RESUMO
Mesothelioma affects mostly older individuals who have been occupationally exposed to asbestos. The global mesothelioma incidence and mortality rates are unknown, because data are not available from developing countries that continue to use large amounts of asbestos. The incidence rate of mesothelioma has decreased in Australia, the United States, and Western Europe, where the use of asbestos was banned or strictly regulated in the 1970s and 1980s, demonstrating the value of these preventive measures. However, in these same countries, the overall number of deaths from mesothelioma has not decreased as the size of the population and the percentage of old people have increased. Moreover, hotspots of mesothelioma may occur when carcinogenic fibers that are present in the environment are disturbed as rural areas are being developed. Novel immunohistochemical and molecular markers have improved the accuracy of diagnosis; however, about 14% (high-resource countries) to 50% (developing countries) of mesothelioma diagnoses are incorrect, resulting in inadequate treatment and complicating epidemiological studies. The discovery that germline BRCA1-asssociated protein 1 (BAP1) mutations cause mesothelioma and other cancers (BAP1 cancer syndrome) elucidated some of the key pathogenic mechanisms, and treatments targeting these molecular mechanisms and/or modulating the immune response are being tested. The role of surgery in pleural mesothelioma is controversial as it is difficult to predict who will benefit from aggressive management, even when local therapies are added to existing or novel systemic treatments. Treatment outcomes are improving, however, for peritoneal mesothelioma. Multidisciplinary international collaboration will be necessary to improve prevention, early detection, and treatment.

BACKGROUND: The role of surgery in pleural mesothelioma remains controversial. It may be appropriate in highly selected patients as part of a multimodality treatment including chemotherapy. Recent years have seen a shift from extrapleural pleuropneumonectomy toward extended pleurectomy/decortication. The most optimal sequence of surgery and chemotherapy remains unknown. METHODS: EORTC-1205-LCG was a multicentric, noncomparative phase 2 trial, 1:1 randomising between immediate (arm A) and deferred surgery (arm B), followed or preceded by chemotherapy. Eligible patients (Eastern Cooperative Oncology Group 0-1) had treatment-naïve, borderline resectable T1-3 N0-1 M0 mesothelioma of any histology. Primary outcome was rate of success at 20â weeks, a composite end-point including 1) successfully completing both treatments within 20â weeks; 2) being alive with no signs of progressive disease; and 3) no residual grade 3-4 toxicity. Secondary end-points were toxicity, overall survival, progression-free survival and process indicators of surgical quality. FINDINGS: 69 patients were included in this trial. 56 (81%) patients completed three cycles of chemotherapy and 58 (84%) patients underwent surgery. Of the 64 patients in the primary analysis, 21 out of 30 patients in arm A (70.0%; 80% CI 56.8-81.0%) and 17 out of 34 patients (50.0%; 80% CI 37.8-62.2%) in arm B reached the statistical end-point for rate of success. Median progression-free survival and overall survival were 10.8 (95% CI 8.5-17.2) months and 27.1 (95% CI 22.6-64.3) months in arm A, and 8.0 (95% CI 7.2-21.9) months and 33.8 (95% CI 23.8-44.6) months in arm B. Macroscopic complete resection was obtained in 82.8% of patients. 30- and 90-day mortality were both 1.7%. No new safety signals were found, but treatment-related morbidity was high. INTERPRETATION: EORTC 1205 did not succeed in selecting a preferred sequence of pre- or post-operative chemotherapy. Either procedure is feasible with a low mortality, albeit consistent morbidity. A shared informed decision between surgeon and patient remains essential.

