Video-assisted thoracoscopic talc pleurodesis is effective for maintenance of peritoneal dialysis in acute hydrothorax complicating peritoneal dialysis.

BACKGROUND: Acute, massive, unilateral hydrothorax is an uncommon but well-recognized complication of peritoneal dialysis. Its clinical course and treatment outcome after a recently advocated technique of video-assisted thoracoscopic (VATS) talc pleurodesis remains unclear. METHODS AND RESULTS: Between July 1998 and March 2002, among 475 CAPD patients in two regional hospitals in Hong Kong, nine patients (three men, six women, mean age 53+/-12 years) developed acute hydrothorax due to pleuroperitoneal communication (R=8, L=1) within 5.8+/-4.2 months (median, 5.2 m; range, 2 days to 11.6 months) of commencing peritoneal dialysis. Analysis of simultaneously obtained peritoneal and pleural fluid in all subjects only showed concordance in protein content (consistently<4 g/l), while fluid glucose and lactate dehydrogenase levels were not comparable. The methylene blue test was negative (n=4). Radionuclide scan (n=6) and contrast CT peritoneography (CTP, n=3) detected pleuroperitoneal communication in half and one-third of the patients, respectively. All patients underwent pleurodesis achieved by talc insufflation into the pleural cavity under VATS guidance. All patients were successfully returned to peritoneal dialysis. After a mean follow-up of 18.8+/-12.5 months, hydrothorax recurred in one patient (at 7 months after pleurodesis), who was successfully treated by repeating the procedure. CONCLUSIONS: Hydrothorax complicating CAPD is more commonly right-sided, and tends to occur within the first year of starting peritoneal dialysis. Isotope scan and CTP are insensitive in diagnosing pleuroperitoneal communication. A low pleural fluid protein content is the most consistent biochemical finding. VATS talc pleurodesis is a safe and reliable treatment of choice that allows sustained continuation of CAPD with low recurrence rate.     

Palliative treatment of malignant pleural effusions by video-assisted thoracoscopic surgery

Malignant pleural effusion (MPE) are associated with significant morbidity. Prompt clinical evaluation followed by aggressive treatment often results in successful palliation. Video-assisted Thoracic Surgery (VATS) today can be employed in the diagnosis and treatment of idiopatic and known MPE. Between January 1994 and December 1998 233 MPE patients were treated with pleurodesis. 206 of them underwent tube thoracostomy and drainage alone followed by chemical pleurodesis. In 27 out of the 233 cases VATS management was applied. These patients had undiagnosed pleural effusions or recurrent MPE following failed previous drainage and pleurodesis. The cause of the effusion was breast cancer in 11 patients, lung cancer in 9, urogenital cancer in 3, mesothelioma in 2 and other in 2. VATS intervention was thoracoscopic exploration with biopsy and directed chemical sclerosis in undiagnosed MPE (19/27) and lysis of pleural adhesions with partial decortication and pleurodesis in recurrent effusions (8/27). VATS managements were successful 26/27 after mean follow up of 6 months. Had not mortality postoperatively and severe morbidity. Chest tubes were removed 1.5 +/- 0.5 days postoperatively and hospital stay were averaged 4 +/- 1 days. We concluded that VATS is a safety and effective way of managing selected patients with pleural effusions.     

Long-term follow-up of thoracoscopic pleurodesis for hydrothorax complicating peritoneal dialysis

