Assessment and review of treatment for secondary spontaneous pneumothorax using medical thoracoscopy-assisted argon plasma coagulation in association with autologous blood pleurodesis.

ABSTRACT:

Aims

To evaluate the efficacy of medical thoracoscopy-assisted argon plasma coagulation in association with autologous blood pleurodesis in spontaneous pneumothorax.

Patients and methods

Three male patients with spontaneous pneumothorax were treated; medical thoracoscopy-assisted argon plasma coagulation combined with autologous blood pleurodesis was conducted for all patients whose duration of the air leak exceeded 7 days. We systematically reviewed all of the relevant literature to analyze and sum up the treatments of secondary spontaneous pneumothorax.

Results

The air leaks were all sealed and no recurrence of pneumothorax was reported. No complications of fever, bleeding, or signs of infection were observed during the process.

Conclusion

The authors believe that the combination of medical thoracoscopy-assisted argon plasma coagulation and autologous blood pleurodesis is safe and effective. However, due to the number of patients included in this uncontrolled case study, more cases will be collected in the future.The reviews of this paper are available via the supplemental material section.

Project description:BackgroundPrimary spontaneous pneumothorax is managed initially with observation and chest tube placement, followed by surgical intervention in select cases. With little currently published evidence, the role of surgical pleurodesis or pleurectomy to reduce primary spontaneous pneumothorax recurrence is unclear. This study compares the recurrence rates of primary spontaneous pneumothorax following bullectomy alone versus bullectomy with pleurodesis or pleurectomy.MethodsA retrospective review was performed at a quaternary hospital for all patients undergoing surgery for primary spontaneous pneumothorax between June 2006 and December 2018. Patient demographics, disease severity, operative technique, and time between initial surgery and recurrence were recorded. Standard statistical techniques were used for univariable and multivariable analyses.ResultsOf 222 total included patients, 28 required a second surgery: 4 (1.8%) for prolonged air leak and 24 (10.8%) for recurrent pneumothorax. The median time from first to second surgery was 363 days and 35.7% of recurrences did not present until after two years. Age, sex, smoking, year of initial surgery, disease severity, and surgical technique did not significantly affect recurrence rate on univariable analysis. On multivariable analysis, the odds ratios of recurrence for bullectomy with mechanical pleurodesis or pleurectomy were respectively 0.82 and 0.15 (P=0.218), compared to bullectomy alone. Combined bullectomy, pleurectomy, and pleurodesis was most effective (0/18, 0%).ConclusionsBullectomy with pleurectomy and pleurodesis demonstrated a 0% recurrence rate for the treatment of primary spontaneous pneumothorax in this study. Statistical significance was not achieved in univariable or multivariable analyses comparing recurrence rates for the surgical approaches. A multi-center randomized controlled trial with longer follow-up than previously performed is needed to confirm these preliminary findings and optimize surgical management of primary spontaneous pneumothorax.

Project description:BackgroundWith the adoption of high-tech thoracoscopic surgical instruments, video-assisted thoracoscopic surgery (VATS) has gradually replaced traditional thoracotomy and is used in the clinical treatment of spontaneous pneumothorax.MethodsThe composite logic retrieval and Boolean logic retrieval methods were adopted for this meta-analysis. Databases such as PubMed, Medline, Cochrane Library, CNKI, Wanfang, VIP, and Google Scholar were searched using the combination of search terms "Video-assisted thoracoscopic surgery", "spontaneous pneumothorax", and "thoracotomy". Literatures which used video-assisted thoracoscopic surgery for spontaneous pneumothorax as the experimental group were screened. The software RevMan 5.3 provided by the Cochrane system was employed for meta-analysis.ResultsA total of 12 studies were included. After the meta-analysis, heterogeneity testing of the operation time in 8 studies showed that Tau2 =29.99, Chi2 =16.99, degrees of freedom (df) =7, I2=59%>50%, and the operation time of participants in the experimental group was considerably inferior to that of control group. The mean difference (MD) was -31.02, 95% confidence interval (95% CI: -36.07 to -25.97), Z=12.03, P<0.0001. The heterogeneity test of the length of hospital stay in 9 studies showed that Tau2 =4.41, Chi2 =122.58, df =8, I2=59%>50%, P<0.01, and the length of hospital stay of participants in the experimental group was remarkably shorter than that of the control group. The MD was -7.29, 95% CI: (-8.76 to -5.82), Z=9.74, and P<0.01. The heterogeneity test of the bleeding volume in 6 studies showed that Tau2 =191.74, Chi2 =27.65, df =5, I2=82%>50%, P<0.01, and the bleeding volume of participants in the experimental group was remarkably lower in contrast to that of the control group. The MD was -65.48, 95% CI: (-77.84 to -53.13), Z=10.39, and P<0.01. The heterogeneity test of the chest tube removal time in 7 studies showed that Tau2 =0.29, Chi2 =28.27, df =6, I2=79%>50%, P<0.05, and the chest tube removal time of participants in the experimental group was substantially lower in contrast to that of the control group. The MD was -3.10, 95% CI: (-3.56 to -2.64), Z=13.30, P<0.01.DiscussionThis meta-analysis confirmed that VATS for spontaneous pneumothorax is better than other surgical methods.

