carboplatin and pemetrexed, combination chemotherapy is an appropriate subsequent choice for those who progress on or after dual immunotherapy. For those who previously received chemotherapy without immunotherapy, single-agent nivolumab provides benefit over best supportive care. In summary, both chemotherapy and immunotherapy should be considered for all patients during their disease course. Another topical issue is the growing appreciation that some individuals have an inherited predisposition to mesothelioma; referral to a clinical geneticist should be considered under some circumstances. The role of surgery and multimodality therapy is controversial, with results awaited from the fully recruited MARS-2 clinical trial. Patient selection, staging, and multidisciplinary review are critical to identify those who might benefit from a multimodality approach. Finally, a proactive, multidisciplinary approach to symptom management and the principles of management of pleural effusions are critical to manage the symptom burden of mesothelioma and optimize patient well-being.

Association between Tunneled Pleural Catheter Use and Infection in Patients Immunosuppressed from Antineoplastic Therapy. A Multicenter Study

Rationale: Patients with malignant or paramalignant pleural effusions (MPEs or PMPEs) may have tunneled pleural catheter (TPC) management withheld because of infection concerns from immunosuppression associated with antineoplastic therapy.Objectives: To determine the rate of infections related to TPC use and to determine the relationship to antineoplastic therapy, immune system competency, and overall survival (OS).Methods: We performed an international, multiinstitutional study of patients with MPEs or PMPEs undergoing TPC management from 2008 to 2016. Patients were stratified by whether or not they underwent antineoplastic therapy and/or whether or not they were immunocompromised. Cumulative incidence functions and multivariable competing risk regression analyses were performed to identify independent predictors of TPC-related infection. Kaplan-Meier method and multivariable Cox proportional hazards modeling were performed to examine for independent effects on OS.Results: A total of 1,408 TPCs were placed in 1,318 patients. Patients had a high frequency of overlap between antineoplastic therapy and an immunocompromised state (75-83%). No difference in the overall (6-7%), deep pleural (3-5%), or superficial (3-4%) TPC-related infection rates between subsets of patients stratified by antineoplastic therapy or immune status was observed. The median time to infection was 41 (interquartile range, 19-87) days after TPC insertion. Multivariable competing risk analyses demonstrated that longer TPC duration was associated with a higher risk of TPC-related infection (subdistribution hazard ratio, 1.03; 95% confidence interval [CI], 1.00-1.06; P = 0.028). Cox proportional hazards analysis showed antineoplastic therapy was associated with better OS (hazard ratio, 0.84; 95% CI, 0.73-0.97; P = 0.015).Conclusions: The risk of TPC-related infection does not appear to be increased by antineoplastic therapy use or an immunocompromised state. The overall rates of infection are low and comparable with those of immunocompetent patients with no relevant antineoplastic therapy. These results support TPC palliation for MPE or PMPEs regardless of plans for antineoplastic therapy.

Malignant pleural mesothelioma: recent developments

PURPOSE OF REVIEW

Malignant pleural mesothelioma (MPM) is a rare, but aggressive tumor with still poor prognosis. In this article, we focus on recent developments in the management of MPM including diagnosis, staging, biomarkers, and treatment strategies.

RECENT FINDINGS

Molecular markers such as programmed death-ligand 1 (PDL-1), Breast Cancer gene 1-associated protein gene, and cyclin-dependent kinase inhibitor 2A (CDKN2A) have prognostic impact and should be considered for assessment in patient samples. In addition to histological subtype and tumor pattern, tumor volumetry plays an increasing important role in staging, assessment of treatment response, and prediction of survival. Several new blood-based biomarkers have been recently reported including peripheral blood DNA methylation, microRNAs, fibulin, and high-mobility group box 1, but have not been established in clinical routine use yet. Regarding treatment, targeted therapies, immunotherapy, and vaccination are considered as new promising strategies. Moreover, extended pleurectomy/decortication is favored over extrapleural pneumonectomy (EPP) and intensity-modulated radiotherapy represents a possible approach in combination with EPP and pleurectomy/decortication. Intracavitary treatment options are promising and deserve further investigations.

SUMMARY

Overall, there has not been a real breakthrough in the treatment of MPM. Further research and clinical trials are needed to evaluate outcome and to identify new potential treatment candidates.

