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.

Prevalence of endodontic infection in patients with Crohn´s disease and ulcerative colitis.

BACKGROUND: Previous studies have linked apical periodontitis (AP) to inflammatory bowel disease (IBD). The aim of this study was to compare the prevalence of AP and root canal treatment (RCT) in patients with ulcerative colitis (UC) and Crohn´s disease (CD). MATERIAL AND METHODS: A cross-sectional study, including 28 patients with Crohn´s disease and 26 with ulcerative colitis, was conducted. AP was diagnosed as radiolucent periapical lesions (RPLs), using the periapical index score (PAI). Student's t test, 2 test and multivariate logistic regression were used in the statistical analysis. RESULTS: Multivariate logistic regression run with age, gender, number of teeth, number of RFT, periodontal disease and the type of IBD as covariates, taking as dependent variable and outcome "periapical status" (0 = no tooth with RPL; 1 = at least one tooth with RPL), showed that both UC and CD patients had the prevalence apical periodontitis (OR = 1.03; C.I. 95% = 0.25 - 4.31; p = 0.97). The multivariate analysis, including all the above covariates, shows that both in UC and CD patients the prevalence of RCT was similar (OR = 0.76; C.I. 95% = 0.17 - 7.31; p = 0.73). Periapical status was significantly associated with endodontic status (OR = 42.72; C.I. 95% = 3.87 - 472.15; p = 0.002), regardless of IBD type. CONCLUSIONS: The results of the present study show similar frequency of AP and RFT in both UC and CD patients. The type of IBD does not appear to affect the prevalence of radiographically detectable periapical lesions or the prevalence of root canal treatment.

Hepatic resection and blood transfusion increase morbidity after cytoreductive surgery and HIPEC for colorectal carcinomatosis.

BACKGROUND AND OBJECTIVES: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is an effective but complex treatment for peritoneal metastasis (PM). Our objective was to identify risk factors for postoperative morbidity and mortality following CRS-HIPEC. METHODS: Retrospective study of prospectively collected data of patients undergoing CRS-HIPEC for PM arises from colorectal cancer between January 2008 and December 2017. Perioperative variables were correlated with morbidity outcomes using a logistic regression model. RESULTS: Sixty-seven patients underwent CRS-HIPEC, and overall morbidity and mortality were 31.3% and 4.5% respectively. Major morbidity rate was 19.4%; 7.5% of patients were re-operated. Intraoperative blood transfusion (p = 0.01), liver resection (p < 0.01), and intestinal anastomosis (p < 0.01) were associated with a higher morbidity in univariate analysis. A multivariate analysis identified blood transfusion and liver resection as independent risk factors (OR 3.66, IC 1.13-16.54; OR 4.33, IC 1.17-11.46, respectively). Extension of visceral resection did not correlate with morbidity. Patients with lymph-node infiltration had a higher major complication rate (p = 0.01). CONCLUSIONS: CRS-HIPEC is a feasible treatment for colorectal PM with an acceptable morbi-mortality rate in experienced centers. In our study, digestive anastomosis, perioperative blood transfusion, hepatic resection, and lymph-node infiltration were associated with higher morbidity rates.

Goal-directed therapy in cytoreductive surgery with hyperthermic intraperitoneal chemotherapy: a prospective observational study.

BACKGROUND: Cytoreductive surgery (CRS) with Hyperthermic Intraperitoneal Chemotherapy (HIPEC) in peritoneal carcinomatosis treatment causes significant hemodynamic, metabolic, and hematological alterations. Studies on the anesthetic intraoperative management are heterogeneous and scarce. There is a great heterogeneity in the anesthetic management of CRS and HIPEC. The aim of this study is to analyze perioperative hemodynamic goal-directed management and to evaluate the complications arisen until the seventh postoperative day. METHODS: Prospective, observational study of all CRS and HIPEC patients from March 2014 to May 2017. Hemodynamic and clinical parameters were registered during surgery and the first 3 postoperative days. We correlated intraoperative data with the postoperative course until the seventh day. RESULTS: A total of 92 patients were included in the study (age 58.5 ± 10.9 years, 47% colorectal carcinoma, and 38% ovarian carcinoma). Peritoneal Carcinomatosis Index (PCI) (median and ranges) was 10 [0-39]. Cardiac Index (CI) 3.15 l/min-1/m-2 [1.79-5.60]) and Systolic Volume Variation (SVV) (10% [3%-17%]) remained within the values of normality in all surgery phases. A large difference was observed between the minimum and maximum ranges of fluid therapy administered (median 9.8 ml/kg/h [5.3-24.3]), showing a great interindividual variation in the fluids requirement. A direct relationship was observed between PCI and surgery duration, fluid therapy, and intraoperative transfusion percentage (p < 0.02). CONCLUSIONS: There is a great variability in the intraoperative fluid therapy needs of the patients. SVV monitoring makes it possible to adjust the fluid therapy needs in each surgery phase. The use of a hemodynamic goal-directed anesthetic protocol in CRS and HIPEC enables to individually adjust the fluid therapy, avoiding over-hydration and ensuring hemodynamic stability in all surgery phases.

