Outcomes of patients with chest tube insertion for hepatic hydrothorax

Hepatic hydrothorax

Hepatic hydrothorax (HH) refers to the presence of a pleural effusion that develops in the context of underlying liver cirrhosis and portal hypertension. It carries a high risk of morbidity and mortality, with a median survival of 8-12 months. Diagnosis is usually confirmed by pleural aspiration, demonstrating typical features of a transudative effusion in the absence of co-existent cardio-pulmonary or renal pathology. The clinical presentation is quite variable, with some patients remaining relatively asymptomatic in the presence of small or incidental effusions, while others present with frank respiratory failure requiring pleural intervention. The development of spontaneous bacterial empyema (SBEM) is a significant and not infrequent complication, requiring prompt recognition and treatment. While the mainstay of management is focused on optimising fluid balance through dietary salt restriction and diuretic therapy, liver transplantation remains the definitive treatment option. As such, it is crucial to adopt a multi-disciplinary approach-involving pulmonologists, hepatologists, dieticians, and palliative care physicians-in order to optimise care for this often complex group of patients. This review will discuss the basic pathophysiology of HH, its clinical presentation and diagnosis, as well as the approach to management of HH in clinical practice, focussing on both interventional and non-interventional treatment modalities.

International survey among hepatologists and pulmonologists on the hepatic hydrothorax: plea for recommendations

BACKGROUND

The Hepatic hydrothorax is a pleural effusion related to portal hypertension; its diagnosis and therapeutic management may be difficult. The aims of this article are which follows: To gather the practices of hepatogastroenterologists or pulmonologists practitioners regarding the diagnosis and management of the hepatic hydrothorax.

METHODS

Practitioners from 13 French- speaking countries were invited to answer an online questionnaire on the hepatic hydrothorax diagnosis and its management.

RESULTS

Five hundred twenty-eight practitioners (80% from France) responded to this survey. 75% were hepatogastroenterologists, 20% pulmonologists and the remaining 5% belonged to other specialities. The Hepatic hydrothorax can be located on the left lung for 64% of the responders (66% hepatogastroenterologists vs 57% pulmonologists; p = 0.25); The Hepatic hydrothorax can exist in the absence of clinical ascites for 91% of the responders (93% hepatogastroenterologists vs 88% pulmonologists; p = 0.27). An Ultrasound pleural scanning was systematically performed before a puncture for 43% of the responders (36% hepatogastroenterologists vs 70% pulmonologists; p < 0.001). A chest X-ray was performed before a puncture for 73% of the respondeurs (79% hepatogastroenterologists vs 54% pulmonologists; p < 0.001). In case of a spontaneous bacterial empyema, an albumin infusion was used by 73% hepatogastroenterologists and 20% pulmonologists (p < 0.001). A drain was used by 37% of the responders (37% hepatogastroenterologists vs 31% pulmonologists; p = 0.26).An Indwelling pleural catheter was used by 50% pulmonologists and 22% hepatogastroenterologists (p < 0.01). TIPS was recommended by 78% of the responders (85% hepatogastroenterologists vs 52% pulmonologists; p < 0.001) and a liver transplantation, by 76% of the responders (86% hepatogastroenterologists vs 44% pulmonologists; p < 0.001).

CONCLUSIONS

The results of this large study provide important data on practices of French speaking hepatogastroenterologists and pulmonologists; it appears that recommendations are warranted.

Pulmonary Assessment of the Liver Transplant Recipient

Respiratory symptoms and hypoxemia can complicate chronic liver disease and portal hypertension. Various pulmonary disorders affecting the pleura, lung parenchyma, and pulmonary vasculature are seen in end-stage liver disease, complicating liver transplantation (LT). Approximately 8% of cirrhotic patients in an intensive care unit develop severe pulmonary problems. These disorders affect waiting list mortality and posttransplant outcomes. A thorough history, physical examination, and appropriate laboratory tests help diagnose and assess the severity to risk stratify pulmonary diseases before LT. Hepatopulmonary syndrome (HPS), portopulmonary hypertension (POPH), and hepatic hydrothorax (HH) are respiratory consequences specific to cirrhosis and portal hypertension. HPS is seen in 5-30% of cirrhosis cases and is characterized by impaired oxygenation due to intrapulmonary vascular dilatations and arteriovenous shunts. Severe HPS is an indication of LT. The majority of patients with HPS resolve their hypoxemia after LT. When pulmonary arterial hypertension occurs in patients with portal hypertension, it is called POPH. All other causes of pulmonary arterial hypertension should be ruled out before labeling as POPH. Since severe POPH (mean pulmonary artery pressure [mPAP] >50 mm Hg) is a relative contraindication for LT, it is crucial to screen for POPH before LT. Those with moderate POPH (mPAP >35 mm Hg), who improve with medical therapy, will benefit from LT. A transudative pleural effusion called hepatic hydrothorax (HH) is seen in 5-10% of people with cirrhosis. Refractory cases of HH benefit from LT. In recent years, increasing clinical expertise and advances in the medical field have resulted in better outcomes in patients with moderate to severe pulmonary disorders, who undergo LT.

