Is surgical rib fixation in patients aged more than 65 years old associated with worse outcomes compared to younger patients? A retrospective single-center study.

BACKGROUND: There is no robust data regarding rib fixation in elderly patients. The aim of this study is to compare the postoperative outcomes of patients aged less and more than 65 years old. METHODS: Patients operated from January 2012 to December 2018 were retrospectively analyzed. The following data were collected: age, sex, comorbidities, smoking habit, Injury Severity Score (ISS), number of fractured ribs, indication for surgery, associated injuries, time from trauma to surgery, number of fixed ribs, intrathoracic injuries, duration of intubation, ICU stay, postoperative cardiopulmonary complications, blood transfusion, overall and 30-day mortality, length of stay. RESULTS: There was no difference regarding the ISS (p = 0.09), the number of rib fractures (p = 0.291), the indication for surgery, the number of fixed ribs (p = 0.819), the ICU stay (p = 0.096), the postoperative intubation duration (p = 0.059), the cardiopulmonary complications (p = 0.273) and perioperative blood transfusions (p = 0.34). Elderly patients presented more postoperative cognitive complications (p < 0.001). There was no difference in terms of overall mortality (p = 0.06) and 30-day mortality (p = 0.69). Elderly patients stayed longer in the hospital (p < 0.001). CONCLUSIONS: The outcomes of rib fixation in the elderly patients are comparable to younger patients. However, elderly patients experience more frequently postoperative cognitive complications and their hospitalizations are longer.

A Single-Center Experience of Osteosynthesis Material Infection after Rib Fixation for Blunt Trauma.

INTRODUCTION: There is no data regarding the incidence and treatment of deep infection affecting the surgical implants after rib fixation. The aim of this study is to share our experience in the management of infected material after surgical rib fixation. METHODS: The medical records of operated patients from January 2012 to December 2018 were retrospectively analyzed. RESULTS: Three patients out of 87 (3.44%) developed an infection. One patient was treated conservatively and two patients were operated for hardware removal. CONCLUSIONS: The lack of evidence prompts for the design of surgical databases to share experience and enhance available data.

Role of RAPID score and surgery in the management of pleural infection: a single center retrospective study.

Background: The RAPID [Renal (urea level), Age, Pleural fluid purulence, source of Infection and Denutrition (albumin level)] score classifies patients with pleural infection according to mortality risk at 3 months. This study aims to assess the applicability of this score in a thoracic surgery department and to determine the impact of surgery in the management of pleural infection depending on the Rapid score. Methods: In this single center retrospective study, patients managed for pleural infection, from January 1st 2013 to June 30th 2019, were included. The primary endpoint was the probability of survival at 6 months and 12 months depending on the RAPID score. Secondary endpoint was the probability of survival at 6 and 12 months in patients who had surgeries (surgical treatment group) and patients who didn't have surgery (medical treatment group). Results: Seventy-four patients were included, with a median age of 54.5 years. According to the RAPID score, the low-, medium- and high-risk groups had 30, 30 and 14 patients respectively. The probability of survival at 6 and 12 months in the low- and medium-risk groups were both 0.967 [95% confidence index (CI95): 0.905-1] whereas, the probabilities of survival at 6 and 12 months in the high-risk group was significantly lower at 0.571 (CI95: 0.363-0.899) and 0.357 (CI95: 0.177-0.721) respectively (P<0.0001). The probabilities of survival at 6 months and 12 months in the medical treatment group was 0.875 (CI95: 0.786-0.974) and 0.812 (CI95: 0.704-0.931) respectively compared to the surgical treatment group where probabilities of survival at 6 and 12 months were both 0.923 (CI95: 0.826-1) (P=0.26). Conclusions: In our study, patients with pleural infection, classified as high-risk according to the RAPID score, had a lower survival rate compared to low- and medium-risk patients. No difference in survival rate was found between patients classified as low- and medium-risk. In selected patients, surgical management seems to decrease mortality compared to exclusive medical management: this result should be confirmed in larger prospective studies.

