ABSTRACT

Introducción y objetivo: El abordaje mediante cirugía mínimamente invasiva de la patología de la glándula suprarrenal es el más extendido hoy en día, en donde la retroperitoneoscopia ocupa un lugar a tener muy en cuenta; sin embargo, la evolución de estas técnicas hacia abordajes todavía menos invasivos a través de puerto único es anecdótica.La finalidad de este trabajo es describir nuestra experiencia inicial en cirugía retroperitoneoscópica por puerto único (SPORS) de la glándula suprarrenal centrándonos en los datos perioperatorios y dolor postoperatorio.Material y métodosRecogimos y analizamos los datos demográficos y operatorios de una serie de pacientes tratados mediante suprarrenalectomía mediante SPORS. Todos los procedimientos se realizaron mediante una única incisión subcostal de 3-4cm a través de un puerto multicanal. Se recogen diferentes datos quirúrgicos como tiempo operatorio, sangrado, estancia o presencia de complicaciones. Empleamos la escala visual analógica (EVA) para la valoración del dolor postoperatorio.ResultadosEntre diciembre del 2018 y agosto del 2020, 6 pacientes con diferentes patologías suprarrenales fueron intervenidos en nuestro Departamento de forma consecutiva por el mismo cirujano mediante SPORS. Todas las cirugías se realizaron sin requerir colocación de trocares accesorios o reconversión a cirugía abierta. El tiempo medio de las intervenciones fue de 91,6±16,3 min, con un sangrado <150ml, una estancia media de 35,8±13,3 h y un dolor postoperatorio analizado EVA ≤ 3 (mediana de 0,5). El tamaño medio de las piezas fue de 57,8±18mm. No se reportó ninguna complicación según la escala Clavien-Dindo.


Introduction and objective: The minimally invasive surgical approach to adrenal gland pathology is the most widely used nowadays, and retroperitoneoscopy occupies a relevant place. However, the evolution of these techniques towards even less invasive surgery through single-port access is anecdotal. The aim of this work is to describe our initial experience in single-port retroperitoneoscopic surgery (SPORS) of the adrenal gland focusing on perioperative data and postoperative pain.Material and methodsWe collected and analyzed the demographic and operative data of a series of patients undergoing adrenalectomy through SPORS. All procedures were performed through a single 3-4cm subcostal incision with a multichannel port. Surgical data such as operative time, bleeding, length of stay and presence of complications were collected. We used the visual analog scale (VAS) for postoperative pain assessment.ResultsFrom December 2018 to August 2020, 6 patients with different types of adrenal pathology underwent consecutive surgeries in our Department by the same surgeon using SPORS. All surgeries were performed without requiring accessory trocar placement or reconversion to open surgery. The mean operative time was 91.6±16.3minutes, with <150mL bleeding, mean length of stay of 35.8±13.3hours and postoperative pain of VAS ≤3 (median 0.5). The mean size of specimens was 57.8±18mm. No complications were reported according to the Clavien-Dindo scale. (AU)

ABSTRACT

OBJECTIVE: Transperitoneal laparoscopic adrenalectomy (TLA) is considered the treatment of choice for small and benign adrenal tumors. In the recent years, posterior retroperitoneoscopic adrenalectomy (PRA) has gained popularity due to its advantages over TLA, presenting a shorter surgical time and a faster recovery without increasing complications. Conversely, a greater learning curve is considered because the use of a different and unusual surgical field. MATERIAL AND METHODS: Our objective is to describe the PRA technique to ass our initial experience evaluating its feasibility, safety and effectiveness in a prospective series of patients. A total of 11 (9 left and 2 right) PRA performed between March 2017 and February 2020 were analyzed. RESULTS: Median age was 55 (36-65) years with a median BMI of 25.69 (20.8-34.5) Kg/m2. 54.55% had ASA≥3. 63.37% of adrenal tumors were hormonally functional. The tumor mean size was 4 cm (0.6-8) and cortical adenoma was the predominant pathological anatomy (72.72%). No pheochromocytoma was operated. Median operative time was 87 minutes (35-125) with an intraoperative bleeding of 50 (0-300) mL. No patient presented intraoperative complications or reconversion. Median length of stay was 1 (1-6) days. Only one patient presented postoperative complications. CONCLUSION: The PRA is feasible, reproducible and safe, even during the initial learning curve, presenting a clear early recovery with a shorter surgical time.


