[Splenectomy via the Transdiaphragmatic Approach]. / Splenektomie transdiafragmaticky.

The spleen is one of the most commonly injured organ in blunt traumas to the chest and abdomen. Splenic injury can be a serious complication of fracture of the left 9th to 11th rib. The authors present a case report of a 65-year-old male patient with a blunt trauma to the left chest and abdomen, diagnosed with multiple left rib fractures, left hemothorax and splenic injury with a small subcapsular hematoma with no signs of active splenic bleeding. Due to hemodynamic instability and a large volume of blood loss via the chest drain, the patient was indicated for emergency left thoracotomy. A perforation in the lower lobe of the left lung caused by rib fractures was found, which was treated with sutures. Furthermore, the diaphragm was examined, two ruptures were identified from which blood was coming out, and thus a phrenotomy was performed. The bleeding central splenic rupture came as a big surprise. A spleen preserving surgery was impossible, therefore a splenectomy had to be performed, followed by chest wall stabilization with splints. Transthoracic approach to manage the splenic injury through phrenotomy should not be used as a standard. In a selected group of patients with concomitant chest and upper abdominal organ injuries, the use of this surgical approach appears to be highly beneficial. Key words: splenic injury, splenectomy, thoracotomy, rib fractures, diaphragmatic rupture.

Antibiotic therapy of postoperative bronchopneumonia in patients after lung resections - single-site experience.

INTRODUCTION: Infectious complications after lung surgery are the most important factor that affects mortality and morbidity, prolongs hospital stays and increases financial costs. According to various sources, 30-day mortality after lung resections reaches 123%. Infectious complications account for 2075% of overall mortality. The infections most often present as postoperative pneumonia (POP), and their treatment is based on empirical and targeted antibiotic therapy. Any time lag in initiating effective antibiotic therapy significantly increases morbidity and mortality. Postoperative pneumonia is defined according to current guidelines of the American Thoracic Society of 2016 as nosocomial or ventilator pneumonia in patients after surgery. METHODS: Evaluation of risk factors, infectious agents, morbidity and mortality in patients after lung resections at a single site in the period from 1 January 2018 to 31 December 2019. RESULTS: Of our group of 190 patients, 21 (11.1%) patients had POP which was severe in 6 (33% with POP) patients, and 11 patients with POP required artificial oxygenation for saturation below 92%. Two patients with POP had to be intubated for respiratory failure, and 3 patients required noradrenaline circulatory support. One patient with severe POP died of multiorgan failure after developing refractory sepsis. CONCLUSION: Early identification of lung infection and early initiation of POP therapy are critical points for reducing morbidity and mortality after lung resections. Advanced antibiotic regimens for POP stratify the risk of mortality and infection with multidrug-resistant bacterial strains. However, the regimes require modification according to the epidemiological situation at the site with individualization of the specific procedure. Other research tasks include identification of valid markers of the initial stages of infection, and targeting of antibiotic therapy according to risk stratification and the relationship with physiological flora.

[Negative Pressure Wound Therapy as a Treatment Option for Extensive Post-Trauma Subcutaneous Emphysema]. / Moznosti lécby rozsáhlého poúrazového podkozního emfyzému pomocí podtlakové terapie.

Subcutaneous emphysema can be a secondary complication of chest trauma or one of the complications of ruptured bullae in advanced chronic obstructive pulmonary disease. Massive subcutaneous emphysema impairs the respiratory mechanics and affects the venous returns of the head and neck. It can lead to respiratory insufficiency with the need for mechanical ventilation. The treatment should focus on the primary pathology. Nonetheless, in patients with subcutaneous emphysema as the only but serious symptom, the treatment can zero in solely on this complication. The standard procedure consists in the insertion of chest drain which does not necessarily have to lead to successful treatment results. The authors present a case study of a 77-year-old man with major comorbidities, with extensive subcutaneous emphysema after blunt chest wall trauma, in which respiratory insufficiency developed. The chest drain was ineffective. The solution was to apply subfascial negative pressure therapy infraclavicularly to the area of the pectoral muscle, which made the subcutaneous emphysema almost immediately subside and which substantially improved the clinical condition of the patient. Local negative pressure therapy can be used as the method of choice for treating massive subcutaneous emphysema in patients, in whom the standardised treatment by chest drain with active suction mechanism failed and the lung is expanded in the pleural cavity, and for whom surgery is far too risky. Key words: negative pressure wound therapy, subcutaneous emphysema, rib fracture.

