Digital imaging, virtual and augmented reality.

The sensorial perception of what is captured is what we know as "image" and consists of a static component and a dynamic process. This continuous process of images capture is essential in surgery. The image is crucial for the surgeon, who requires it for the diagnosis, for the therapeutic process and for postoperative follow-up. In minimally invasive surgery the sequence of images is essential and promotes the appearance of digital video. Digital video is the representation of moving images in the form of encoded digital data, unlike classic analog video, with continuous analog signals. Beyond what we can consider the "real image" (what we see as part of the existing reality) other realities appear in these decades; the Virtual Reality and Augmented Reality. With these realities we refer in the medical ambitus to the creation or superposition, respectively, of a three-dimensional virtual environment to support healthcare and teaching or research processes. Today, these technologies have already begun to be integrated into various surgical specialties, with predictive surgical planning and intraoperative navigation us their main applications. When using these digital environments, it is difficult to completely separate virtual reality from augmented reality, often being Mixed Reality. The current developments offer an environment that mixes the best aspects of both, unifying the simulation and requiring a single helmet or glasses to enjoy the sensorial experience. In this fusion of realities it will be possible to simultaneously create a virtual world from scratch to which we can add virtual elements from our real environment.

Ensayo clínico multicéntrico para la resección de pólipos rectales mediante un nuevo dispositivo de acceso transanal híbrido laparoendoscópico / Multicenter clinical trial for the resection of rectal polyps using a new laparoendoscopic hybrid transanal access device

Introducción: Los pólipos complejos requieren el uso de técnicas endoscópicas avanzadas o la cirugía mínimamente invasiva para su abordaje. En los pólipos rectales es de especial relevancia llegar a un consenso de cuál es el mejor abordaje de estos para evitar infratratamientos o sobretratamientos que incrementen una morbimortalidad innecesaria. Métodos: Se describe un ensayo clínico piloto con un producto sanitario de primer uso en humanos multicéntrico y prospectivo. Se plantea la hipótesis que UNI-VEC® facilita la cirugía laparoendoscópica transanal para la extirpación de tumores rectales precoces. El objetivo principal es evaluar que es seguro y cumple los requisitos funcionales establecidos. Los secundarios son evaluar resultados, complicaciones y nivel de satisfacción.Resultados: Se reclutaron 16 pacientes en 12 meses con un seguimiento mínimo de dos meses. El tamaño medio ha sido de 3,4 cm, siendo el pólipo mayor de 6 cm. Respecto a la localización, la media se encontraba a 6,6 cm del margen anal. Se realizó resección endoscópica mucosa (REM) (6,3%), disección submucosa endoscópica (DSE) (43,8%), resección espesor completo (REC) (6,3%) y transanal minimally invasive surgery (TAMIS) (43,8%). El tiempo medio fueron 73,25 min; 56,3% utiliza una cámara de 30̊ y 43,8% el endoscopio flexible como instrumento de visión. El 56,3% son lesiones benignas y 43,8% malignas. En 87,5% se consigue resección completa. En cuanto a las complicaciones, se presenta sangrado leve (Clavien I) en 25, 6,3 y 21,4% a las 24 h, 48 h y siete días, respectivamente. La continencia se valora según la Escala de Wexner. A los siete días, 60% presentan continencia perfecta, 26,7% IF leve y 13,3% IF moderada. A los 30 días, 66,7% continencia perfecta, 20% IF leve y 13,3% IF moderada. A los dos meses se revisan cuatro de los pacientes que a los 30 días presentaban un Wexner superior al preoperatorio y se demuestra continencia perfecta en 25% de los pacientes, 50% leve y 25% moderada.

Introduction: Complex polyps require the use of advanced endoscopic techniques or minimally invasive surgery for their approach. In rectal polyps it is of special relevance to reach a consensus on the best approach to avoid under- or overtreatment that increases unnecessary morbidity and mortality. Methods: We describe a prospective, multicenter, pilot clinical trial with a first-in-human medical device. It is hypothesized that UNI-VEC® facilitates transanal laparoendoscopic surgery for the removal of early rectal tumors. The primary objective is to evaluate that it is safe and meets the established functional requirements. Secondary objectives are to evaluate results, complications and level of satisfaction. Results: Sixteen patients were recruited in 12 months with a minimum follow-up of 2 months. The mean size was 3.4 cm with the largest polyp being 6 cm. Regarding location, the mean was 6.6 cm from the anal margin. Endoscopic mucosal resection (EMR) (6.3%), endoscopic submucosal dissection (ESD) (43.8%), REC (6.3%) and TAMIS (43.8%) were performed. The mean time was 73.25 min. The 56.3% used a 30° camera and 43.8% used the flexible endoscope as a viewing instrument. The 56.3% were benign lesions and 43.8% malignant. Complete resection is achieved in 87.5%. Regarding complications, mild bleeding (Clavien I) occurred in 25%, 6.3% and 21.4% at 24 h, 48 h and 7 days, respectively. Continence was assessed according to the Wexner scale. At 7 days, 60% showed perfect continence, 26.7% mild FI and 13.3% moderate FI. At 30 days, 66.7% had perfect continence, 20% mild FI and 13.3% moderate FI. At 2 months, 4 patients were reviewed who at 30 days had a Wexner's degree higher than preoperative and perfect continence was demonstrated in 25% of the patients, 50% mild and 25% moderate. (AU)