The minimum standard of care for managing malignant pleural mesothelioma in developing nations within the Asia-Pacific Region

Malignant pleural mesothelioma (MPM) is an incurable malignancy associated with high symptom burden and poor prognosis. The relationship between asbestos exposure and MPM incidence is well-established. The incidence rate of MPM in Australia and New Zealand is among the highest globally. Matching the experience of other nations with legal restrictions on asbestos, incidence is expected to fall. In contrast, the incidence of MPM is rising in the developing nations of the Asia-Pacific as consumption and mining (albeit to a lesser extent) of asbestos continues. The incidence of MPM in these nations is currently low or unknown, reflecting insufficient latency periods since industrial use of asbestos, deficient resources for accurate diagnosis, and lack of occupational disease or cancer registries. The landscape of treatment for MPM is rapidly changing with combination immunotherapy now demonstrating improved survival in the first-line setting. Considering vast global inequity in access to anticancer treatments, establishing minimum standard of care for MPM in developing nations is of greater significance. Here, we review the evidence that form the basis of our minimum-standard recommendations for diagnosis, systemic treatment, management of recurrent pleural effusions, and symptom management. We also briefly review evidence-based treatment that may be considered for those with access.

Yellow nail syndrome with massive chylothorax after esophagectomy: A case report

Yellow nail syndrome (YNS) is a rare condition characterized by the triad of yellow nails, lymphedema, and respiratory manifestations. Diuretics and thoracic drainage are often not effective in YNS, and the most effective treatments are pleurodesis and decortication/pleurectomy. A 66-year-old man was admitted to our hospital for YNS after esophagectomy with gastric tube reconstruction for esophageal cancer. The patient presented with yellow nails and lymphedema. Chest X-rays and computed tomography showed massive pleural effusions and ascites that were both chylous. The patient was considered to have YNS that became apparent after surgery. He recovered with diuretics and a low-fat diet without pleurodesis and decortication/pleurectomy. Thoracic surgery can exacerbate the functional impairment of lymphatic drainage in patients with asymptomatic and undiagnosed YNS, and can lead to further development of YNS-related clinical symptoms. Despite relatively massive chylothorax following thoracic surgery, chylothorax related to YNS could be successfully controlled with conservative treatment without pleurodesis and decortication/pleurectomy.

Complications and management of a long-term pleural access port in a dog with chronic chylothorax associated with lung lobe torsion

A 2-year-old neutered male 35-kg golden retriever mixed breed dog was presented because of a 3-day history of increased respiratory effort. The patient was subsequently diagnosed with a lung lobe torsion and underwent lung lobectomy. Chylothorax developed after surgery and persisted for 3.5 y. Pleural access port (PAP) placement was used for long-term medical management. Several complications were encountered, including 2 episodes of PAP occlusion that were successfully treated with unfractionated heparin. The dog had a surgical site seroma and 2 episodes of pleuritis; euthanasia was elected after the second episode. Key clinical message: This case demonstrates successful long-term management of chylothorax with a pleural access port and management of 3 complications. Instead of the less accessible and more expensive tissue plasminogen activator, unfractionated heparin was used as an effective treatment for PAP occlusions.

Use of indwelling pleural/peritoneal catheter in the management of malignant ascites: a retrospective study of 48 patients

BACKGROUND

Patients suffering from malignant ascites usually require repeated large volume paracentesis (LVP) for symptomatic relief. This often requires hospital admission and has inherent risks.

AIMS

To report the first Australian experience of placing tunnelled indwelling peritoneal catheters (IPeC) for management of recurrent malignant ascites.

METHODS

A retrospective study was conducted of tunnelled IPeC use in patients with symptomatic malignant ascites in four hospitals in Western Australia (from 2010 to 2018). Procedure data, success rate and safety profile were collected from a database.

RESULTS

Forty-eight patients (median age 65 years; female 56%) underwent 51 peritoneal catheter insertion procedures that were performed mostly by pleural specialists. The majority of patients (96%) had prior LVP (median two drainages, interquartile range (IQR) 1-4) before IPeC insertion. The IPeC was inserted successfully under ultrasound guidance in all patients. The median length of hospital stay for IPeC insertion and initial ascites drainage was 2 days (IQR 2-3 days) and most patients (96%) did not require further paracentesis after IPeC placement. The majority (96%) of patients experienced relief from ascites symptoms after catheter insertion. Most IPeC-related adverse events were self-limiting, including pain (in 25% cases), transient hypotension after initial fluid drainage (10%), peritoneal fluid leakage (10%), bacterial peritonitis (8%), fluid loculation (2%) and catheter dislodgement (2%). Six (12%) patients had IPeC removed. All patients with bacterial peritonitis responded to antibiotics and one required catheter removal.

