Early reoperation performed for the management of complications in patients undergoing general thoracic surgical procedures

Is VATS approach suitable in re-operations for postoperative hemothorax after pulmonary resection? Data analysis in a big volume thoracic center

OBJECTIVE

This study explored the safety and of feasibility of video-assisted thoracoscopy (VATS) in re-operations for post-operative hemothorax.

METHODS

The clinical data of patients underwent re-operations due to post-operative hemothorax after pulmonary resection in Shanghai Pulmonary Hospital from 2006 to 2018 were retrospectively analysed. The incidence of re-operations were analyzed. The mortality and morbidity were compared between thoracotomy and thoracoscopic procedure for re-exploration.

RESULTS

A total of 114 patients were included. The annual incidence rate ranged from 0.21 to 0.54%; the perioperative mortality was 2.6%; there were 114 cases of re-operations for hemothorax after 2012, including 62 cases in thoracoscopy group and 52 cases in open group. The durations of chest-tube drainage (7.2 ± 3.9 days vs 10.9 ± 12.0 days, P = 0.001) and length of stay in hospital (13.7 ± 6.7 days vs 18.9 ± 10.6 days, P = 0.002) in the thoracoscopic group were shorter than those in the open group. The thoracoscopic group had fewer post-operative complications as well (P = 0.023). Meanwhile, post-operative complications in the delayed group were significantly higher than those in the non-delayed group, with a longer length of hospital stay and higher hospitalization costs.

CONCLUSION

Complete VATS is safe and feasible for re-operation due to post-operative hemothorax and can be an alternative to thoracotomy. Delayed re-operations are associated with more post-operative complications and higher costs.

Surgery for lung cancer: postoperative changes and complications-what the Radiologist needs to know

Imaging findings after thoracic surgery can be misleading. Knowledge of the normal post-operative anatomy helps the radiologist to recognise life-threatening complications and conversely not to wrongly evoke a complication in cases of trivial post-operative abnormalities. In this educational article, we reviewed the expected patterns after thoracic surgery including sublobar resection, lobectomy, pneumonectomy and related techniques. Imaging aspects of frequent and less common complications and their typical imaging features are then presented.

Rapid development and rupture of a pulmonary cyst in the early postoperative period after pulmonary resection: A case report

Air leakage is a common complication after pulmonary resection, which is usually caused by direct lung damage during surgery. Herein, we describe a case in which a pulmonary cyst developed rapidly in the right lower lobe and ruptured 10 days after right upper lobectomy. A 49-year-old man, who was a heavy smoker, underwent thoracoscopic right upper lobectomy for primary lung cancer. No air leakage was observed postoperatively, and the chest drain tube was removed on postoperative day 1. Although his postoperative course was uneventful for more than a week, extensive subcutaneous emphysema developed unexpectedly on postoperative day 10. Computed tomography (CT) scan revealed a large pulmonary cyst in the right lower lobe that was not present before the right upper lobectomy. Surgery was performed on postoperative day 13, and it revealed a large thick-walled pulmonary cyst in the right lower lobe. The cyst was filled with blood clots, and air leaks were observed inside it, suggesting that the dissection of the pulmonary parenchyma caused its development. The cyst wall was sutured together with the pulmonary parenchyma, and no air leakage was subsequently observed. KEY POINTS: Significant findings of the study In patients with fragile pulmonary tissue, the pulmonary parenchyma may become dissociated after pulmonary resection and induce rapid development of a pulmonary cyst. Risk factors for pulmonary cyst development include upper lobectomy and emphysema. Pulmonary cysts are often formed in the lower lobe. What this study adds In patients with pulmonary emphysema post-upper lobectomy, the fragility of the pulmonary parenchyma and hyperinflation of the remaining lung may cause dissection of the pulmonary parenchyma, resulting in massive air leakage.

Analysis of trauma patients with unplanned returns to the operating room

Objectives

Trauma patients undergoing damage-control surgery may have a planned return to the operating room. In contrast, little is known about unplanned returns to the operating room (uROR) in trauma. The aim of this study was to identify risk factors for uROR in trauma patients. It is hypothesized that blunt trauma patients with uROR have higher mortality when compared to penetrating trauma patients with uROR. Additionally, it is hypothesized that trauma patients with uROR after thoracotomy have higher mortality than patients with uROR after laparotomy.