BACKGROUND: The role of the number of involved structures (NIS) in thymic epithelial tumors (TETs) has been investigated for inclusion in future staging systems, but large cohort results still are missing. This study aimed to analyze the prognostic role of NIS for patients included in the European Society of Thoracic Surgeons (ESTS) thymic database who underwent surgical resection. METHODS: Clinical and pathologic data of patients from the ESTS thymic database who underwent surgery for TET from January 2000 to July 2019 with infiltration of surrounding structures were reviewed and analyzed. Patients' clinical data, tumor characteristics, and NIS were collected and correlated with CSS using Kaplan-Meier curves. The log-rank test was used to assess differences between subgroups. A multivariable model was built using logistic regression analysis. RESULTS: The final analysis was performed on 303 patients. Histology showed thymoma for 216 patients (71.3%) and NET/thymic carcinoma [TC]) for 87 patients (28.7%). The most frequently infiltrated structures were the pleura (198 cases, 65.3%) and the pericardium in (185 cases, 61.1%), whereas lung was involved in 96 cases (31.7%), great vessels in 74 cases (24.4%), and the phrenic nerve in 31 cases (10.2%). Multiple structures (range, 2-7) were involved in 183 cases (60.4%). Recurrence resulted in the death of 46 patients. The CSS mortality rate was 89% at 5 years and 82% at 10 years. In the univariable analysis, the favorable prognostic factors were neoadjuvant therapy, Masaoka stage 3, absence of metastases, absence of myasthenia gravis, complete resection, thymoma histology, and no more than two NIS. Patients with more than two NIS presented with a significantly worse CSS than patients with no more than two NIS (CSS 5- and 10-year rates: 9.5% and 83.5% vs 93.2% and 91.2%, respectively; p = 0.04). The negative independent prognostic factors confirmed by the multivariable analysis were incomplete resection (hazard ratio [HR] 2.543; 95% confidence interval [CI] 1.010-6.407; p = 0.048) and more than two NIS (HR 1.395; 95% CI 1.021-1.905; p = 0.036). CONCLUSIONS: The study showed that more than two involved structures are a negative independent prognostic factor in infiltrative thymic epithelial tumors that could be used for prognostic stratification.

BACKGROUND: Information regarding late recurrence after pulmonary resection for non-small cell lung cancer (NSCLC) is limited. This study aimed to analyze the risk factors for late recurrence after surgery for NSCLC in the current era. PATIENTS AND METHODS: We conducted a retrospective study of patients who underwent complete resection for pathological I-III NSCLC between 2006 and 2015. Late recurrence was defined as a recurrence that met the following conditions: (1) the patient underwent chest computed tomography (CT) at or after 54 months after surgery and recurrence was not detected at that time, and (2) recurrence that occurred more than 5 years after surgery. The factors influencing late recurrence, relapse-free survival (RFS), and overall survival (OS) after surgery were analyzed. RESULTS: A total of 1275 with 5-year relapse-free survival after surgery were enrolled in this study. The mean age of the patients was 66.4 years and 54% of the patients were men. The median interval between surgery and the latest follow-up examination was 98 months. In total, 35 patients (2.7%) experienced late recurrence and 138 patients have died thus far. The cumulative recurrence, RFS, and OS rates at 10 years were 3.9%, 84.9%, and 86.3%, respectively. A multivariate analysis revealed that pleural invasion was an independent risk factor for late recurrence. Pleural invasion was a poor prognostic factor for both RFS and OS. CONCLUSIONS: Pleural invasion was a predictor of late recurrence. Age > 67 years, preoperative serum carcinoembryonic antigen (CEA) > 5 ng/ml, non-adenocarcinoma, and pleural invasion were poor prognostic factors for RFS.

OBJECTIVES: The rates of postoperative mortality and morbidity are high in patients with malignant pleural mesothelioma (MPM). Therefore, it is important to identify variables that increase the risk of postoperative complications. Pleural thickness has recently been identified as a prognostic indicator in patients with MPM. The aim of this study was to investigate clinical variables, including pleural thickness, that contribute to postoperative complications in patients with MPM. PATIENTS AND METHODS: A total of 47 patients who underwent surgical excision of MPM between 2005 and 2021 were enrolled in this study. Correlations between postoperative complications within 90 days of surgery and preoperative clinical factors were investigated. RESULTS: A total of 27 patients underwent extrapleural pneumonectomy (EPP), and the remaining 20 underwent pleurectomy/decortication (P/D). Macroscopic complete resections were obtained in all but three patients. Of the 47 patients, 23 (49%) experienced postoperative complications of grade 3 or worse. The major complication in patients with EPP was respiratory failure (n = 6), whereas the major complication in patients with P/D was prolonged air leakage (n = 7). Univariate logistic regression analysis found a correlation between postoperative complications and age, surgical side, and pleural thickness, while multivariate logistic regression analysis found surgical side (p = 0.04, 95% Cl 1.10-21.71, OR 4.90) and pleural thickness (p = 0.03, 95% Cl 1.21-23.00, OR 5.26) to significantly influence the occurrence of postoperative complications. CONCLUSIONS: Pleural thickness has a significant effect on the occurrence of postoperative complications. Patients with thick pleura on the right side are at greater risk of postoperative complications.

