Study objectives: To analyze the outcome of talc slurry pleurodesis in patients with nonmalignant pleural effusions.
Design: Retrospective and partly prospective analysis of clinical outcome.
Setting: Hadassah University Hospital, Jerusalem, Israel.
Patients and participants: Between 1992 and 1997, we treated 16 patients with nonmalignant pleural effusion using talc slurry pleurodesis. The cause of effusion was congestive heart failure in 6 patients, liver cirrhosis in 4 patients, yellow nail syndrome in 1 patient, systemic lupus erythematosus in 1 patient, chylothorax in 1 patient, and undiagnosed in 3 patients.
Interventions: Nine patients were hospitalized, and seven patients received treatment in a day-care setting. Follow-up ranged from 2 months to 3 years.
Results: Complete success was observed in 12 cases (75%), partial success in 3 cases (19%), and pleurodesis was ineffectual in 1 case (6%). There were no significant complications after the procedure in any of our patients. A review of the English-language medical literature revealed an additional 110 reported cases of nonmalignant pleural effusion that were treated with chemical pleurodesis. Of these cases, talc was used in 65% with a success rate of nearly 100%.
Conclusions: Chemical pleurodesis, and specifically talc slurry, is an effective treatment for recurrent benign or undiagnosed pleural effusion. This procedure is safe and easily performed and, in selected cases, can be performed in an outpatient day-care setting.

Two to three grams of asbestos-free talc were suspended in 50 mL of saline solution (0.9%) with 20 mL of 1% lidocaine and injected via the intercostal drain into the pleural space. An additional 20 mL of saline solution was used to flush the drain. The drain was then clamped, and the patient was asked to change position every 10 to 15 min to allow adequate distribution of talc. After an additional 2 h, the chest radiograph was performed to exclude pneumothorax, and the intercostal drain was removed. Dipyrone (1 g po) or pethidine (50 to 75 mg IM) was administered at the discretion of the treating physician to control pain.
Day-care patients were sent home after 1 to 2 h of observation.
In 15 cases, talc slurry was used as the initial sclerosing agent. In one patient, tetracycline was tried, and failed, and was followed by successful talc administration.
Pleurodesis was considered to be completely successful if there was no reaccumulation of pleural fluid in the same hemithorax. Reaccumulation of fluid was determined using plain x-ray films only (posteroanterior, lateral). The procedure was considered to be partially successful if there was accumulation of some fluid but the patient did not require repeated thoracocentesis and was considered a failure if the rate of fluid accumulation was unchanged after pleurodesis.

In seven patients, pleurodesis was performed in a day-care setting, and nine patients were hospitalized. Day-care patients were kept in the hospital for 8 to 10 h but were not kept overnight.
A large-bore intercostal drain was used in eight patients, and a small Cook catheter was used in the remaining patients, including all ambulatory patients. Complete success rate of pleurodesis was greater with large-bore tubes (7 of 8 vs 5 of 8), although this difference was not significant. No difference between large and small tubes was noted when complete and partial successes were combined (7 of 8 vs 8 of 8).
Outcome
In 12 patients, pleurodesis was completely successful in
preventing fluid accumulation (Table 1)
. In three patients, the
procedure was partially successful, including one patient with YNS who
had a recurrence of effusion 2 months later. Thoracocentesis was
repeated, and in 6 months of follow-up, he had no further recurrence of
effusion. In the patient with chylothorax, pleurodesis was performed
three times but was ineffectual. In no case was pleurodesis followed by
worsening effusion in the contralateral chest cavity. There were no
cases of trapped lung in our patient population. Both clinical and
radiographic follow-up were obtained and ranged from 2 months to 3
years (mean, 8 months).
Complications
One patient experienced severe pleuritic pain lasting 3 days after
pleurodesis. Five patients died of their underlying diseases 2 to 8
months after therapy. There was no difference in success or
complication rate between hospitalized patients and outpatients.
| Discussion |
|---|
|
|
|---|
In our study, half the patients were treated using a small-bore Cook catheter. We observed no difference between small and large catheters in successful drainage of fluid, although more patients with large-bore tubes achieved complete success after pleurodesis. We do not think that this was related to the size of the tube. The small-bore tube is associated with less patient discomfort and is less traumatic.
A large number of our patients were treated in an ambulatory setting, with complete success achieved in five of eight cases and partial success in a further three cases. We believe that ambulatory management of these patients with benign effusion is an acceptable therapeutic option. It is obviously necessary to observe standard practice as regards talc pleurodesis, including the use of asbestos-free talc to avoid potential carcinogenesis, to ascertain that the lung has fully expanded before talc insertion, and to maintain sterile conditions before and during talc injection.
Reports from the English-language literature that described the use of chemical pleurodesis for nonmalignant pleural effusion and comparison of various agents are summarized in Table 2 .