Material and Methods

A retrospective analysis of the National Trauma Data Bank from 2011-2015 including any adult patient with an uROR was performed.

Results

From 3.447.320 patients, 9.269 (0.2%) were identified to have uROR. In a multivariable logistic regression analysis, 27 independent predictors were identified for risk of uROR with the strongest independent risk factor being compartment syndrome (OR= 10.50, CI= 9.35-11.78, p <0.001). Blunt (compared to penetrating) mechanism was associated with higher risk for mortality in patents with uROR (OR= 1.69, CI= 1.14-2.51, p <0.001) as was re-incision thoracotomy (RT) compared to re-incision laparotomy (RL) (OR= 2.22, CI= 1.29-3.84, p <0.001).

Conclusion

The strongest risk factor for uROR in trauma is compartment syndrome. Both a blunt (compared to penetrating) mechanism and RT (compared to RL) are independent risk factors for mortality in patients undergoing an uROR.

Rethoracotomy for early complications: A marker for increased morbidity and mortality

Background

This study aims to examine the indications, timing and risk factors of rethoracotomy, analyze the postoperative results, and give suggestions to reduce the risks.

Methods

A total of 3,292 patients operated via thoracotomy between January 2006 and January 2017 were evaluated retrospectively. Demographic data, initial operative indications, surgical procedures, indications for rethoracotomy and preoperative risk factors, intraoperative findings and surgical methods, timing of rethoracotomy, morbidity and mortality results were analyzed of 66 patients (60 males, 6 females; mean age 59.4±12.4 years; range, 17 to 80 years) who were performed rethoracotomy before being discharged. Rethoracotomies performed within 72 hours after the first operation constituted the early and those performed after 72 hours constituted the late rethoracotomy group.

Results

Rethoracotomy was performed in average 4.7 days (range, 1 to 17 days). Early rethoracotomy was performed on 42 patients (1.3%) and 38 (90.4%) of these were due to hemorrhage. The most frequent indication for rethoracotomy was hemorrhage (n=41, 1.2%), followed by bronchopleural fistula (n=17, 0.5%). The other indications were chylothorax, lobe torsion, parenchymal air leak and collapse, and diaphragmatic laceration. Eight patients had rib fractures and all of these patients were over the age of 60. Eight patients who were performed rethoracotomy due to hemorrhage were using antiaggregant drugs. The postoperative morbidity and mortality rates were 33.3% (n=22) and 24.2% (n=16), respectively.

Conclusion

Rethoracotomy still has high morbidity and mortality rates. The main cause of rethoracotomy performed due to hemorrhage may be rib fractures or antiaggregant drugs. The most remarkable indications of rethoracotomy are hemorrhage and bronchopleural fistula.

Reoperation for hemostasis within 24 hours can get a better short-term outcome when indicated after lung cancer surgery

Background

Postoperative hemorrhage after lung cancer surgery is a potentially fatal complication. This study aimed to investigate the indications and timing of reoperation for postoperative hemorrhage after lung cancer surgery.

Methods

We identified all patients who underwent lung resection and mediastinal lymph node dissection for lung cancer between October 2001 and September 2015 at Sichuan Cancer Hospital, identifying 57 who had undergone reoperation for hemostasis. The records of these 57 patients were reviewed and analyzed.

Results

The most common postoperative hemorrhage site was the separation surface of the original pleural adhesions (29.8%). The median time interval between the initial operation and reoperation was 12 hours (range, 2-432 hours), and most patients (77.2%) underwent reoperation within 24 hours. The overall morbidity and mortality rates of reoperation were 50.9% and 5.3%, respectively. The morbidity rates of the early reoperation group (≤24 hours) and the late reoperation group were 43.2% and 77.0%, respectively, which were significantly different (P=0.033). The mortality rates of the early reoperation group and the late reoperation group were 0 and 23.1%, respectively, which were also significantly different (P=0.010).

