[Spontaneous pneumothorax: pleurodesis with an iodo-povidone hydroalcoholic solution].

OBJECTIVE: To analyze the efficacy of an iodo-povidone hydroalcoholic solution for the chemical pleurodesis of spontaneous pneumothorax. MATERIAL AND METHOD: A descriptive, retrospective study of 81 patients with spontaneous pneumothorax. The patients were treated by video-assisted thoracoscopy and chemical pleurodesis with an iodo-povidone hydroalcoholic solution at the thoracic surgery unit of Hospital de la Santa Creu i Sant Pau in Barcelona (Spain) between January 1993 and December 1999. RESULTS: Eighty-one patients, 59 men (73%) and 22 women (27%), between 14 and 82 years old (mean age 33 years) were treated. Pneumothorax was most often on the right side (43 cases, 53%). The main indications for surgery were recurrence (52 cases, 64%) and persistent air leaks (25 cases, 31%). All were treated by video-assisted thoracoscopy, with resection of the pulmonary parenchyma in 30 cases (37%) and pleural instillation of the iodo-povidone hydroalcoholic solution as the irritant in all cases. Air leaks were observed during early postoperative recovery in 10 patients (12.3%), self-limited fever in 5 (6.1%) and infection of drainage openings in 2 (2.4%). During the postoperative follow-up period of 6 to 67 months (mean 24 months), 5 recurrences (6.1%) were seen. CONCLUSIONS: An iodo-povidone hydroalcoholic solution is easy to apply by video-assisted thoracoscopy and is highly effective for pleurodesis in cases of spontaneous pneumothorax.

[Comparative study of different methods of pleural drainage in an experimental model of pneumothorax].

OBJECTIVE: To observe the usefulness of several procedures for draining pneumothorax in an animal model and to identify the best pleural drainage system with minimal impairment of respiratory function. METHOD: Thirty-four New Zealand white rabbits weighting 1687 +/- 78 g and aged a mean 59 days were randomly placed in groups as follows. Unilateral pneumothorax was induced in the first problem group (P1) rabbits (n = 10) by thoracostomy, with pleural drainage. In the second problem group (P2) of rabbits (n = 10), bilateral pneumothorax was similarly induced by thoracostomy with pleural drainage. The control groups underwent unilateral (C1; n = 7) and bilateral (C2; n = 7) thoracostomy and drainage. Every 7 minutes the chest tube was connected successfully in each animal to an underwater seal with a dead-space volume of 35.58 ml (neonatal Bülau unit) or to a 3,940 ml system (chest drainage unit) and to pleural aspirations of -5 and -20 cmH2O. We analyzed mortality, fluctuations of the hydrostatic column of the underwater seal, heart rate (HR), respiratory rate (RR), PaCO2, SaO2, pH and arterial blood gas measures. RESULTS: Intraoperative mortality was significantly higher (particularly in the P2 group) when connection was to a large volume system without aspiration. Recovery after pneumothorax was more satisfactory with aspiration of -5 and -20 cmH2O. CONCLUSIONS: The results suggest that a pleural drainage unit with a large dead space between the pleural cavity and the underwater seal is a frequent cause of respiratory failure or insufficiency. We believe that when an underwater seal without pleural suction is applied, the Bülau unit should be used with the smallest possible volume.

Spontaneous pneumothorax: consecutive treatment of a series of 45 cases. Preliminary results of using therapeutic videothoracoscopy.