Hyperthermic intraoperative intrapleural chemotherapy and surgical cytoreduction as part of multimodal treatment of malignant pleural mesothelioma - case report M. Szkorupa1, D. Klos1, J. Chudacek1, J. Hanuliak1, M. Stasek1, O. Fischer2, R. Lemstrova3.

Malignant pleural mesothelioma is one of the most aggressive malignancies with a very poor prognosis. Multimodal treatment consisting of three modalities - chemotherapy, radiotherapy and cytoreductive surgery is optimal. The use of new therapeutic modalities, such as hyperthermic intraoperative intrapleural chemotherapy or photodynamic therapy can improve the current results of mesothelioma treatment. Combined hyperthermic intraoperative chemotherapy and cytoreductive surgery as part of multimodal therapy of malignant mesothelioma has been used since 2017 at the 1st Department of Surgery of University Hospital Olomouc. The authors report the case of a 47-year-old man with malignant epithelioid mesothelioma of the left pleural cavity. Following neoadjuvant chemotherapy, this patient underwent extrapleural pneumonectomy with intraoperative intracavitary hyperthermic chemotherapy. The postoperative period was complicated by circulatory instability and later by tension fluidothorax with signs of heart failure. Currently, 8 months have elapsed from the surgery and the patient remains without any signs of recurrence.

[Evolution of Opinions on Chest Wall Stabilisation and Our Experience]. / Vývoj názoru na stabilizace hrudní steny a nase zkusenosti.

PURPOSE OF THE STUDY Rib fractures represent one of the most common fractures sustained by 10-40% of all patients with blunt chest trauma, their incidence increases with age. In the current literature, however, new indication criteria continue to emerge. The purpose of this study is to assess the indication criteria, the timing of surgery and the use of individual plates in dependence on fracture location in our patients after the chest wall stabilisation in a retrospective analysis. MATERIAL AND METHODS Our group of patients (n = 349) included the patients who were hospitalised in the Trauma Centre of the University Hospital Olomouc from 1 January 2015 to 31 January 2019, of whom 16 patients were indicated for a surgery. In case of polytrauma, spiral CT was performed, while all patients with a more serious wall chest trauma underwent 3D CT chest wall reconstruction. The surgical approach was chosen based on the fracture location, most frequently posterolateral thoracotomy was opted for. The type of plates was chosen based on the location and type of the fracture. The most common was the lateral type of fracture. RESULTS The most common indication for surgery was multiple rib fractures with major chest wall disfiguration with the risk of injury to intrathoracic organs, present hemothorax or pneumothorax. The age of patients ranged from 44 to 92 years. 8 patients sustained a thoracic monotrauma, the remaining patients suffered multiple injuries, mostly craniocerebral trauma, pelvic or long bone fractures or parenchymal organ injury. The patients were indicated for surgery between 1 hour and 7 days after the hospital admission, on average 3 plates per patient were used and the most commonly used type of plate was the newly modified Judet plate made by Medin. All the patients underwent a surgical revision of pleural cavity, in 3 patients diaphragmatic rupture was found despite a negative preoperative CT scan. The duration of mechanical ventilation in polytrauma patients was 16 days, in thoracic monotrauma patients it was 2 days. CONCLUSIONS Prevailing majority of patients with a blunt chest trauma with rib fractures is still treated non-operatively, which is confirmed also by our group of patients. Nonetheless, correctly and early indicated stabilisation of the chest wall based on accurate indication criteria is of a great benefit to the patients. The aim of each and every trauma centre should be to develop a standardised protocol for the management of blunt chest trauma (the so-called "rib fracture protocol"), which comprises precisely defined criteria for patient admission, multimodal analgesia, indications for surgery, comprehensive perioperative and postoperative care and a subsequent rehabilitation of patients. Key words: rib fracture protocol, chest wall stabilisation, flail chest.