OBJECTIVE: Mid-point transverse process to pleura (MTP) block is a new regional analgesia technique. This study aimed to assess the perioperative analgesic effects of MTP block in children undergoing open-heart surgery. DESIGN: A single-center, randomized, double-blinded, controlled, superiority study. SETTING: At a University Children's Hospital. PARTICIPANTS: Fifty-two patients aged 2 to 10 years who underwent open-heart surgery. INTERVENTIONS: Patients were randomized to receive either bilateral MTP block or no block (control). MEASUREMENTS AND MAIN RESULTS: The primary outcome was fentanyl consumption in the first postoperative 24 hours. The secondary outcomes were intraoperative fentanyl consumption, modified objective pain score (MOPS) measured at 1, 4, 8, 16, and 24 hours after extubation, and the duration of stay in the intensive care unit (ICU). The mean (SD) postoperative fentanyl consumption (µg/kg) in the first 24 hours was significantly reduced in the MTP block group (4.4 ± 1.2) compared to the control group (6.0 ± 1.4, p < 0.001). The mean (SD) intraoperative fentanyl requirement (µg/ kg) was significantly reduced in the MTP block group (9.1 ± 1.9) compared to the control group (13.0 ± 2.1, p < 0.001). The MOPS was significantly reduced in the MTP block group compared to the control group at 1, 4, 8, and 16 hours after extubation but was comparable in both groups at 24 hours. The mean (SD) duration of ICU stay (hours) was significantly reduced in the MTP block group (25.0 ± 2.9) compared to the control group (30.7 ± 4.2, p < 0.001). CONCLUSIONS: Single-shot bilateral ultrasound-guided MTP block in children undergoing cardiac surgery reduced the mean fentanyl consumption in the first postoperative 24 hours, intraoperative fentanyl requirements, pain score at rest, time to extubation, and duration of ICU stay.

Percutaneous or transbronchial markings are performed to localize pulmonary nodules preoperatively. We present a novel intraoperative procedure that utilizes virtual thoracoscopic imaging-assisted pleural marking. In this procedure, a virtual thoracoscopic image is created preoperatively, and the coordinates of the pleural point above the tumor are determined. The pleural marker is intraoperatively placed on the coordinates, and dye is transferred to the visceral pleura with two lung ventilations. We present the specific procedures and countermeasures for cases when nodules are not palpable. Additionally, we present a comparison between the various methods of preoperative marking and this method.

BACKGROUND: Thymoma patients with pleural dissemination are difficult to manage, and their treatment strategy remains undefined. This study aimed to investigate the clinicopathologic features of these patients, focusing on the association between the depth of pleural invasion and prognosis. METHODS: Between 2003 and 2019, the study identified 120 disseminated lesions in 20 thymoma patients. Seven patients had de novo stage IVa thymoma and 13 were recurrent cases. Extrapleural pneumonectomy was performed for 8 patients and debulking surgery for 12 patients. Invasion depth of pleural tumors was classified into two groups: when the disseminated tumors invaded the pleura beneath the elastic layer, the tumor was diagnosed as Da, and when the disseminated tumors invaded the pleura beyond the elastic layer, the tumor was diagnosed as Db. RESULTS: Of 120 nodules, 31 (26%), found in eight patients with recurrent malignancies, were classified as Db. The pathologic status of the surgical margin (PSM) was positive in eight patients, seven of whom had Db nodules. The 5-year overall survival (OS) rate was 100% in the Da group and 75% in the Db group (P = 0.02). The 5-year progression-free survival (PFS) rate was 66.7% in the Da group and 25% in the Db group (P = 0.02). Cox univariate analysis showed that PFS was significantly influenced by the depth of invasion (P = 0.04) and PSM (P = 0.03). CONCLUSION: Depth of pleural invasion may influence survival outcomes for thymoma patients with pleural dissemination. The patients in this study with Da-disseminated nodules had an increased probability of a longer OS and PFS and tended to achieve negative PSM compared with the patients with Db.