Conclusions

Once indications of reoperation for postoperative hemorrhage after lung cancer surgery are identified, reoperation within 24 hours after the initial operation can get a better short-term outcome.

Minimally invasive procedures

Minimally invasive procedures, which include laparoscopic surgery, use state-of-the-art technology to reduce the damage to human tissue when performing surgery. Minimally invasive procedures require small "ports" from which the surgeon inserts thin tubes called trocars. Carbon dioxide gas may be used to inflate the area, creating a space between the internal organs and the skin. Then a miniature camera (usually a laparoscope or endoscope) is placed through one of the trocars so the surgical team can view the procedure as a magnified image on video monitors in the operating room. Specialized equipment is inserted through the trocars based on the type of surgery. There are some advanced minimally invasive surgical procedures that can be performed almost exclusively through a single point of entry-meaning only one small incision, like the "uniport" video-assisted thoracoscopic surgery (VATS). Not only do these procedures usually provide equivalent outcomes to traditional "open" surgery (which sometimes require a large incision), but minimally invasive procedures (using small incisions) may offer significant benefits as well: (I) faster recovery; (II) the patient remains for less days hospitalized; (III) less scarring and (IV) less pain. In our current mini review we will present the minimally invasive procedures for thoracic surgery.

Pneumothorax: an up to date "introduction"

The pneumothorax is an abnormal collection of air or gas in the pleural space that separates the lung from the chest wall. Like pleural effusion where a large abnormal concentration of fluid (>100 mL) is liquid buildup in that space, pneumothorax may interfere with normal breathing. A medical term that it is used is the collapsed lung, although that term may also refer to atelectasis. There are two major types of pneumothorax; there is one that occurs without an apparent cause and in the absence of significant lung disease, while the so called; "secondary" pneumothorax occurs in the presence of existing lung pathology. In a minority of cases, the amount of air in the chest increases markedly when a one-way valve is formed by an area of damaged tissue, leading to a third type of pneumothorax, called "tensioned".

Heimlich valve and pneumothorax

The Heimlich valve is a small one-way valve used for chest drainage that empties into a flexible collection device and prevents return of gases or fluids into the pleural space. The Heimlich valve is less than 13 cm (5 inches) long and facilitates patient ambulation. Currently there are several systems in the market. It can be used in many patients instead of a traditional water seal drainage system. The Heimlich chest drainage valve was developed so that the process of draining the pleural cavity could be accomplished in a safe, relatively simple, and efficient manner. This valve system has replaced the cumbersome underwater drainage bottle system. Moreover; the Heimlich valve system connects to chest tubing and allows fluid and air to pass in one direction only. This system functions in any position, and it does not ever need to be clamped, a regulated suction can be attached to it if necessary. The valve drains into a plastic bag that can be held at any level, allowing the patient undergoing chest drainage to be ambulatory simply by carrying the bag. In the current mini review we will present the Heimlich valve system and method of insertion.

Pneumothorax as a complication of central venous catheter insertion

The central venous catheter (CVC) is a catheter placed into a large vein in the neck [internal jugular vein (IJV)], chest (subclavian vein or axillary vein) or groin (femoral vein). There are several situations that require the insertion of a CVC mainly to administer medications or fluids, obtain blood tests (specifically the "central venous oxygen saturation"), and measure central venous pressure. CVC usually remain in place for a longer period of time than other venous access devices. There are situations according to the drug administration or length of stay of the catheter that specific systems are indicated such as; a Hickman line, a peripherally inserted central catheter (PICC) line or a Port-a-Cath may be considered because of their smaller infection risk. Sterile technique is highly important here, as a line may serve as a port of entry for pathogenic organisms, and the line itself may become infected with organisms such as Staphylococcus aureus and coagulase-negative Staphylococci. In the current review we will present the complication of pneumothorax after CVC insertion.

