[Physiologic type reconstruction in upper gastrointestinal caustic strictures]. / A nyelés képességének helyreállítása lúgivás utáni nyelocsoszukületben.

The authors discuss their experience in the surgical treatment of caustic stenosis in the upper gastrointestinal tract. They present operative solutions using isoperistaltic transverse colonic segment in oesophageal stenosis caused by gastric outlet obstruction, or when these two presented together. Further indications for the above were bronchial or tracheo-oesophageal fistulas and oesophageal perforation. Late adaptation of the colonic grafts were measured by radiokinematography and histochemistry. The overall morbidity was 4.9%. Postoperative salivary fistulas closed spontaneously. Late postoperative complications (13.5%) were treated successfully. The multihaustral motility of the graft prevented the reflux, while the altered mucopolysaccharides of the colonic mucosa prevented the ulcer formation. Orv Hetil. 2019; 160(16): 613-618.

[Treatment of adult intrapulmonary sequestration with video-assisted thoracoscopic lobectomy]. / Felnottkori intrapulmonalis sequestratio kezelése videothoracoscopos lobectomiával.

INTRODUCTION: Surgical removal is the gold standard method for the treatment of pulmonary sequestration (PS); nowadays, video-assisted thoracoscopic lobectomy (VATS) is more frequently applied in the surgical treatment of malignant pulmonary tumours and appears to be suitable also in case of benign pulmonary diseases. We are the first in Hungary, who report three, radiologically identified intralobar PS treated with VATS. METHOD: Surgeries were performed in general anaesthesia with double-lumen separated ventilation in lateral decubitus position through two ports (1.5 cm camera port and 5-6 cm axillary working port, protected by a plastic ring). Results and cases: Two of the patients presented with the symptoms of haemoptysis and pneumonia, and the third patient after radiological screening (one 37 years old woman and 2 men, 39 and 46 years old). The nutritive artery was identified on the CT scans in all cases. We removed the right lower lobe in two cases and the left lower lobe in one case without major complications. CONCLUSION: We recommend the video-thoracoscopic lobectomy for the treatment of PS as a suitable treatment option.

[Surgical treatment of acute descending necrotising mediastinitis]. / Az acut descendáló necrotizáló mediastinitis sebészi kezelése.

INTRODUCTION: Acute descending necrotizing mediastinitis (DNM) is a severe septic inflammation of the mediastinum with necrosis, which progrediates rapidly and leads to death without adequate surgical treatment in 80% of cases. PATIENTS AND METHOD: 17 patients were treated with acute DNM between 1999 and 2012 at the Thoracic Surgical Department of Koranyi National Institute and Semmelweis University of Hungary. The infection source was primarily in the head-neck region with dental infections in eight cases, retro/parapharyngeal abscess in four patients, primary collar phlegmone and abscess in one case and two retrotonsillar abscesses. Further, in one case there was a previous operation (mediastinoscopy) in the history and in another case there was "difficult intubation process" (not recognized trachea-laesion) mentioned during abdominal operation. Primary exploration was performed from the neck in nine cases, thoracotomies plus collar incisions were carried out in four cases, athoracotomy only was done in one and orofacial exploration in further three patients. Disease progression could be evaluated by computer tomography which had to be followed by immediate surgery. RESULTS: Four patients needed two operations, five patients underwent exploration three times, while three patients needed 4 interventions four times. More than one anatomical region was explored in 70% of the cases. Based on our experience prognosis is affected by the time elapsed between detection and surgical intervention, age of the patient and comorbidites such as diabetes mellitus. We lost nine patients (53%), eight patients recovered and symptom free (47%). CONCLUSIONS: Successful treatment is based on early diagnosis, urgent elimination of the primary source, adequate exploration of the cervico-facial region, debridement, collar and upper mediastinal drainage. If the inflammation spreads below the azygos vein or the aortic arch, a right thoracotomy should be performed with wide mediastinal exploration, debridement, and thoracic suction-lavage drainage. Treatment should be completed with broad spectrum and targeted antibiotics as well as organ support. Mortality and morbidity can be reduced with prompt and aggressive therapy.

[Isolated bronchial resection for tumor]. / Tumor miatt végzett izolált hörgoresectio.

Tumors that are confined to specific areas of the airway (e.g. left main stem bronchus or the bronchus intermedius) can be removed with resections of the bronchus only and preservation of the parenchyma. During the period of January 2004 to February 2009 five patients underwent isolated bronchial resection for lung tumor with curative intent. In this study we analyzed the data of five men with a median age of 47.6 years (range 29­68 years). In four cases resection of the intermediate bronchus was performed, and in one case left main bronchus was removed. Intraoperative frozen section revealed negative bronchial resection margins in all cases. Four patients had carcinoid tumors, while one was diagnosed with chemodectoma. Minor postoperative complications were observed in two patients only. Isolated bronchial resection for lung tumor is associated with low morbidity and mortality. Lung sparing procedures are preferable in the above cases but sufficient experience and conditions are mandatory to achieve adequate results.

[Repair for anterior chest wall deformity by Nuss procedure performed in young adults and older adolescents]. / Elülso mellkasfali deformitás Nuss szerinti rekonstrukciója fiatal felnotteken és idosebb kamaszokon.

Results of 86 minimally invasive anterior chest wall reconstructions for pectus excavatum by the method of Nuss are evaluated retrospectively. Complications, possible ways of avoiding those and technical details of the operation are discussed. Nuss method is also evaluated in terms of suitability patients' age. Minimally invasive anterior chest wall reconstructions were performed in 86 patients in the last seven years. The average age was 21.4 years. There were no severe intra-operative complications. Four dislocations of the metal bar (12 and 53 days after chest reconstruction) were observed and treated by Nuss-technique. One metal bar had to be removed on the 13th postoperative day for local septic complication, and another one for significant sterile dislocation 14 months after the operation. One patient asked for removal of the metal bar because of pain. In one case bleeding from a small side-branch of the internal mammary artery was stopped by VATS technique, a small superficial lung injury was treated by thoracic drainage. Over 90 percent of patients were satisfied with the cosmetic results. Operating time and length of hospital stay gradually decreased throughout the years. Nuss technique can be performed safely in young adults for pectus excavatum with excellent long-term results. Less pain and shorter operating time of minimally invasive repair are the advantages of the procedure. Age above 30 years and previous open chest correction increases the risk for operation.

[Prevention and treatment of bronchopleural fistula using pedicled muscle flaps]. / Bronchopleuralis fisztulák megelozése es kezelése nyeles izomlebeny plasztikával.

Authors used pedicled muscle flaps for prevention and treatment of bronchopleural fistulas in 55 patients. Thirty five flaps were used for prevention and 21 for treatment of bronchial stump leak. After using 19 pectoral, 18 latissimus, 10 diaphragm, 3 intercostals, 2 serratus and 4 double muscle flaps, only two flap necrosis occurred due to insufficient flap perfusion. Latissimus and diaphragm flaps were used mainly for the purpose of prevention and the pectoral flaps for the treatment of bronchopleural fistula. The authors reveal the advantages, disadvantages and indications of using different muscle flaps for different purposes. Using this technique is an essential practice in everyday thoracic surgery.
