Should surgical pleurectomy for spontaneous pneumothorax be always thoracoscopic?

Fifty-seven patients were studied over a period of three years to analyse the efficacy of surgical pleurectomy for spontaneous pneumothorax. Thirty-one and 26 patients underwent open and video-assisted thoracoscopic surgery (VATS) pleurectomy, respectively. VATS was the main modality used for primary spontaneous pneumothorax (PSP) (21 vs. 8). However, secondary spontaneous pneumothorax (SSP) was mainly managed with open pleurectomy (23 vs. 5). The median operating time was significantly longer in open group (72.4 vs. 55 min; P=0.005). The amount of analgesia required in the first five days was significantly more in open group (108 mg vs. 46.9 mg; P=0.02). Chest drainage was significantly more in open group (1027.1 ml vs. 652.8 ml; P=0.04). However, chest drain duration and hospital stay had no significant difference. VATS emerged as a cost-effective modality (1770 pounds vs. 3226 pounds). The ability to return to work was significantly earlier in VATS group in PSP patients (6 weeks vs. 10 weeks; P=0.007). There were 3 (5.27%) recurrences in VATS group for patients with SSP. This experience suggests that VATS pleurectomy is an appropriate modality for PSP. However, open pleurectomy is a viable alternative to treat SSP.     

Four-year experience with pleural abrasion using a rotating brush during video-assisted thoracoscopy

BACKGROUND: Due to the high recurrence rate in primary spontaneous pneumothorax (PSP), surgical therapy is currently a well-accepted method of treating this condition. There is no general agreement about the best time for surgical intervention (i.e., after the first or second episode) or the optimal surgical approach,--i.e., tube thoracocenteses, thoracotomy, or video-assisted thoracoscopy (VATS) with or without pleurectomy or pleurodesis. The aim of this study was to verify the efficacy of VATS and mechanical brush pleurodesis using a rotating electrical brush system. METHODS: We treated 47 patients with PSP between June 1993 and June 1997. Follow-up ranged from 20 to 56 months. There were 38 male and nine female patients with a mean age of 26 years. Emergency thoracocenteses due to tension pneumothorax became necessary in three patients. All patients were treated by VATS and mechanical brush pleurodesis. Wedge resection was done if bullae or blebs were present (68.1%). RESULTS: Operating time was 20-60 min (mean, 35). There were no intraoperative complications and no conversions to conventional surgery. In the first few postoperative days, postoperative pain was controlled with nonsteroidal antirheumatic drugs and additional morphines. Drainage time was 3-7 days (mean, 4). Hospitalization time was 4-8 days (mean, 5). The recurrence rate was 2.1% (one patient). No postoperative bleeding or wound infection occurred in any of our patients. CONCLUSIONS: VATS combined with mechanical brush pleurodesis using the electrical brush system is a highly effective and safe treatment for patients with recurrent primary spontaneous pneumothorax.     

Benefits of early aggressive management of empyema thoracis

BACKGROUND: The end-target of the management of thoracic empyema is to obtain early rehabilitation by re-expansion of the trapped lung resulting from intrapleural infected material. Our aim was to shorten the hospitalization time and to prevent a possible thoracotomy by using video-assisted thoracoscopy initially. METHODS: Seventy patients with parapneumonic empyema were prospectively studied between January 1997 and June 2004. The patients were randomly divided into two groups. In group I (n = 35 patients), a chest tube was inserted into the patients after pleural content was evacuated and fibrins were debrided using video-assisted thoracoscopy. In group II (n = 35 patients), tube thoracostomy was carried out without using a video-assisted thoracoscope. Both groups were compared in terms of hospitalization time, open surgery for decortication and complications. RESULTS: There was no statistically significant difference between the groups from the point of view of age and sex (P > 0.05). In group I, 17.1% of the patients underwent open decortication, whereas in group II, 37.1% of the patients underwent the same procedure (P < 0.05). Whereas average hospital stay in group I was 8.3 days (range, 7-11 days), it was 12.8 days in group II (range, 10-18 days; P < 0.05). There was one bronchopleural fistula in group I, and there was one bronchopleural fistula and one death in group II. CONCLUSION: Video-assisted thoracoscopic evacuation and chest tube insertion in situ is a new therapeutic approach for pleural empyema that shortens hospital stay and reduces the necessity of open decortication.     

Optimal timing of video-assisted thoracoscopic surgery for primary spontaneous pneumothorax in children

Purpose

There is no consensus in the pediatric surgical community about when to recommend video-assisted thoracoscopic surgery (VATS) for patients with primary spontaneous pneumothorax (PSP). We aimed to identify factors that predict the likelihood of requiring VATS, and to compare recurrence rates and healthcare utilization among different management approaches to PSP.

