Thoracoscopic talc poudrage in malignant pleural effusions: effective pleurodesis despite low pleural pH.

STUDY OBJECTIVE: To determine the effectiveness of pleurodesis by thoracoscopic talc poudrage (TTP) in patients with low pH malignant pleural effusions. DESIGN: Review of prospectively collected data on all thoracoscopic procedures performed from 1982 to 1996. PATIENTS AND SETTING: Twenty-five members in a prepaid, closed-panel health maintenance organization, whose malignant pleural effusion pH was < or = 7.30. INTERVENTIONS: Pleural fluid pH was measured prior to diagnostic and therapeutic, single puncture, rigid thoracoscopy, under local anesthesia, in an operating room. MEASUREMENTS AND RESULTS: Success of pleurodesis was determined with serial radiographs at 10 days, 30 days, and frequent intervals until death or up to 1 year following the procedure. Failure was indicated by evidence of recurrent fluid or persistence of a space between the visceral and parietal pleura. Morbidity of the procedure, days of chest tube drainage, and days of hospitalization were recorded concurrently during hospitalization and outpatient follow-up. Fifty of the 76 patients found to have a pleural pH measurement had a pleural pH >7.30, averaging 7.37 (7.31 to 7.55). The other 26 patients (34%) with pH < or = 7.30 (low pH) are the subjects of this study, of whom 25 were evaluable. Pleurodesis was successful in 22 of 25 (88%), although 4 died prior to 30 days. The three failures all had trapped lung. Chest tube drainage averaged 3.2+/-1.3 days, which approximated the time of hospitalization (3.3+/-1.1 days). There were no thoracoscopy-related deaths; significant morbidity occurred only in one patient with trapped lung, who had prolonged chest tube drainage before and after TTP, and eventually developed empyema. CONCLUSIONS: TTP is an effective pleurodesis technique in malignant pleural effusions, even when the pleural pH is low. The short hospital stay and high success rate make this approach a good choice in palliating symptomatic malignant pleural effusions.

Evaluation of the effect of the concentration of plasticizer di(2-ethylhexyl) phthalate on the quantity of residual monomer vinyl chloride in PVC chest drainage tubes.

The effect of amount of plasticizer di(2-ethylhexyl) phthalate (DEHP) amount on the amount of residual monomer vinyl chloride (VC) was determined in samples of plasticised polyvinyl chloride (PVC) with different concentration of plasticiser (22.32-33.05%), before and after sterilisation by a titrimetric method. The titrimetric method was used to determine the VC concentration in a KMnO4 solution where the samples were kept immersed under the same conditions for 2 h. The influence of PVC film extracts with different amounts of DEHP on mouse fibroblast cells L-929 in a culture medium was evaluated by using quantitative tests: the amount of cells (protein determination), viability (MTT test) and proliferation (incorporation of bromodeoxyuridine (BrDU). The amount of vinyl chloride before and after heat sterilisation at 120 degrees C for 30 min was found to be almost the same for all samples and without any dependence on the concentration of DEHP. The extracts of the PVC films which were tested have no toxic effect on cells in a culture medium.

What keeps postpulmonary resection patients in hospital?

BACKGROUND: Prolonged air leak (longer than three days) was hypothesized to be the primary cause of extended hospital stays following pulmonary resection. Its effect on length of stay (LOS) was compared with that of suboptimal pain control, nausea and vomiting, and other causes. Predictors of prolonged LOS and of prolonged air leaks were investigated. DESIGN: Retrospective review of 91 patients. Primary reasons for prolonged hospitalization were determined. Patient characteristics (demographic information, pulmonary function test results, body habitus measurements, smoking history), operative factors (procedure performed, duration of operation, complications) and postoperative factors (time of chest tube removal) were considered. Student's t test and chi2 analysis were used to compare continuous and ratio data, respectively, and linear regression analysis was used to define the equation relating two variables. RESULTS: The mean postoperative LOS was 6.4 days. Only prolonged air leak was predictive of increased LOS (9.4 days versus 5.4 days, P<0.001). Forced expiratory volume in 1 s less than 1.5 L/min, carbon monoxide diffusing capacity less than 80% predicted and the detection of a pneumothorax were all predictive of prolonged air leak. A strong correlation between the time of chest tube removal and LOS was found (r=0.937, P<0.001). Linear regression analysis showed postoperative LOS and duration of thoracostomy tube insertion to be related by the equation y = 0.88x + 2.49 days. CONCLUSION: These results suggest that increased LOS following pulmonary resection is due primarily to prolonged air leaks. Furthermore, patients who have their chest tubes removed sooner are discharged sooner.