Pacemaker insertion

A pacemaker (PM) (or artificial PM, so as not to be confused with the heart's natural PM) is a medical device that uses electrical impulses, delivered by electrodes contracting the heart muscles, to regulate the beating of the heart. The primary purpose of this device is to maintain an adequate heart rate, either because the heart's natural PM is not fast enough, or there is a block in the heart's electrical conduction system. Modern PMs are externally programmable and allow the cardiologist to select the optimum pacing modes for individual patients. Some combine a PM and defibrillator in a single implantable device. PMs can be temporary or permanent. Temporary PMs are used to treat short-term heart problems, such as a slow heartbeat that's caused by a heart attack, heart surgery, or an overdose of medicine. Permanent PMs are used to control long-term heart rhythm problems. A PM can relieve some arrhythmia symptoms, such as fatigue and fainting. A PM also can help a person who has abnormal HRs resume a more active lifestyle. In the current mini review we will focus on the insertion of a PM and the possible pneumothorax that can be caused.

Pneumothorax from diagnosis to treatment, hands on course: Part II

Pneumothorax is a situation where air is inserted in the pleural space that separates the lung from the chest wall. Pneumothorax can be primary or secondary. There is also a third type called; tensioned. Based on the concentration of air and type of pneumothorax the proper treatment has to be selected. There are cases where the concentration is minimal and observation is enough and more severe cases where surgery is required. Currently there are many techniques used for the biopsy of lung lesions. The bronchoscope (forceps, fine needle aspiration), fine needle aspiration under computed tomography scan and endobronchial ultrasound (EBUS) are commonly used. However, all these techniques have in common a possible side effect; pneumothorax. In our current issue we will focus on the different minimally invasive techniques of pneumothorax management. Moreover, a presentation will be made for several systems that are being used for air or fluid aspiration.

Chest drainage systems in use

A chest tube is a flexible plastic tube that is inserted through the chest wall and into the pleural space or mediastinum. It is used to remove air in the case of pneumothorax or fluid such as in the case of pleural effusion, blood, chyle, or pus when empyema occurs from the intrathoracic space. It is also known as a Bülau drain or an intercostal catheter. Insertion of chest tubes is widely performed by radiologists, pulmonary physicians and thoracic surgeons. Large catheters or small catheters are used based on each situation that the medical doctor encounters. In the current review we will focus on the chest drain systems that are in use.

Video-assisted thoracic surgery and pneumothorax

Video-assisted thoracoscopic surgery (VATS) is a type of thoracic surgery performed using a small video camera that is introduced into the patient's chest via a scope. It is considered a minimally invasive technique where the surgeon is able to view the instruments that are being used along with the anatomy on which the surgeon is operating. The camera and instruments are inserted through separate holes in the chest wall also known as "ports", depending on the patient and problem there are surgeries with one port "uniport", two or three ports. These small ports have the advantage that fewer infections are observed. This allows for a faster recovery. Traditionally, thoracic surgery performed for diagnosis or treatment of chest conditions has required access to the chest through thoracotomy or sternotomy incisions. Vats minimally invasive technique has replaced in many cases thoracotomy or sternotomy. In our current review we will present this technique in detail.

Semi-Fowler vs. lateral decubitus position for thoracoscopic sympathectomy in treatment of primary focal hyperhidrosis

BACKGROUND AND OBJECTIVE

The aim of this study is to compare usefulness of Semi-Fowler position vs. lateral decubitus position for thoracoscopic sympathectomy in treatment of primary focal hyperhidrosis.

MATERIALS AND METHODS

From January 2009 to January 2010, 263 consecutive patients with palmar and axillar hyperhidrosis underwent thoracoscopic sympathectomy Th2-Th4. Patients were divided into two groups: group A (n=133) underwent thoracoscopic sympathectomy through lateral decubitus using double lumen endotracheal intubation, and group B (n=130) underwent thoracoscopic sympathectomy through Semi-Fowler supine position (semi sitting with arm abducted) using single lumen endotracheal intubation without insufflation of CO2, but with short apnea period. All operations were performed through two 5 mm operating ports, videothoracoscopic camera 0° and endoscopic ultrasound activated harmonic scalpel.

RESULTS

There were 107 males and 156 females with median age 30.31±8.35 years. Two groups were comparable in gender, age, severity of sweating. All operations were successfully performed with no complications or perioperative morbidity. For group A average operation time for both sides was 31.2±3.87 min and for group B average time was 14.19±4.98 min. In group B apnea period per one lung lasts 2.86±1.15 min and during that period observed saturation was 92.65%±5.66% without significant cardiorespiratory disturbances. Pleural drains were taken off on operation table after forced manually lung reexpansion. Patients were discharged from hospital for few hours, after the operation and radiologic confirmation of complete lung reexpansion.

