Thoracotomy is a major cause of respiratory impairment, increasing the risk of postoperative pulmonary complications (PPC). Systems assessing ribcage kinematics may detect changes in chest expansion following thoracotomy and may thus aid in the development of patient-tailored chest physiotherapy. Hence, we aimed to identify studies assessing changes in chest wall movement following thoracotomy using objective measures. The Cochrane library, MEDLINE, EMBASE, Scopus and Web of Science databases were searched to find relevant articles providing an objective assessment of chest wall movement following thoracotomy. Methodological quality of included studies concerning chest wall movement following thoracotomy was assessed by use of QUADAS-2 tool. A total of 12 articles were included for the assessment of chest wall changes following thoracotomy using objective measures. Four studies measured changes in the cross-sectional area of the ribcage and abdomen using the respiratory inductive plethysmography (RIP), 1 study computed the chest wall compliance by monitoring the intra-pleural pressure, 3 studies measured changes in chest circumference with a simple tape measure and 4 articles performed a compartmental analysis of the chest wall volume by means of an optoelectronic plethysmography (OEP). There was no delay in the collection of data of the index test and reference standard, resulting in a low risk of bias for the flow and timing domain. Across all studies, participants underwent the same reference standard, resulting in a low risk of verification bias. Several objective measures were able to detect changes in chest wall displacement following thoracotomy and differed in the practical use and invasive nature. OEP allows a compartmental analysis of the chest wall volume. Hence, this system allows to assess chest wall movement changes following thoracotomy and the impact of different types of surgical approach. Furthermore, it could aid in the development of tailored physiotherapy.

A 44-year-old man with a history of facioscapulohumeral muscular dystrophy and pectus excavatum presented with multiyear history of progressive, severe respiratory dysfunction, pain, recurrent respiratory infection, and chest wall deformity. With bioprosthetic engineers, the surgical team customized a 3-dimensional printed model of a sternal implant interacting with the patient's anatomy. After approval from the Food and Drug Administration, the customized sternal plates were created and implanted in a sternal reconstruction operation.

Understanding the Mechanisms of Main Bronchial Compression in Patients with Intracardiac Anomalies.

Ann Thorac Surg Short Rep

September 2024

Department of Pediatric Cardiovascular Surgery, Kanazawa Medical University, Ishikawaken, Japan.

Background: The study focuses on vascular compression of the main bronchus in the aortopulmonary space, examining potential contributors within the same axial plane. Its goal is to uncover mechanisms of bronchial compression in patients with intracardiac anomalies and review surgical outcomes, aiming to enhance future results.

Methods: The morphology and topology of structures within the axial plane of the aortopulmonary space were objectively analyzed, including the sternum, ascending aorta, heart, pulmonary artery, descending aorta, and other relevant elements.

Background: Pectus excavatum (PE) is the most common congenital chest wall defect and is characterized by the inward displacement of the sternum and costal cartilages. To date, there are limited data on adult patients undergoing the Nuss procedure for PE. This study aimed to assess the complication rate between the pediatric and adult populations and assess the trends in demographics.

Background: With advancements in minimally invasive thoracic surgery techniques, such as video-assisted thoracoscopic surgery and robotic surgery, the design of vascular staplers has evolved to meet the requirements of these procedures. Consequently, newer generations of automatic staplers with improved handling and reduced size have been introduced, such as two-row staplers, which are more maneuverable and less bulky than their three-row counterparts.

Case Presentation: A 68-year-old man with lung cancer underwent a right middle and lower lobectomy due to tumor invasion into the central middle bronchial trunk, rendering the preservation of the middle lobe impossible.

Biomedical Engineering Department, Faculty of Engineering, Helwan University, Cairo, Egypt.

Car accidents, infections caused by bacteria or viruses, metastatic lesions, tumors, and malignancies are the most frequent causes of chest wall damage, leading to the removal of the affected area. After excision, artificial bone or synthetic materials are used in chest wall reconstruction to restore the skeletal structure of the chest. Chest implants have traditionally been made from metallic materials like titanium alloys due to their biocompatibility and durability.