BACKGROUND: Massive hydrothorax is a significant complication of continuous ambulatory peritoneal dialysis (CAPD) and its ideal management remains undefined. Conservative management in the form of intermittent peritoneal dialysis had limited success. The use of conventional pleurodesis and open thoracotomy were associated with morbidities and limitations. We retrospectively reviewed the long-term outcome of 8 patients with massive hydrothorax complicating CAPD, 6 of whom received thoracoscopic pleurodesis. METHODS: Among 397 patients undergoing continuous ambulatory peritoneal dialysis during the period from 1994 to 1998, hydrothorax developed in 8 patients. Four patients were first treated with temporary intermittent peritoneal dialysis using 1-L exchange cycles. Three of them had a recurrence of the hydrothorax whereas only one could resume continuous ambulatory peritoneal dialysis successfully. Two patients then underwent conventional pleurodesis but failed. One of them was switched to hemodialysis. Thoracoscopic pleurodesis was performed for the remaining 2 patients together with 4 other patients with hydrothorax once this complication developed. There were no gross abnormalities including pleuroperitoneal communication sites identified. Talc poudrage was performed in 2 patients and mechanical rub pleurodesis in the other 4 patients. All had uncomplicated procedure and uneventful recovery. RESULTS: One patient after thoracoscopic pleurodesis was soon switched to hemodialysis for an unrelated reason. The other 5 patients resumed continuous ambulatory peritoneal dialysis with no recurrence of hydrothorax for a mean period of 50 months (range 19 to 84). CONCLUSIONS: With thoracoscopic pleurodesis, patients resumed continuous ambulatory peritoneal dialysis without recurrence of hydrothorax on long-term follow-up.     

Primary treatment of malignant pleural effusions: video-assisted thoracoscopic surgery poudrage versus tube thoracostomy

The objective of this study is to show that primary treatment of malignant pleural effusions secondary to ovarian carcinoma with video-assisted thoracoscopic surgery (VATS)-assisted talc poudrage (VATS-ATP) results in shorter hospital stays and reduced time with a chest tube than primary treatment with a chest tube and chemical pleurodesis. We conducted a retrospective chart review of all patients with a symptomatic pleural effusion secondary to primary ovarian carcinoma receiving intervention from January 1996 to December 2000. Patients either received tube thoracostomy with pleurodesis (n = 22) or VATS-ATP (n = 12). Of the patients treated with tube thoracostomy 18 per cent (4/21) died in the hospital before pleurodesis, 77 per cent (14/19) had successful pleurodesis, and 22 per cent (4/18) failed pleurodesis requiring VATS-ATP. In the group treated primarily with tube thoracostomy the chest tube was in place 8.36 +/- 2.61 days with a hospital stay of 12.64 +/- 5.80 days after the procedure. In the group treated with VATS-ATP there was 100 per cent successful pleurodesis. There were no mortalities. There was one prolonged intubation of 3 days and one incomplete lung reexpansion. The chest tube was in place for 4.58 +/- 1.78 days and a hospital stay of 7.50 +/- 4.12 days postprocedure. Groups treated by tube thoracostomy and VATS were statistically different; P < 0.001 for days with a chest tube and P = 0.011 for hospital days. We conclude that both tube thoracostomy with chemical pleurodesis and VATS-ATP provide adequate treatment of ovarian carcinoma-associated malignant pleural effusions. VATS-ATP provides a shorter duration of chest tube placement and postprocedure hospital stay.     

Video-assisted thoracoscopic esophagectomy for esophageal cancer

BACKGROUND: The Ivor-Lewis procedure is a radical, invasive, and effective procedure for the resection of most esophageal cancers. To minimize invasiveness, we performed thoracoscopic and video-assisted esophagectomy and mediastinal dissection for esophageal cancer. METHODS: From November 1995 to June 1997, 23 patients with intrathoracic esophageal cancer, excluding T4 cancers, underwent thoracoscopic and video-assisted esophagectomy. Bilateral cervical dissections were performed as well as preparation of the gastric tube and transhiatal dissection of the lower esophagus. The cervical esophagus was cut using a stapler knife, and esophageal reconstruction was performed through the retrosternal route or anterior chest wall. Next, thoracoscopic mediastinal dissection and esophagectomy were performed. RESULTS: The mean volume of blood loss was 163 +/- 122 ml; mean thoracoscopic surgery duration, 111 +/- 24 min; mean postoperative day for patients to start eating, 8 +/- 3 days; and mean hospital stay, 26 +/- 8 days. No patient developed systemic inflammatory response syndrome postoperatively. Tracheal injury occurred and was repaired during the thoracoscopic approach in one patient. No patients died within 30 days after surgery. Postoperative complications included transient recurrent nerve palsy in five patients, pulmonary secretion retention requiring tracheotomy in two, and chylothorax in one. Five patients died of cancer recurrence within 1 year of surgery. CONCLUSIONS: Our surgical experience with thoracoscopic and video-assisted esophagectomy indicate that it is a feasible and useful procedure.     

