Acute upper gastrointestinal bleeding secondary to aortoesophageal fistula. Endoscopic treatment using the over-the-scope clip (OTSC®) system.

Aortoesophageal fistula is an extremely rare cause of upper gastrointestinal bleeding associated with high morbidity and mortality. Early clinical suspicion, as well as correct management since diagnosis, can increase the probability of survival of this gastrointestinal emergency. We present the first case reported of an aortoesophageal fistula successfully treated with the OTSC system, representing another therapeutic option for this high-risk entity.

Evaluación económica del tratamiento quirúrgico de la obesidad / Economic evaluation of surgical treatment of obesity

INTRODUCCIÓN: La cirugía bariátrica es el mejor tratamiento de la obesidad mórbida a largo plazo. El ahorro generado por la mejoría de las comorbilidades podría justificar el empleo de más recursos sanitarios. MÉTODOS: Estudio observacional, descriptivo, longitudinal y retrospectivo, de pacientes a los que se les realizó un bypass gástrico, en el Hospital Universitario Central de Asturias entre 2003 y 2012. El seguimiento mínimo se estableció en dos años. Calculamos de manera individualizada el coste para cada uno de los pacientes intervenidos (bottom-up), así como según el grupo relacionado por el diagnóstico (GRD) (top-down). RESULTADOS: De los 307 pacientes del estudio, el coste medio del ingreso calculado por GRD fue de 6.545,9€ y el calculado por paciente de 10.572,2€. El GRD 288 representa al 91% de la serie con un valor de 4.631€. El cálculo estimativo del ahorro que supuso en nuestro entorno sanitario la disminución del número de fármacos de 2,86 a 0,78 por paciente medicado, representó 4.433€ por paciente intervenido si padecía todas las comorbilidades analizadas. CONCLUSIONES: El bypass gástrico en el Hospital Universitario Central de Asturias a los dos años de la cirugía, en pacientes con pluripatología consiguió un ahorro solo en fármacos que podría compensar los gastos inherentes al tratamiento quirúrgico. El coste por proceso mediante GRD se mostró insuficiente a la hora de hacer una correcta evaluación económica, por lo que recomendamos un método de evaluación de coste por paciente

INTRODUCTION: Obesity surgery is the best treatment for extreme obesity, with demonstrated long-term positive outcomes. The potential cost-savings generated by the improvement of comorbidities after surgery can justify the allocation of more resources in the surgical treatment of obesity. METHODS: This was an observational, descriptive, longitudinal and retrospective study. Eligible patients underwent Roux-en-Y gastric bypass surgery at the Hospital Universitario Central de Asturias between 2003 and 2012. The established minimum follow-up period was two years. We calculated the individualized cost per patient treated (bottom-up) as well as per Diagnosis-Related Group (DRG) codes (top-down). RESULTS: Our study included 307 patients. The average cost per hospitalization calculated by DRG codes was €6,545.90, and the average cost per patient was €10,572.20. DRG 288 represented 91% of the series, with a value of €4,631. The number of medications also decreased during this period, from 2.86 to 0.78 per medically treated patient, representing a cost reduction of €4,433 per patient with all the obesity-related comorbidities analyzed. CONCLUSIONS: Two years after Roux-en-Y gastric bypass conducted at Hospital Universitario Central de Asturias, the savings in drug costs for patients with multiple pathologies would compensate the inherent costs of the surgical treatment itself. Our results showed that DRG-related costs was insufficient to make a correct economic evaluation, so we recommend an individualized cost calculating method

Prospective Analysis Regarding Health-Related Quality of Life (HR-QOL) between Morbid Obese Patients Following Bariatric Surgery Versus on a Waiting List.

