Evaluation of Recurrent Right-Sided Pleural Effusion: Hepatic Hydrothorax vs. Silicone Breast Implant Rupture

We report a case of a 55-year-old woman who presented to our hospital emergency department with a recurrent right-sided pleural effusion. Her presenting symptom was shortness of breath which first began two years prior after she experienced a blunt thoracic injury. This injury resulted in the rupture of her right silicone breast implant. Since the traumatic rupture of her right breast implant, she developed asthma-like symptoms and allergies that were adequately controlled with bronchodilators, antihistamines, and glucocorticoids. Laboratory investigation was significant for elevated immunoglobulin E (IgE) levels and eosinophilia consistent with an allergic hypersensitivity reaction. She denied a history of smoking, asthma, or allergies preceding the trauma to her right breast implant. Our differential diagnosis also included the possibility of an inflammatory reaction to the silicone breast rupture as a possible etiology for the recurrent pleural effusion.

The patient underwent a right-sided diagnostic and therapeutic thoracentesis procedure on two separate occasions within a span of a month in an effort to improve her symptoms and arrive at a definitive diagnosis. Her worsening symptoms were believed to be triggered by the pleural effusion. Aspirated pleural fluid was sent to the laboratory for analysis. Both samples excluded infectious or malignant causes of the pleural effusion. Ultimately, the source of her pleural effusion was determined to be decompensated liver cirrhosis. The patient underwent a pleurodesis procedure in an effort to seal the pleural space. 

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.

Effectiveness and Safety of Pleurodesis for Hepatic Hydrothorax: A Systematic Review and Meta-Analysis

BACKGROUND

Hepatic hydrothorax (HH) is a serious complication of end-stage liver diseases, which is associated with poor survival. There is no consensus regarding the treatment of HH.

AIM

To evaluate the effectiveness and safety of pleurodesis for HH in a systematic review with meta-analysis.

METHODS

All relevant papers were searched on the EMBASE and PubMed databases. As for the data from the eligible case reports, the continuous data were expressed as the median (range) and the categorical data were expressed as the frequency (percentage). As for the data from the eligible case series, the rates of complete response and complications were pooled. The proportions with 95 % confidence intervals (CIs) were calculated by using random-effect model.

RESULTS

Twenty case reports including 26 patients and 13 case series including 180 patients were eligible. As for the case reports, the median age was 55 years (range 7-78) and 15 patients were male. The prevalence of ascites was 76 % (19/25). Seventeen (65.38 %) patients responded favorably to pleurodesis. As for the case series, the mean age was 51.5-63.0 years and 83 patients were male. The pooled prevalence of ascites was 90 % (95 % CI 81-97 %) in 7 studies including 71 patients. The complete response rate after pleurodesis was reported in all studies, and the pooled rate was 72 % (95 % CI 65-79 %). Complications related to pleurodesis were reported in 6 studies including 63 patients, and the pooled rate was 82 % (95 % CI 66-94 %).

CONCLUSION

Pleurodesis may be a promising treatment for HH, but carries a high rate of complications.

Evidence-based review of the management of hepatic hydrothorax

Hepatic hydrothorax (HH) is an example of a porous diaphragm syndrome. Portal hypertension results in the formation of ascitic fluid which moves across defects in the diaphragm and accumulates in the pleural space. Consequently, the treatment approach to HH consists of measures to reduce the formation of ascitic fluid, prevent the movement of ascitic fluid across the diaphragm, and drain or obliterate the pleural space. Approximately 21-26% of cases of HH are refractory to salt and fluid restriction and diuretics and warrant consideration of additional treatment measures. Ideally, liver transplantation is the best treatment option; however, most of the patients are not candidates and most of those who are eligible die while waiting for a transplant. Treatment measures other than liver transplantation may not only provide relief from dyspnea but also improve patient survival and serve as a bridge to liver transplantation.

Diaphragmatic repair of hepatic hydrothorax with VATS after abdominal insufflation with CO(2)

Hepatic hydrothorax is defined as the presence of a significant pleural effusion that develops in a patient with cirrhosis of the liver who does not have an underlying cardiac or pulmonary disease. There have been few published case reports dealing with hepatic hydrothorax treated surgically. Recently, we treated a patient with refractory hepatic hydrothorax by directly suturing the diaphragmatic defect during VATS. During surgery, the diaphragmatic defect was identified by using abdominal insufflation with CO(2) . The defect was sutured and the diaphragm was covered by polyglycolic acid felt and fibrin glue. After surgery, the patient's pleural effusion improved, his postoperative course was uneventful and he did not require a drainage tube at discharge.

Right diaphragmatic defect in hepatic hydrothorax exposed by contrast-enhanced ultrasonography after radiofrequency ablation

A 68-year-old male with liver cirrhosis and hepatocellular carcinoma treated by radiofrequency ablation was hospitalized for right hepatic hydrothorax and ascites. Perflubutane injected into the peritoneal cavity after an ultrasonography contrast agent revealed jet-like flow from the ascites to a pleural effusion, indicating a diaphragmatic defect. A hepatic hydrothorax was sutured under thoracoscopy and did not recur. An intraperitoneal injection of perflubutane enables a less-invasive diagnosis of a diaphragmatic defect.

Video-assisted thoracoscopic surgery (VATS) for the treatment of hepatic hydrothorax: report of twelve cases

BACKGROUND

Hepatic hydrothorax is defined as a significant pleural effusion in patients with liver cirrhosis and without underlying cardiopulmonary diseases. Treatment of hepatic hydrothorax remains a challenge at present.

METHODS

Herein we share our experiences in the treatment of 12 patients with hepatic hydrothorax by video-assisted thoracoscopic surgery (VATS). Repair of the diaphragmatic defects, or pleurodesis by focal pleurectomy, talc spray, mechanical abrasion, electro-cauterization or injection was administered intraoperatively, and tetracycline intrapleural injection was used postoperatively for patients with prolonged (>7 d) high-output (>300 ml/d) pleural effusion.

RESULTS

Out of the 12 patients, 8 (67%) had uneventful postoperative course and did not require tube for drainage more than 3 months after discharge. In 4 (33%) patients the pleural effusion still recurred after discharge due to end-stage cirrhosis with massive ascites.

CONCLUSION

We conclude that the repair of the diaphragmatic defect and pleurodesis through VATS could be an alternative of transjugular intrahepatic portal systemic shunt (TIPS) or a bridge to liver transplantation for patients with refractory hepatic hydrothorax. Pleurodesis with electrocauterization can be an alternative therapy if talc is unavailable.
