Thoracoscopic surgery for spontaneous pneumothorax

Video-Assisted Thoracic Surgery (VATS) Talc Pleurodesis Versus Pleurectomy for Primary Spontaneous Pneumothorax: A Large Single-Centre Study with No Conversion

BACKGROUND

Primary spontaneous pneumothorax (PSP) is a relatively common clinical entity with high incidence in the young population. Video-Assisted Thoracic Surgery (VATS) bullectomy and chemical or mechanical pleurodesis are two primary modalities of treatment. There has been much debate on the ideal mode of pleurodesis, but the literature on surgical outcomes comparing VATS pleurectomy with talc pleurodesis has been inconclusive.

METHODS

We performed a single-centre 5-year observational retrospective study of 202 patients who underwent VATS bullectomy with talc pleurodesis or parietal pleurectomy.

RESULTS

There were no significant differences in the demographics, pre-operative and intra-operative characteristics in both groups. Recurrence of pneumothorax, chest tube duration and hospital stay were similar in both groups. However, talc pleurodesis had a shorter operative time compared to pleurectomy.

CONCLUSION

Our study demonstrated comparable outcomes between talc pleurodesis and pleurectomy following VATS bullectomy for patients with PSP.

First Episode of Spontaneous Pneumothorax: CT-based Scoring to Select Patients for Early Surgery

BACKGROUND

Although recurrence of primary spontaneous pneumothorax (PSP) is frequent, guidelines do not routinely recommend surgery after first presentation. A CT-based lung dystrophy severity score (DSS) has recently been proposed to predict recurrence following conservative therapy. This study compares the DSS in surgically and conservatively treated patients.

METHODS

This is a retrospective analysis of first episode PSP patients, comparing video-assisted thoracic surgery (VATS; group A) to conservative treatment with or without chest drainage (group B). CT scans were reviewed for blebs or bullae, and patients were assigned DSS values and stratified into risk groups (low and high-grade). Primary end point was ipsilateral or contralateral recurrence.

RESULTS

Fifty-six patients were included, 33 received VATS and 23 conservative treatment. In total, 37.5 % experienced recurrence, with a 5-year estimated recurrence rate of 40.7 % (group A: 13.3 %; group B: 73.9 %; p < 0.001). In group B, detection of any dystrophic lesions resulted in significantly higher 5-year recurrence rates (86.7 vs. 50.0 %; p = 0.03), there was no significant difference in group A (17.7 vs. 7.7 %; p = 0.50). Greater DSS values correlated with higher 5-year recurrence rates in group B (p = 0.02), but not in group A (p = 0.90). Comparing low- and high-grade patients in group B resulted in a significant 5-year recurrence rate of 53.8 versus 100 % (p = 0.023).

CONCLUSIONS

The DSS is useful to indicate VATS after the first episode. For routine application, assigning patients to low- and high-grade groups seems most practical. We recommend CT-evaluation for every PSP patient and early surgery for those with lesions exceeding one bleb. After VATS, the preoperative DSS is not beneficial in predicting recurrence.

A 2-mm Videothoracoscopic Incision for Primary Spontaneous Pneumothorax

This study was designed to evaluate a recently developed 2-mm video-thoracoscope and instruments for primary spontaneous pneumothorax. Between January 1998 and June 1999, 62 consecutive patients were studied. The 2-mm video-thoracoscope was used in 30 patients (group 1), and a conventional video-thoracoscope was used in 32 (group 2). There was no significant difference in operation time, number of staples, or duration of chest tube drainage between the 2 groups. The need for parenteral analgesic (ketoprofen) postoperatively was less in group 1 (56%) than group 2 (72%), but this was not statistically significant. During a mean follow-up of 15 months, there was 1 readmission for recurrent pneumothorax in each group. It was concluded that the 2-mm video-thoracoscope and instruments can be used successfully to manage primary spontaneous pneumothorax with cosmetically excellent results.

