Multicentre retrospective analysis on pulmonary metastasectomy: an European perspective.

OBJECTIVES: To assess the current practice of pulmonary metastasectomy at 15 European Centres. Short- and long-term outcomes were analysed. METHODS: Retrospective analysis on patients ≥18 years who underwent curative-intent pulmonary metastasectomy (January 2010 to December 2018). Data were collected on a purpose-built database (REDCap). Exclusion criteria were: previous lung/extrapulmonary metastasectomy, pneumonectomy, non-curative intent and evidence of extrapulmonary recurrence at the time of lung surgery. RESULTS: A total of 1647 patients [mean age 59.5 (standard deviation; SD = 13.1) years; 56.8% males] were included. The most common primary tumour was colorectal adenocarcinoma. The mean disease-free interval was 3.4 (SD = 3.9) years. Relevant comorbidities were observed in 53.8% patients, with a higher prevalence of metabolic disorders (32.3%). Video-assisted thoracic surgery was the chosen approach in 54.9% cases. Wedge resections were the most common operation (67.1%). Lymph node dissection was carried out in 41.4% cases. The median number of resected lesions was 1 (interquartile range 25-75% = 1-2), ranging from 1 to 57. The mean size of the metastases was 18.2 (SD = 14.1) mm, with a mean negative resection margin of 8.9 (SD = 9.4) mm. A R0 resection of all lung metastases was achieved in 95.7% cases. Thirty-day postoperative morbidity was 14.5%, with the most frequent complication being respiratory failure (5.6%). Thirty-day mortality was 0.4%. Five-year overall survival and recurrence-free survival were 62.0% and 29.6%, respectively. CONCLUSIONS: Pulmonary metastasectomy is a low-risk procedure that provides satisfactory oncological outcomes and patient survival. Further research should aim at clarifying the many controversial aspects of its daily clinical practice.

A Word of Caution for Gossypiboma.

Gossypiboma, a retained nonabsorbable surgical sponge, is a major safety issue despite being infrequent, causing serious malpractice debates. In addition to this, it may mimic a range different disease within the thorax and even have unpleasant clinical presentations even after years.In this article, we report four gossypiboma cases with nonspecific clinical presentations to emphasize the importance of keeping this diagnosis in mind with all patients who have had a previous operation.

Pectus cross bars increase hospital readmission rates due to serous pleural effusion.

OBJECTIVE: Pectus Excavatum's (PE) surgical treatment should be patient specific. In this article, we aimed to compare parallel and cross bar variations of the Nuss method and analyze if there is any difference in results. METHODS: In this study, a total of 891 patients treated with the Nuss method between August 2005 and February 2018 were considered. These were retrieved from a prospectively recorded PE database. Of these, 276 double-bar patients were included in the study. Patients with parallel bars (225 cases) and patients with crossed bars (51 cases) were compared in terms of age, gender, symmetry, family history, additional anomalies, mean operation time, postoperative hospital stay (days) and hospital readmission rate. RESULTS: The mean age was measured at 20.7 for parallel bar patients and 20.1 for crossed bars patients. There was no statistically significant difference in terms of age, gender, and mean operation time between two groups. On the other hand, statistical significance was found between two groups when analyzing the deformities' symmetry, patients' family history and additional anomalies. The statistically significant difference of postoperative hospital stay between two groups is clinically negligible. Postoperative hospital readmission rates due to serous pleural effusion were found to be significantly increased in patients with crossed bars (p < 0.001). CONCLUSION: While pleural effusion requiring readmission was statistically more frequent in cross bars, in centers where thoracentesis can be managed, Nuss method can still be applied safely, even in cases with difficult, complex deformities. LEVEL OF EVIDENCE: III. Treatment study.

Minimally Invasive Repair of Pectus Carinatum.

BACKGROUND: The second most common deformity of the anterior chest wall, pectus carinatum, is a diverse deformity that has been largely managed using open techniques. This study reviews clinical experience with a newly designed bar for minimally invasive repair of pectus carinatum. METHODS: We reviewed the records of all patients recorded in our Chest Wall Deformities Clinical Database. Between January 2006 and November 2016, minimally invasive repair of pectus carinatum was performed in 172 patients. All met the criteria of a "compression test" of 10 to 25 kg/cm2. The mean age was 17.3 years, and 22.7% had a positive family history of a congenital chest wall deformity. Symmetric and asymmetric deformities were treated. During our study period, we designed 4 different bar configurations and their related stabilizers. All patients are assessed every 3 to 6 months. After 2 to 3 years of follow-up, the bar and the stabilizers are removed. RESULTS: Of 172 patients, 97.1% tolerated the procedure very well. The operation was a mean length 76.6 minutes. Average blood loss was 40 mL. Mean hospital length of stay was 3.7 days. Complications included pneumothorax, wire breakdown/rib cut, wound infection, severe pain, skin hyperpigmentation, nickel allergy, and overcorrection leading to excavatum. Patients returned to routine activity in 10 to 14 days. With a mean follow-up of 29.8 months in bar removal patients, 130 of 172 (93.8%) reported excellent results. CONCLUSIONS: Minimally invasive repair of pectus carinatum with the technically modified fourth-generation bar and its securing system has advantages of low morbidity, short hospital stay, and excellent cosmetic results, even in asymmetric cases.