OBJETIVO: La suprarrenalectomía laparoscópica transperitoneal (SLT) se considera el tratamiento de elección de los tumores suprarrenales benignos y de pequeño tamaño. En los últimos años el acceso retroperitoneoscópico en decúbito prono (SRP) ha ganado popularidad por las ventajas que ofrece con respecto a la SLT, al emplear un menor tiempo quirúrgico y obtener una recuperación más rápida sin aumentar las complicaciones, a expensas de una curva de aprendizaje dificultada por emplear un campo quirúrgico diferente al habitual.MATERIAL Y MÉTODOS: Nuestro objetivo es describir la técnica quirúrgica de SRP y nuestra experiencia inicial evaluando su factibilidad, seguridad y efectividad en una serie prospectiva de pacientes. Se analizaron un total de 11 SRP (9 izquierdas y 2 derechas) realizadas entre marzo de 2017 y febrero de 2020. RESULTADOS: La mediana de edad fue de 55 (36-65) años con un IMC de 25,69 Kg/m2 (20,8-34,5). El 54,55% tenía un ASA≥3. El 63,37% de los tumores suprarrenales fueron hormonalmente funcionantes. El tamaño medio fue de 4 cm (0,6-8), siendo el adenoma cortical la anatomía patológica predominante (72,72%). No se realizó ningún feocromocitoma. La mediana de tiempo quirúrgico fue de 87 minutos (35-125) con un sangrado intraoperatorio de 50mL (0-300). Ningún paciente presentó complicaciones intraoperatorias o reconversión. La mediana de días de ingreso fue de1 (1-6) día. Sólo un paciente presentó complicaciones postoperatorias. CONCLUSIONES: La SRP es factible, reproducible y segura, incluso durante la curva de aprendizaje inicial, presentando una clara recuperación temprana con un tiempo quirúrgico corto.

ABSTRACT

Introducción: La cirugía en directo se ha convertido en una excelente herramienta para la formación médica. Pese a ello, existe controversia sobre la seguridad de los pacientes que participan.ObjetivoAnalizar los resultados de las cirugías en directo realizadas en 17 cursos consecutivos de retroperitoneoscopia organizados en nuestro centro, en los cuales se intervinieron nefrectomías parciales (NP), nefrectomías radicales (NR) y nefroureterectomías (NU).Material y métodosRevisión realizada desde enero del 2010 a octubre del 2017 de todas las cirugías en directo ejecutadas por un equipo quirúrgico experto en los cursos de retroperitoneoscopia, comparadas con un grupo control de cirugías llevadas a cabo de forma ordinaria y que fue emparejado en relación con la edad, el índice de masa corporal y las comorbilidades (1:1 por cada NR y 1:2 por cada NP y NU).ResultadosSe analizaron 21 cirugías en directo (ocho NP, siete NR y seis NU) con una mediana de seguimiento global de 38 meses. No se observaron diferencias significativas entre las cirugías de los cursos y los controles en cuanto a las variables perioperatorias (tiempo quirúrgico, sangrado operatorio y complicaciones intraoperatorias) ni en las complicaciones postoperatorias y los días de ingreso. Tampoco encontramos diferencias en la tasa de recidiva en los tres grupos (NP: 0% vs. 6,3%, p = 0,47, NU: 33,3% vs. 66,7%, p = 0,180, NR: 0% vs. 28,6%, p = 0,127).ConclusiónLa cirugía en directo realizada, por cirujanos expertos, en un ambiente adecuado y con pacientes idóneos no representa un riesgo añadido de complicaciones para estos y permite mantener los mismos resultados oncológicos.

