The role of repairing lung lacerations during video-assisted thoracoscopic surgery evacuations for retained haemothorax caused by blunt chest trauma

Surgical stabilization of rib fractures (SSRF): the WSES and CWIS position paper

BACKGROUND

Rib fractures are one of the most common traumatic injuries and may result in significant morbidity and mortality. Despite growing evidence, technological advances and increasing acceptance, surgical stabilization of rib fractures (SSRF) remains not uniformly considered in trauma centers. Indications, contraindications, appropriate timing, surgical approaches and utilized implants are part of an ongoing debate. The present position paper, which is endorsed by the World Society of Emergency Surgery (WSES), and supported by the Chest Wall Injury Society, aims to provide a review of the literature investigating the use of SSRF in rib fracture management to develop graded position statements, providing an updated guide and reference for SSRF.

METHODS

This position paper was developed according to the WSES methodology. A steering committee performed the literature review and drafted the position paper. An international panel of experts then critically revised the manuscript and discussed it in detail, to develop a consensus on the position statements.

RESULTS

A total of 287 studies (systematic reviews, randomized clinical trial, prospective and retrospective comparative studies, case series, original articles) have been selected from an initial pool of 9928 studies. Thirty-nine graded position statements were put forward to address eight crucial aspects of SSRF: surgical indications, contraindications, optimal timing of surgery, preoperative imaging evaluation, rib fracture sites for surgical fixation, management of concurrent thoracic injuries, surgical approach, stabilization methods and material selection.

CONCLUSION

This consensus document addresses the key focus questions on surgical treatment of rib fractures. The expert recommendations clarify current evidences on SSRF indications, timing, operative planning, approaches and techniques, with the aim to guide clinicians in optimizing the management of rib fractures, to improve patient outcomes and direct future research.

The role of video-assisted thoracoscopy in chest trauma: a retrospective monocentric experience

Video-assisted thoracoscopy (VAT) plays an essential role in the exploration of pleural cavity after thoracic trauma, although some doubts about the precise and specific indications persist. This study examines the eligibility criteria for videothoracoscopy and establishes the ideal timing for VAT. Between January 2011 and November 2022, we observed 923 polytraumatized patients. All patients underwent computed tomography (CT) scan total body with and without contrast enhancement. Two hundred and nine patients carried out VAT within 10 ± 2 h of injury while 8 patients after 20 ± 1 h. The Injury Severity Score (ISS) was 31 ± 1 and the Glasgow Coma Scale was 14.1 ± 0.3 upon arrival at the hospital. One hundred and nineteen patients displayed hemothorax (55%), 62 hemopneumothorax (28.5%), 21 penetrating wound (9.6%), 10 pneumothorax (4.6%) and 5 chylothorax (2.3%). In 18 patients (8.3%) without vascular, diaphragmatic, or parenchymal lesion the treatment consisted in chest tube placement. VAT was converted to video-assisted thoracoscopic surgery (VATS) in 190 patients (87.5%), to open surgery in 8 (3.7%) and to laparoscopy in 1 (0.5%). Twelve patients (5.5%) with diaphragm ruptures < 5 cm in diameter were treated by separate stitches suture in VATS. Only eight postoperative complications (4 pneumonia, three atelectasis and one pulmonary embolism) out of 217 VAT, positively resolved with medical treatment, were noted exclusively in patients undergoing minimally invasive approach 20 ± 1 h after trauma. Early VAT in selected patients is a safe and easy procedure that ensure a quick diagnosis of lesions and an accurate management of the most thoracic injuries among trauma patients. The prompt identification of injuries, to avoid life-threatening conditions requiring rapid intervention, responds to medico-legal needs to which VAT fulfills.

Delayed hemothorax following blunt thoracic trauma: a case report

BACKGROUND

Late hemothorax is a rare complication of blunt chest trauma. The longest reported time interval between the traumatic event and the development of hemothorax is 44 days.

CASE PRESENTATION

An elderly patient with right-sided rib fractures from chest trauma, managed initially with closed thoracostomy, presented with a delayed hemothorax that occurred 60 days after initial management, necessitating conservative and then surgical intervention due to the patient's frail condition and associated complications.

CONCLUSIONS

This case emphasizes the clinical challenge and significance of delayed hemothorax in chest trauma, highlighting the need for vigilance and potential surgical correction in complex presentations, especially in the elderly.

Traumatic lung laceration secondary to avulsed lung adhesion - A case report

Background

Pulmonary lacerations caused by an avulsion force on an adhesion between the lung and chest wall following blunt thoracic injury are very rare. They may result in pneumothorax and/or hemothorax and may not be immediately apparent clinically or radiologically.

