Peritoneal and pleural ports for management of refractory ascites and pleural effusions: assessment of impact on patient quality of life and hospice/home nursing care

Safety and Prognostic Factor for Survival in Patients with PleurX Drain for Malignant Ascites: AscitX Study

Background: Malignant ascites (MA) represents 10% of all causes of ascites and is associated with a poor prognosis. The PleurX tunneled peritoneal catheter is a device that allows the management of MA at home in a palliative care context (renamed AscitX catheter for this work). The objective of this study was to analyze real-world data of AscitX use for cancer patients with MA, to describe complications associated with the insertion of this device, and to identify factors influencing patient outcomes. Methods: Fifty-six patients with AscitX catheter insertion between October 2018 and October 2022 in our comprehensive cancer center were retrospectively analyzed. Computed tomography (CT) scans were reviewed by two radiologists to determine the presence of liver and peritoneal metastases and to identify portal hypertension. Results: The majority of patients were followed for pancreatic cancer (39%), followed by ovarian cancer (18%). We identified four cases of severe infections post-insertion and two moderate infections. The median survival time after AscitX insertion was 18 days. A Kaplan-Meier analysis did not identify differences in survival time between patients with peritoneal metastases and those with liver metastases. In contrast, CT-diagnosed portal hypertension and the absence of diuretic treatment were independently associated with a better prognosis. Regarding post-catheter end-of-life management, 41% of the patients died at home. Conclusions: AscitX catheter safety appears to be acceptable and most of the palliative care patients included in our study died at home. We identified CT-diagnosed portal hypertension as associated with better prognosis, as well as the absence of diuretic treatment.

Tunneled Peritoneal Catheter vs Repeated Paracenteses for Recurrent Ascites: A Cost-Effectiveness Analysis

PURPOSE

To compare the cost-effectiveness of tunneled peritoneal catheter (TPC) versus serial large-volume paracenteses (LVP) for patients with recurrent ascites.

MATERIALS AND METHODS

Retrospective, single-institution analysis of 100 consecutive patients undergoing LVP and eventual TPC placement (2015-2018) was performed with extraction of procedural complications and hospital admissions. LVPs were associated with 17 adverse events (AEs) while only 9 AEs occurred after TPC placement. While undergoing routine LVP, the patients had 30 hospitalizations monthly (177 days in total) and 10 hospitalizations monthly (51 days) after TPC placement. A cost-effectiveness analysis with Markov modeling was performed comparing TPC and LVP. Costs were based on Medicare reimbursement rates. Statistical analyses include base case calculation, Monte Carlo simulations, and deterministic sensitivity analyses.

RESULTS

TPC placement was the dominant strategy with a comparable health benefit of 0.08060 quality-adjusted life-years (QALY) (LVP: 0.08057 QALY) at a lower cost of $4151 (LVP: $8401). Probabilistic sensitivity analysis showed TPC was superior in 97.49% of simulations. Deterministic sensitivity analysis demonstrated the superiority of TPC compared to LVP if the TPC complication rate was < 9.47% per week and the complication rate for LVP was > 1.32% per procedure. TPC was more cost-effective when its procedural cost was < $5427 (base case: 1174.5), and remained as such when the cost of LVP was varied as much as $10,000 (base case: $316.48).

CONCLUSION

In this study, TPC was more cost-effective than LVP in patients with recurrent ascites due to the reduced risk of infection, emergency department visits, and length of hospitalization stays.

Management of Refractory Ascites Due to Portal Hypertension: Current Status

Refractory ascites is a costly and debilitating condition that occurs most frequently in the setting of substantial cirrhotic portal hypertension, where it portends a poor prognosis. Many treatment options are available, among them medical management, serial large volume paracenteses, transjugular intrahepatic portosystemic shunts, and implanted drainage devices. Although the availability of multiple therapies ensures that most patients will achieve satisfactory results, it can be challenging for the provider to select the appropriate treatment for each specific patient. This article reviews the available therapeutic options for refractory ascites and incorporates available data and clinical experience to suggest a linear stepwise management approach to enhance patient outcomes.