Introduction: Live surgery has become an excellent tool for medical training. Despite this, there is controversy about the safety of the patients involved.ObjectiveTo analyze the results of live surgeries performed in 17 consecutive retroperitoneoscopy courses organized in our center. Procedures performed were partial nephrectomy (PN), radical nephrectomy (RN) and nephroureterectomy (NU).Material and methodsReview from January 2010 to October 2017 of all live surgeries carried out by an expert surgical team in the retroperitoneoscopy courses, compared with a control group of surgeries performed in standard conditions. A matching (1:1 for each RN and 1:2 for each PN and NU) according to age, body mass index and comorbidities was performed.ResultsTwenty-one live surgeries were analyzed (eight PN, seven RN and six NU) with a global median follow-up of 38 months. No significant differences were observed between both groups in terms of perioperative variables (operative time, operative bleeding and intraoperative complications) or of postoperative complications and length of hospital stay. Likewise, there were no differences between recurrence rates (PN: 0% vs. 6.3%, p = 0.47, NU: 33.3% vs. 66.7%, p = 0.180, RN: 0% vs. 28.6%, p = 0,127).ConclusionsLive surgery in the hands of expert surgeons in a suitable environment and with well-selected patients does not increase the risk of complications and allows maintaining the same oncological outcomes.

ABSTRACT

Introducción: El abordaje retroperitoneoscópico posterior es una técnica poco extendida en España para la suprarrenalectomía a pesar de que, según algunos autores, ofrece ventajas respecto al acceso laparoscópico anterior o lateral. El objetivo del estudio fue identificar aquellas características que permitieran seleccionar los casos más favorables para iniciarse en esta técnica. Métodos: Estudio observacional de una cohorte de 50 pacientes intervenidos mediante suprarrenalectomía retroperitoneoscópica posterior (SRP) en un único centro. Se evaluó: sexo, edad e índice de masa corporal (IMC), tiempo operatorio, lateralidad, tamaño y características anatomopatológicas de las lesiones, tasa de conversión, complicaciones y estancia hospitalaria. Resultados: Se intervinieron 25 (50%) mujeres y 25 (50%) hombres con un tiempo operatorio mediano de 80 minutos (45-180). Se observó un tiempo operatorio significativamente menor en mujeres (p = 0,002) y en adenomas (p = 0,002). En cambio, no se observó correlación entre el tiempo quirúrgico e IMC, lateralidad o tamaño de la lesión. No hubo ningún caso de conversión. Las complicaciones fueron del 14% y la mayoría fueron leves, según la Escala de Clavien Dindo (i). La estancia hospitalaria mediana fue de dos días. Conclusiones: La suprarrenalectomía retroperitoneoscópica por vía posterior es una técnica segura, reproducible y con muy buenos resultados. Los casos más favorables para iniciar la implantación de este abordaje son mujeres con adenomas suprarrenales. (AU)


Introduction: The posterior retroperitoneoscopic approach (PRA) is seldom used in our country to perform adrenalectomies, although it offers possible advantages over laparoscopic anterior or lateral access, according to some authors. The aim of this study was to identify those features that determine the most suitable cases to start the implementation of this technique. Methods: A prospective observational study was performed with a 50 patients cohort. All the cases were operated using the PRA. Sex, age, body mass index (BMI), operative time, left or right side, size and anatomopathological characteristics of the lesion, conversion rates, complications and hospital stay were analyzed. Results: 25 (50%) women and 25 (50%) men underwent surgery, with a median operative time of 80 minutes (45-180). A significantly shorter operative time (p = 0.002) was observed in women and in adenomas (p = 0.002). However, no correlation was observed between surgical time and BMI, lesion side or lesion size. There were no conversions. The complication rate was 14%, and most of the complications were grade i in Clavien Dindo's Scale. Median hospital stay was two days. Conclusions: Retroperitoneoscopic adrenalectomy by posterior approach is a safe and reproducible procedure, with very good outcomes. The most suitable cases to implement this technique would be female patients with adrenal adenomas. (AU)

ABSTRACT

INTRODUCTION: Laparoscopic partial nephrectomy is the recommended treatment for tumours smaller than 4cm in cases where it is feasible. Depending on the location of the tumour, the transabdominal or direct retroperitoneal pathway may be considered. OBJECTIVE: To compare the transperitoneal (TPPN) and direct retroperitoneal (RPPN) partial nephrectomies performed between 2007 and 2016. MATERIAL AND METHODS: A retrospective study was conducted on 71 patients who underwent TPPN (42) or direct RPPN (29) partial nephrectomy. We evaluated the characteristics of the patients and tumours, including tumour complexity (PADUA, RENAL, C-index). We compared perioperational variables, including the complications between the 2 pathways. RESULTS: We found no differences in terms of age, sex, Charlson's score and BMI. A larger proportion of patients in the direct RPPN group had prior major abdominal surgery (7.1 vs. 24.1%; P=.043). There were no differences in tumour size, laterality, polarity or complexity in any of the assessed scores. There were significant differences in tumour location (anterior/middle/posterior) between the TPPN and RPPN groups (54.8/31/14.3 vs. 3.4/13.8/82.8%; P<.001). There were no differences in the surgical time or length of stay. The TPPN group had a smaller urinary tract opening (4.8 vs. 27.6%; P=.007) and a higher percentage of haemostatic renorrhaphy (47.6 vs. 17.2%; P=.008). There were no differences in the need for warm ischaemia, in the changes in haemoglobin levels or in the glomerular filtration rate. The complication rates were similar for the two series. CONCLUSION: The two pathways show similar results in terms of renal function preservation, complications and oncological results. However, we recommend understanding both techniques and adapting the access type to the clinical case.