Case presentation

We present the case of a healthy 34-year-old male who sustained blunt thoracic injury. He was clinically stable, and his initial routine images were unremarkable. The patient was discharged home on the same day. He presented a week later with a massive hemothorax requiring surgical intervention which revealed bleeding from an avulsed adhesion between the lung and chest wall. Bleeding was successfully controlled by hemostatic agent, and the patient had an uneventful recovery.

Conclusion

Hemothorax requiring intervention from an avulsed adhesion may occur following blunt thoracic trauma. Initial imaging and clinical finding may be misleading. Close follow up and adequate patient education should be ensured prior to discharge following seemingly trivial trauma.

[VATS in Thorax Trauma]

Since the early 1990s, video-assisted thoracoscopy (VATS) has been increasingly established for a variety of indications in the treatment of patients with thoracic trauma. During this time, one premise for the use of thoracoscopy has not changed. Its use is consistently recommended only for trauma patients with stable circulation and respiration. To define the indications of VATS for use in thoracic trauma, the Pulmonary Injury Group - as part of the Working Committee for Thoracic Trauma of the German Society for Thoracic Surgery (DGT) and the German Society for Trauma Surgery (DGU) - has developed treatment recommendations based on a current literature review (based on the PRISMA Checklist/here: MEDLINE via PubMed from 1993 to 2022). In the present study, after reviewing the available literature, the indications for VATS in the care of thoracic trauma were identified, in order to formulate clinical recommendations for the use of VATS in thoracic trauma. The analysis of 1679 references identified a total of 4 randomised controlled trials (RCTs), 4 clinical trials, and 5 meta-analyses or systematic reviews and 39 reviews, which do not allow a higher level of recommendation than consensual recommendations, due to the low evidence of the available literature. Over the past 30 years, stabilisation options in the care of trauma patients have improved significantly, allowing expansion of indications for the use of VATS. Moreover, the recommendation for more than 50 years to thoracotomise trauma patients in case of an initial blood loss ≥ 1500 ml via the inserted chest drainage or in case of continuous blood loss ≥ 250 ml/h over 4 h is now only relative with today's better stabilisation measures. For unstable/non-stabilisable patients with a thoracic injury requiring emergency treatment, thoracotomy remains the method of choice, while VATS is recommended for a wide range of indications in the diagnosis and treatment of stable patients with a penetrating or blunt thoracic trauma. The indications for VATS are persistent haemothorax, treatment of injuries and haemorrhages to the lung, diaphragm, thoracic wall and other organ injuries, and in the secondary phase, treatment of thoracic sequelae of injury (empyema, persistent pulmonary fistula, infected atelectasis, etc.).

Management of thoracic trauma

Managing major thoracic trauma begins with identifying and anticipating injuries associated with the mechanism of injury. The key aims are to reduce early mortality and the impact of associated complications to expedite recovery and restore the patient to their pre-injury state. While imaging is imperative to identify the extent of thoracic trauma, some pathology may require immediate treatment. The majority can be managed with adequate pleural drainage, but respiratory failure and poor gas exchange may require either non-invasive or invasive ventilation. Ventilation strategies to protect from complications such as barotrauma, volutrauma and ventilator-induced lung injury are important to consider. The management of pain is vital in reducing respiratory complications. A multimodal strategy using local, regional and systemic analgesia may mitigate respiratory side effects of opioid use. With optimal pain management, physiotherapy can be fully utilised to reduce respiratory complications and enhance early recovery. Thoracic surgeons should be consulted early for consideration of surgical management of specific injuries. With a greater understanding of the mechanisms of injury and the appropriate use of available resources, favourable outcomes can be reached in this cohort of patients. Overall, a multidisciplinary and holistic approach results in the best patient outcomes.

It is Time to Replace Large Drains with Small Ones After Fixation of Rib Fractures: A Prospective Observational Study

Introduction

Large-bore chest tubes are usually applied after thoracic surgery. Recently, small-bore tubes have been increasingly considered owing to the extensive use of video-assisted thoracoscopic surgery (VATS). This study assessed the differences in outcomes between large-bore and small-caliber drainage tubes in patients undergoing surgical stabilization of rib fractures (SSRF) with VATS.

Methods

Overall, 131 patients undergoing SSRF with VATS were prospectively enrolled, including 65 patients receiving 32-Fr chest tubes (group 1) and 66 patients receiving 14-Fr pigtail catheters (group 2) for postoperative drainage. The clinical characteristics and perioperative outcomes of the patients were compared.