Evaluation of Spontaneous Pneumothorax Surgeries: A 16-Year Experience in Japan

Background. Video-assisted thoracoscopic surgery is the surgical procedure of choice for spontaneous pneumothorax due to its noninvasiveness and convenience. A higher recurrence rate with thoracoscopic bullectomy (TB) than that after traditional thoracotomy (TT) led us to adopt thoracoscopic double-loop ligation (TLL) as our standard procedure in 1998. This study compares the effectiveness and safety of these 3 operative procedures. Methods. Patients who underwent their first surgery for spontaneous pneumothorax at our hospital between January 1994 and December 2010 were included. Patients with a history of surgery for spontaneous pneumothorax, those with special clinical conditions such as lymphangioleiomyomatosis, or those with catamenial, traumatic, or iatrogenic pneumothorax were excluded. Results. A total of 777 males (14-91 years old; 814 pneumothorax sides), and 96 females (16-78 years old; 99 pneumothorax sides) were included in the study. TT was performed in 137 patients (143 sides), TB in 106 patients (112 sides), and TLL in 630 patients (658 sides). The postoperative recurrence rates were 3.5%, 16.1%, and 5.3% in the TT, TB, and TLL groups, respectively (p < 0.0001). Mean blood loss and operating time were lowest for TLL. Conclusions. The results suggest that TLL should be the surgical procedure of choice for spontaneous pneumothorax.

Lung resection using transumbilical incision: an animal survival study

INTRODUCTION

Transumbilical single-port surgery is a potentially less invasive approach to many types of abdominal surgeries and offers better cosmetic outcomes than conventional 3-port laparoscopic surgery. It avoids the complication of intercostal neuralgia and may reduce the risk of pulmonary complications after video-assisted thoracic surgery. This study evaluated the feasibility of transumbilical lung wedge resection.

METHODS

Lung resection was performed in 11 beagle dogs weighing 5.9 to 8.5 kg. A 3-cm umbilical incision and one diaphragmatic incision were made, and an endoscopic stapler was used. The diaphragmatic incisions were repaired under video guidance using a V-Loc knotless suturing device (Covidien, Mansfield, Massachusetts). Animals were monitored daily for signs of postoperative infection. White blood cell count, C-reactive protein level, and IL-6 level were measured in all animals. Animals were euthanized 14 days after surgery and underwent necropsy evaluation.

RESULTS

Accurate lung resection was achieved in 10 of 11 animals during a median operative time of 98 minutes (range 60-165). In 1 animal, transumbilical lung resection was not possible and was converted to thoracotomy. All animals survived without major postoperative complications. At necropsy, evidence of uneventful healing of the stapled resection margin and diaphragmatic wound were found. There was no evidence of vital organ injury or intrathoracic infection.

CONCLUSION

A transumbilical approach to thoracic cavity exploration and stapled lung resection is technically feasible. Primary suturing of the diaphragmatic incision is a simple and effective means of diaphragmatic wound closure. This may be an alternative to video-assisted thoracic surgery for the management of simple thoracic disease.

A single institution experience using the LigaSure vessel sealing system in video-assisted thoracoscopic surgery for primary spontaneous pneumothorax

This study sought to report our 6-year experience with the LigaSure vessel sealing system (LVSS) in video-assisted thoracoscopic surgery (VATS) for primary spontaneous pneumothorax. A series of 180 consecutive patients with primary spontaneous pneumothorax were operated on in our institution from May 2005 to December 2010. Intraoperatively, large lesions (bullae or blebs) with a diameter more than 2 cm were resected by staplers, and the residual lesions were treated by LVSS. LVSS was also used to ablate the apical area when no lesions were found. Conventional apical pleural abrasion was done in all cases. All patients were successfully treated using VATS with minimal perioperative bleeding. The mean operating time was 76 minutes (range, 43-160 minutes) for single-side procedures and 169 minutes (range, 135-195 minutes) for bilateral procedures, the mean number of applied staples was 1.93 per patient (range, 0-8 days), the duration of drainage was 3.8 days (range, 2-15 days), and the duration of hospital stay was 5.8 days (range, 3-16 days). Postoperative complications included persistent air leak (> 5 days) in 11 cases (6.1%) and residual pneumothorax in 6 (3.3%). None required reoperation. The mean duration of follow-up was 57 months (range, 24-105 months). Recurrence was seen in three cases (1.7%), and all underwent another operation thereafter. None of the lesions in the relapse cases received ablation with LVSS in the first operation. LVSS can optimize VATS for primary spontaneous pneumothorax and reduces the use of single-use staples. The method is safe, easy to use, and cost-effective and produces satisfactory results.