Artificial intelligence in thoracic surgery: past, present, perspective and limits.

Artificial intelligence (AI) technology is becoming prevalent in many areas of everyday life. The healthcare industry is concerned by it even though its widespread use is still limited. Thoracic surgeons should be aware of the new opportunities that could affect their daily practice, by direct use of AI technology or indirect use via related medical fields (radiology, pathology and respiratory medicine). The objective of this article is to review applications of AI related to thoracic surgery and discuss the limits of its application in the European Union. Key aspects of AI will be developed through clinical pathways, beginning with diagnostics for lung cancer, a prognostic-aided programme for decision making, then robotic surgery, and finishing with the limitations of AI, the legal and ethical issues relevant to medicine. It is important for physicians and surgeons to have a basic knowledge of AI to understand how it impacts healthcare, and to consider ways in which they may interact with this technology. Indeed, synergy across related medical specialties and synergistic relationships between machines and surgeons will likely accelerate the capabilities of AI in augmenting surgical care.

Three Hundred Fifty-One Patients With Pneumothorax Undergoing Uniportal (Single Port) Video-Assisted Thoracic Surgery.

BACKGROUND: Video-assisted thoracic surgery (VATS) is usually performed using three ports. Uniportal VATS has not yet been widely developed. We report our single institution experience in uniportal VATS for the surgical management of 351 patients with pneumothorax. METHODS: Between November 2009 and February 2016, we conducted a study in 351 patients treated for pneumothorax using uniportal VATS. Resection of apical bullae associated with partial pleurectomy, pleural abrasion, or talc effusion was performed. RESULTS: The mean age was 29.6 ± 10.1 years. Surgical indications were mainly persistence or recurrence of pneumothorax. Sixty-seven patients (19%) presented with complications. At the 30-day control, 60.1% of patients were asymptomatic; 85% of patients were satisfied with the single small scar. The recurrence rate was 3.6% at 24 ± 13 months. CONCLUSIONS: Uniportal VATS is feasible, safe, and reproducible in the treatment of pneumothorax. Morbidity is similar to multiport VATS. The recurrence rate is comparable with best results after multiport VATS or thoracotomy. Patients were satisfied with the single small scar.

Cervical and retrosternal approach to the left thoracic cavity using a flexible endoscope.

OBJECTIVES: Mediastinoscopy remains the gold standard for surgical exploration of the mediastinum. The use of this approach to access the left thoracic cavity could be complicated by vascular or neurological lesion. The aim of this experimental work was to describe a new approach to the left thoracic cavity through a cervical incision and retrosternal space using a flexible endoscope as a unique instrument. METHODS: We conducted an experimental work on 12 refrigerated and non-embalmed cadavers. Through a cervical incision, we dissected the retrosternal space to the level of Louis angle and then opened the left mediastinal pleura. We introduced the flexible endoscope through this pleural window into the left thoracic cavity. We defined three distances between the borders of the endoscope entry point, the phrenic nerve and the mammary artery: Distance 1: between the medial edge of the endoscope entrance point and the medial edge of the left mammary artery, Distance 2: between the top of the endoscope entrance point and the penetration of phrenic nerve in the left thoracic cavity and Distance 3: between the lateral edge of the entrance point of the endoscope and the medial edge of the phrenic nerve. To measure these distances, we performed a left postero-lateral thoracotomy. RESULTS: Procedure was successfully executed in 10 of the 12 studied subjects. The mean distances 1, 2 and 3 were 17.1 (range 2-40), 39.5 (17-80) and 19.1 mm (10-40), respectively. The minimal Distance 1 was in two subjects 0.2 and 0.5 mm. CONCLUSIONS: This approach avoids the para-aortic and supra-aortic zone; this access could be less dangerous than already described access techniques. Despite the limits of our work on cadavers, and the two failures in the application of the access, the mean distances we calculated show the potential safety of our approach concerning the phrenic nerve and the mammary artery. An experimental protocol on living animals is currently underway with the aim of confirming the safety of our approach.
