Aplicación de protocolos ERAS (Enhanced Recovery After Surgery) en pacientes cistectomizados: el camino hacia la estandarización. Una revisión sistemática / Implementation of ERAS (Enhanced Recovery After Surgery) protocols for radical cystectomy patients: The pathway to standardization. A systematic review

CONTEXTO: El desarrollo de protocolos ERAS (Enhanced Recovery After Surgery) en pacientes sometidos a cirugía mayor ha aportado beneficios perioperatorios en diversas disciplinas. En urología, su principal aplicación se centra en pacientes sometidos a cistectomía radical. OBJETIVO: Revisión sistemática de la literatura disponible de protocolos ERAS aplicados a pacientes intervenidos de cistectomía radical, tanto a nivel de resultados perioperatorios como en el análisis de su implementación. Adquisición de la evidencia: Se realizó búsqueda bibliográfica en base de datos electrónicas Pubmed, Embase, Cochrane y Scopus, utilizando los términos «Cystectomy», «Enhanced Recovery After Surgery» y «Fast-Track». Se seleccionaron estudios aleatorizados y no aleatorizados que comparasen la implementación de un protocolo ERAS en pacientes sometidos a cistectomía radical frente a un protocolo tradicional. Síntesis de la evidencia: Se identificaron 869 artículos; 25 fueron seleccionados para el análisis final: 22 estudios no aleatorizados y 3 aleatorizados. No se detectaron diferencias en cuanto a características demográficas entre los distintos estudios. Se identificaron diferencias estadísticamente significativas a favor del protocolo ERAS en tiempo de estancia hospitalaria, tasa de complicaciones mayores, tiempo a primera deambulación y recuperación intestinal. En el análisis de protocolos se detectó una alta variabilidad, tanto en número de ítems como en método de implementación. CONCLUSIONES: El carácter multidisciplinar y el número de ítems de los protocolos ERAS conlleva una alta heterogeneidad en su implementación. Se requieren más estudios aleatorizados, estandarización a la hora de reportar y analizar resultados, así como un análisis sistemático de la adherencia posterior para aumentar la comparabilidad entre grupos

CONTEXT: The development of ERAS (Enhanced Recovery After Surgery) protocols in patients undergoing major surgery has brought perioperative benefits in several disciplines. Its main application in urology is focused on patients undergoing radical cystectomy. OBJECTIVE: Systematic review of the available literature on ERAS protocols applied to patients undergoing radical cystectomy in terms of perioperative outcomes as well in the analysis of their implementation. Evidence acquisition: A bibliographic search was conducted in the electronic databases PubMed, Embase, Cochrane and Scopus, using the terms «Cystectomy», «Enhanced Recovery After Surgery» and «Fast-Track». Randomized and non-randomized studies that compared the implementation of an ERAS protocol versus a traditional protocol in patients undergoing radical cystectomy were selected. Evidence synthesis: 869 articles were identified; 25 were selected for final analysis: 22 non-randomized and 3 randomized studies. No differences were observed in terms of demographic characteristics between studies. Statistically significant differences were identified in favor of the ERAS protocol: length of hospital stay, major complication rate, time to first ambulation and return of bowel function. In the analysis of protocols, a high variability was detected in the number of items and in the implementation method. CONCLUSIONS: The multidisciplinary nature and the number of items of the ERAS protocols imply a high heterogeneity in their implementation. Further randomized studies, standardized reporting and analyzing results, as well as a systematic analysis of subsequent adherence are required to increase comparability between groups

Etiology of Fournier gangrene as a prognostic factor in mortality: Analysis of 121 cases. / Etiología de la gangrena de Fournier como factor pronóstico de mortalidad: análisis de 121 casos.

OBJECTIVE: Evaluate the origin of Fournier gangrene (FG) as a prognostic factor of morbidity and mortality. MATERIAL AND METHODS: Patients who came to our clinic with a diagnosis of FG from 2010 to 2017 were included retrospectively. Patients were categorized depending on the origin of the infection. Three severity factors were determined in each group: days of hospital stay, the FG severity index, and mortality. Logistic regression test was performed to analyze the data. RESULTS: Of the 130 patients evaluated, the origin was established in 121 based on the clinical history and radiological and surgical findings. Thirty-five patients had an intestinal origin with a mortality of 20.68%, 46 patients had a testicular origin with a mortality of 2.22%, 12 patients had a urinary origin with a mortality of 0%, and 28 patients with a cutaneous origin with a mortality of 16.6%. The testicular origin was the most frequent (38%) in addition to presenting a lower hospital stay, a lower FG severity index, and a lower mortality than those with an intestinal origin (P=.022). CONCLUSIONS: The origin of the infection has a significant prognostic value in the mortality of the patient.