Video-assisted thoracic surgery complications

Video-assisted thoracic surgery (VATS) is a miniinvasive technique commonly applied worldwide. Indications for VATS are very broad and include the diagnosis of mediastinal, lung and pleural diseases, as well as large resection procedures such as pneumonectomy. The most frequent complication is prolonged postoperative air leak. The other significant complications are bleeding, infections, postoperative pain and recurrence at the port site. Different complications of VATS procedures can occur with variable frequency in various diseases. Despite the large number of their types, such complications are rare and can be avoided through the proper selection of patients and an appropriate surgical technique.

Feasibility of transumbilical lung wedge resection in a canine model

BACKGROUND

Chronic wound discomfort and intercostal neuralgia are well-known postoperative complications of video-assisted thoracoscopic surgery (VATS). To explore the possibility of a surgical platform that would cause less postoperative discomfort and avoid these complications, this study evaluated the feasibility of transumbilical lung wedge resection in a canine model.

MATERIALS AND METHODS

Twelve dogs (4 in the nonsurvival group and 8 in the survival group) were used in this study. Transumbilical thoracoscopy was performed using a homemade metallic tube via umbilical and diaphragmatic incisions with the animal in a supine position. After thoracic exploration, wedge resection was performed on the lung using an endoscopic stapling device placed through the transumbilical and transdiaphragmatic incisions under direct bronchoscopic guidance. The animals were sacrificed 30 minutes after the procedure (nonsurvival group) or 14 days postsurgery (survival group) for necropsy and histological evaluations.

RESULTS

Eleven preplanned lung wedge resections were completed in a median time of 101 minutes (range, 65-175 minutes) with one exception due to inadequate stapling in the early phase of the experiment. There was one death directly related to postoperative massive airleaks and sepsis in the survival group. The other 7 animals had an uneventful postoperative period. Necropsies at 2 weeks after surgery confirmed successful lung resections and revealed no evidence of vital organ injury. Two animals exhibited complete healing of the diaphragmatic incision. Liver herniation was identified in 1 of 5 animals with partial wound healing.

CONCLUSIONS

This preliminary animal study demonstrates that large lung wedge resection can be performed with mechanical staplers via a single transumbilical incision. Future studies will investigate the cardiopulmonary and immunologic effects of transumbilical VATS compared with conventional VATS.

Review: Diagnosis and treatment of primary spontaneous pneumothorax

Primary spontaneous pneumothorax (PSP) commonly occurs in tall, thin, adolescent men. Though the pathogenesis of PSP has been gradually uncovered, there is still a lack of consensus in the diagnostic approach and treatment strategies for this disorder. Herein, the literature is reviewed concerning mechanisms and personal clinical experience with PSP. The chest computed tomography (CT) has been more commonly used than before to help understand the pathogenesis of PSP and plan further management strategies. The development of video-assisted thoracoscopic surgery (VATS) has changed the profiles of management strategies of PSP due to its minimal invasiveness and high effectiveness for patients with these diseases.

Bullae ablation in primary spontaneous pneumothorax

BACKGROUND

The benefit of bullae ablation for the management of primary spontaneous pneumothorax (PSP) has been established. However, various modalities for bullae ablation have been reported from different centers.

OBJECTIVE

The present study aimed to assess whether endoloop ligation of bullae was as effective as staple bullectomy for preventing the recurrence of pneumothorax.

METHODS

Between January 1993 and December 2003, 226 patients (203 men and 23 women) with PSP were recorded and retrospectively reviewed. One hundred thirty (57.5%) patients were treated with endoloop ligation of bullae and the other 96 (42.5%) were treated with staple bullectomy. Mechanical abrasion was performed in all patients after bullae ablation.

RESULTS

The recurrence rate of pneumothorax was 6.2% (8 patients) in the endoloop ligation group and 17.7% (17 patients) in the staple bullectomy group (p = 0.006). The postoperative complication rate was 14.6 and 20.8% in the endoloop ligation and staple bullectomy groups, respectively (p = 0.221). The long-term chest discomfort rate after endoloop ligation and staple bullectomy was 14.6 and 13.5%, respectively (p = 0.819)

CONCLUSIONS

Endoloop ligation of bullae is as effective as mechanical staple bullectomy for the management of bullae in primary spontaneous pneumothorax.

Thoracoscopic bleb resection using two-lung ventilation anesthesia with low tidal volume for primary spontaneous pneumothorax

BACKGROUND

We performed thoracoscopic surgery for pneumothorax using two-lung ventilation with low tidal volume and evaluated the feasibility and safety of this procedure.

