[Traumatic rupture of the diaphragm in blunt injuries].

The authors present a group of 12 casualties operated on account of a traumatic rupture of the diaphragm. The rupture of the diaphragm was part of an associated thoracoabdominal injury or multiple injury. The casualties were examined within the framework of the diagnostic algorithm, in 11 of them rupture of the diaphragm was proved by spiral computed tomography. The diaphragm was injured in 7 subjects on the left and in 5 on the right. In 8 casualties during injury of the diaphragm also a serious intrathoracic injury was treated (in 5 laceration of the lungs) and of intraabdominal organs (in 4 laceration of the liver and in 2 laceration of the spleen). On the left side injuries of the diaphragm were always treated from laparotomy, on the right in 4 patients from thoracotomy. In 4 patients with concurrent injury of the intrathoracic and intraabdominal organs a thoracoabdominal approach was selected. During the postoperative period one female patient with multiple injuries died. The cause of death was contusion of the brain. According to the authors' experience it is useful to apply for early diagnosis of diaphragmatic injuries modern non-invasive imaging methods (spiral post-contrast computed tomography). The surgical approach depends on the presence of associated intrathoracic and intraabdominal injuries. The therapeutic results are limited by the presence of serious associated injuries.

[Indications for emergency surgery in thoraco-abdominal injuries].

PURPOSE OF THE STUDY: Under the conditions of an increasing number of car accidents and criminal injuries the thoracis and abdominal trauma is a source of a significant morbidity and mortality in blunt and penetrating mechanism of injury. On the basis of a group of patients operated on for blunt and penetrating injury of the chest and abdomen evaluation was made of the current indication and results of lifesaving surgery in case of these injuries. PATIENTS: The group included 68 patients requiring a lifesaving surgery for a blunt and penetrating injury of the chest and abdomen hospitalized between the beginning of 1966 and the end of April 2001. Forty-five patients sustained a blunt injury and 23 a penetrating injury. METHODS: In case of blunt injuries the indication for surgery was determined on the basis of clinical examination supplemented with a radiograph examination of the chest and spiral computer tomography. In case of penetrating stab wounds the surgery was indicated on the basis of clinical examination, in gunshot wounds by means of x-ray examination and spiral computer tomography performed in order to assess the scope of the injury of intraabdominal organs and the location of the projectile. Indicated on the basis of the examination in the blunt injury was thoracotomy in 6 cases, laporatomy in 34 cases and the combination of thoracotomy and laparotomy in 5 patients. In case of the penetrating injury thoracotomy was performed in 8 cases, laparotomy in 11 cases and the combination of thoracotomy and laparotomy in 4 patients. RESULTS: In the post-operative period 6 patients (9%) died: 3 patients with a polytrauma died from an irreversible damage caused by a protracted hemorrghagic shock, one female patient from the contusion of brain, one patient after splenectomy for an isolated injury died from cardiorespiratory failure and pneumonia, one patient with a stab wound of the left ventricle of the heart died from the heart failure by hypoxy. DISCUSSION: Indication for a lifesaving thoracotomy and laparotomy in our group of patients operated on corresponds to the overviews of surgeries in thoracoabdominal injuries presented in literature. The procedure in preoperative examination is identically limited by the stability of hemodynamics in the patient after the injury using mainly ultrasound and computer tomography of the stabilized patient. In contrast to a number of authors in our conditions we have not performed some of the intervention examinations such as diagnostic peritoneal lavage or thoracoscopy and laparoscopy. The improvement of results in patients operated on for thoracoabdominal injury is in our conditions given both by the timeliness of the operation in the availability of examination methods (US, spiral CT) and by adequate stabilization of the patient in the peroperative period at the emergency department. CONCLUSION: Priority indication for a lifesaving surgery in thoracoabdominal injuries is significant intraabdominal bleeding diagnosed on the basis of the result of the clinical examination in hemodynamically unstable patients. In a stabilized patient the lifesaving surgery is performed on the basis of the result of visualization methods (spiral computer tomography, ultrasound, angiography, endoscopy) revealing apart from significant bleeding also severe injuries of intrathoracic and intraabdominal organs. Protracted hypovolemic shock with the development of multi-organ failure or the occurrence of simultaneous severe associated injuries in polytrauma are the most frequent causes of mortality in patients operated on for thoracoabdominal injury.