Results

All patients underwent SSRF with VATS within 4 days after trauma. After the operation, the mean duration of chest tubes was longer than that of pigtail catheters, with statistical significance (5.08 ± 2.47 vs 3.11 ± 1.31, P = 0.001). Length of stay (LOS) was also longer in group 1 (10.38 ± 2.90 vs 8.18 ± 2.44, P = 0.001). After multivariate logistic regression, the only independent factors between the two groups were duration of postoperative drainage (adjusted odds ratio [AOR] 1.746; 95% confidence interval [CI] 0.171–10.583, P = 0.001) and hospital LOS (AOR 1.272; 95% CI 0.109–4.888, P = 0.027).

Conclusion

After reconstruction of the chest wall and lung parenchyma, small-caliber drainage catheters could be easily and safely applied to reduce hospital LOS.

Missed injuries in trauma patients: the value of a diagnostic thoracotomy or thoracoscopy during surgical stabilisation of rib fractures

PURPOSE

Over the last decade Surgical Stabilisation of Rib Fractures (SSFR) gained popularity in our hospital. With increased numbers, we noted that frequently injuries were missed during primary/secondary survey and radiological imaging that were found during the surgical procedure. With this observation, the research question was formulated: What is the value of diagnostics thoracotomy or thoracoscopy during surgical stabilisation of rib fractures?

METHODS

In a single-centre, retrospective study between February 2010 and December 2019, trauma patients who underwent Surgical Stabilisation of Rib Fractures (SSFR) and an inspection thoracotomy were included. All radiological injuries were compared with intraoperative findings. Missed injuries that were discovered during the surgical procedure that were not analysed during primary/secondary survey or on radiological imaging were recorded and retrospectively analysed by an independent radiologist.

RESULTS

Fifty-one patients were included. Eight patients had additional injuries; all had a diaphragmatic rupture, one patient had an additional stomach laceration, and another patient had a significant lung laceration in need of surgical repair. On a CT scan there are 7 signs of predictive value for a diaphragmatic rupture. Only 13 out of the total of 56 diaphragm rupture CT signs were confirmed on the primary CT scans of the eight patients with diaphragmatic injuries; therefore, still 77% of signs could not be confirmed by initial radiological findings.

CONCLUSION

With the recent shift towards surgical stabilisation of rib fractures, an inspection thoracoscopy or thoracotomy during SSFR should be considered to minimise the incidence of missed intrathoracic injuries requiring early or late surgical treatment.

Assessing the analgesic efficacy of oral epigallocatechin-3-gallate on epidural catheter analgesia in patients after surgical stabilisation of multiple rib fractures: a prospective double-blind, placebo-controlled clinical trial

CONTEXT

Thoracic trauma results in multiple rib fractures (MRF), and surgical stabilisation of rib fractures (SSRF) can relieve fracture pain. Epigallocatechin-3-gallate (EGCG) is reported to exhibit beneficial effects in bone-related metabolic and differentiation processes.

OBJECTIVE

To study the clinical effect of EGCG on regional analgesia for pain relief in MRF patients after SSRF.

MATERIALS AND METHODS

Ninety-seven MRF patients (61 males, 36 females) who were on epidural catheter analgesia after SSRF were recruited. They were randomly divided into: oral EGCG 100 mg (oral grade) twice daily for 10 days and placebo groups. Pain scores, incentive spirometry (IS) volumes, respiratory rate and oxygen saturation (SpO₂) were assessed day 10 after SSRF.

RESULTS

Comparing results from the placebo and EGCG group, in the 10-day intervention course, oral EGCG reduced pain score (8 at base line vs. 4 at end of intervention in EGCG group, p < 0.05; 4 in EGCG group vs. 6 in placebo group at end of intervention, p < 0.05), improved IS volume (713 at base line vs. 1072 at end of intervention in EGCG group, p < 0.05; 1072 in EGCG group vs. 953 in placebo group at end of intervention, p < 0.05) and respiratory rate (24 at base line vs. 15 at end of intervention in EGCG group, p < 0.05; 15 in EGCG group vs. 19 in placebo group at end of intervention, p < 0.05). However, no further enhancing effect on SpO₂ was observed in the EGCG group (0.98 in EGCG group vs. 0.98 in placebo group at end of intervention, p > 0.05).

DISCUSSION AND CONCLUSIONS

Although the study is limited by a relatively small sample size and lack of serum factor analysis, the key results and the study design, for the first time, nevertheless pave the way for trials with larger number of patients to understand the effect of EGCG in MRF patients that are undergoing SSRF.