Efficacy study of video-assisted thoracoscopic surgery pleurodesis for spontaneous pneumothorax

BACKGROUND: This study aims to assess the efficacy of video-assisted thoracoscopic surgery pleurodesis in the treatment of spontaneous pneumothorax with particular reference to the rate of recurrence after abrasion pleurodesis and postoperative neuralgia. METHODS: One hundred one patients who underwent 109 video-assisted thoracoscopic surgery pleurodesis procedures in the Austin & Repatriation Medical Centre between January 1992 and June 1998 were identified from a computerized database. The follow-up period was from 8 months to 7 years and 1 month (mean, 44.4 months). Patients were telephoned and asked as to whether recurrence occurred, and if so, when it occurred and how it was treated. They were asked to grade their current pain level from 0 to 6. RESULTS: Eighty-two patients were contacted, corresponding to 88 video-assisted thoracoscopic surgery pleurodesis procedures that were followed up (80.7%). There were five recurrences (5.7%). The pain level was rated as 0 in 64 cases (72.7%), 1 in 27 cases (23.9%), 2 in 1 case (1.1%), and 3 in 2 cases (2.3%). CONCLUSIONS: These data suggest that video-assisted thoracoscopic surgery pleurodesis is a valid alternative to thoracotomy with pleurectomy for treatment of spontaneous pneumothorax with an acceptable recurrence rate and minimal amount of postoperative neuralgia.     

Thoracoscopic talc pleurodesis for recurrent, symptomatic pleural effusion following cardiac operations

Seventeen patients who underwent a cardiac operation developed a recurrent, symptomatic pleural effusion ultimately requiring video-assisted thoracic surgery (VATS) and talc pleurodesis. These patients represented 0.4% of all patients undergoing a cardiac operation over the same time period. Compared with an age- and sex-matched control group of cardiac surgery patients, patients requiring VATS for recurrent pleural effusion were more obese with higher body mass index (31.9 +/- 1.2 versus 28.3 +/- 1.4 kg/M2, P = 0.03), were more likely to have undergone a complex cardiac operation (8/17 versus 1/17, P =.01) and were more frequently on anticoagulation and antiplatelet agents besides aspirin (8/17 versus 2/17, P =.02). Patients underwent 1.86 +/- 0.34 thoracenteses with drainage of 846 +/- 166 mL/thoracentesis prior to referral for VATS. On average, patients underwent VATS 4.83 +/- 1.49 months after their cardiac operation. There were 3 VATS-related complications (17.6%) and no deaths. VATS talc pleurodesis led to symptomatic and radiologic improvement in all patients with a mean follow-up of 8.2 +/- 1.5 months. VATS talc pleurodesis effectively and safely treats the unusual postcardiac surgery patient with refractory pleural effusion.     

Video-assisted thoracoscopic management of recurrent primary spontaneous pneumothorax after prior talc pleurodesis: a feasible, safe and efficient treatment option.

OBJECTIVE: To assess the role of video-assisted thoracoscopic surgery (VATS) in the management of a recurrent primary spontaneous pneumothorax after a prior talc pleurodesis. METHODS: From 1996 to 2002, we retrospectively reviewed all patients who were treated for a recurrent primary spontaneous pneumothorax after a previous talc pleurodesis. Data on the talc procedure and the recurrent pneumothorax, delay between both, and operative features were studied. Conversion rate to a thoracotomy and postoperative complications as well as long-term outcome were reported. RESULTS: We collected 39 patients (28 male) with a median age of 25 years (15-41 years). The initial procedure consisted of thoracoscopic talc poudrage in all cases. The median delay between the talc procedure and the recurrence was 23 months [10 days-13 years]. Size of recurrence involved 10-80% of the hemithorax. The VATS procedure was successfully achieved in 27 patients (69%) while 12 required conversion to a thoracotomy. The main cause for conversion was the presence of dense pleural adhesion at the mediastinal part of the pleural cavity. Postoperative morbidity was limited to pleural complications in the VATS group (n=6, 22%). Median follow-up was 26 months [10-38 months]. One patient treated by VATS developed a partial recurrent pneumothorax at 12 months with a favorable outcome without further surgery. CONCLUSIONS: Feasibility, safety and efficacy of VATS for management of recurrent primary spontaneous pneumothorax following thoracoscopic talc poudrage are strongly suggested.     