OBJECTIVES: This study aimed to explore the effect of suturing upper mediastinum pleura on postoperative complications, surgery-related mortality, and hospital stay. METHODS: Four hundred and thirty-eight patients with esophageal cancer who underwent esophagectomy were identified. Patients were divided into two groups: those in the test group who received reconstruction of upper mediastinal pleura, those in the conventional group who did not. The incidence of postoperative complications, surgery-related mortality, and hospital stay were compared. To reduce the impact of confounding factors, a propensity score matching (PSM) method was performed. RESULTS: A total of 273 patients were treated with suturing upper mediastinal pleura and 165 were not. After PSM, compared with the conventional group, the incidence of atelectasis (7.2% vs. 1.4%, p = 0.035), anastomotic leakage (5.8% vs. 0.7%, p = 0.036), and delayed gastric emptying (10.8% vs. 3.6%, p = 0.034) were significantly lower in the test group. And suturing the upper mediastinal pleura could reduce the severity of leakage (p = 0.045), consistent with the results before PSM. Moreover, there were no significant differences in the incidence of other complications, postoperative hospital stay, and 30-day mortality (all p > 0.05). CONCLUSIONS: In this study, suturing the upper mediastinal pleura can reduce the incidence of atelectasis, anastomotic leakage, and delayed gastric emptying, and the severity of leakage, without increasing the incidence of other complications, surgery-related death, and postoperative hospital stay.

OBJECTIVE: Visceral pleural invasion is an adverse prognostic factor in non-small-cell lung cancer, but its value in small-cell lung cancer remains unclear. Thus, we investigated the prognostic impact of visceral pleural invasion in patients with surgically resected small-cell lung cancer. METHODS: We queried the Surveillance, Epidemiology and End Results Program database for patients diagnosed with stages I-III (excluding N3 and nodal metastasis cannot be evaluated (NX)) small-cell lung cancer from 2004 to 2016, who underwent surgery. To minimize unbalanced baseline characteristics between the visceral pleural invasion and non-visceral pleural invasion groups, one-to-one propensity score matching was employed. A Kaplan-Meier curve was used to compare the overall survival of the two cohorts. A Cox proportional hazards model was adopted to determine the impact of visceral pleural invasion on survival. RESULTS: Of the 1416 patients included, 372 (26.27%) presented with visceral pleural invasion. Patients with visceral pleural invasion showed significantly worse overall survival (P < 0.001) both before and after propensity score matching. Multivariable analysis indicated that visceral pleural invasion was an independent adverse factor affecting survival. Patients with visceral pleural invasion showed poorer overall survival (hazard ratio: 1.44; 95% confidence interval: 1.17-1.76; P < 0.001). Subgroup analyses revealed that the non-visceral pleural invasion group was associated with favourable overall survival in N0 patients (P = 0.003) but not in N1 or N2 patients (P = 0.774 and 0.248, respectively). Patients diagnosed at younger ages, females, lower N stage, resection with a lobectomy and adjuvant chemotherapy were associated with improved overall survival in the visceral pleural invasion group. CONCLUSIONS: Visceral pleural invasion was an indicator of a poor prognosis for small-cell lung cancer, especially in those with N0 disease. Adjuvant chemotherapy significantly improves patient outcomes for patients with visceral pleural invasion.

OBJECTIVE: To assess the effect and safety of subpleural multisite anesthesia based on the area of thermal radiation during CT-guided lung malignancy microwave ablation (MWA) on the incidence of moderate or severe pain and the analgesic drug usage. MATERIALS AND METHODS: Consecutive patients with lung malignancies were retrospectively evaluated between January 2016 and December 2019. Patients undergoing CT-guided lung malignancy MWA were either given in the method of (a) standard subpleural puncture point anesthesia between January 2016 and June 2018 and (b) subpleural multisite anesthesia based on the area of thermal radiation between July 2018 and December 2019. The relationship between local anesthesia mode and moderate or severe pain, and pain medications usage was assessed by using multivariable logistic regression models. RESULTS: A total of 243 consecutive patients were included in the study. Moderate or severe pain occurred in 84 of 124 (67.7%) patients with subpleural puncture point anesthesia and in 20 of 119 (16.8%) patients with subpleural anesthesia in the area of thermal radiation (p=.001). The intravenous pain medication was required in 56 of 124 (45.2%) patients with subpleural puncture point anesthesia and in 9 of 119 (7.6%) patients with subpleural multisite anesthesia based on the area of thermal radiation (p=.001). Local anesthesia methods (p = 0.001), pleura-to-lesion distance (p=.02) and tumor size (p=.015) were independent risk factors for developing moderate or severe pain. There were no differences in adverse events and local tumor progression rate. CONCLUSIONS: Subpleural multisite anesthesia based on the area of thermal radiation for peripheral lung malignancy MWA can result in lower intraprocedural pain compared with the subpleural puncture point anesthesia. Thus, a subpleural multisite anesthesia technique may be most helpful when performing MWA of peripheral malignancy in patients who are not sedated with general or intravenous anesthesia.

