Intestinal tuberculosis versus Inflammatory Bowel Diseases: a never-ending challenge.

Inflammatory Bowel Diseases (IBD) and intestinal tuberculosis (ITB) frequently share similar clinical, radiological, endoscopic and histologic features. The misdiagnosis of IBD can lead to worsening of ITB course, eventually with dissemination of Mycobacterium tuberculosis (MTB) due to immunosuppressive treatment. We herein report a challenging diagnosis of ITB, progressed from localized to disseminated, in a pregnant woman previously misdiagnosed with Crohn' disease (CD) on prolonged steroid treatment. Furthermore, we focus on three main issues: 1) the need for tuberculosis (TB) screening in pregnant women and in patients coming from TB endemic countries; 2) the effect of prolonged steroid treatment in misdiagnosed TB, particularly on its histological pattern; 3) the optimum clinical management of ITB.

Management of COVID-19-related post-intubation tracheal stenosis.

Introduction: The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic has affected Italy since the beginning of 2020. Endotracheal intubation, prolonged mechanical ventilation, and tracheostomy are frequently required in patients with severe COVID-19. Tracheal stenosis is a potentially severe condition that can occur as a complication after intubation. The aim of this study was to evaluate the utility and safety of endoscopic and surgical techniques in the treatment of tracheal stenosis related to COVID-19. Materials and Methods: Between June 2020 and May 2022, consecutive patients with tracheal stenosis who were admitted to our surgical department were considered eligible for participation in the study. Results: A total of 13 patients were included in the study. They consisted of nine women (69%) and four men (31%) with a median age of 57.2 years. We included seven patients with post-tracheostomy tracheal stenosis. Bronchoscopy was performed to identify the type, location, and severity of the stenosis. All patients underwent bronchoscopic dilation and surveillance bronchoscopy at 7 and 30 days after the procedure. We repeated endoscopic treatment in eight patients. Three patients underwent tracheal resection anastomosis. Final follow-up bronchoscopy demonstrated no residual stenosis. Conclusions: The incidence of and risk factors associated with tracheal stenosis in critically ill patients with COVID-19 are currently unknown. Our experience confirms the efficacy and safety of endoscopic management followed by surgical procedures in cases of relapsed tracheal stenosis.

Diagnostic accuracy of endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA) for mediastinal lymph node staging of lung cancer.

Lung cancer is one of the leading causes of cancer-related mortality around the world. A prompt diagnosis and accurate staging are of the essence in order to establish the appropriate treatment plan. Mediastinal lymph nodes involvement is the most important parameter to define the therapeutic path, and particularly to decide whether a patient can be offered a potentially curative surgery. Endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA), together with oesophageal ultrasound (EUS), has a pivotal role in the diagnosis and staging of lung cancer. These procedures have excellent diagnostic performances, can be performed without requiring general anaesthesia, and are far less invasive than mediastinoscopy and video-assisted thoracic surgery (VATS). Moreover, EBUS-TBNA allows to biopsy intrapulmonary lymph nodes. Different studies have been investigated the diagnostic accuracy of EBUS-TBNA for the diagnosis and staging of lung cancer, with always good but heterogeneous results. In some studies, EBUS-TBNA has shown to yield adequate samples for molecular testing and immunocytochemistry too. Rapid on site cytologic evaluation (ROSE) can be used to assess the adequacy of samples during the endoscopic procedure. The aim of this review article is to describe the current evidence on the diagnostic accuracy of EBUS-TBNA for the diagnosis of lung cancer. We also reported our centre's experience and the results of 456 EBUS-TBNA performed between April 2016 and March 2020.

Prophylactic continuous positive airway pressure after pulmonary lobectomy: a randomized controlled trial.

BACKGROUND: Despite advances in perioperative care and surgical techniques, patients undergoing pulmonary lobectomy are still at high risk for postoperative complications. Among interventions expected to reduce complications, continuous positive airway pressure (CPAP) is a discussed option. This trial aims to test the hypothesis whether prophylactic application of CPAP following pulmonary lobectomy can reduce postoperative complications. METHODS: The study was designed as a prospective, randomized, controlled trial. Patients with clinical stage I non-small cell lung cancer scheduled for pulmonary lobectomy were eligible and were trained for the use of CPAP interface. The control group received standard postoperative pain management and physiotherapy; in addition, the study group received CPAP (PEEP 8-12 cmH2O, 2 hours thrice daily for three days). RESULTS: After the appropriate selection, 163 patients were considered for the analysis: 82 patients constituted the control group, 81 the study group. The two groups were substantially comparable for preoperative parameters. The rate of postoperative complications was lower in the study group (24.7% vs. 43.9%; P=0.015) as well as the hospital stay (6 vs. 7 days; P=0.031). The stepwise logistic regression model identified: CPAP [odd ratio (OR): 0.3026, CI: 0.1389-0.6591], smoke habits [OR: 2.5835, confidence interval (CI): 1.0331-6.4610] and length of surgery in minutes (OR: 1.0102, CI: 1.0042-1.0163) as regressors on postoperative complications. CONCLUSIONS: The present trial demonstrated that prophylactic application of CPAP during the postoperative period after pulmonary lobectomy for stage I non-small cell lung cancer was effective in prevent postoperative complications.
