How many procedures are needed to achieve learning curve of Millin simple laparoscopic prostatectomy?

BACKGROUND: Aim of our study was to evaluate learning curve of the Millin simple prostatectomy analyzing three expert laparoscopic surgeons. METHODS: Learning curve of 3 expert laparoscopic surgeons with excellent radical prostatectomy training was evaluated. Surgeon 1 had more than 20 years of experience, while other surgeons had 10 years of experience. The first 45 procedures of the surgeons were considered for analysis. The cumulative sum (CUSUM) technique, one of the methods developed to monitor the performance and quality of the industrial sector, was adopted to analyze learning curves. The variables included to evaluate learning curve of the surgeons were: operative time (OT), hospitalization (HO) and complication rate. RESULTS: Overall 135 patients were included in the analysis. Median age was 68 (64/74), median prostate volume was 83 (75/97), median Qmax 9 mL/s (6/11) and median IPSS=20 (18/22). Complications included: 9/135 (7%) transfusion, 4/135 (3%) Urinary retention, 3/135 (2%) fever, 1/35 (<1%) reintervention and 1/135 (<1%) conversion. Surgeon 1 presented a lower median operative time when compared to surgeon 2 and 3. No significant differences were recorded in terms of hospitalization, blood loss and transfusion rate as well as postoperative outcomes. According to the CUSUM analysis the number of procedures needed to achieve a plateau in surgical time is 10/15 procedures. CONCLUSIONS: According to our results 15 procedures are needed to reach a plateau in surgical time for trained laparoscopic surgeons.

Laparoscopic simple prostatectomy: a large single-center prospective cohort study.

BACKROUND: The aim of our study was to analyze outcomes and safety of laparoscopic simple prostatectomy (LSP) in a high-volume center. METHODS: A consecutive series of men with lower urinary tract symptoms and large prostates (>80 cc) prospectively enrolled between November 2015 and December 2017 in one center. All patients underwent laparoscopic simple prostatectomy. Outcomes were evaluated considering the trifecta favorable outcome which was defined as a combination of the following items: 1) no perioperative complications; 2) postoperative IPSS <8; 3) postoperative Qmax >15 mL/s. Complications were evaluated according to the modified Clavien classification system. Univariate and multivariate binary logistic regression was performed to identify predictors of a positive trifecta outcome. RESULTS: Overall 272 patients were enrolled. At three months after surgery median IPSS total score was 4 (IQR: 3-7), median IPSS QoL was 1 (IQR:1-2), median prostate-specific antigen was 0.53 (IQR: 0.33-1.00) ng/ml and median Qmax was 23 (IQR: 17-30) mL/s. All these parameters improved statistically when compared to baseline (P<0.001). The overall complication rate was 21% however most of the complications were low grade complications according to modified Clavien-Dindo classification (grade ≤2). Overall, 68% of the patients presented a positive trifecta outcome. On multivariate analysis only preoperative hemoglobin and hospital stay were confirmed predictors of positive trifecta outcome. CONCLUSIONS: LSP represents a safe and effective procedure in the treatment of large adenomas. Although RCTs are needed before reaching definitive conclusions, LSP is a promising technique for patients with LUTS and large prostates.

Laparoscopic simple prostatectomy vs bipolar plasma enucleation of the prostate in large benign prostatic hyperplasia: a two-center 3-year comparison.

PURPOSE: To compare surgery outcomes and safety of button bipolar enucleation of the prostate vs laparoscopic simple prostatectomy in patients with large prostates (> 80 g) in a two-center cohort study. METHODS: All patients with lower urinary tract symptoms due to benign prostatic enlargement (Prostate volume > 80 cc) undergoing button bipolar enucleation of the prostate (BTUEP) or laparoscopic simple prostatectomy (LSP) in two centers were enrolled. Data on clinical history, physical examination, urinary symptoms, uroflowmetry and prostate volume were collected at 0, 1, 3 6, 12, 24 and 36 months. Early and long-term complications were recorded. RESULTS: Overall, 296 patients were enrolled. Out of them, 167/296 (56%) performed a LSP and 129/296 (44%) performed a BTUEP. In terms of efficacy both procedures showed durable results at three years with a reintervention rate of 8% in the LSP group and of 5% in the BTUEP group. In terms of safety, BTUEP and LSP presented similar safety profiles with a 9% of transfusion rate and no major complications. CONCLUSION: LSP and BTUEP are safe and effective in treating large-volume adenomas with durable results at three years when performed in experienced centers.

[Impact of predictive models and decision making in prostate cancer: An integral debate]. / Impacto de los modelos predictivos y la toma de decisiones en cáncer de próstata: un debate integral.

OBJECTIVES: To review the various methods to predict the risk of having prostate cancer, or that localized disease may be cured or progress after a given treatment. METHODS: We performed a review of the various mathematic models known for the probability analysis of the event, with a critical analysis of weaknesses and strengths of each method. In a Medline update we review the most relevant papers referred to diagnosis and management of localized prostate cancer in its diagnosis and management sides, as well as the probability of developing metastatic disease and to die. RESULTS: There are multiple methods and models to predict the various events in a patient candidate to diagnosis of prostate cancer, as well as to analyze the possibilities of success of a specific treatment, in many cases with an important exactness. We emphasize the heterogeneity in the methods, data and variables used for the analysis, basically about retrospective studies. Many of the most sophisticated methods, Neural Network or cart, do not present greater exactness than classic methods like logistic regression. CONCLUSIONS: Predictive models are an important element for decision making in usual clinical practice, favoring the decision of a diagnosis or certain treatment is not taken in a random manner and therefore it is taken following scientific criteria. Waiting for more precise methods, we have to know no method is perfect, and therefore it is an important tool, which should not by pass personal knowledge or the experience of a specific working group.

