A comparison of perioperative outcomes between extraperitoneal robotic single-port and multiport radical prostatectomy with the da Vinci Si Surgical System / 亚洲男科学杂志(英文版)

To evaluate outcomes between extraperitoneal robotic single-port radical prostatectomy (epR-spRP) and extraperitoneal robotic multiport radical prostatectomy (epR-mpRP) performed with the da Vinci Si Surgical System, comparison was performed between 30 single-port (SP group) and 26 multiport (MP group) cases. Comparisons included operative time, estimated blood loss (EBL), hospital stay, peritoneal violation, pain scores, scar satisfaction, continence, and erectile function. The median operation time and EBL were not different between the two groups. In the SP group, the median operation time of the first 10 patients was obviously longer than that of the latter 20 patients (P < 0.001). The median postoperative hospital stay in the SP group was shorter than that in the MP group (P < 0.001). The rate of peritoneal damage in the SP group was less than that in the MP group (P = 0.017). The pain score and overall need for pain medications in the SP group were lower than those in the MP group (P < 0.001 and P = 0.015, respectively). Patients in the SP group were more satisfied with their scars than those in the MP group 3 months postoperatively (P = 0.007). At 3 months, the cancer control, recovery of erectile function, and urinary continence rates were similar between the two groups. It is safe and feasible to perform epR-spRP using the da Vinci Si surgical system. Therefore, epR-spRP can be a treatment option for localized prostate cancer. Although epR-spRP still has a learning curve, it has advantages for postoperative pain and self-assessed cosmesis. In the absence of the single-port robotic surgery platform, we can still provide minimally invasive surgery for patients.

Artroplastía total de rodilla con asistencia de brazo-robótico: resultados clínicos postoperatorios tempranos / Robotic arm-assisted total knee arthroplasty: early postoperative results

OBJETIVO: Describir los resultados clínicos postoperatorios tempranos de la primera serie de pacientes operados de artroplastía total de rodilla (ATR) con asistencia de brazo-robótico en Latinoamérica. MATERIALES Y MÉTODOS: Estudio prospectivo de 52 pacientes (53 rodillas) con gonartoris tricompartimental sintomática operados de ATR primaria con asistencia de brazo-robótico (RIO-MAKO) de manera consecutiva, con seguimiento a 2 meses postoperados. No se excluyeron pacientes. Se utilizó el mismo protocolo anestésico y de rehabilitación. Se realizó revisión de fichas clínicas para recolectar los siguientes resultados: tiempo de isquemia quirúrgica, estadía hospitalaria, tiempo a marcha, dolor postoperatorio diario [Escala visual análoga (EVA)], uso de opioides, rangos de movilidad articular (ROM), pérdida sanguínea, complicaciones y eje mecánico postoperatorio. RESULTADOS: Tiempos de Isquemia: 82 minutos (60­120). Estadía Hospitalaria: 4 días (2­12). Dolor postoperatorio: EVA el mismo día operatorio de 0 (0­10) y previa al alta de 0 (rango 0­4), con 0,3 purgas (0­6,5) de opioides por paciente. Tiempo a marcha (día logrado): 1 día (1­3), cuarenta y cinco pacientes (84,9%) iniciaron la marcha el primer día postoperatorio. ROM (Extensión-Flexión): Aumento progresivo durante el seguimiento. En el control ambulatorio de los dos primeros meses [23 días (13­50)], veintiún pacientes (40%) alcanzaron un ROM mayor o igual a 0­90° y once (20%) presentaron un ROM funcional máximo (0­120°). Pérdida sanguínea: Siete pacientes (13,2%) requirieron transfusión. Complicaciones: un paciente (1,89%) presentó una dehiscencia del cierre de la artrotomía. No hubo otras complicaciones. Eje mecánico postoperatorio: 179,1° (178,2­180). DISCUSIÓN: Los resultados concuerdan con la evidencia descrita en otras regiones, sugiriendo que la asistencia de brazo-robótico permite resultados postquirúrgicos reproducibles. CONCLUSIÓN: Los resultados clínicos postoperatorios tempranos de esta serie de pacientes operados de ATR con asistencia de brazo-robótico, muestran una baja percepción del dolor, con bajo consumo de opioides, una rápida recuperación funcional de la marcha y ROM, y excelentes resultados desde el punto de vista del eje mecánico postoperatorio. NIVEL DE EVIDENCIA: IV.

