Robotic Lobectomy Learning Curve Has Better Clinical Outcomes than Videothoracoscopic Lobectomy.

Introduction: The robotic-assisted (RATS) lobectomy learning curve is usually measured compared to an established videothoracoscopic (VATS) surgery program. The objective of our study is to compare the learning curves of both techniques. Methods: We performed an intention-to-treat analysis comparing the RATS vs. VATS lobectomies. Surgical time, conversions, complications, number of lymph nodes (LNs) and lymph node stations harvested, chest drainage duration, length of stay, readmissions, and 90-day mortality were compared between both groups. The learning curve was assessed using the CUSUM method. Results: RATS cases (30) and VATS cases (35) displayed no significant differences. The RATS learning curve was completed after 23 procedures while the VATS curve required 28 interventions. Complications appeared in four RATS procedures and in eight VATS patients. No differences in the number of LNs and harvested LN stations were reported. Four patients were readmitted in the RATS group, and eight in the VATS group. No 90-day postoperative mortality was observed in either group. The RATS group reported fewer chest tube days (3 (2-5) vs. 5 (4-5.8), p = 0.005) and hospital days (4 (3-6) vs. 5 (4-6), p = 0.023). Conclusions: The RATS curve appears shorter than the VATS curve. RATS lobectomies resulted in reduced chest tube duration and length of stay during the learning time period.

Starting a robotic thoracic surgery program: From wedge resection to sleeve lobectomy in six months. Initial conclusions / Inicio de un programa de cirugía torácica robótica: de resección en cuña a lobectomía con broncoplastia en seis meses. Conclusiones iniciales

Introduction: Robot-assisted thoracic surgery (RATS) is a rapidly expanding technique. In our study, we aimed to analyze the results of the process to adopt robotic surgery in our Department of Thoracic Surgery. Methods: This is an intention-to-treat analysis of a series of consecutive patients operated on using the RATS approach in our hospital from January 2021 to March 2022. Data were registered for patient characteristics, type of surgery, operative times, conversion rate, chest tube duration, length of hospital stay and complications. The IBM SPSS® statistical software was used for the statistical analysis. A cumulative sum analysis of the operating time was performed to define the learning curve. Results: During the study period, 51 patients underwent robotic surgery, including pulmonary and non-pulmonary interventions. In addition, 15 patients (29.4%) underwent non-pulmonary interventions: one pleural (2%), 2 diaphragmatic (3.9%), and 12 mediastinal (23.5%). Among the mediastinal surgeries, one conversion was necessary (8.3%) for a complex vascular malformation, and 11 were completed by RATS, including 7 (58.3%) thymomas, 3 (25%) pleuro-pericardial cysts, and one (8.3%) neurogenic tumor. Mean operative time was 141 min (104–178), mean chest tube duration was 0.9 days (0–2), and mean length of stay was 1.45 days (1–2). Thirty-six patients underwent lung surgery (70.6%). The complete RATS resections (34; 94.4%) included: 3 wedge resections (11.1%), 2 segmentectomies (3.7%), 28 lobectomies (81.5%), and one sleeve lobectomy (3.7%). Mean surgery time was 194.56 min (141–247), chest tube duration was 3.92 days (1–8), and length of stay was 4.6 days (1–8). Complications occurred in 4 patients (11.1%). No 90-day mortalities were registered. (AU)

Introducción: La cirugía torácica asistida por robot (RATS) es una técnica en rápida expansión. Nuestro objetivo fue analizar el resultado del proceso de adopción de la cirugía robótica en nuestro Departamento de Cirugía Torácica. Métodos: Este es un análisis por intención de tratamiento de una serie de pacientes consecutivos operados mediante el método RATS en nuestro centro desde enero de 2021 a marzo de 2022. Se registraron las características de los pacientes, tipo de cirugía, tiempos operatorios, tasa de conversión, duración del drenaje torácico, estancia hospitalaria y complicaciones. Para el análisis estadístico se utilizó el software IBM SPSS®. Se realizó un análisis de suma acumulada del tiempo de operación para definir la curva de aprendizaje. Resultados: Durante el periodo de estudio, 51 pacientes fueron sometidos a cirugía robótica.15 pacientes (29,4%) fueron sometidos a intervenciones no pulmonares: 1 pleural (2%), 2 diafragmáticas (3,9%) y 12 mediastínicas (23,5%). Entre las cirugías mediastínicas, fue necesaria una conversión (8,3%) por malformación vascular compleja y 11 fueron completadas por RATS, incluidos 7 (58,3%) timomas, 3 (25%) quistes pleuro-pericárdicos y 1 (8,3%) tumores neurogénicos. El tiempo operatorio medio fue de 141 minutos [104–178], la duración media del tubo torácico fue de 0,9 días [0–2] y la estancia media fue de 1,45 días [1–2]. 36 pacientes tuvieron cirugías pulmonares (70,6%). Las resecciones RATS completas (34; 94,4%) incluyeron: 3 resecciones en cuña (11,1%), 2 segmentectomías (3,7%), 28 lobectomías (81,5%) y 1 lobectomía con broncoplastia (3,7%). El tiempo medio de cirugía fue de 194,56 minutos [141–247], la duración del tubo torácico fue de 3,92 días [1–8] y la estancia hospitalaria fue de 4,6 días [1–8]. No se registró mortalidad a los 90 días. (AU)