Does routine uniportal thoracoscopy during rib fixation identify more injuries and impact outcomes?

Background

Flail chest and severely displaced rib fractures due to blunt trauma can be associated with intrathoracic injuries. At our institution, two thoracic surgeons perform all surgical stabilization of rib fractures (SSRF): one performs routine uniportal thoracoscopy (R-VATS) at the time of SSRF and the other for only select cases (S-VATS). In this pilot study, we hypothesized that R-VATS at the time of SSRF identifies and addresses intrathoracic injuries not seen on imaging and may impact patient outcomes.

Methods

A retrospective review of all patients who underwent SSRF from 2013–2019 at our institution was performed for severely displaced rib fractures or flail chest. Data collected included demographics, imaging results, treatment strategy, and operative findings.

Results

Ninety-nine patients underwent SSRF. Uniportal thoracoscopy was performed on 69% of these patients. When thoracoscopy was performed, 31 additional injuries were identified. R-VATS identified 23 additional intrathoracic findings at time of thoracoscopy not seen on CT scan compared to 8 findings in the S-VATS group (P=0.367). At 3 months follow-up, one empyema and one diaphragmatic hernia required reoperation—neither of which underwent thoracoscopy at time of SSRF. There were no differences in LOS, operative times, and overall mortality between the SSRF/thoracoscopy and SSRF only groups.

Conclusions

R-VATS at the time of SSRF did not identify a statistically significant greater number of occult intrathoracic injuries compared to S-VATS. R-VATS was not associated with increased operative time, LOS, and mortality. Further study is needed to determine if there is benefit to R-VATS in patients meeting requirements for rib fracture repair.

Clinical efficacy of surgical versus conservative treatment for multiple rib fractures: A meta-analysis of randomized controlled trials

BACKGROUND

There are still controversies between surgical treatment and conservative treatment for multiple rib fractures (MRFs). No consensus has been reached concerning the indications and timing of surgery. In this meta-analysis, we aimed to determine the optimal treatment for MRFs.

METHODS

Six databases (PubMed, Medline, Embase, Cochrane, Cnki, Wanfang Database) were retrieved for all eligible randomized controlled trials (RCTs) published before January 2020. MRFs were treated either with operative reduction and internal fixation or conservative treatment. The pertinent data were retrieved. The quality of RCTs was evaluated by the modified Jadad rating scale and meta-analysis was performed using RevMan 5.3 software.

RESULTS

Seven RCTs involving 538 MRFs patients (260 were treated surgically vs. 278 conservatively) were included in this meta-analysis. Compared with conservative treatment, surgical treatment resulted in shorter length of hospital stay (WMD -8.48; 95% CI -11.34 to -5.63; P < 0.001), length of ICU stay (WMD -5.72; 95% CI -7.31 to -4.13; P < 0.001) and duration of mechanical ventilation (WMD -4.93; 95% CI -8.79 to -1.07; P = 0.01), with a lower risk of complications including pneumonia (RR 0.40; 95% CI 0.30 to 0.53; P < 0.001) and chest wall deformity (RR 0.07; 95% CI 0.03 to 0.14; P < 0.001). The sensitivity analysis carried out by excluding one study with significant heterogeneity showed that the rate of tracheostomy was lower in the surgical group than in the conservative group (RR 0.44; 95% CI 0.28 to 0.71; P = 0.0008).

CONCLUSIONS

For patients with MRFs, surgical treatment resulted in faster recovery, a lower risk of complications and better prognosis than conservative treatment.

Blunt trauma related chest wall and pulmonary injuries: An overview

Physical traumas are tragic and multifaceted injuries that suddenly threaten life. Although it is the third most common cause of death in all age groups, one out of four trauma patients die due to thoracic injury or its complications. Blunt injuries constitute the majority of chest trauma. This indicates the importance of chest trauma among all traumas. Blunt chest trauma is usually caused by motor vehicle accident, falling from height, blunt instrument injury and physical assault. As a result of chest trauma, many injuries may occur, such as pulmonary injuries, and these require urgent intervention. Chest wall and pulmonary injuries range from rib fractures to flail chest, pneumothorax to hemothorax and pulmonary contusion to tracheobronchial injuries. Following these injuries, patients may present with a simple dyspnea or even respiratory arrest. For such patient, it is important to understand the treatment logic and to take a multidisciplinary approach to treat the pulmonary and chest wall injuries. This is because only 10% of thoracic trauma patients require surgical operation and the remaining 90% can be treated with simple methods such as appropriate airway, oxygen support, maneuvers, volume support and tube thoracostomy. Adequate pain control in chest trauma is sometimes the most basic and best treatment. With definite diagnosis, the morbidity and mortality can be significantly reduced by simple treatment methods.

