Chronic peritoneal indwelling catheters for the management of malignant and nonmalignant ascites

Antibiotic administration via indwelling peritoneal catheter to treat infected malignant ascites

Indwelling pleural catheter is an established management for malignant pleural effusions. Extending its use to patients with malignant ascites by insertion of a catheter intraperitoneally enables regular outpatient drainage and improves quality-of-life. However, indwelling pleural/peritoneal catheter (IPC/IPeC) is associated with catheter-related infections, traditionally managed with systemic antibiotics and occasionally requires catheter removal. Direct administration of antibiotics intra-abdominally via peritoneal dialysis (PD) catheters is a well-established, efficacious practice in PD-related peritonitis and minimizes systemic adverse effects. We applied the same principles to a patient with peritoneal mesothelioma who developed peritonitis 3 weeks after insertion of IPeC. Intraperitoneal vancomycin was administered via, and compatible with, the IPeC. The patient tolerated the treatment without adverse effects and made a full recovery without requiring catheter removal.

Current treatment options of refractory ascites in liver cirrhosis - A systematic review and meta-analysis

BACKGROUND

Refractory ascites is a severe complication of liver cirrhosis and treatment options consist in large volume paracentesis, transjugular intrahepatic portosystemic shunt, alfapump®, peritoneovenous shunt and permanent indwelling peritoneal catheter.

AIM

Our aim was to assess the efficacy, mortality and complications of each treatment.

METHODS

We performed a systematic review using Pubmed and Embase. Frequencies were summarized with Comprehensive Meta-Analysis Software.

RESULTS

Seventy-seven studies were included. In patients with transjugular intrahepatic portosystemic shunt, 1-year mortality was 33% (95% CI 0.29-0.39, I²=82.1; τ² = 0.37; p<0.001) with lower mortality in newer studies (26% vs. 44%). At 6 months, mortality in patients with alfapump® was 24% (95% CI 0.16-0.33, I²=0.00; τ² = 0.00; p = 0.83), 31% developed acute kidney injury (95% CI 0.18-0.48, I²=44.0; τ² = 0.22; p = 0.15). Mortality at 12 months was 44% (95% CI 32%-58%, I²=76.7, τ² = 0.44, p<0.001) in peritoneovenous shunts and 45% (95% CI 38%-53%, I²=61.4, τ² = 0.18, p = 0.003) in large volume paracentesis, respectively. Overall mortality in patients with permanent indwelling catheters was 66% (95% CI 33%-89%, I²=82.5, τ² = 1.57, p = 0.001).

DISCUSSION

Mortality in patients with transjugular intrahepatic portosystemic shunt was lower in newer studies, probably due to a better patient selection. Acute kidney injury was frequent in patients with alfapump®. Permanent indwelling catheters seemed to be a good option in a palliative setting.

Long-Term Peritoneal Indwelling Catheters for Malignant Ascites: A Retrospective Case Series of PleurX and Peritoneal Port

Objectives: To compare outcomes of PleurX and peritoneal port for malignant ascites. Design: Retrospective review of medical records was conducted. Setting/Subjects: Subjects were consecutive patients receiving PleurX or peritoneal port for malignant ascites in a center in Sydney, Australia. Measurements: Demographic data, complication rates, hospitalization rates, and survival were measured. Results: Sixteen cases were analyzed: 6 had peritoneal port (170 catheter days) and 10 had PleurX (477 catheter days). Complication rates were low with both drainage systems. Cellulitis rate was 33% (1.2 events/100 catheter days) for peritoneal port and 10% (0.2 events/100 catheter days) for PleurX. Hospital admission days were 27 days/100 catheter days for peritoneal port and 5.2 days/100 catheter days for PleurX. Conclusions: Both PleurX and peritoneal port seem feasible options in draining malignant ascites. Further research is needed to ascertain whether there are true differences in cellulitis/admission rates. Patient quality of life, experience, and preference should be included in future studies.

Hospice care for end stage liver disease in the United States

INTRODUCTION

Patients with end-stage liver disease (ESLD) have impaired physical, psychological, and social functions, which can diminish patient quality of life, burden family caregivers, and increase health-care utilization. For those with a life expectancy of less than six months, these impairments and their downstream effects can be addressed effectively through high-quality hospice care, delivered by multidisciplinary teams and focused on the physical, emotional, social, and spiritual wellbeing of patients and caregivers, with a goal of improving quality of life.

AREAS COVERED

In this review, we examine the evidence supporting hospice for ESLD, we compare this evidence to that supporting hospice more broadly, and we identify potential criteria that may be useful in determining hospice appropriateness.

EXPERT OPINION

Despite the potential for hospice to improve care for those at the end of life, it is underutilized for patients with ESLD. Increasing the appropriate utilization of hospice for ESLD requires a better understanding of patient eligibility, which can be based on predictors of high short-term mortality and liver transplant ineligibility. Such hospice criteria should be data-driven and should accommodate the uncertainty faced by patients and physicians.

Imaging of abdominal and pelvic infections in the cancer patient

Infections are the most commonly encountered complications in patients with cancer. The classical signs and symptoms of infections are often not present in this patient population, which makes the diagnosis more challenging. Host factors play a major role in the development and prognosis of infections in cancer patients; these can be related to the underlying type of malignancy (solid organ versus hematological), tumor burden, anatomic obstruction, altered integrity of barriers (skin or mucosa), treatment-related factors (from chemotherapy, radiation treatment, surgery, interventional procedures, and/or medical device placement) and the degree of immunosuppression. This article reviews common, as well as less common, imaging manifestations of infections and their potential mimics in the abdomen and pelvis in cancer patients and discusses their differentiating features, with the role of imaging in various organs in the abdomen and pelvis taking into consideration relevant clinical background information and the main risk factors.