Palliative Paracentesis in the Home Setting: A Case Series

BACKGROUND

Management of ascites-related symptoms in home hospice and palliative care patients can be challenging. Ultrasound-guided paracentesis is a standard intervention for this indication, but generally requires transfer to a hospital or outpatient interventional-radiology (IR) setting; thus, such interventions are often not practical or attainable for home hospice and palliative care patients.

OBJECTIVE

To describe a mobile, in-home service that provides home-based palliative paracentesis (HBPP) as an interventional palliative option for patients with distressing symptoms related to ascites.

DESIGN

Retrospective case series. Setting/Subjects: Thirty patients with ascites, confirmed by portable bedside ultrasound, who underwent HBPP at their residence.

RESULTS

Thirty-three patients were referred for HBPP for symptomatic abdominal distention from March 1, 2019 to March 1, 2020. Thirty (91%) patients had ultrasound-confirmed ascites and received HBPP. All 30, verbalized appreciable symptom relief post-intervention. There were no reported post-procedural complications.

CONCLUSION

Home-based palliative paracentesis is a safe, effective, and convenient intervention for hospice and palliative care patients with symptomatic ascites.

Peritoneal Dialysis Catheters to Treat Refractory Non-Malignant Ascites

Refractory non-malignant ascites is associated with significant morbidity. Serial, large-volume paracentesis is a common treatment. Tunneled peritoneal dialysis (PD) catheters are an effective treatment for refractory malignant ascites, but there are limited data on complications and effectiveness for non-malignant ascites. We reviewed all 13 PD catheter insertions between 2010 - 2015 for this indication at our center. The median catheter survival time was 146 days. No complications occurred during catheter insertion, and no mechanical complications occurred after catheter insertion. One case of peritonitis developed over 217 catheter months. Peritoneal dialysis catheters may be a safe and effective option to manage refractory non-malignant ascites. Prospective, randomized trials are needed to better evaluate potential risks and benefits.

Permanent indwelling peritoneal catheters for palliation of refractory ascites in end-stage liver disease: A systematic review

BACKGROUND & AIMS

The incidence and mortality from end-stage liver disease is increasing, with a minority eligible for liver transplantation. Ascites is the commonest complication of end-stage liver disease and large volume paracentesis (LVP) the accepted management strategy where refractory to medical treatment. In malignant ascites, permanent indwelling peritoneal catheters (PIPC) are an established palliative intervention. The aims are to describe available data using permanent indwelling peritoneal catheters in refractory ascites due to end-stage liver disease.

METHODS

Using systematic review methodology, databases were searched (MEDLINE, EMBASE, CINAHL [The Cumulative Index to Nursing and Allied Health Literature], Google Scholar and Cochrane Database of Systematic Reviews from inception-March 2018), for studies combining ascites and palliative care. Inclusion and exclusion criteria were applied to results.

RESULTS

Following initial and updated searches, 225 studies were identified for full text review, 18 were eligible for final analysis. The studies displayed heterogeneity in design, reported on different indwelling catheters and were overall of low quality. Only one pilot randomised controlled trial was identified, of PIPC versus LVP, recruiting one patient into each arm. Technical insertion success was 100%, with low rates of non-infectious complications (<12%), none life threatening. Rates of bacterial peritonitis were not unacceptably high (12.7%), considering this was an end-stage liver disease population and only a minority utilising long-term prophylactic antibiotics. Only one study attempted quality-of-life assessments; none addressed potential health economic benefits.

CONCLUSIONS

Despite lack of well-designed studies, preliminary data suggests low significant complication rates; however safety and efficacy of permanent indwelling peritoneal catheters in end-stage liver disease remains to be confirmed. Further prospective randomised controlled trials are warranted, potentially translating permanent indwelling peritoneal catheters into improved palliative care in end-stage liver disease.

Quality of life improves after palliative placement of percutaneous tunneled drainage catheter for refractory ascites in prospective study of patients with end-stage cancer

OBJECTIVE

Percutaneous tunneled drainage catheter (PTDC) placement is a palliative alternative to serial paracenteses in patients with end-stage cancer and refractory ascites. The impact of PTDC on quality of life (QoL) and long-term outcomes has not been prospectively described. The objective was to evaluate changes in QoL after PTDC.

