RESUMO
BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is a relatively new surgical technique for the treatment of morbid obesity. It is unclear whether the volume of the gastric remnant can expand after surgery as a result of intraluminal pressure maintained over time. If this were the case, the increased volume could affect weight loss and the improvement in comorbidities. This study aims to assess the evolution of residual gastric volume (RGV) during the first year after LSG and its relationship with weight loss. MATERIAL AND METHODS: We conducted a prospective study of 112 patients who underwent LSG from February 2009 to December 2013. In order to measure the RGV after surgery, all patients were evaluated radiologically by an esophagogastroduodenal (EGD) transit at 1 and 12 postoperative months. RESULTS: All patients showed a significant reduction in BMI compared with the preoperative measurement (33.48 ± 5.78 vs. 50.54 ± 6.69 kg/m2; p < 0.001). Increased RGV was observed when comparing the results obtained by EGD transit at 1 (68.39 ± 25.89 cm3) and 12 postoperative months (122.58 ± 38.76 cm3; p < 0.001). There was no association between increase in gastric volume and weight loss at 1-year follow-up (r = 0.01; p = 0.910). CONCLUSIONS: The volume of the gastric remnant increased significantly during the first year after LSG. However, this increase was not associated with weight loss. Further prospective research with longer follow-up periods is needed to confirm or contrast the present results.

Aneurysm of the azygos vein is a rare cause of mediastinal mass that is normally detected radiologically in asymptomatic patients. In some cases a diagnosis is made by noninvasive methods, such as computed tomography and magnetic resonance. However, in the present case imaging revealed what appeared to be a solid mass. When the mass had been excised by thoracotomy, the histopathologic diagnosis was aneurysm of the azygos vein.

El aneurisma de la vena ácigos es una causa muy infrecuente de masa mediastínica y habitualmente se trata de un hallazgo radiológico en pacientes asintomáticos. Aunque en algunas ocasiones se puede llegar al diagnóstico por métodos no invasivos, como la tomografía computarizada y la resonancia magnética, en nuestro caso la imagen obtenida se asemejaba a una masa sólida. Se intervino a la paciente mediante toracotomía y se procedió a la exéresis de la tumoración. El diagnóstico histopatológico fue de aneurisma de la vena ácigos