Facilitating ventilator weaning through rib fixation combined with video-assisted thoracoscopic surgery in severe blunt chest injury with acute respiratory failure

Background

Severe blunt chest injury sometimes induces acute respiratory failure (ARF), requiring ventilator use. We aimed to evaluate the effect of performing rib fixation with the addition of video-assisted thoracoscopic surgery (VATS) on patients with ARF caused by blunt thoracic injury with ventilator dependence.

Methods

This observational study prospectively enrolled patients with multiple bicortical rib fractures with hemothorax caused by severe blunt chest trauma. All patients received positive pressure mechanical ventilation within 24 h after trauma because of ARF. Some patients who received rib fixation with VATS were enrolled as group 1, and the others who received only VATS were designated as group 2. The length of ventilator use was the primary clinical outcome. Rates of pneumonia and length of hospital stay constituted secondary outcomes.

Results

A total of 61 patients were included in this study. The basic demographic characteristics between the two groups exhibited no statistical differences. All patients received operations within 6 days after trauma. The length of ventilator use was shorter in group 1 (3.19 ± 3.37 days vs. 8.05 ± 8.23, P = 0.002). The rate of pneumonia was higher in group 2 (38.1% vs. 75.0%, P = 0.005). The length of hospital stay was much shorter in group 1 (17.76 ± 8.38 days vs. 24.13 ± 9.80, P = 0.011).

Conclusion

Rib fixation combined with VATS could shorten the length of ventilator use and reduce the pneumonia rate in patients with severe chest blunt injury with ARF. Therefore, this operation could shorten the overall length of hospital stay.

Hemothorax: A Review of the Literature

Hemothorax is a collection of blood in the pleural cavity usually from traumatic injury. Chest X-ray has historically been the imaging modality of choice upon arrival to the hospital. The sensitivity and specificity of point-of-care ultrasound, specifically through the Extended Focal Assessment with Sonography in Trauma (eFAST) protocol has been significant enough to warrant inclusion in most Level 1 trauma centers as an adjunct to radiographs.^1,2 If the size or severity of a hemothorax warrants intervention, tube thoracostomy has been and still remains the treatment of choice. Most cases of hemothorax will resolve with tube thoracostomy. If residual blood remains within the pleural cavity after tube thoracostomy, it is then considered to be a retained hemothorax, with significant risks for developing late complications such as empyema and fibrothorax. Once late complications occur, morbidity and mortality increase dramatically and the only definitive treatment is surgery. In order to avoid surgery, research has been focused on removing a retained hemothorax before it progresses pathologically. The most promising therapy consists of fibrinolytics which are infused into the pleural space, disrupting the hemothorax, allowing for further drainage. While significant progress has been made, additional trials are needed to further define the dosing and pharmacokinetics of fibrinolytics in this setting. If medical therapy and early procedures fail to resolve the retained hemothorax, surgery is usually indicated. Surgery historically consisted solely of thoracotomy, but has been largely replaced in non-emergent situations by video-assisted thoracoscopy (VATS), a minimally invasive technique that shows considerable improvement in the patients' recovery and pain post-operatively. Should all prior attempts to resolve the hemothorax fail, then open thoracotomy may be indicated.

A new instrument for surgical stabilization of multiple rib fractures

Objective

Rib fixation is an effective treatment for patients with multiple rib fractures. We retrospectively evaluated the application of a four-claw titanium plate in patients with rib fractures.

Methods

Fifty-four patients treated for multiple rib fractures in our hospital from 2012 to 2016 were divided into a surgery group (n = 27) and conservative treatment group (n = 27). The patients’ age, sex, cause of fracture, Injury Severity Score, chest Abbreviated Injury Scale score, number of ventilator days, and length of hospitalization were recorded.

Results

The mean duration of mechanical ventilation was 4.5 ± 0.7 and 7.9 ± 1.7 days in the surgery and control group, respectively, with a significant difference. The length of intensive care unit stay was also significantly different between the groups (5.9 ± 0.6 vs. 10.6 ± 1.9 days, respectively). The length of hospital stay and recovery time to regular life in the surgery and control group were 11.5 ± 1.9 and 3.9 ± 4.0 days and 38.2 ± 8.3 and 60.8 ± 12.1 days, respectively, both with significant differences.

Conclusion

A four-claw titanium plate is valuable for patients with multiple rib fractures, allowing easy fixation of broken ribs beneath the scapula, even the second rib.

