The effectiveness of small-bore intercostal catheters versus large-bore chest tubes in the management of pleural disease with the systematic review of literature

Chest tube size selection for pleural effusion: from the perspective of thoracic surgeons and pulmonologists

BACKGROUND

The current discourse within the thoracic surgical and pulmonological communities pertains to a contentious debate over the optimal selection criteria for thoracostomy tube diameters utilized in the management of pleural effusions. A comprehensive examination of the variables that inform the clinical decision-making paradigm for the determination of appropriate chest tube calibers is imperative to enhance patient management and elevate the prognostic results.

OBJECTIVES

The objective of this inquiry is to elucidate the determinants that influence thoracic surgeons and pulmonologists in their selection of chest tube size for the management of pleural effusions.

METHODS

This cross-sectional study was based on an electronic questionnaire that was sent to the targeted populations through e-mail or a professional WhatsApp. The survey assessed the considerations of chest tube size selection as well as the respective advantages, disadvantages, and potential complications related to each size.

RESULTS

The conducted study encompassed participants, with a nearly even distribution between thoracic surgeons (49.1%) and pulmonologists (50.9%). Most of these practitioners are within tertiary-level medical institutions (82.1%). A preference for small-bore chest tubes (SBCT), defined as < 14 French (Fr), was indicated by 54.8% of participants. The drawbacks associated with SBCT, such as kinking (60%) and blockage (70%), influenced the decision-making process negatively, while pain was a significant factor in the selection against LBCT (64%). Ultrasound guidance was a positive influence for the selection of SBCT (55%). Complications associated with LBCT included visceral and vascular injuries (55.7%), wound infection (45.3%), re-expansion pulmonary edema (43.3%), and subcutaneous emphysema (57.5%). In contrast, malposition was a complication more commonly associated with SBCT (49.1%).

CONCLUSION

The decision regarding chest tube size was influenced by several critical factors which included the nature of pleural effusion, the volume of pleural fluid, and potential complications specific to the size of the chest tube used.

Infective Pleural Effusions-A Comprehensive Narrative Review Article

Infective pleural effusions are mainly represented by parapneumonic effusions and empyema. These conditions are a spectrum of pleural diseases that are commonly encountered and carry significant mortality and morbidity rates reaching upwards of 50%. The causative etiology is usually an underlying bacterial pneumonia with the subsequent seeding of the infectious culprit and inflammatory agents to the pleural space leading to an inflammatory response and fibrin deposition. Radiographical evaluation through a CT scan or ultrasound yields high specificity and sensitivity, with features such as septations or pleural thickening indicating worse outcomes. Although microbiological yields from pleural studies are around 56% only, fluid analysis assists in both diagnosis and prognosis by evaluating pH, glucose, and other biomarkers such as lactate dehydrogenase. Management centers around antibiotic therapy for 2-6 weeks and the drainage of the infected pleural space when the effusion is complicated through tube thoracostomies or surgical intervention. Intrapleural enzymatic therapy, used to increase drainage, significantly decreases treatment failure rates, length of hospital stay, and surgical referrals but carries a risk of pleural hemorrhage. This comprehensive review article aims to define and delineate the progression of parapneumonic effusions and empyema as well as discuss pathophysiology, diagnostic, and treatment modalities with aims of broadening the generalist's understanding of such complex disease by reviewing the most recent and relevant high-quality evidence.

Reintervention Rate After Pigtail Catheter Insertion Compared to Surgical Chest Tubes

BACKGROUND

Prior studies suggest similar efficacy between large-bore chest tube (CT) placement and small-bore pigtail catheter (PC) placement for the treatment of pleural space processes. This study examined reintervention rates of CT and PC in patients with pneumothorax, hemothorax, and pleural effusion.

METHODS

This retrospective study examined patients from September 2015 through December 2020. Patients were identified using ICD codes for pneumothorax, hemothorax, or pleural effusion. Use of a pigtail catheter (≤14Fr) or surgical chest tube (≥20Fr) was noted. The primary outcome was overall reintervention rate within 30 days of tube insertion. Patients who died with a pleural drainage catheter in place, unrelated to complications from chest tube placement, were excluded.

RESULTS

There were 1032 total patients in the study: 706 CT patients and 326 PC patients. The PC group was older with more comorbidities and more likely to have effusion as the indication for pleural drainage. Patients with PC were 2.35 times more likely to have the tube replaced or repositioned (P < .0001), 1.77 times more likely to require any reintervention (P = .001) and 2.09 times more likely to remain in the hospital >14 days (P < .0001) compared to patients with CT.

CONCLUSION

PCs have a significantly higher reintervention rate compared to CT for the treatment of pneumothorax, hemothorax, and pleural effusion. Although PC are believed to cause less pain and tissue trauma, they do not necessarily drain the pleural space as well as CT. Decisions on which method of draining the chest should be made on a case-by-case basis.

