Early postoperative results of sublobal lung resections performed with spontaneous ventilation combined with double lumen tube intubation. A new surgical method / Intubálással biztosított spontán légzés módszerével elvégzett sublobaris tüdoreszekciók korai mutét utáni eredményei. Új mutéti eljárás

Introduction. Non-intubated spontaneous ventilated (NITS) minimally invasive surgery (video-assisted thoracic surgery VATS) is a widespread procedure, but there are some doubts regarding its safety. We developed a safe method, spontaneous ventilation with intubation (SVI) to resolve these concerns. In this study, the early postoperative results of the SVI sublobar resections are presented. Methods. Between 2020 May 25 and 2021 March 26, 20 SVI VATS sublobar resection was performed with a double lumen intratracheal tube. Results. Surgeries were performed for 9 females and 11 males with a mean age of 66.1. The mean BMI was 27.8, FEV1 was 89.1%, and Carlson Comorbidity score was 6.1. The mean surgical time was 61.5 min, drainage time was 1.85 days and hospital stay was 3.35 days. Morbidity was found to be 5%. Primer lung cancer was removed in 9 cases, we performed 6 metastasectomies and in 5 cases benign lesion was removed. Conclusion. According to the early postoperative results spontaneous ventilated VATS sublobar resections with double lumen intratracheal tube can be considered a safe thoracic surgical method.

Laparoscopic-Assisted Percutaneous Endoscopic Gastrostomy Reduces Major Complications in High-Risk Pediatric Patients.

PURPOSE: Percutaneous endoscopic gastrostomy (PEG) is a safe method to feed patients with feeding difficulty. This study aimed to compare the outcomes of conventional PEG and laparoscopic-assisted PEG (L-PEG) placement in high-risk pediatric patients. METHODS: In our tertiary pediatric department, 90 PEG insertions were performed between 2014 and 2019. Children with severe thoracoabdominal deformity (TAD), previous abdominal surgery, ventriculoperitoneal (VP) shunt, and abdominal tumors were considered as high-risk patients. Age, sex, diagnosis, operative time, complications, and mortality were compared among patients who underwent conventional PEG placement (first group) and those who underwent L-PEG placement (second group). RESULTS: We analyzed the outcomes of conventional PEG placement (first group, n=15; patients with severe TAD [n=7], abdominal tumor [n=6], and VP shunts [n=2]) and L-PEG placement (second group, n=10; patients with VP shunts [n=5], previous abdominal surgery [n=4], and severe TAD [n=1]). Regarding minor complications, 1 (6.6%) patient in the first group underwent unplanned PEG removal and 1 (10%) patient in the second group had peristomal granuloma. We observed three major complications: colon perforation (6.6%) in a patient with VP shunt, gastrocolic fistula (6.6%) in a patient with Fallot-tetralogy and severe TAD, and pneumoperitoneum (6.6%) caused by early tube dislodgement in an autistic patient with severe TAD. All the three complications occurred in the first group (20%). No major complications occurred in the second group. CONCLUSION: In high-risk patients, L-PEG may be safer than conventional PEG. Thus, L-PEG is recommended for high-risk patients.

Contemporary management strategies of blunt tracheobronchial injuries.

BACKGROUND: Tracheobronchial injuries are rare but feasibly life-threatening conditions. A prompt diagnosis and early management can be lifesaving. Due to the unspecific symptoms and indirect radiological signs the diagnosis often delays. OBJECTIVES: We present a short series of patients suffering from tracheobronchial airway laceration. All the three patients had blunt thoracic or neck trauma and showed early signs of tracheobronchial injury. In the first case a 44-year-old woman was crushed by a bus. Subcutaneous emphysema, pneumothorax on chest computed tomography and hypoxaemia despite of chest tube suggested the presence of an airway injury. During operation a 4-cm-long tear of the trachea and a complete transection of the right main bronchus were found. In the second case a 12-year-old girl was crossed by a truck trailer. Early signs were respiratory failure, extended subcutaneous emphysema, blood clot in the larynx, pneumothorax on both sides. Chest CT showed pneumomediastinum. During the operation a longitudinal laceration was found separating the two main bronchi at the bifurcation. In the third case a 9-year-old boy was injured in a car accident, when the seat-belt crossed his neck. Spreading subcutaneous emphysema, pneumomediastinum and an overinflated endotracheal tube's cuff were found on CT. A completely transected trachea between the first and second tracheal rings was found. All three patients required fast intubation and bronchoscopic examination to confirm the diagnosis, and to identify the site of lacerations. All the patients underwent primary reconstruction and recovered successfully. CONCLUSIONS: In case of suspected tracheobronchial injury, a high index of suspicion is required for early diagnosis. Most commonly respiratory distress, subcutaneous emphysema and pneumothorax are found on physical examination. Prompt intubation below the site of the injury and early laryngo- or bronchoscopic examination have priority, as we did in our cases. A primary anastomosis is required with minimal resection during urgent operation. A better outcome is to be expected when extubation is done early after surgery. We offer ordinal steps that should be taken to lead to a prompt management and good long-term outcome based on the literature and our experiences.