Decreased platelet number and function and increased fibrinolysis contribute to postoperative bleeding in cardiopulmonary bypass patients.

We simultaneously evaluated platelet and fibrinolytic parameters to assess their individual and combined contributions to postoperative blood loss in cardiopulmonary (CP) bypass patients. Platelet count, platelet aggregability, hematocrit, plasminogen (PLG) concentration, alpha 2-antiplasmin (AP) concentration, free protease activity (fPA), and antithrombin-III (AT-III) were measured in nine patients undergoing surgery using cardiopulmonary bypass. Chest tube drainage was used as the measure of postoperative blood loss. Hematocrit, platelet count, PLG, AP, and AT-III all decreased during CP bypass, with PLG and AT-III decreasing much more than dilution. During CP bypass, platelet aggregability to ADP did not change significantly from pre-bypass, but aggregability to arachidonic acid (AA) decreased significantly. Following protamine administration there was a large increase (83%) in fPA, the platelet count showed a further drop (from 61% to 50% of pre-bypass levels), and platelet aggregability decreased significantly (from 95% to 34% of pre-bypass levels for ADP, and from 55% to 11.9% for AA). Chest tube drainage during the first four postoperative hours correlated positively (p less than 0.05) with the combination of increase in free protease activity and decrease in platelet count. The total chest tube drainage correlated significantly with the combination of decrease in platelet count and the decrease in platelet aggregability. These combinations of changes correlated significantly with postoperative blood loss whereas the individual changes did not.(ABSTRACT TRUNCATED AT 250 WORDS)

[The use of tissue glue and its effect on hospital cost in patients undergoing pulmonary surgery].

Prolonged air leak following pulmonary resections is an important cause of morbidity and increased hospital costs. We compared 19 homologous/autologous tissue glue (fibrin glue) applied patients (FG group), 12 beriplast-P applied patients (beriplast group) and 27 control patients with respect to prolonged air leak, chest tube removal time and hospital costs. The mean ages for FG group (19 patients), beriplast group (12 patients) and control group (27 patients) were 48.5 +/- 14, 50.5 +/- 6.8 and 55 +/- 12.9 respectively. The groups were comparable with respect to age (p= 0.210), sex (p= 0.287) and the surgical procedure performed (p= 0.289). The incidence of prolonged air leak in FG group, beriplast group and the control group was 48%, 50% and 63%, respectively (p= 0.533). The mean chest tube removal time in FG group, beriplast group and the control group was 10.7 +/- 8.7, 9 +/- 4.1 and 8 +/- 3.1 days, respectively (p= 0.282). Mean hospital costs in FG group, beriplast group and the control group were 4633 +/- 3272 YTL, 4611 +/- 1583 YTL and 4015 +/- 911 YTL, respectively (p= 0.547). Fibrin glue had no effect on the incidence of prolonged air leak, chest tube removal time and hospital costs.

Effect of fibrin glue on air leak and length of hospital stay after pulmonary lobectomy.