METHOD

Eligible adult patients with end-stage cancer undergoing PTDC placement for refractory ascites completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire and McGill Quality of Life instruments before PTDC placement and at 2 to 7 days and 2 to 4 weeks after PTDC. Catheter function, complications, and laboratory values were assessed. Analysis of QoL data was evaluated with a stratified Wilcoxon signed-rank test.

RESULT

Fifty patients enrolled. Survey completion ranged from 65% to 100% (median 88%) across timepoints. All patients had a Tenckhoff catheter, with 98% technical success. Median survival after PTDC was 38 days (95% confidence interval = 32, 57 days). European Organization for Research and Treatment of Cancer scores showed improvement in global QoL (p = 0.03) at 1 week postprocedure (PP). Significant symptom improvement was reported for fatigue, nausea/vomiting, pain, dyspnea, insomnia, and appetite at 1 week PP and was sustained at 3 weeks PP for dyspnea (p < 0.01), insomnia (p < 0.01), and appetite loss (p = 0.03). McGill Quality of Life demonstrated overall QoL improvement at 1 (p = 0.03) and 3 weeks (p = 0.04) PP. Decline in sodium and albumin values pre- and post-PTDC slowed significantly (albumin slope -0.43 to -0.26, p = 0.055; sodium slope -2.50 to 1.31, p = 0.04). Creatinine values increased at an accelerated pace post-PTDC (0.040 to 0.21, p < 0.01). Thirty-eight catheter-related complications occurred in 24 of 45 patients (53%).

SIGNIFICANCE OF RESULTS

QoL and symptoms improved after PTDC placement for refractory ascites in patients with end-stage malignancy. Decline in sodium and albumin values slowed postplacement. This study supports the use of a PTDC for palliation of refractory ascites in cancer patients.

Permanent peritoneal ports for the management of recurrent malignant ascites: a retrospective review of safety and efficacy

Large volume paracentesis is effective in relieving the symptoms of malignant ascites, but frequent procedures are often required. Permanent peritoneal ports are an alternative to repeated procedures. We describe our experience with the use of peritoneal ports in patients at Middlemore Hospital (Auckland, New Zealand) who had a port inserted for the drainage of malignant ascites. Twenty-eight ports were inserted in 26 patients and accessed a total of 257 times with acceptably low rates of complications including cellulitis, peritonitis and wound dehiscence.

Incorporating Quality of Life Metrics in Interventional Oncology Practice

Interventional radiologists care for a large number of cancer patients with the breadth of palliative intent minimally invasive procedures that we provide. Understanding our meaningful impact on patients' quality of life is essential toward validating our role in the palliation of cancer patients. As such, it is critically important for interventional radiologists to understand common instruments used for the reporting of patient's quality of life measures. Common instruments used to measure pain and quality of life for cancer patients include the numerical rating scale, visual analog scale, brief pain inventory, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, and the Functional Assessment of Cancer Therapy. An ideal quality of life instrument should be a patient reported outcome measure across multiple domains (e.g., physical health, psychological, social), and be both validated and reliable.

Symptomatic Fluid Drainage: Tunneled Peritoneal and Pleural Catheters

Malignant ascites and pleural effusion are significant contributors to patient symptoms such as shortness of breath, abdominal distension, and nausea in the setting of cancer. There are numerous methods employed to control such symptoms such as serial drainages, pleurodesis, and tunneled drainage catheters. Tunneled drainage catheters are a safe, effective, and a minimally invasive procedure to palliate the symptoms of malignant ascites and pleural effusion.