METHODS

Forty-six patients (mean age, 23.6 +/- 10.47 years) each with a primary spontaneous pneumothorax underwent wedge resection with chemical and mechanical pleurodesis. Two-lung ventilation anesthesia was performed with a single-lumen endotracheal tube, and the tidal volume was reduced to 4 mL/kg; the respiratory rate was increased to 24 cycles/min. Airway pressure, end-tidal CO(2), and the results of blood gas analysis were obtained right after endotracheal intubation and during the operation, and were compared.

RESULTS

The tidal volume was 496.2 +/- 94.33 mL at anesthesia induction, which decreased to 243.9 +/- 34.43 mL during the two-lung ventilation. In 5 patients, the tidal volume was additionally decreased by 32.5 +/- 12.58 mL (p = 0.014) to obtain an optimal working field. The differences between the airway pressure, pH, partial pressure of carbon dioxide, and partial pressure of oxygen were significant between the two measurement times. However, all of the values of the arterial blood gas analysis were within normal range. The oxygen saturation (99.9% +/- 0.69% versus 99.8 +/- 0.72%; p = 0.160) and end-tidal CO(2) (33.2 +/- 3.74 mm Hg versus 34.1 +/- 4.19 mm Hg; p = 0.157) were not significantly different. The time from intubation before the incision was 17.1 +/- 4.18 minutes, the operation time was 31.9 +/- 14.48 minutes, and the total anesthesia time was 65.8 +/- 15.02 minutes.

CONCLUSIONS

Thoracoscopic surgery for primary spontaneous pneumothorax using two-lung ventilation with low tidal volume was technically feasible.

Video-assisted thoracoscopic surgery (VATS) for bilateral primary spontaneous pneumothorax

OBJECTIVE

To review our experience of the treatment of bilateral primary spontaneous pneumothorax (PSP) by video-assisted thoracoscopic surgery (VATS).

MATERIALS AND METHODS

Retrospective chart review was followed by an on-clinic or telephone interview. Patients were cared for by one thoracic surgeon in four medical centers or community hospitals in Northern and Central Taiwan. Thirteen patients with bilateral PSP underwent bilateral VATS simultaneously or sequentially from July 1994 to December 2005.

RESULTS

Twelve males and one female, with age ranging from 15 to 36 years (mean 23.1 years), were treated with VATS for bilateral PSP, under the indications of bilateral pneumothoracis simultaneously (n=4) or sequentially (n=9). The interval between the first and second contra-lateral VATS procedure for non-simultaneous PSP patients ranged from 7 d to 6 years. Eleven of 13 patients (84.6%) had prominent pulmonary bullae/blebs, and underwent bullae resection with mechanical or chemical pleurodesis. The mean operative time was (45.6+/-18.3) min (range 25 approximately 96 min) and (120.6+/-28.7) min (range 84 approximately 166 min) respectively for the non-simultaneous (second VATS for the recurrence of contralateral side after first VATS) and simultaneous (bilateral VATS in one operation) procedures. There was no postoperative mortality. However, prolonged air leakage (>7 d) occurred in one patient (7.7%) who recovered after conservative treatment. The mean duration of chest tube drainage was 3.1 d and the median follow up period was 3.4 years.

CONCLUSIONS

VATS is a safe and effective procedure in the treatment of bilateral PSP. Bilateral VATS is only recommended for patients with simultaneously bilateral PSP, because the incidence of recurrence, even with visible bullae, was not so high in my group and in some previous literature. Bilateral VATS in a supine position should only be used in selective cases, because of possible pleural adhesion or hidden bullae on the posterior side.

Video assisted thoracic surgery in the management of spontaneous pneumothorax: the current status

Over the past decade, video assisted thoracic surgery (VATS) has changed the way spontaneous pneumothorax (SP) is managed. Benefits of VATS include less postoperative pain, shorter hospital stay, and attenuated postoperative inflammatory response are evident compared with open thoracic procedures. Furthermore, the increasing acceptance by patients and referring physicians is testament to its success. Recent studies and the authors decade of experience in management of SP by VATS show that it is quick, safe, and effective, with recurrence rates generally comparable to open procedures, with some exceptions. However, selecting the correct procedure and patient, as well as knowing the limitations of the surgeons and techniques are paramount for success. Even to this day, there are considerable variations in the treatment of SP and large scale controlled studies are needed to better define timing of surgery and the role of the different procedures in the treatment and prevention of SP.