Stage-adapted therapy of pleural empyema. Results during 1992-1998

Despite the decreasing number of patients suffering tuberculosis and the use of modern broad spectrum antibiotics the pleural empyema did not lose its relevance. The main reasons are increasing numbers of patients with drug and alcohol abuse or immunodeficiency of different causes. We retrospectively analysed the data of 73 patients treated of pleural empyema between 1992 and 1998. Considering the known stages of pleural empyema we present the corresponding therapeutic results. All patients classified as stage I were treated with a chest drain and cure was achieved in all of them (100%). The treatment for patients classified as stage II was different: 5 out of 32 were treated with a continuous irrigation and suction chest drain system. 18 patients first underwent thoracoscopy and were afterwards treated with a continuous irrigation and suction system. Another 9 patients primarily underwent an early open decortication. In 40% the treatment with the suction and irrigation system was successful. Using video-assisted thoracoscopy (VATS) cure was achieved in 94.4%, with open decortication in 100%. The preferred treatment of patients classified as stage III is the open decortication. After the first operation 80% (30 patients) were cured. 6 patients needed thoracoplastic procedures after the first intervention. No patient was discharged neither with a permanent chest drain nor a permanent thoracic window. With the results a cause dependent analysis of morbidity and mortality was done. The overall morbidity rate was 27.9% and the overall mortality 5.4%. The treatment of pleural empyema still remains to be problematic. Corresponding to our results pleural empyema classified as stage I is best treated with a simple chest tube. The video-assisted thoracoscopy (VATS) lacks of complications and is a very efficient method in treating stage II. The method of choice in stage III is the open decortication which in the case of a chronic and recurrent or persistent infection should be followed by a thoracoplastic procedure.     

Management of Primary Spontaneous Pneumothorax in Children: A Single Institution Protocol Analysis

BackgroundThe Midwest Pediatric Surgery Consortium (MWPSC) suggested a simple aspiration of primary spontaneous pneumothorax (PSP) protocol, failing which, Video-Assisted Thoracoscopic Surgery (VATS) should be considered. We describe our outcomes using this suggested protocol.MethodsA single institution retrospective analysis was conducted on patients between 12 and 18 years who were diagnosed with PSP from 2016 to 2021. Initial management involved aspiration alone with a ≤12 F percutaneous thoracostomy tube followed by clamping of the tube and chest radiograph at 6 h. Success was defined as ≤2 cm distance between chest wall and lung at the apex and no air leak when the clamp was released. VATS followed if aspiration failed.ResultsFifty-nine patients were included. Median age was 16.8 years (IQR 15.9, 17.3). Aspiration was successful in 33% (20), while 66% (39) required VATS. The median LOS with successful aspiration was 20.4 h (IQR 16.8, 34.8), while median LOS after VATS was 3.1 days (IQR 2.6, 4). In comparison, in the MWPSC study, the mean LOS for those managed with a chest tube after failed aspiration was 6.0 days (±5.5). Recurrence after successful aspiration was 45% (n = 9), while recurrence after VATS was 25% (n = 10). Median time to recurrence after successful aspiration was sooner than that of the VATS group [16.6 days (IQR 5.4, 19.2) vs. 389.5 days (IQR 94.1, 907.0) p = 0.01].ConclusionSimple aspiration is safe and effective initial management for children with PSP, although most will require VATS. However, early VATS reduces length of stay and morbidity.Level of evidenceIV. Retrospective study.     

Lung wedge resection improves outcome in stage I primary spontaneous pneumothorax

BACKGROUND: To evaluate the role of apical lung wedge resection in patients with recurrent primary spontaneous pneumothorax with no endoscopic abnormalities at surgery as compared with simple apical pleurectomy. METHODS: We performed a retrospective analysis on 126 consecutive video-assisted thoracoscopic surgery (VATS) procedures in 113 patients treated for stage I recurrent PSP between January 1994 and December 2001. Two surgical strategies were applied: simple apical pleurectomy (57 procedures, 45.2%: group A) and apical pleurectomy together with an apical lung wedge resection (69 procedures, 54.8%: group B). RESULTS: Mean duration of chest tubes was 1.4 days (range, 1 to 7), mean hospital stay was 2.4 days. Three patients (2.4%) required redo VATS, 2 in group A (3.5%) for persistent air leak and 1 (1.4%) in group B for apical hematothorax. Mean follow-up was 38.7 months. Overall recurrence rate was 3.2%. Four patients in group A (7%) experienced recurrent ipsilateral pneumothoraces 4 to 73 weeks (mean, 30.2) after surgery. No recurrences were observed in group B (p = 0.009). CONCLUSIONS: In this selected group of patients without endoscopical abnormalities, VATS offers low recurrence rates. However, these data suggest that apical pleurectomy should be accompanied by apical lung wedge resection even for this favorable category of patients.     