Austrian consensus on the diagnosis and management of portal hypertension in advanced chronic liver disease (Billroth IV)

The Billroth IV consensus was developed during a consensus meeting of the Austrian Society of Gastroenterology and Hepatology (ÖGGH) and the Austrian Society of Interventional Radiology (ÖGIR) held on the 26th of November 2022 in Vienna.Based on international recommendations and considering recent landmark studies, the Billroth IV consensus provides guidance regarding the diagnosis and management of portal hypertension in advanced chronic liver disease.

Refractory Hepatic Hydrothorax Is an Independent Predictor of Mortality When Compared to Refractory Ascites

BACKGROUND

Hepatic hydrothorax (HHT) is an uncommon but significant complication of cirrhosis and portal hypertension, associated with a worse prognosis and mortality. Nearly 25% of patients with HHT will have refractory pleural effusion. It is unclear if refractory HHT has a different prognosis compared to refractory ascites.

AIMS

We aim to evaluate the prognostic significance of refractory HHT when compared to refractory ascites.

METHODS

Forty-seven patients who had refractory HHT in a tertiary care center were identified, and matched, retrospectively, one-to-one by age, gender and MELD-Na with 47 patients with refractory ascites. One-year mortality rate was compared between both groups. Cox proportional hazard regression was used to identify the association between different covariates and primary endpoint.

RESULTS

The 1-year mortality was 51.06% in the HHT group compared to 19.15% in the refractory ascites group. The median survival for patients with refractory hepatic hydrothorax was 4.87 months while the median survival for patients with refractory ascites exceeded 1 year. The presence of HHT was statistically significant in predicting the development of 1-year mortality [Hazard Ratio (HR) 4.45, 95% Confidence Interval (CI) 2.25-8.82; P value < 0.001]. Furthermore, refractory HHT remained associated with one-year mortality after adjusting for all other covariates. In a subgroup of patients with MELD-Na ≤ 20, HHT continued to be a significant predictor of one-year mortality (HR 3.30, 95% CI 1.47-7.40; P value 0.004).

CONCLUSIONS

Refractory HHT is a significant independent predictor of mortality and offers additional prognostic value.

Natural history and outcomes of patients with liver cirrhosis complicated by hepatic hydrothorax

BACKGROUND

Hepatic hydrothorax (HH) is an uncommon and difficult-to-manage complication of cirrhosis with limited treatment options.

AIM

To define the clinical outcomes of patients presenting with HH managed with current standards-of-care and to identify factors associated with mortality.

METHODS

Cirrhotic patients with HH presenting to 3 tertiary centres from 2010 to 2018 were retrospectively identified. HH was defined as pleural effusion in the absence of cardiopulmonary disease. The primary outcomes were overall and transplant-free survival at 12-mo after the index admission. Cox proportional hazards analysis was used to determine factors associated with the primary outcomes.

RESULTS

Overall, 84 patients were included (mean age, 58 years) with a mean model for end-stage liver disease score of 29. Management with diuretics alone achieved long-term resolution of HH in only 12% patients. At least one thoracocentesis was performed in 73.8% patients, transjugular intrahepatic portosystemic shunt insertion in 11.9% patients and 33% patients received liver transplantation within 12-mo of index admission. Overall patient survival and transplant-free survival at 12 mo were 68% and 41% respectively. At multivariable analysis, current smoking [hazard ratio (HR) = 8.65, 95% confidence interval (CI): 3.43-21.9, P < 0.001) and acute kidney injury (AKI) (HR = 2.91, 95%CI: 1.21-6.97, P = 0.017) were associated with a significantly increased risk of mortality.

CONCLUSION

Cirrhotic patients with HH are a challenging population with a poor 12-mo survival despite current treatments. Current smoking and episodes of AKI are potential modifiable factors affecting survival. HH is often refractory of diuretic therapy and transplant assessment should be considered in all cases.

Hepatic Hydrothorax: A Narrative Review

Hepatic hydrothorax (HH) represents a distinct clinical entity within the broader classification of pleural effusion that is associated with significant morbidity and mortality. The median survival of patients with cirrhosis who develop HH is 8-12 months. The diagnosis is typically made in the context of advanced liver disease and ascites, in the absence of underlying cardio-pulmonary pathology. A multi-disciplinary approach to management, involving respiratory physicians, hepatologists, and palliative care specialists is crucial to ensuring optimal patient-centered care. However, the majority of accepted therapeutic options are based on expert opinion rather than large, adequately powered randomized controlled trials. In this narrative review, we discuss the epidemiology, pathophysiology, clinical characteristics, and management of HH, highlighting the use of salt restriction and diuretic therapy, porto-systemic shunts, and liver transplantation. We include specific sections focusing on the role of pleural interventions and palliative care, respectively.

Nonmalignant Pleural Effusions

Although the potential causes of nonmalignant pleural effusions are many, the management of a few, including complicated pleural infections and refractory heart failure and hepatic hydrothoraces, can be challenging and requires the assistance of interventional pulmonologists. A pragmatic approach to complicated parapneumonic effusions or empyemas is the insertion of a small-bore chest tube (e.g., 14-16 Fr) through which fibrinolytics (e.g., urokinase and alteplase) and DNase are administered in combination. Therapeutic thoracenteses are usually reserved for small to moderate effusions that are expected to be completely aspirated at a single time, whereas video-assisted thoracic surgery should be considered after failure of intrapleural enzyme therapy. Refractory cardiac and liver-induced pleural effusions portend a poor prognosis. In cases of heart failure-related effusions, therapeutic thoracentesis is the first-line palliative therapy. However, if it is frequently needed, an indwelling pleural catheter (IPC) is recommended. In patients with hepatic hydrothorax, repeated therapeutic thoracenteses are commonly performed while a multidisciplinary decision on the most appropriate definitive management is taken. The percutaneous creation of a portosystemic shunt may be used as a bridge to liver transplantation or as a potential definitive therapy in nontransplant candidates. In general, an IPC should be avoided because of the high risk of complications, particularly infections, that may jeopardize candidacy for liver transplantation. Even so, in noncandidates for liver transplant or surgical correction of diaphragmatic defects, IPC is a therapeutic option as valid as serial thoracenteses.