OBJECTIVE: Describe the early clinical postoperative outcomes, of the first series of patients operated on Robotic Arm-Assisted Total Knee Arthroplasty (TKA) in Latin America. MATERIAL AND METHOD: Retrospective study including 52 patients (53 knees) with advanced symptomatic knee osteoarthritis, consecutively operated on Robotic ArmAssisted TKA (RIO-MAKO) during October 2018 and May 2019 with two months of follow-up. No patients were excluded from the study. The same anesthetic and rehabilitation protocol was followed for all patients. Data were obtained from the clinical files for the following outcomes: Surgical tourniquet time, hospital stay, time to walk, postoperative daily pain [Visual Analog Scale (VAS)], opioid consumption, range of motion (ROM), blood loss, complications, and the attained postoperative mechanical axis. RESULTS: Tourniquet Time: 82 minutes (60­120). Hospital Stay: 4 days (2­12). Postoperative Pain: VAS of 0 (0­10) the same day of surgery, and 0 (0­4) before discharge. The opioid consumption was 0,3 purge (0­6,5) per patient. Time to Walk (Day achieved): 1st day (1­3), forty-five patients (84,9%) walked on their first postoperative day. ROM (Extension-Flexion): progressively increases during the follow up. On the first two-month visits [23 days (13­50)], twenty-one patients (40%) reached a ROM equal or superior to 0­90°, and eleven (20%) presented a maximal functional ROM (0­120°). Blood Loss: Seven patients (13.2%) required a blood transfusion. Complications: one patient (1.89%) presented dehiscence of the arthrotomy closure. No other complications were registered. Postoperative Mechanical Axis: 179.1° (178.2­180). DISCUSSION: The results coincide with the reported evidence from other regions. Robotic-arm assistance may generate reproducible postoperative results. CONCLUSIONS: The early postoperative clinical results of this series of patients operated on Robotic Arm-Assisted TKA show a low pain perception and opioid use, a rapid functional rehabilitation in terms of gait and ROM, and excellent postoperative mechanical alignment. LEVEL OF EVIDENCE: IV.

A census of laparoscopic and robotic urological practice: a survey of minimally invasive surgery department of the Brazilian Society of Urology

ABSTRACT Minimally invasive urologic surgery has been developing in Brazil and now is a routine part of care in many regions and patients with different conditions benefit from it. Training in laparoscopic and robotic surgery has evolved and concerns exist both over the quality of surgical training and the practical effect on results of the urological training. This is an unprecedented study which undertook a census to determinate the current state of laparoscopic and robotic urological practice and to know the mains barriers to adequate practice in Brazil. In august 2017, surveys, consisting of an anonymous questionnaire with 15 questions, were sent via internet to the mailing list of the Brazilian Society of Urology (SBU). With these data, activities related to laparoscopy and robotic surgery of our urologists and the mains difficulties and barriers to practice laparoscopy and robotic surgery were evaluated. In our survey, 413 questionnaires were completed. Majority of the responders were currently working in the southeast region of Brazil (52.1%) and 75.5% of the surgeons performed laparoscopic surgery while, only 12.8%, robotic surgery. The lack of experience on the technique and the lack of equipment were the mains barriers and difficulties for not executing laparoscopic and robotic surgeries, respectively. Proper longitudinal training and access to good equipment in minimally invasive surgery are still barriers for urologists in our country.

A comparison of preliminary oncologic outcome and postoperative complications between patients undergoing either open or robotic radical cystectomy

ABSTRACT Purpose: To compare complications and outcomes in patients undergoing either open radical cystectomy (ORC) or robotic-assisted radical cystectomy (RRC). Materials and Methods: We retrospectively identified patients that underwent ORC or RRC between 2003- 2013. We statistically compared preliminary oncologic outcomes of patients for each surgical modality. Results: 92 (43.2%) and 121 (56.8%) patients underwent ORC and RRC, respectively. While operative time was shorter for ORC patients (403 vs. 508 min; p<0.001), surgical blood loss and transfusion rates were significantly lower in RRC patients (p<0.001 and 0.006). Length of stay was not different between groups (p=0.221). There was no difference in the proportion of lymph node-positive patients between groups. However, RRC patients had a greater number of lymph nodes removed during surgery (18 vs. 11.5; p<0.001). There was no significant difference in the incidence of pre-existing comorbidities or in the Clavien distribution of complications between groups. ORC and RRC patients were followed for a median of 1.38 (0.55-2.7) and 1.40 (0.582.59) years, respectively (p=0.850). During this period, a lower proportion (22.3%) of RRC patients experienced disease recurrence vs. ORC patients (34.8%). However, there was no significant difference in time to recurrence between groups. While ORC was associated with a higher all-cause mortality rate (p=0.049), there was no significant difference in disease-free survival time between groups. Conclusions: ORC and RRC patients experience postoperative complications of similar rates and severity. However, RRC may offer indirect benefits via reduced surgical blood loss and need for transfusion.
