Which Role for Muscle-Sparing Posterolateral Thoracotomy in the Treatment of Spontaneous Pneumothorax? Surg J (N Y) 2023; 9:e149-e155. [PMID: 38197090 PMCID: PMC10754642 DOI: 10.1055/s-0043-1770954] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Accepted: 05/26/2023] [Indexed: 01/11/2024] Open
Abstract
Objective This study aims to show the place of muscle-sparing posterolateral thoracotomy in the treatment of spontaneous pneumothorax. Methods It was a single-center study performed in the Department of Thoracic Surgery of Teaching hospital Hassan II of Fez for 8 years. We adopted the nosological definition, which classifies spontaneous pneumothorax into three categories. We included patients over 15 years of age with primary or secondary spontaneous pneumothorax operated by posterolateral thoracotomy without muscle section, and we analyzed the specific indications of this approach. It included 49 patients with primary or secondary spontaneous pneumothorax, operated by muscle-sparing posterolateral thoracotomy. Data were collected from regularly updated computer files of patients, entered by Excel 2013, and analyzed using SPSS.20 software. These data are: epidemiological, clinical, radiological, surgical exploration, surgical procedure, the result of the surgery and the evolution. Results The average age was 42 years. Smoking was found in 61% of cases and pulmonary tuberculosis in 10% of cases. Thoracic computed tomography (CT) showed bullae and blebs in 31% of cases, pleural adhesions and pachypleuritis in 50% of cases, and hydropneumothorax with pachypleuritis in 37% of cases. There is a statistical correlation between pleuropulmonary decortication and pachypleuritis ( p = 0.002) or hydropneumothorax ( p = 0.001) on CT. Bullae and blebs resection was performed in 53% of cases and pleuropulmonary decortication in 63% of cases. A right pleuropneumonectomy was performed in one case. The follow-up was uneventful in 82% of cases. Conclusion Muscle-sparing posterolateral thoracotomy remains the best approach and leads to good results.

Abstract
Abstract
Background
To monitor dypsnea and mortality at 5 and 10 years, respectively, after surgical treatment of tuberculosis-destroyed lung (TDL) patients.
Methods
TDL patients treated surgically at Beijing Chest Hospital from November 2007 to June 2019 were monitored in this observational study. Follow-up assessments of respiratory function indicators and survival conducted 5 and 10 years post-surgery led to patient grouping based on mMRC score into a dyspnea group (mMRC ≥ 1) and a non-dyspnea group (mMRC = 0). Cox regression analysis detected effects of patient demographics, clinical characteristics, surgical factors and respiratory function on 5 year post-surgical survival.
Results
By study completion (June 30, 2020), 32 of 104 patients were lost and 72 completed follow-up for a study total of 258.9 person-years. 45 patients (62.5%, 45/72) had mMRC scores of 0, while 12 (16.7%, 12/72), 21 (36.2%, 21/58) and 27 (60.0%, 27/45) patients exhibited dyspnea by 1, 3 and 5 years post-surgery, respectively. Low lung carbon monoxide diffusion score (DLCO% pred) and scoliosis contributed to dyspnea occurrence.
Conclusions
Most TDL patients lacked subjective dyspnea signs post-surgery, while dyspnea rates increased with time. Preoperative low lung diffusion function and Scoliosis were associated with factors for postoperative dyspnea. Surgical treatment increased TDL patient survival overall.

Abstract
Africa has a high burden of tuberculosis, which is the most important risk factor for chronic pulmonary aspergillosis (CPA). Our goal was to systematically evaluate the burden of CPA in Africa and map it by country. We conducted an extensive literature search for publications on CPA in Africa using the online databases. We reviewed a total of 41 studies published between 1976 and 2021, including a total of 1247 CPA cases from 14 African countries. Most of the cases came from Morocco (n = 764, 62.3%), followed by South Africa (n = 122, 9.9%) and Senegal (n = 99, 8.1%). Seventeen (41.5%) studies were retrospective, 12 (29.3%) were case reports, 5 case series (12.2%), 5 prospective cohorts, and 2 cross-sectional studies. The majority of the cases (67.1%, n = 645) were diagnosed in men, with a median age of 41 years (interquartile range: 36–45). Active/previously treated pulmonary tuberculosis (n = 764, 61.3%), human immunodeficiency virus infection (n = 29, 2.3%), diabetes mellitus (n = 19, 1.5%), and chronic obstructive pulmonary disease (n = 10, 0.8%) were the common co-morbidities. Haemoptysis was the most frequent presenting symptom, reported in up to 717 (57%) cases. Smoking (n = 69, 5.5%), recurrent lung infections (n = 41, 3%) and bronchorrhea (n = 33, 3%) were noted. This study confirms that CPA is common in Africa, with pulmonary tuberculosis being the most important risk factor.