CONCLUSIONS

Use of tunnelled IPeC improves symptoms and can minimise further invasive drainage procedures in patients with symptomatic malignant ascites. Placement of IPeC was associated with a low rate of adverse events, most of which could be managed conservatively.

Successful treatment of a complex malignant pleural effusion with 1 mg alteplase instilled through a non-draining indwelling pleural catheter

Indwelling pleural catheter (IPC) is the treatment of choice in managing symptomatic recurrent malignant pleural effusion (MPE). Loculated effusions following insertion may occur due to infection, catheter malfunction or the inflammatory nature of MPE. Loculations may lead to ineffective drainage and make the IPC non-functional. We report a 56-year-old man with symptomatic loculated malignant pleural effusion with an IPC, successfully drained with a single dose of 1 mg recombinant tissue plasminogen activator alteplase. This is the lowest dose currently applied in our centre for efficient drainage and improvement of dyspnoea.

Re-establishing indwelling pleural catheter patency with alteplase after failure of streptokinase

Indwelling pleural catheter (IPC) has revolutionized the management of malignant pleural effusion (MPE). IPC is relatively safe, although complications can occur. We report a 53-year-old woman with stage IVA lung adenocarcinoma and recurrent MPE. Two months post insertion, the IPC was blocked with residual effusion and presence of new loculations. Attempts to restore patency with six doses of intrapleural (IP) streptokinase failed. She was referred to our centre for further management. We used a single dose of 2.5 mg IP alteplase which was successful in establishing patency of the IPC and draining the effusion. This case highlights the safety and efficacy of IP alteplase via IPC following a failed instillation of streptokinase.

Predicting the survival in patients with malignant pleural effusion undergoing indwelling pleural catheter insertion

CONTEXT

Malignant pleural effusion (MPE) is a common comorbid condition in advanced malignancies with variable survival.

AIMS

The aim of this study was to predict the survival in patients with MPE undergoing indwelling pleural catheter (IPC) insertion.

SETTINGS AND DESIGN

This was a cross-sectional study conducted at Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan.

METHODS

One hundred and ten patients with MPE who underwent IPC insertion from January 2011 to December 2019 were reviewed. Kaplan-Meier method was used to determine the overall survival (OS) of the patient's cohort with respect to LENT score.

STATISTICAL ANALYSIS USED

The IBM SPSS version 20 was used for statistical analysis.

RESULTS

We retrospectively reviewed 110 patients who underwent IPC insertion for MPE, with a mean age of 49 ± 15 years. 76 (69.1%) patients were females, of which majority 59 (53.6%) had a primary diagnosis of breast cancer. The LENT score was used for risk stratification, and Kaplan-Meier survival curves were used to predict the OS. The proportion of patients with low-risk LENT score had 91%, 58%, and 29% survival, the moderate-risk group had 76%, 52%, and 14% survival, and in the high-risk group, 61%, 15%, and 0% patients survived at 1, 3, and 6 months, respectively. In addition, there was a statistically significant survival difference (P = 0.05) in patients who received chemotherapy pre- and post-IPC insertion.

CONCLUSIONS

LENT score seems to be an easy and attainable tool, capable of predicting the survival of the patients with MPE quite accurately. It can be helpful in palliating the symptoms of patients with advanced malignancies by modifying the treatment strategies.

AABIP Evidence-informed Guidelines and Expert Panel Report for the Management of Indwelling Pleural Catheters

BACKGROUND

While the efficacy of Indwelling pleural catheters for palliation of malignant pleural effusions is supported by relatively robust evidence, there is less clarity surrounding the postinsertion management.