Hepatic Hydrothorax and Congestive Heart Failure Induced Pleural Effusion

Pleural effusions (PEs) are frequently encountered in routine clinical practice, affecting more than 3000 people per million population every year. Heart and liver failures are two of the most common causes of transudative PE. Because these effusions have nonmalignant etiologies, they are commonly referred to as benign effusions despite of the poor prognosis they foretell in their refractory stages. Like malignant effusions, symptom management is important and plays a significant role in palliation when these effusions become refractory to medical therapy.

Pleural Interventions in the Management of Hepatic Hydrothorax

Hepatic hydrothorax can be present in 5% to 15% of patients with underlying cirrhosis and portal hypertension, often reflecting advanced liver disease. Its impact can be variable, because patients may have small pleural effusions and minimal pulmonary symptoms or massive pleural effusions and respiratory failure. Management of hepatic hydrothorax can be difficult because these patients often have a number of comorbidities and potential for complications. Minimal high-quality data are available for guidance specifically related to hepatic hydrothorax, potentially resulting in pulmonary or critical care physician struggling for best management options. We therefore provide a Case-based presentation with management options based on currently available data and opinion. We discuss the role of pleural interventions, including thoracentesis, tube thoracostomy, indwelling tunneled pleural catheter, pleurodesis, and surgical interventions. In general, we recommend that management be conducted within a multidisciplinary team including pulmonology, hepatology, and transplant surgery. Patients with refractory hepatic hydrothorax that are not transplant candidates should be managed with palliative intent; we suggest indwelling tunneled pleural catheter placement unless otherwise contraindicated. For patients with unclear or incomplete hepatology treatment plans or those unable to undergo more definitive procedures, we recommend serial thoracentesis. In patients who are transplant candidates, we often consider serial thoracentesis as a standard treatment, while also evaluating the role indwelling tunneled pleural catheter placement may play within the course of disease and transplant evaluation.

Refractory Spontaneous Bacterial Empyema in Cirrhotic Patient

Spontaneous bacterial empyema (SBEM), also called spontaneous bacterial pleuritis, is an infection of the pleural space that arises in the setting of cirrhosis and, by definition, the absence of pneumonia. It is likely underdiagnosed as its symptoms are nonspecific and it lacks standardized diagnostic and therapeutic recommendations. SBEM represents a distinct complication of hepatic hydrothorax with different pathogenesis, presentation, and treatment strategy from those of empyema secondary to pneumonia. Surprisingly, nearly 40% of episodes of spontaneous empyema are not associated with spontaneous bacterial peritonitis. Although SBEM is amenable to prompt antibiotic therapy, it has a high rate of mortality and morbidity. A high clinical suspicion is crucial for patient survival and timely initiation of appropriate antibiotics. Increased understanding, recognition, and standardization of treatment would help alleviate the relatively high burden of SBEM. In this case vignette, we provide a review of the relevant literature, and we describe a rare case of SBEM in a patient with a history of alcohol-associated liver cirrhosis and prior episode of spontaneous bacterial peritonitis (SBP). SBEM was diagnosed with thoracentesis and analysis of the aspirate, and he was treated with ceftriaxone with resolution of his presenting abdominal pain and leukocytosis.

Case Report: Indwelling Pleural Catheter Based Management of Refractory Hepatic Hydrothorax as a Bridge to Liver Transplantation

Introduction: Liver transplantation is the treatment of choice for decompensated liver disease, and by extension for hepatic hydrothorax. Persistent pleural effusions make it challenging for patients to maintain physiological fitness for transplantation. Indwelling pleural catheters (IPCs) provide controlled pleural fluid removal, including peri-operatively. The immune dysfunction of cirrhosis heightens susceptibility to bacterial infection and concerns exist regarding the sepsis potential from a tunnelled drain.

Method: Six patients were identified who underwent IPC insertion for hepatic hydrothorax before successful liver transplantation, between November 2016 and November 2017.

Results: All patients had recurrent transudative right sided pleural effusions. Mean age was 49 years (range 24–64) and mean United Kingdom Model for End-Stage Liver Disease score was 58. Four patients required correction of coagulopathy before insertion. There were no complications secondary to bleeding. Three patients were taught self-drainage at home of up to 1 litre (L) daily. A protocol was developed to ensure weekly review, pleural fluid culture and drainage of larger volumes in hospital. For every 2–3 L of pleural fluid drained, 100 mls of 20% Human Albumin Solution (HAS) was administered. On average an IPC was in situ for 58 days before surgery and drained 19 L of fluid in hospital. There was a small increase in average BMI (0.2) and serum albumin (2.1 g/L) at transplantation. There was one episode of stage one acute kidney injury secondary to high volume drainage. No further ascitic or pleural procedures were needed while an IPC was in situ. One thoracentesis was required after IPC removal. On average IPCs remained in situ for 7 days post transplantation and drained a further 2 L of fluid. Pleural fluid sampling was acquired on 92% of drainages in hospital. Of 44 fluid cultures, 2 cultured bacteria. Two patients had their IPCs and all other lines removed post transplantation due to suspected infection.

