Hepatic hydrothorax.

Hepatic hydrothorax (HH) is an uncommon manifestation of cirrhosis with ascites. Pleural effusions form when ascitic fluid moves through diaphragmatic defects that have been opened by increased peritoneal pressure. The diagnosis is established clinically by finding a serous transudate and is confirmed by radionuclide imaging demonstrating communication between the peritoneal and pleural spaces. In end-stage liver disease, the management of hepatic hydrothorax is problematic and often does not respond to medical therapy. Therapeutic options for a refractory hepatic hydrothorax include therapeutic thoracentesis, talc slurry through a chest tube, peritoneovenous and pleurovenous shunting, thoracoscopic talc poudrage, transjugular intrahepatic portosystemic shunt (TIPS), thoracosopic diaphragmatic defect repair followed by talc poudrage, and lastly, liver transplant. TIPS can be used as a bridge for transplantation but is often complicated by encephalopathy. Video assisted thoracic surgery (VATS) with patching the defect and talc poudrage may provide symptomatic relief; however, the morbidity and mortality in these extremely ill patients is high. The only definitive treatment for refractory hepatic hydrothorax associated with end-stage cirrhosis is liver transplantation.

Thoracoscopy talc poudrage : a 15-year experience.

OBJECTIVES: To review our experience with thoracoscopy and talc poudrage during the previous 15 years with regards to efficacy, side effects, morbidity, and mortality. METHODS: Six hundred fourteen consecutive patients (58.6% female; mean age, 54.5 years) underwent thoracoscopy with talc poudrage from August 1983 to May 1999. Of these, 457 patients had malignant pleural effusions, 108 patients had benign pleural effusions, and 49 patients had spontaneous pneumothorax. RESULTS: Sixty-four patients were excluded from evaluation for efficacy: 30 patients (4.9%) because the lung did not expand at the time of the procedure and 34 patients (5.5%) because they died within 30 days of the thoracoscopy. All exclusions were in the malignant group. The overall success rate of the 393 patients with malignant pleural effusions was 93.4%, while the overall success for the 108 patients with benign effusions was 97%, although 7 patients (7%) with benign effusions required a second thoracoscopy. The success rate with pneumothorax was 100%. Major morbidity included empyema in 4%, reexpansion pulmonary edema in 2.2%, and respiratory failure 1.3%. CONCLUSION: Thoracoscopy with talc poudrage is effective in producing a pleurodesis in malignant and benign pleural effusion and in spontaneous pneumothorax. However, it should be noted that the insufflation of talc has a systemic distribution associated with a low rate of morbidity and perhaps does induce ARDS, which is sometimes fatal in a small percentage of patients. Because of these side effects, the search for a better agent should be continued.

Thoracoscopy and talc poudrage in the management of hepatic hydrothorax.

STUDY OBJECTIVE: To determine indications, limitations, morbidity and mortality of surgical thoracoscopy for management of hepatic hydrothorax, a rare, but often recurrent, complication in cirrhotic patients. PATIENTS AND METHODS: From May 1985 through May 1999, 10 men and 8 women, with a mean age of 57.6 years (range, 26 to 76 years), underwent 21 therapeutic thoracoscopies to achieve pleurodesis by application of talc. RESULTS: The procedure was effective in 10 of 21 procedures. There were four recurrences (19. 1%) that were retreated, with only one being successful. In this specific group, we detected high morbidity (57.1%) and mortality (38.9%) during the follow-up period of 3 months. Diaphragmatic defects were localized and closed five times (23.8%). Hospital stay was approximately 15 days (range, 5 to 41 days). CONCLUSION: The procedure appears to be indicated for these fragile patients, especially when medical therapy fails. Immediate efficacy was 47.6%, increasing to 60% with videothoracoscopy and suture of the diaphragmatic defect. However, morbidity and mortality were high.