Successfull therapy of grade III leak after thoracic oesophagectomyusing endoscopic vacuum assisted closure therapy - a case study.

INTRODUCTION: Post-oesophagectomy leakage occurs in 1-30% of cases as a significant factor in postoperative morbidity and mortality, accounting for 40% of postoperative deaths. Endoscopic vacuum therapy (EVAC) is, besides stent therapy, clips and surgical therapy, a new endoscopic thera-peutic modality. CASE REPORT: A 72-year-old polymorbid female patient with Siewert type II adenocarcinoma of the distal esophagus (T1b, N0, M0) was indicated for resection of the upper stomach and lower thoracic esophagus from laparotomy and thoracotomy with reconstruction using double-stapling anastomosis. On postoperative day 12, a 3rd degree leakage with propagation into the right pleural cavity was proven on CT. Endoscopy showed a defect affecting 30% of the circumference with a 7×3×3 cm cavity. Because of the leak morphology, EVAC was indicated. The therapy comprised 12 sessions with 3-4-day intervals for a total duration of 40 days with 5 extraluminal and 7 intraluminal applications and negative pressure of 100-125 mmHg. The condition was complicated by global respiratory failure due to severe pneumonia. Artificial ventilation was terminated on the 58th postoperative day. The patient was discharged to a rehabilitation facility on the 90th postoperative day. The follow-up 3 months after discharge confirms satisfactory performance results with full replenishment. CONCLUSION: The therapy of complications of intrathoracic anastomoses after oesophagectomy has shown a trend toward reduced invasiveness and wider implementation of endoscopic methods. In spite of its shortcomings, the use of EVAC is a safe and highly effective therapeutic option even for extensive anastomotic defects. The future use, indications as well as relation to other therapeutic options require further evaluation. Key words: endoscopic vacuum therapy - esophageal leakage - esophagectomy complications - intraoperative endoscopy.

[Catamenial pneumothorax - case reports and literature review]. / Katameniální pneumotorax - kazuistiky a literální prehled.

AIM: Catamenial pneumothorax is menstrual cycle dependent and represents the most common form of thoracic endometriosis syndrome. Recurrences are very common even after surgical resection. DESIGN: Case reports and literature overview. SETTING: Department of Respiratory Medicine, Department of Surgery I, Department of Obstetrics and Gynecology, University Hospital, Palacky University, Olomouc. CASE REPORT: Two cases of catamenial pneumothorax are presented with repeated recurrences of right-sided pneumothorax even after surgical treatment. Histopathologic finding of pelvic endometriosis was shown in both patients. CONCLUSION: Catamenial pneumothorax is usually connected with thoracic endometriosis and also includes catamenial hemothorax, recurrent catamenial hemoptysis, catamenial pleural pain as well as endometriosis lung nodules. Multidisciplinary approach including pneumologist, thoracic surgeon and gynecologist with early postoperative hormonal treatment that deals with the main chronic systemic disease may lead to improved results, mainly reduced recurrence rates of catamenial and/or endometriosis related pneumothorax.

[Combined treatment of early tracheobronchopleural fistula after right tracheal sleeve pneumonectomy]. / Kombinované resení casné tracheobronchopleurální pístele po pravostranné sleeve pulmektomii.