ABSTRACT

BACKGROUND: The guidelines recommend partial surgery for T1 renal tumours. Various aspects of this surgery have evolved in recent years, including the clamping method and duration, enucleation, the retroperitoneoscopic approach and the use of 3mm ports. We present our initial series on laparoscopic renal tumourectomy by retroperitoneoscopy (LRTR) and analyse our learning curve and use of 3-mm instrumentation. MATERIAL AND METHODS: From January 2011 to January 2015, we performed LRTR on 50 patients with posterior or convex T1 renal tumours. After 10 cases, the technique changed to off-clamp, and 11 cases were subsequently performed with 3mm instrumentation. RESULTS: The mean tumour size was 34.36 mm (14-62), with a mean PADUA score of 8.42 (5-12). The mean operative time was 163.1 minutes (75-300), and the mean warm ischaemia time was 4.21 minutes (0-28). The main renal artery was not clamped in 41 (82%) patients, and no vessel (zero ischaemia) was clamped in 39 (78%) patients. Seven cases had positive margins (6 focal). Eleven LRTRs were performed with 3mm instrumentation, with shorter surgical times, less intraoperative bleeding and shorter hospital stays. CONCLUSIONS: Retroperitoneoscopy coupled with enucleation enables the extirpation without clamping of posterior renal tumours, with a relatively short learning curve. The 3-mm material enables the technique to be performed, although in our experience it has resulted in a higher rate of positive surgical margins.

ABSTRACT

This work aims to investigate the anatomical basis and clinical application value of renal pedicle locating in retroperitoneoscopic nephrectomy. To summarize the anatomical basis of renal pedicle locating through retrospective analysis of 278 cases of retroperitoneoscopic nephrectomy from July 2007 to September 2009, during which renal pedicle was located at about 2-4 cm below the medial arcuate ligament of the diaphragm in the space between the psoas major muscle and inferior vena cava (abdominal aorta) in the anatomical level of space before psoas. The operation of 278 patients was all successfully completed, where renal pedicle was quickly found. It took 3.5+/-1.3 min to locate the renal pedicle, and 95.6+/-23.8 min to operate. In retroperitoneoscopic nephrectomy, it is most preferable to locate renal pedicle in the space before psoas. The renal pedicle is located exactly at about 2-4 cm below the medial arcuate ligament of the diaphragm in the space between the psoas major muscle and inferior vena cava (abdominal aorta). The time for locating the renal pedicle can be shortened if the surgeon is familiar with the anatomic features of renal pedicle in retroperitoneoscopy, thereby saving the operation time.


El objetivo del estudio fue investigar las bases anatómicas y el valor de la aplicación clínica de la localización del pedículo renal en la nefrectomía retroperitoneoscópica. Para resumir las bases anatómicas de la localizacion del pedículo renal se realizó el análisis retrospectivo de 278 casos de nefrectomía retroperitoneoscópica desde Julio del 2007 a Septiembre del 2009. El pedículo renal se encontró a unos 2-4 cm por debajo del ligamento arqueado medial del diafragma en el espacio entre el músculo psoas mayor y vena cava inferior (o parte abdominal de la aorta) en el nivel anatómico del espacio anterior al músculo psoas mayor. La cirugía de los 278 pacientes fue completada exitosamente, encontrándose rápidamente el pedículo renal. El procedimiento para localizar el pedículo renal tomó 3,5+/-1,3 minutos y la cirugía completa 95.6+/-23.8 minutos. En la nefrectomía retroperitoneoscópica, es preferible localizar el pedículo renal en el espacio anterior al músculo psoas mayor. El pedículo renal se encuentra alrededor de 2-4 cm por debajo del ligamento arqueado medial de la membrana en el espacio entre el músculo psoas mayor y vena cava inferior (parte abdominal de la aorta). El tiempo para localizar el pedículo renal se puede disminuir si el cirujano está familiarizado con las características anatómicas del pedículo renal en la retroperitoneoscopía, ahorrando así el tiempo total de la cirugía.

