Anterior chest wall resection and sternal body wedge for primary chest wall tumour: reconstruction technique with biological meshes and titanium plates.

Chest wall tumours are heterogeneous neoplasms, either primary or metastatic, with a malignancy rate of 50%. Surgical resection is one of the mainstays of the treatment, however, chest wall resections can be particularly challenging depending onto the resection size, site and patient habitus. The surgical strategy should be carefully analysed preoperatively, keeping in mind the need of an oncological radical resection (R0) in accordance to the reconstruction principles elicited by le Roux and Sherma since 1983, which include restoring the chest wall rigidity, preserving pulmonary mechanics, protect the intrathoracic organs, avoiding paradox movements of the chest cavity and, possibly, to reduce the thoracic deformity. In this context, we herewith report our surgical reconstruction technique following an anterior chest wall resection and sternal body wedge for a primary chest wall tumour (chondrosarcoma).

Low Accuracy of Computed Tomography and Positron Emission Tomography to Detect Lung and Lymph Node Metastases of Colorectal Cancer.

BACKGROUND: Minimally invasive surgery, stereotactic radiotherapy, and radiofrequency ablation are commonly proposed in the case of pulmonary colorectal-metastasis as alternatives to conventional open surgery. Preoperative imaging assessment by computed tomography (CT) scan and fluorodeoxyglucose positron emission tomography (FDG-PET) are critical to guide oncologic radical treatment. Our aim was to investigate the accuracy of CT and FDG-PET for the evaluation of the number of pulmonary colorectal metastases and thoracic lymph nodal involvement (LNI). METHODS: Patients who underwent lung surgical resection for pulmonary colorectal metastases from 2004 to 2014 were analyzed. Concordance between histology, CT scan, and FDG-PET findings were assessed. RESULTS: Data of 521 patients were analyzed. Of those, FDG-PET was performed in 435 (83.5%). A moderate agreement between both CT scan (kappa index: 0.42) and FDG-PET (kappa index: 0.42) findings and the histologically proven number of metastases was observed. The number of histologically proven metastases was correctly discriminated in 61.7% of cases with CT scan and in 61.8% of cases with FDG-PET. Multiple metastases were discovered in 20.9% of clinical single metastasis cases with CT scan, and in 24.4% of those cases with FDG-PET. One hundred fifty patients (29.1%) presented with pathologic LNI. A poor agreement was observed between LNI and CT scan findings (kappa index: 0.02), and a weak agreement was observed concerning LNI and FDG-PET findings (kappa index: 0.39). CONCLUSIONS: Computed tomography and FDG-PET have limitations if the objective is to detect all malignant nodules and to discriminate the LNI in cases of pulmonary metastases of colorectal cancer.

Digital versus traditional air leak evaluation after elective pulmonary resection: a prospective and comparative mono-institutional study.

BACKGROUND: The increased demand to reduce costs and hospitalization in general pushed several institution worldwide to develop fast-tracking protocols after pulmonary resections. One of the commonest causes of protracted hospital stay remains prolonged air leaks (ALs). We reviewed our clinical practice with the aim to compare traditional vs. digital chest drainages in order to evaluate which is the more effective to correctly manage the chest tube after pulmonary resection. METHODS: All patients submitted to elective pulmonary resection for lung malignancies, between April to December, 2014 in our General Thoracic Surgery Department were included in the study. The primary outcome was the chest tube duration, the secondary the postoperative overall hospitalization. Significant differences between traditional and digital groups were investigated with logistic regression models. Numerical variables between the groups were compared by means of the unpaired Wilcoxon-Mann-Whitney test. RESULTS: Both series of patients were comparable for clinical, surgical and pathological characteristics. Chest tube duration showed to be significantly shorter in the digital group (3 vs. 5 days, P=0.0009), while the hospitalization was longer in traditional one [8 vs. 7 days in digital drainage (DD); P=0.0385]. No chest drainage replacement was required at 30-day, in both groups. CONCLUSIONS: We were able to demonstrate that patients managed with a digital system experienced a shorter chest tube duration as well as a lower overall hospital length of stay, compared to those who received the traditional drainage (TD).