AIM: Air leaks are a common cause of morbidity and prolonged hospital stay after pulmonary lobectomy. We reviewed our experience with intraoperative fibrin glue to determine if it reduced air leak and improved patient outcomes. METHODS: Records of patients undergoing pulmonary lobectomy for benign or malignant disease over a 4-year period (1998-2001) were reviewed. Data was collected on age, sex, pulmonary function, pulmonary pathology, use of fibrin glue, duration of chest tube drainage, length of hospital stay, and postoperative complications. RESULTS: Three hundred and sixty patients underwent lobectomy. Fibrin glue was used intraoperatively to seal air leaks in 102 of the 360 patients (study group: 102;control group: 258). Fibrin glue was used at the discretion of the surgeon, with some surgeons using it routinely. The groups did not differ in age (p=0.29), sex (p=0.42), FEV1 (p=0.57), or pathology (p=0.08). There were no differences in outcomes such as operative mortality (study: 2 of 102, control 6 of 258, p=0.85), empyema (study: 0 of 102, control: 3 of 258, p=0.55), prolonged (>7 days) air leaks (study: 10 of 20; control: 20 of 258, p=0.71), or length of hospital stay (study: 6.3+/-2.5 days, control:7.7+/-7.2 days, p=0.83). The use of fibrin glue was associated with a reduction in the duration of chest tube intubation (study: 4.1+/-3.2 days, control: 5.5+/-3.8 days, p=0.001). CONCLUSION: Patients treated intraoperatively with fibrin glue had a significantly shorter duration of chest tube intubation after pulmonary lobectomy than those treated conventionally. However, the use of fibrin glue did not significantly influence more clinically relevant outcomes such as length of hospital stay and incidence of prolonged (>7 days) air leaks.

Management of penetrating lung injuries in civilian practice.

Recent reports of military thoracic injuries have advocated early thoracotomy and aggressive management of pulmonary injuries with resection as opposed to the more conservative and traditional treatment with chest tube thoracostomy. A retrospective study was therefore performed to determine the incidence of thoracotomy and lung resection in civilian injuries and to evaluate the effectiveness of treatment of these injuries. Between 1973 and 1985, in a series of 1,168 patients, there were 384 gunshot wounds and 784 stab wounds to the thorax. Two hundred eighty-three patients with a gunshot wound (74%) and 602 with a stab wound (77%) were treated with chest tubes alone. Sixty-eight patients (6% of the total) required operative repair of pulmonary hilar or parenchymal injury. Pulmonary resection was necessary in only 18 patients (nine with a gunshot wound and nine with a stab wound), and 10 patients had repair of hilar injuries (nine with a gunshot wound and one with a stab wound). Of patients requiring pulmonary resection, nine required wedge or segmental resection, six required lobectomy, and three patients required pneumonectomy. Mortality for all thoracic injuries was 2.3%: for those treated with chest tube alone, 0.7%; for pulmonary hilar injuries, 30%; for pulmonary parenchymal injuries, 8.6%; and for injuries necessitating lung resection, 28%. Most civilian lung injuries can be treated by tube thoracostomy alone. Although relatively few patients with primary pulmonary injury require thoracotomy, those that do are at significant risk and may require lung resection to control bleeding or hemoptysis or to remove destroyed or devitalized lung tissue.

Fast-tracking pulmonary resections.