ABSTRACT

Introducción: inicialmente los urólogos accedieron al tracto urinario superior mediante el abordaje transperitoneal para luego, desarrollar el abordaje lumboscópico o la retroperitoneoscopia, mediante la cual se accede directamente al retroperitoneo y se evitan las lesiones de los órganos intrabdominales y la contaminación de la cavidad abdominal con la orina. Objetivo: caracterizar los resultados obtenidos con el empleo de la cirugía lumboscópica como tratamiento quirúrgico. Métodos: se realizó una investigación retrospectiva, descriptiva y longitudinal en el Centro Nacional de Cirugía de Mínimo Acceso, en 327 pacientes a los que se les realizó cirugía mediante abordaje lumboscópico. Resultados: las intervenciones quirúrgicas que más se realizaron fueron la ureterolitotomía (55,9 por ciento) y la nefrectomía simple (17,7 por ciento). El tiempo quirúrgico medio fue de 120 min. La conversión fue necesaria en el 2,5 por ciento de los pacientes. Las complicaciones transoperatorias se produjeron en el 10,7 por ciento de los pacientes y de ellas fueron mayores solo el 1,2 por ciento. La hipercapnia fue una complicación transoperatoria que se presentó en un 11,9 por ciento en relación con la vía de acceso directa al retroperitoneo. Conclusiones: la ureterolitotomía fue la intervención más frecuente; los tiempos quirúrgicos dependieron de la complejidad de los procedimientos. Esta vía de abordaje fue factible por su bajo porcentaje de conversión a otro acceso quirúrgico, así como segura por su bajo índice de complicaciones mayores, lo que la hace útil para intervenciones quirúrgicas urológicas del tracto urinario superior


Introduction: at first, urologists accessed the upper urinary tract transperitoneally. Later on they developed the lumboscopic approach or retroperitoneoscopy, accessing the retroperitoneum directly, thus preventing intra-abdominal lesions and the contamination of the abdominal cavity with urine. Objective: characterize the results obtained with the use of lumboscopic surgery as surgical treatment. Methods: a retrospective longitudinal descriptive study was conducted at the National Center for Minimal Access Surgery with 327 patients, who underwent lumboscopic approach surgery. Results: the most common surgical interventions were ureterolithotomy (55.9 percent) and simple nephrectomy (17.7 percent). Mean surgical time was 120 min. Conversion was required in 2.5 percent of the patients. Transoperative complications occurred in 10.7 percent of the patients, and only 1.2 percent of them were major. Hypercapnia was a transoperative complication occurring in 11.9 percent in relation to the direct route of access to the retroperitoneum. Conclusions: ureterolithotomy was the most common intervention. Surgical times were in accordance with the complexity of procedures. Feasibility of this route of access was due to its low percentage of conversion to a different surgical access route. Its safety was due to its low rate of major complications, which makes it useful for urological surgical interventions of the upper urinary tract.

ABSTRACT

Introducción: inicialmente los urólogos accedieron al tracto urinario superior mediante el abordaje transperitoneal para luego, desarrollar el abordaje lumboscópico o la retroperitoneoscopia, mediante la cual se accede directamente al retroperitoneo y se evitan las lesiones de los órganos intrabdominales y la contaminación de la cavidad abdominal con la orina. Objetivo: caracterizar los resultados obtenidos con el empleo de la cirugía lumboscópica como tratamiento quirúrgico. Métodos: se realizó una investigación retrospectiva, descriptiva y longitudinal en el Centro Nacional de Cirugía de Mínimo Acceso, en 327 pacientes a los que se les realizó cirugía mediante abordaje lumboscópico. Resultados: las intervenciones quirúrgicas que más se realizaron fueron la ureterolitotomía (55,9 por ciento) y la nefrectomía simple (17,7 por ciento). El tiempo quirúrgico medio fue de 120 min. La conversión fue necesaria en el 2,5 por ciento de los pacientes. Las complicaciones transoperatorias se produjeron en el 10,7 por ciento de los pacientes y de ellas fueron mayores solo el 1,2 por ciento. La hipercapnia fue una complicación transoperatoria que se presentó en un 11,9 por ciento en relación con la vía de acceso directa al retroperitoneo. Conclusiones: la ureterolitotomía fue la intervención más frecuente; los tiempos quirúrgicos dependieron de la complejidad de los procedimientos. Esta vía de abordaje fue factible por su bajo porcentaje de conversión a otro acceso quirúrgico, así como segura por su bajo índice de complicaciones mayores, lo que la hace útil para intervenciones quirúrgicas urológicas del tracto urinario superior(AU)