Life expectancy of patients with malignant pleural effusion treated with video-assisted thoracoscopic talc pleurodesis

The aim of the current study was to analyse postoperative complications and survival after video-assisted thoracoscopic (VATS) talc pleurodesis for malignant pleural effusion. All patients with morphologically proven malignant pleural effusion who underwent VATS talc pleurodesis from November 1995 to November 2002 were included in retrospective analysis. VATS was performed in general anaesthesia and 5 g of asbestos-free talc was insufflated into the pleural cavity. Postoperative pleural drainage was used until fluid output was less than 100 ml/24 h. Ninety-eight patients (28 male and 70 female) with mean age 59.6 (range 18-82) years were included. Thirteen patients had a bilateral pleural effusion. The most common primary cancer sites were lung (30 cases), breast (25) and ovarium (11). Average duration of the operation was 46 (range 10-120) min. Median duration of postoperative drainage was 3 (range 1-20) days and postoperative hospitalisation 7 (range 3-70) days. Twenty-eight patients had postoperative complications (fever in 17 cases). In seven cases pleurodesis was ineffective. Median survival was 8.4 months. Six-, 12- and 24-month survival was 58% (95% CI [0.47-0.67]), 39% [0.29-0.49] and 20% [0.12-0.29], respectively. Survival data after VATS talc pleurodesis advocate use of this invasive treatment method despite the advanced stage of cancer.     

Ipsilateral recurrence frequency after video-assisted thoracoscopic surgery for primary spontaneous pneumothorax.

OBJECTIVE: We retrospectively evaluated the results of video-assisted thoracoscopic surgery for primary spontaneous pneumothorax and recurrence. METHODS: A series of 424 patients with primary spontaneous pneumothorax were treated by video-assisted thoracoscopic surgery-289 with an ipsilateral recurrent episode, 88 with persistent air leakage for 7 days or longer, 34 with a contralateral episode, 9 with hemopneumothorax, and 4 with tension pneumothorax. The commonest management was stapling of an identified bleb, undertaken in 375 patients (88.4%). Pleural abrasion was conducted in 250 (59.0%), but the abraded area was one-third or less of the thoracic cavity in 187 (74.8%). RESULTS: No operative deaths occurred. Revisional thoracotomy was required in 1 patient with postoperative bleeding and another with incomplete postoperative lung reexpansion; 26 had prolonged air leakage, but none required revisional thoracotomy. During a mean follow-up of 31.4 months, ipsilateral pneumothorax recurred in 40 patients (9.4%), with 26 (65.0%) having recurrence within 1 year postoperatively. A video-assisted thoracoscopic surgery was conducted again in 8, and thoracotomy in 14. CONCLUSIONS: The ipsilateral recurrence of primary spontaneous pneumothorax after video-assisted thoracoscopic surgery was high at 9.4%. If video-assisted thoracoscopic surgery is to be considered as a treatment for spontaneous pneumothorax, we must therefore reduce postoperative ipsilateral recurrence by training practitioners not to overlook blebs during the procedure and/or consider widening the area of pleurodesis.     

CAN SERUM INFLAMMATORY PARAMETERS ESTIMATE OUTCOME OF PLEURODESIS IN MESOTHELIOMA?