Treatment of transsphincteric fistula-in-ano with growth factors from autologous platelets: results of a phase II clinical trial.

PURPOSE: The aim of this paper is to evaluate to the safety, feasibility and efficacy of a novel treatment for transsphincteric cryptoglandular fistula: injection of autologous plasma rich in growth factors (PRGF) into the fistula tract accompanied by sealing using a fibrin plug created from the activated platelet-poor fraction of the same plasma. METHOD: This article is a prospective, phase II clinical trial. The procedure was externally audited. Thirty-six patients diagnosed with transsphincteric fistula-in-ano were included. All patients underwent follow-up examinations at 1 week and again at 3, 6 and 12 months after discharge. Main outcome measures safety (number of adverse events), feasibility and effectiveness of the treatment. RESULTS: A total of 36 patients received the study treatment, with the procedure found to be feasible in all patients. A total of seven adverse events (AE) related to the injected product or surgical procedure were identified in 4 of 36 patients. At the end of the follow-up period (12 months), 33.3% of patients (12/36) had achieved complete fistula healing and 11.1% of patients (4/36) had achieved partial healing. In total, this amounted to 44.4% of patients (16/36) being asymptomatic at final follow-up. In successfully healed patients, a gradual reduction in pain was observed, as measured using a Visual Analog Scale (VAS) (p = 0.0278). Compared to baseline, a significant improvement in Wexner score was seen in patients achieving total or partial healing of the fistula (p = 0.0195). CONCLUSIONS: The study treatment was safe and feasible, with apparently modest efficacy rates. Continence and pain improvement following treatment may be considered predictive factors for healing.

Is the interval from surgery to ileostomy closure a risk factor for low anterior resection syndrome?

AIM: Low anterior resection syndrome (LARS) comprises a collection of symptoms affecting patients after restorative surgery for rectal cancer. The aim of the present study was to analyse the incidence of LARS in patients undergoing rectal cancer surgery with and without subsequent ileostomy and to determine whether the interval to ileostomy closure is a factor associated with its occurrence. METHOD: All patients undergoing curative anterior resection for rectal cancer from 2008 to 2012 in our institution were included in the study. They were divided into two groups according to whether or not a defunctioning ileostomy had been performed. Patients were assessed for LARS at a median interval of 23.60 ± 16.73 (12-48) months from anterior resection in those who did not have an ileostomy and at an interval of 11.31 ± 14.24 (12-60) months from closure of the ileostomy in those who did. They underwent a structured telephone interview based on a validated LARS score questionnaire. Univariate and multivariate analysis was carried out to assess possible associations between LARS and the variables studied. RESULTS: There were 150 patients (93 men) of whom 54.7% had no evidence of LARS, 17.3% had minor symptoms and 28% major symptoms of LARS. Univariate analysis showed that male gender, the presence of a temporary ileostomy and neoadjuvant therapy were predisposing factors for LARS. The interval from construction of the ileostomy to its closure did not appear to be a factor associated with LARS. In multivariate analysis, male gender and preoperative neoadjuvant therapy were significant predisposing factors for LARS. CONCLUSION: Male gender and preoperative neoadjuvant therapy are risk factors for LARS. The presence of ileostomy or time to ileostomy closure is not associated with the development of this syndrome.