Introduction: at first, urologists accessed the upper urinary tract transperitoneally. Later on they developed the lumboscopic approach or retroperitoneoscopy, accessing the retroperitoneum directly, thus preventing intra-abdominal lesions and the contamination of the abdominal cavity with urine. Objective: characterize the results obtained with the use of lumboscopic surgery as surgical treatment. Methods: a retrospective longitudinal descriptive study was conducted at the National Center for Minimal Access Surgery with 327 patients, who underwent lumboscopic approach surgery. Results: the most common surgical interventions were ureterolithotomy (55.9 percent) and simple nephrectomy (17.7 percent). Mean surgical time was 120 min. Conversion was required in 2.5 percent of the patients. Transoperative complications occurred in 10.7 percent of the patients, and only 1.2 percent of them were major. Hypercapnia was a transoperative complication occurring in 11.9 percent in relation to the direct route of access to the retroperitoneum. Conclusions: ureterolithotomy was the most common intervention. Surgical times were in accordance with the complexity of procedures. Feasibility of this route of access was due to its low percentage of conversion to a different surgical access route. Its safety was due to its low rate of major complications, which makes it useful for urological surgical interventions of the upper urinary tract.(AU)

ABSTRACT

Introducción: La cirugía urológica laparoscópica ha avanzado de manera considerable en los últimos años, introduciéndose el abordaje retroperitoneal como una opción ventajosa. Objetivos: Presentar la experiencia en la conducción anestésica perioperatoria de los procedimientos lumboscópicos. Método: Investigación retrospectiva, descriptiva y longitudinal. Se incluyeron todas las historias clínicas de los pacientes programados para cirugía lumboscopica urológica en el Centro Nacional de Cirugía de Mínimo Acceso (CNCMA) desde agosto de 1999 a diciembre del 2010. De las Historias clínicas, se extrajeron las variables: edad, sexo, peso, tiempo quirúrgico, enfermedades asociadas, capnometría y complicaciones con significación clínica durante el acto anestésico quirúrgico y postoperatorio. Para todas las variables cuantitativas se determinaron estadígrafos descriptivos (media, mínimo, máximo, desviación estándar, coeficiente de variación). Para todas las variables cualitativas se realizaron tablas de frecuencias. El análisis estadístico se realizó a través del paquete SPSS versión 11.05. Los resultados fueron expresados a través de tablas y gráficos. Resultados. Se realizaron 324 casos, 211 hombres y 113 mujeres. El proceder quirúrgico fue: nefrectomías 58, pieloplastia 1, pielolitotomías 5, ureterolitotomías 183 y quistes renales 77. De ellos 30 pacientes presentaron enfisema subcutáneo lumbar y 82 % de los mostraron valores de CO2 al final de la espiración superior a 50 mmHg, al menos en una medición intraoperatoria. No se constató evidencia clínica de embolismo gaseoso. Conclusiones: El éxito de los procedimientos lumboscópicos depende de una correcta selección de los pacientes y del trabajo en equipo anestesiólogo cirujano.


The laparoscopic urological surgery has advanced considerably in recent years, introducing the retroperitoneal approach as an advantageous option. Objectives: To present the experience of driving anesthetic perioperative retroperitoneal procedures. Method: Research retrospective, descriptive and longitudinal. We included all medical records of patients scheduled for urological retroperitoneal surgery at the National Centre for Minimal Access Surgery (CNCMA) from August 1999 to December 2010.