The economic impact of anastomotic leak after colorectal cancer surgery.

OBJECTIVE: To determine the economic impact of the incremental consumption of resources for the diagnosis and treatment of anastomotic leak (AL) in patients after resection with anastomosis for colorectal cancer compared to patients without AL on the Spanish health system. METHOD: This study included a literature review with parameters validated by experts and the development of a cost analysis model to estimate the incremental resource consumption of patients with AL versus those without. The patients were divided into three groups: 1) colon cancer (CC) with resection, anastomosis and AL; 2) rectal cancer (RC) with resection, anastomosis without protective stoma and AL; and 3) RC with resection, anastomosis with protective stoma and AL. RESULTS: The average total incremental cost per patient was €38,819 and €32,599 for CC and RC, respectively. The cost of AL diagnosis per patient was €1018 (CC) and €1030 (RC). The cost of AL treatment per patient in Group 1 ranged from €13,753 (type B) to €44,985 (type C + stoma), that in Group 2 ranged from €7348 (type A) to €44,398 (type C + stoma), and that in Group 3 ranged from €6197 (type A) to €34,414 (type C). Hospital stays represented the highest cost for all groups. In RC, protective stoma was found to minimize the economic consequences of AL. CONCLUSIONS: The appearance of AL generates a considerable increase in the consumption of health resources, mainly due to an increase in hospital stays. The more complex the AL, the higher the cost associated with its treatment. INTEREST OF THE STUDY: it is the first cost-analysis study of AL after CR surgery based on prospective, observational and multicenter studies, with a clear, accepted and uniform definition of AL and estimated over a period of 30 days.

At 2 months, 4 patients were reviewed who at 30 days had a Wexner's degree higher than preoperative and perfect continence was demonstrated in 25% of the patients, 50% mild and 25% moderate. In no case did rectal perforation or major complications requiring urgent reintervention occur. As for the level of reproducibility, safety, level of satisfaction with the device and evaluation of the blister, the evaluation on a scale of 0-10 (9.43, 9.71, 9.29 and 9.50 respectively). All the investigators have previous experience with transanal devices. CONCLUSIONS: The study demonstrates the efficacy and safety of UNI-VEC® for the treatment of rectal lesions. It will facilitate the implementation of hybrid procedures that seek to solve the limitations of pure endoscopic techniques by allowing the concomitant use of conventional laparoscopic and robotic instrumentation with the flexible endoscope.

Sutura laparoscópica mecanizada con FlexDex Surgical System® para ubicaciones anatómicamente difíciles / Robotic-like suturing with FlexDex Surgical System® for difficult laparoscopic suture

El campo de la cirugía laparoscópica ha experimentado un crecimiento exponencial en los últimos años. A pesar de los grandes avances en este campo, las herramientas laparoscópicas estándar no han logrado su desarrollo óptimo, presentando ciertas deficiencias en lo que a movilidad y ergonomía se refiere. La cirugía robótica ha intentado aportar soluciones a estos problemas, sin embargo, existen inconvenientes, entre los que se encuentran su elevado coste, escasa disponibilidad y la necesidad de capacitación específica, lo que condiciona su rentabilidad y generalización de uso. Presentamos los resultados de una serie clínica prospectiva de 20 casos, en los que se ha testado la seguridad, eficacia y ergonomía de FlexDex® para la realización de suturas intracorpóreas laparoscópicas. El resultado muestra una herramienta segura y funcional que ofrece control y precisión en su manejo, además de mejorar la ergonomía del cirujano. Este dispositivo supone una alternativa que combina la precisión y el rango de movimientos de la cirugía robótica, con la mayor disponibilidad de la laparoscopia convencional. (AU)