CONCLUSIONS

Based on this data (shorter operating time, lack of incomplete lung collapse, insignificant apnea and better reexpansion of lungs) we concluded that thoracoscopic sympathectomy through Semi-Fowler supine position is highly effective and easy to perform for primary hyperhidrosis.

Open thoracotomy for pneumothorax

A thoracotomy is an incision into the pleural space of the chest. It is performed by surgeons (or emergency physicians under certain circumstances) to gain access to the thoracic organs, most commonly the heart, the lungs, or the esophagus, or for access to the thoracic aorta or the anterior spine. This surgical procedure is a major surgical maneuver it is the first step in many thoracic surgeries including lobectomy or pneumonectomy for lung cancer and as such requires general anesthesia with endotracheal tube insertion and mechanical ventilation, rigid bronchoscope can be also used if necessary. Thoracotomies are thought to be one of the most difficult surgical incisions to deal with post-operatively, because they are extremely painful and the pain can prevent the patient from breathing effectively, leading to atelectasis or pneumonia. In the current review we will present the steps of this procedure.

Barotrauma and pneumothorax

Barotrauma is physical damage to body tissues caused by a difference in pressure between a gas space inside, or in contact with the body, and the surrounding fluid. This situation typically occurs when the organism is exposed to a significant change in ambient pressure, such as when a scuba diver, a free-diver or an airplane passenger ascends or descends, or during uncontrolled decompression of a pressure vessel, but it can also happen by a shock wave. Whales and dolphins are also vulnerable to barotrauma if exposed to rapid and excessive changes in diving pressures. In the current review we will focus on barotraumas from definition to treatment.

Pleura space anatomy

The pleural cavity is the potential space between the two pleurae (visceral and parietal) of the lungs. The pleurae are serous membranes which fold back onto themselves to form a two-layered membranous structure. The thin space between the two pleural layers is known as the pleural cavity and normally contains a small amount of pleural fluid. There are two layers; the outer pleura (parietal pleura) is attached to the chest wall and the inner pleura (visceral pleura) covers the lungs and adjoining structures, via blood vessels, bronchi and nerves. The parietal pleurae are highly sensitive to pain, while the visceral pleura are not, due to its lack of sensory innervation. In the current review we will present the anatomy of the pleural space.

Physiology of the pleural space

The pleural cavity is created between the 4(th) and 7(th) week of embryologic development. These embryonic components of visceral and parietal pleurae develop different anatomic characteristics with regard to vascular, lymphatic, and nervous supply. There are two layers: a superficial mesothelial cell layer facing the pleural space and an underlying connective tissue layer. The pleura might present inflammatory response and maintenance of the pleural fluid is observed. The latter function is especially important in the mechanical coupling of the lung and chest wall. Fluid is filtered into the pleural space according to the net hydrostatic oncotic pressure gradient. It flows downward along a vertical pressure gradient, presumably determined by hydrostatic pressure and resistance to viscous flow. There also may be a net movement of fluid from the costal pleura to the mediastinal and interlobar regions. In these areas, pleural fluid is resorbed primarily through lymphatic stomata on the parietal pleural surface. In the current review we will present the physiology of the pleural space in a step by step manner.

Postoperative pain management

Postoperative pain is a very important issue for several patients. Indifferent of the surgery type or method, pain management is very necessary. The relief from suffering leads to early mobilization, less hospital stay, reduced hospital costs, and increased patient satisfaction. An individual approach should be applied for pain control, rather than a fix dose or drugs. Additionally, medical, psychological, and physical condition, age, level of fear or anxiety, surgical procedure, personal preference, and response to agents given should be taken into account. The major goal in the management of postoperative pain is minimizing the dose of medications to lessen side effects while still providing adequate analgesia. Again a multidisciplinary team approach should be pursued planning and formulating a plan for pain relief, particularly in complicated patients, such as those who have medical comorbidities. These patients might appear increase for analgesia-related complications or side effects.