Extended tracheo-bronchoplastic resection for lung cancer with carinal involvement ranks among technically demanding procedures. Despite certain progress in oncological therapy, this type of resection remains the only potentially curative treatment of NSCLC in this localization. However, given the severity of complications postoperative mortality is relatively high (711%). The main cause of death is tracheobronchopleural fistula complicated by thoracic empyema, bronchopneumonia and septic shock. If ARDS (acute respiratory distress syndrome) develops, the mortality rate rises up to 70%. The treatment of tracheobronchopleural fistula is arduous, long-term and essentially multidisciplinary. In this case report, the authors present the case of a 58 years old patient developing the tracheobronchopleural fistula early after carinal resection and sleeve pneumonectomy for a centrally localised squamous cell carcinoma of the right lung. The fistula was primarily sutured and secured using a muscular flap. For recurrence of the fistula, tissue adhesive glue was applied in combination with the introduction of a plastic stent, which resulted in healing of the tracheobronchopleural fistula.Key words: sleeve pulmonectomy carinal resection tracheobronchopleural fistula tracheobronchial stenting.

Sarcomatoid carcinoma of the lung -  a case report.

BACKGROUND: Sarcomatoid carcinoma (SARC) of the lung is a very rare and aggressive type of nonsmall cell lung cancer. It belongs to a group of poorly differentiated carcinomas with partial sarcomatoid differentiation or with a direct sarcoma component. Characteristic findings include a large tumor with an invasive tendency, early recurrence and systemic metastases. CASE: The authors present a case of SARC in the 77-year-old patient. Preoperative staging confirmed sarcomatoid carcinoma of the lower lobe of the left lung without generalization on PET/CT. However, an infiltration of more than 2/3 of the diaphragm was ascertained. A resection was performed -  a left lower lobectomy with resection of the diaphragm and its replacement by a muscle flap made from the latissimus dorsi muscle with vascular pedicle. Histological findings confirmed the dia-gnosis of sarcomatoid (pleomorphic) carcinoma pT3N0M0. The patient underwent adjuvant chemotherapy; recurrence and systemic dissemination of the disease occurred after 20 months; the patient died 21 months after the surgery.

Strategies of treatment of chest wall tumors and our experience.

INTRODUCTION: The only curative treatment of tumors of the chest wall (primary or secondary),despite all the progress in oncological therapy, is a surgical radical resection. The goal of the paper is the identification of a complication occurring after chest wall resections for a tumor (evaluation of morbidity and mortality). Furthermore, the tumor type and employed reconstruction method were analyzed. METHODS: A group of patients who underwent resection of the chest wall for primary or secondary tumors at the 1st Dept. Of Surgery, University Hospital Olomouc, was retrospectively analyzed. Age, diagnosis, procedure, histopathology of the tumor, preoperative and postoperative oncological treatment, preoperative co-morbidities, postoperative complications, the use of artificial lung ventilation and recurrences were recorded for all patients. RESULTS: 57 patients aged 16 to 86 years underwent a chest wall resection, 51% for a primary tumor and 49% for a secondary tumor. Resection of at least one rib or partial resections of the sternum were performed in every patient. Reconstruction with a mesh was employed in 22 patients; in 10 patients the mesh was covered with a muscle flap. Postoperative complications occurred in 10 patients (17.5%). CONCLUSION: It is necessary to follow the basic principles of treatment of chest wall tumors; therefore surgery of these tumors should be concentrated to specialized centers. Always before surgery, diagnosis should be established by means of a biopsy and generalization of the disease should be excluded, ideally using PET/CT. Most important for successful treatment is experience and interdisciplinary cooperation of the team. This results in a low mortality and morbidity rate, which was confirmed by our results. KEYWORDS: chest wall tumors chest reconstruction sternum resection - treatment of chest wall tumors chondroma.

[Surgery of the pulmonary metastases]. / Chirurgie plicních metastáz.