The field of laparoscopic surgery has experienced an exponential growth in recent years. Despite great progress in this field, standard laparoscopic tools have not been optimally developed and still has some deficiencies when it comes to mobility and ergonomics. Robotic surgery has attempted to solve these problems by improving the articulation of surgical instruments. However, it presents a series of disadvantages, among which are its high cost, low availability and the need of a specific training, which conditions its profitability and hinders a widespread use. We present the results of a prospective clinical series of 20 cases in which the safety, efficacy and ergonomics of FlexDex® have been tested for performing laparoscopic intracorporeal sutures. The result is a safe and functional tool that offers both control and precision in its handling, while improves the ergonomics of the surgeon. This device represents an alternative that combines the precision and range of movements of robotic surgery with the greater availability of conventional laparoscopy. (AU)

Transoral endoluminal approach to Zenker's diverticulum using Ligasure™. Early clinical experience.

The development of minimally invasive procedures has rekindled interest in endoluminal techniques for the management of Zenker's diverticulum. Tissue sealers as employed in laparoscopic surgery have not been previously used for Zenker's diverticulum septotomy.Supported by the established safety of linear cutters, bipolar forceps, and ultrasonic scalpels, we have started a procedure using the Ligasure 5™ tissue sealer. Safety and efficacy results in our early clinical experience are shown for a prospective series of 5 consecutive Zenker's diverticulum cases that were perorally managed with tissue sealing.The procedure was quickly and safely performed in the endoscopy room under sedation. Mean number of seals per patient was 2, and mean procedure duration was 33 minutes. No complications developed during or after the procedure, and patients were discharged with immediate dysphagia relief and adequate oral tolerance. No diverticular relapses occurred after a mean follow-up of 21 months (range 18-30). This procedure may be repeated as often as desired with no need for hospital admission. Safety should be prospectively assessed by further studies using a higher number of procedures.

Tratamiento endoluminal transoral del divertículo de Zenker con LigasureTM. Experiencia clínica inicial / Transoral endoluminal approach to Zenker's diverticulum using LigasureTM. Early clinical experience

El desarrollo de los procedimientos mínimamente invasivos ha reavivado el interés por las técnicas endoluminales para el tratamiento del divertículo de Zenker. Los selladores titulares empleados en cirugía laparoscópica no han sido empleados previamente en la septotomía del divertículo de Zenker. Avalados por la seguridad previa del empleo de las cortadoras lineales, de las pinzas bipolares y de los bisturís por ultrasonidos, hemos iniciado dicho procedimiento mediante el empleo del sellador tisular Ligasure 5TM. Se muestran los resultados de seguridad y eficacia en la experiencia clínica inicial de una serie prospectiva de 5 casos consecutivos de divertículo de Zenker tratados por vía peroral con el sellador tisular. El procedimiento se realizó en la sala de endoscopia, con sedación, de manera rápida y segura. La media de sellados por paciente fue de 2 y la duración media del procedimiento de 33 minutos. No se presentaron complicaciones durante el procedimiento ni derivadas del mismo, siendo dados de alta los pacientes con desaparición inmediata de la disfagia y correcta tolerancia oral. Con un seguimiento medio de 21 meses (rango 18-30), no existió recidiva del divertículo en ningún caso. Este procedimiento puede ser repetido tantas veces como se desee y ser realizado sin ingreso hospitalario. La seguridad mostrada deberá ser evaluada prospectivamente en estudios posteriores con mayor número de procedimientos (AU)

Duodenopancreatectomía en ancianos. Evaluación de resultados / Duodenopancreatectomy in the elderly. Evaluation of results

Introducción Con el aumento de la esperanza de vida, cada vez se diagnostican más tumores periampulares resecables en la población geriátrica. A pesar de la disminución de la mortalidad postoperatoria, el debate sobre la relación riesgo-beneficio de la duodenopancreatectomía cefálica (DPC) en ancianos sigue vigente.Objetivo Analizar la morbimortalidad de la DPC en los pacientes mayores de 70 años. Diseño Estudio prospectivo observacional. Pacientes Entre enero de 2005 y diciembre 2010, se realizaron 54 duodenopancreatectomías. Se compararon 2 grupos de pacientes: grupo 1 (pacientes>70 años, n: 24), y grupo 2 (pacientes<70 años, n: 30). Se analizó la morbimortalidad, transfusión, reintervenciones, estancia media y supervivencia. Resultados El grupo>70 años incluyó más pacientes ASA 2 y 3 (p=0,010), y presentaron mayor número de antecedentes personales por paciente (p=0,037). La mortalidad postoperatoria fue superior en el grupo de más edad, aunque sin diferencias significativas (8,3 vs. 3,3%). La morbilidad postoperatoria (45,8 vs. 46,6%), la tasa de reintervenciones (16,6 vs. 13,3%), la estancia hospitalaria (18 vs. 13 días), y la supervivencia a 6 y 12 meses, tampoco presentaron diferencias significativas (84 y 72% vs. 90 y 86%).Conclusiones La edad no parece ser una contraindicación por sí misma para la DPC, si bien los ancianos presentan mayor riesgo de complicaciones debido a los cambios fisiológicos relacionados con el envejecimiento. La disparidad de resultados evidencia la necesidad de disponer de estudios poblacionales de ámbito nacional que aporten una visión global de la morbimortalidad en la DPC (AU)