ABSTRACT

Apesar da laparoscopia ser amplamente utilizada na abordagem de doenças retroperitoneais, ainda são poucos os relatos de ressecção laparoscópica de tumores retroperitoneais. Este estudo descreve um caso de Schwannoma retroperitoneal benigno tratado por retroperitoneoscopia e discute a dificuldade no diagnóstico e as vantagens do acesso retroperioneal por via laparoscópica.


In spite laparoscopy has been widely utilized in the management of retroperitoneals pathologies, there are still few reports of laparoscopic resections of retroperitoneals tumors. We report a case of a retroperitoneal benign Schwannoma treated by retroperitoneoscopy. The troubles on diagnostic and advantages of the retroperitoneal approach by laparoscopic way are discussed.

ABSTRACT

Objetivo: El espacio retroperitoneal es limitado, hecho que se hace más evidente en laparoscopia pediátrica. El objetivo es presentar nuestra experiencia con la posición retroperitoneoscópica en prono utilizando un instrumento de trabajo, analizando las ventajas y detalles técnicos que favorecerían su aplicación. Metodos: Seguimiento prospectivo de pacientes operados por el autor principal con técnica retroperitoneoscopia en posición prono. Con el paciente en posición prono, se crea el espacio retroperitoneal con técnica cerrada y balón realizado con dedo guante. Bajo visón directa, un segundo trocar es insertado en la punta de la 11ª costilla. La fascia de Gerota es disecada hasta identificar el hilio renal. Luego de dividir los vasos ayudado por la fuerza de gravedad, se realiza la nefrectomía. La pieza es removida íntegramente o con bolsa ad-hoc. Se analizó datos epidemiológicos, diagnóstico, seguimiento, complicaciones y comparación entre centros. Resultados: Entre el 1 de septiembre de 2005 y el 31 de agosto de 2006, se operaron 8 pacientes con la técnica descrita; 5 niñas y 3 niños. Su edad y peso promedio fueron 3 años (rango 1-4a) y 19 kilos (rango 9-30k) respectivamente. Los diagnósticos fueron riñón multicístico (n=4) atrofia renal por RVU (n=3) y doble sistema renal (n=1). Se realizaron 5 nefrectomías y 3 nefroureterectomías con un tiempo promedio de cirugía de 103 min. (rango 60-180). Todos los pacientes fueron completados laparoscópicamente con 1 instrumento de trabajo. El tiempo de hospitalización promedio del grupo fue de 24 hrs (rango 20-36). No hubo complicaciones perioperatorias. El tiempo de seguimiento promedio es de 11 meses (rango 7-15) sin complicaciones hasta la fecha. Conclusión: Esta serie muestra que la retroperitoneoscopia en posición prono ofrece un espacio de trabajo adecuado. Esto podría explicarse por el uso de la fuerza de gravedad como tracción...


Objective: The retroperitoneal space is limited for endoscopic surgery; this is a more obvious fact in paediatric laparoscopy. The aim of this study is to show our experience with the posterior prone retroperitoneoscopy (RP) using a single working instrument, analyzing advantages and technical issues, which may improve its application. Methods: Prospective study of all patients operated by the main author using a posterior prone RP technique in two institutions. With the patient in prone position, a retroperitoneal working space is created using close technique and the aid of a homemade balloon. Under direct vision, the working port is placed at the tip of the 11th rib. Gerota´s fascia is incised and hilar vessels identified. The vessels are divided using gravity as traction. The specimen is removed via camera port or using endobag. Demographic, follow-up and complications data were compared between both centres. Results: In a year period (1st September 2005- 31st August 2006), 8 patients underwent the described technique; 5 girls and 3 boys. Mean age and weight were 3 years (1-4) y 19 kilos (9-30), respectively. Clinical diagnoses were Multicystic Dysplastic Kidney (n=4) dysplastic kidney with VUR (n=3) y and Duplex Kidney (n=1). 5 nephrectomies and 3 nephroureterectomies were performed with a mean surgical time of 103 min (60-180). All procedures were completed with a single working instrument. Mean hospital stay was 24 hrs. (20-36). There were no perioperative complications. Mean follow-up time was 11 month (7-15). Conclusions: This series showed that posterior prone PR offers an adequate working endoscopic space. This might be explained by the use of gravity as a traction, which allows surgical team to work with a single instrument.The authors recommend this technique for RP in children, especially for nephrectomies.