OBJECTIVE: We streamlined our care after pulmonary resection for quality and cost-effectiveness. METHODS: A single surgeon performed 500 consecutive pulmonary resections through a thoracotomy over a 2(3/4)-year period in a university setting. Patients were extubated in the operating room and sent directly to their hospital room. Chest tubes were placed to water seal and removed on postoperative day 2 if there was no air leak and drainage was less then 400 mL/d. Epidural catheters were used and removed by postoperative day 2. The plan for each day and discharge on postoperative day 3 or 4 was reviewed with the patients and families daily during rounds. The patient went home the day the last chest tube was removed. Persistent air leaks were treated with Heimlich valves. RESULTS: There were 500 patients (338 men), with a median age of 58 years (range, 3-87 years). Of these patients, 293 had pre-existing conditions. Seventy-three (15%) patients had been denied operations by at least one other surgeon. Four hundred nineteen (84%) patients had successful placement of a functioning preoperative epidural catheter. Pneumonectomy was performed in 32 (6%) patients, segmentectomy was performed in 16 (3%) patients, and lobectomy, sleeve lobectomy, and/or bilobectomy was performed in 194 (39%) patients. Nonanatomic resections were performed for metastasectomy. This included a single wedge resection in 161 (32%) patients and multiple wedge resections in 97 (19%) patients. A total of 482 (96%) patients were extubated in the operating room, and 380 (76%) patients were sent to their hospital room. The remaining 120 patients went to the intensive care unit for a median of 1 day (range, 1-41 days). Complications occurred in 107 (21%) patients, and operative mortality was 2.0%. Median day of discharge was postoperative day 4 (range, 2-119 days). A total of 327 (65%) patients left the hospital on postoperative day 4 or sooner. By survey, 97% of patients had excellent or good satisfaction with their care at hospital discharge, and 91% were extremely happy or satisfied at the 2-week follow-up contact. CONCLUSIONS: Most patients who undergo elective pulmonary resection can be extubated immediately after the operation, go directly to their room and avoid the intensive care unit, be discharged on postoperative day 3 or 4, and have minimal morbidity and mortality with high satisfaction both at discharge and at the 2-week follow-up contact. Techniques that seem to accomplish this include the following: the use of a water seal, removal of epidural catheters on postoperative day 2, early chest tube management, treatment of persistent air leaks with Heimlich valves, and daily reinforcement of the planned events for each day, as well as on the date of discharge with the patients and their families.

[Current value of intrapleural fibrinolysis in the treatment of exudative fibrinous pleural effusions in pleural empyema and hemothorax].

Intrapleural administration of fibrinolytic agents has been in use for fifty years; it has, however, been of clinical importance only for the last twenty years. Parallel to clinical reports procoagulant and fibrinolytic activities in pleural effusions are studied. Most types of pleural injury are characterised by fibrin deposition in the pleural space promoted by concurrent local abnormalities of pathways of fibrin formation and its clearance. Many of the studies of intrapleural fibrinolytics are uncontrolled and retrospective or small and are therefore of limited statistical value. Only five of the studies which are presented in the table are controlled and comparative studies. Intrapleural fibrinolytic therapy was used in exudative fibrinous multi-loculated pleural effusions, pleural empyemas and haemothorax. The global success rate of the studies cited were between 44% and 100%, in most cases more than 80%. The great differences in success rates are due to variations in the pleural diseases and stages of the clinical course, different success criteria, different dosages of fibrinolytic agents, different durations of clamped chest tube drainage and different starting points of therapy during the hospital course. The number of patients enrolled in each study ranged from 8 to 98, the number of children ranged from 2 to 9. Intrapleural fibrinolytic treatment is associated with rare adverse effects. There is no significant systemic fibrinolytic activity of intrapleural fibrinolysis. Intrapleural administration of streptokinase has been reported to lead to antibody formation. Hence, intrapleural fibrinolytic therapy is a useful adjunct in the management of exudative fibrinous multi-loculated pleural effusions, pleural empyemas and haemothorax. There is an increased volume of pleural fluid drainage during the treatment phase, and intrapleural fibrinolysis may reduce the need for more invasive surgical procedures. On the basis of the data of literature we recommend to use a single daily dose of 250,000 U streptokinase or 100,000 U urokinase in 50-100 ml normal saline instilled into a chest tube and to maintain dwell times of 2 to 4 hours. Therapy can be continued up to 2 weeks. The pleural space can be drained by large bore chest tubes or small drainage catheters, both radiologically guided, without preference for one method.

Early experience with activated recombinant factor VII for intractable hemorrhage after cardiovascular surgery.