Drainage of malignant ascites: patient selection and perspectives

Malignant ascites (MA) is a sign of advanced cancer and poor prognosis. MA can result in impairment in quality of life (QOL) and significant symptoms. As a supportive treatment, ascites can be drained by paracentesis (PC), percutaneously implanted catheters (tunneled, untunneled, central venous catheters), or peritoneal ports, or peritoneovenous shunts. The aim of this study was to evaluate the effectiveness, safety, and patient-reported outcomes (PRO) of different drainage methods for the management of MA. A systematic review of the literature was performed, and 32 original articles met the inclusion criteria. Patients selected for permanent drain insertion demonstrated symptoms related to MA and had undergone repeated PC. The primary focus of the reviewed articles was procedural safety issues. The rate of technical success of drainage device installation was 100%. Most patients experienced improvements in symptom control after ascites drainage. When analyzed together, 19.7% (255/1297) of patients experienced any complication and 6.2% (81/1297) experienced serious adverse events during MA drainage. Complications were reported for every drainage method; however, the least occurred after PC or central venous catheter, while the most serious occurred after peritoneovenous shunts. Adverse events were as follows: catheter obstruction: 4.4%, infection: 4.1%, leakage: 3.5%, catheter dislodgment: 2.3%, hypotension: 0.6%, injuries during device insertion: 0.6%, renal impairment: 0.5%, electrolyte imbalance: 0.2%, other: 3.6%. PRO and QOL endpoints were available for 12 studies. When PRO were measured using an interview, a significant improvement in symptom control and QOL was reported in almost all patients. Once standardized questionnaires were used, improvements in symptomatic scores and role functioning were observed. Deterioration was observed in cognitive and emotional subscales. MA drainage is a safe and effective method to control symptoms associated with ascites, and should be perceived as a supportive care, that can be applied for those who need it at any time of their cancer trajectory. Patient selection should be performed using a thorough assessment of symptoms and QOL, and should not be delayed.

Permanent catheters for recurrent ascites-a critical and systematic review of study methodology

PURPOSE

Management of refractory ascites traditionally includes medical treatment with diuretics or intermittent paracentesis. Patients with recurrent ascites may benefit from the use of permanent intra-abdominal catheters with more frequent drainage without hospitalization. The objective was to systematically asses the methodology of factors and endpoints reported in studies investigating permanent catheters for recurrent ascites treatment.

METHODS

Using a systematic search strategy, we critically assessed the methodology when treating refractory ascites using a permanent catheter. Studies critically assessed included both retro- and prospective studies.

RESULTS

A total of 715 unique articles were found via PubMed, The Cochrane Library and Embase. Twenty-nine studies (tunnelled catheter = 12, peritoneal ports = 6 and peritoneovenous shunts = 11) with three distinct types of permanent catheters fulfilled the inclusion criteria. Only three studies reported technical success less than 100 %. Data on complications and treatment were not available in all papers; peritonitis (48 %), cellulitis (41 %), prophylactic antibiotics (48 %) and complications to catheter insertion were difficult to distinguish from advanced co-morbidity of patients. Thirteen studies (45 %) reported some type of evaluating patient experience or functional outcome, but only three studies used validated reproducible scales when assessing outcomes. Fifteen of the 29 studies included 30 patients or less.

CONCLUSION

Knowledge is limited because complications and outcomes are poorly defined. The expected increase in catheter treatment of refractory ascites necessitates comparative studies, using validated patient-related outcomes, and the reporting of unambiguous complications. A proposal of variables to include in future studies is presented.

Successful use of indwelling tunneled catheters for the management of effusions in children with advanced cancer

BACKGROUND

Malignant pleural effusion (MPE) and ascites (MA) negatively impact quality of life of palliative patients. Treatment options are limited. This study's purpose is to examine the experience with indwelling tunneled catheters (ITCs) for management of MPE/MA in children with advanced cancer.

METHODS

Children with MPE/MA who underwent ITC insertion (2007-2012) were retrospectively reviewed. Clinical, procedural, complication and outcome details were analyzed.

RESULTS

PleurX® ITCs (n = 12) were inserted in eight patients (5-18 years) with sarcoma (11 MPE, 1 MA), achieving symptom relief and facilitating discharge home post ITC (median 2 days). Median survival following ITC was 51 days. There were two major complications: pain (n = 1), late site infection (n = 1), and five minor complications. Drainage ceased in four patients (pleurodesis/tumor progression). At time of death, six ITCs (five patients) were still in situ.

CONCLUSIONS

ITC appears to be a safe, effective treatment for MPE/MA in advanced pediatric cancer, achieving symptomatic relief and discharge home.

Quality-of-Life assessment in malignant pleural effusion treated with indwelling pleural catheter: a prospective study

BACKGROUND

Malignant pleural effusion is a clinical problem that impairs Quality of Life in patients with advanced malignancies. An indwelling pleural catheter is an alternative treatment to palliate some of the symptoms.

