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

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.

Our results showed that DRG-related costs was insufficient to make a correct economic evaluation, so we recommend an individualized cost calculating method.

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.
