Objective The objective of this study was to demonstrate extended thymectomy via the transcervical route. Methods With the use of the Rultract retractor (Rultract, Cleveland, OH), videothoracoscopy and single-lung ventilation allowed complete thymectomy. Results This article demonstrates complete resection of all the thymus from the anterior and superior mediastinum. Conclusions In selected patients, the transcervical route can used to completely resect the thymus, avoiding the morbidity of sternotomy.

Video Assisted Thoracoscopic Surgery

Objective There have been only small numbers of reports for video-assisted thoracoscopic surgery (VATS) lobectomy in children because of its technically demanding aspects. This study was performed to evaluate the safety and the efficacy of the VATS lobectomy compared with the conventional lobectomy by thoracotomy and to investigate the risk factors of thoracotomy conversion. Methods From May 2005 to October 2010, a total of 37 pediatric patients underwent VATS lobectomy and 28 pediatric patients underwent conventional lobectomy. The VATS lobectomy group consisted of relatively older patients compared with the thoracotomy group. Clinical outcomes from the two groups were analyzed and compared. Results Of the 37 patients in the VATS group, 8 patients (23%) required thoracotomy conversion and 29 patients (77%) were successfully operated on thoracoscopically. There were no in-hospital mortalities in both groups. Annual thoracotomy conversion rate has decreased from 50% in 2005 to 9% in 2010. There were no significant differences in the outcome between the VATS group and the thoracotomy group. Morbidities in the VATS group included prolonged drainage longer than 7 days (two patients), prolonged air leakage (two patients), and bleeding (one patient). There was no difference in the incidence of morbidities between the two groups. Univariate analyses revealed failure of single-lung ventilation (P = 0.007) and history of pneumonia (P = 0.001) to be risk factors of thoracotomy conversion. Conclusions Video-assisted thoracoscopic surgery lobectomy in children is a safe and effective treatment modality, with results comparable with those of conventional lobectomy. In the univariate analysis, failure of single-lung ventilation and history of pneumonia were the two factors related to thoracotomy conversion.

Thoracoscopic Technique

Delayed-onset pericardial effusion following cardiac surgery can give rise to significant morbidity due to its presentation as well as management by traditional surgical techniques. An institutional experience of a video-assisted thoracoscopic technique to create a pericardial window, with the advantages of a minimally invasive approach combined with excellent visualization in such patients, was reviewed. A retrospective analysis was conducted on all patients undergoing video-assisted thoracoscopic for delayed pericardial effusion after cardiac surgery from January 2001 to January 2006 at our center. Seven patients with echocardiographically diagnosed delayed tamponade underwent video-assisted thoracoscopy; 5 were receiving anticoagulants after valve replacement, and 2 had undergone heart transplantation. Pericardial windows were created under general anesthesia and single-lung ventilation using 2 to 3 trocars. Mean operative time was 45 min. There were no complications of the thoracoscopic technique. Video-assisted thoracoscopic creation of a pericardial window is safe and effective treatment for loculated pericardial effusions secondary to cardiac surgery.

Abstract: Introduction: Most modern thoracic operations are performed with single-lung ventilation balancing between convenient surgical approach and adequate gas exchange. The technical limitations include difficult airways or insufficient parenchyma for the intraoperative single-lung ventilation. Earlier, cardiopulmonary bypass was the only solution, however, today the extracorporeal membrane oxygenation is in the forefront. Aim: We retrospectively analysed our elective operations by use of venovenous ECMO to assess the indication, safety, perioperative morbidity and mortality. Patients and method: 12 patients were operated using venovenous (VV-) ECMO between 28 April 2014 and 30 April 2018 in the National Institute of Oncology. The main clinicopathological characteristics, data regarding the operation, the use of ECMO and survival were collected. Results: The mean age was 45 years, 2 patients had benign and 10 had malignant diseases. Extreme tracheal stricture was the indication for ECMO in 3 cases, while 4 patients had previous lung resection and lacked enough parenchyma for single-lung ventilation. 5 patients had both airway and parenchymal insufficiency. The average time of apnoea was 142 minutes without interruption in any of the cases. We did not experience any ECMO-related complication. We had no intraoperative death and 30-day mortality was 8.33%. Conclusion: In case of technical inoperability, when there is no airway or insufficient parenchyma for gas exchange, but pulmonary vascular bed is enough and there is no need for great-vessel resection, VV-ECMO can safely replace the complete gas exchange without further risk of bleeding. The use of VV-ECMO did not increase the perioperative morbidity and mortality. Previously inoperable patients can be operated with VV-ECMO. Orv Hetil. 2019; 160(42): 1655–1662.

Background and Objective: Hemodynamic consequences during video-assisted thoracoscopic surgery (VATS) with decortication during empyema drainage are unclear. The aim of the study was to assess the perioperative hemodynamic changes decortication during empyema drainage. Methods: A prospective study enrolled 23 patients with empyema who underwent decortication. Hemodynamic parameters were continuously obtained at 15 time points: supine two lung ventilation after induction, lateral decubitus position and two lung ventilation, lateral decubitus position and one-lung ventilation, every 5 min after decortication upto 60 minutes and at the end of surgery. We divided patients into three groups according to microorganisms, group 1: patients with no growth of organism; group 2: patients with staphylococcus aureus and pseudomonas; group 3: patients with streptococcus, yeast and fungus, gram-positive bacilli, and mycobacterium tuberculosis. The hemodynamic variables were recorded by the third-generation Vigileo/FloTracTM system and variables for each time interval were compared with the baseline by Wilcoxon Signed Ranks Test. Results: In group 1, hemodynamic parameters showed no significant changes over time. However, in group 2 and 3, both CO and CI increased 10 to 15 minutes after decortication and remained elevated during the remainder of surgery. However, SVR and SVRI decreased 10 to 15 minutes after decortication in both groups, especially, with a more significant decrease noted in group 2 than group 3. Conclusion: Close perioperative hemodynamic monitoring during decortication in empyema patients is required because of potential hemodynamic disturbances especially patients with toxic microorganisms.