Video-assisted thoracic surgery for primary spontaneous pneumothorax in children: is there an optimal technique?

Objective

Video-assisted thoracic surgery (VATS) for treatment of spontaneous pneumothorax refractory to nonoperative management was first reported in children by Rodgers in 1986 (Ann Surg. 1986; 204:677-680). Small series have shown success with apical blebectomy, mechanical or chemical (talc) pleurodesis, or combination techniques. We report the largest pediatric series of VATS for primary spontaneous pneumothorax (PSP) to date, to assess outcomes and compare techniques.

Methods

Retrospective review of all children undergoing VATS for PSP between 1999 and 2007 at 2 university-affiliated hospitals by the same group of surgeons. Mann-Whitney U tests and χ² used (P < .05 = significant).

Results

Thirty-two patients underwent 41 VATS procedures (32 initial-30 unilateral, 2 bilateral; 9 subsequent-7 contralateral, 2 ipsilateral recurrences). Mean age at presentation was 16.5 years (range, 13-20 years). Blebs were identified at the time of VATS in 95% of patients, but in 12.5%, they were on lower lobes. Mean duration of postoperative air leak was 2.7 days, postoperative hospital length of stay was 5.0 days, and postoperative chest tube duration was 5.1 days; 2 patients required Heimlich valves, which were managed at home. Five different surgical techniques were used as follows: blebectomy plus mechanical pleurodesis had the shortest length of stay (4.3 days) and need for chest tube drainage (4.1 days) but had a higher recurrence risk (6% major, 16% minor) than blebectomy plus chemical pleurodesis. The risk of requiring an additional VATS procedure (ipsilateral or contralateral) was 28%. Mean follow-up was 46 months.

Conclusions

Blebectomy plus either mechanical or chemical pleurodesis were both associated with acceptable outcomes. Blebectomy plus chemical pleurodesis appears to have less risk of ipsilateral recurrence but longer postoperative stay and chest tube drainage.     

Evaluation of video-assisted thoracoscopic surgery in the diagnosis of diaphragmatic injuries

: Injury to the diaphragm from penetrating or blunt thoracoabdominal trauma is notoriously difficult to diagnose. Chest radiography, computed tomography scan, contrast studies, diagnostic peritoneal lavage, and laparoscopy are inadequate; thus, celiotomy is commonly performed in patients with suspected diaphragmatic injury. We compared the diagnostic accuracy of video-assisted thoracoscopic surgery (VATS) with that of exploratory celiotomy in the evaluation of diaphragmatic and thoracoabdominal injury. : Hemodynamically stable patients admitted to a level I trauma center with blunt or penetrating injury to the lower chest or abdomen underwent VATS and subsequent celiotomy under the same general anesthetic. Intraoperative thoracoscopic findings were blinded to the abdominal surgeons. : Twenty-six patients were enrolled in the study over a 12-month period. Diaphragmatic injuries were identified in 8 patients (31%). Videothoracoscopy identified all eight injuries in these patients. Six of the 8 patients (75%) with diaphragmatic injuries sustained associated injury to intrathoracic or intra-abdominal organs. There was no mortality and no procedure-related morbidity. There were no missed injuries in patients who underwent VATS. : Video-assisted thoracoscopy is a safe, expeditious, and accurate method of evaluating the diaphragm in injured patients, and is comparable in diagnostic accuracy to exploratory celiotomy.     

Video-assisted thoracic surgery as a primary therapy for primary spontaneous pneumothorax

Background: Because blebs are confirmed in most of the patients undergoing thoracotomy, identification of blebs by high-resolution computed tomography (HRCT) can be proposed as a surgical indication in primary spontaneous pneumothorax (PSP). If an apical bleb is identified, we treat the patient by video-assisted thoracic surgery (VATS). Methods: From May 1995 to September 1997, 61 patients (21.9 ± 4.6 years) were seen for initial episodes of PSP. Only seven showed bullae on simple chest radiography. However, by HRCT, 48 had sizable blebs (>5 mm), and 45 were treated surgically by VATS. Results: The mean duration of chest tube use after surgery was 3.2 ± 1.9 days, and the mean hospital stay was 4.5 ± 1.9 days. Only one recurrence developed 5 weeks after VATS. Conclusions: Our protocol is effective in controlling an initial episode of PSP. It shortens the observation time before definitive surgical treatment, shortens the hospital stay, and decreases the likelihood of recurrence. Received: 25 June 1997/Accepted 18 February 1998     

