Abstract Background Myasthenia gravis (MG) is an autoimmune disease and early thymectomy has been recommended. After the introduction of VATS, the safety and effectiveness of carbon dioxide (CO2) insufflation in thoracic cavity (capnothorax) has been continuously controversial. This study aimed to compare the safety and effectiveness of ventilation methods in bilateral video-assisted thoracoscopic extended thymectomy (BVET) with capnothorax.Methods We retrospectively investigated the medical records of MG patients who underwent BVET between August 2016 and January 2018.Patients were divided into two groups: group D (n=26) for one-lung ventilation and group S (n=28) for two lung-ventilation. We set nine anesthesia time points (T0–T8) and collected respiratory and hemodynamic variables including arterial O2 index (PaO2/FiO2).Results The EtCO2 at T0, T1–T4, and T7 were insignificantly higher in group D than those in group S. The SpO2 at T1–T3 and T8 were significantly lower in group D than those in group S. The FiO2 in group S was lower than that in group D at all-time points. The number of PaO2/FiO2 ≤ 300 and PaO2/FiO2 ≤ 200 were significantly higher in group D than those in group S. Hemodynamic variables were not insignificantly different between the two groups at all-time points. The duration of surgery and anesthesia was shorter in group S than that in group D. Conclusions This retrospective study suggests that anesthesia using two-lung ventilation during BVET with capnothorax was a safe and effective method to improve lung oxygenation and reduce the operation and anesthesia time.

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.

Abstract BackgroundMediastinal teratomas are rare tumors that most frequently occur in the anterior mediastinum. The majority of these tumors are benign and slow growing. Due to their low malignant potential, the treatment for these tumors is surgical resection. The surgical management has shifted from invasive approaches such as a sternotomy to minimally invasive ones such as robotic-assisted thoracoscopic resections. Though many cases of mediastinal teratomas have been reported, we present a rare case of a locally advanced mediastinal teratoma requiring patient repositioning and change in ventilatory management mid-procedure to facilitate complete resection.Case PresentationA 43 year-old female was found to have an anterior mediastinal mass during work-up for an intermittent cough in 2009. Chest imaging and biopsy at the time showed evidence of a cystic teratoma without concerning features. She underwent imaging surveillance until 2018, when chest imaging showed increasing growth and worrisome radiologic features concerning for malignant degeneration. She underwent an elective robotic-assisted thoracoscopic resection utilizing double lung ventilation, but due to extensive involvement of the right lung, pericardium, superior vena cava, and right phrenic nerve the patient had to be repositioned and started on single lung ventilation mid-procedure to facilitate a safe and complete resection.ConclusionsAnterior mediastinal teratomas can be successfully removed by robotic-assisted thoracoscopic resections utilizing single lung ventilation. Though robotic-assisted thoracoscopic resection utilizing double lung ventilation can be effective in performing lung wedge resections and pleural biopsies, it is limited in removing locally advanced mediastinal tumors.

Abstract Intubated general anesthesia and single-lung ventilation are considered mandatory for conventional thoracoscopic surgery. Non-intubated thoracoscopic thymectomy is technically challenging. The aim of this article was to present the initial results of non-intubated subxiphoid-subcostal thoracoscopic thymectomy (NI-STT) under LMA management for patients with thymic tumor or myasthenia gravis (MG) and to investigate the feasibility and safety of the procedure. A retrospective analysis of patients undergoing NI-STT for thymic tumor or MG at our department from January 2017 to January 2020 was performed. The clinical characteristics and perioperative outcomes of the patients were reviewed and analyzed. A total of 61 patients were received NI-STT in this analysis, of which 19 patients with MG undergone an extended thymectomy and the rest (n=42) undergone a partial thymectomy. The anesthetic induction duration, surgical duration and global operating room duration were 24.83±12.27 min, 118.75±32.49 min and 173.51±41.80 min, respectively. The lowest SpO2 and peak EtCO2 during operation were 96.15±2.93 mmHg and 41.79±7.53 mmHg, respectively. The mean duration of chest drainage and postoperative hospital stays were 1.87 days, and 2.91 days, respectively. Three cases had sore throat and irritable cough and two cases suffered nausea and vomiting occurred. one patient suffered from an atrial fibrillation, two patients experienced pneumonia, and one patient suffered wound infection, respectively. There were no phrenic nerve paralysis and mortality occurred in the study group. The postoperative pain was low on 1,3, 7, 14, 30, 90 and 180 postoperative days. NI-STT was a technically safe and feasible approach for treating thymic tumors or MG. It could be an alternative to intubated single-lung ventilation for thymectomy in selected patients.

The FiO2 in group S was lower than that in group D at all time points. The number of PaO2/FiO2 ≤ 300 and PaO2/FiO2 ≤ 200 events was significantly higher in group D than in group S. Hemodynamic variables were not significantly different between the two groups at any time point. The duration of surgery and anesthesia was shorter in group S than in group D. Conclusions: This retrospective study suggests that anesthesia using two-lung ventilation during BVET with capnothorax is a safe and effective method to improve lung oxygenation and reduce anesthesia time.

Absztrakt Célkitűzés: A myasthenia gravis (MG) kezelésében számos nyitott, illetve minimálisan invazív thymectomia ismert. A tanulmány ugyanazon intézeten belül a transsternalis (TS), illetve kétféle minimálisan invazív thymectomia (video-assisted thoracoscopic extended thymectomy – VATET; unilateral video-assisted thoracoscopic surgery – UL-VATS) eredményeit hasonlítja össze. Anyag és módszerek: Három különböző időintervallumban 71 betegnél történt thymectomia MG miatt (60 nő, 11 férfi): 23 transsternalis thymectomia (1995. január–2004. szeptember), 22 VATET (2004. szeptember – 2009. augusztus) és 26 UL-VATS thymectomia (2009. szeptember – 2011. december). Az eredmények értékelésénél a műtéti idő, MG-hez társuló neurológiai és a műtét utáni sebészi szövődmények, valamint az MG státuszában az egyéves utánkövetéskor észlelt neurológiai változások szerepeltek. Eredmények: Perioperatív mortalitás nem fordult elő. A műtéti idő 112, 211, 116 perc (p = 0,001), a kórházi napok száma: 8,9, 5,6 és 4 nap (p = 0,001) volt a TS-, VATET- és UL-VATS-csoportban. Az MG-hez kapcsolódó postoperativ neurológiai szövődmények 21,7%, 18,2% és 7,7% (p = 0,365) értékeket mutattak. A sebészi szövődmény 4,3%, 13,7%, 0% (p = 0,118) volt. Az MG tüneteinek javulása 91,3%, 94,7%, 87,5% (p = 0,712), míg komplett remisszió 13%, 10,5%, 11,5% (p = 0,917) volt a TS-, VATET- és UL-VATS-csoportokban. Következtetések: A műtéti idő, valamint a kórházban eltöltött napok száma UL-VATS esetében volt a legrövidebb. A kisebb sebészi beavatkozáshoz alacsonyabb sebészi, illetve MG-s neurológiai szövődmények társultak. Az MG-tünetek javulásában mindhárom módszernél kiváló eredményt értek el.