BACKGROUND: Intractable hemorrhage after complex cardiovascular operations is a serious and potentially lethal complication. We report our experience with the use of activated recombinant factor VIIa (rFVIIa) as rescue therapy for patients with refractory postoperative hemorrhage. METHODS: From April 2002 through December 2003, 9 patients received rFVIIa for intractable hemorrhage after cardiovascular surgery. Patients underwent aortic surgery (2), coronary artery bypass graft surgery (4), double valve operations (2), and mitral valve replacement (1). Four of these procedures were reoperations. Intraoperative aprotinin was used in all patients. All patients underwent standard heparinization (300 IU/kg) before cardiopulmonary bypass and reversal with protamine. RESULTS: Five patients underwent reexploration for mediastinal hemorrhage before treatment; 2 were reexplored twice. The average transfusion requirement before rFVIIa administration was 9 U of blood, 7 U of plasma, 22 U of platelets, and 19 U of cryoprecipitate. rFVIIa was administered as an intravenous bolus at 68 to 120 mug/kg. Mean time of administration from the first operation was 10.9 +/- 7.2 hours. At the time of activated rFVIIa administration, chest tube drainage averaged 640 mL/h. In all patients, chest tube drainage was dramatically reduced to less than 100 mL/h within 5 hours after drug delivery. None of the patients required reexploration after treatment. There were no postoperative neurologic or cardiovascular complications. CONCLUSIONS: When used as rescue therapy for intractable hemorrhage after cardiovascular surgery, rFVIIa may be effective in promoting hemostasis, preventing reexploration, and reducing transfusion requirements.

Severe pneumothorax after intercostal nerve blockade. A case report.

BACKGROUND: Intercostal nerve blockade is recognized as an efficient and safe regional anesthetic technique. Although an appropriate technique was applied, we report a severe pneumothorax associated with this type of regional anesthesia. METHODS: A 57-year-old female patient underwent block of intercostal nerves 3 to 8 for interstitial radiotherapy of the left breast in the sitting position. Calcified residual foci in the right upper lobe from a previous primary infection of tuberculosis were diagnosed by preoperative x-ray. After completion of the blocks in the midline of the axilla, the patient complained of pain between the scapulas, developed severe dyspnea and panic, and felt as if her life was in jeopardy. A severe pneumothorax was diagnosed and a chest tube was placed. After the application of the chest tube, the patient recovered quickly. CONCLUSION: Extra caution should be used in applying this procedure to patients with underlying chronic lung disease, especially on the opposite side. Our case demonstrates that in all patients undergoing intercostal nerve blockade preference should be given to the approach at the dorsal angulation of the rib in the lateral or prone position due to its lower risk of pneumothorax.

[Cerebrospinal fluid fistula following an operation of mediastinal schwannoma: a case report].

A 33-year-old man was operated for the mediastinal schwannoma. During the operation, the 9 th intercostal nerve was avulsed and revealed liquorrhea. Lyodura and fibrin glue was applied for sealing the site of dural defect. But post-operative course was not successful. So, we used the external cerebrospinal fluid drainage system. After this procedure, thoracic fluid from the chest tube was reduced and we could remove the chest tube in the 20th post operative day. This case indicates that in case of thoracotomy, it is difficult to expect easy closure of cerebrospinal fluid fistula under conservative therapy. Therefore it was considered that specific repair during the operation and spinal drainage in the post-operative early phase should be performed.

Surgical sealant for preventing air leaks after pulmonary resections in patients with lung cancer.