Diagnosis and management of a trapped lung or diaphragm by fractured ribs: analysis of patients undergoing rib fracture repair

BACKGROUND

There are few reports regarding a lung or diaphragm trapped by a fractured rib. This study aimed to describe the clinical presentations, diagnosis, and management of these intrathoracic pathologies.

METHODS

We retrospectively reviewed the database at our institute for patients with rib fractures who underwent thoracoscope-assisted surgical stabilization of rib fracture (SSRF). We analyzed the demographic data, mechanism of trauma, presentations, operative findings, and subsequent management strategies.

RESULTS

A total of 38 consecutive patients who underwent SSRF were analyzed. Three patients had a trapped lung and one had a trapped diaphragm. Abnormal radiographic findings were observed in 50% of cases. The median waiting time for surgery was 25 days. Surgery was indicated for intractable dynamic pain following conservative treatment. A definitive diagnosis was made during thoracoscopic exploration. Thoracoscopic repair and resection were used for trapped lungs and thoracoscopic release for a trapped diaphragm. We subsequently performed SSRF for unhealed rib fractures.

CONCLUSION

As per our analysis, the incidence of a trapped lung or diaphragm was 10.5%. If a patient presents with persistent intractable dynamic pain, thoracoscopic exploration with concurrent SSRF may be a feasible and effective treatment option.

Video-assisted thoracoscopic surgery in trauma: pros and cons

Thoracic injuries account for 60% of all trauma presentations. These patients often have extra-thoracic injuries adding to the complexity of their management. Morbidity and the associated mortality are significantly increased in the elderly. The majority of cases will comprise of simple rib fractures, requiring adequate analgesia. In those that require surgical intervention, the use of video-assisted thoracoscopic surgery (VATS) is becoming increasingly more popular. VATS can often provide greater visualisation of the intra-thoracic structures, whilst limiting the burden of injury to smaller non-rib spreading incisions. It is therefore becoming increasingly used as a diagnostic tool to identify the extend of the injuries whilst also allowing for therapeutic intervention. These benefits translate into decreased rate of post-operative complications and a shorter length of inpatient stay. We also discuss the relative contra-indications and cautions to the use of VATS in the setting of trauma.

Completely thoracoscopic surgical stabilization of rib fractures: can it be done and is it worth it?

Surgical stabilization of rib fractures (SSRF) is now a common operation at most high-volume trauma centers. Increased experience with the procedure has spawned a variety of technical modifications to minimize incision length, muscle division, scapular retraction, and general tissue trauma. The ultimate example of such a minimally invasive approach is completely thoracoscopic SSRF, which refers to using a video-assisted thoracoscopic surgery (VATS) technique to both reduce and fixate rib fractures in an intra-thoracic fashion. The benefits of thoracoscopic SSRF may be divided broadly into those that relate to the repair of the rib fractures themselves, and those that relate to adjuncts to rib fracture repair. With respect to the former, theoretical benefits include improved visualization of rib fractures (particularly in posterior and sub-scapular locations), minimization of trauma to overlying muscles and nerves, minimization of trauma to intra-thoracic structures, and elimination of palpable plates. With respect to the latter, theoretical advantages include evacuation of retained hemothorax, guided placement of loco-regional anesthesia and chest tubes, and identification and repair of associated, intra-thoracic injuries. A VATS may also aid in trainee education. Despite these theoretical benefits, early attempts at thoracoscopic SSRF have been limited by both user inexperience and inadequate instrumentation. Furthermore, there are currently no data comparing the efficacy of completely thoracoscopic SSRF to either contemporary, minimally-invasive, extra-thoracic SSRF or non-operative management.

Early versus late surgical stabilization of severe rib fractures in patients with respiratory failure: A retrospective study

Introduction

The timing of surgical stabilization of rib fractures remains controversial. We hypothesized that early surgical stabilization (within 3 days of injury) can improve clinical outcome in patients with severe rib fractures and respiratory failure. The aim of this study was to analyze the impact of early surgical stabilization of rib fractures on the perioperative results, clinical outcomes, and medical costs of patients with severe rib fractures and respiratory failure.

Methods

This was a retrospective comparative study based on a prospectively collected database at a single institute. Patients with severe rib fractures and respiratory failure who underwent surgical stabilization were classified into early (within 3 days of injury) and late (more than 3 days after injury) groups. Outcome measures included operation time, duration of mechanical ventilation, intensive care unit stay, hospital stay, complication rate, mortality rate, and medical cost.

