Obesidad y SARS-CoV-2: consideraciones sobre la cirugía bariátrica y recomendaciones para el inicio de la actividad quirúrgica / Obesity and SARS-CoV-2: Considerations on bariatric surgery and recommendations for the start of surgical activity

La pandemia SARS-CoV-2 ha tenido un gran impacto en todo el mundo, siendo España uno de los países más afectados. La demora en la cirugía bariátrica puede tener consecuencias fatales, ya que hasta el 50% de los pacientes que se encuentran en lista de espera desarrollan una nueva comorbilidad durante el tiempo que permanecen en ella y el 1,5% de pacientes fallecen mientras esperan la intervención. Es por ello por lo que la cirugía bariátrica no debe demorarse en cuanto la ocupación del hospital por pacientes COVID-19+ disminuya de forma significativa y se disponga de recursos y seguridad suficiente para realizar la cirugía en pacientes con patología benigna. Este documento recoge las principales recomendaciones para los programas de cirugía bariátrica en nuestro país desde el punto de vista tanto de seguridad como de preparación y seguimiento del paciente bariátrico en el contexto de la pandemia SARS-CoV-2

The SARS-CoV-2 pandemic has a great impact worldwide, being Spain one of the most affected countries. The delay in bariatric surgery can have fatal consequences since up to 50% of the patients who are on the waiting list develop a new comorbidity during the time they remain on it and 1.5% of patients die while waiting for the intervention. That is why bariatric surgery should not be delayed, if the occupation of the hospital by COVID-19+ patients decreases significantly, and sufficient resources and safety are available to restart surgery in patients with benign pathology. This document contains the main recommendations for the bariatric surgery programs in our country from the point of view of safety, bariatric patient preparation and follow up during the SARS-CoV-2 pandemia

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