Adenocarcinoma arising from a foregut cyst of the diaphragm: importance of multimodality treatment: a case report.

BACKGROUND: Benign foregut cysts usually develop in the thorax most of all in the mediastinum. Rare cases involving various abdominal organs, such as liver, stomach or pancreas have been previously published, mostly occurring in the retroperitoneum. CASE PRESENTATION: We herein present an adenocarcinoma of a foregut cyst involving the left side of the diaphragm, left lower lobe of the lung, and left lobe of the liver, successfully removed through multivisceral resection. In between drug holidays, postoperative oncological treatment has been ongoing for nearly 4 years. In terms of chemotherapy, FOLFOX 4 regime, capacitabine monotherapy and later on next generation sequencing has been attempted, although the patient refused the later treatment option. Despite multimodality (combined surgical and oncological) treatment, local- and later on loco-regional recurrence has been detected on follow-up staging, influencing further chemotherapy regime. Taking both the fairly unknown type of the tumor and uncertain response rate to oncological therapy into account, prolonged tumor pace with fairly stable general patient state was reached throughout the course of the disease. CONCLUSION: Through surgical tumor resection, and postoperative chemotherapy the patient managed to maintain an acceptable quality of life without major symptoms during ongoing treatment. During our own case, with multiple organ involvement, multivisceral resection, with multimodality treatment had considerable effect in prolonging the lifespan of the patient.

Conversion method to manage surgical difficulties in non-intubated uniportal video-assisted thoracic surgery for major lung resection: simple thoracotomy without intubation.

BACKGROUND: The major limitations of widespread use of non-intubated thoracic surgery (NITS) is the fear of managing complications. Here we present our practice of converting from uniportal video-assisted thoracic surgery (VATS) NITS to open NITS in cases of surgical complications. METHODS: The study period was from January 26, 2017, to November 30, 2018. Total intravenous anesthesia was provided with propofol guided by bispectral index, and the airway was maintained with a laryngeal mask with spontaneous breathing. Local anesthesia with 2% lidocaine at the skin incision, and intercostal and vagus nerve blockades were induced using 0.5% bupivacaine. For conversion with surgical indications, a thoracotomy was performed at the incision without additional local or general anesthetics. RESULTS: In 160 complete NITS procedures, there were 145 VATS NITS and 15 open NITS (9 conversions to open NITS and 6 intended NITS thoracotomies). In the 15 open NITS cases (2 pneumonectomies, 1 bilobectomy, 1 sleeve lobectomy, 7 lobectomies, 3 sublobar resections, 1 exploration), the mean operative time was 146.7 (105-225) and 110 (75-190) minutes in the converted and intended open NITS groups, respectively. There were no significant differences between systolic blood pressure (P=0.316; 95% CI, -10.469 to 3.742), sat O2% (P=0.27; 95% CI, -1.902 to 0.593), or propofol concentration in the effect site (P=0.053; 95% CI, -0.307 to 0.002) but significant differences in pulse (P=0.007; 95% CI, -10.001 to -2.72), diastolic blood pressure (P=0.013; 95% CI, -9.489 to -1.420) and in end-tidal CO2 (P=0.016; 95% CI, -7.484 to -0.952) before versus after thoracotomy, but there was no clinical relevance of the differences. CONCLUSIONS: For conversion with surgical indications during the VATS-NITS procedure, NITS thoracotomy can be performed safely at the site of the utility incision without the need for additional drugs, and the major lung resections can be performed through this approach.

The role of an overinflated endotracheal tube in the diagnosis of tracheal injuries / A túlfújt endotrachealis mandzsetta szerepe a légcsosérülések diagnosztikájában

Tracheobronchial injury is an uncommon, but often life-threatening condition. It is mostly caused by blunt thoracic or neck trauma, difficult or prolonged intubation associated with nasogastric tube insertion. An early diagnosis and treatment can be lifesaver. The diagnosis is often late because of atypical symptoms and unspecific radiological signs, and due to the presence of severe coexistent injuries. Generally, the classic hallmark during physical examination is a progressive, extensive surgical emphysema. Radiological signs are often atypical, which makes the diagnosis more difficult. The most frequent signs found on computed tomography are also unspecific, mostly surgical emphysema, pneumomediastinum or pneumothorax may be noted. We present three patients suffering from airway laceration caused by car accident, difficult intubation, and prolonged utilization of nasogastric and endotracheal tube. All the patients had an overdistended endotracheal balloon herniated outside the extratracheal space along the rupture of the tracheal wall. These external balloons were all detected on radiography. This is a direct and pathognomic sign of airway injury, suggesting complete rupture in the tracheal wall. In our report, we would like to highlight the diagnostic role of an overinflated cuff.

Internal Mammary Artery Compression After Pectus Excavatum Repair Does Not Increase Risk of Hemorrhagic Complications in Pediatric Patients.