BACKGROUND: As pleurodesis causes systemic inflammation and is associated with considerable cost and morbidity during long-term follow up, the identification of patients who will experience an unsuccessful pleurodesis would be desirable. This study was aimed to investigate whether systemic inflammatory reaction induced by insuflation of talc into the pleura can predict the outcome of pleurodesis. METHODS: A total of 58 consecutive patients (26 men, 32 women) with malignant pleural mesothelioma underwent video-assisted thoracoscopy under general anaesthesia with monopulmonary ventilation between the years 2003 and 2006. Four grammes of asbestos-free and sterile talc were insuflated into the pleural space under direct vision. To assess the success of pleurodesis, chest radiographs were obtained at the 8th and 30th postoperative days. Venous blood samples were drawn both on admission and at the 24th hour after pleurodesis for the analysis of white blood cells, erythrocyte sedimentation rate and C-reactive protein. RESULTS: The mean age (standard deviation) of patients was 59.0 +/- 12.0 years. Pleurodesis was achieved (no effusion on chest radiograph) in 43 of 58 patients (74.1%)(group I), whereas it was unsuccessful in the remaining 15 patients (25.9%)(group II). There was a significant difference between two groups for basal and postpleurodesis levels of measured inflammatory parameters, C-reactive protein and erythrocyte sedimentation rate (for each, P < 0.05). However, the difference was not significant for white blood cells between the groups. CONCLUSION: Serum levels of inflammatory parameters (C-reactive protein and erythrocyte sedimentation rate) may be used to predict the success of pleurodesis in patients with malign mesothelioma who underwent thoracoscopic talc poudrage.     

RESULTS OF VIDEO ASSISTED THORACOSCOPIC PLEURODESIS IN MANAGEMENT OF PNEUMOTHORACES

The objective of the study is to find out the efficiency of video assisted thoracoscopic (VATS) pleurodesis and predisposing factors of postoperative complications. This is a retrospective study that those who had VATS pleurodesis from January 1994 to December 2000 were recruited. There were consecutive 306 VATS pleurodesis performed on 271 patients. These included 33 female and 238 male patients from 15 to 73 years old. 31 of them had bilateral procedures. 244 of them had primary spontaneous pneumothoraces and 27 of them had secondary pneumothoraces. Most of them had two or more episodes of pneumothoraces and persistent air leakage >14 days before operations. 15 patients had failed surgical or chemical pleurodesis before VATS. There was no operative death. Usually they were discharged within five days after operations. There were 21 persistent air leakage >5 days (6.8%), 1 bleeding required surgical haemostasis (0.3%) and 4 infectious complications (1.3%). Follow up duration was up to 72 months. There was 12 recurrence (3.9%) after discharge. Absence of blebs, presence of pleural adhesion, prolonged chest tube placement before VATS pleurodesis, and failed surgical or chemical pleurodesis before are the predisposing factors of complications.     

Additional mechanical pleurodesis after thoracoscopic wedge resection and covering procedure for primary spontaneous pneumothorax

Background  Additional mechanical pleurodesis for the treatment of primary spontaneous pneumothorax (PSP) is believed to reduce the recurrence of PSP, and a covering procedure with absorbable mesh also shows comparable results. This study was conducted to determine whether additional mechanical pleurodesis would be effective in reducing recurrence after thoracoscopic wedge resection and covering procedure. Materials and methods  Between May 2003 and August 2005, 99 patients underwent thoracoscopic bullectomy with staple line covering with absorbable cellulose mesh and fibrin glue followed by an additional mechanical pleurodesis. These patients were compared with 98 patients who underwent thoracoscopic bullectomy with staple line coverage alone. Results  The additional mechanical pleurodesis group had findings comparable to those of the coverage group for duration of postoperative chest drainage, length of hospital stay, and complication rate. After median follow-up of 29.2 months, postoperative recurrence occurred in four patients (4.0%). Conclusions  Additional mechanical pleurodesis after covering procedure is also effective in decreasing postoperative recurrence of PSP.     

Video-assisted thoracoscopic pleurodesis for malignant pleural effusions

AIM: The objective was to analyse the efficiency, and safety of thoracoscopic pleurodesis (TP). A retrospective study was made of an initial series of 75 patients undergoing lifetime follow-up who received TP in our department for the treatment of malignant pleural effusions (MPE). MATERIAL AND METHODS: From May 1994 to December 1998, 34 men and 41 women with a median age of 63.4 +/- 12.5 years were treated by TP. We performed 36 partial diathermic abrasions on pleura combined with talc insufflation, and in 39 cases only talc poudrage. The mean duration of insention of the chest tube was 4.1 (range 2 to 17) days, with 8.4 (range 5 to 20) days of postoperative hospitalization. There were no severe intraoperative or postoperative complications. The 30-day mortality rate was 1.3% (1 case). The period of follow-up ranged from 2.5 to 40 months (average 6.8). No case of late recurrence has been observed to date. CONCLUSION: Videothoracoscopic pleurodesis (talc poudrage) as a simple and efficient procedure seems to be the best alternative treatment regimen for the management of MPE in a group of selected patients.     