INTRODUCTION: The decrease in the postoperative recurrence rate after thoracoscopic bullectomy for spontaneous pneumothorax is an issue that should be tackled even at this moment. We presently make sure to do the reinforcement of the visceral pleura around between the staple line on bullectomy and the common sites of the new-born bullae such as apex, top site of S6, interlobar fissure to prevent postoperative recurrence. PURPOSE: We evaluated the latest efficacy of preventing postoperative recurrence by widely covering the staple line and the common sites of the new-born bullae with a polyglycolic acid( PGA) sheet after bullectomy. METHODS: Retrospective analyses were performed for 1,097 patients with spontaneous pneumothorax who received thoracoscopic bullectomy at our hospital between January 2011 and December 2020. The 1-year, 3-years, 5-years postoperative recurrence rates of 229 patients with spontaneous pneumothorax were respectively calculated with the Kaplan-Meier method. RESULTS: The 1-year, 3-years, 5-years postoperative recurrence rates of spontaneous pneumothorax were 0.9%, 3.6%, 4.0%, respectively. CONCLUSIONS: Combination treatment with bullectomy and wide coverage of the staple line and the common sites of the new-born bullae with the PGA sheet reduced satisfyingly postoperative recurrence rates of spontaneous pneumothorax.

PURPOSES: Here, we present the tips and pitfalls of video-assisted thoracoscopic( VATS) total pleural adhesiolysis( TPA), determined on an empirical basis. PATIENTS AND METHODS: From 2012 to 2020, VATS-TPA was performed in 33 patients undergoing pulmonary anatomic lung resection at our institute. The basic procedure was as follows:after peeling off the area of pleural adhesion surrounding the surgical ports using the fingers, the thoracoscope was inserted into the thorax and the adhesions in other areas were peeled off under thoracoscopic guidance. RESULTS: The adhesiolysis group had a longer operating time, greater blood loss, and higher rate of conversion to thoracotomy compared to the non-adhesiolysis group. However, the results were acceptable considering the extra manipulation for adhesiolysis. CONCLUSIONS: VATS-TPA is a necessary component of the standard surgical procedure for general thoracic surgeons in cases of total pleural adhesion.

The adhesion between the visceral and parietal pleura makes video-assisted thoracoscopic surgery (VATS) difficult or impossible. When performing VATS without conversion to thoracotomy due to pleural adhesion, it is important to( â °) evaluate the presence and extent of the adhesion preoperatively, (â ±) carefully perform detachment, and( â ²) adequately repair the injured visceral pleura. We evaluate visceral sliding with the help of chest ultrasonography and plan the best approach to make utility inci-sions, camera port, and third-port incisions. Considering the difficulty in repairing the injured visceral pleura under VATS, we perform extra-pleural detachment of adhesions around the injured visceral pleura, which can facilitate the repair of the pleural injury. For repairing pleural injury, we use free mediastinal fat tissue as biological pledgets to support suturing. In this report, we present the approaches and techniques we follow to perform VATS for patients with pleural adhesion.

Objective: To explore the efficacy and safety of position selection in combination with intra-pleural thrombin injection in the treatment of persistent air leakage (PAL) after medical thoracoscopic treatment of bullous pulmonary-pleural diseases (e.g. spontaneous pneumothorax or giant emphysematous bulla). Methods: This was a prospective study conducted in Rizhao Hospital of Traditional Chinese Medicine from August 2018 to November 2020. Twenty patients(19 males,1 female) with a mean age of (62.3±8.1) years met the diagnostic criteria for PAL which was defined as the air leak persisted more than 3 days despite of the closed thoracic drainage after medical thoracoscopic treatment of bullous pulmonary-pleural diseases.They received the following treatment procedures (referred to as "position plus"):â Pleural cavity injection (50% glucose 20 ml+thrombin 5 000 U).â¡Changing the patient's position under continuous negative pressure suction to find the position causing the complete stop or significant reduction of air leakage, and keeping in the position for 24-48 hours.â¢If the PAL wasn't stopped 48 hours later, the procedures above would be repeated.The duration of air leakage after "position plus", times of pleural cavity injection, condition of lung re-expansion, recurrence of air leakage and complications during hospitalization were recorded. Descriptive statistics were used to summarize the results:¯x±s or M(P25, P75) for continuous variables; frequency and percentages for categoric variables. Results: A total of 20 patients were included. The average duration of air leakage after"position plus" was (1.32±0.97) days. The times of pleural cavity injection required were 1.0(1.0, 1.0).All the patients showed good lung re-expansion in review of imaging after PAL was stopped. One patient had recurrent air leakage during hospitalization. No serious complications occurred. Conclusion: The comprehensive "position plus" intervention method is effective, safe and easily operating for the treatment of PAL after medical thoracoscopic treatment of bullous pulmonary-pleural diseases.