Conclusion: Our case series describes a novel protocol and successful use of IPCs in the management of refractory hepatic hydrothorax as a bridge to liver transplantation. The protocol includes albumin replacement during pleural drainage, regular clinical review and culture of pleural fluid, with the option of self-drainage at home.

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.

Optimal Management of Cirrhotic Ascites: A Review for Internal Medicine Physicians

Clinical history of liver cirrhosis is characterised by two phases: the asymptomatic phase, also termed 'compensated cirrhosis', and the phase of complications due to the development of portal hypertension and liver dysfunction, also termed 'decompensated cirrhosis', in which patients may develop ascites, the most frequent and clinically relevant complication of liver cirrhosis. Ascites can be classified into uncomplicated and complicated according to the development of refractoriness, spontaneous bacterial peritonitis (SBP) or the association with hepatorenal syndrome (HRS). In this narrative review, we will extensively discuss the optimal pharmacological and non-pharmacological management of cirrhotic ascites with the aim to offer an updated practical guide to Internal Medicine physicians. According to the amount of fluid in the abdominal cavity, uncomplicated ascites is graded from 1 to 3, and the cornerstone of its management consists of restriction of salt intake, diuretics and large-volume paracentesis (LVP); in recent years, long-term administration of human albumin has acquired a new interesting role. Refractory ascites is primarily managed with LVP and transjugular intrahepatic portosystemic shunt (TIPS) placement in selected patients. The occurrence of renal impairment, especially HRS, worsens the prognosis of patients with cirrhotic ascites and deserves a specific treatment. Also, the management of SBP faces the rising and alarming spread of antibiotic resistance. Hepatic hydrothorax may even complicate the course of the disease and its management is a challenge. Last but not least, liver transplantation (LT) is the ultimate and more effective measure to offer to patients with cirrhotic ascites, particularly when complications occur.

Pulmonary Complications in Patients with Liver Cirrhosis

Patients with advanced chronic liver diseases, particularly with decompensated liver cirrhosis, can develop specific pulmonary complications independently of any pre-existing lung disease. Especially when dyspnea occurs in combination with liver cirrhosis, patients should be evaluated for hepato-pulmonary syndrome (HPS), porto-pulmonary hypertension (PPHT), hepatic hydrothorax and spontaneous bacterial empyema, which represent the clinically most relevant pulmonary complications of liver cirrhosis. Importantly, the pathophysiology, clinical features, diagnosis and the corresponding therapeutic options differ between these entities, highlighting the role of specific diagnostics in patients with liver cirrhosis who present with dyspnea. Liver transplantation may offer a curative therapy, including selected cases of HPS and PPHT. In this review article, we summarize the pathogenesis, clinical features, diagnostic algorithms and treatment options of the 4 specific pulmonary complications in patients with liver cirrhosis.

Acute tension hydrothorax in chronic liver disease secondary to spontaneous diaphragmatic rupture

Pleural effusion in liver cirrhotics is more commonly transudative. A transudative pleural effusion secondary to ascites in decompensated cirrhosis is also known as hepatic hydrothorax and is usually due to fluid seepage through congenital pores in the diaphragm. The patient, a known case of decompensated chronic liver disease, presented with a massive, left-sided, rapidly accumulating and transudative pleural effusion secondary to spontaneous diaphragmatic rupture. Clinically, he developed sudden onset shortness of breath and became hypotensive. This is a rare entity, and was confirmed on CT thorax revealing a focal segment defect ~1.6 cm over the left hemidiaphragm. Ascites treatment consisting of diuretics with salt restriction and repeated thoracentesis with albumin replacement improved his symptoms and lead to a complete resolution of the effusion.

Pulmonary Complications of Portal Hypertension

The most common pulmonary complications of chronic liver disease are hepatic hydrothorax, hepatopulmonary syndrome, and portopulmonary hypertension. Hepatic hydrothorax is a transudative pleural effusion in a patient with cirrhosis and no evidence of underlying cardiopulmonary disease. Hepatic hydrothorax develops owing to the movement of ascitic fluid into the pleural space. Hepatopulmonary syndrome and portopulmonary hypertension are pathologically linked by the presence of portal hypertension; however, their pathophysiologic mechanisms are significantly different. Hepatopulmonary syndrome is characterized by low pulmonary vascular resistance secondary to intrapulmonary vascular dilatations and hypoxemia; portopulmonary hypertension features elevated pulmonary vascular resistance and constriction/obstruction within the pulmonary vasculature.