Prevalidación de un test de equilibrio en tiro olímpico sin armas / Prevalidation of body sway shooting test without the use of weapons

El principal objetivo de este estudio es realizar un estudio previo a la validación de un test de medición del equilibrio en tiro olímpico sin el uso de la pistola. Para ello, se han comparado los resultados del análisis del movimiento del centro de presiones (CP) de dos pruebas de equilibrio estático: en la primera prueba se usó una mancuerna para simular la acción de disparo, mientras que en la segunda se usó la pistola. Se encontró una fuerte correlación entre los dos test en todas las variables del CP y una correlación lineal inversa entre el peso corporal y los movimientos del CP. No se encontró relación alguna entre los movimientos del CP y el rendimiento deportivo. El estudio concluye que el test con mancuerna puede ser válido para la medición del equilibrio específico en tiro olímpico y se recomienda profundizar en el estudio con una muestra de mayor tamaño (AU)

The main objective of the present work is the pre-validation of a test able to provide reliable body sway measurements in Olympic shooting, without the use of a pistol. For this reason the results of the analysis of the body sway data of two static bipodal balance tests have been compared: during the first a dumbbell was used to simulate shooting, while for the second test a pistol was used. A strong correlation between the two tests regarding all variables was found. A statistically significant inverse linear correlation was also found between body weight and the movements of the COP (centre of pressure). No statistically significant relations were found between the movements of the COP and performance. The study concludes that dumbbell tests could be perfectly reliable for measuring specific body sway on Olympic shooting. Future studies on the validation of the same test with larger sample size are recommended (AU)

Inter-operator reliability of Videobserver(TM) / Validación Inter-operador de Videobserver(TM) / Validação Inter-operador de Videobserver(TM)

The purpose of this study was to evaluate the degree of interobserver reliability for the sport analysis company VIDEOBSERVER(TM). The football match corresponding to the 2014 World Cup final was used as the sample for the study. Data were collected on 28 players, including the actions of the goalkeepers and the players substituted during the match. This study was carried out in four phases: (i) a revision of the literature was performed to define the theoretical frame-work and the procedures to be followed; (ii) an observation system was created with the help of two experienced sports analysis technicians; (iii) a pilot study was carried out with the aim of verifying the operativity of the observation system; and (iv) the main study of inter-observer reliability was developed. The values of the kappa index, the standardized typical error and the intra-class correlation coefficient were used for the statistical analysis. The results showed a high level of inter-operator reliability, a statement which is supported by the high values of the intra-class correlation coefficient (both at the individual and collective level) and the small standardized typical error which were found in this study. This study adds an innovative element of analysis consisting in the fact that the evaluation was carried out not only at the collective level but also at the individual level (AU)

Outcomes of Liver Transplantation During Adulthood After Kasai Portoenterostomy Due to Biliary Atresia.

Biliary atresia (BA) is a neonatal progressive cholangiopathy of unknown etiology and one of the most common reasons for liver transplantation (LT) in children. Kasai portoenterostomy (KP) improves survival of the native liver, although LT remains the only ultimate treatment. In some cases KP makes it possible to defer the ultimate LT until adulthood. We report our experience regarding 5 cases of BA treated with LT during adulthood. KP was performed in all patients at an average age of 176 days (range, 60-280), which allowed an average survival of the native liver of 19.01 years (range, 14.06-22.32). Five-year survival rate was 100%. Ten-year survival rate did not reach 100% because of a death 9.55 years after LT due to chronic graft rejection, in a patient who was already prepared for a new LT. Our results corroborate that KP remains the first-line treatment of BA. Early performance of the KP provides children with the best chance of survival, allowing the delay of the LT to adulthood. LT during adulthood in these patients achieves good post-LT survival rate; we have not found any data regarding this group of patients in the literature.