BACKGROUND: Major impairment of health-related quality of life (HRQoL) is one of the main reasons why obese patients request surgical treatment. OBJECTIVE: To prospectively analyze the impact of HRQoL between obese patients who underwent surgery and those who were wait-listed. METHODS: Between April 2017 and March 2018, 70 surgical and 69 wait-listed patients were interviewed twice, at baseline and at the 12-month follow-up. Quality of life was measured by the SF-12v2 and the Impact of Weight on Quality of Life-Lite (IWQoL-Lite) questionnaires. Sociodemographic-, clinical-, and surgical-related variables were collected. RESULTS: One hundred thirty-nine patients were analyzed, showing similar baseline characteristics but differences in HRQoL. Performing more qualified work improved scores on some aspects of the SF-12 survey. In contrast, women scored worse on the self-esteem domain, and men scored worse on the mental health domain. By group, at the 12-month follow-up, statistically significant differences were found among all aspects of the questionnaires between both groups (P < 0.001) and between baseline and postoperative 12-month follow-up in the surgical group (P < 0.001). Furthermore, scores were lower in all domains in the evolution of wait-listed patients, with statistically significant differences among the Bodily Pain, Emotional Role, Mental Health, and Mental Component Summary Domains (P < 0.05). CONCLUSION: HRQoL is a multimodal concept that allows the identification of factors impacting obese patients' quality of life. It promotes the benefit of surgery against waiting list delays, which can take up to 4 years in our hospital. Therefore, HRQoL is an important pillar to justify more resources for reducing unacceptable surgical delays.

Evidencia en seguimiento y pronóstico del cáncer de unión esofagogástrica / Evidence in follow-up and prognosis of esophagogastric junction cancer

La supervivencia a cinco años de los tumores de la unión esofagogástrica está en el 50% en los estadios más favorables y con los tratamientos coadyuvantes más eficaces. Más del 40% de los pacientes sufrirá recurrencias en un periodo breve, habitualmente en el primer año tras una cirugía potencialmente curativa y la supervivencia tras esa recurrencia suele ser menor de 6 meses, pues el tratamiento es poco eficaz, sea quimioterapia paliativa, radioterapia o exéresis quirúrgica de las recidivas únicas. El tipo y frecuencia del seguimiento realizado influye en la supervivencia porque la detección de recurrencias asintomáticas permite realizar tratamientos más precoces y efectivos

Five-year survival of tumors of the esophagogastric junction is 50%, in the most favourable stages and with the most effective adjuvant treatments. More than 40% of patients will have recurrences within a short period, usually the first year after potentially curative surgery. Survival after this recurrence is usually less than 6 months because treatment is not very effective, be it palliative chemotherapy, radiotherapy or surgical excision of single recurrences. As the detection of asymptomatic recurrences allows for earlier and more effective treatments to be used, the type and frequency of follow-up has an influence on survival

Laparoscopic treatment of large bowel obstruction due to a self-locating peritoneal dialysis catheter.

INTRODUCTION: Peritoneal dialysis has been used in the treatment of end-stage renal disease for a long time. The development of continuous ambulatory peritoneal dialysis (CAPD) has achieved an acceptable device of renal replacement therapy. PRESENTATION OF CASE: We report a 55 year-old patient who was initiated on CAPD in February 2016. Three months later, the Tenckhoff catheter was removed due to its malfunction, and a new self-locating peritoneal dialysis catheter was placed in the left side of the abdomen. In September 2016, the patient presented with symptoms of intestinal obstruction. A CT scan revealed a collapsed sigmoid colon with the tungsten tip of the catheter supported on the mesosigmoid as the cause of the occlusion. DISCUSSION: Herein, a rare but clinically important case of mechanical large bowel obstruction due to self-locating peritoneal dialysis catheter is presented. The weight added to the tip of the self-locating catheter for the purpose of stretching it, can be dangerous if a displacement takes place. A laparoscopic procedure was performed, resolving the obstruction by reinserting the peritoneal catheter in its right position. CONCLUSION: The weight added to the tip of self-locating catheters is a matter of concern, since intimate contact between the peritoneal catheter and the intestinal wall can result in perforation or intestinal occlusion.

¿Mejora la incorporación de un simulador virtual las capacidades en cirugía endoscópica adquiridas con simuladores inanimados? / Does the incorporation of a virtual simulator improve abilities in endoscopic surgery acquired with an inanimate simulator?