Hepatic Hydrothorax: An Updated Review on a Challenging Disease

Hepatic hydrothorax is a challenging complication of cirrhosis related to portal hypertension with an incidence of 5-11% and occurs most commonly in patients with decompensated disease. Diagnosis is made through thoracentesis after excluding other causes of transudative effusions. It presents with dyspnea on exertion and it is most commonly right sided. Pathophysiology is mainly related to the direct passage of fluid from the peritoneal cavity through diaphragmatic defects. In this updated literature review, we summarize the diagnosis, clinical presentation, epidemiology and pathophysiology of hepatic hydrothorax, then we discuss a common complication of hepatic hydrothorax, spontaneous bacterial pleuritis, and how to diagnose and treat this condition. Finally, we elaborate all treatment options including chest tube drainage, pleurodesis, surgical intervention, Transjugular Intrahepatic Portosystemic Shunt and the most recent evidence on indwelling pleural catheters, discussing the available data and concluding with management recommendations.

Hepatic hydrothorax: indwelling catheter-related Acinetobacter radioresistens infection

Hepatic hydrothorax, a rare and debilitating complication of cirrhosis, carries high morbidity and mortality. First-line treatment consists of dietary sodium restriction and diuretic therapy. Some patients, mainly those who are refractory to medical management, will require invasive pleural drainage. The authors report the case of a 76-year-old man in a late cirrhotic stage of alcoholic chronic liver disease, presenting with recurrent right-sided hepatic hydrothorax, portal hypertension, hepatosplenomegaly and thrombocytopaenia. After recurrent admissions and complications, the potential for adjusting diuretic therapy was limited. After unsuccessful talc pleurodesis, an indwelling tunnelled pleural catheter was placed with effective symptomatic control. One month later, the patient was readmitted with empyema due to Acinetobacter radioresistens Despite optimised medical and surgical treatment, the patient died 4 weeks later.

Hepatic Hydrothorax

Hepatic hydrothorax (HH) is a pleural effusion that develops in a patient with cirrhosis and portal hypertension in the absence of cardiopulmonary disease. Although the development of HH remains incompletely understood, the most acceptable explanation is that the pleural effusion is a result of a direct passage of ascitic fluid into the pleural cavity through a defect in the diaphragm due to the raised abdominal pressure and the negative pressure within the pleural space. Patients with HH can be asymptomatic or present with pulmonary symptoms such as shortness of breath, cough, hypoxemia, or respiratory failure associated with large pleural effusions. The diagnosis is established clinically by finding a serous transudate after exclusion of cardiopulmonary disease and is confirmed by radionuclide imaging demonstrating communication between the peritoneal and pleural spaces when necessary. Spontaneous bacterial empyema is serious complication of HH, which manifest by increased pleural fluid neutrophils or a positive bacterial culture and will require antibiotic therapy. The mainstay of therapy of HH is sodium restriction and administration of diuretics. When medical therapy fails, the only definitive treatment is liver transplantation. Therapeutic thoracentesis, indwelling tunneled pleural catheters, transjugular intrahepatic portosystemic shunt and thoracoscopic repair of diaphragmatic defects with pleural sclerosis can provide symptomatic relief, but the morbidity and mortality is high in these extremely ill patients.

Indwelling Tunneled Pleural Catheters for Refractory Hepatic Hydrothorax in Patients With Cirrhosis: A Multicenter Study

BACKGROUND

The outcome of indwelling pleural catheter (IPC) use in hepatic hydrothorax (HH) is unclear. This study aimed to review the safety and feasibility of the IPC in patients with refractory HH.

METHODS

A retrospective multicenter study of patients with HH from January 2010 to December 2016 was performed. Inclusion criteria were refractory HH treated with an IPC and an underlying diagnosis of cirrhosis. Records were reviewed for patient demographics, operative reports, and laboratory values. The Kaplan-Meier method was used to estimate catheter time to removal. The Cox proportional hazard model was used to evaluate for independent predictors of pleurodesis and death.

RESULTS

Seventy-nine patients were identified from eight institutions. Indication for IPC placement was palliation in 58 patients (73%) and bridge to transplant in 21 patients (27%). The median in situ dwell time of all catheters was 156 days (range, 16-1,978 days). Eight patients (10%) were found to have pleural space infection, five of whom also had catheter-site cellulitis. Two patients (2.5%) died secondary to catheter-related sepsis. Catheter removal secondary to spontaneous pleurodesis was achieved in 22 patients (28%). Median time from catheter insertion to pleurodesis was 55 days (range, 10-370 days). Older age was an independent predictor of mortality on multivariate analysis (hazard ratio, 1.05; P = .01).

CONCLUSIONS

We present, to our knowledge, the first multicenter study examining outcomes related to IPC use in HH. Ten percent infection risk and 2.5% mortality were identified. IPC placement may be a reasonable clinical option for patients with refractory HH, but it is associated with significant adverse events in this morbid population.

Efficacy and Safety of Indwelling Pleural Catheters in Management of Hepatic Hydrothorax: A Systematic Review of Literature

