Robotic surgery as a driver of surgical digitalization.

Classical surgery, also called analog surgery, is transmitted to us by our mentors, whose knowledge has been delegated from generation to generation throughout the history of surgery. Its main limitations are limited surgical precision and dependence on the surgeon's skill to achieve surgical goals. So-called digital surgery incorporates the most advanced technology, with the aim of improving the results of all phases of the surgical process. Robotic platforms are currently considered to be one of the main drivers of the digital transformation of surgery. They bring considerable advances to the digitalization of surgery, including: higher quality visualization, more controlled and stable movements with elimination of tremor, minimized risk of errors, data integration throughout the patient's surgical process, use of various systems for better surgical planning, application of virtual and augmented reality, telementoring, and artificial intelligence.

Implementación tecnológica en los servicios de Cirugía General y del Aparato Digestivo en España. Encuesta nacional y resultados / Technological implementation in General Surgery services in Spain. National survey and results

La tecnología constituye uno de los pilares de la cirugía del siglo XXI y resulta un factor clave para la consecución de unos mejores resultados quirúrgicos. El proceso quirúrgico actual lleva implícito no solo la técnica operatoria, sino un grado de especialización muy elevado y el conocimiento y empleo de técnicas y dispositivos propios de otros campos. En España no existen estudios publicados a nivel nacional a este respecto.Desde la Sección de Cirugía Mínimamente Invasiva e Innovación Tecnológica (CMI-IT) de la Asociación Española de Cirujanos hemos diseñado un estudio cuyo objetivo principal es evaluar el grado de implantación tecnológica en la especialidad de cirugía general en España, así como analizar los dispositivos disponibles en los diferentes centros del país. Nos planteamos realizar una descripción pormenorizada de las aplicaciones de dichos dispositivos y técnicas por áreas de interés, señalando las patologías y procedimientos en los que se utiliza dicha tecnología.

Technology is one of the pillars of surgery in the 21st century and is a key factor in achieving better surgical results. The current surgical process involves not only surgical techniques, but also a very high degree of specialisation and the knowledge and use of techniques and devices from other fields. In Spain, there are no studies published at a national level in this regard.From the Minimally Invasive Surgery and Technological Innovation section of the Spanish Association of Surgeons we have designed a study whose main objective is to evaluate the degree of technological implantation in the specialty of General Surgery in Spain, as well as to analyze the devices available in the different centres of the country. We propose to make a detailed description of the applications of these devices and techniques by areas of interest, pointing out the pathologies and procedures in which this technology is used. (AU)

Laparoscopic Appendectomy in the Setting of Clinical Prediction Rules.

PURPOSE: Acute appendicitis (AA) is the most frequent surgical entity in the emergency department, but its correct diagnosis remains challenging. To improve diagnosis, clinical prediction rules (CPRs) have been created to establish objective scores for the probability of suffering AA. In this study, we establish scores indicating whether laparoscopy would be superior to clinical observation or repeat diagnostic test. METHODS: A retrospective observational study was conducted with 433 patients submitted to surgery for suspected AA using a laparoscopic approach. The Alvarado, Raja Isteri Pengiran Anak Saleha Appendicitis, appendicitis inflammatory response, and adult appendicitis score scales were applied in each case to establish a high, medium, or low probability of suffering AA. RESULTS: Of the 433 patients analyzed, 381 (88.0%) had AA. Twelve (2.8%) were converted to open surgery, and complications were observed in 54 (12.5%) cases. The CPRs studied showed statistically significant differences between AA and negative appendectomies. However, in patients with intermediate probability scores, the diagnostic accuracy of the CPRs evaluated was not adequate. CONCLUSIONS: Laparoscopic surgery can serve as a diagnostic tool for patients with intermediate AA probability scores because of its low associated morbidity and mortality and because it affords a direct diagnosis of the problem, allowing determination of the appropriate treatment.

How to reduce the laparoscopic colorectal learning curve.

