Robot-Assisted Radical Prostatectomy (RARP) Trifecta Learning Curve for Surgeons with Previous Experience in Laparoscopy.

Background and Objectives: Robot-assisted radical prostatectomy (RARP) is a complex surgery with a steep learning curve (LC). No clear evidence exists for how previous laparoscopic experience affects the RARP LC. We report the LC of three surgeons with vast experience in laparoscopy (more than 400 procedures), analyzing the results of functional and oncological outcomes under the "Trifecta" concept (defined as the achievement of continence, potency, and oncological control free of biochemical recurrence). Materials and Methods: The surgical experience of the three surgeons from September 2021 to December 2022, involving 146 RARP consecutive patients in a single institution center, was evaluated prospectively. Erectile disfunction patients were excluded. ANOVA and chi-square test were used to compare the distribution of variables between the three surgeons. LC analysis was performed using the cumulative sum control chart (CUSUM) technique to achieve trifecta. Results: The median age was 65.42 (±7.34); the clinical stage were T1c (68%) and T2a (32%); the biopsy grades were ISUP 1 (15.9%), ISUP 2 (47.98), and ≥ISUP 3 (35%). The median surgical time was 132.8 (±32.8), and the mean intraoperative bleeding was 186 cc (±115). Complications included the following: Clavien-Dindo I 8/146 (5.47%); II 9/146 (6.16%); and III 3/146 (2.05%). Positive margins were reported in 44/146 (30.13%). The PSA of 145/146 patients (99%) at 6 months was below 0.08. Early continence was achieved in 101/146 (69.17%), 6-month continence 126/146 (86%), early potency 51/146 (34.9%), and 6-month potency 65/146 (44%). Surgeons "a", "b", and "c" performed 50, 47, and 49 cases, respectively. After CUSUM analysis, the "Trifecta" LC peak was achieved at case 19 in surgeon "a", 21 in surgeon "b", and 20 in surgeon "c". Conclusions: RARP LC to accomplish "Trifecta" can be significantly reduced in surgeons with previous experience in laparoscopy and be achieved at around 20 cases.

Efecto de la pandemia en la cirugía radical del cáncer vesical / Effect of the pandemic on radical surgery for bladder cancer

Objetivo: El advenimiento de la pandemia de síndrome respiratorio agudo por coronavirus 2 (SARS-CoV-2) ha tenido un impacto en el manejo del resto de las patologías por la elevada presión asistencial generada. Por su historia natural, el cáncer vesical susceptible de cistectomía radical (CR) requiere especial atención. Nuestro objetivo es comparar los resultados perioperatorios y oncológicos de estos pacientes durante el estado de alarma respecto a la era pre-COVID en un centro de tercer nivel. Material y métodos: Estudio retrospectivo observacional descriptivo y analítico. Pacientes intervenidos de cistectomía radical por neoplasia entre abril de 2019 y marzo de 2021 divididos en dos grupos, abril 2019-marzo 2020 (n = 42) y abril 2020-marzo 2021 (n = 43). Resultados: Ambos grupos resultaron ser homogéneos. La mediana de espera desde la resección transuretral de vejiga hasta la realización de la CR no aumentó (82,5 vs. 83 días, p = = 0,860). No se observan tampoco diferencias en la estadificación TNM de las piezas quirúrgicas. Los tumores localmente avanzados no aumentaron significativamente (18 vs. 21, p = 0,580). La presencia de afectación ganglionar tampoco presentó diferencias significativas (10 vs. 13, p = 0,675). La estancia media disminuyó en un valor cercano a significación (mediana en días: 11 vs. 8, p = 0,056) sin que ello asociase un mayor número de complicaciones o de reingresos a los 30 días. Conclusión:: En nuestra serie no hemos constatado diferencias significativas en los resultados perioperatorios y oncológicos de pacientes tratados mediante CR durante la pandemia de COVID-19.

Introduction: The advent of the COVID-19 pandemic (caused by severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2] has had an impact on the management of other pathologies due to the high healthcare pressure generated. Due to its natural history, bladder cancer amenable to radical cystectomy requires special attention. We aim to compare the perioperative and oncological results of these patients during the alarm state with respect to the pre-COVID era in a tertiary care center. Material and methods: Observational descriptive and analytical retrospective research. Patients who underwent radical cistectomy because of bladder cancer between April 2019 to March 2021, divided in two groups, April 2019-March 2020 (n = 42) and April 2020-March 2021 (n = 43). Results: Both groups turned out to be homogeneous. The median wait time from transurethral resection of the bladder to radical cystectomy did not increase (82.5 vs. 83 days, p = 0.860). No differences were observed in the TNM staging of the surgical specimens. Locally advanced tumors did not increase significantly (18 vs. 21, p = 0.580). The presence of lymph node involvement did not present significant differences either (10 vs. 13, p = 0.675). The average stay decreased by a value close to significance (median in days 11 vs. 8, p = 0.056) without being associated with a greater number of complications or readmissions at 30 days. Conclusion: In our series, we have not found significant differences in the perioperative and oncological results of patients treated by radical cystectomy during the COVID-19 pandem