Approach of the treatment for pneumothorax

Pneumothorax can occur in several situations such as; chronic obstructive pulmonary disease (COPD) where emphysema is observed or due to a biopsy for malignancy suspicion. In any case it is a dangerous situation that requires immediate attention and treatment. Pneumothorax can be divided in primary and secondary. Staging of pneumothorax is also very important. In our current editorial we summarize etiology and treatment of pneumothorax from a panel of pulmonary physicians, oncologists and thoracic surgeons.

Bronchoscopic interventions for severe COPD

Chronic obstructive pulmonary disease (COPD) causes severe handicap among smokers. Most patients have to remain under continuous oxygen therapy at home. Moreover, respiratory infections are very common among these patients and vaccination is obligatory against influenza. Emphysema and bronchiectasis are observed with computed tomography (CT) and in several situations these parenchymal damages are responsible for pneumothorax in one case and pseudomonas aeroginosa infection. Novel mini-invasive techniques are used currently for emphysema treatments which are described extensively throughout our current work.

Pneumothorax in sarcoidosis

While sarcoidosis is a relatively common but often underdiagnosed disease, pneumothorax appears to be a rare clinical event observed mostly at the late stages of the disease course. The precise underlying mechanism of such complication is unclear and probably involves the formation of bullae due to bronchial obstruction and retraction-collapse of distracted lung tissue. Thoracoscopic bullectomy represent the preferred treatment option for recurrent pneumothoraces. The administration of corticosteroids for the treatment of pulmonary sarcoidosis may have a protecting effect for such recurrences, but remains a controversial issue.

Human immunodeficiency virus infection and pneumothorax

Pneumothorax is a serious and relatively frequent complication of human immunodeficiency virus (HIV) infection that may associate with increased morbidity and mortality and may prove difficult to manage, especially in patients with acquired immunodeficiency syndrome (AIDS).

Acute respiratory distress syndrome and pneumothorax

Acute respiratory distress syndrome (ARDS) can occur during the treatment of several diseases and in several interventional procedures as a complication. It is a difficult situation to handle and special care should be applied to the patients. Mechanical ventilation is used for these patients and several parameters are changed constantly until compliance is achieved. However, a complication that is observed during the application of positive airway pressure is pneumothorax. In our current work we will present definition and causes of pneumothorax in the setting of intensive care unit (ICU). We will identify differences and similarities of this situation and present treatment options.

Unusual causes of pneumothorax

Pneumothorax is divided to primary and secondary. It is a situation that requires immediate treatment, otherwise it could have severe health consequences. Pneumothorax can be treated either by thoracic surgeons, or pulmonary physicians. In our current work, we will focus on unusual cases of pneumothorax. We will provide the etiology and treatment for each case, also a discussion will be made for each situation.

The role for medical thoracoscopy in pneumothorax

Pneumothorax is a life threatening situation that requires fast treatment. There are two major classifications: Primary and Secondary. Staging of pneumothorax is also very important for treatment. Treatment of pneumont can be performed either from thoracic surgeons, or pulmonary physicians. In our current work we provide up-to-date information regarding pneumothorax classification, staging and treatment from the point of view of expert pulmonary physicians.

Pneumothorax in cystic fibrosis

Pneumothorax is recognized as a common and life-threatening complication in cystic fibrosis (CF) patients, especially in those who are infected with P. aeruginosa, B. cepacia or Aspergillus, need enteral feeding, are diagnosed as suffering from allergic bronchopulmonary aspergillosis (ABPA), developed massive hemoptysis, and their respiratory function is seriously compromised. Structural impairment and altered airflow dynamics in the lungs of CF patients are considered as the main predisposing factors, but also inhaled medications and non-invasive positive pressure ventilation (NIPPV) could increase the risk of pneumothorax. Clinical presentation could range from dramatic to very mild. Management of spontaneous pneumothorax occurring to patients with CF is essentially similar to that for non-CF patients. Therapeutic options include intercostal tube drainage, video-assisted thoracoscopic surgery (VATS), and medical or surgical pleurodesis. Pneumothorax increases both short- and long-term morbidity and mortality in CF patients and causes significant deterioration of their quality of life.