[Empyema of the thorax].

The authors evaluated the therapeutic procedure and results in patients with empyema of the chest. From December 1996 till June 1998 at the Surgical Clinic of the Third Medical Faculty, Charles University Prague 21 patients with empyema of the chest were hospitalized. The most frequent cause of empyema of the chest was pneumonia in 13 patients (62%). In 16 patients (in 76%) the empyema was classified as the third stage of the disease. Decortication, the most frequent procedure, was performed in 16 patients, incl. three where it was done using videothoracoscopy. Surgical treatment was supplemented by antimicrobial treatment, either monotherapy or a combination of antimicrobial preparations. From the total number one patient died 25 days after thoracotomy and partial decortication with a mesiotheloma of the pleura. The other patients have no signs of relapse of empyema. According to the authors experience the selection of the surgical procedure depends on the stage of the disease. In the authors group decortication by the thoracotomic route was used most frequently.

[Intrathoracic occurrence of post-transplantation lymphoproliferation].

In the submitted case-history the authors wished to draw attention to serious complications after transplantation. Posttransplantation lymphoproliferation (PTLP) is a rare complication of organ transplantation, its incidence amounts to some 2% of organ recipients, in combined heart-lung transplantations the incidence is as high as 10%. The prerequisite of lymphproliferations is infection with the Epstein-Barr virus. The virus causes transformation of B lymphocytes and subsequent lymphoproliferation. Immunosuppressive preparations, due to their effect on Tlymphocytes promote this transformation. The decisive imaging method in tumoriform occurrence is high resolution computed tomography. Based on CT examination surgical biopsy is performed with subsequent in situ hybridization which confirms unequivocally the diagnosis of posttransplantation lymphoproliferation. Only on the basis of results of in situ hybridization treatment may be started which involves restriction or discontinuation of immunosuppressive treatment and administration of antiviral preparations. Frequently this treatment fails and must be discontinued on account of a rejection reaction of the organism. The prognosis in untreated forms is adverse.

[Tracheal replacement with a swine prosthesis].

In 12 experimental operations the authors tested the biocompatibility of a xenologous trachea from a pig which was used to replace a 5 cm defect of the trachea in a dog. After special preparation eliminating the antigenicity of the pig trachea the thus prepared graft was sutured into the thoracic portion of the dog trachea. The experiment could not be evaluated in two instances because the dog died on the operating table. In the remaining ten cases it was found that all anastomoses healed perfectly. The fibrous tissues of the tunica propria of the graft was replaced by granulation tissue. Across the anastomoses newly formed capillaries penetrated into the trachea where they caused chondrolysis. This led to a breakdown of the central portion of the prosthesis and stenosis in the airways with terminal respiratory failure. The mucosa of the graft was at some sites covered by metaplastically altered epithelium. Even a reinforcing vascular prosthesis did not prevent the breakdown of the wall of the xenologous graft. An asset for future work is the finding of a well healed suture between the graft and the trachea and evidence that newly formed blood vessels penetrated into the prosthesis.

[Videothorascopic surgery--initial experience].

Practical experience with the miniinvasive laparoscopic technique in abdominal surgery logically led to extension of this method to thoracic surgery. Video-assisted thoracoscopic operations hold their place in the treatment of spontaneous pneumothorax, pleural syndrome, benign tumours of the thoracic wall etc. A curative solution of malignant diseases by this route is so far controversial and is reserved only for specially defined cases. Experience from the authors' department is based on nine-month use of a thoracoscopic apparatus. The authors operated a total of 21 patients thoracoscopically, incl. pneumothorax 6x, fluidothorax 10x and tumourous disease of the lungs or mediastinum 5x. The use of thoracoscopy is controversial in metastases of the lungs and in thymectomy. With regard to the authors are against thoracoscopic indications in the latter conditions contemporary technical possibilities.