Se ha generalizado la realización de cursos y programas de formación en cirugía endoscópica en centros de entrenamiento. Además de una adecuada planificación de las actividades, se deben introducir sistemas de simulación para el aprendizaje y monitorizar la progresión. Se valoró la mejor adquisición de capacidades en un programa de formación en cirugía endoscópica al incorporar un simulador virtual a la práctica con cajas de entrenamiento. Material y método Se incluyó a 17 médicos residentes con un registro basal: grupo control. Se constituyeron 2 grupos: el grupo A, con 6h de entrenamiento con simulador inanimado, y el grupo B, con lo mismo más 4h de prácticas con LapSim. Se planificaron ejercicios de movilización-desplazamiento de objetos, corte y sutura-anudado en el simulador simple y en el virtual. Se evaluó el tiempo (medias e intervalos de confianza del 95%) empleado en cada ejercicio sobre el simulador inanimado, antes y después del entrenamiento. ResultadosEjercicio de movilización: el tiempo del grupo control fue de 223,6s, el del grupo A fue de 103,7s y el del grupo B fue de 89,9s (grupo control frente al grupo A, p<0,05). Ejercicio de corte: el tiempo del grupo control fue de 317,72s, el del grupo A fue de 232,8s y el del grupo B fue de 163,6s, (grupo control frente al grupo B, p<0,05). En el ejercicio de sutura todos consiguen dar un punto tras el entrenamiento. El tiempo del grupo control fue de 518,4s, el de A fue de 309,4s y el de B fue de 189,5s (grupo control frente al grupo A, p<0.05).Conclusiones El entrenamiento con simulador inanimado consiguió mejorar tanto el tiempo de movilización como el de sutura-anudado con respecto al grupo control. La incorporación del simulador virtual ha logrado superar los resultados obtenidos, sobre todo en el corte (AU)

Introduction The carrying out of training courses in surgical endoscopy for surgeons in training centres, is becoming more common. In addition to adequately planning activities, simulation systems are used to improve learning and monitor progression. Inanimate models and virtual reality programs increase psychomotor skills and assessment of performance. In this work we tried to improve our training program, basically in training boxes by introducing a virtual simulator. Material and method Seventeen surgical residents, with a basic training were chosen as the control group. Two additional groups were established, group A: with 6 hours of training with inanimate simulator. Group B: the same training system plus 4h of practice with LapSim. Exercises in the endotrainer and virtual simulator with moving-replacing objects, cutting and suturing-knotting were planned. End-point was time (mean with 95% confidence interval) in every exercise in box trainer, before and after the training period. Results Movement exercises: Time in control group was 223.6s, A:103.7s, and B:89.9s (Control vs. A, p<0,05). Cutting exercises: Time in control group was 317.7s, group A: 232.8s and in the B: 163.6s, (Control vs. B, p<0.05). In the suture/knot exercise everyone was able to carry out a stitch after the training period. Time in control group was 518.4s, in group A: 309.4s, p<0.05, and in B:189.5s (Control vs. A, p<0.05).Conclusions Training in inanimate boxes was able to improve the skills of students, particularly for moving and suture/knots.

[Integral management of the process of laparoscopic cholecystectomy]. / Gestión integral del proceso de colecistectomía laparoscópica.

INTRODUCTION: One of the most important objectives of public healthcare services is to guarantee integral healthcare to patients; activity is currently focussed on process management. Analysis of a "key" process could have health, social and economic effects if measures to improve the results are designed. The aim of the present study was to evaluate the process of laparoscopic cholecystectomy in our hospital in order to determine its strong and weak points. MATERIAL AND METHOD: We performed a prospective observational study of the laparoscopic cholecystectomy (LC) process in the Jarrio Hospital between January 2001 and December 2002. A working group was formed and a process flowchart was designed by consensus. The different steps of the process were evaluated through the main indicators of quality: accessibility, efficiency, and effectiveness, including cost, the convalescence period, and patient satisfaction. The results were compared with the standards defined by the Andalusian Health Council, bibliographic sources, and hospital commissions. The statistical analysis was performed with 95% confidence intervals of the main results. RESULTS: A series of 86 patients who underwent LC was evaluated. The results for accessibility showed wide variability in delays for specialist consultations, the waiting list for surgery, and urgent diagnostic tests, often exceeding the standards. The laparoscopic approach was more frequent than open cholecystectomy; morbidity and mortality with LC were below the reference standards and compliance with established prophylaxis protocols was close. The efficiency markers showed that the length of hospital stay for elective LC was close to the standard; however, for cholecystitis preoperative length of stay was longer than the standard. Overall patient satisfaction with medical care and non-medical services was high. CONCLUSIONS: Quality analysis of a process allowed us to identify strong points such as the high rate of laparoscopic cholecystectomy -showing good effectiveness and efficiency- the quality of informed consent, and patient satisfaction. Required improvements consisted of shortening preoperative length of stay in acute cholecystitis and waiting lists, informing patients about the length of the convalesce period, eliminating routine type and screen, and admitting patients on the day of surgery.