Impacto de los modelos predictivos y la toma de decisiones en cáncer de próstata: un debate integral / No disponible

OBJETIVO: Hacer una revisión de los diferentes métodos para predecir el riesgo de padecer un cáncer de próstata o que la enfermedad localizada pueda ser curada o progrese después de un tratamiento concreto. MÉTODOS: Realizamos una revisión de los diferentes modelos matemáticos conocidos para el análisis de probabilidad del evento, con un estudio crítico de debilidades y fortalezas de cada uno de estos métodos. En una actualización del Medline, revisamos los diferentes trabajos más relevantes referidos al diagnóstico y manejo del cáncer de próstata localizado en sus vertientes de diagnóstico y tratamiento, así como las posibilidades de desarrollar enfermedad metastásica o exitus. RESULTADOS: Existen múltiples métodos y modelos para predecir los diferentes eventos en pacientes candidatos a diagnóstico de cáncer de próstata, así como para analizar posibilidades de éxito de un tratamiento concreto, en muchos casos con una importante exactitud. Destaca la heterogeneidad en los métodos empleados, datos y variables utilizadas para los análisis, básicamente sobre estudios retrospectivos. Muchos de los métodos más sofisticados, Neural Network o Cart, no presentan exactitudes mayores que los métodos clásicos como la regresión logística. CONCLUSIONES: Los modelos predictivos son un elemento importante para la toma de decisiones en la práctica clínica habitual, favoreciendo que la decisión de un diagnóstico o un determinado tratamiento no se haga de forma aleatoria y por tanto siguiendo un criterio científico. En espera de desarrollo de métodos más precisos, hemos de saber que ningún modelo es perfecto y por tanto, es una herramienta importante, que no debe dejar de lado el conocimiento personal o la experiencia en un grupo de trabajo concreto(AU)

Signet-ring cell adenocarcinoma of the bladder: case series between 1990-2009.

OBJECTIVES: To present a revision on the signet-ring cell bladder adenocarcinomas found in our department. METHODS/RESULTS: We reviewed all the transurethral resections of the bladder (TURB) performed between 1990 and 2009 finding 9 cases of primary signet ring cell adenocarcinomas (4 pure and 5 mixed). Eight were male and one female, with ages between 39 and 82 years. Definitive treatment was radical cystectomy with Bricker's urinary diversion in four patients, cysctectomy with Mainz's II diversion in one patient and palliative management with TURB in three cases and percutaneous nephrostomy in the remaining case. We used adyuvant chemotherapy in three cases. Only two patients were alive at the time of the study. Mean survival was 327 days for pure tumors and 586 for the mixed ones. CONCLUSIONS: Signet-ring cell primary adenocarcinoma of the bladder is an uncommon type of tumor, with worse prognosis than transitional cell cancer. It is important to discard other possible metastatic origins(like stomach, prostate, lung, or ovary) because the management will be different. Radical cystectomy is the treatment of choice, with adyuvant chemotherapy if possible. Five year survival is less than 11%

Adenocarcinoma vesical de células en anillo de sello: revisión de nuestros casos entre 1990-2009 / Signet-ring cell adenocarcinoma of the bladder: case review between 1990-2009

OBJETIVOS: Presentar una revisión de los adenocarcinomas primarios de vejiga de células en anillo de sello de nuestro servicio. MÉTODO/RESULTADO: Revisamos las RTU de vejiga realizadas entre 1990 y 2009 encontrando 9 casos de tumores primarios de vejiga de células en anillo de sello (4 puros y 5 mixtos).8 eran varones y 1 mujer, con edades comprendidas entre los 39 y los 82 años. Tratamiento definitivo consistió en cistectomía radical con derivación tipo Bricker en cuatro de los pacientes, cistectomía con derivación Mainz II en otro de ellos y paliativo en los cuatro restantes con RTU en tres casos y NPC paliativas en otro. Empleamos quimioterapia adyuvante en 3 casos. Sólo dos de los pacientes estaban vivos en el momento del estudio. La media de supervivencia fue de 327 días para los tumores puros y de 586 para los mixtos.CONCLUSIÓN: Los adenocarcinomas primarios de vejiga con células en anillo de sello son unos tumores poco frecuentes, con peor pronóstico que los de células transicionales. Es importante que descartemos los posibles orígenes metastásicos (de estómago, próstata, ovario, pulmón) ya que el manejo a seguir será distinto en función de la localización del tumor primario. El tratamiento de elección en los primarios de vejiga es la cistectomía radical, con quimioterapia adyuvante en los casos que sea posible. La supervivencia a 5 años es < al 11%(AU)

[Inguinal ureteral hernia: a clinical case]. / Hernia ureteral inguinal: caso clínico.

SUMMARY OBJECTIVES: To describe a clinical case of ureteral inguinal hernia and to comment briefly about the topic. METHODS: 80 year-old patient with, hypertension, left inguinal hernia surgery, right hemicolectomy for colon adenocarcinoma and cholecystectomy. Intravenous urogram casually found that the right ureter was leaving the abdominal cavity though the right inguinal duct and then returned to the abdomen. RESULTS: CT scan confirmed the diagnosis. Due to the advanced age of the patient, comorbidities and the absence of symptoms, conservative treatment was decided. CONCLUSIONS: Ureteral hernias through the inguinal duct are uncommon. There are 2 types: paraperitoneal and extraperitoneal. The most common is the paraperitoneal (80%) which is accompanied by hernia sac and can appear with other abdominal organs. The extraperitoneal often accompanied by retroperitoneal fat. Both types of hernias are usually indirect. Treatment is usually herniorrhaphy.