Introduction With the increase in life expectancy, more and more resectable periampullary tumours are being diagnosed in the geriatric population. Despite the decrease in post-operative mortality, there continues to be a debate on the risk-benefit of cephalic duodenopancreatectomy (CPD) in the elderly. Objective To analyse the morbidity and mortality of CPD in patients over 70 years-old. Design Prospective observational study. Patients A total of 54 duodenopancreatectomies were performed between January 2005 and December 2010. Two groups of patients were compared: Group 1 (patients>70 years-old, n: 24), and Group 2 (patients<70 years-old, n: 30). The morbidity and mortality, transfusion, reinterventions, mean hospital stay, and survival were analysed. Results The>70 years group included more ASA 2 and 3 patients (P=.010), and had a higher number of previous medical problems per patient (P=.037). The post-operative mortality was higher in the older age group, although the difference was not significant (8.3 vs 3.3%). There were also no significant differences in post-operative morbidity (45.8 v. 46.6%), reintervention rate (16.6 vs 13.3%), length of hospital stay (18 vs 13%), and survival at 6 and 12 months (84 and 72% vs 90 and 86%).Conclusions Age, in itself, does not seem to be a contraindication for CPD, but the elderly do have a higher risk of complications due to the physiological changes associated with ageing. The disparity of results demonstrates the need for more population studies at national level that may give an overall view of morbidity and mortality in CPD (AU)

Estandarizando la sigmoidectomía por incisión umbilical única / Standardising sigmoidectomy by single umbilical incision

El auge de la cirugía endoscópica de única incisión hace que cada vez sean más los procedimientos y los grupos quirúrgicos que se suman a su realización La resección cólica es el procedimiento que más se va a beneficiar con la aplicación de este abordaje pues va a conseguir una minimización importante en el acceso parietal; con la minilaparotomía umbilical se agrupan las puertas de entrada y se puede realizar la extracción de la pieza y la preparación de la anastomosis. De entre los procedimiento colorrectales, la sigmoidectomía parece ser el más apropiado para el inicio en estas técnicas por los grupos con experiencia laparoscópica colorrectal. Nuestro objetivo es estandarizar la sigmoidectomía por única incisión analizando el proceso con apoyo de secuencias de vídeo y poniendo énfasis en los factores diferenciadores de la laparoscopia convencional y en los puntos clave para no tener problemas durante la ejecución del proceso (AU)

The increase in single-incision endoscopic surgery has led to more and more procedures and surgical groups who perform them. Segmental resection is the procedure most likely to benefit from this approach since it achieves a significant minimisation in the parietal access; with umbilical mini-laparotomy the entrance ports are grouped together and extraction of the piece and preparation of the anastomosis can be performed. Among the colorectal procedures, sigmoidectomy seems to be the most appropriate area to start using these techniques by groups with laparoscopic colorectal experience. Our aim is the standardisation of single-incision sigmoidectomy, analysing the process with the support of video sequences, and placing emphasis on the factors where it differs from conventional laparoscopy and on the key points in order to avoid problems during the execution of the process (AU)

[Endoscopic transvaginal cholecystectomy]. / Colecistectomía endoscópica transvaginal.