BACKGROUND: Postoperative air leak is a frequent complication after pulmonary resection for lung cancer. It may cause serious complications, such as empyema, or prolong the need for chest tube and hospitalisation. Surgical sealants of different types have been developed to prevent or to reduce postoperative air leaks. A systematic review was therefore undertaken to evaluate the evidence on their effectiveness. OBJECTIVES: To evaluate the effectiveness of surgical sealants in preventing or in reducing postoperative air leaks after pulmonary resection for lung cancer. SEARCH STRATEGY: Electronic databases and, bibliographies were searched and, hand searching of conference proceedings was conducted to identify published and unpublished trials. SELECTION CRITERIA: Randomised controlled clinical trials were included in which standard closure techniques plus a sealant were compared with the same intervention with no use of any sealant in patients undergoing elective pulmonary resection provided that a large proportion of the patients studied had undergone pulmonary resection for lung cancer. DATA COLLECTION AND ANALYSIS: Two reviewers independently selected the trials to be included in the review, assessed methodological quality of each trial and extracted data using a standardised form. Because of several limitations, narrative synthesis was used at this stage. MAIN RESULTS: Two hundred and thirty-two patients from 4 trials were included. In two trials no differences were found between treatment and control patients in terms of reduction of duration of air leaks, chest tube drainage, hospitalisation or complications attributable to prolonged intercostal drainage. In the other two trials, postoperative air leaks were significantly reduced in the treatment groups, but there were no differences in hospital stay, complications, fever, intraoperative and postoperative intubation times, chest tube drainage or cost. REVIEWER'S CONCLUSIONS: Systematic use of surgical sealants in clinical practice cannot be recommended at the moment. More randomised controlled clinical trials are needed.

Occult pneumothorax in patients with abdominal trauma: CT studies.

Abdominal CT, which routinely includes the lower thorax, is an important adjunct to supine chest radiography in detecting chest injury in patients with blunt abdominal trauma. In 1,086 consecutive patients with blunt abdominal trauma, 223 of whom had both supine chest radiography and abdominal CT, 49 patients examined with both techniques had pneumothoraces, 28 of them occult (seen only on CT). To help guide management, we established three categories of occult pneumothorax, based on size and location: (a) minuscule (< 1 cm in greatest thickness, seen on four or fewer images); (b) anterior (> 1 cm in greatest thickness, but not extending beyond the midcoronal line); (c) anterolateral (extending beyond the midcoronal line). In our study four of six patients with minuscule pneumothorax, including one who required mechanical ventilation, were observed without complications; two of six patients had chest tube placement. Seven of 14 cases with anterior pneumothorax were observed and resolved without complication; seven had chest tube placement. All eight patients with anterolateral pneumothoraces underwent percutaneous tube thoracostomy, regardless of proposed management.

Spinal implants and radiation therapy: the effect of various configurations of titanium implant systems in a single-level vertebral metastasis model.

BACKGROUND: The combination of surgery and radiation therapy is a common clinical practice in the treatment of spinal tumors. Although it is known that metallic implants disturb radiation therapy beams, it is not known what kind of dose distributions appear with spinal irradiation in the presence of a spinal implant. The aim of the present study was to investigate the effect of various spinal implant constructs on the dose of radiation delivered to the spinal canal in a single-level metastasis model. METHODS: We performed four spinal implant reconstructions on standard sawbones spine models: posterior instrumentation without anterior column reconstruction, posterior instrumentation with anterior column reconstruction with use of a titanium cage, anterior instrumentation with anterior column reconstruction with use of a titanium cage, and anterior instrumentation with anterior column reconstruction with use of chest tubes filled with bone cement. Irradiation with two different radiation therapy units (a cobalt-60 teletherapy unit and a linear accelerator) was performed twice for each model in a posterior-to-anterior direction, and thermoluminescent dosimeters were used to measure the dose changes in the anterior, middle, and posterior portions of the spinal canal. RESULTS: Compared with the sawbones-only model, the posterior instrumentation reconstructions resulted in a 5% to 7% decrease in the radiation dose delivered to the spinal canal with both radiation therapy units, whereas the anterior instrumentation reconstructions resulted in a 1% decrease in the dose delivered with the linear accelerator unit and a < or = 2% increase in the dose delivered with the cobalt-60 teletherapy unit. When thermoluminescent dosimeters in the middle of the spinal canal were evaluated individually, anterior instrumentation with anterior column reconstruction with use of bone cement-filled chest tubes resulted in a 5.5% increase in the radiation dose delivered with the cobalt-60 teletherapy unit, whereas all of the other instrumentation models resulted in a <1% disturbance in the radiation dose delivered with both radiation therapy units. CONCLUSIONS: The posterior instrumentation systems did not result in the delivery of an increased dose of radiation to the spinal cord, suggesting that current radiation therapy regimens may be performed without additional harm. The anterior instrumentation systems also appeared to be relatively safe when irradiation was performed with the linear accelerator unit. However, when irradiation was performed with use of the cobalt-60 teletherapy unit, there was an increase in the dose of radiation delivered to the spinal canal in the presence of the anterior instrumentation systems, particularly the anterior column reconstruction with use of bone cement-filled chest tubes. These dose-perturbation characteristics might be important to consider during the calculation of radiation therapy protocols for patients who are going to receive high doses or recurrent treatments that would reach the tolerance limits of the spinal cord.