Project description:BackgroundA prolonged air leak (PAL) is the most frequent complication after pulmonary resection. This study aimed to assess the safety and efficacy of autologous blood patch pleurodesis (ABPP) to treat PAL.MethodsA prospectively maintained database identified patients with a PAL after pulmonary resection for lung cancer between 2015-2019. In this observational cohort study, clinical data were collected to retrospectively compare patients undergoing ABPP to no ABPP in a propensity-matched analysis. Kaplan Meier estimates and Cox models accounting for inverse probability weighting (IPTW) were used to assess the association of ABPP with each outcome.ResultsOf the 740 patients undergoing lung resection, 110 (15%) were identified as having a PAL at postoperative day (POD) 5. There was no difference between baseline characteristics among those undergoing ABPP (n=34) versus no ABPP (n=76). Propensity-weighted analysis did not reveal a significant association of ABPP treatment with in-hospital complication (P=0.18), hospital length of stay (LOS) (P=0.13), or post-discharge complication (P=0.13). However, ABPP treatment was associated with a lower risk of hospital readmission [P=0.02, hazard ratio (HR) 0.16] and reoperation for air leak or empyema (P=0.05, HR 0.11). Although not statistically significant, the mean chest tube (CT) removal of 11 days for the ABPP group was less than the no ABPP group (16 days) (P=0.14, HR 1.5-2). Those treated with ABPP were less likely to be discharged with a CT (ABPP 7/34, 21% vs. no ABPP 40/76, 53%). There was no statistical difference in empyema development between groups (ABPP 0/34, 0% vs. no ABPP 4/76, 5%, P=0.39, HR 0.24).ConclusionsABPP administration is safe compared to traditional PAL management. In a retrospective propensity-matched analysis, postoperative patients treated with ABPP required less readmission and reoperation for PAL. Larger powered randomized trials may demonstrate the magnitude of benefit from treatment with ABPP.

Project description:BackgroundAlthough recurrence is included in surgical indications, there is no definitive guideline for managing recurrent spontaneous pneumothorax (SP) according to characteristics of recurrence, such as the type [primary SP (PSP) or secondary SP (SSP)] and recurrence-free interval (RFI). Actually, some patients with early cessation of air leak after closed thoracostomy tubes, a long RFI, or medical comorbidities are often managed conservatively without surgery. However, the validity of this management is unclear. The aims of the present study are to analyze treatment outcomes for recurrent SP according to the type of SP and RFI, and to check the validity of conservative treatment for patients according to type of SP and RFI.MethodsWe included 1,250 consecutive cases (624 right sided and 626 left side cases for the first episode) who were hospitalized and treated from January 2012 to June 2018. To investigate recurrence according to treatment modality (surgical or conservative treatment), we estimated RFI in each group during the observation period. RFI was measured from the completion of treatment to recurrence or last follow-up. We divided patients into two groups [the early (EG) and the late (LG) recurrence group] according to 1-year. Recurrence was defined as a subsequent episode of an ipsilateral SP, while a contralateral SP was regarded as an independent case in the present study. RFI between subgroups was compared using the Kaplan-Meier method with the log-rank test. A P value less than 0.05 (two-sided) was regarded as statistically significant.ResultsRecurrence occurred in 47 cases after surgical intervention for the first episode (585 cases). Recurrence occurred in 265 cases after conservative treatment for the first episode of SP (665 cases). For the first episode, the surgical group (SG) had a significantly longer RFI than the conservative group (CG), regardless of the type (both, P<0.001). Conservative treatment and surgical intervention for the second episode after conservative treatment for the first episode were performed in 98 and 167 cases, respectively. For the second episode after conservative treatment for the first episode, SG also had a significantly longer RFI than CG, regardless of the types (PSP P<0.001, SSP P=0.031). To check the validity of conservative treatment for patients with a long RFI, we analyzed recurrence by dividing patients into two groups according to one-year RFI. For PSP, the early recurrence group (EG, RFI ?1 year) had 99 cases and the late recurrent group (LG, RFI >1 year) had 67 cases. SG had a significantly longer RFI than CG in both EG and LG (EG, P<0.001 and LG, P=0.001). In addition, for SSP, there were 67 cases of EG and 32 cases of LG, SG had significantly longer RFIs than CG in EG (P=0.007). However, there was no significant difference in RFI between SG and CG in LG (P=0.748).ConclusionsThe present study revealed diversity of management outcomes according to characteristics of recurrence and provides some evidences of the validity of conservative treatment in recurrent SSP with a long RFI. Further large-scale prospective randomized trials are required to validate these findings.