AIM

To evaluate the Quality of Life of outpatients with malignant pleural effusion who were treated with an indwelling pleural catheter. Questionnaire compliance, catheter patency time, and survival were analyzed.

DESIGN

A multicenter observational study was conducted across five hospitals in Spain. Quality of Life was assessed at three different time points (before catheter placement and at 30 and 60 days post-placement) using the European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire QLQ-C30. For lung cancer patients, the QLQ-LC13 was also used.

PARTICIPANTS

Patients with recurrent malignant pleural effusion treated with an indwelling pleural catheter.

RESULTS

A total of 51 outpatients completed the baseline QLQ-C30 questionnaire. Of these, 28 completed the questionnaire at 30 days. Of these 28 patients, 13 completed the questionnaire at 60 days. Scores showed a significant improvement in symptoms scales at 30 days (p = 0.03). Global health status and functional scales showed a non-significant trend to improvement at 30 and 60 days. A total of 27 lung cancer patients completed the QLQ-LC13 questionnaire. Items assessing dyspnea showed a significant improvement following catheter placement (p = 0.002).

CONCLUSION

Indwelling pleural catheter is useful for palliative management of recurrent malignant pleural effusion in that it benefits Quality of Life in outpatients with advanced malignancies. In lung cancer patients, scores indicated that indwelling pleural catheter also provides significant relief of dyspnea.

Interventional radiology in paediatric palliative care

Paediatric palliative care is a distinct subspecialty that offers treatment to children with many types of illness, including oncological, neurological and respiratory problems. Paediatric interventional radiologists can make a useful contribution to symptom management as part of a multidisciplinary team. Interventions for pain management include local ablation or other treatment of painful lesions, image-guided nerve blocks and the insertion of devices for the delivery of analgesic drugs. Various techniques are also available for the management of ascites, pleural effusions and other symptomatic complications of the underlying disease process.

Outcomes of permanent peritoneal ports for the management of recurrent malignant ascites

BACKGROUND AND OBJECTIVE

Ascites complicates many advanced malignancies, resulting in abdominal pain, discomfort, anorexia, nausea, and dyspnea. Percutaneous drainage relieves symptoms in the vast majority of patients. The aim of this study was to determine the course and outcomes in a consecutive series of patients with recurrent ascites managed with permanent peritoneal ports.

METHODS

A prospective longitudinal descriptive study from 2006 to 2011, involving patients treated at the Sydney Cancer Center (New South Wales, Australia).

RESULTS AND CONCLUSIONS

A total of 155 drainages were performed in 24 patients; 26% of drainages (n=40) in the patient's home and the remainder in the ambulatory care clinic. Grade 3 or higher adverse events occured in less than 25% of all draining procedures. An improvement in symptoms was demonstrated in almost half of all individual drainage procedures. Our findings suggest that peritoneal ports are efficacious, safe, and are associated with symptomatic relief in most patients.

Quality-of-life assessment after palliative interventions to manage malignant ureteral obstruction

PURPOSE

Malignancies may cause urinary tract obstruction, which is often relieved with placement of a percutaneous nephrostomy tube, an internal double J nephro-ureteric stent (double J), or an internal external nephroureteral stent (NUS). We evaluated the affect of these palliative interventions on quality of life (QoL) using previously validated surveys.

METHODS

Forty-six patients with malignancy related ureteral obstruction received nephrostomy tubes (n = 16), double J stents (n = 15), or NUS (n = 15) as determined by a multidisciplinary team. QoL surveys were administered at 7, 30, and 90 days after the palliative procedure to evaluate symptoms and physical, social, functional, and emotional well-being. Number of related procedures, fluoroscopy time, and complications were documented. Kruskal-Wallis and Friedman's test were used to compare patients at 7, 30, and 90 days. Spearman's rank correlation coefficient was used to assess correlations between clinical outcomes/symptoms and QoL.

RESULTS

Responses to QoL surveys were not significantly different for patients receiving nephrostomies, double J stents, or NUS at 7, 30, or 90 days. At 30 and 90 days there were significantly higher reported urinary symptoms and pain in those receiving double J stents compared with nephrostomies (P = 0.0035 and P = 0.0189, respectively). Significantly greater fluoroscopy time was needed for double J stent-related procedures (P = 0.0054). Nephrostomy tubes were associated with more frequent minor complications requiring additional changes.