Hepatic hydrothorax (HH) is an infrequent but debilitating and therapeutically challenging complication of advanced liver cirrhosis. As evidence suggests against chest tube placement in HH, many clinicians are reluctant to place indwelling pleural catheters (IPCs) for non-malignant effusions like HH. We aim to study the efficacy and safety of IPCs as an alternative treatment option in our systematic review. A literature search was conducted using the electronic database engines MEDLINE, PubMed, EMBASE, Ovid, Scopus and Cochrane Library (Cochrane Central Register of Controlled trials and Cochrane Database of Systematic Reviews) from inception to April 2018 to identify published articles and reports addressing outcomes in patients treated for HH with IPCs. The risk of bias was rated for each study using the Cochrane criteria. The search strategy retrieved 370 papers, of which four case series were selected with a total of 111 patients. After the insertion of IPCs for HH, spontaneous pleurodesis was achieved in 16 (31.4%) out of 51 patients at a mean duration of 73-222 days. As far as secondary outcomes were concerned, the frequency of pneumothorax during or after the procedure was 0 (0%) out of 92 patients, pain at insertion site 12 (20%) out of 60 patients, catheter blockage two (2.9%) out of 68 patients, pleural fluid infection five (4.5%) out of 111 patients and catheter-site cellulitis one (3.1%) out of 32 patients. Re-accumulation of pleural fluid after catheter removal was mentioned in one study, wherein 12 (20%) out of 60 patients developed recurrence of pleural effusion. We conclude IPCs as an acceptable therapeutic option for the management of refractory pleural effusion in patients with HH. Although trans-jugular intrahepatic portosystemic shunt (TIPS) and liver transplantation are the gold standards for the management of pleural effusion in these patients, cost and availability are the major concerns with these treatment modalities. IPCs are a safe and efficacious alternative with a reasonable rate of spontaneous pleurodesis.

Indwelling Pleural Catheters in Hepatic Hydrothorax: A Single-Center Series of Outcomes and Complications

BACKGROUND

Treatment of hepatic hydrothorax (HH) generally involves sodium restriction, diuretics, and serial thoracentesis. In more advanced cases, transjugular intrahepatic portosystemic shunt and liver transplantation may be required. Previously, indwelling tube drainage has been avoided due to concerns regarding high complication rates and overall poor outcomes. Recently, indwelling pleural catheters (IPCs) have been proposed as a novel treatment option for HH.

METHODS

This study was a retrospective review of patients who had undergone IPC placement for HH over a 10-year period at a large liver transplant referral center. We tracked outcomes, including complication rates and liver transplantation, as well as biomarkers of nutritional status.

RESULTS

Sixty-two patients underwent IPC placement between 2007 and 2017, with 33 IPCs (53%) placed as a bridge to liver transplantation. Complications were recorded in 22 patients (36%); empyema was the most common, diagnosed in 10 patients (16.1%). Ten patients evaluated for liver transplantation underwent successful transplantation following IPC placement. There were statistically significant decreases in both BMI and serum albumin levels following IPC placement.

CONCLUSIONS

IPCs represent a potential treatment for refractory HH and should be used with caution in patients eligible for liver transplantation. Ideally, IPC use for these patients would be evaluated by a multidisciplinary team. IPC use may lead to small decreases in BMI and serum albumin levels in patients over time.

Respiratory Complications Before and After Liver Transplant

Respiratory complications before and after liver transplant are common, diverse, and potentially have a negative impact on patient outcomes. In this review, we discuss the most frequent respiratory conditions that patients may develop in the perioperative period. Their prevention and/or treatment may help to maximize the benefit these patients may derive from liver transplant. This review examines diagnostic and therapeutic approaches to these complications for hepatologists, surgeons, and critical care physicians.

The long-term outcomes of cirrhotic patients with pleural effusion

BACKGROUND/AIM

A pleural effusion is an abnormal collection of fluid in the pleural space and may cause related morbidity or mortality in cirrhotic patients. Currently, there are insufficient data to support the long-term prognosis for cirrhotic patients with pleural effusion. In this study, we investigated the short- and long-term effects of pleural effusion on mortality in cirrhotic patients and evaluated the benefit of liver transplantation in these patients.

PATIENTS AND METHODS

The National Health Insurance Database, derived from the Taiwan National Health Insurance Program, was used to identify 3,487 cirrhotic patients with pleural effusion requiring drainage between January 1, 2007 and December 31, 2010. The proportional hazards Cox regression model was used to control for possible confounding factors.

RESULTS

The 30-day, 90-day, 1-year, and 3-year mortalities were 20.1%, 40.2%, 59.1%, and 75.9%, respectively, in the cirrhotic patients with pleural effusion. After Cox proportional hazard regression analysis adjusted by patient gender, age, complications of cirrhosis and comorbid disorders, old age, esophageal variceal bleeding, hepatocellular carcinoma, hepatic encephalopathy, pneumonia, renal function impairment, and without liver transplantation conferred higher risks for 3-year mortality in the cirrhotic patients with pleura effusion. Liver transplantation is the most important factor to determine the 3-year mortalities (HR: 0.17, 95% CI 0.11- 0.26, P < 0.001). The 30-day, 30 to 90-day, 90-day to 1-year, and 1 to 3-year mortalities were 5.7%, 13.4%, 20.4%, and 21.7% respectively, in the liver transplantation group, and 20.5%, 41.0%, 61.2%, and 77.5%, respectively, in the non-liver transplantation group.

CONCLUSION

In cirrhotic patients, the presence of pleural effusion predicts poor long-term outcomes. Liver transplantation could dramatically improve the survival and should be suggested as soon as possible.