METHODS

The Trustworthy Consensus-Based Statement approach was utilized to develop unbiased, scientifically valid guidance for the management of patients with malignant effusions treated with indwelling pleural catheters. A comprehensive electronic database search of PubMed was performed based on a priori crafted PICO questions (Population/Intervention/Comparator/Outcomes paradigm). Manual searches of the literature were performed to identify additional relevant literature. Dual screenings at the title, abstract, and full-text levels were performed. Identified studies were then assessed for quality based on a combination of validated tools. Appropriateness for data pooling and formation of evidence-based recommendations was assessed using predetermined criteria. All panel members participated in development of the final recommendations utilizing the modified Delphi technique.

RESULTS

A total of 7 studies were identified for formal quality assessment, all of which were deemed to have a high risk of bias. There was insufficient evidence to allow for data pooling and formation of any evidence-based recommendations. Panel consensus resulted in 11 ungraded consensus-based recommendations.

CONCLUSION

This manuscript was developed to provide clinicians with guidance on the management of patients with indwelling pleural catheters placed for palliation of malignant pleural effusions. Through a systematic and rigorous process, management suggestions were developed based on the best available evidence with augmentation by expert opinion when necessary. In addition, these guidelines highlight important gaps in knowledge which require further study.

Malignant Pleural Effusion: Diagnosis and Management

Symptomatic malignant pleural effusion is a common clinical problem. This condition is associated with very high mortality, with life expectancy ranging from 3 to 12 months. Studies are contributing evidence on an increasing number of therapeutic options (therapeutic thoracentesis, thoracoscopic pleurodesis or thoracic drainage, indwelling pleural catheter, surgery, or a combination of these therapies). Despite the availability of therapies, the management of malignant pleural effusion is challenging and is mainly focused on the relief of symptoms. The therapy to be administered needs to be designed on a case-by-case basis considering patient's preferences, life expectancy, tumour type, presence of a trapped lung, resources available, and experience of the treating team. At present, the management of malignant pleural effusion has evolved towards less invasive approaches based on ambulatory care. This approach spares the patient the discomfort caused by more invasive interventions and reduces the economic burden of the disease. A review was performed of the diagnosis and the different approaches to the management of malignant pleural effusion, with special emphasis on their indications, usefulness, cost-effectiveness, and complications. Further research is needed to shed light on the current matters of controversy and help establish a standardized, more effective management of this clinical problem.

Thoracic ultrasound as a predictor of pleurodesis success at the time of indwelling pleural catheter removal

BACKGROUND AND OBJECTIVE

IPC in patients with MPE are removed within 3 months in 30-58% of cases, usually due to decreased pleural fluid output as a result of pleurodesis. Disease control can also account for the lack of fluid output, potentially explaining why 4-14% of patients undergo repeat pleural intervention for fluid re-accumulation (at the time of disease recurrence or progression). The aim of our pilot study is to determine the accuracy of thoracic ultrasound (TUS) in predicting pleurodesis success in patients with MPE at the time of IPC removal.

METHODS

This is a single-centre, prospective observational cohort study that enrolled consecutive patients with confirmed MPE treated with IPC at the time of IPC removal. TUS was performed to calculate a PAS. Patients were followed up for a minimum of 3 months. Failure was defined as pleural fluid recurrence within 3 months.

RESULTS

Twenty-seven patients were screened and 25 were included in the final analysis. Pleurodesis success was observed in 88% (n = 22) and failure in 12% (n = 3) of patients. The mean PAS was higher in patients with pleurodesis success (22.0 vs 9.3, P = 0.01). A PAS greater than 10 predicted pleurodesis success with a sensitivity of 100% and specificity of 86%.

CONCLUSION

This pilot study suggests that TUS at the time of IPC removal accurately identifies patients who have achieved pleurodesis and therefore will not have re-accumulation of pleural effusion or require an ipsilateral pleural intervention for at least 3 months post-IPC removal.

Pleural effusions and pneumothorax: Beyond simple plumbing: Expert opinions on knowledge gaps and essential next steps

Pleural diseases affect millions of people worldwide. Pleural infection, malignant pleural diseases and pneumothorax are common clinical challenges. A large number of recent clinical trials have provided an evidence-based platform to evaluate conventional and novel methods to drain pleural effusions/air which reduce morbidity and unnecessary interventions. These successes have generated significant enthusiasm and raised the profile of pleural medicine as a new subspecialty. The ultimate goal of pleural research is to prevent/stop development of pleural effusions/pneumothorax. Current research studies mainly focus on the technical aspects of pleural drainage. Significant knowledge gaps exist in many aspects such as understanding of the pathobiology of the underlying pleural diseases, pharmacokinetics of pleural drug delivery, etc. Answers to these important questions are needed to move the field forward. This article collates opinions of leading experts in the field in highlighting major knowledge gaps in common pleural diseases to provoke thinking beyond pleural drainage. Recognizing the key barriers will help prioritize future research in the quest to ultimately cure (rather than just drain) these pleural conditions.

