Thoracoscopic treatment of pulmonary sequestration

Objective: Pulmonary sequestration is a rare congenital malformation and may be the cause of recurrent infections or hemoptysis. It has been shown in case reports that resection by video-assisted thoracic surgery (VATS) is feasible despite the possible technical difficulties due to inflammatory changes, but its role has not been evaluated yet in a larger series of consecutively treated patients. Methods: Retrospective analysis of all consecutively thoracoscopically treated patients (between January 1991 and January 2005) with pulmonary sequestration in a single center. We included 14 patients in the study who fulfilled the criteria; seven were women. Median age was 33 years (20-64 years). The following data were analyzed for all patients: major symptoms, diagnostic procedures, treatment, and outcome. Operative parameters and findings including operating time, blood loss, anatomical location of the sequestration, and feeding vessels were evaluated. Results: Leading symptoms were recurrent infections (10), hemoptysis (3), and chest discomfort (1). The diagnosis was made by CT scan. Additionally, an arteriography or an angio-MRI was done in three patients and one patient, respectively. Thirteen intralobar (all lower lobes, eight on the right) and one left-sided extralobar pulmonary sequestration were resected. We performed eight lobectomies, four atypical segmentectomies, one extralobar resection, and one occlusion of the aberrant artery. One case had to be converted to a thoracotomy due to bleeding from the aberrant artery. There was no mortality. Complications included pneumonia in three cases, one hemothorax, one pneumothorax after removing the chest tube, and one wound infection. All were treated conservatively. Conclusion: Thoracoscopic treatment of pulmonary sequestration is feasible in experienced hands. The aberrant systemic artery can be freed and dissected safely despite the frequently occurring inflammatory changes. Conversion rate to thoracotomy is lo

Thoracic Outlet Syndrome: Single Center Experience on Robotic Assisted First Rib Resection and Literature Review.

Background Thoracic outlet syndrome (TOS) is a pathological condition caused by a narrowing between the clavicle and first rib leading to a compression of the neurovascular bundle to the upper extremity. The incidence of TOS is probably nowadays underestimated because the diagnosis could be very challenging without a thorough clinical examination along with appropriate clinical testing. Beside traditional supra-, infraclavicular or transaxillary approaches, the robotic assisted first rib resection has been gaining importance in the last few years. Methods We conducted a retrospective cohort analysis of all patients who underwent robotic assisted first rib resection due to TOS at Lucerne Cantonal Hospital and then we performed a narrative review of the English literature using PubMed, Cochrane Database of Systematic Reviews and Scopus. Results Between June 2020 and November 2021, eleven robotic assisted first rib resections were performed due to TOS at Lucerne Cantonal Hospital. Median length of stay was 2 days (Standard Deviation: +/- 0.67 days). Median surgery time was 180 min (Standard Deviation: +/- 36.5). No intra-operative complications were reported. Conclusions Robotic assisted first rib resection could represent a safe and feasible option in expert hands for the treatment of thoracic outlet syndrome

Candida Albicans Osteomyelitis after Chest Wall Blunt Trauma: A Case Report

Fungal osteomyelitis is a rare disease that can occur in immunocompromised patients. We report a case of a patient with a primary rib osteomyelitis after a blunt trauma of the chest wall. Aggressive surgical debridement along with antifungal therapy was the cornerstone of the disease management in this patient

Thoracic outlet syndrome: a retrospective analysis of robotic assisted first rib resections.