Results

A total of 33 patients were enrolled (16 and 17 in the early and late groups, respectively). The demographics, trauma mechanism, associated injuries, and severity of trauma were comparable in both groups. The early group had significantly shorter duration of mechanical ventilation (median 36 vs. 90 hours, p = 0.03), intensive care unit stay (median 123 vs. 230 hours, p = 0.004), and hospital stay (median 12 vs. 18 days, p = 0.005); and lower National Health Insurance costs (median 6,617 vs. 10,017 US dollars, p = 0.031). The early group tended to have lower rates of morbidity and mortality, but the difference was not statistically significant.

Conclusion

Early surgical stabilization of rib fractures in selected patients may significantly shorten their duration of mechanical ventilation, and intensive care unit and hospital stays, while incurring less medical costs.

[Chest trauma from a surgical perspective]

Patients with multiple injuries in particular frequently also suffer from chest trauma. During the initial phase the identification and treatment of life-threatening injuries is essential and tension pneumothorax is of particular importance during this phase. The Advanced Trauma Life Support (ATLS) algorithm should be followed for structured treatment. In most cases treatment by insertion of a chest tube is sufficient but for some injuries an emergency thoracotomy is unavoidable as a life-saving intervention. In the further treatment especially a flail chest and retained hemothorax are responsible for complications, such as acute lung failure and thoracic empyema. Early operative interventions in the sense of rib fracture stabilization and thoracoscopy-assisted evacuation of hematomas can help to prevent such complications.

Thoracic irrigation prevents retained hemothorax: A prospective propensity scored analysis

BACKGROUND

Thoracic trauma resulting in hemothorax (HTx) is typically managed with thoracostomy tube (TT) placement; however, up to 20% of patients develop retained HTx which may necessitate further intervention for definitive management. Although optimal management of retained HTx has been extensively researched, little is known about prevention of this complication. We hypothesized that thoracic irrigation at the time of TT placement would significantly decrease the rate of retained HTx necessitating secondary intervention.

METHODS

A prospective, comparative study of patients with traumatic HTx who underwent bedside TT placement was conducted. The control group consisted of patients who underwent standard TT placement, whereas the irrigation group underwent standard TT placement with immediate irrigation using 1 L of warmed sterile 0.9% saline. Patients who underwent emergency thoracotomy, those with TTs removed within 24 hours, or those who died within 30 days of discharge were excluded. The primary end point was secondary intervention defined by additional TT placement or operative management for retained HTx. A propensity-matched analysis was performed with scores estimated using a logistic regression model based on age, sex, mechanism of injury, Abbreviated Injury Scale chest score, and TT size.

RESULTS

In over a 30-month period, a total of 296 patients underwent TT placement for the management of traumatic HTx. Patients were predominantly male (79.6%) at a median age of 40 years and were evenly split between blunt (48.8%) and penetrating (51.2%) mechanisms. Sixty (20%) patients underwent thoracic irrigation at time of initial TT placement. The secondary intervention rate was significantly lower within the study group (5.6% vs. 21.8%; OR, 0.16; p < 0.001). No significant differences in TT duration, ventilator days, or length of stay were noted between the irrigation and control cohort.

CONCLUSION

Thoracic irrigation at the time of initial TT placement for traumatic HTx significantly reduced the need for secondary intervention for retained HTx.

Bedside pleuroscopy in Taiwan : a great vision for critically-ill patients and intensivists

Bedside pleuroscopy can be used in daily practice by medical pulmonologists if a patient cannot tolerate either general anesthesia or being moved to an operating or endoscopy room due to their critical condition. It is a simple and safe technique that rarely has complications. The aim of this review is to summarize recent literatures about bedside pleuroscopy and share our experiences with using it in Taiwan.

Efficiency Analysis of Direct Video-Assisted Thoracoscopic Surgery in Elderly Patients with Blunt Traumatic Hemothorax without an Initial Thoracostomy

Hemothorax is common in elderly patients following blunt chest trauma. Traditionally, tube thoracostomy is the first choice for managing this complication. The goal of this study was to determine the benefits of this approach in elderly patients with and without an initial tube thoracostomy. Seventy-eight patients aged >65 years with blunt chest trauma and stable vital signs were included. All of them had more than 300 mL of hemothorax, indicating that a tube thoracostomy was necessary. The basic demographic data and clinical outcomes of patients with hemothorax who underwent direct video-assisted thoracoscopic surgery without a tube thoracostomy were compared with those who received an initial tube thoracostomy. Patients who did not receive a thoracostomy had lower posttrauma infection rates (28.6% versus 56.3%, P = 0.061) and a significantly shorter length of stay in the intensive care unit (3.13 versus 8.27, P = 0.029) and in the hospital (15.93 versus 23.17, P = 0.01) compared with those who received a thoracostomy. The clinical outcomes in the patients who received direct VATS were more favorable compared with those of the patients who did not receive direct VATS.