Indications and clinical outcomes of indwelling pleural catheter placement in patients with malignant pleural effusion in a cancer setting hospital

BACKGROUND

The placement of indwelling pleural catheters (IPC) is an effective outpatient approach for the management of malignant pleural effusions (MPE).

AIMS

The indications and outcome of IPC in patients with MPE. Risk stratifications, prevention and management of IPC-related complications.

METHODS

We retrospectively reviewed the clinical data of patients with MPE who underwent IPC insertion from July 2011 to July 2019. The multivariable logistic regression model was used to identify the independent risk factors associated with IPC infection and the Kaplan-Meier method to determine the overall survival.

RESULTS

A total of 102 patients underwent IPC insertion during the stipulated period and the mean age was 50.49 ± 14.36 years. Seventy-one (69.6%) were females. The indications were Trap Lung in 38 (37.3%), failed talc pleurodesis in 28 (27.5%) and as a primary intervention in 36 (35.3%). The infection rate was 25.5%, of which 65.4% patients had nosocomial infections. Post-IPC overall median survival time was 9.0 ± 2.50 weeks with highest in patients with trap lung (18 ± 1.50 weeks). In multivariable analysis, following variables were identified as a significant independent risk factor for IPC infection: Multiloculated MPE (AOR 2.80; 95%CI (1.00-9.93), 0.04), trap lung (AOR 7.57; 95%CI (1.39-41.25), 0.01), febrile neutropenia (FN) (AOR 28.55; 95%CI (4.23-19.74), 0.001), IPC domiciliary education (AOR 0.18; 95%CI (0.05-0.66), 0.001) and length of hospital stay (AOR 1.16; 95%CI (1.01-1.33), 0.03).

CONCLUSION

IPC insertion is an effective management for MPE with reasonable survival benefits. Infection is the most common complication, of which mostly are nosocomial infections with higher incidence in multiloculated effusions, trap lung, FN and with lack of domiciliary IPC care education.

Effective drain care and management in community settings

The literature indicates that drain monitoring is a frequently undervalued aspect of patient care, and that the drain care provided is often inconsistent and inadequate. There are numerous potential implications of suboptimal drain care for patients, nurses, teams and healthcare organisations. Since acute care is increasingly being delivered in the community, there is a greater need for nurses to have an understanding of effective drain care. This article describes the rationale for drain insertion and its associated complications. It uses a case study to illustrate how suboptimal drain monitoring and documentation can negatively affect patient care and safety. This article also discusses several important issues raised in the case study, such as suboptimal documentation, and how these may have consequences for nurses, teams and healthcare organisations. Recognition of these elements supports initiatives that nurses could apply to practice to reduce the occurrence of similar incidents.

Multidisciplinary approaches to the management of malignant pleural effusions: a guide for the clinician

INTRODUCTION

Malignant pleural effusion (MPE) is a complication of advanced cancer, associated with significant mortality and morbidity. This entity is commonly treated by respiratory physicians, oncologists, and thoracic surgeons. There have been various randomized clinical trials assessing the relative merits of chest drain pleurodesis, indwelling pleural catheters, treatment of septated MPEs, the use of thoracoscopy and pleurodesis and pleurodesis through IPCs in the past decade which have addressed some key areas in the management of MPEs, with an increasing focus on patient related outcome.

AREAS COVERED

In this review, we examine and review the literature for management strategies for MPEs and discuss future directions. A detailed search of scientific literature and clinical trial registries published in the past two decades was undertaken.

EXPERT OPINION

Tremendous progress has been made in management of MPE in the past decade and current strategy involves patient preference along with local expertise that is available.