INTRODUCTION: Transluminal endoscopic surgery through natural orifices (NOTES) allows intraperitoneal surgical procedures with minimal access to the abdominal wall. Currently it is not yet possible to perform these interventions without laparoscopic assistance, so these procedures are hybrids, fusion of minilaparoscopy and transluminal endoscopic surgery We present a prospective clinical series of patients undergoing surgery for gallstones, with hybrid NOTES transvaginal cholecystectomy with a nursing care plan adapted to this new approach. METHODS: Prospective clinical series of consecutive patients, nonrandomized, with transvaginal NOTES cholecystectomy. The surgery was performe with the assistance of two parietal entryports, one of umbilical 5 mm and 3 mm right upper quadrant of the abdomen. Analysis of nursing care plan with particular attention to safety of the procedure parameters and anxiety associated to the surgery RESULTS: There were no serious systemic complications. The main problem with this type of surgery is the fear of patients in relation to the new ways for a non-gynecological transvaginal procedures as ckolecystectomy and the risk of vaginal bleeding and urinary infection. DISCUSSION: Hybrid transvaginal cholecystectomy is a good surgical model of minimally invasive surgery. Its implementation is possible in groups with habit laparoscopic surgery, using standard instrumentation of endoscopy and laparoscopic surgery. The surgical team, doctors and nurses, must be well prepared for this new approach, because special and innovative cares are demanded.

Colecistectomía endoscópica transvaginal / Endoscopic transvaginal cholecystectomy

Introducción. La cirugía endoscópica transluminal a través de orificios naturales (NOTES) permite realizar procedimientos quirúrgicos intraperitoneales con mínimos accesos en la pared abdominal. Actualmente todavía no es posible realizar estas intervenciones sin asistencia desde puertas de entrada en la pared abdominal, por lo que los procedimientos realizados son híbridos, fusión de minilaparoscopia y cirugía endoscópica transluminal. Se presenta una serie clínica prospectiva de pacientes intervenidas por colelitiasis, a las que se practicó colecistectomía híbrida transvaginal, con un plan de cuidados de colecistectomía laparoscópica adaptado al nuevo abordaje endoscópico transvaginal. Métodos. Serie clínica prospectiva de pacientes consecutivas, no aleatorizada, intervenidas por colelitiasis mediante abordaje de fusión NOTES transvaginal y minilaparoscópico con dos puertas de entrada, umbilical de 5 mm y en hipocondrio derecho de 3 mm. Análisis del plan de cuidados de enfermería, prestando especial atención a parámetros de seguridad del procedimiento y ansiedad relacionada con la cirugía. Resultados. No existieron complicaciones generales graves. El principal problema relacionado con este tipo de cirugía es el miedo de las pacientes en relación a las nuevas vías de abordaje transvaginal para procedimientos no ginecológicos y el riesgo de sangrado vaginal y de infección urinaria. Discusión. La colecistectomía híbrida transvaginal constituye un buen modelo quirúrgico de cirugía mínimamente invasiva. Su implantación es posible en grupos quirúrgicos que tengan hábito laparoscópico, empleando instrumentación habitual de endoscopia y cirugía laparoscópica. El equipo quirúrgico -facultativos y enfermeros- debe estar bien preparado para este tipo de abordajes, pues precisan unos cuidados específicos y novedoso (AU)

NOTES. Historia y situación actual de la cirugía endoscópica por orificios naturales en nuestro país / NOTES. History and current situation of natural orifice transluminal endoscopic surgery in Spain

La cirugía endoscópica transluminal a través de orificios naturales (NOTES, del inglés Natural Orifice Translumenal Endoscopic Surgery), engloba un conjunto de nuevas vías de abordaje endoscópico de la cavidad abdominal, con ventajas potenciales sobre la cirugía laparoscópica convencional. Se fundamenta en la posibilidad de realizar técnicas quirúrgicas intraperitoneales mediante la entrada en la cavidad peritoneal a través de los orificios naturales perforando el órgano que permite la entrada directa a dicha cavidad (estómago, vagina, recto, vejiga). Posteriormente se ha postulado la posibilidad de este mismo acceso para acceder al retroperitoneo y al mediastino. A continuación se comenta como se ha desarrollado la técnica y cómo ha sido la aplicación en nuestro país, intentado dar una visión general sobre los riesgos y beneficios de la NOTES y las necesidades básicas para poder iniciarse en esta nueva cirugía (AU)

Natural orifice transluminal endoscopic surgery (NOTES), involves a group of new endoscopic approaches to the abdominal cavity, with potential advantages over conventional laparoscopic surgery. It is based on the possibility of performing intra-peritoneal surgical techniques through natural orifices by entering the peritoneal cavity through natural orifices perforating the organ that allows direct access to that cavity (stomach, vagina, rectum, bladder). The possibility of using this same route to access the retroperitoneum and mediastinum has subsequently been postulated. Comments are made on how the technique has been developed, as well as how it has been applied in our country, attempting to give a general view on the risks and benefits of NOTES and the basic requirements to be able to start in this new surgery (AU)