BACKGROUND: The laparoscopic approach for colorectal pathologies is becoming more widely used, and surgeons have had to learn how to perform this new technique. The purpose of this work is to study the indicators of the learning curve for laparoscopic colectomy in a community hospital and to find when the group begins to improve. METHODOLOGY: From January 1 2005 to December 31 2012, 313 consecutive laparoscopic colorectal surgeries were performed (105 rectal and 208 colonic) by at least 60% of the same surgical team (6 members) in each operation. We evaluate the learning curve by moving averages and cumulative sums (CUSUM) for different variables related to the surgery outcomes. RESULTS: Moving average curves for postoperative stay, fasting, and second step analgesia show a stabilizing trend toward improvement as we get more experience. However, intensive care unit stay, number of lymph nodes achieved, and operating time did not show a clear decreasing tendency. CUSUM curves of conversion, specimens<12 lymph nodes, and complications all show a clear turning point marked on all the charts around the procedure 60, accumulating a positive trend toward improvement. The CUSUM curve of the "learning variable" shows this improvement point at procedure 70. CONCLUSIONS: The laparoscopic colectomy learning curve accelerates with a collective team involvement in each procedure. The CUSUM and moving average curves are useful for initial and ongoing monitoring of new surgical procedures. The markers of the learning curve evidenced in our study are the conversion rate, postoperative surgical morbidity, and the number of patients with a lymph node count<12. WHAT IS NEW IN THIS PAPER?: The significance of this study is the evaluation of the learning curve, in laparoscopic colorectal surgery, of a surgical team in a community hospital, using moving average and CUSUM curves. This study demonstrated that the number of patients needed to achieve skilful practice decreased when there is collective team involvement in each procedure.

25 años de cirugía laparoscópica en España / 25 years of laparoscopic surgery in Spain

INTRODUCCIÓN: La introducción de la cirugía laparoscópica (CL) puede considerarse el avance más importante que ha experimentado nuestra especialidad en los últimos 25 años. A pesar de sus ventajas, la implantación y consolidación de la CL no ha sido homogénea, especialmente si tenemos en cuenta las técnicas laparoscópicas avanzadas. El objetivo de este trabajo es analizar el nivel de desarrollo e implantación de la CL en España en el momento actual y analizar su evolución en los últimos años. MATERIAL Y MÉTODOS: Durante el segundo semestre de 2012 se desarrolló una encuesta que evaluaba distintos aspectos relacionados con la implantación y el desarrollo de la CL en nuestro país. La encuesta se realizó mediante un cuestionario electrónico. RESULTADOS: La tasa global de respuesta a la encuesta fue del 16% y 103 jefes de Servicio contestaron el cuestionario. El 92% correspondió a cirujanos de centros sanitarios públicos. El 99% de los encuestados realizaba CL básica y el 85,2%, avanzada. La mayor parte de los encuestados (79%) considera que el instrumental y los equipos para CL de los que dispone son correctos y el 71% considera que, en su medio, la CL está en el lugar adecuado. CONCLUSIONES: La CL básica ha logrado desarrollarse en nuestro país hasta considerarse un estándar practicado por la mayoría de los cirujanos y ser parte de la formación básica del residente de cirugía. Con respecto a la CL avanzada, aunque los porcentajes de utilización son altos, todavía existen déficits y, en consecuencia, oportunidades de mejora

INTRODUCTION: The introduction of laparoscopic surgery (LS) can be considered the most important advancement in our specialty in the past 25 years. Despite its advantages, implementation and consolidation has not been homogenous, especially for advanced techniques. The aim of this study was to analyse the level of development and use of laparoscopic surgery in Spain at the present time and its evolution in recent years. MATERIAL AND METHODS: During the second half of 2012 a survey was developed to evaluate different aspects of the implementation and development of LS in our country. The survey was performed using an electronic questionnaire. RESULTS: The global response rate was 16% and 103 heads of Department answered the survey. A total of 92% worked in the public system. A total of 99% perform basic laparoscopic surgery and 85,2% advanced LS. Most of the responders (79%) consider that the instruments they have available for LS are adequate and 71% consider that LS is in the right stage of development in their environment. CONCLUSIONS: Basic laparoscopic surgery has developed in our country to be considered the standard performed by most surgeons, and forms part of the basic surgical training of residents. With regards to advanced LS, although it is frequently used, there are still remaining areas of deficit, and therefore, opportunities for improvement