The appearance of procedures derived from video assisted thoracoscopy (VAT) has fostered new breakthroughs in the treatment of spontaneous pneumothorax. Our early experience with a study protocol using this technique is described. Patients admitted to our hospital in 1995 with a diagnosis of spontaneous pneumothorax were enrolled consecutively. Diagnosis was based on symptoms and pneumothorax was quantified by measuring the interpleural distance observed on the chest film. The initial treatment was pleural drainage; VAT was ordered in cases of recurrence, when lung reexpansion failed or when air leakage was persistent. Forty-five cases (30 men, 15 women) are reported. Mean age was 29 years. Eleven (24%) patients had had earlier pleural drainage but were suffering recurrences. The right side was involved in 14 (54%) cases. Initial treatment was pleural drainage and in 32 cases no other treatment was given. VAT was performed on 11 patients. In 1 (9%) patient the procedure became a minithoracotomy, or video-assisted thoracoscopic surgery. In 2 patients conventional thoracotomy was performed. Mean time the procedure lasted was 80 min. Mean follow-up was 3 months. There were no recurrences among patients treated with VAT and surgery. Our initial experience demonstrates that VAT is the technique of preference for the definitive treatment of spontaneous pneumothorax. There is less postoperative pain, increased comfort, no noteworthy morbidity, shorter postoperative hospital stays and prompt return to normal activity for the patient; these advantages lead us to choose this treatment over open surgery.

Right pneumothorax with the S1Q3T3 electrocardiogram pattern usually associated with pulmonary embolus.

An 18-year-old man presented with a spontaneous right pneumothorax. An initial electrocardiogram (ECG) showed an S wave in lead I, a Q wave in lead III, and an inverted T wave in lead III. This ECG pattern, S1Q3T3, has been most often associated with pulmonary embolus. These changes resolved with partial reexpansion of the lung. Both right and left pneumothorax have been associated with ECG changes, including changes that mimic myocardial ischemia. Because the clinical presentation of pneumothorax may be similar to angina or pulmonary embolus, ECG changes with pneumothorax may lead to confusion in the diagnosis.

Primary spontaneous pneumothorax in Arabs: does its frequency differ from elsewhere?

No data are available on primary spontaneous pneumothorax (PSP) in Arabs. Hence we sought to determine its characteristics in Arabs of the Al-Ahmadi Governorate in Kuwait. All patients over 10 years of age with pneumothorax who were admitted to the only free general hospital serving Ahmadi area from 1985 to 1996 were reviewed retrospectively. The study included all patients' medical records, investigations, treatment, morbidity, and mortality. Any patient with secondary pneumothorax was excluded. Primary spontaneous pneumothorax was rare in female Arabs, as they are almost never smokers. There were only two females out of total 58 patients with an incidence of 0.3 per 100,000 per year. Its incidence in male Arabs was 8.8 per 100,000 per year, similar to that in other studies. The distribution had a monophasic pattern, the average age being 23 (+/- 7.3 SD) years at the first episode. Smoking, a tall, asthenic (slim, relatively weak in appearance, ectomorphic) body build, and a positive family history are the most important risk factors and are not different from most studies conducted in other parts of the world.

The impact of spontaneous pneumothorax, and its treatment, on the smoking behaviour of young adult smokers.

The pneumothorax, and its often invasive treatment, are impressive events in otherwise healthy young patients. The relationship between smoking behaviour and the idiopathic spontaneous pneumothorax (ISP) is explained to the patients. The objective of the study was to analyse whether smoking behaviour of patients is influenced by the ISP (re-) event, and its treatment. Of 145 consecutive ISP patients (1991-1995), 112 were tobacco smokers at time of the first ISP. Of the 112, 106 participated in a confidential telephone questionnaire survey combined with retrospective medical record analysis. Smoking cessation and reduction percentage related to ISP events, and its treatment, were the outcome measurements. All patients (mean age 28.8 years at the first ISP) were aware of the relationship between smoking, and ISP at time of the first ISP. Age, pack years, and different treatment modalities had no influence on smoking cessation or reduction. Some 86.2% of the male and 80.8% of the female patients continued smoking after the first ISP, despite the known relationship between smoking, and contracting spontaneous pneumothorax, and despite its often invasive treatment. In the group of recurrent pneumothorax events 73.3% continued smoking.

Incidence of chronic pain after minimal-invasive surgery for spontaneous pneumothorax.