INTRODUCTION: Surgical resection of lung metastases of epithelial and mesenchymal tumors has an irreplaceable position in the complex treatment of advanced stages of these malignancies. Among the most significant prognostic factors affecting longterm survival of these patients are: parameter of complete resection, number and size of metastases, histological type of primary tumor, lymph node involvement, DFI (Disease Free Interval) and biological aggressiveness of the tumor or TDT (Tumor Doubling Time). AIM: retrospective analysis of patients with lung metastases of epithelial and mesenchymal tumors operated on at the I. Department of Surgery from 2005 to 2011. MATERIAL AND METHODS: The authors present a set of 50 patients and evaluation of their age, gender, type of primary tumor, number of metastases, occurrence of bilateral metastases, repeat metastasectomies, duration of DFI, type of operation and selected approach and performance of mediastinal lymphadenectomy. The probability of five-year survival, relationship between survival on DFI, difference in survival between metastases of colorectal cancer versus renal cancer and the influence of repeated metastasectomies and number of metastases on survival were statistically analyzed. RESULTS: Sixty operations were performed on a set of 50 patients (average age 61.2 years). Forty-two procedures were performed by thoracotomic approach. A solitary metastasis was discovered in 43 patients; in 8 patients, more than 3 metastases were resected. Repeated metastasectomies were performed 10 times. Mediastinal lymphadenectomy was performed in 21 cases. The most frequent procedure was extraanatomic resection (28×). Fourteen patients had DFI < 12 months, 19 patients had DFI 12-36 months and 17 patients had DFI > 36 months. Average survival was 66.9 months; the probability of five-year survival was 0.549 (54.9%). A relationship between DFI and survival was not discovered. There was no statistically significant difference in survival after metastasectomy for colorectal cancer and renal cancer. A relationship between survival interval and number of metastases and repeated metastasectomies was not discovered. CONCLUSION: Surgical resection of lung metastases plays an important role in multidisciplinary care, assuming a precise selection of patients indicated for this treatment. When properly adhering to the indication criteria, very positive results of long-term survival may be expected.

[Biomarkers in the detection of minimal systemic dissemination in lung cancer patients]. / Biomarkery detekce minimální systémové diseminace u nemocných s karcinomem plic.

INTRODUCTION: Minimal systemic disease (MSD) means the presence of circulating or disseminated tumour cells in mesenchymal compartments of a patientts' body (lymphatic nodes, blood or bone marrow). The aim of our pilot study was to identify sensitive and specific markers for MSD detection in 50 lung cancer patients, who underwent curative surgery in the I. Department of Surgery, Faculty of Medicine and Dentistry, Palacky University and Faculty Hospital Olomouc in 2009 and 2010. MATERIAL AND METHODS: Absolute gene expression of carcinoembryonic antigen (CEA), epidermal growth factor receptor (EGFR1), lung-specific X protein (LUNX) and hepatocyte growth factor receptor (c-met) was determined in peripheral blood, bone marrow and pulmonary blood of 50 lung cancer patients using real-time reverse transcriptase-polymerase chain reaction (real-time RT-PCR). RESULTS: (1) The LUNX marker is specific and sensitive for MSD detection in lung cancer patients. (2) The CEA positivity for MSD in the bone marrow correlated significantly with histopathological grading (GI-GIII). (3) Higher expression of CEA and c-met was found in pulmonary blood of patients with hilar or mediastinal lymphadenopathy. (4) Higher expression of MSD markers (CEA in bone marrow, c-met in peripheral blood and LUNX in pulmonary blood) correlated with higher pTNM classification. CONCLUSION: Minimal systemic disease detection in lung cancer patients is technically feasible using sufficiently sensitive and specific markers for RT-PCR. Minimal systemic disease detection can be used to guide further systemic treatment. This theory must be validated in a larger group of patients and correlated with clinical data, especially with survival data.

[Burkitt's lymphoma of the caecum as a rare cause of acute abdomen: a case report]. / Burkittuv lymfom céka jako vzácná prímina náhlé príhody brisní--kazuistika.