Valoración objetiva de la continencia urinaria precoz mediante el análisis y la visualización de variables intraoperatorias de prostatectomías radicales robóticas con un editor de vídeos / Objective assessment of early urinary continence by analysis and visualisation of intraoperative variables of radical robotic prostatectomies with a video editor

Introducción: La IU tras PR es uno de los factores con mayor impacto en la calidad de vida de los pacientes y en el gasto sanitario asociado. La definición de IU es muy variable en la literatura. De igual modo, son múltiples los factores predictores estudiados que influyen en la recuperación de la continencia posquirúrgica, siendo los más importantes los factores intraoperatorios. Material y métodos: Estudio retrospectivo y observacional, desde septiembre del 2008 hasta marzo del 2015. Se realiza el análisis de factores intraoperatorios mediante la visualización, con un editor de vídeos, de 148 pacientes tratados mediante prostatectomía radical asistida por robot, junto con otros factores perioperatorios asociados a la continencia y descritos en la literatura. Valoramos la continencia mediante cuestionarios ICQ, pérdidas urinarias contabilizadas con absorbentes y entrevista clínica en el primer, el tercer y el sexto mes, y al año de la cirugía. Definimos continencia como el no uso de absorbente o uno como protección social o ICQ ≤ 7. Analizamos mediante regresión logística binaria y lineal qué relación tienen las variables intraoperatorias y perioperatorias sobre la continencia urinaria medidas el primer, el tercer y el sexto mes, y al año de la cirugía, y sobre la estabilidad de la continencia. Resultados: En nuestro estudio el 72,9% de los pacientes conseguían estar continentes al año de la cirugía, con un tiempo medio de estabilización de la misma a los 4,3 meses. En nuestro análisis de regresión logística binaria de las variables intraoperatorias, no hemos encontrado una relación significativa con la variable continencia, analizadas durante el primer año. En el análisis de regresión logística lineal hemos encontrado que las suturas libres de tensión tienen un efecto directo positivo (p ≤ 0,05) sobre el tiempo de estabilidad de la continencia, al igual que las pérdidas urinarias medidas en el primer mes de la cirugía. Conclusión: En conclusión, en nuestro estudio encontramos que aquellas suturas libre de tensión pueden ayudar a la estabilidad precoz de la continencia. No hemos encontrado otros predictores intraoperatorios que influyan en la continencia urinaria. Las pérdidas urinarias medidas en el primer mes se relacionan con la recuperación precoz de la continencia

Introduction: UI after RP is a factor that has a major impact on patients' quality of life and the associated healthcare costs. The definition of UI is very variable in the literature. Similarly, a great many predictors have been studied that affect recovery of continence after surgery, the most important of which are intraoperative. Material and methods: a retrospective and observational study performed between September 2008 and March 2015. We studied intraoperative factors through visualisation using a video editor of 148 patients who underwent robot-assisted radical prostatectomy, together with other perioperative factors associated with continence, and described in the literature. We assessed continence through ICQ questionnaires, urinary loss calculated by pad count, and clinical interview in the first, third, sixth month and at one year after surgery. We defined continence as not having to use a pad or using a pad for protection socially, or an ICQ ≤ 7. We used binary and lineal logistic regression analysis to study the relationship between the intraoperative and perioperative variables on urinary continence measured at the first, third, sixth month and one year after the operation, and on continence stability. Results: In our study, 72.9% of the patients were continent at one year after surgery with a mean continence stabilisation time at 4.3 months. In our lineal logistic regression analyses we found no significant relationship with the continence variable analysed during the first year. In the lineal logistic regression analysis we found that tension-free sutures had a direct positive effect (P≤.05) on the stability time of continence, as well as the urinary losses measured in the first month after surgery. Conclusion: In conclusion, we found in our study that the tension-free sutures were able to help towards early stability of continence. We found no other intraoperative predictors that influenced urinary continence. The urinary losses measured in the first month related to early recovery of continence

[Comparative study between the Fisk-Fernández and Matti-Russe techniques for the management of carpal scaphoid pseudoarthrosis]. / Estudio comparativo entre las técnicas de Fisk-Fernández y Matti-Russe para el manejo de las seudoartrosis de escafoides carpal.