Combined transthoracic and transtracheal closure of large bronchopleural fistulae.

PURPOSE: Postoperative central bronchopleural fistulae (BPF) are difficult to close using percutaneous or endoscopic techniques. We devised an alternative method to treat BPF using a combined transthoracic and transtracheal approach with the use of a multifilamented polypropylene (Prolene) mesh patch. METHODS: Two patients with large, central BPF after thoracic surgery and lobar resection had minimally invasive BPF closure using a transtracheal approach with catheterization of the fistula and thoracoscopically guided Prolene mesh placement over the bronchial stump defect. This technique was adopted after conservative management and multiple endobronchial interventions had failed in both patients. RESULTS: One patient had closure of his BPF within one week and remains symptom-free one year after chest tube removal. The other patient had a BPF and chest tube for two years prior to our procedure. His BPF initially closed, but recannalized 2 weeks later. He subsequently had two thoracotomies and continues to suffer a BPF which remains externalized to his chest wall. CONCLUSIONS: Post-thoracotomy central BPF that is resistant to nonsurgical treatments can be closed with a combined thoracoscopic and transtracheal placement of a polypropylene patch. The success of this repair seems to depend on early intervention and aggressive sterilization of the pleural space.

Percutaneous CT-guided radiofrequency ablation of pulmonary malignant tumors: preliminary report.

OBJECTIVE: Radiofrequency ablation (RFA) is frequently used for hepatic malignant tumors, but few reports discuss its use for lung tumors. We report our pilot clinical study with RFA for the treatment of pulmonary malignant tumors. PATIENTS AND METHODS: Five patients with histologically-proven malignant primary and three metastatic lung tumors underwent a total of 11 RFA procedures. RFA was performed in two patients as palliative therapy to shrink the tumors and in six as radical therapy. All RFA was performed by the percutaneous CT-guided approach. RESULTS: Three tumors were completely ablated by one procedure. Contrast CT revealed cyst cavity formation or scar formation at these three tumors. Gd contrast-enhanced MRI revealed cystic lesions with ringlike enhancement or scar formation. Partial ablation after the first procedure was noted in six tumors including the two palliative cases. RF ablation was well tolerated in all patients. Intraprocedural complications included six cases of pneumothorax (one patient required chest tube placement), six cases of pleural effusion (two patients required chest tube placement), one case of pneumonia (improved immediately with antibiotics), three cases of bloody sputum (mild), and six cases of chest pain (all cases after the procedure). CONCLUSIONS: This pilot clinical study demonstrates that CT-guided RFA is a relatively safe and effective treatment option for malignant lung tumors. Additional trials are needed to determine the safety, efficacy, and optimal indications of RFA.

Hemothorax and chylothorax.

Hemothorax and chylothorax remain perplexing medical problems. The primary cause of hemothorax is trauma, whereas the primary cause of chylothorax is cancer. Most patients with hemothorax can be treated with chest tube drainage only. Early thoracotomy with thoracic duct ligation is recommended for patients with chylothorax when conservative treatment with chest tube drainage and hyperalimentation fails. Radiation therapy is the mainstay of treatment for chylothorax related to cancer. Video-assisted thoracoscopy may play an increasing role in the surgical treatment of both hemothorax and chylothorax.