OBJECTIVE: Recently, it has been shown that minimal-invasive surgical procedures like operations for spontaneous pneumothorax result in a reduction of pain in the immediate postoperative course. However, little is known on the influence of minimal-invasive thoracic surgery on long term disability. Therefore, we analyzed the incidence of chronic pain in patients after minimal-invasive operation for primary (PSP) or secondary (SSP) spontaneous pneumothorax. METHODS: In the study included were 78 patients (PSP: n=59; SSP: n=19; male: 58, female 20) who had been treated at our institution between 1992 and 1995. The median age was 37 years (range: 17-84). The patients were interviewed by a standardized questionnaire or alternatively by phone or in the outpatient clinic. Complete follow up data were obtained from 60 patients which were further analyzed. RESULTS: After a median follow up of 59 months (range 35-79) 41 (68.3%) patients were completely free from any complaints. However 19 (31.7%) patients suffered from chronic pain. Two of them (3.3%) required daily oral pain medication. The incidence of chronic complaints was more frequent in patients with pleurectomy (47.1%) as compared to patients with mechanical pleurodesis only (25.6%; P=0.107). On a visual analog pain scale (ranging from 0 to 100) five (8.3%) patients described a pain intensity <10, 12 (20%) patients between 10 and 20 and two (3.3%) patients >50. In the majority of the patients the pain was located in the area of the trocar incisions. Six (10%) patients had a chronic complaints in the ipsilateral shoulder. CONCLUSIONS: The incidence of chronic postoperative complaints after minimal-invasive procedures for spontaneous pneumothorax is relatively high. This has to be considered if minimal-invasive procedures are discussed to be an alternative to simple drainage therapy for the first episode of spontaneous pneumothorax.

Recurrences following videothoracoscopic treatment of primary spontaneous pneumothorax: the role of redo-videothoracoscopy.

OBJECTIVE: There is very little experience regarding recurrences following videothoracoscopic (VATS) treatment of primary spontaneous pneumothorax. We report our experience with 19 patients who underwent redo-VATS to evaluate the feasibility of such surgical approach. METHODS: From July 1, 1992 to September 1, 2000, out of 2136 VATS procedures performed at our institution, 597 patients (27.94%) underwent VATS treatment of primary spontaneous pneumothorax with a recurrence rate of 3.85% (23 cases). Primary VATS treatment in these patients was: talc poudrage, three cases; subtotal pleurectomy, three cases; ligation of the bullae + subtotal pleurectomy, 12 cases; stapling of the bullae + subtotal pleurectomy, two cases; ligation of the bullae + talc poudrage, one case; stapling of the bullae + talc poudrage, one case. Treatment of the 23 recurrences included: 15 redo-VATS, four standard thoracotomy, three pleural drainage, one bed rest. Four additional redo-VATS were also performed in four patients operated on in different institutions. Redo-VATS showed residual bullae in nine cases and a minimal leaking area in one patient; in the remaining nine patients no lesion was found. Redo-VATS treatment was: stapling of the bullae + talc poudrage in nine patients; suture of the leaking area with a no-knife stapler + talc poudrage in one patient; isolated talc poudrage in the remaining nine patients with no-evidence of bullae or blebs. RESULTS: No mortality was reported; no major complications occurred. The conversion rate in the group of redo-VATS was 5.2% (one patient). At a mean follow-up of 32 months no patient showed recurrent pneumothorax. CONCLUSIONS: In the light of our initial experience, redo-VATS seems to be a promising tool for the surgical therapy of recurrences following VATS treatment of primary spontaneous pneumothorax.

Is video-assisted thoracic surgery justified at first spontaneous pneumothorax?

OBJECTIVE: The fundamental role of video-assisted thoracic surgery (VATS) in the treatment of spontaneous pneumothorax is generally acknowledged today. This study intends to evaluate whether VATS is justified at the onset of a first spontaneous pneumothorax through analysis of parameters tested on two group of patients treated respectively with pleural drainage and VATS. PATIENTS/METHODS: The study includes 70 patients affected by first spontaneous pneumothorax divided into two groups of 35 patients for the purpose of therapeutic treatment. The first group underwent pleural drainage while the second underwent VATS. Parameters analyzed were as follows: (1) prolonged air leaks (more than 6 days); (2) time required for pleural drainage; (3) time of hospital stay; (4) management costs; (5) recurrences (follow-up at 12 months). RESULTS: Prolonged air leaks occurred in four patients (11.4%) in the first group and two patients (5.7%) in the second; recurrences occurred in eight patients in the first group (22.8%), and only one in the second group (2.8%). Mean time for drainage and hospitalization was, respectively, 9 and 12 days in patients with pleural drainage against 3.9 and 6 days of those using VATS. Average management costs per patients including hospitalization was calculated at $2,750.00 per patient for the first group compared with $1,925.00 for the second group. CONCLUSIONS: The use of VATS at first spontaneous pneumothorax is justified in the interest of both patients and health administrations as demonstrated by the number of recurrences in patients in the first group and economy savings resulting from use of VATS.

