Análisis de la pérdida ponderal a medio plazo después del bypass gastroyeyunal en Y de Roux y de la gastrectomía vertical: propuesta de gráficos de percentiles del porcentaje de peso total perdido para su uso en la práctica clínica diaria / Analysis of mid-term weight loss after Roux-en-Y gastric bypass and sleeve gastrectomy: Proposed percentile charts for total weight loss percentages to be used in daily clinical practice

Introducción: El objetivo de este trabajo es analizar la evolución ponderal de las principales técnicas quirúrgicas bariátricas (bypass gastroyeyunal en Y de Roux [BPGY] y gastrectomía vertical [GV]) realizadas en un conjunto representativo de centros nacionales españoles, con el fin de confeccionar unos gráficos de percentiles del porcentaje de pérdida total de peso perdido durante los 3 primeros años después de la cirugía. Métodos: Se realiza un estudio de cohortes longitudinal retrospectivo a partir de los datos aportados por 9 centros hospitalarios españoles. Se han analizado los datos ponderales tanto en porcentaje de pérdida total de peso perdido como en porcentaje de exceso de peso perdido correspondientes al BPGY (n = 1.887) y a la GV (n = 1.210). Resultados: El BPGY sigue siendo la técnica más frecuentemente realizada en nuestra muestra nacional. En ambas técnicas quirúrgicas, la pérdida de peso máxima se produce a los 18 meses de la cirugía. Ambas técnicas siguen la misma evolución ponderal, aunque los valores del porcentaje de pérdida total de peso perdido sean inferiores en el caso de la GV a los 36 meses (29,3 ± 10 vs. 33,6 ± 10). La edad y el género son determinantes en los resultados ponderales (mejores en paciente más jóvenes para ambas técnicas y mejores en mujeres para el BPGY). Conclusiones: Los gráficos de percentiles del porcentaje de peso total perdido después de la cirugía bariátrica representan una herramienta muy útil y un avance importante en la calidad asistencial para el seguimiento ponderal del paciente

Introduction: The aim of this study is to analyze weight evolution after the main bariatric surgical techniques (Roux-en-Y gastric bypass [RYGB] and sleeve gastrectomy [SG]) performed at a representative sample of Spanish hospitals in order to develop percentile charts for the percentage of total weight loss during the first 3 years after surgery. Methods: A retrospective longitudinal cohort study was conducted based on the data provided by 9 Spanish hospitals. Weight data were analyzed both in % total weight loss and % excess weight lost corresponding to the RYGB (n = 1,887) and SG (n = 1,210). Results: RYGB continues to be the most frequently performed technique in our sample. In both surgical techniques, maximum weight loss occurred 18 months after surgery. Both techniques followed the same weight evolution, although the % total weight loss values were lower in the case of the SG after 36 months (29.3 ± 10 vs. 33.6 ± 10). Age and gender are decisive in the weight results (better in younger patients for both techniques and better in women for RYGB). Conclusions: Percentile charts of % total weight loss after bariatric surgery represent a very useful tool and an important advance in the quality of patient management

New laparoscopic assisted percutaneous gastrostomy. Description and comparison with others gastrostomy types.

INTRODUCTION: Gastrostomy feeding tube insertion has become a common procedure as it enables patients who require long term enteral feeding. Conventional surgical gastrostomies were the only way of gaining enteral access in patients in which it is not possible to pass an endoscope or a nasogastric tube required for endoscopic or radiological gastrostomies, and in patients in which certain anatomical abnormalities contraindicate performing these techniques. As conventional surgical gastrostomies are associated with high morbidity, especially gastric leakage around the tube, percutaneous laparoscopic assisted gastrostomy (PLAG) may be a better way to gain enteral access. MATERIAL AND METHODS: Observational study of a prospective cohort of 224 patients on whom a gastrostomy was performed for nutritional support between January 2009 and October 2015 at Virgen del Rocío University Hospital in Seville. The types of gastrostomies carried out were: percutaneous endoscopic gastrostomy (PEG, n = 106), percutaneous radiological gastrostomy (PRG, n = 89), conventional surgical gastrostomy, Open Stamn or Laparoscopic Janeway (SG, n = 9) and percutaneous laparoscopic assisted gastrostomy (PLAG, n = 20), technique that we describe in detail. Short and long term complications are described. RESULTS: Many more complications were seen in the conventional gastrostomy group than in the other three groups, especially leakage of gastric content around the tube, with burning and irritation of the skin (66% compared with 2.83% in PEG and 0% in PLAG and PRG). The group with the highest proportion of patients completely free of complications was PLAG (75%), whilst in the conventional surgical gastrostomy group, no patient was completely free of complications. CONCLUSIONS: We found lower complication rate in PLAG than any other technique. We believe that PLAG could be preferred technique for patients on whom it is not possible to perform PEG or PRG, as it is safe and easy.

[Bariatrica paraplegia patient and morbid obesity. New challenge in bariatric surgery]. / Paciente con paraplejia y obesidad mórbida; nuevo reto en la cirugía bariátrica.

The loss of mobility due to spinal cord injury is a risk factor for weight gain. Despite the well-documented outcomes of bariatric surgery in outpatients, little information is available about the surgery in paraplegic patients. We present two cases of patients with morbid obesity and spinal cord injury. After several attempts to lose weight conservatively, were assessed by the multidisciplinary team of our hospital and finally intervened by laparoscopic gastric bypass. After surgery have been no post-surgical complications. The patient in case 1, after two years of follow-up, a weight of 84 kg (BMI 25.08 kg/m2). Case 2, after a month of surgery has reduced weight and stopped taking antihypertensive therapy. It 's available to bariatric surgery as an important option to consider if all non-surgical interventions fail is highlighted.

La pérdida de la movilidad, como consecuencia de una lesión medular, es un factor de riesgo para el aumento de peso. A pesar de los resultados bien documentados de la cirugía bariátrica en pacientes ambulatorios, hay poca información disponible acerca de la cirugía en pacientes parapléjicos. Presentamos dos casos clínicos de pacientes con obesidad mórbida y lesión medular. Tras varios intentos para perder peso de forma conservadora, fueron valorados por el equipo multidisciplinar de nuestro hospital y finalmente se intervinieron mediante bypass gástrico por vía laparoscópica. El caso 1, tras dos años de seguimiento, presenta un peso de 84 kg (IMC 25,08 kg/m2). El caso 2, tras un mes de la cirugía ha reducido de peso y ha dejado de tomar tratamiento hipotensor. En ellos, destaca la disposición de la cirugía bariátrica como una opción a tener en cuenta si todas las intervenciones no quirúrgicas fracasan.