High-pressure leakage of pleural fluid through the healed entry site of the indwelling pleural catheter from undrained locules

The indwelling pleural catheter (IPC) is an established treatment for recurrent pleural effusion. Fluid leakage through the IPC insertion tract has been reported, but its occurrence is only limited to a short period after the procedure. Besides, the drainage efficacy of IPC may be limited by the presence of loculation in the pleural space, especially when intrapleural fibrinolytic is contraindicated. We report a case of fluid leakage through the healed entry site of IPC due to high pressure built from undrained pleural fluid locules, which was successfully treated with an additional drain targeting the largest undrained locule.

Management of Malignant Pleural Effusions

Malignant pleural effusion frequently complicates both solid and hematologic malignancies and is associated with high morbidity, mortality, and health care costs. Although no pleura-specific therapy is known to impact survival, both pleurodesis and indwelling pleural catheter (IPC) placement can significantly alleviate symptoms and improve quality of life. The optimal choice of therapy in terms of efficacy and particularly cost-effectiveness depends on patient preferences and individual characteristics, including lung expansion and life expectancy. Attempting chemical pleurodesis through an IPC in the outpatient setting appears to be a particularly promising approach in the absence of a nonexpandable lung.

Indwelling pleural catheters for malignancy-associated pleural effusion: report on a single centre's ten years of experience

Introduction

Recurrent pleural effusion is a common cause of dyspnoea, cough and chest pain during the course of malignant diseases. Chemical pleurodesis had been the only definitive treatment option until two decades ago. Indwelling pleural catheters (IPC) emerged as an alternative, not only assuring immediate symptom relief but also potentially leading to pleurodesis in the absence of sclerosing agents.

Methods

In this single-centre retrospective observational study patient characteristics, procedural variables and outcome in a large population of patients with IPC in malignancy were evaluated and prognostic factors for pleurodesis were identified.

Results

From 2006 to 2016, 395 patients received 448 IPC, of whom 121 (30.6%) had ovarian, 91 (23.0%) lung and 45 (11.4%) breast cancer. The median length of IPC remaining in place was 1.2 months (IQR, 0.5–2.6), the median survival time after insertion 2.0 months (IQR, 0.6–6.4). An adequate symptom relief was achieved in 94.9% of all patients, with no need for subsequent interventions until last visit or death. In patients surviving ≥30 days after IPC insertion, pleurodesis was observed in 44.5% and was more common in patients < 60 years (HR, 1.72; 95% CI, 1.05–2.78; p = 0.03). The use of an additional talc slurry via the IPC was highly predictive for pleurodesis (HR 6.68; 95% CI, 1.44–31.08; p = 0.02). Complications occurred in 13.4% of all procedures (n = 60), 41.8% concerning infections (local infections at the tunnel/exit site (n = 14) and empyema (n = 11)), and 98.3% being low or mild grade (n = 59). Complication rates were higher in men than women (18.6 vs. 12.4%, p = 0.023).

Conclusion

High efficacy in symptom relief and a favourable safety profile confirm IPC as suitable first line option in most malignant pleural effusions. The study presents the largest dataset on IPC in gynaecologic cancer to date. Gender-specific differences in complication rates warrant further study.

Novel complications of the tunnelled indwelling pleural catheter

Tunnelled indwelling pleural catheters (TIPC) are a modality of treatment for malignant pleural effusions. Though relatively easy, safe and efficacious, they are associated with a small risk of complications. We describe newer complications of the TIPC including the retention of the polyester plug and the blockage of the catheter with thick organised material consisting of malignant cells taking the shape of the catheter.

Role of Interventional Radiology in the Management of Infection

Interventional radiology (IR) is plays a crucial role in the management of localized infections, utilizing percutaneous access to loculated fluid collections for drainage and source control. Interventions have been developed in multiple organs and systems and used over decades, allowing the IR physician to provide patient care in many cases where surgical options are not optimal. In this review, we will examine the emergent, urgent, and routine nature of various IR procedures in the infectious context and timelines for each in regards to the decision making process. An algorithmic approach should guide the clinician's decision making for IR procedures in both large academic centers and smaller community hospitals. This approach and the pertinent procedural technique are described for multiple systems and organs including the biliary tree, gallbladder, genitourinary tract, and thoracic, abdominal, and pelvic abscesses. Increased awareness of the abilities and limitations of IR physicians in clinical scenarios needs to be implemented, to allow multispecialty input in efforts to decrease morbidity and mortality.