A look ahead to promote the early detection of lung cancer: technical and cost implications of a confirmed diagnosis before surgery / Una mirada al futuro para promover la detección temprana del Cáncer de Pulmón: implicaciones técnicas y económicas de tener un diagnóstico confirmado antes de la cirugía

Objective: To compare the costs and length of hospital stay among patients with a confirmed diagnosis of lung cancer (LC) prior to surgery versus those without confirmation. Methods: This retrospective, single-center study was conducted in patients who underwent a surgical procedure for LC, with or without a pathologically confirmed LC diagnosis prior to surgery, between March 2017 and December 2019. The main outcomes were costs and length of hospital stay (LOS). Results: Among the 269 patients who underwent surgery for lung cancer between March 2017 and December 2019, 203 (75.5%) patients underwent surgery due to a histopathological diagnosis, and 66 (24.5%) because of a Multidisciplinary Cancer Committee indication. The unadjusted mean cost was significantly lower in Group II (patients with surgery based on Multidisciplinary Cancer Committee criteria) (Є2,581.80 ± Є1,002.50) than in Group I (patients with histopathological diagnosis) (Є4,244.60 ± Є2,008.80), P < 0.0001. Once adjusted for covariables, there was a mean difference of −Є1,437.20 in the costs of Group II, P < 0.0001. Unadjusted mean hospital stay was significantly longer in Group I (5.6 days) than in Group II (3.5 days). Conclusions: The results suggest that indicating surgical resection of lung cancer based on Multidisciplinary Cancer Committee criteria, rather than performing CT-guided percutaneous lung biopsy, may result in a significant decrease in cost and length of hospital stay.

Objetivo: Comparar los costes y la duración de la estancia hospitalaria entre los pacientes con un diagnóstico confirmado de cáncer de pulmón (CP) antes de la cirugía frente a los que no lo tienen. Métodos: Estudio retrospectivo y unicéntrico realizado en pacientes que se sometieron a un procedimiento quirúrgico de CP, con o sin diagnóstico de CP confirmado patológicamente antes de la cirugía, entre marzo de 2017 y diciembre de 2019. Los principales resultados fueron los costes y la duración de la estancia hospitalaria (LOHS). Resultados: Entre los 269 pacientes sometidos a cirugía por cáncer de pulmón entre marzo de 2017 y diciembre de 2019, 203 (75,5%) pacientes se operan por diagnóstico histopatológico y 66 (24,5%) por indicación del Comité Oncológico Multidisciplinar. El coste medio no ajustado fue significativamente menor en el Grupo II (pacientes con intervención quirúrgica basada en criterios del Comité Multidisciplinar del Cáncer) (2.581,8 ± 1.002,5Є) que en el Grupo I (pacientes con diagnóstico histopatológico) (4.244,6Є ± 2.008,8), p < 0,0001. Una vez ajustados por covariables, hubo una diferencia media de −1.437,2Є en los costes del Grupo II, p < 0,0001. La estancia hospitalaria media no ajustada fue significativamente mayor en el Grupo I (5,6 días) que en el Grupo II (3,5 días). Conclusiones: Los resultados sugieren que indicar la resección quirúrgica del cáncer de pulmón basándose en los criterios del Comité Multidisciplinar del Cáncer, en lugar de realizar una biopsia pulmonar percutánea guiada por TAC, puede suponer una disminución significativa del coste y de la duración de la estancia hospitalaria.

No 90-day mortalities were registered. CONCLUSIONS: The implementation of RATS was achieved with good clinical results and operative times for all indications. A rapid learning curve was accomplished in short time. Previous VATS experience, patient selection, team training and program continuity are fundamental to successfully develop a RATS program.

Tunnel technique for robotic-assisted left upper lobectomy.

Robotic-assisted thoracoscopy is a procedure that allows certain improvements over the traditionally used thoracoscopic procedures but still has disadvantages. Its association with dissection techniques such as the tunnel technique allows an approach to lungs with incomplete or fused fissures. We present the case of a 65-year-old female smoker with a 33-mm mass with a 13.7 SUVmax on positron emission tomography-computed tomography scans accompanied by biopsies that confirmed the diagnosis of small-cell lung cancer. After confirming that it was stage N0 and M0, surgical treatment was chosen. We performed a left upper lobectomy and thoracoscopic lymphadenectomy with robotic assistance; due to the presence of incomplete fissures, we used the fissure tunneling technique. This procedure ensured a safe dissection technique with the correct identification of the vascular and bronchial structures and reduced the risk of air leakage.

Osteocondroma escapular / Scapular osteochondroma

El osteocondroma es una lesión compuesta de hueso medular y cortical recubierta de una capa de cartílago hialino. La localización en la escápula es infrecuente. Se presentan 2 casos clínicos. Puede manifestarse con dolor o con síntomas por compresión de estructuras vecinas. La resección quirúrgica es el tratamiento de elección para el osteocondroma sintomático.

Osteochondromas are tumors composed of medullary and cortical bone with hyaline cartilage caps. Involvement of the scapula is uncommon. We report two cases. Patients may present with pain or symptoms due to compression of the adjacent structures. Surgery is the treatment of choice of symp­tomatic osteochondromas.
