When size matters: changing opinion in the management of pleural space-the rise of small-bore pleural catheters

Tube thoracostomy is usually the first step to treat several thoracic/pleural conditions such as pneumothorax, pleural effusions, haemothorax, haemo-pneumothorax and empyema. Today, a wide range of drains is available, ranging from small to large bore ones. Indications for an appropriate selection remains yet matter of debate, especially regarding the use of small bore catheters. Through this paper, we aimed to retrace the improvements of drains through the years and to review the current clinical indications for chest drain placement in pleural/thoracic diseases, comparing the effectiveness of small-bore drains vs. large-bore ones

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)

Proctor-guided virtual reality-enhanced three-dimensional video-assisted thoracic surgery: an excellent tutoring model for lung segmentectomy

OBJECTIVE: Lung segmentectomy using video-assisted thoracoscopic surgery (VATS) is an effective strategy to treat early-stage lung cancer. The objective of this case report is to show the efficacy of Hyper Accuracy 3D (HA3D) reconstruction as a tool for trainee surgeons and expert surgeons to perform complex procedures.METHODS: An 84-year-old man was treated for colon-rectal cancer. During follow-up, a pulmonary nodule on the right anterior upper lobe suspected for intestinal metastasis was revealed by a computed tomography scan. According to functional tests and radiology, a right anterior upper lobe segmentectomy was planned. HA3D lung reconstruction was used during surgery.RESULTS: Using the HA3D virtual model, the procedure was performed with healthy tissue sparing, ensuring safe resection margins. No postoperative morbidities were noted. The patient referred good pain control. The hospital stay was 6 days.CONCLUSIONS: VATS segmentectomy is a technically demanding procedure. HA3D lung reconstruction can help surgeons effectively perform the resection, aiding at individuating intersegmental planes, bronchi, and vessels, guaranteeing oncologic radicality and safe surgical margins, and preserving respiratory function

Validation of EORTC and CALGB prognostic models in surgical patients submitted to diagnostic, palliative or curative surgery for malignant pleural mesothelioma

BACKGROUND: To assess the trend of our surgical patients affected by malignant pleural mesothelioma (MPM) and submitted to diagnostic/palliative or curative surgical procedures and to validate the European Organisation for Research and Treatment of Cancer (EORTC) prognostic score in our patient population. METHODS: This is a cohort study of patients submitted to surgery for MPM from January 2007 to December 2013. Primary outcome was overall survival (OS). Univariate and multivariate-adjusted comparisons by EORTC prognostic score for OS were accomplished using Cox method. Adjusted models included the following clinical variables: kind of procedure, smoking habit, asbestos exposure, Charlson’s Comorbidity Index (CCI), clinical tumor stage, adjuvant chemotherapy, dyspnoea, chest pain and haematological variables according to the score features. Nomenclature of the surgical procedures matches the International Association for the Study Lung Cancer (IASLC)/International Mesothelioma Interest Group (iMIG). RESULTS: One-hundred sixty-six consecutive cases were collected: the median age at surgery was 73 years and 123 patients (75%) had a history of asbestos exposure. Ninty patients (54%) were submitted to a palliative/diagnostic thoracoscopy, 30 to pleurectomy/decortication (P/D), and 6 to extra-pleural pneumonectomy (EPP). Clinical TNM stages were as follows: 99 (60%) stage I–II, 34 (20%) stage III and 33 (20%) stage IV. The median follow-up (FU) was 19 months [interquartile range (IQR), 9–31 months] and the FU-completeness was 98%. By the end of the study 130 patients died (78%). One- and 3-year OS was 60% and 36%, respectively. Patients submitted to EPP and P/D showed a better survival (P=0.013). Multivariable model showed an independent prognostic value of EORTC score (HR =2.86, P<0.001). CONCLUSIONS: In selected patients, aggressive surgical approaches, although not radical, may still be beneficial. The EORTC prognostic index proved to be an independent prognostic factor in our cohort of patients and therefore is a reliable and valid instrument that may be implemented in the daily practice

Awake or intubated surgery in diagnosis of interstitial lung diseases? A prospective study

BACKGROUND: Risks associated with video-assisted surgical lung biopsy (VASLB) for interstitial lung disease (ILD) with endotracheal intubation and mechanical ventilation are not nil. Awake video-assisted surgical lung biopsy (Awake-VASLB) has been proposed as a method to obtain a precise diagnosis in several different thoracic diseases. OBJECTIVES: To compare clinical outcomes of Awake-VASLB and Intubated-VASLB in patients with suspected ILDs. METHODS: From June 2016 to February 2020, all patients submitted to elective VASLB for suspected ILD were included. Differences in outcomes between Awake-VASLB and Intubated-VASLB were assessed through univariable, multivariable-adjusted, and a propensity score-matched analysis. RESULTS: Awake-VASLB was performed in 66 out of 100 patients, while 34 underwent Intubated-VASLB. The Awake-VASLB resulted in a lower post-operative morbidity (OR 0.025; 95% CI 0.001–0.35; p=0.006), less unexpected intensive care unit admission, less need for rescue therapy for pain, a reduced surgical and anaesthesiologic time, a reduced chest drain duration, and a lower post-operative length of stay. CONCLUSION: Awake-VASLB in patients affected by ILD is feasible and seems safer than Intubated-VASLB