Análisis antropométrico de la simetría corporal en jugadores de bádminton / Anthropometric analysis of body symmetry in badminton players

El objetivo del estudio fue comprobar si existen diferencias entre el lado dominante y no dominante de las medidas antropométricas en los mejores jugadores y jugadoras españoles de bádminton, así como verificar si el lado del cuerpo donde se realiza la medición puede influir en el cálculo de la composición corporal y del somatotipo. Participaron voluntariamente en el estudio 46 jugadores de bádminton de élite, 31 eran hombres (edad=21,7+/-4,3 años) y 15 mujeres (edad=19,1+/-4,4 años). Se tomaron las medidas de 6 pliegues cutáneos, 3 diámetros, 3 longitudes y 5 perímetros del lado dominante y no dominante de los sujetos. Se calculó la composición corporal y el somatotipo con los valores registrados en cada uno de los lados. No se encontraron diferencias en los pliegues ni en las longitudes entre el lado dominante y no dominante, como consecuencia tampoco se encontraron diferencias significativas en el porcentaje de grasa (dominante=11,20+/-4,45 por ciento; no dominante=11,12+/-4,48 por ciento; ns). Aparecieron valores superiores (p<0,05) en los diámetros óseos y en los perímetros en el lado dominante. El porcentaje óseo fue mayor calculado a partir de las mediciones del lado dominante (dominante=16,37+/-1,14 por ciento, no dominante=15,66+/-1,12 por ciento; p<0,001). El porcentaje muscular fue mayor calculado a partir de las mediciones del lado no dominante (dominante=49,39+/-2,60 por ciento, no dominante=50,18+/-2,69 por ciento; p<0,001). Como conclusión podemos afirmar que existen asimetrías corporales en los jugadores de bádminton de alto nivel, al encontrarse diferencias en los diámetros óseos y en los perímetros entre el lado dominante y no dominante. Al calcular la composición corporal con el lado dominante de los jugadores de bádminton se está sobreestimando el porcentaje óseo e infraestimando el porcentaje muscular...

The purpose of this study was to determine whether differences exist between the dominant and non-dominant side in anthropometric measurements in the best Spanish badminton players, and to verify if the side of the body where the measurement was made could influence the calculation of body composition and somatotype. Forty-six elite badminton players voluntarily participated in the study, 31 were men (age=21.7+/-4.3 years) and 15 women (age=19.1+/-4.4 years). Anthropometric measurements consisting of 6 skinfolds, 3 lengths, 3 breadths and 5 girths, were taken on the dominant and non-dominant side of each participant. Body composition and somatotype were calculated with the values ??recorded on each side. No differences were found in the skinfolds or the lengths between the dominant and non-dominant side, as a result neither were significant differences found in the fat percentage (11.20 +/- 4.45 percent dominant; 11.12 +/- 4.48 percent, non-dominant, ns). Values were higher (p <0.05) in bone breadths and girths on the dominant side. Bone percentage was greater when calculated from measurements on the dominant side (dominant=16.37+/-1.14 percent, non-dominant=15.66+/-1.12 percent; p<0.001). Muscle percentage was higher when calculated from measurements on the non-dominant side (dominant=49.39+/-2.60 percent, non-dominant=50.18+/-2.69 percent; p<0.001). In conclusion we can confirm that there are body asymmetries in high level badminton players, because differences were found in bone breadths and girths between the dominant and non-dominant side. When calculating the body composition with the badminton players' dominant side, bone percentage was overestimated and muscle percentage was underestimated...

Walled-off pancreatic necrosis.

Acute severe pancreatitits may be complicated by the development of 'walled-off pancreatic necrosis' (WOPN), which is characterised by a mixture of solid components and fluids on imaging studies as a consequence of organised pancreatic tissue necrosis. We present here an overview of the definition, clinical features, and diagnostic and therapeutic management of this clinical condition, which is mostly based on consensus as adequate clinical trials are lacking.

Prognostic value of the ankle-brachial index in elderly patients with a stable chronic cardiovascular event.

BACKGROUND AND OBJECTIVES: Patients with polyvascular arterial disease have a greater risk of suffering a new atherothrombotic episode than those with involvement of only one vascular territory. We have studied the predictive prognostic value of the detection of non-diagnosed peripheral arterial disease, determined by measuring the ankle-brachial index in a population of elderly patients with stable chronic cardiac or cerebrovascular disease. METHODS: This was a multicenter, prospective cohort study with consecutive inclusion of patients between 65 and 85 years of age with a previous atherothrombotic event, but without previously established peripheral arterial disease. RESULTS: A total of 1096 patients were evaluated during 11.7 (+ or - 2.2) months of follow-up. An ankle-brachial index of < 0.9 was observed in 29.9% and > 1.4 in 6.9%. The detection of an ankle-brachial index < 0.9 was clearly associated with the presence of a combined primary event of cardiovascular death and non-fatal cardiovascular event [HR 1.99 (95% CI, 1.49-2.66; P < 0.001)]. There was also a significant relationship between ankle-brachial index > 1.4 and total (P = 0.001) or cardiovascular (P = 0.020) deaths. The predictive value of both ranges of the ankle-brachial index was maintained after adjusting for age, sex, diabetes mellitus, vascular territory, macroalbuminuria or glomerular filtration rate. CONCLUSIONS: The detection of non-diagnosed peripheral arterial disease in patients with stable coronary or cerebrovascular events identifies a very high risk population that might benefit from more intensive treatment.