BACKGROUND: Severe congenital chylothorax (SCC) may result in respiratory failure, malnutrition, immunodeficiency, and sepsis. Although typically managed with bowel rest, parenteral nutrition, and octreotide, persistent chylothoraces require surgical management. At our institution, a pleurectomy, unilateral or bilateral, in combination with mechanical pleurodesis and thoracic duct ligation is performed for SCC, and we describe our approach and outcomes. MATERIALS AND METHODS: We reviewed over 15-year period neonatal patients with SCC managed surgically with pleurectomy after medical therapy was unsuccessful. Patients were divided into two groups: those who underwent pleurectomy within 28 d of diagnosis (early group) and those who underwent pleurectomy after 28 d (late group). Resolution of chylothorax was defined by the absence of clinical symptoms as well as absent or minimal pleural effusion on chest X-ray. RESULTS: Of 40 patients diagnosed with SCC over the study period, 15 underwent pleurectomy, eight early [mean time to operation = 20 (IQR 17, 23) d] and 7 late [59 (42, 75) d, P = 0.001]. Overall survival was 67% (10 of 15). Seven of 8 (88%) neonates who underwent early pleurectomy survived versus 3 of 7 (43%) who underwent late pleurectomy (P = 0.07). Length of stay was lower in the early group than the late group [73 (57, 79) versus 102 (109, 213) d, P = 0.05]. All patients who survived to discharge had resolution of their chylothorax. CONCLUSIONS: Pleurectomy with mechanical pleurodesis and thoracic duct ligation is effective in the management of severe congenital chylothorax. When performed earlier, pleurectomy for severe congenital chylothorax may be associated with improved survival and shorter hospital length of stay.

PURPOSE: Non-small cell lung cancer (NSCLC) involving the chest wall is usually treated with en bloc rib resection or parietal pleurectomy; however, the former causes chest wall deformity and the latter is associated with local recurrence. To prevent both these sequalae, we performed the "ribcage" procedure for tumors involving the chest wall after induction chemoradiotherapy. METHODS: This was a single center retrospective study conducted from 2012 to 2018. The "ribcage" procedure is designed to preserve the ribs of patients with lung tumors involving chest wall and involves peeling the intercostal muscles and periosteum from the ribs, resulting in a birdcage-like appearance. Seventeen patients with NSCLC clearly involving the chest wall, but not destroying the ribs, were treated with induction chemoradiotherapy, followed by the ribcage procedure. A negative margin at the ribs was confirmed by intraoperative frozen sections in 16 of these patients, who then underwent the ribcage procedure. RESULTS: Complete resection was achieved in all 16 patients, none of whom experienced major postoperative complications. After a median follow-up period of 37 months, there was no evidence of local recurrence in any of the patients. CONCLUSION: Our findings suggest that the ribcage procedure is the preferable surgical option as it can prevent chest wall deformities as well as local recurrence.

PURPOSE: To evaluate the clinical impact of pleurotomy during skeletonized internal thoracic artery (ITA) harvesting in patients undergoing on-pump coronary artery bypass grafting (CABG). METHODS: Consecutive patients (n = 758) who underwent CABG with skeletonized ITA were divided into 2 groups according to pleural integrity: open pleura (OP) and closed pleura (CP). Propensity score matching was performed after retrospective data extraction. The measured outcomes were postoperative pulmonary and hemorrhagic complications, 30-day mortality, and duration of hospital stay. RESULTS: Among 236 propensity score-matched pairs, there was no statistically significant difference between the 2 groups in terms of first 30-day mortality (OP, n = 7 [3%]; CP, n = 5 [2.5%]), blood product use (OP, 0.90 ± 0.71; CP, 0.74 ± 0.7), or median duration of hospital stay. The incidence of postoperative pleural effusion, thoracentesis, prolonged mechanical ventilation, respiratory failure, excessive drainage, cardiac tamponade, and reexploration and the number of patients requiring transfusion were similar in both groups. CONCLUSION: The clinical effect of pleural protection or pleurotomy on postoperative outcomes is limited in patients undergoing on-pump CABG with skeletonized ITA.