Does a thoracoscopic approach for surgical treatment of spontaneous pneumothorax represent progress?

OBJECTIVE: Surgical management is indicated in recurrent forms of pneumothorax and for failure of tube drainage. We have for several years performed pleurodesis and apical blebs stapling by axillary thoracotomy. Thoracoscopy has been a well established procedure for 70 years and recently further developed as the result of current technological progress. For 10 years thoracoscopy has been developed as an alternative to thoracotomy in several indications. Spontaneous pneumothorax is ideally suitable for thoracoscopic management. The aim of this retrospective study is to evaluate this new approach. METHODS: We compare our results of axillary thoracotomy management of spontaneous pneumothorax in 237 patients (group 1) with those of thoracoscopic management in 101 patients (group 2). Sex distribution, average age, indications and stapling of apical blebs were comparable in both groups. RESULTS: Etiologies were comparable in both groups. The average operation time was 71 min in group 1 and 57 min in group 2. The average duration of chest tube placement was 8 days in group 1 and 6.5 days in group 2. The mean hospital stay was 14 days in group 1 and 9.5 days in group 2. The overall morbidity was 16 and 11% in groups 1 and 2, respectively. The most frequent complication was early or late failure of pleurodesis which required second drainage or a subsequent operation. Late failure occurred more frequently after thoracoscopy (3 vs. 0.4%) but there was no statistically significant difference between the two groups. CONCLUSIONS: Thoracoscopic management of spontaneous pneumothorax is a safe procedure. Moreover, it offers the benefits of a shorter hospital stay and less postoperative pain.

Resolution of native lung pneumothorax by insertion of a nitinol stent for bronchostenosis in the transplanted lung.

Following single lung transplantation, the native lung remains a potential source of morbidity from spontaneous pneumothorax, hyperinflation, bacterial and fungal infection and malignancy. The case of a single lung transplant recipient for idiopathic pulmonary fibrosis who developed a recurrent, non-resolving, spontaneous multiloculated pneumothorax in the native lung following thoracoscopic talc pleurodesis is reported. The pneumothorax ultimately resolved following insertion of a nitinol stent for coexisting bronchostenosis in the transplanted lung. In a single lung transplantation recipient in whom a native lung pneumothorax reoccurs or persists despite appropriate initial management, it may be useful to undertake bronchoscopy to exclude the possibility of bronchostenosis in the transplanted lung.

Treatment of pneumothorax in newborns: use of venous catheter versus chest tube.

BACKGROUND: The traditional treatment for pneumothorax is tube thoracostomy. Chest tube placement often involves complications, particularly in newborns. The aim of this study is to introduce the method of air drainage with venous catheter and to compare two different methods, chest tube placement and venous catheter insertion, in the treatment of pneumothorax in newborns. METHODS: We treated 72 newborn patients with pneumothorax over a 4-year period in neonatal intensive care units at two different medical centers. We randomly divided the patients into two groups. In group I, we treated the patients with chest tube placement technique. We used 18-gauge venous catheter connected to an underwater system to drain air in group II patients. The duration of the procedure, the period of time that the chest tube or catheter was left in place, and the complications associated with the two different procedures were statistically compared. RESULTS: The time required to perform the venous catheter procedure was significantly shorter than that for chest tube placement (P < 0.05). The duration of the device in place was also significantly shorter in group II than group I (P < 0.05). Only two minor complications were recorded in patients who underwent venous catheter placement, and this group's complication rate was significantly lower than the rate in the chest tube group (P < 0.05). CONCLUSION: Insertion of a venous catheter is a safe alternative to chest tube placement as a method of draining air from newborn patients with pneumothorax. This is an easy and quick bedside procedure and is particularly useful for newborn patients that require immediate air drainage.