Burkitt's lymphoma is a highly aggressive B-lymphoproliferative disorder. Clinically it most often manifests with extranodal involvement, typically affecting the gastrointestinal tract as a large and rapidly proliferating tumor mass, which may present as acute abdomen. We present a case report of a young man admitted with signs of acute appendicitis. A tumor of the ileocaecal junction was discovered perioperatively and resolved by a right-sided hemicolectomy. Histological examination of the tumor confirmed Burkitt's lymphoma. On the ninth postoperative day, the patient developed signs of ileus and a follow-up CT scan showed tumor masses in the area of the ileotransversoanastomosis. He was transferred to undergo radical adjuvant chemotherapy. Intestinal passage was restored during the next two days. Our aim is to report on the limited role of surgical treatment in this type of malignancy, due to the extremely rapid proliferation of the tumor tissue, when the tumor can grow back to its original size over a period of a few hours or days.

[Solitary fibrous tumor of pleural cavity]. / Solitární fibrózní tumor pleurální dutiny.

INTRODUCTION: Solitary fibrous pleural tumor (SFT) is, in most cases, a benign tumor arising from mesenchymal cells. A malignant version of the tumor is rare and its histopathological evaluation is quite difficult. Usually, SFT affects visceral, as well as parietal pleura, most commonly in a form of a pedunculated tumor. The treatment is primarily surgical, with the aim to perform radical resection even in case of infiltrative growth. Adjuvant therapy is indicated in malignant varieties of the tumor, however, its outcome is uncertain. SFTs have fairly high relaps rates and their prognosis and the risk of relaps can be estimated based on morphological indicators and assessment of their biological characteristics. AIM: Retrospective analysis of SFT group of patients, who were operated from 2006 to 2009. SUBJECTS AND METHODS: The authors present a group of 11 patients with solitary fibrous pleural tumors, who were operated at the Ist Faculty Hospital Surgical Clinic of the LF UP (Medical Faculty of the Palacky University) in Olomouc from 2006 to 2009. The authors assessed the patient's age, size of the tumors, types of the procedures, biological characteristics of the tumors, duration of hospitalization and complication rates. CONCLUSION: Solitary pleural tumors are fairly rare tumors arising from fibroblastic cells, Its biological characteristics is uncertain and, in some cases, is difficult to assess based on immunohistochemical, as well as morphological indicators. The treatment is surgical--removal of the tumor as far as the healthy tissue. Adjuvant therapy is indicated in malignant varieties of the tumor. SFT relaps rate is fairly high, depending on the tumor biological characteristics and its morphological features.

[The results of provisions for the rational use of antimicrobial drugs--survey in a regional polyclinic]. / Výsledky opatrení k racionálnímu vyuzívání antimikrobiálních léciv--sonda v územní poliklinice.

The author discusses the effect of provisions for the rational use of antimicrobial drugs, issued at the end of 1986. He draws attention to the reduced frequency of antimicrobial treatment in the first half of 1987 in surgeries of the territorial polyclinic, as compared with the same period in 1985. The decline is significant even after standardization with regard to the more favourable epidemiological situation in 1987, as compared with 1985. The author also draws attention to the significant rise of the number of microbiological examinations in conjunction with antimicrobial treatment. He evaluates the general decline of consumption of antimicrobial drugs by 30% in the catchment area of the polyclinic and the altered structure of prescribed antimicrobial drugs. The results of the work, which has the character of a pilot study, indicate the favourable effect of the mentioned provisions for the rational treatment with antimicrobial drugs.

[Roentgen diagnosis of intervertebral disk calcification in children]. / Zur Röntgendiagnose der Bandscheibenverkalkungen im Kindesalter.

From an analysis of their own patients and of the radiological appearances of juvenile disc calcification as described in the literature, the authors have subdivided the evolution of this condition into three phases. The third phase (residual effects) is given the most detailed consideration.