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.

Guidelines on the management of ascites in cirrhosis

The British Society of Gastroenterology in collaboration with British Association for the Study of the Liver has prepared this document. The aim of this guideline is to review and summarise the evidence that guides clinical diagnosis and management of ascites in patients with cirrhosis. Substantial advances have been made in this area since the publication of the last guideline in 2007. These guidelines are based on a comprehensive literature search and comprise systematic reviews in the key areas, including the diagnostic tests, diuretic use, therapeutic paracentesis, use of albumin, transjugular intrahepatic portosystemic stent shunt, spontaneous bacterial peritonitis and beta-blockers in patients with ascites. Where recent systematic reviews and meta-analysis are available, these have been updated with additional studies. In addition, the results of prospective and retrospective studies, evidence obtained from expert committee reports and, in some instances, reports from case series have been included. Where possible, judgement has been made on the quality of information used to generate the guidelines and the specific recommendations have been made according to the 'Grading of Recommendations Assessment, Development and Evaluation (GRADE)' system. These guidelines are intended to inform practising clinicians, and it is expected that these guidelines will be revised in 3 years' time.

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.

Use of Peritoneal Catheters for Patients Receiving Palliative Care

Background: Recurrent ascites is a late manifestation of several diseases, including cancer, cirrhosis, and heart failure, invariably associated with very poor prognosis. Hence, every effort must be aimed at reducing discomfort and side effects of its management. Objective: To evaluate if peritoneal catheters (PCs) are a viable alternative treatment approach in palliative patients who fail medical management of ascites. Design: Case study. Results: We report the case of a terminal patient with cirrhosis and hepatocellular carcinoma who presented refractory ascites despite serial large-volume paracentesis. A Tenckhoff percutaneous catheter was inserted, allowing for ascites' control and with no complications noted. Conclusions: PC placement was successful in controlling the patient's symptoms and ultimately improved comfort and well-being during the final stage of his life. This option should be assessed in selected patients to elevate palliative standards of care.

Drenaje peritoneal como tratamiento de la ascitis maligna, una revisión de la literatura

Introducción: La ascitis maligna es la acumulación anormal de fluido en la cavidad peritoneal como consecuencia de patologías como el cáncer, además es un factor desencadenante de clúster de síntomas (dolor, disnea, pérdida de apetito, náuseas, reducción a la movilidad y cambios en el aspecto físico) que se convierten en un problema clínico de difícil manejo. Dentro de los tratamientos encaminados al mejoramiento de esta condición se encuentra la paracentesis terapéutica, procedimiento médico cuya técnica se hace mediante drenaje y que en ocasiones se requiere practicar de manera repetitiva, pudiendo ser un síntoma refractario que conlleva al requerimiento de la implantación de un catéter peritoneal como una medida paliativa para el mejoramiento de la calidad de vida del paciente y su familia. Materiales y Métodos: Se realiza una revisión de la literatura existente, estableciéndose una búsqueda inicial donde se obtuvieron 747 artículos de los cuales se incluyen 277 potencialmente relevantes, a los que se le verificaron el cumplimiento de los criterios de inclusión, y posterior a la depuración de la información y de eliminar artículos duplicados y se incluyeron en la revisión los 8 estudios que cumplieron la totalidad de estos parámetros. Resultados: La técnica del catéter peritoneal es 100% exitosa, no presenta complicaciones inmediatas, óptima medida paliativa para los pacientes con ascitis refractaria permitiendo más de 30 días de durabilidad del dispositivo, además, de un fácil uso por profesionales, paciente y familia, permitiendo un manejo ambulatorio que disminuye costos, reingresos por complicaciones tardías potencialmente prevenibles e identificables como lo son filtración, desplazamiento, infecciones, oclusión del dispositivo hospitalarios y proporcionando confort y control de síntomas de manera inmediata. Discusión y Conclusiones: Con los resultados expuestos en la presente revisión se define el catéter peritoneal óptimo en el manejo de la ascitis maligna como medida paliativa. En el tratamiento de esta y de los demás síntomas desencadenados en pacientes con patologías oncológicas avanzadas, permitiendo un mejoramiento en la calidad de vida de las personas.

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.

[Ascites]

Ascites is the most common cause of decompensation in cirrhosis, and 5% to 10% of patients with compensated cirrhosis develop ascites each year. The main factor of ascites formation is renal sodium retention due to activation of the renin-angiotensin-aldosterone system and sympathetic nervous system by the reduced effective volume secondary to splanchnic arterial vasodilation. Diagnostic paracentesis is indicated in all patients with a new onset of grade 2 or 3 ascites and in those admitted to hospital for any complication of cirrhosis. A serum-ascites albumin gradient of ≥1.1 g/dL indicates portal hypertension with an accuracy of approximately 97%. Sodium restriction, diuretics, and large volume paracentesis are the mainstay of treatment in grade 1 to 3 ascites. The refractoriness of ascites is associated with a poor prognosis with a median survival of approximately six months. Repeated large volume paracentesis plus albumin is the first line treatment, and liver transplantation is recommended in patients with refractory ascites. A careful selection of patients is also important to obtain the beneficial effects of transjugular intrahepatic portosystemic shunts in refractory ascites. This review details the recent diagnosis and treatment of cirrhotic ascites.