Hepatic hydrothorax: An update and review of the literature

This review considers the modern concepts of pathogenesis, diagnostic methods, and treatment principles of hepatic hydrothorax (HH). HH is the excessive (> 500 mL) accumulation of transudate in the pleural cavity in patients with decompensated liver cirrhosis but without cardiopulmonary and pleural diseases. It causes respiratory failure which aggravates the clinical course of liver cirrhosis, and the emergence of spontaneous bacterial pleural empyema may be the cause of death. The information was collected from the PubMed database, the Google Scholar retrieval system, the Cochrane reviews, and the reference lists from relevant publications for 1994-2016 using the keywords: "liver cirrhosis", "portal hypertension", "hepatic hydrothorax", "pathogenesis", "diagnostics", and "treatment". To limit the scope of this review, only articles dealing with uncomplicated hydrothorax in patients with liver cirrhosis were included. The analysis of the data showed that despite the progress of modern hepatology, the presence of HH is associated with poor prognosis and high mortality. Most patients suffering from it are candidates for orthotopic liver transplantation. In routine clinical practice, stratification of the risk for an adverse outcome and the subsequent determination of individual therapeutic strategies may be the keys to the successful management of the patient's condition. The development of pathogenetic pharmacotherapy and optimization of minimally invasive treatment will improve the quality of life and increase the survival rate among patients with HH.

Indwelling Pleural Catheters for Nonmalignant Effusions: Evidence-Based Answers to Clinical Concerns

Pleural effusions occur in 1.5 million patients yearly and are a common cause of dyspnea. For nonmalignant effusions, initial treatment is directed at the underlying cause, but when effusions become refractory to medical therapy, palliative options are limited. Tunneled pleural catheters (TPCs) are commonly used for palliation of malignant effusions, but many clinicians are reluctant to recommend these devices for palliation of nonmalignant effusions, citing concerns of infection, renal failure, electrolyte disturbances and protein-loss malnutrition. Based on the published experience to date, TPCs relieve dyspnea and can result in spontaneous pleurodesis in patients with nonmalignant effusions. The infection rate compares favorably to that for malignant effusions with possible increased risk in patients with hepatic hydrothorax and posttransplant patients. Renal failure, electrolyte disturbance and protein-loss malnutrition have not been observed. TPCs are a reasonable option in select patients to palliate nonmalignant effusions refractory to maximal medical therapy.

Mortality Following Catheter Drainage Versus Thoracentesis in Cirrhotic Patients with Pleural Effusion

BACKGROUND

Pleural effusion is an abnormal collection of body fluids that may cause related morbidity or mortality in cirrhotic patients. There are insufficient data to determine the optimal method of drainage, for symptomatic relief in cirrhotic patients with pleural effusion.

AIMS

In this study, we compare the mortality outcomes of catheter drainage versus thoracentesis in cirrhotic patients.

METHODS

The National Health Insurance Database, derived from the Taiwan National Health Insurance Program, was used to identify cirrhotic patients with pleural effusion requiring drainage between January 1, 2007, and December 31, 2010. In all, 2556 cirrhotic patients with pleural effusion were selected for the study and divided into the two groups (n = 1278/group) after propensity score matching.

RESULTS

The mean age was 61.0 ± 14.3 years, and 68.9% (1761/2556) were men. The overall 30-day mortality was 21.0% (538/2556) and was higher in patients treated with catheter drainage than those treated with thoracentesis (23.5 vs. 18.6%, respectively, P < 0.001 by log-rank test). After Cox proportional hazard regression analysis adjusted by patient sex, age, and comorbid disorders, the risk of 30-day mortality was significantly higher in cirrhotic patients who accepted catheter drainage compared to thoracentesis (hazard ratio 1.30, 95% confidence interval 1.10-1.54, P = 0.003). Old age, hepatic encephalopathy, bleeding esophageal varices, hepatocellular carcinoma, ascites, and pneumonia were associated with higher risks for 30-day mortality.

CONCLUSION

In cirrhotic patients with pleural effusion requiring drainage, catheter drainage is associated with higher mortality compared to thoracentesis.

Hepatic hydrothorax: clinical review and update on consensus guidelines

Hepatic Hydrothorax (HH) is defined as a pleural effusion greater than 500 ml in association with cirrhosis and portal hypertension. It is an uncommon complication of cirrhosis, most frequently seen in association with decompensated liver disease. The development of HH remains incompletely understood and involves a complex pathophysiological process with the most acceptable explanation being the passage of the ascetic fluid through small diaphragmatic defects. Given the limited capacity of the pleural space, even the modest pleural effusion can result in significant respiratory symptoms. The diagnosis of HH should be suspected in any patient with established cirrhosis and portal hypertension presenting with unilateral pleural effusion especially on the right side. Diagnostic thoracentesis should be performed in all patients with suspected HH to confirm the diagnosis and rule out infection and alternative diagnoses. Spontaneous bacterial empyema and spontaneous bacterial pleuritis can complicate HH and increase morbidity and mortality. HH can be difficult to treat and in our review below we will list the therapeutic modalities awaiting the evaluation for the only definitive therapy, which is liver transplantation.