Tube thoracostomy; chest tube implantation and follow up

Pneumothorax is an urgent medical situation that requires urgent treatment. We can divide this entity based on the etiology to primary and secondary. Chest tube implantation can be performed either in the upper chest wall or lower. Both thoracic surgeons and pulmonary physicians can place a chest tube with minimal invasive techniques. In our current work, we will demonstrate chest tube implantation to locations, methodology and tools.

Pneumothorax after transbronchial needle biopsy

Currently there several diagnostic techniques that re used by radiologists and pulmonary physicians for lung cancer diagnostics. In several cases pneumothorax (PNTX) is induced and immediate action is needed. Both radiologists and pulmonary physicians can insert a chest tube for symptom relief. However; only pulmonary physicians and thoracic surgeons can provide a permanent solution for the patient. The final solution would be for a patient to undergo surgery for a final solution. In our current work we will provide all those diagnostic cases where PNTX is induced and treatment from the point of view of expert radiologists and pulmonary physicians.

Transbronchial lung biopsy and pneumothorax

Mini-interventional procedures are used in the everyday clinical practice by pulmonary physicians and radiologists. Fine needle aspiration and biopsy forceps are the tools mostly used. During these procedures pneumothorax can occur and immediate treatment is necessary. In our current work, we will focus on minimal invasive techniques for biopsy and pneumothorax treatment.

Catamenial pneumothorax

Catamenial pneumothorax (CP) is the most common form of thoracic endometriosis syndrome, which also includes catamenial hemothorax, catamenial hemoptysis, catamenial hemopneumothorax and endometriosis lung nodules, as well as some exceptional presentations. Usually onset of lung collapse is less than 72 hours after menstruation. Most commonly occurs in women aged 30-40 years, but has been diagnosed in young girls as early as 10 years of age and post menopausal women (exclusively in women of menstrual age) most with a history of pelvic endometriosis. Diagnosis can be hinted by high recurrence rates of lung collapse in a woman of reproductive age with endometriosis. Moreover; CA-125 is elevated. Video-assisted thoracoscopy or medical thoracoscopy is used for confirmation. In our current work we will present all aspects of CP from diagnosis to treatment.

Penetrating trauma

Pneumothorax occurs when air enters the pleural space. Currently there is increasing incidence of road traffic accidents, increasing awareness of healthcare leading to more advanced diagnostic procedures, and increasing number of admissions in intensive care units are responsible for traumatic (non iatrogenic and iatrogenic) pneumothorax. Pneumothorax has a clinical spectrum from asymptomatic patient to life-threatening situations. Diagnosis is usually made by clinical examination and imaging techniques. In our current work we focus on the treatment of penetrating trauma.

Pneumothorax: observation

Pneumothorax based on the cause, it can be divided into two large categories; primary and secondary. The staging of pneumothorax plays a crucial role for treatment. Currently both thoracic surgeons and pulmonary physicians can handle efficiently treatment. Pulmonary physicians with the minimally medical thoracoscopy while thoracic surgeons with a more extensive intervention. Experience defines the outcome in most situations and not the method. In our current work we will present data regarding the observation of pneumothorax from a panel of experts.

Pneumothorax: from definition to diagnosis and treatment

Pneumothorax is an urgent situation that has to be treated immediately upon diagnosis. Pneumothorax is divided to primary and secondary. A primary pneumothorax is considered the one that occurs without an apparent cause and in the absence of significant lung disease. On the other hand secondary pneumothorax occurs in the presence of existing lung pathology. There is the case where an amount of air in the chest increases markedly and a one-way valve is formed leading to a tension pneumothorax. Unless reversed by effective treatment, this situation can progress and cause death. Pneumothorax can be caused by physical trauma to the chest or as a complication of medical or surgical intervention (biopsy). Symptoms typically include chest pain and shortness of breath. Diagnosis of a pneumothorax requires a chest X-ray or computed tomography (CT) scan. Small spontaneous pneumothoraces typically resolve without treatment and require only monitoring. In our current special issue we will present the definition, diagnosis and treatment of pneumothorax from different experts in the field, different countries and present different methods of treatment.