[Effectiveness and complications of video-assisted surgery for primary spontaneous pneumothorax]

OBJECTIVE

To assess the effectiveness and describe the complications of video-assisted thoracoscopic surgery (VATS) for the treatment of primary spontaneous pneumothorax.

PATIENTS AND METHODS

Between May 1997 and September 2003, our department scheduled 147 VATS procedures for spontaneous pneumothorax in 127 patients (102 men [80.5%]). The mean (SD) age for the series was 28.3 (11.6) years. Bullae and blebs were resected by endostapler and vigorous pleural abrasion was carried out. Vanderschueren staging was as follows: stage I, 10 (6.8%); stage II, 22 (15%); stage III, 71 (48.3%); and stage IV, 44 (29.9%). The procedure was indicated for the following reasons: third episode, 56 (38.1%); persistent air leak, 47 (32%); elective, 16 (10.9%); simultaneous bilateral pneumothorax, 28 (19%). VATS was performed on the right side only in 85 patients (57.8%), on the left in 62 (42.2%), and on both sides in 16 (11.6%).

RESULTS

A total of 137 of the 147 VATS procedures scheduled (93.2%) were performed, and there were no deaths. The rate of conversion to thoracotomy was 6.8%, and the overall rate of complications was 13.7%. Postoperative complications were due to bleeding in 5 cases (3.6%), air leak (>5 days) in 10 (7.2%), wound infection in 2 (1.4%), residual pneumothorax in 4 (2.9%), need to insert a new pleural drain in 3 (2.1%), and pleural empyema in 1 (0.7%). Two patients took oral analgesics for more than 30 days after the procedure. Pneumothorax recurred during follow-up in 7 patients (5.1%). No significant correlation was found between recurrence of pneumothorax after VATS and Vandeschueren stage, age, bilaterality of the procedure, indication, or days of postoperative drainage (P>.05).

CONCLUSIONS

VATS for resection of pleural lesions plus pleural abrasion is an efficacious and simple treatment for primary spontaneous pneumothorax regardless of intraoperative findings.

Video-assisted thoracic surgery--the past, present status and the future

Video-assisted thoracic surgery (VATS) has developed very rapidly in these two decades, and has replaced conventional open thoracotomy as a standard procedure for some simple thoracic operations as well as an option or a complementary procedure for some other more complex operations. In this paper we will review its development history, the present status and the future perspectives.

Video-assisted thoracoscopic surgery (VATS) pleurodesis for pneumothorax

Spontaneous pneumothorax is a common condition that impacts significantly on healthcare expenditure. Its optimal management, however, remains a subject of considerable controversy. The proven safety and efficacy of minimal access video-assisted thoracic surgery (VATS) has changed the way we manage this condition. We present VATS pleurodesis utilizing the endoscopic stapling technique for the management of spontaneous pneumothorax.

Traitement actuel du pneumothorax primaire et secondaire

INTRODUCTION

The treatment of a primary or secondary spontaneous pneumothorax remains controversial and many therapeutic options exist. In the event of a first episode of pneumothorax, should the patient be treated by observation, aspiration or thoracic drainage? For patients undergoing a thoracoscopic intervention for a spontaneous pneumothorax which is the best technique to treat the lung and parietal pleura? What are the results of thoracoscopy compared to thoracotomy and are the costs comparable?

PERSPECTIVES

The optimal treatment for a first episode of pneumothorax remains to be determined. As there are only a limited number of patients in the published randomised controlled studies only grade B or C recommendations can be given. This is also true for the treatment of the lung and parietal pleura during a thoracoscopic intervention. Most authors advise that an apical pleurectomy is performed. With regard to results and cost of thoracoscopy compared to thoracotomy, conflicting results have been published and definite conclusions cannot be drawn.

CONCLUSION

As large randomised prospective studies are not available regarding the treatment of pneumothorax only grade B or C recommendations can be given.