Abstract
Chronic pulmonary aspergillosis (CPA) is an emerging fungal infectious disease of public health importance. We conducted a systematic review of studies reporting the outcomes of patients with CPA managed surgically in Africa. A search of Medline, Embase, Web of Science, Google Scholar and African Journals Online was conducted to identify studies indexed from inception to June 2021 that examined surgical management of CPA in Africa. All articles that presented primary data, including case reports and case series, were included. We excluded review articles. A total of 891 cases (557 males (62.5%), mean age 39.3 years) extracted from 27 eligible studies published between 1976 and 2020 from 11 African countries were included. Morocco (524, 59%) and Senegal (99, 11%) contributed the majority of cases. Active or previous pulmonary tuberculosis was reported in 677 (76.0%) cases. Haemoptysis was reported in 682 (76.5%) cases. Lobectomy (either unilateral or bilateral, n = 493, 55.3%), pneumonectomy (n = 154, 17.3%) and segmentectomy (n = 117, 13.1%) were the most frequently performed surgical procedures. Thirty (4.9%) cases from South Africa received bronchial artery embolisation. Empyema (n = 59, 27.4%), significant haemorrhage (n = 38, 173.7%), incomplete lung expansion (n = 26, 12.1%) and prolonged air leak (n = 24, 11.2%) were the most frequent complications. Overall, 45 (5.1%) patients died. The causes of death included respiratory failure (n = 14), bacterial superinfection/sepsis (n = 10), severe haemorrhage (n = 5), cardiopulmonary arrest (n = 3) and complications of chronic obstructive pulmonary disease (n = 3). The cause of death was either unknown or unspecified in 9 cases. We conclude that surgical treatment had very low mortality rates and maybe considered as first-line management option in centres with experience and expertise in Africa.

Abstract
Background To evaluate the efficacy and safety of surgical treatment of tuberculosis destroyed lung (TDL), and the influence of chronic pulmonary aspergillosis (CPA) on the outcomes of surgical treatment of TDL. Methods We performed a retrospective analysis of 113 patients with TDL who underwent surgical treatment from January 2005 to December 2019. Among them, 30 of these cases were complicated with CPA. The patients were divided into two groups: TDL group and TDL + CPA group. We analyzed the effectiveness and safety of surgical treatment of TDL, and further compared the effectiveness and safety of surgical treatment of TDL with or withoutthe presence of CPA. Results The TDL + CPA group had a significantly higher age (P=0.003), symptoms of hemoptysis (P=0.000), and a higher proportion of patients with preoperative serum albumin <30 g/L (P=0.014) as compared with TDL group. For all enrolled patients, the incidence of severe postoperative complications was 12.4% (14/113) and the postoperative mortality within 30 days after discharge was 4.4% (5/113). 86.7% (98/113) of the patients recovered and discharged, the incidence of severe postoperative complications in the TDA + CPA group was higher than that of TDL group (23.3% vs 8.4%, P = 0.034), although there was no difference in mortality between the two groups (P = 1.000). A binary logistic regression analysis showed that the independent risk factors for severe postoperative complications were male (OR 25.24, 95% CI 2.31–275.64; P = 0.008) and age ≥ 40 years (OR 10.34, 95% CI 1.56–68.65; P = 0.016). Conclusion Surgical treatment for patients with TDL is effective with an acceptable mortality rate whether or not the disease is complicated with CPA. The independent risk factors identified for severe postoperative complications in patients with TDL were male and ≥ 40 years old. It implies that when treating patients with TDA + CPA, particular attention should be paid to these patients who have these independent risk factors to avoid a poor outcome.