Role of early thoracoscopy for management of penetrating wounds of the chest

Most nonlife-threatening penetrating wounds of the chest (PWC) are treated with a chest tube alone. This may be inadequate because missed injuries, retained hemothorax, or foreign material may be difficult to address later. Early thoracoscopy should improve outcome. We conducted a retrospective review of 88 stable patients with PWC initially treated with a chest tube and had retained a hemothorax beyond 48 hours. Twenty-seven underwent an early video-assisted thoracoscopy (VATS). Fifty-five were observed, chest tubes were manipulated, or an additional one placed. The outcome was compared with the National Trauma Data Bank and controlled for Injury Severity Score. Early VATS reduced length of stay (4.3 vs 9.4 days), days in the intensive care unit (1.3 vs 3.2), and open thoracotomy (0 vs 7). A chest tube undertreats a nonlife-threatening PWC correctable by timely VATs.     

Video-assisted thoracic surgery in the treatment of spontaneous pneumothorax

BACKGROUND: The aim of this study was to evaluate the surgical indications and the results of a series of 107 patients treated by video-assisted thoracic surgery for spontaneous pneumothorax with a minimum follow-up of 12 months. METHODS: From January 1991 to December 1997, 107 patients (86 male and 21 female patients) mean age 28 years (range 14-78), underwent VATS for treatment of spontaneous pneumothorax. RESULTS: Seventy-five patients had primary spontaneous pneumothorax (PSP) and thirty-two patients had secondary spontaneous pneumothorax (SSP). Bullous area was not seen in 26 patients with PSP. Ninety-nine patients were treated with wedge stapled resection of the bullous area or of the apex (when no bullous area was seen) and some form of pleurodesis, whereas 8 patients with PSP were treated only with pleurodesis. Among these 8 patients, two presented recurrence. Two patients with PSP and 8 patients with SSP were treated by apical pleurectomy: no one developed recurrence. The other 97 were treated with electrocoagulation of the parietal pleura. Conversion to a thoracotomy was necessary in 4 patients (12.5%) because of massive pleural adhesions. There were no postoperative deaths. A complication developed in 3 patients (4%) with PSP and in 5 patients (17.8%) with SSP, whose procedure was ended by VATS. The duration of systematic postoperative drainage was 3.8 +/- 0.9 (range 3-15 days) for the group of patients with PSP and 6 +/- 2.1 (range 4-23 days) for the group of patients with SSP. The duration of the hospital stay was 5.6 +/- 1.4 (range 4-15) and 8.4 +/- 2.3 (range 6-18) in patients with PSP and SSP respectively. Follow-up analysis revealed 2 (2.66%) ipsilateral recurrent pneumothorax in 75 patients treated for PSP. Among 26 patients with SSP, whose procedure was completed by VATS, 2 recurrences (7.7%) were observed. CONCLUSIONS: Surgical treatment by VATS is a valid alternative to open thoracotomy in patients with PSP and will be the treatment of choice because, with increased experience of surgeons, it will yield the same results as standard operative therapy but with the advantages of the minimally invasive operation. The usefulness of VATS in patients with SSP remains to be defined.

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.     

Less invasive needle thoracoscopic laser ablation of small bullae for primary spontaneous pneumothorax.

OBJECTIVE: The purpose of this study was to establish a new surgical technique of thoracoscopic laser ablation for the patients of primary spontaneous pneumothorax (PSP) with small bullae, by using endoscopic equipment with a 2-mm diameter. METHOD: According to the size of a bulla identified by high-resolution computed tomography (HRCT), we have a protocol to determine an indication; the conventional video-assisted thoracic surgery (VATS) procedure by both stapler bullectomy and laser ablation to visceral pleura surrounding the bulla (bullae size: greater than 2 cm), or a new VATS procedure using needle shaped thoracoscopy and endoscopic equipment with a 2-mm diameter (needle VATS) by laser bulla ablation alone (bullae size: less than 2 cm). RESULTS: The conventional VATS was performed in 54 patients and needle VATS in 60 patients. In the needle VATS group, operation time was shorter than that of the VATS group (39+/-17 min vs. 56+/-22 min). Use of non-steroidal anti-inflammatory drugs for postoperative wound pain could be reduced in the needle VATS group (3% vs. 56%). There were no complications in the needle VATS group, but three complications (5.6%) in the VATS group, including prolonged air leakage (>4 days) in two and refractory intercostal pain in one. The rate of recurrence after the operation was similar in both groups (3.7% vs. 3.3%). The needle VATS allowed wound healing without a scar and reduced the patient's cosmetic problems. CONCLUSION: The needle VATS procedure for patients with a bulla size less than 2-cm diameter was as useful as the conventional VATS procedure.     