OBJECTIVE: To assess the treatments for carpal scaphoid pseudoarthrosis with the Matti-Russe and Fisk-Fernández techniques taking as a reference the most widely used technique, i.e., fixation with Kirschner wire with a corticocancellous bone graft. The bone healing rates reported by different series using this procedure do not exceed 70%, especially in cases in which the proximal scaphoid fragment is compromised. The healing rate with the Fisk-Fernández technique was 90-97%. Twelve males and one female were operated on at the National Rehabilitation Institute; the age range was 18-58 years (mean age 32 years). Thirteen patients had bone healing after week 12. CONCLUSION: This is an easy, quick, and functional procedure, but patient cooperation is required for rehabilitation and return to work.

[Scrotal mass presenting as giant urethral diverticulum]. / Masa escrotal como presentación de divertículo uretral gigante.

Urethral diverticulum in the male is a rare entity that may be congenital or acquired. They are common in paraplegic patients, who are prone to developing this disorder on an acquired basis because of prolonged catheterization. The most common diseases in patients with spinal cord injury are stricture, fistula and diverticula. Patients with diverticula typically present with symptoms of urinary incontinence, dysuria, perineal pain, or a mass on the ventral aspect of the genitalia or perineum. Treatment of choice is always surgical and a complete extirpation should be performed.

Enucleación prostática con láser holmium / Prostatic enucleation with holmium laser

Objetivo: La hipertrofia prostática afecta a partir de los 40 años a un porcentaje creciente de varones, aumentando este con la edad, actualmente contamos con una nueva arma terapéutica, el láser Holmium. Método: Recogemos de manera retrospectiva los datos obtenidos de forma retrospectiva de los 300 enfermos intervenidos mediante HoLEP prostático en nuestro centro. Resultados: Obtenemos: una estancia media hospitalaria de 1,8 días (Rango 1-15 días, mediana 1,8), un tiempo medio de cateterismo de 30,6h (Rango 12-312, Mediana 30,3), el tiempo quirúrgico total desde que el enfermo entra hasta que sale del quirófano es de 75 min. (Rango 38-150, Mediana 71), El flujo máximo es de 24,7 ml/seg a 6 meses y de 23,9 ml/seg a 12 meses. El rendimiento quirúrgico, los gramos resecados por minuto es de 0,48 en el grupo completo. Observamos una variación en los datos que afecta a los 20 primeros casos, con un empeoramiento de los resultados en este grupo Conclusiones: en nuestra opinión la enucleación con láser de Holmium es un método adecuado que garantiza unos resultados óptimos, perfectamente comparables a los obtenidos mediante técnicas quirúrgicas endoscópica clásicas y cirugía abierta, con un número de complicaciones bajo y que beneficia al enfermo al disminuir la necesidad de trasfusiones, el tiempo de sondaje vesical y de estancia hospitalaria, en contrapartida, presenta una curva de aprendizaje en torno a 20 procedimientos, en la que se pueden presentar complicaciones que desanimen al cirujano y que paralicen el proyecto de implantación de la técnica en un centro, al tener procedimientos fáciles y asequibles a su alcance ya establecidos (AU)

Objectives: Benign prostatic hyperplasia (BPH) affects a growing percentage of males over the age of 40 years, increasing with age. Currently, we have a new therapeutic tool available: the holmium laser. Methods: We retrospectively collected data of 300 patients undergoing holmium laser enucleation of the prostate (HoLEP) in our center. Results: The results are: mean hospital stay 1,8 days (range 1-15 days, median 1,8); mean bladder catheter time 30.6 hours (range 12-312, median 30.3), total operative room time 75 minutes (range 38-150, median 71), maximal flow rate at six months 24.7 ml/sec. and 23.9 ml/sec. at 12 months. Surgical performance, number of grams resected per minute, is 0.48 for the whole group. We observed a variation in data from the first 20 cases, with worse results in this group. Conclusions: In our opinion holmium laser enucleation is an adequate method that the guarantees optimal results, comparable to those obtained with classic endoscopic and open surgical techniques, with a low rate of complications, which benefits the patient by diminishing the need for transfusions, catheterization time, and hospital stay; conversely, it has a learning curve of around 20 procedures, which may be associated with complications that may discourage the surgeon and stop the project of technique implementation in a center, having easy, accessible, established alternative procedures (AU)

Masa escrotal como presentación de divertículo uretral gigante / Scrotal mass presenting as giant urethral diverticulum

El divertículo uretral en el varón es una entidad rara que puede ser congénita o adquirida. Son comunes en pacientes parapléjicos que son propensos a desarrollar este problema de forma adquirida debido a cateterizaciones prolongadas. Las enfermedades mas frecuentes en pacientes lesionados medulares son estenosis, fístulas y divertículos. Pacientes con divertículos típicamente se presentan con síntomas de incontinencia urinaria, disuria, dolor perineal o una masa genital o en periné. El tratamiento de elección es siempre quirúrgico y debería realizarse una extirpación completa del mismo (AU)

Prospective randomized trial of 3 antiseptic solutions for prevention of catheter colonization in an intensive care unit for adult patients.