CONCLUSION

QoL was not significantly different. However, a greater incidence of pain in those receiving double J stents and more frequent tube changes in those with nephrostomy tubes should be considered when choosing palliative approaches.

Reporting of "quality of life": a systematic review and quantitative analysis of research publications in palliative care journals

CONTEXT

Palliative care clinical practice depends upon an evidence-based decision-making process which in turn is based upon current research evidence. One of the most important goals in clinical palliative care is to improve patients' quality of life (QoL).

AIM

This study aimed to perform a quantitative analysis of research publications in palliative care journals for reporting characteristics of articles on QoL.

SETTINGS AND DESIGN

This was a systematic review of palliative care journals.

MATERIALS AND METHODS

Twelve palliative care journals were searched for articles with "QoL" in the title of the articles published from 2006 to 2010. The reporting rates of all journals were compared. The selected articles were categorized into assessment and treatment, and subsequently grouped into original and review articles. The original articles were subgrouped into qualitative and quantitative studies, and the review articles were grouped into narrative and systematic reviews. Each subgroup of original article category was further classified according to study designs.

STATISTICAL ANALYSIS USED

Descriptive analysis using frequencies and percentiles was done using SPSS for Windows, version 11.5.

RESULTS

The overall reporting rate among all journals was 1.95% (71/3634), and Indian Journal of Palliative Care (IJPC) had the highest reporting rate of 5.08% (3/59), followed by Palliative Medicine (PM) with 3.71% (20/538), and Palliative and Supportive Care (PSC) with 3.64% (9/247) reporting.

CONCLUSIONS

The overall reporting rate for QoL articles in palliative care journals was 1.95% and there were very few randomized clinical trials and systematic reviews found. The study findings indicate further high-quality research to establish an adequate evidence base for QoL.

Dyspnea review for the palliative care professional: treatment goals and therapeutic options

Although dyspnea is frequently encountered in the palliative care setting, its optimal management remains uncertain. Clinical approaches begin with accurate assessment, as delineated in part one of this two-part series. Comprehensive dyspnea assessment, which encompasses the physical, emotional, social, and spiritual aspects of this complex symptom, guide the clinician in choosing therapeutic approaches herein presented as part two. Global management of dyspnea is appropriate both as complementary to disease-targeted treatments that target the underlying etiology, and as the sole focus when the symptom has become intractable, disease is maximally treated, and goals of care shift to comfort and quality of life. In this setting, current evidence supports the use of oral or parenteral opioids as the mainstay of dyspnea management, and of inhaled furosemide and anxiolytics as adjuncts. Nonpharmacologic interventions such as acupuncture and pulmonary rehabilitation have potential effectiveness, although further research is needed, and use of a simple fan warrants consideration given its potential benefit and minimal burden and cost.

Use of the PleuralPort device for management of pleural effusion in six dogs and four cats

OBJECTIVE

To describe the placement technique, complications, and outcomes associated with use of the PleuralPort device for management of pleural effusion in dogs and cats.

STUDY DESIGN

Case Series.

ANIMALS

Six dogs and 4 cats.

METHODS

Medical records of all animals with pleural effusion managed with the PleuralPort device were reviewed. Data regarding signalment, fluid analysis, placement technique, duration of function, duration of implantation, complications, and outcome were collected. Owners and referring veterinarians were contacted for follow-up information.

RESULTS

Nine animals had chylous effusion and 1 dog had pleural carcinomatosis. Eleven ports were placed with 1 cat receiving bilateral ports. Four animals developed complications. One cat developed pneumothorax immediately after implantation and was euthanatized. In 2 dogs and 1 cat, the ports obstructed. The 6 remaining animals had functioning ports at time of death or resolution of effusion and no longer required use of the port. No significant port migration, irritation, or infection of the device was reported. Excluding the cat with pneumothorax, median duration of port function was 20 days (range 1-391), and median duration of port implantation was 391 days (range 6-723).

CONCLUSIONS

The PleuralPort device is a feasible option for the management of pleural effusion in dogs and cats.