Video-assisted thoracic surgical treatment of initial spontaneous pneumothorax in young patients

BACKGROUND

The treatment of primary spontaneous pneumothorax in young adults has been controversial. Conventional treatment consisting of chest tube thoracostomy may be associated with morbidity at the time of tube insertion, prolonged hospitalization, and interval operation in many patients. As spontaneous pneumothorax in young adults is usually associated with apical blebs, we hypothesized that video-assisted thoracic surgical (VATS) resection of the blebs at the time of the first pneumothorax may be an effective treatment associated with low morbidity and short hospital stays.

METHODS

From July 1992 to February 2001, 156 young adults were treated for spontaneous pneumothorax. Within 12 hours of presentation to the emergency department patients underwent semielective VATS with bleb resection and pleuradesis. During follow-up patients were observed for recurrent pneumothorax.

RESULTS

There were 69 men (44%) and 87 women (56%). The median age was 19 years old (range 14 to 38 years old). Patients were predominantly tall and thin. Patients were mildly symptomatic at the time of presentation. Apical blebs were seen in all patients and the presence of blebs was confirmed in the pathologic specimen. In 23 patients bleeding was associated with bleb rupture. There were no postoperative air leaks. The mean hospital stay was 2.4 +/- 0.5 days. Follow-up ranged from 2 to 96 months (median 62 months). There were no recurrences on the index side.

CONCLUSIONS

VATS resection of apical blebs is associated with low morbidity and short hospitalization and provides an attractive alternative to the conventional treatment of initial tube thoracostomy and possible interval repeat thoracostomy or operation. VATS may be an effective first line treatment for spontaneous pneumothorax in young adults. Due to the pathophysiology of this disease, patients should be closely followed for the occurrence of pneumothorax on the contralateral side.

Implications of removing a normal appendix

BACKGROUND

The diagnosis of acute appendicitis remains difficult and therefore 15-30% of the removed appendices appear to be normal. The aim of this study was to investigate morbidity, mortality and costs of removing a normal appendix in patients with suspected appendicitis.

PATIENTS AND METHODS

Retrospective study of patients who underwent a negative appendectomy for suspected appendicitis in the period 1991-1999 with a median follow-up of 4.4 years. Patients who underwent an elective appendectomy or appendectomy for other reasons were excluded.

RESULTS

In 285 patients (70% women, 30% men) a normal appendix was removed. In 192 (67%) patients a muscle-splitting incision was performed, in 6 (2%) a median laparotomy, and in 51 (18%) the normal appendix was removed by laparoscopy. In 36 patients (13%) a diagnostic laparoscopy was converted to a muscle-splitting incision. Complications occurred in 16 (6%) patients, in 5 (2%) a re-operation was needed. The mean hospital stay was 4.4 (SE 2.8) days, in case of complications 7.4 (SE 4.2) days. The mean extra hospital costs of a negative appendectomy were EUR 2712.

CONCLUSION

The removal of a normal appendix has considerable complications and costs. In an attempt to prevent these costs, extra diagnostic tools should be considered. Expensive diagnostic tools such as diagnostic laparoscopy should be used selectively in order not to further increase costs.

Thoracoscopic management of primary spontaneous pneumothorax

BACKGROUND

Video-assisted thoracoscopic surgery (VATS) is the preferred option for the surgical management of primary spontaneous pneumothorax (PSP).

AIMS

To evaluate the role of thoracoscopic blebectomy with and without chemical pleurodesis.

METHODS

A retrospective study was performed on 113 consecutive cases carried out in one unit. RESULTS; One hundred and thirteen VATS procedures were performed on 108 patients. The mean age was 23 years (range 14-45). The male to female ratio was 82:26. Recurrent pneumothorax was the indication for surgery in 80%. Conversion to an open procedure was required in 10 cases (9%), most commonly due to severe adhesions. Successful endoscopic blebectomy was performed in 98 cases (87%), 48 of which had an additional chemical pleurodesis. Follow-up is currently to a mean of 28 months. Recurrence has occurred in eight cases, including only three in the group managed with additional chemical pleurodesis (6.25%).

CONCLUSION

VATS with blebectomy and chemical pleurodesis is a safe and effective procedure in the management of PSP.

Thoracoscopy in the management of pneumothorax

Spontaneous pneumothorax is a common condition that impacts significantly on healthcare expenditure. However, optimal management of spontaneous pneumothorax remains a subject of considerable controversy. A thoracic surgeon's perspective on the use of thoracoscopy and video-assisted thoracic surgery with a focus on surgical techniques in the current management of this condition is presented.