Pigtail Catheter: A Less Invasive Option for Pleural Drainage in Egyptian Patients with Recurrent Hepatic Hydrothorax

Background and Aims. Treatment of hepatic hydrothorax is a clinical challenge. Chest tube insertion for hepatic hydrothorax is associated with high complication rates. We assessed the use of pigtail catheter as a safe and practical method for treatment of recurrent hepatic hydrothorax as it had not been assessed before in a large series of patients. Methods. This study was conducted on 60 patients admitted to Tanta University Hospital, Egypt, suffering from recurrent hepatic hydrothorax. The site of pigtail catheter insertion was determined by ultrasound guidance under complete aseptic measures and proper local anesthesia. Insertion was done by pushing the trocar and catheter until reaching the pleural cavity and then the trocar was withdrawn gradually while inserting the catheter which was then connected to a collecting bag via a triple way valve. Results. The use of pigtail catheter was successful in pleural drainage in 48 (80%) patients with hepatic hydrothorax. Complications were few and included pain at the site of insertion in 12 (20%) patients, blockage of the catheter in only 2 (3.3%) patients, and rapid reaccumulation of fluid in 12 (20%) patients. Pleurodesis was performed on 38 patients with no recurrence of fluid within three months of observation. Conclusions. Pigtail catheter insertion is a practical method for treatment of recurrent hepatic hydrothorax with a low rate of complications. This trial is registered with ClinicalTrials.gov Identifier: NCT02119169.

Thoracoscopic Mesh Repair of Diaphragmatic Defects in Hepatic Hydrothorax: A 10-Year Experience

BACKGROUND

The objective was to analyze the outcomes of thoracoscopic mesh repair for hepatic hydrothorax (HH) at our institution during the past 10 years.

METHODS

A total of 63 patients with refractory HH who underwent thoracoscopic mesh onlay reinforcement to repair diaphragmatic defects from January 2005 to December 2014 were included in the study. Mesh covering alone was used in 47 patients and mesh with suturing was used in 16 patients. Patient demographics, Child-Pugh class, and model for end-stage liver disease (MELD) score were evaluated to predict morbidity and mortality.

RESULTS

Of the patients (mean age, 60.4 ± 15 years; 31 men and 32 women), 14.3% had concomitant underlying diseases of renal insufficiency, 34.9% had diabetes mellitus, and 4.8% had pneumonia. Diaphragmatic blebs were the most common diaphragmatic defects (29 of 63 [46%]). After a median 20.5 months of follow-up examinations, 4 patients experienced recurrence. The 1-month mortality rate was 9.5% (6 of 63 patients). On multivariable analysis, underlying impaired renal function (p = 0.039) and MELD scores (p = 0.048) were associated with increased 3-month mortality in 16 patients. Contrary to the rising Child-Pugh score (p = 0.058), rising MELD scores represented an increase in kidney or liver failure and mortality. The main causes of 3-month mortality were septic shock (n = 6), acute renal insufficiency (n = 4), gastrointestinal bleeding (n = 4), hepatic encephalopathy (n = 1), and ischemic bowel (n = 1).

CONCLUSIONS

Thoracoscopic mesh repair for refractory HH improves symptoms and lowers the recurrence rate.

Spontaneous bacterial empyema in a non cirrhotic end stage renal disease patient with immunosuppression

Spontaneous Bacterial Empyema (SBEM) denotes infection of the pleural fluid in the absence of pneumonia. Almost all cases of SBEM in literature are described in a background of ascites secondary to cirrhosis. Contiguous spread of the infected ascitic fluid through defects in the diaphragm is the most likely mechanism of SBEM. Most of these cases are transudative in nature and are managed with antibiotics. Literature on SBEM in the absence of cirrhosis or ascites is very limited so far. We describe a 59 year old female with ESRD status post renal transplant, on chronic immunosuppression for renal allograft rejection who was admitted with pleuritic chest pain that turned to be secondary to right sided pleural effusion. Further evaluation revealed Escherichia coli in both the blood and pleural fluid. There was no clinical or imaging evidence of pneumonia as well as cirrhosis or ascites. She was managed as a case of SBEM requiring drainage by chest tube. Management of SBEM in non-cirrhotic individuals usually requires drainage with chest tube as against patients with liver cirrhosis with hepatic hydro-thorax in whom chest tube drainage is contraindicated for risk of massive protein and electrolyte depletion and dehydration.

Transjugular intrahepatic portosystemic stent shunt for medically refractory hepatic hydrothorax: A systematic review and cumulative meta-analysis

AIM: To assess the effectiveness of transjugular intrahepatic portosystemic stent shunt (TIPSS) in refractory hepatic hydrothorax (RHH) in a systematic review and cumulative meta-analysis.

METHODS: A comprehensive literature search was conducted on MEDLINE, EMBASE, and PubMed covering the period from January 1970 to August 2014. Two authors independently selected and abstracted data from eligible studies. Data were summarized using a random-effects model. Heterogeneity was assessed using the I² test.

RESULTS: Six studies involving a total of 198 patients were included in the analysis. The mean (SD) age of patients was 56 (1.8) years. Most patients (56.9%) had Child-Turcott-Pugh class C disease. The mean duration of follow-up was 10 mo (range, 5.7-16 mo). Response to TIPSS was complete in 55.8% (95%CI: 44.7%-66.9%), partial in 17.6% (95%CI: 10.9%-24.2%), and absent in 21.2% (95%CI: 14.2%-28.3%). The mean change in hepatic venous pressure gradient post-TIPSS was 12.7 mmHg. The incidence of TIPSS-related encephalopathy was 11.7% (95%CI: 6.3%-17.2%), and the 45-d mortality was 17.7% (95%CI: 11.34%-24.13%).

CONCLUSION: TIPSS is associated with a clinically relevant response in RHH. TIPSS should be considered early in these patients, given its poor prognosis.