Thoracoscopic treatment of spontaneous pneumothorax in children

Background/purpose

This study describes the authors experience and results with thoracoscopic treatment of spontaneous pneumotrorax (SP) in 22 children.

Methods

A total of 32 thoracoscopic procedures were performed in 22 children. The patients ranged in age from 9 to 21 years at the time of their first thoracoscopy. SP was primary in 9 and secondary in 13 patients. Pleurodesis was performed in all thoracoscopies using talc in 28 and pleural abrasion in 4 procedures. In 2 of these, apical pleurectomy was added to abrasion. Blebectomy was the additional surgical procedure associated with pleurodesis in 4 patients.

Results

Thoracoscopy usually was performed with the patient under general anesthesia. In children with severe respiratory insufficiency, regional anesthesia was used. The mean operative time was 42.6 minutes (range, 8 to 114 minutes). The mean time of postoperative chest tube drainage was 4.6 days (range, 2 to 12 days). Three patients with cystic fibrosis had prolonged air leak lasting longer than 7 days after thoracoscopy. None of them required an additional surgical intervention, and the air leak ceased in 8, 8, and 12 days with continuous suction. One patient required a repeat thoracoscopy for bleeding from an intercostal artery on postoperative day one. The mean follow-up was 4 years (range, 2.5 months to 14 years). There have been 2 partial recurrences (6.25%), both in patients with secondary SP, which were treated by a repeat thoracoscopy and talc pleurodesis.

Conclusions

Thoracoscopic treatment of SP is safe and effective in children. It can be performed under regional anesthesia also in children with severe respiratory insufficiency. Because the complications and recurrences are encountered more frequently in children with an underlying lung disease, special care in surgical manipulation is required in this subgroup of patients with SP.     

Treatment of complicated spontaneous pneumothorax by simple talc pleurodesis under thoracoscopy and local anaesthesia

BACKGROUND: Complicated (recurring or persistent) spontaneous pneumothorax requires treatment either by talc pleurodesis with bullae electrocoagulation or, more aggressively, by thoracotomy or video- assisted thoracoscopic surgery. However, the relative merits of bullectomy, pleurectomy, and pleurodesis have not yet been established in the treatment of spontaneous pneumothorax. METHODS: The complications, duration of drainage, length of hospital stay, and immediate and long term success rate of treating complicated spontaneous pneumothorax with talc pleurodesis under local anaesthesia supplemented with nitrous oxide were studied. RESULTS: Talc pleurodesis was performed in 93 patients without serious complication (two benign arrhythmias, two subcutaneous emphysema, two pneumonia, one bronchospasm). The procedure was immediately successful in 90 patients (97%) with a median duration of drainage of five days (range 2-40) and a median length of hospital stay of 5.2 days (range 3-40). After a mean follow up duration of 5.1 (range 1-9.4) years in 84 cases the long term success rate was 95%, although six cases developed a small localised recurrence of spontaneous pneumothorax which did not require further surgery. Macroscopic staging at thoracoscopy was only carried out in the last 59 cases of whom 10 (17%) had bullae with a diameter of > 2 cm. In this group of patients the risk of definitive failure requiring surgery was significantly higher than in those patients without such bullae (odds ratio 7; confidence interval 3.7 to 13.3; p = 0.03), although eight of these patients did not require thoracotomy. Total lung capacity was reduced immediately after talc pleurodesis (mean (SD) 75 (23)% predicted at 10 days) but had improved to 95 (14)% predicted at 12 months. CONCLUSIONS: This study shows that simple thoracoscopic talc pleurodesis under local anaesthesia is a safe and effective treatment for complicated spontaneous pneumothorax. However, patients with bullae of > 2 cm in diameter have a greater risk of treatment failure.


