Comparison of uniportal robotic-assisted thoracic surgery pulmonary anatomic resections with multiport robotic-assisted thoracic surgery: a multicenter study of the European experience.

Background: Robotic-assisted thoracic surgery (RATS) has seen increasing interest in the last few years, with most procedures primarily being performed in the conventional multiport manner. Our team has developed a new approach that has the potential to convert surgeons from uniportal video-assisted thoracic surgery (VATS) or open surgery to robotic-assisted surgery, uniportal-RATS (U-RATS). We aimed to evaluate the outcomes of one single incision, uniportal robotic-assisted thoracic surgery (U-RATS) against standard multiport RATS (M-RATS) with regards to safety, feasibility, surgical technique, immediate oncological result, postoperative recovery, and 30-day follow-up morbidity and mortality. Methods: We performed a large retrospective multi-institutional review of our prospectively curated database, including 101 consecutive U-RATS procedures performed from September 2021 to October 2022, in the European centers that our main surgeon operates in. We compared these cases to 101 consecutive M-RATS cases done by our colleagues in Barcelona between 2019 to 2022. Results: Both patient groups were similar with respect to demographics, smoking status and tumor size, but were significantly younger in the U-RATS group [M-RATS =69 (range, 39-81) years; U-RATS =63 years (range, 19-82) years; P<0.0001]. Most patients in both operative groups underwent resection of a primary non-small cell lung cancer (NSCLC) [M-RATS 96/101 (95%); U-RATS =60/101 (59%); P<0.0001]. The main type of anatomic resection was lobectomy for the multiport group, and segmentectomy for the U-RATS group. In the M-RATS group, only one anatomical segmentectomy was performed, while the U-RATS group had twenty-four (24%) segmentectomies (P=0.0006). All M-RATS and U-RATS surgical specimens had negative resection margins (R0) and contained an equivalent median number of lymph nodes available for pathologic analysis [M-RATS =11 (range, 5-54); U-RATS =15 (range, 0-41); P=0.87]. Conversion rate to thoracotomy was zero in the U-RATS group and low in M-RATS [M-RATS =2/101 (2%); U-RATS =0/101; P=0.19]. Median operative time was also statistically different [M-RATS =150 (range, 60-300) minutes; U-RATS =136 (range, 30-308) minutes; P=0.0001]. Median length of stay was significantly lower in U-RATS group at four days [M-RATS =5 (range, 2-31) days; U-RATS =4 (range, 1-18) days; P<0.0001]. Rate of complications and 30-day mortality was low in both groups. Conclusions: U-RATS is feasible and safe for anatomic lung resections and comparable to the multiport conventional approach regarding surgical outcomes. Given the similarity of the technique to uniportal VATS, it presents the potential to convert minimally invasive thoracic surgeons to a robotic-assisted approach.

Mediastinitis / Mediastinitis

La mediastinitis se define como la inflamación aguda o crónica de las estructuras mediastínicas. Se presenta con una baja incidencia en general. La causa aguda más frecuente es la postesternotomía derivada de la cirugía cardíaca de revascularización con ambas arterias mamarias internas, con una incidencia del 0,4-5% y una mortalidad del 16,5 al 47%, siendo el vector más frecuente el Staphylococcus aureus. La perforación esofágica normalmente iatrogénica es la segunda causa de mediastinitis aguda, vehiculizada por flora orofaríngea común, con una mortalidad del 20 al 60%, dependiendo del momento del diagnóstico. La mediastinitis necrotizante descendente es la tercera causa, siendo el foco odontógeno en un 60% el origen y el Streptococcus β-hemolítico el microorganismo causante en el 71,5%. La tomografía computarizada es la herramienta diagnóstica de imagen más adecuada. El tratamiento es prácticamente siempre quirúrgico y su precocidad determina la supervivencia de estos pacientes. El choque séptico es el factor de peor pronóstico posquirúrgico (AU)

Mediastinitis is defined as acute or chronic inflammation of the mediastinal structures and generally has a low incidence. The most frequent acute cause is sternotomy following cardiac revascularization surgery with both internal mammary arteries, with an incidence of 0.4% to 5% and a mortality of 16.5% to 47 %. The most frequent vector is Staphylococcus aureus. Esophageal perforation, usually iatrogenic, is the second most frequent cause of acute mediastinitis, produced by common oropharyngeal flora, with a mortality rate of 20% to 60%, depending on the time of diagnosis. The third most frequent cause is descending necrotizing mediastinitis, the origin being an odontogenous focus in 60% and beta-hemolytic streptococcus the causative agent in 71.5 % of cases. The most accurate diagnostic imaging technique is computed tomography. Treatment is almost always surgical and survival depends on its early performance. The worst postsurgical prognostic factor is septic shock (AU)