La transición deportiva de junior a senior en jugadores de baloncesto / No disponible

El objetivo del presente artículo es conocer que factores afectan a los jugadores de baloncesto en la transición deportiva que se produce cuando pasan del baloncesto amateur y junior al baloncesto profesional y senior. Por transición, se entiende cualquier suceso que acarrea una modificación en la concepción de uno mismo y del mundo, lo cual requiere del correspondiente cambio en la forma de comportarse y relacionarse de uno mismo (Schlossberg, 1981). Hasta el momento, la transición más estudiada es la finalización de la vida deportiva (e.g.; Gónzalez & Bedoya, 2008). Son pocos los estudios que analizan las transiciones durante la carrera deportiva. En baloncesto, Čačija (2007), destacó como factores de carácter deportivo: a) la exigencia física de los entrenamientos; b) tener que demostrar constantemente su capacidad; c) una mayor exigencia mental; d) un nuevo tipo de relación con el entrenador; v) tener menor responsabilidad dentro del equipo; y e) vivir en un entorno más reglado. Además, los jugadores también experimentaron nuevas exigencias fuera del contexto deportivo como: a) tener que priorizar y planificarse mejor; b) cambios de lugar de residencia; c) los estudios universitarios; y d) el entorno cambiante del alto rendimiento. Para superar dichas exigencias, los jugadores fundamentalmente se apoyaron en su red social, en sus características individuales, en el apoyo económico, y en otras actividades fuera del ámbito deportivo (AU)

Análisis de la decisión táctica en el bloqueo directo. Una comparación entre selecciones internacionales absolutas y clubes / No disponible

Actualmente el bloqueo directo es una de las acciones más habituales es su utilización dentro de los sistemas ofensivos de los equipos de baloncesto (Ivanovic, 2006), y en contrastre una de las menos atendidas por la investigación, existiendo escasos estudios sobre esta opción de ataque. Concerniente a la toma de decisión en baloncesto destacamos los trabajos de Bar-Eli & Tracktinsky (2000) los cuales determinaron como la calidad de la decisión disminuía ante situaciones críticas, y Busemeyer & Townsend (1993) los cuales desarrollaron el Decision Field Theory para facilitar la compresión de la decisión en situaciones deportivas. En el presente estudio realiazamos un análisis y comparación en el uso del bloqueo directo por parte de las selecciones internacionales absolutas y clubes pertenecientes a la ACB, para así determinar las diferencias existentes en ambas categorias (AU)

Una herramienta de apoyo a la docencia: DVD didáctico para la enseñanza del baloncesto y del baloncesto en silla de ruedas / No disponible

El análisis de los deportes es un requisito fundamental a la hora de diseñar las situaciones de aprendizaje en los mismos. Normalmente este análisis viene de la mano del estudio de las acciones de juego tanto en ataque como en defensa, el rol específico de los jugador/es en el campo de juego, así como del análisis de las dimensiones tácticas, técnicas y estratégicas del propio juego. El objetivo del profesorado del Grupo de Innovación Educativa “Deportes Colectivos” de la Facultad de Ciencias del Deporte - INEF (Universidad Politécnica de Madrid) ha sido la creación de un DVD didáctico que favorezca la adquisición de conocimientos del alumnado en asignaturas relacionadas con la iniciación a los deportes. Los objetivos de este estudio han sido: a) estructurar y desarrollar una base común y específica en la enseñanza y aprendizaje de la iniciación a determinados deportes colectivos (baloncesto, fútbol y baloncesto en silla de ruedas); b) seleccionar y editar el material audiovisual específico de los deportes colectivos seleccionados y c) diseñar y elaborar el citado DVD (AU)