Thoracic irrigation prevents retained hemothorax: a pilot study

BACKGROUND

Upward of 20% of patients undergoing thoracostomy tube (TT) placement develop retained hemothorax (HTx) requiring secondary intervention. The aim of this study was to define the rate of secondary intervention in patients undergoing prophylactic thoracic irrigation.

METHODS

A prospective observational trial of 20 patients who underwent thoracic irrigation at the time of TT placement was conducted. Patients with HTx identified on chest x-ray were included. After standard placement of a 36-French TT, the HTx was evacuated using a sterile suction catheter advanced within the TT. Warmed sterile saline was instilled into the chest through the TT followed by suction catheter evacuation. The TT was connected to the sterile drainage atrium and suction applied. TTs were managed in accordance with our standard division protocol.

RESULTS

The population was predominantly (70%) male at median age 35 years, median ISS 13, with 55% suffering penetrating trauma. Thirteen (65%) patients underwent TT placement within 6 h of trauma with the remainder within 24 h. Nineteen patients received the full 1000-mL irrigation. The majority demonstrated significant improvement on postprocedure chest x-ray. The secondary intervention rate was 5%. A single patient required VATS on post-trauma day zero for retained HTx. Median TT duration was 5 d with median length of stay of 7 d. No adverse events related to the pleural lavage were noted.

CONCLUSIONS

Thoracic irrigation at the time of TT placement for traumatic HTx may decrease the rate of retained HTx.

Video-assisted thoracoscopic surgery for retained hemothorax in blunt chest trauma

Purpose of review

In the last decade, video-assisted thoracoscopic surgery (VATS) has become a popular method in diagnosis and treatment of acute chest injuries. Except for patients with unstable vital signs who require larger surgical incisions to check bleeding, this endoscopic surgery could be employed in the majority of thoracic injury patients with stable vital signs.

Recent findings

In the past, VATS was used to evacuate traumatic-retained hemothorax. Recent study has revealed further that lung repair during VATS could decrease complications after trauma. Management of fractured ribs could also be assisted by VATS. Early VATS intervention within 7 days after injury can decrease the rate of posttraumatic infection and length of hospital stay. In studies of the pathophysiology of animal models, N-acetylcysteine and methylene blue were used in animals with blunt chest trauma and found to improve clinical outcomes.

Summary

Retained hemothorax derived from blunt chest trauma should be managed carefully and rapidly. Early VATS intervention is a well tolerated and reliable procedure that can be applied to manage this complication cost effectively.

A case of delayed hemothorax with an inferior phrenic artery injury detected and treated endovascularly

We report the rare case of delayed hemothorax (DHX) with an inferior phrenic artery (IPA) injury due to blunt thoracic trauma. Our case suggests that DHX almost always occurs early after injury, and endovascular treatment is an effective procedure for traumatic hemothorax including DHX.

The surgical stabilization of multiple rib fractures using titanium elastic nail in blunt chest trauma with acute respiratory failure

BACKGROUND

Blunt chest injuries are usually combined with multiple rib fractures and severe lung contusions. This can occasionally induce acute respiratory failure and prolong ventilations. In order to reduce the periods of ventilator dependency, we propose a less invasive method of fixing multiple rib fractures.

METHODS

Since October 2009, we have developed a new method to fix fractured ribs caused by blunt trauma. Rib fixations were performed using 2.0- or 2.5-mm intramedullary titanium elastic nails (TEN), with the help of video-assisted thoracoscopic surgery (VATS) and minimal thoracic incisions. All the patients' demographics and postoperative data were collected.

RESULTS

From January 2010 to December 2012, a total of 65 patients presenting with multiple rib fractures resulting in acute respiratory failure were included in the study. Twelve patients received the new surgical fixation. Rib fixations were performed at an average of 4 days after trauma. Patients were successfully weaned off ventilators after an average of 3 days. The average length of stay in the hospital and the intensive care unit (ICU) was shorter for the patients with fixation than for nonsurgical patients. All twelve patients returned to normal daily activities and work.

CONCLUSIONS

In the reconstruction of an injured chest wall, the VATS with TENs fixation in multiple rib fractures is feasible. This method is also effective in decreasing the length of the surgical wound. Because the structure of the chest cage is protected, the period of mechanical ventilation is shortened and the length of stay in the hospital and the ICU can be reduced.