A randomized, controlled trial comparing thoracoscopy and limited thoracotomy for lung biopsy in interstitial lung disease

BACKGROUND: Lung biopsies are frequently needed to diagnose diffuse interstitial lung diseases. A prospective randomized, controlled trial comparing limited thoracotomy (open lung biopsy) and thoracoscopy for lung biopsy was done. METHODS: Ambulatory patients with a clinical diagnosis of diffuse interstitial lung disease were randomized to thoracoscopy or limited thoracotomy. Data on postoperative pain, narcotic requirements, operating room time, adequacy of biopsy, duration of chest tube drainage, length of hospital stay, spirometry, and complications were collected. RESULTS: A total of 42 randomized patients underwent lung biopsy (thoracoscopy 20, thoracotomy 22). The two study groups were comparable with respect to age, gender, corticosteroid use, and preoperative spirometry. Visual analog scale pain scores were nearly identical in the two groups (p = 0.397). Total morphine dose was 50.8 +/- 27.3 mg in the thoracoscopy group and 52.5 +/- 25.6 mg in the thoracotomy group (p = 0.86). Spirometry (FEV1) values in the two groups were not significantly different on postoperative days 1, 2, 14, and 28 (p = 0.665). Duration of operation was similar in both groups (thoracoscopy 40 +/- 30 minutes, thoracotomy 37 +/- 15 minutes; p = 0.67). The thoracoscopy and thoracotomy groups had equivalent duration of chest tube drainage (thoracoscopy 38 +/- 28 hours, thoracotomy 31 +/- 26 hours; p = 0.47) and length of hospital stay (thoracoscopy 77 +/- 82 hours, thoracotomy 69 +/- 55 hours; p = 0.72). Definitive pathologic diagnoses were made in all patients. CONCLUSIONS: There is no clinical or statistical difference in outcomes for thoracoscopic and thoracotomy approaches. Both thoracoscopy and thoracotomy are acceptable procedures for diagnostic lung biopsy in diffuse interstitial lung disease.     

Is video-assisted thoracic surgery indicated in the first episode primary spontaneous pneumothorax?

Primary spontaneous pneumothorax (PSP) is a very common disease and recurrence is a major concern for the post-first-time victims. Owing to the convenience and popularity of video-assisted thoracoscopic surgery (VATS), should we still wait for recurrence before we perform this minimal invasive procedure to cure the disease? Between 1997 and 2002, 51 patients of PSP from the first episode received VATS the day after their admission at Kaohsiung Medical University Hospital. Forty-five patients (90%) were found to have blebs (mostly above the upper lobe). They all received wedge resection plus pleural abrasion. No mortality was recorded. The average postoperative hospital stay was 4 days. After a follow-up period of 38 months, no recurrence or complication was found. The patients are now living in good health. We found a high percentage of blebs. These are possible causes of subsequent recurrence. Surgical intervention with VATS for the first episode of PSP is safe, effective, and cosmetically excellent. The most important thing is that the fear of recurrence is finally resolved.     

Pediatric empyema--an algorithm for early thoracoscopic intervention.

INTRODUCTION: The management of pediatric empyema remains controversial. We contend that early thoracoscopic intervention results in shorter hospital stays, decreased morbidity, and superior outcomes. We propose an algorithm using early image-guided thoracoscopy as an effective treatment for pediatric empyema. METHODS: Consecutive pediatric empyemas treated from November 1997 to April 2001 using a prospective management algorithm were reviewed. Demographic data, days to diagnosis, days to surgery, length of stay, chest tube days, complications, and follow-up were recorded. RESULTS: Twenty-two children with 24 empyemas were treated using this algorithm. Their mean age was 49 months. Mean days to diagnosis was 11 and from diagnosis to surgery was 3. Imaging included chest radiography (CXR) in all, ultrasound in 17 (77%), and computed tomography (CT) scan in 13 (59%). One thoracoscopy was converted to a mini-thoracotomy because of difficulty with ventilation. Chest tube removal averaged 3 days with an average length of stay of 13 days. One patient required a second thoracoscopy for recurrent empyema, and 1 patient developed a contralateral empyema. No other complications or deaths occurred. Follow-up in 19 of 22 (86%) children at 5 months revealed no recurrences or mortality. CONCLUSION: This treatment algorithm, using early image-guided thoracoscopy, is a safe and effective means of managing pediatric empyema, while shortening hospital stay and avoiding the morbidity of thoracotomy.     

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.
