Perioperative, Oncological, and Functional Outcomes Between Robot-Assisted Laparoscopic Prostatectomy and Open Radical Retropubic Prostatectomy: A Randomized Clinical Trial.

PURPOSE: Limited high-quality studies have compared robot-assisted laparoscopic prostatectomy (RALP) vs open retropubic radical prostatectomy. We sought to compare their postoperative outcomes in a randomized setting. MATERIALS AND METHODS: In a single center, 354 men with newly diagnosed prostate cancer were assessed for eligibility; 342 were randomized (1:1). The primary outcome was 90-day complication rates. Functional outcomes and quality of life were assessed over 18 months, and oncological outcomes, biochemical recurrence-free survival, and additional treatment over 36 months. RESULTS: From 2014 to 18, 327 patients underwent surgery (retropubic radical prostatectomy = 156, RALP = 171). Complications occurred in 27 (17.3%) vs 19 (11.1%; P = .107). Patients undergoing RALP experienced lower median bleeding (250.0 vs 719.5 mL; P < .001) and shorter hospitalization time. Urinary EPIC (Expanded Prostate Cancer Index Composite) median scores were better for RALP over 18 months, with higher continence rate at 3 months (80.5% vs 64.7%; P = .002), 6 months (90.1% vs 81.6%; P = .036) and 18 months (95.4% vs 78.8%; P < .001). Sexual EPIC and Sexual Health Inventory for Men median scores were higher with RALP up to 12 months, while the potency rate was superior at 3 months (23.9% vs 5.3%; P = .001) and 6 months (30.6% vs 6.9%; P < .001). Quality of life over the 18 months and oncological outcomes over 36 months were not significantly different between arms. CONCLUSIONS: Complications at 90 days were similar. RALP showed superior sexual outcomes at 1 year, improved urinary outcomes at 18 months, and comparable oncological outcomes at 36 months.

Impact of Prostate-Specific Membrane Antigen Positron Emission Tomography/Computed Tomography on the Therapeutic Decision of Prostate Carcinoma Primary Staging: A Retrospective Analysis at the Brazilian National Public Health System.

BACKGROUND: Prostate cancer (PCa) is the most common malignant tumor in males and conventional imaging does not provide accurate primary staging. Prostate-specific membrane antigen (PSMA) positron emission tomography (PET) presents superior performance and strongly affects therapeutic choice. OBJECTIVE: The aim of this study was to evaluate the impact of PSMA PET, compared with conventional imaging methods, on the therapeutic approach in primary staging scenarios in patients with PCa treated at the Brazilian National Public Health System. METHODS: Overall, 35 patients diagnosed with PCa were evaluated using PSMA after conventional staging imaging with multiparametric magnetic resonance (MMR) and/or total abdominal computed tomography (CT) scan and bone scintigraphy (BS). The PCa extension identified by PET was compared with conventional imaging; staging changes and the management impact were then determined. PET comparison with conventional imaging, staging, and decision-making changes was analyzed using descriptive statistics. RESULTS: PET revealed local disease (LD) in 15 (42.9%) patients, seminal vesicle invasion (SVI) in 5 (14.3%) patients, pelvic nodal impairment (PNI) in 7 (20%) patients, pelvic and distant nodes in 3 (8.6%) patients, pelvic nodes and bone metastasis in 4 (11.4%) patients, and pelvic and distant nodes and bone metastasis in 1 (2.8%) patient. Staging changes were observed in 60% of patients, with downstaging predominance (76.2%). Volume increase was identified in 11 (31.4%) patients (only 4 related to upstaging, 36.4%). The board changed management decisions for 60% of the patients. The main limitations of this study were the sample size and its retrospective nature. CONCLUSIONS: PSMA findings changed the management decisions in more than half of the patients, which made the majority eligible for locoregional treatment and avoided unnecessary procedures in the systemic disease scenario.

Risk factors for mortality in blunt abdominal trauma with surgical approach.

OBJECTIVE: identify risk factors for mortality in patients who underwent laparotomy after blunt abdominal trauma. METHODS: retrospective study, case-control, which were reviewed medical records of blunt trauma victims patients undergoing laparotomy, from March 2013 to January 2015, and compared the result of the deaths group with the group healed. RESULTS: of 86 patients, 63% were healed, 36% died, and one patient was excluded from the study. Both groups had similar epidemiology and trauma mechanism, predominantly young adults males, automobilistic accident. Most cases that evolved to death had hemodynamic instability as laparotomy indication - 61% against 38% in the other group (p=0.02). The presence of solid organ injury was larger in the group of deaths - 80% versus 48% (p=0.001) and 61% of them had other associated abdominal injury compared to 25% in the other group (p=0.01). Of the patients who died 96% had other serious injuries associated (p=0.0003). Patients requiring damage control surgery had a higher mortality rate (p=0.0099). Only one of 18 patients with isolated hollow organ lesion evolved to death (p=0.0001). The mean injury score of TRISS of cured (91.70%) was significantly higher than that of deaths (46.3%) (p=0.002). CONCLUSION: the risk factors for mortality were hemodynamic instability as an indication for laparotomy, presence of solid organ injury, multiple intra-abdominal injuries, need for damage control surgery, serious injury association and low index of trauma score.

RESUMOObjetivo:identificar fatores de risco para óbito em pacientes submetidos à laparotomia exploradora após trauma abdominal contuso.Métodos:estudo retrospectivo, caso-controle, no qual foram revisados prontuários dos pacientes vítimas de trauma contuso submetidos à laparotomia. Foram avaliados: variáveis epidemiológicas, mecanismo de trauma, lesões anatômicas das vísceras abdominais, lesões associadas, necessidade de operação para controle de danos reoperação e desfecho.Resultados:dos 86 pacientes, 63% foram curados, 36% foram a óbito e um paciente foi excluído do estudo. Ambos os grupos possuíam epidemiologia e mecanismo de trauma semelhantes, predominantemente adultos jovens do sexo masculino, vítimas de acidente automobilístico. A maioria dos casos que evoluíram a óbito teve instabilidade hemodinâmica como indicação de laparotomia - 61% contra 38% do outro grupo. A presença de lesão de víscera maciça foi maior no grupo óbitos - 80% vs. 48%, e 61% destes tinham outra lesão abdominal associada contra 25% dos curados. Dos pacientes que faleceram, 96% apresentavam lesões graves associadas. Pacientes que necessitaram de cirurgia de controle de danos tiveram maior taxa de mortalidade. Apenas um de 18 pacientes com lesão de víscera oca isolada evoluiu a óbito. A média do escore de trauma TRISS dos curados (91,7%) foi significativamente maior do que a dos óbitos (46,3%).Conclusão:os fatores de risco para óbito encontrados para vítimas de trauma abdominal fechado que necessitam de laparotomia exploradora são: instabilidade hemodinâmica como indicação para laparotomia, presença de lesão de víscera maciça, múltiplas lesões intra-abdominais, necessidade de cirurgia de controle de danos, lesões graves associadas e índice de trauma baixo.
