Aortoesophageal fistula as a fatal complication of esophageal perforation.

Aortoesophageal fistula is a very rare cause of upper gastrointestinal bleeding, however its interest lies in the high mortality rate associated with it. Due to this, early diagnosis and treatment of this entity is essential to increase survival. The typical symptoms known as the Chiari´s triad are only present in 45% of reported cases. We present the case of a patient with upper gastrointestinal bleeding due to an aortoesophageal fistula as well as the importance of endoscopic use for its differential diagnosis.

Medium/long term evaluation of lipid profile after bariatric surgery (gastric bypass versus sleeve gastrectomy).

INTRODUCTION: Bariatric surgery aims to reduce weight and resolve the comorbidities associated with obesity. Few studies have assessed mid/long-term changes in lipid profile with sleeve gastrectomy versus gastric bypass. This study was conducted to assess and compare changes in lipid profile with each procedure after 60 months. METHODS: This was an observational, retrospective study of analytical cohorts enrolling 100 patients distributed into two groups: 50 had undergone gastric bypass (GBP) surgery and 50 sleeve gastrectomy (SG) surgery. Total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglyceride (TG) levels were measured before surgery and at 1, 6, 12, 24, 36, 48, and 60 months. Weight loss and the resolution of dyslipidemia with each of the procedures were also assessed. RESULTS: Ninety-five of the 100 patients completed follow-up. At 60 months, TC and LDL levels had significantly decreased in the BPG group (167.42 ±â€¯31.22 mg/dl and 88.06 ±â€¯31.37 mg/dl, respectively), while there were no differences in the SG group. Increased HDL levels were seen with both procedures (BPG: 62.69 ±â€¯16.3 mg/dl vs. SG: 60.64 ±â€¯18.73 mg/dl), with no difference between the procedures. TG levels decreased in both groups (BPG: 86.06 ±â€¯56.57 mg/dl vs. SG: 111.09 ±â€¯53.08 mg/dl), but values were higher in the BPG group (P < .05). The percentage of overweight lost (PSP) was higher in the BPG group: 75.65 ±â€¯22.98 mg/dl vs. the GV group: 57.83 ±â€¯27.95 mg/dl. CONCLUSION: Gastric bypass achieved better mid/long-term results in terms of weight reduction and the resolution of hypercholesterolemia as compared to sleeve gastrectomy. While gastric bypass improved all lipid profile parameters, sleeve gastrectomy only improved HDL and triglyceride levels.

Metástasis muscular de adenocarcinoma gástrico: A propósito de un caso y revisión de la literatura / Skeletal Muscle Metastasis from Gastric Adenocarcinoma: A Case Report and Review of the Literature

Resumen Los pacientes diagnosticados de adenocarcinoma gástrico pueden desarrollar metástasis hepáticas o carcinomatosis peritoneal, pero la presencia de metástasis musculares es extremadamente infrecuente, con muy pocos casos descritos. Presentamos a una paciente de 44 años con una tumoración dolorosa en miembro superior izquierdo. Fue tratada un año antes de un adenocarcinoma gástrico con cirugía y quimioterapia. Mediante pruebas de imagen y biopsia, se le diagnosticó metástasis muscular única de adenocarcinoma gástrico, siendo intervenida realizando exéresis quirúrgica.

Abstract Patients diagnosed with gastric adenocarcinoma may develop liver metastases or peritoneal carcinomatosis, but the presence of muscle metastases is extremely rare, with very few cases reported. We present a 44-year-old female patient with a painful tumor in her left upper limb. She was treated with surgery and chemotherapy for gastric adenocarcinoma a year before. By imaging tests and biopsy, she was diagnosed with a single muscle metastasis from gastric adenocarcinoma and underwent surgical exeresis.

Comportamiento de ghrelina en ayunas después de bypass gástrico y gastrectomía vertical: estudio de cohortes analítico / Fasting ghrelin levels after gastric bypass and vertical sleeve gastrectomy: An analytic cohort study

Antecedentes y objetivo: En el hipotálamo existen poblaciones neuronales involucradas en la regulación de la ingesta, destacando la ghrelina como hormona orexígena (estimula el apetito). Después de los diferentes procedimientos de cirugía bariátrica se han observado cambios en los niveles plasmáticos de ghrelina, siendo los resultados de los estudios contradictorios. Existen muchas lagunas en cuanto al papel que desempeña la ghrelina en el proceso de pérdida de peso después de cirugía bariátrica. Nuestro objetivo es describir el comportamiento de ghrelina en ayunas, comparando los cambios acontecidos en 2 técnicas quirúrgicas (bypass gástrico versus gastrectomía vertical) y su correlación con la pérdida ponderal. Pacientes y método: Estudio observacional de cohortes analíticas prospectivo, donde se incluyen 54 pacientes (27 por cada técnica quirúrgica) y un período de seguimiento de 12 meses. Se analizaron datos demográficos, datos antropométricos, comorbilidades, pérdida ponderal y evolución del comportamiento de ghrelina en ayunas. Resultados: Con ambas técnicas quirúrgicas el comportamiento de ghrelina acilada fue similar, sin diferencias significativas entre bypass gástrico y gastrectomía vertical. Con ambos procedimientos se produce un ascenso de ghrelina acilada al 5.o día y caída posterior, para luego ir ascendiendo hasta alcanzar valores superiores a los preoperatorios a los 12 meses. Este aumento en los niveles de ghrelina no afecta a la pérdida ponderal, ya que al año de la cirugía con las 2 técnicas quirúrgicas se alcanza un 30% de pérdida de peso. Conclusiones: Observamos un incremento de los niveles de ghrelina acilada en ayunas al año de seguimiento con ambas técnicas quirúrgicas, cuando existe una pérdida ponderal del 30%

Background and objective: Neuronal populations involved in the regulation of food intake, particularly the orexigenic (appetite-stimulating) hormone ghrelin, are found in the hypothalamus. Changes in plasma ghrelin levels have been observed following different bariatric surgery procedures, but the results from different studies are contradictory. Much remains unknown regarding the role of ghrelin in the weight loss process following bariatric surgery. Our objective was to describe the behaviour of fasting ghrelin levels, comparing the changes occurring between 2 different surgical techniques (gastric bypass versus vertical sleeve gastrectomy) and their correlation with weight loss. Patients and method: A prospective, observational, analytic cohort study of 54 patients (27 for each surgical technique) with a 12-month follow-up period. We analysed demographic data, anthropometric data, comorbidities, weight loss and evolution of fasting ghrelin. Results: The behaviour of acylated ghrelin was similar with the 2 surgical techniques, with no significant differences between gastric bypass and vertical sleeve gastrectomy. With both procedures, there was an increase in acylated ghrelin on day 5 and a subsequent decrease, and levels then gradually increased to reach values at 12 months that were higher than those reported preoperatively. This increase in ghrelin levels did not affect weight loss, since one year post-surgery, 30% weight loss was achieved with both types of surgery. Conclusions: We observed an increase in fasting acylated ghrelin levels at one year of follow-up with both surgical techniques, with 30% weight los