Cardiac output increases prior to development of pulmonary edema after re-expansion of spontaneous pneumothorax.

Pulmonary edema following reexpansion of spontaneous pneumothorax is an uncommon complication. The underlying mechanism of this condition is unclear. We report the hemodynamic characteristics in a series of 7 male patients with spontaneous large (>50%) pneumothoraces of > or = 24 h and correlate the changes with reexpansion pulmonary edema (REPE). A pulmonary artery floatation catheter was inserted and hemodynamic data were obtained before therapeutic chest tube insertion, 1 h after chest tube insertion and the following day. Four (57%) patients developed REPE. There was a tendency for larger pneumothorax to develop REPE. Capillary wedge pressure did not change significantly 1 h after the insertion of chest tube in all our patients. Cardiac output increased significantly in patients who developed REPE compared to those who did not (+ 1.06 l/min vs -0.27 l/min; P = 0.03) 1 h after insertion of chest tube. One patient did not develop pulmonary edema despite having a large (> 80%) pneumothorax. His cardiac output did not rise 1 h after chest tube insertion. REPE is not an uncommon complication following chest tube drainage in patients with large and long-standing pneumothorax. The increase in cardiac output after chest tube insertion may be associated with subsequent development of REPE.

Chronic spontaneous pneumothorax decortication after 130 days.

The case of a 21-year-old male with neglected and protracted spontaneous pneumothorax is reported. Video-assisted thoracoscopy after 130 days showed the lung to be trapped solely by a thick pleurovisceral membrane, which required open surgical decortication. Chronic pneumothorax is a rare complication of spontaneous pneumothorax. This is the second report on a chronic pneumothorax solely due to a pleurovisceral membrane and the longest reported interval until decortication.

[Results of video-assisted thoracoscopic surgery for pneumothorax].

INTRODUCTION: Video-assisted thoracoscopic surgery has been used in the treatment of pneumothorax since 1990. There is still no general agreement regarding the procedure to obliterate the pleural space or regarding the indication for wedge resection if no blebs or bullae can be found. PATIENTS AND METHODS: Clinical records referring to 100 video- assisted thoracoscopic operations for pneumothorax, performed in Berlin-Buch between 1998 and 2001, were retrospectively evaluated with regard to the rate of recurrences and postoperative complications in connection with the operative procedure. There were 70 male and 28 female patients aged from 16 to 78 years. The mean age was 34 years. The statistical significance was evaluated by the McNemar-test. RESULTS: 74 patients showed a regular postoperative course. Severe postoperative complications occurred in 9 patients: re-operation via thoracotomy n=5 (postoperative bleeding n=2, recurrence n=2, persistent air-leak n =1); re-thoracoscopy n=3 (postoperative bleeding n=2, recurrence n=1), pleural empyema n=2. The complication rate was significantly higher (p < 0.001) in patients with underlying pulmonary diseases (secondary spontaneous pneumothorax) or thoracic surgery in their history. Depending on the intraoperative situation, the cause of pneumothorax and the patient's general condition the pleural space was obliterated by the following procedures: apical parietal pleurectomy (n=85), electro-pleurodesis alone (n= 7), electro-pleurodesis and pleural abrasion (n=3), talcum poudrage (n=2). The rate of major complications was lower (p < 0.001) when pleurectomy was performed 8.2 % (7/85) compared to those operations performed without pleurectomy 13.3 % (2/15). The rate of re-operations for recurrences/persistent air leaks or empyemas following persistent air leaks was significantly lower (p < 0.001) when wedge resection 3.75 % (3/80) had been performed compared with operations without wedge resection 10 % (2/20). DISCUSSION: Apical parietal pleurectomy and wedge resection of blebs or bullae are effective methods to prevent recurrences. Considering the specific complications of parietal pleurectomy alternative methods to obliterate the pleural space should be used depending on the intraoperative situation. Among other factors underlying pulmonary diseases or thoracic surgery in the patient's history strongly influence the postoperative outcome independently of the operative procedure.

