[Influence of the lockdown due to COVID-19 on weight-loss results during the first year after sleeve gastrectomy]. / Influencia del confinamiento por COVID-19 en los resultados ponderales durante el primer año tras la gastrectomía vertical.

INTRODUCTION: COVID-19 pandemic has lead to lockdown of population in many countries. In Spain, the state of alarm was established from March 15 to June 20, 2020. Usually this fact decreased people's mobility and physical activity, in addition to producing or exacerbating psychological disorders. Our aim was to determine the influence that this condition had over the short-term ponderal results of patients undergoing laparoscopic vertical gastrectomy from May 2019 to May 2020. METHODS: Case-control study for comparing the percentage of excess weight lost (%EWL) and the percentage of total weight lost (%TWL) of patients that underwent a VG during the last year, so they were affected by lockdown in April and part of March 2020 (group 1), to the %EWL and %TWL of a control group (group 2), obtained from our previous series. RESULTS: The mean %EWL in group 1 is 47,37 ± 18,59 and in group 2 is 51,13 ± 17,59, being p = 0,438. Meanwhile, the mean %TWL in group 1 is 21,14 ± 8,17 and in group 2 is 24,67 ± 8,01, with p = 0,115. CONCLUSIONS: Population lockdown by COVID-19 did not get worse short-term results of vertical gastrectomy. More studies with a larger number of patients are necessary to draw firm conclusions.

Influencia del confinamiento por COVID-19 en los resultados ponderales durante el primer año tras la gastrectomía vertical / Influence of the lockdown due to COVID-19 on weight-loss results during the first year after sleeve gastrectomy

Introducción: La pandemia por COVID-19ha obligado al confinamiento de la población en muchos países. En España, el estado de alarma se estableció desde el 15 de marzo al 20 de junio del 2020. Este hecho, por lo general, disminuyó la movilidad y la actividad física de las personas, además de producir o exacerbar alteraciones psicológicas. Nuestro objetivo es analizar la influencia que esta situación ha ejercido sobre los resultados ponderales a corto plazo de los pacientes tratados mediante una gastrectomía vertical laparoscópica entre mayo del 2019 y mayo del 2020. Métodos: Estudio de casos y controles donde se compararon el porcentaje de exceso de peso perdido (%EWL) y el porcentaje de peso total perdido (%TWL) de los pacientes intervenidos en el último año y a los que ha afectado el confinamiento durante el mes de abril y parte de marzo del 2020 (grupo 1; n=20), con el de un grupo control (grupo 2; n=40) de nuestra casuística previa. Resultados: El %EWL medio en el grupo 1 es de 47,37±18,59 y en el grupo 2 es de 51,13±17,59, siendo la p=0,438. Por su parte, el %TWL medio en el grupo 1 es de 21,14±8,17 mientras que en el grupo 2 es de 24,67±8,01, resultando la p=0,115. Conclusiones: El confinamiento de la población por COVID-19 no empeoró los resultados ponderales a corto plazo de la gastrectomía vertical. Son necesarios más estudios con un mayor número de pacientes para obtener conclusiones más sólidas. (AU)

Divertículos epifrénicos: ¿cuándo y cómo operar? / Epiphrenic diverticula: when and how to operate?

La mayoría de los divertículos epifrénicos surgen por un mecanismo de pulsión debido a un trastorno motor esofágico que determina un efecto barrera y ocasiona la herniación mucosa y submucosa a través de un punto débil de la capa muscular. La manometría intraluminal esofágica y la videorradiología resultan importantes en la valoración de estos pacientes ya que definen las características del trastorno funcional, así como la verdadera relación entre los síntomas del paciente y el divertículo. El tratamiento quirúrgico está indicado en los sujetos sintomáticos, más aún si se han producido complicaciones respiratorias. La toracotomía posterolateral izquierda, seguida de diverticulectomía, cardiomiotomía esofágica y antirreflujo, ha sido considerada la técnica quirúrgica de elección. La miotomía esofágica debe sobrepasar, en sentido proximal, el cuello del divertículo y, en sentido distal, debe progresar 1¿2cm en la pared gástrica. El abordaje laparoscópico ha ganado numerosos adeptos, pues se ha mostrado tan seguro y eficaz como la vía abierta y suma las ventajas de la cirugía mínimamente invasiva (AU)

The majority of epiphrenic diverticula arise due to a peristaltic mechanism caused by an oesophageal motor disturbance that establishes a barrier effect and causes mucosal and submucosal herniation through a weak point in the muscular layer. Intraluminal oesophageal manometry and video-radiology are important in assessing these patients, since they define the characteristics of the functional disorder, as well as the true relationship between the symptoms of the patient and the diverticulum. Surgical treatment is indicated in symptomatic patients, more so if there are respiratory complications. Left posterolateral thoracotomy followed by diverticulotomy, oesophageal cardiomyotomy and anti-reflux have been considered the surgery technique of choice. Oesophageal myotomy must go beyond, in a proximal direction, the neck of the diverticulum, and, in a distal direction, must progress 1¿2cm into the gastric wall. The laparoscopic approach has won many followers since it has been shown to be both safe and effective as open surgery, adding to the advantages of minimally invasive surgery (AU)