Double-Pigtail Drainage Catheter: A New Design for Efficient Pleural Drainage

Background and Objectives: The novel double-pigtail catheter (DPC) has an additional pigtail coiling at the mid-shaft with multiple centripetal side holes. The present study aimed to investigate the advantages and efficacy of DPC in overcoming the complications of conventional single-pigtail catheters (SPC) used to drain pleural effusion. Materials and Methods: Between July 2018 and December 2019, 382 pleural effusion drainage procedures were reviewed retrospectively (DPC, n = 156; SPC without multiple side holes, n = 110; SPC with multiple side holes (SPC + M), n = 116). All patients showed shifting pleural effusions in the decubitus view of the chest radiography. All catheters were 10.2 Fr in diameter. One interventional radiologist performed all procedures and used the same anchoring technique. Complications (dysfunctional retraction, complete dislodgement, blockage, and atraumatic pneumothorax) were compared among the catheters using chi-square and Fisher's exact tests. Clinical success was defined as an improvement in pleural effusion within three days without additional procedures. Survival analysis was performed to calculate the indwelling time. Results: The dysfunctional retraction rate of DPC was significantly lower than that of the other catheters (p < 0.001). Complete dislodgement did not occur in any of the DPC cases. The clinical success rate of DPC (90.1%) was the highest. The estimated indwelling times were nine (95% confidence interval (CI): 7.3-10.7), eight (95% CI: 6.6-9.4), and seven (95% CI: 6.3-7.7) days for SPC, SPC + M, and DPC, respectively, with DPC showing a significant difference (p < 0.05). Conclusions: DPC had a lower dysfunctional retraction rate compared to conventional drainage catheters. Furthermore, DPC was efficient for pleural effusion drainage with a shorter indwelling time.

The Application of Pigtail Catheters in Postoperative Drainage of Lung Cancer

BACKGROUND

Although minimally invasive surgery has been widely carried out at present, the postoperative pain of patients with lung cancer is still one of the difficult problems to solve in clinical practice.

OBJECTIVE

This study explored whether indwelling pigtail catheters after lung cancer surgery can help to reduce postoperative pain and promote the recovery of patients as soon as possible.

MATERIALS AND METHODS

From June 2018 to June 2020, patients who underwent thoracoscopic radical resection of lung cancer in our hospital were randomly divided into 2 groups: the pigtail catheter group and the control group. We compared the postoperative time of thoracic catheter removal, postoperative pain score, proportion of postoperative pleural effusion, postoperative hospitalization time, and postoperative complications of the 2 groups.

RESULTS

A total of 1375 patients were enrolled, including 677 patients in the pigtail catheter group and 698 patients in the control group. Compared with the control group, the pigtail catheter group had an earlier time of thoracic catheter removal, lower postoperative pain score, lower proportion of pleural effusion diagnosed by postoperative chest radiograph, and shorter postoperative average hospital stay, but there was no significant difference in postoperative complications.

CONCLUSION

The application of pigtail catheters after radical resection of lung cancer can reduce postoperative pain, accelerate the recovery of patients and shorten the postoperative hospital stay and is safe and reliable in clinical application.

Comparison of clinical manifestation among Australian Indigenous and non- Indigenous patients presenting with pleural effusion

BACKGROUND

There is sparse evidence in the literature in relation to the nature and causes of pleural effusion among Australian Indigenous population.

METHODS

In this retrospective study, Indigenous and non-Indigenous adults diagnosed to have pleural effusion over a two-year study period were included for comparative analysis.

RESULTS

Of the 314 patients, 205 (65%) were non-Indigenous and 52% were males. In comparison to non-Indigenous, the Indigenous patients were younger (50 years (IQR 39,60) vs 63 years (IQR 52,72), p<0.001), females (61% vs 41%, p=0.001), have higher prevalence of renal and cardiovascular disease and tend to have exudative effusion (93% vs 76%, p=0.032). Infections was judged to be the most common cause for effusion in both groups, more so among the Indigenous cohort. Effusion secondary to renal disease was higher (13% vs 1%, p<0.001) among Indigenous Australians, in contrast malignant effusions were higher (13% vs 4%, p=0.004) among non-Indigenous. Length of hospital stay was longer for Indigenous patients (p=0.001), and a greater proportion received renal dialysis (13% vs 1%, p<0.001). Intensive care unit (ICU) admissions rates were higher with infective etiology of pleural effusion (82% vs. 53% Indigenous & 44% vs. 39% non-Indigenous respectively). Re-presentations to hospital were higher among Indigenous patients (46% vs 33%, p=0.046) and were associated with renal and cardiac disease and malignancy in non-Indigenous.

CONCLUSION

There are significant differences in the way pleural effusion manifests among Australian Indigenous patients. Understanding these differences may facilitate approaches to the management and to implement strategies to reduce morbidity and mortality in this population. This article is protected by copyright.