Objectives: Minimal invasive repair of pectus excavatum (MIRPE) described by Nuss is the most popular correction nowadays of this deformity. During the introduction of the bars, they can hurt or compress the internal mammary arteries (IMA). The aim of this study was to observe the prevalence of IMA compression in children after MIRPE. Also, we examined if IMA obstruction increases the risk of complications at bar removal, and if these vascular changes are reversible. Materials and Methods: All patients operated on pectus excavatum in our tertiary pediatric surgical center between 2013 and 2019 were involved in the study. Data of age, sex, number of bars and characteristics of the deformity were examined. IMA flow was checked by Doppler ultrasound (DUS) after MIRPE and after bar removal, too. Results: Among 41 patients with mean age of 15.2 years there were 18 asymmetrical deformities, 23 sternal rotations. Mean pectus index was 4.01. After the Nuss procedure 7(9%) stenoses and 10(12%) occlusions of IMA were found on DUS. After bar removal 3 of 4 stenoses have resolved, but all examined occlusions (3/3) persisted. There were no complications during bar removals. Conclusion: IMA compression after MIRPE in children is uncommon, and is not influenced by severity of deformity. Obstruction of these vessels does not increase the risk of hemorrhagic complications at bar removal. Data of larger cohort are needed to determine reversibility of these changes.

[Successful multidisciplinary management of tetraplegia with a thoracic operation. Unicentric, mediastinal Castleman disease]. / Tetraplegia sikeres multidiszciplináris kezelése mellkassebészeti mutéttel. Unicentrikus mediastinalis Castleman-betegség esete.

Castleman disease is a rare lymphoproliferative disease the exact cause of which is not known. The diagnosis is based on the adequate histological examination. While in the unifocal form, the disease most commonly affects the chest, and symptoms may resolve as a result of intact excision of the tumour; other treatment methods may be performed in addition to or instead of surgical incision in the case of the multifocal form. We present the case of a patient with Castleman disease who received multidisciplinary treatment. Speech difficulty, dysphagia, and progressive paresis occurred in the upper and lower extremities of the 56-year-old male patient 18 weeks before his check-up examinations. Although the complaints temporarily resolved with plasmapheresis, surgical sampling could not confirm the origin of the mediastinal lymphadenomegaly detected with thoracic CT. The patient was admitted to our department to remove the 5 cm large subcarinal lymph node or to gain a tissue sample from it. On admission, significant atrophy, hypotonia and tetraplegia were seen in the four extremities, and areflexia was detected all over the body. The 5.5 × 3.5 cm large subcarinal lymph node conglomerate was removed from posterolateral thoracotomy. Histology was performed, Castleman disease was confirmed. 3 days after the surgery, the patient was able to move the extremities, and then on the 9th postoperative day, the patient could walk using a walking frame, and he was transferred back to the Department of Neurorehabilitation. At transfer, the muscle strength of the upper extremities was almost intact, and 4/5 muscle strength was detected in the lower extremities. After this, methylprednisolone, vitamin B1, calcium citrate, famotidine therapy was administered, and 2 weeks after his transfer, he was discharged home; at that time, the patient was able to walk safely without a walking frame. The symptoms resolved almost completely 3 months after the surgery. Diagnosis and treatment of Castleman disease are multidisciplinary tasks. If the patient is suitable for surgery, surgical removal has to play a key role in the treatment of unifocal Castleman disease. Orv Hetil. 2020; 161(1): 33-38.

Surgical treatment of awn aspiration causing bronchopleural fistula and bronchiectasis: case reports.

BACKGROUND: Aspiration of grass inflorescences is an extremely rare phenomenon with potential diagnostic difficulties. Due to its special shape, each coughing and respiratory action helps its migration towards the periphery of lung, resulting late-onset, life-threatening complications. The diagnosis has some difficulties for the reason that soon after the aspiration initial symptoms, such as coughing, wheezing or vomiting disappear and bronchoscopy is mostly negative. At least serious complications such as tension pneumothorax, bronchopleurocutaneous fistula or even spontaneous percutan elimination may develope. CASE PRESENTATION: We present two cases of pleuropneumonia resulting from aspiration of the head of barley grass. Soon after the accidents initial symptoms diminished, inflammatory markers improved and bronchoscopy was unable to confirm the presence of awn. Despite of conservative treatment (antibiotics, physiotherapy, bronchodilators, expectorants, and inhalation) localized pulmonary inflammation developed after 1 and 9 months showed up on chest computed tomography. After ineffective conservative treatment, surgical resections became inevitable in order to remove chronically inflamed parts (lobectomy, segmentectomy) and foreign bodies. Both patients recovered and were discharged home after successful interventions. CONCLUSIONS: Due to its peculiar shape and behaviour, awn inhalation is a special and atypical form of aspiration, thus great care and awareness is needed in its treatment. Negative bronchoscopic result does not exclude the presence of bronchial grass head. Symptomless child with negative bronchoscopy and improved inflammatory markers should be followed up thoroughly to recognize late complications in time. Regular diagnostic steps (chest ultrasound/X-ray) should be performed to localize potential chronic lung inflammation. Chest computed tomography is a valuable diagnostic tool for identifying and localising the foreign body. In cases with localized inflammation and peripheric localisation, segmentectomy can be a successful and safe alternative of lobectomy.