Thoracic Outlet Syndrome (TOS) is caused by compression of the neurovascular bundle between the first rib and the clavicula, which can cause a large panel of symptoms and has a reported incidence of approximately 2-4/100.000. Surgical treatment consists of the resection of the first rib and is historically performed using an open, mainly transaxillary, approach. Recent developments resulted in a minimally invasive approach using Robotic Assisted Thoracic Surgery (RATS). With this study, the investigators want to provide a descriptive study of first rib resection using RATS approach at two different centers. We reviewed the files of 47 patients affected by TOS and who benefited from first rib resection using RATS approach between 2016 and 2021. Patient characteristics as well as Length of Stay (LOS), affected side, operative time (OT), complications, etiology, VAS score and post-operative QOL were gathered in the database. Statistical analysis was performed using IBM SPSS statistics 25 ®. Results were reported in mean and standard deviation. 47 patients affected by TOS received first rib resection using robotic approach. Mean age was 47 ± 12 yrs. 16 patients were operated on the left side and 31 on the right side. All the patients reported complete resolution of symptoms. At 1-year follow-up, no patient suffered from recurrence. There were no intraoperative complications. Postoperative complications occurred in two patients, one patient developed pneumothorax after chest tube removal and one patient developed recurrent pleural effusion which required surgery. Mean LOS was 3 ± 1 days and mean OT was 122 ± 40 min. First rib resection performed using a RATS approach is a safe technique with excellent outcomes and which is beneficial for the patient in terms of LOS, pain and symptom resolution

Airway complications after lung transplantation : risk factors, prevention and outcome

PURPOSE: Anastomotic complications following lung transplantation (LuTx) have been described in up to 15% of patients. Challenging to treat, they are associated with high morbidity and a mortality rate of 2-5%. The aim of this study was to analyze the incidence of complications in a consecutive series of bronchial anastomosis after LuTx at our center and to delineate the potential risk factors. METHODS: Between 1992 and 2007, 441 bronchial anastomoses were performed in 235 patients. Indications for transplantation were cystic fibrosis (35.7%) emphysema (28.1%) pulmonary fibrosis (12.8%) and pulmonary hypertension (7.7%). There were 206 sequential bilateral and 28 single transplants including lobar engraftments in 20 cases. The donor bronchus was shortened to the plane of the lobar carina including the medial wall of the intermediate bronchus. Peribronchial tissue was left untouched. Anastomosis was carried out using a continuous absorbable running suture (PDS 4/0) at the membranous and interrupted sutures at the cartilaginous part. Six elective surveillance bronchoscopies were done monthly during the first half-year post-LuTx, with detailed assessment of the pre- and post-anastomotic airways. RESULTS: One-year survival since 2000 was 90.5%. In all 441 anastomoses performed, no significant dehiscence was observed. In one patient, a small fistula was detected and closed surgically on postoperative day five. Fungal membranes were found in 50% of the anastomoses at 1 month and in 14% at 6 months. Discrete narrowing of the anastomotic lumen without need for intervention was found in 4.9% of patients at 1 month and in 2.4% at 6 months. Age, cytomegalovirus status, induction therapy, immunosuppressive regimen, ischemic time, and ventilation time had no influence on bronchial healing. CONCLUSIONS: Clinically relevant bronchial anastomotic complications after LuTx can be avoided by use of a simple standardized surgical technique. Aggressive antibiotic and antifungal therapy might play an important supportive role

Pneumonectomy for lung cancer in the elderly: lessons learned from a multicenter study.

Background 60% of patients diagnosed with lung cancer are older than 65 years and are at risk for substandard treatment due to a reluctance to recommend surgery. Pneumonectomy remains a high risk procedure especially in elderly patients. Nevertheless, the impact of age and neoadjuvant treatment on outcomes after pneumonectomy is still not well described. Methods We performed a multicentric retrospective study, analyzing outcomes of patients older than 70 years who underwent pneumonectomy for central primary lung malignancy between January 2009 and June 2019 in 7 thoracic surgery departments: Lucerne and Bern (Switzerland), Hamilton (Canada), Alicante (Spain), Monza (Italy), London (UK), Leuven (Belgium). Survival was estimated with Kaplan-Meier, and differences in survival were determined by log-rank analysis. We investigated pre- and post-operative prognostic factors using Cox proportional hazards regression model; multivariable analysis was performed only with variables, which were statistically significant at the invariable analysis. Results A total of 136 patients were included in the study. Mean age was 73.8 years (SD 3.6). 24 patients (17.6%) had an induction treatment (chemotherapy alone in 15 patients and chemo-radiation in 9). Mean length of stay (LOS) was 12.6 days (SD 10.39) and 74 patients (54.4%) had experienced a post-operative complication: 29 (21.3%) had a pulmonary complication, 33 (24.3%) had a cardiac complication and in 12 cases (8.8%) patients experienced both cardiac and pulmonary complications. 16 patients were readmitted [median LOS 13.7 days (range, 2-39 days)] and of those 14 (10.3%) required redo surgery. Median overall survival (OS) of the entire cohort was 38 months (95% CI: 29.9-46.1 months); in-hospital mortality was 1.5%, 30-day mortality rate was 3.7%, while 90-day mortality was 8.8% accounting for 5 and 12 patients respectively. Patients receiving neo-adjuvant therapy did not experience a higher incidence of postoperative complications (P=0.633), did not have a longer postoperative course (P=0.588), nor did they have an increased mortality rate (P=0.863). Conclusions Age should not be considered an absolute contraindication for pneumonectomy in elderly patients even after neoadjuvant treatment. It has become apparent that especially in these patients, a patient-tailored approach with a careful selection should be used to define the risk-benefit balance