OBJECTIVE: To compare the effectiveness for prevention of central venous and arterial catheter colonization of 3 skin antisepsis with 1 of 3 antiseptic solutions: 10% aqueous povidone iodine (aqueous PI), 2% aqueous chlorhexidine gluconate (aqueous CG), and 0.5% alcoholic chlorhexidine gluconate (alcoholic CG). DESIGN: Prospective, randomized controlled trial. SETTING: Intensive care unit in a teaching hospital. METHODS: Patients were randomly assigned to 1 of the 3 skin antisepsis groups. The distal tips of catheters were semiquantitatively cultured when the catheters were no longer necessary or if there was a suspicion of catheter-related infection. Rates of catheter colonization, catheter-related sepsis, and catheter-related bacteremia were compared among the 3 groups. RESULTS: A total of 631 catheters were included in the study (194 from the aqueous PI group, 211 from the aqueous CG group, and 226 from the alcoholic CG group). The incidence of catheter colonization was significantly lower in the alcoholic CG than in the aqueous PI group (14.2% vs 24.7%; relative risk, 0.5 [95% confidence interval, 0.3-0.8; P < .01]); it was also significantly lower in the aqueous CG group than in the aqueous PI group (16.1% vs 24.7%; relative risk, 0.6 [95% confidence interval, 0.4-0.9; P = .03]). There were no significant differences between the aqueous CG and the alcoholic CG groups. Incidences of catheter-related bacteremia were similar for all 3 groups. The aqueous and alcoholic CG solutions were superior to the aqueous PI solution in preventing catheter colonization due to gram-positive bacteria. CONCLUSIONS: The aqueous and alcoholic CG solutions for cutaneous antisepsis were similarly effective in preventing colonization of central venous catheters and arterial catheters. Both had significantly lower incidences of colonization than did the aqueous PI solution; this effect seems to be related to the CG solutions' more efficacious prevention of colonization with gram-positive bacteria.

[Dual-chamber pacemakers in obstructive hypertrophic cardiomyopathy: gradient variation with stress echocardiography]. / Marcapasos bicameral en la miocardiopatía hipertrófica obstructiva: variación del gradiente con ecocardiografía de estrés.

INTRODUCTION: Permanent cardiac pacing with a dual chamber pacemaker has become a valid alternative in treatment of patients with obstructive hypertrophic cardiomyopathy and refractory symptoms to pharmacological treatment, with a significant decrease of left ventricular outflow tract gradient. AIM: To assess any modification of the gradient with dobutamine stress echocardiography. PATIENTS AND METHODS: We study 10 patients with obstructive hypertrophic cardiomyopathy and angina and/or dyspnea refractory to customary pharmacological treatment. A dual chamber pacemaker had been implanted 3-6 months previously. A dobutamine stress echocardiography was performed, beginning with a 10 microgram/kg/min infusion, with increases of 10 micrograms each 3 minutes until a maximum of 40. Modification of subaortic gradient, severity of systolic anterior motion of mitral valve (SAM, degree 0-3/3) and severity of mitral regurgitation (degree 0-4/4) were assessed. RESULTS: Subaortic gradient decreased in all patients after pacemaker implantation (90 +/- 15 vs 20 +/- 10 mmHg; p < 0.001). With stress echocardiography the gradient increased in all patients (20 +/- 10 to 101 +/- 13 mmHg; p < 0.001). After implant there were only two patients with a +1 SAM, while during stress echocardiography SAM developed in all patients in +2 or +3 degree. Three patients had +1 mitral regurgitation after pacemaker implantation but during stress echocardiography 2-4/4 mitral regurgitation developed in all patients. CONCLUSIONS: Permanent dual chamber pacing decreased left ventricular outflow tract gradient in patients with obstructive hypertrophic cardiomyopathy, but during dobutamine stress echocardiography obstruction echocardiographic signs appeared.
