1%) of the cumulative IF. Raf activity When considering publications per managing member, the first quintile averaged 11.9 publications (29.6 IF) per managing member, the last quintile 3.3 publications (8.0 IF) per member.
 The six units of the first quintile published on average 3.6 times more per managing member than the nine units in the last quintile and the average cumulative IF per member in the first quintile was almost five times higher. Further investigation must show whether this considerable difference in publication activity between the university units is also observed in other operative fields.

We aimed to provide a cross-sectional overview of current limitations or adaptions in lung transplant programs in Germany in from January to May 2020 due to the COVID-19 pandemia caused by severe acute respiratory syndrome coronavirus 2. A cross-sectional survey assessing various aspects of lung transplant activity was sent to all active lung transplant programs (n = 12) in Germany. Eight centers (66%) responded to the survey within the requested time frame. Four centers (50%) reported their activity is not restricted at all and four centers (50%) reported on moderate general limitations. The overall lung transplant activity in Germany from January to May 2020 contains 128 bilateral and 11 single lung transplantations, which is similar to the same period in the year 2019 (126 bilateral transplantations and 12 single lung transplantations). The results suggest that the influence of the COVID-19 pandemia on lung transplantation activity in Germany has been moderate so far. Nevertheless, adaptions such as extensive testing of donors and recipients were introduced to reduce the likelihood of infections and increase patient safety. Alertness to changes in COVID-19 reproduction rates might be required until effective antiviral therapy or vaccination is available.
 This is a preclinical cadaveric study to investigate the feasibility of a fully robotic McKeown esophagectomy in simultaneous rendezvous technique using the DaVinci X for transhiatal dissection and the DaVinci single port (SP) for transcervical dissection.
 Two transcervical esophagectomies with the DaVinci SP surgical system were performed as training procedures. In the third transcervical cadaveric procedure, the DaVinci SP was installed for the transcervical approach and the DaVinci X surgical system for the abdominal transhiatal phase. Primary outcomes were operating time and lymphadenectomy.
 The mobilization of the esophagus was successfully completed in 118 minutes by using the DaVinci SP for the transcervical phase and the DaVinci X for the transhiatal abdominal phase simultaneously. In total 18 lymph nodes were dissected in the thorax; 3 were located paratracheal right, 3 paratracheal left, 4 subcarinal, 4 para-aortic, 2 paraesophageal upper mediastinal, and 2 paraesophageal middle mediastinal.
 This preclinical study demonstrated that a fully robotic McKeown esophagectomy in simultaneous rendezvous technique using the DaVinci X for transhiatal dissection and the DaVinci SP for transcervical dissection was feasible with adequate lymphadenectomy in a cadaver model. Future research will elucidate the indications for the use of the fully robotic transhiatal and transcervical esophagectomy.

 Although tumor size is included in the definition of T descriptor in the tumor-node-metastasis (TNM) classification of many solid tumors, it is not considered for thymomas. This study aimed to assess the relationship of tumor diameters (the largest tumor diameter [LTD] and the mean tumor diameter [MTD]) with survival in thymoma patients undergoing surgical resection in a single center.
 The study included 127 thymoma patients (age, 49.2 ± 15.2 years; 65 males), who were evaluated based on pathological tumor sizes according to the LTD and MTD ([largest diameter + shortest diameter] / 2) and divided into three subgroups for each parameter as patients with an LTD of ≤5 cm, 5.1 to 10 cm, and >10 cm and patients with an MTD of ≤5, 5.1 to 10, and >10 cm.
 In thymoma patients, survival significantly differed according to the presence of myasthenia gravis (
 = 0.018), resection status (R0 or R1;
 = 0.001), T status (
 = 0.015), and the Masaoka-Koga stage (
 = 0.003). In the LTD subgroups, the overall survival of those with R0 resection was lower in those with an LTD of 5.1 to 10 cm than in those with an LTD of ≤5 cm (
 = 0.051) and significantly lower in those with an MTD of 5.1 to 10 cm than in those with an MTD of ≤5 cm (
 = 0.027). In the MTD subgroups, survival decreased as the tumor size increased.
 Both smaller tumor size and complete resection are associated with better survival in thymoma patients. Therefore, the largest or the mean tumor size might be considered as a criterion in the TNM staging for thymoma.

However, it requires additional management for reconstruction of the LSCA, which is associated with bleeding events. However, the fenestrated FET technique confers a risk of endoleakage from the fenestration site. We report our unique novel technique in which the proximal side of the hybrid stent graft is cut into V-shape around the subclavian artery and sutured continuously around the orifice of the subclavian artery during aortic stump fixation.