Abstract
Background Treatment of tuberculous-destroyed lung (TDL) with pleuropulmonary resection is challenging. Pulmonary hemorrhage is a frequent complication of this surgical procedure. Continuous efforts have been made to investigate clinical procedures that may reduce intraoperative bleeding effectively. In this study, we evaluated the feasibility and safety of regional arterial embolization before pleuropulmonary resection in patients with TDL. Methods The clinical data of 32 patients with TDL were retrospectively reviewed and analyzed. These patients were admitted to the hospital between July 2009 and November 2016. All of the patients had moderate to massive hemoptysis and received regional arterial embolization in affected areas. Then, these patients underwent pleuropulmonary resection within 1 week to 2 months after embolization. Results The results showed that 25 patients (78.1%) had bronchial artery, and all patients had non-bronchial systemic artery found in affected areas. Mild to moderate chest pain was reported in 6 patients, and fever was reported in 2 patients. Intraoperative blood loss during pleuropulmonary resection in patients who had received preoperative regional arterial embolization was 625.6 ± 352.6 ml. Duration of the operation was 120.3 ± 75.2 min. Bronchopleural fistulae and empyema were found in 3 cases (9.4%). Conclusion Performance of regional arterial embolization before pleuropulmonary resection offers a safe and feasible option that reduces intraoperative blood loss and shortens operative time in patients with TDL.

Abstract
This study aimed to determine the radiological features of microscopy-positive pulmonary tuberculosis (TB). We conducted a retrospective study, analyzing radiographical imaging of patients with microscopy-positive pulmonary tuberculosis between 15 November 2015 and 15 March 2016. The medical records of 66 patients meeting the inclusion criteria were selected, 81.8% of which belonged to men. The average age of patients was 37.5 ± 14.9 years. Patients had variable parenchymal lesions dominated by infiltrated lesions in 84.8% (CI 95%; 73.9-92.4%) of cases, followed by alveolar syndrome in 68.2% (CI95%; 55.5-79.1%) of cases. Lesions were extensive in 71.2% (CI 95%; 58.7-81.7%) of cases and bilateral in 45.4% (CI 95%; 31.1-58.1%) of cases. These radiological abnormalities occurred in 52.2% (CI 95%; 36.9 - 67.1%) of cases in undernourished patients. In 22.7% (CI 95%; 13.3-34.7%) of cases, these lesions were secondary to an episode of pulmonary tuberculosis; 34.8% (IC95; 23.5 - 47.5%) of patients were regular tobacco smokers consuming, on average, 17 tobacco packs per year (±11.3). TB recurrences were more frequent in patients with a history of smoking versus non-smokers (26.1% versus 20.9%, p < 0.42 respectively). HIV-1 serology test was positive in 7.6% of cases. This study highlights the importance of suspecting pulmonary tuberculosis in young undernourished patients, having a history of smoking, with infiltrated lesions associated or not with cavitary lesions on radiographic examination and living in TB epidemic area.

Abstract
Trace elements play an important role in tuberculosis infection because their deficiencies can be associated with impaired immunity. Blood samples were collected from a total of 320 active pulmonary tuberculosis patients and healthy individuals. The serum concentrations of Zinc, Iron, Copper, Calcium, lead, Arsenic and Selenium were analyzed by atomic absorption spectrometry. The levels of trace elements were measured after 2, 4 and 6 months of anti-TB treatment initiation in TB infected groups. Compared to the control group, the concentrations of Zinc, Selenium, and Iron were significantly lower (P < 0.001) in tuberculosis patients; however, that of Arsenic, Lead, and copper was significantly higher (P < 0.001) in the serum of patients. Cu/Zn and Cu/Se ratios were also significantly higher (P < 0.001) in TB patients compared to the control group. In addition, serum concentration calcium was similar in both TB patients and healthy controls. Our results indicated that trace elements concentrations in tuberculosis patients are related to each element role in immune system. Wherever the element is essential for the pathogenesis of bacteria, its concentration will remain low; and contrariwise, when the element is toxic for the bacteria, its level will be regulated up to provide a perfect condition for bacterial growth.