Thymic tumours: a single center surgical experience and literature review on the current diagnosis and management of thymic malignancies.

Objective This study aimed to provide an extensive overview of clinical and pathological findings along with various therapeutic options analyzing in addiction, retrospectively, the surgical outcomes of a single center cohort. Background Thymic neoplasms are rare thoracic tumors which commonly are located in the anterior mediastinum and are associated with a wide spectrum of clinical presentations. They may run an indolent course or could present a very aggressive biologic progression with infiltration of mediastinal structures and presence of distant metastases. The pathogenesis of these tumors is so far not completely clear. Several treatment modalities in a multidisciplinary setting have to be considered in order to provide the best treatment for patients affected by thymic tumors. Methods We conducted a retrospective cohort analysis of all patients who underwent surgery due to thymic tumor in a university hospital located in Switzerland (Bern University Hospital) and then we performed a narrative review of the English literature using PubMed, Embase, Cochrane Database of Systematic Reviews and Scopus. Conclusions Minimally invasive techniques play an important role in the treatment of thymic tumors. A careful patients selection in a multidisciplinary setting is mandatory in order to offer the best treatment for patients affected by thymic tumors

Accelerated treatment of postpneumonectomy empyema: a binational long-term study

OBJECTIVE: Postpneumonectomy empyema remains a clinical challenge. We proposed an accelerated therapy without an open chest window 5 years ago. This concept was evaluated on a larger scale in 2 centers in 2 different countries. METHODS: Between July 1995 and October 2005, 75 consecutive patients with postpneumonectomy empyema were treated in Szczecin, Poland (n = 35), and Zurich, Switzerland (n = 40). The therapy consisted of repeated open surgical debridement of the pleural cavity after achievement of general anesthesia, a negative pressure wound therapy of the temporarily closed chest cavity filled with povidone-iodine-soaked towels, and continuous suction and systemic antimicrobial therapy. If present, bronchopleural fistulae were closed and reinforced either with a muscle flap or the omentum. Finally, the pleural space was filled with an antibiotic solution and definitively closed. RESULTS: Of 75 patients (63 men; median age, 59 years; age range, 19-82 years), postpneumonectomy empyema was present on the right in 46 patients (32 with bronchopleural fistula) and in 29 patients (12 with bronchopleural fistula) on the left. Median time between pneumonectomy and postpneumonectomy empyema was 131 days (range, 7-7200 days). Bronchopleural fistulae have been closed and additionally reinforced by means of different methods (omentum, 18; muscle, 11; pericardial fat, 5; azygos vein, 1). The chest was definitively closed within 8 days in 94.6% of patients. The median hospitalization time was 18 days (range, 9-134 days). Postpneumonectomy empyema was successfully treated in 97.3% of patients, including 10 (13%) patients who needed a second treatment cycle. Three (4%) patients died within 90 days. The median follow-up time was 29.5 moths (range, 3-107 months). CONCLUSIONS: Treatment of postpneumonectomy empyema with the accelerated treatment is effective and safe. Our results are superior compared with those in reported series using a (temporary) chest fenestration. Patients appreciate the physical integrity of the chest