     

A new technique of thoracoscopic pleurodesis for refractory hepatic hydrothorax

Background: Hepatic hydrothorax is defined as a pleural effusion that arises in patients with cirrhosis of the liver and no cardiopulmonary disease; it is believed to result from peritoneopleural communication through a defect in the diaphragm. Methods: Nine patients underwent thoracoscopic pleurodesis. The diaphragmatic defect was detected and corrected in two cases. In all patients, an argon beam coagulator was applied to the diaphragm surface, which was then completely covered with bioabsorbable prostheses. We then spread 3 ml of fibrin glue on the covered diaphragm and sprinkled 5 KE of OK-432 and 100 mg of minocycline hydrochloride in the thoracic cavity. Results: All patients showed clinical improvement. The pleural effusion and breathlessness resolved immediately after pleurodesis. There were two recurrences after 1 and 4 months, respectively. One of these patients improved after repeat pleurodesis; the other was treated conservatively. Conclusion: Our new technique of thoracoscopic pleurodesis is an effective and minimally invasive treatment for patients with refractory hepatic hydrothorax.

Combined surgery of intrapleural perfusion hyperthermic chemotherapy and panpleuropneumonectomy for lung cancer with advanced pleural spread: a pilot study

For the treatment of lung cancer with advanced pleural spread, aggressive local treatment could offer a chance of cure. This study evaluates the early and midterm results of our Phase I trial for the new modality of two-stage approach combining thoracoscopic intrapleural perfusion hyperthermic chemotherapy (TIPHC) and panpleuropneumonectomy for the disease. Five patients were enrolled in this study. All had proven lung cancer with major malignant pleural effusion or numerous pleural dissemination. The combined regimen was planned first with TIPHC using high doses of cisplatin, followed by a second stage with panpleuropneumonectomy with full-thoracotomy approach as radical surgery. All patients successfully completed this treatment, and there were no serious complications. Panpleuropneumonectomy was performed 14+/-1.2 days after TIPHC, and the mean operation time was 280+/-35 min, the blood loss was 620+/-89 ml. One patient with pathological N2 developed liver metastases 8 months after surgery and died. The other four patients are living and have not experienced any recurrence to date. The mean survival time is 19 months, and the longest is 32 months. Our new treatment modality is feasible and seems to provide a possibility for safe and effective radical local tumor control for patients of lung cancer with advanced carcinomatous pleuritis.     

Resection of neurogenic tumors in children: is thoracoscopy superior to thoracotomy?

BACKGROUND: Minimally invasive resection of solid tumors is controversial because of concerns of inadequate resection and local recurrence. Thoracoscopy has been used in the diagnosis of mediastinal tumors in children, but its role in resection is unproved. The purpose of this study was to compare thoracoscopic and open approaches to the resection of thoracic neurogenic tumors in children. STUDY DESIGN: The tumor registry of a regional children's hospital was queried to identify patients who underwent resection of neurogenic tumors over a 6-year period. Thoracoscopic and open groups were compared for demographic, operative, oncologic, and outcomes characteristics. RESULTS: Seventeen children underwent resection of mediastinal neurogenic tumors (10 thoracoscopic resections, 7 open resections). Mean age was 4.7 years (range 6 months to 12 years). The thoracoscopic and open groups showed no difference in operative time or blood loss. Tumors in the two groups were comparable in size (5.2+/-2.2 cm versus 5.7+/-2.6 cm), histology, surgical margin, and stage. Hospital stay was shorter after thoracoscopic resection (1.9+/-0.7 days versus 4.1+/-2.5 days, p<0.05). There were no regional recurrences. Distant metastases developed in one patient in each group. Eight of 10 children with malignant tumors remain disease-free at an average of 25 months of followup (range 3 to 80 months). CONCLUSIONS: Thoracoscopic resection of neurogenic tumors achieved similar local control and disease-free survival when compared with open resection in this preliminary series. These results were accompanied by a shorter hospital stay. These findings suggest that thoracoscopic resection of neurogenic tumors in children may offer advantages to open resection and should be studied in the context of a large, cooperative trial.