Several authors have reported successful pleurodesis using various sclerosing agents,15 16 although recurrence in the other chest cavity may occur.17 In our series, we treated six cases of recurrent pleural effusion caused by CHF, all of which had a successful outcome. In no cases in our series was the procedure followed by worsening contralateral effusion.
Liver Cirrhosis
Pleural effusion occurs in approximately 6% of patients with
cirrhosis of the liver and clinical ascites.18
Pleural
fluid results from movement of ascitic fluid through diaphragmatic
defects or via diaphragmatic lymphatics because of increased
intra-abdominal pressure. Hypoalbuminemia with decreased intravascular
oncotic pressure predisposes to increased pleural interstitial liquid
pressure with subsequent entry into the pleural space. In 70% of
cases, effusion occurs on the right side, in 15%, on the left side,
and in 15%, the effusion is bilateral.18
Occasionally,
hepatic cirrhosis may produce a pleural effusion without associated
clinical ascites.19
We found reports of 24 cases of liver
cirrhosis with pleural effusion that were treated by pleurodesis. In 14
patients, talc was used, in 7, tetracycline, in 1, Atabrine
(quinacrine), and in 2, the name of the drug was not reported.
Vargas et al20 used talc in six patients. Five treatments were completely successful, and one patient needed repeat pleurodesis 4 months later. Falchuk et al21 reported two patients successfully treated with tetracycline. In contrast, Ikard and Sawyers22 reported two cases in which pleurodesis using tetracycline and quinacrine were unsuccessful. Runyon et al23 reported a patient in whom pleurodesis was unsuccessful and was followed by severe complications (hypotension, oliguria). They concluded that hepatic hydrothorax with congenital diaphragmatic defects is a contraindication to chest tube insertion. Mouroux et al24 attained complete resolution of pleural effusion using surgical video thoracoscopy with thoracoscopic closure of diaphragmatic defects and talc pleurodesis in six of eight cases.
Our study includes four patients with resistant pleural effusion because of liver cirrhosis. In all cases, pleurodesis was successful (three complete and one partial).
SLE
Pleural effusion is common in SLE. The fluid is usually exudative,
containing a high concentration of immunoglobulins and a low
concentration of complement. Classically, the effusion responds to
steroid therapy. Six cases of refractory pleural effusion secondary to
SLE treated with pleurodesis are described in the English-language
literature. Two reported attempts at pleurodesis using tetracycline
were unsuccessful.25
26
In these cases, subsequent
treatment with talc poudrage was effective, and in one,25
a second dose of tetracycline was instilled. In contrast, Gilleece et
al27
reported successful pleurodesis using tetracycline.
Our study includes one case of pleural effusion secondary to SLE that
was treated successfully with talc sclerotherapy.
Chylothorax
Our study included one patient with posttraumatic chylothorax in
whom two attempts at talc pleurodesis were unsuccessful.
A nonmalignant chylothorax may result from thoracic surgery, trauma, or movement of chylous ascites to the pleural space. Twenty-six cases of nonmalignant chylothorax treated with pleurodesis were found in our literature survey. Vargas et al20 successfully treated five patients by using talc for this purpose. Gingell28 reported the same results in 3 patients, Adler and Levinsky29 in 1, Weissberg and Kaufman30 and Weissberg31 in 7, and Fairfax et al32 in 3. Robinson33 and Lieberman and Agliozzo34 described two patients in whom effusion was completely controlled by intrapleural insufflation of nitrogen mustard. Strausser and Flye35 obtained positive results in treating chylothorax in a case of lymphangiomatosis.
Le Coultre et al36 described 24 cases of postoperative chylothorax in children of whom 4 were successfully treated by pleurodesis. No details regarding method of pleurodesis are provided.
YNS
YNS is rare disorder that presents with lymphedema and pleural
effusion with or without yellow nails. The pleural fluid is usually
exudative. The lymphedema and pleural effusion are chronic and
persistent, and spontaneous recovery has not been
reported.18
Chemical pleurodesis has been successful in
controlling effusion. There are 3 reports of effective talc
pleurodesis,8
37
3 reports of successful tetracycline
pleurodesis,38
39
and 1 with quinacrine.40
In
contrast, others reported failure of pleurodesis using tetracycline,
cyclophosphamide, and Atabrine for this purpose.26
41
Our
study included one patient with YNS in whom talc pleurodesis was
partially successful.
Nephrotic Syndrome
The mechanism for pleural fluid accumulation in nephrotic syndrome
is decreased oncotic pressure in the pleural microvascular circulation
due to hypoalbuminemia. Increased hydrostatic pressure from salt and
water overload may be contributory.18
Pulmonary
thromboembolism is a common complication in nephrotic patients. The
presence of hemorrhagic pleural fluid would suggest thromboembolic
disease. Occasionally, large unilateral or bilateral effusions occur.
Jenkins and Shelp42
reported a case of recurrent pleural
transudate in a patient with nephrotic syndrome in whom intrapleural
insufflation of tetracycline was successful in preventing recurrence.
Peritoneal Dialysis
Although peritoneal dialysis frequently is associated with small
bilateral effusion, massive unilateral effusion (usually right-sided)
is seen occasionally.43
Five cases of treatment with
pleurodesis have been described in the literature. Tetracycline was
used in 2 patients,44
talc in 2
patients,36
45
and autologous blood instillation in 1
case.46
Successful pleurodesis was achieved in all cases.
Other Causes
There are other reports describing the treatment of six patients
with empyema with talc pleurodesis,30
37
five patients
with AIDS,15
one patient with Dresslers
syndrome,47
two cases of recurrent effusion after
radiotherapy,8
47
three cases of asbestos
injury,47
and one of macroglobulinemia.8
All
patients were treated successfully with talc.
In conclusion, refractory or recurrent nonmalignant pleural effusion can be successfully treated by pleurodesis. In our series and the reported literature, the use of talc slurry is convenient and is associated with excellent outcome and minimal complications. In selected patients, this procedure can be performed in an ambulatory setting.