Long-term results after video-assisted thoracic surgery for spontaneous pneumothorax.

OBJECTIVE: Analysis of the long-term results of video-assisted thoracic surgery (VATS) for spontaneous pneumothorax in patients treated in two surgical centres from May 1994 until December 2000. METHODS: A cohort of 86 patients was studied retrospectively. For final analysis, 74 patients undergoing 76 VATS procedures were included. RESULTS: Sixty-three procedures for primary spontaneous pneumothorax (PSP) and 13 procedures for secondary spontaneous pneumothorax (SSP) were performed. In 78.9% (n = 60) blebs or bullae were resected with an endostapler device. In 2.6% (n = 2) an apical fibrotic zone was resected. In 71.1% (n = 54) a subtotal pleurectomy was performed combined with an abrasion in 41 cases. In 21.1% (n = 16) a total pleurectomy and in 7.8% (n = 6) an abrasion was performed. Operative mortality was 1.3% (n = 1) and total operative morbidity 25.4% in the PSP group and 76.9% in the SSP group. Mean follow-up was 36 months. The global recurrence rate was 5.3% (n = 4), being 4.8% (n = 3) in the PSP group and 7.7% (n = 1) in the SSP group. Recurrences occurred at 1 (n = 2), 2 (n = 1) and 16 (n = 1) months after the initial operation. The incidence of postoperative neuralgia was 17.1% (n = 13). One patient needed analgesics for the neuralgia. CONCLUSION: VATS treatment of spontaneous pneumothorax proves to be effective. In cases of SSP, VATS treatment is feasible but a higher morbidity rate should be anticipated.

Spontaneous pneumothorax in children--a review of 95 cases.

We reviewed the records of 95 consecutive patients with spontaneous pneumothorax. The children, 75 boys and 20 girls, ranged in age from newborn to 12 years. The average duration of symptoms, cough, chest pain and breathlessness, was 5 days. Pyogenic lung infection (74.8%) and pulmonary tuberculosis (21%) were the commonest underlying causes of pneumothorax. All children underwent tube thoracostomy drainage along with supportive treatment. Five died owing to sever infection present at the time of admission. Except for the five (5.21%) who died, all children (94.79%) had full relief of pneumothorax. We conclude that pyogenic pulmonary infection and pulmonary tuberculosis are still the commonest causes of pneumothorax in the tropics. Tube thoracostomy drainage is very successful and thoracotomy in selected patients is safe.

Management of pneumothorax with a mini-drain in ambulatory and hospitalized patients.

OBJECTIVE: To test the clinical performance of a miniaturized drainage system and compare the effect on pain and mobility between the new system and a standard system. One aim was to try ambulatory treatment in patients with uncomplicated pneumothorax (35/55), another to see if patients with more severe diseases and pneumothorax could be mobilized better while in hospital. DESIGN: Follow-up of 55 patients treated with the new system. Detailed analysis of a subgroup of 20 of those patients compared with 17 patients treated with a standard system. RESULTS: No major complications occurred. Minor complications were haematomas and bleeding in three patients. In 12% the unit had to be replaced due to blockage by clots, obstruction of the tube, or sub-optimal performance. There were nine recurrences (16%), so patients had to have a standard drain or be referred for operation. In the subgroup of 35 patients with uncomplicated primary pneumothorax, 31 (88.5%) could be managed on an outpatient basis resulting in considerable cost reductions. Many of those patients could lead a normal life, including work during the treatment time. The new drain system was significantly less painful during activities related to sleep, hygiene, toilet visits and extraction. CONCLUSION: The function of the mini-drain was satisfactory in the majority of cases, but cases with pleural fluid should be avoided. The recurrences were more due to the severe nature of the pulmonary leak rather than to inadequacy of the drain. The side effects mostly occurred in the first patients, so there was a learning curve. The new system should be tried in all patients presenting with an uncomplicated pneumo-thorax allowing ambulatory treatment. Patients with other diseases complicated by pneumothorax could have the new system in order not to be confined to bed. The new system has no place in patients bedridden due to other severe diseases.
