RESUMO

BACKGROUND: Metabolic surgery is the most effective therapeutic strategy for the management of type 2 diabetes (T2DM). Several preoperative clinical factors have been associated with T2DM remission after metabolic surgery. However, other potential predictors remain unexplored. AIM: To assess the role of basal (pre-surgery) clinical and biochemical parameters in T2DM remission after metabolic surgery. METHODS: A prospective study including 98 patients with T2DM undergoing metabolic surgery was performed. Clinical, anthropometric, and biochemical data were collected at baseline and 1 year following metabolic surgery. RESULTS: Patients without T2DM remission 1 year after metabolic surgery presented a longer duration of diabetes and higher glycated hemoglobin (HbA1c) levels; a higher percentage of these subjects were using insulin therapy, antihypertensive drugs, and lipid-lowering therapies before metabolic surgery, compared to those patients with T2DM remission. A lower percentage of T2DM remission after metabolic surgery was observed among patients with hypertension/hypercholesterolemia before surgery, compared to those patients without hypertension/hypercholesterolemia (51.7 % vs 86.8 %, p < 0.001, and 38.5 % vs 75 %, p < 0.001, respectively), and among patients with longer duration of diabetes (≥5 years vs <5 years; 44.4 % vs 83 %, respectively; p < 0.001). In the logistic regression model, diabetes duration, basal HbA1c, and the presence of hypertension and hypercholesterolemia before surgery were inversely related to T2DM remission following metabolic surgery, after adjusting for sex, age, waist circumference, and type of surgery. CONCLUSIONS: In a cohort of patients with obesity and T2DM, preoperative hypertension and hypercholesterolemia, together with a longer diabetes duration and higher HbA1c concentrations, were independent predictors of T2DM persistence after metabolic surgery.

RESUMO

Resumen Introducción: La cirugía bariátrica no está exenta de complicaciones. Para minimizar dichas complicaciones es importante optimizar al paciente antes de la cirugía. Dicha optimización se basa fundamentalmente en la realización de dieta preoperatoria. Dentro de los múltiples tipos de dietas, la dieta de muy bajo valor calórico (DMBVC) es cada vez más utilizada. El objetivo de este estudio es analizar los resultados del empleo de la DMBVC en el preoperatorio de cirugía bariátrica. Método: Estudio observacional de una serie de 100 casos en los que se empleó la DMBVC como optimización preoperatoria. Se analizaron el grado de cumplimiento de la dieta, la opinión de los pacientes, la pérdida de peso preoperatoria y las complicaciones postoperatorias. Resultados: La pérdida de peso preoperatoria media fue de 10,2 kg y la disminución media del IMC fue de 4,8. En cuanto al grado de seguimiento, el 68% refirió que la cumplió estrictamente, el 22% manifestó un buen grado de seguimiento con alguna transgresión ocasional, el 8% reportó un mal seguimiento y el 1% la abandonó precozmente. No se presentaron efectos adversos significativos. En cuanto a la técnica quirúrgica, en ningún caso el volumen hepático dificultó la cirugía, con un 0% de conversiones y un tiempo medio operatorio de 60 min. En el postoperatorio inmediato se registraron un 4% de sangrado y un 1% de reintervención por hemoperitoneo. Conclusiones: Las DMBVC son sencillas de utilizar, con escasos efectos adversos, bien toleradas durante un periodo limitado de tiempo, obteniendo una adecuada pérdida ponderal preoperatoria.


Abstract Introduction: Bariatric surgery may have some complications. To minimize such complications is important to optimize the patient before surgery. Such optimization is based primarily on the performance of preoperative diet. Among the many types of diets, very low caloric diet (VLCD) is increasingly used. The aim of this study is to analyze the results of the use of VLCD preoperative bariatric surgery. Method: Observational study of a series of 100 cases in which the DMBVC was used as a preoperative optimization. The degree of compliance with the diet, the opinion of patients, preoperative weight loss and postoperative complications were analyzed. Results: The mean preoperative weight loss was 10.2 kg and the average BMI decrease of 4.8. As for the degree of compliance, 68% said that the strictly fulfilled, 22% follow up with a good degree occasional transgression, mistracking 8% and 1% abandoned early. No significant adverse effects occurred. Regarding the surgical technique, in any case difficult surgery liver volume, with 0% conversion and an average operating time of 60 min. In the immediate postoperative period 4% cases of reoperation for bleeding and 1% hemoperitoneum were reported. Conclusions: DMBVC are simple to use, with few adverse effects, well tolerated for a limited period of time, obtaining adequate preoperative weight loss.

RESUMO

Resumen Las neoplasias retroperitoneales suponen un reto para el profesional sanitario, tanto en el diagnóstico como en el tratamiento. Caso clínico: Varón de 56 años diabético tipo 2. Acude por edema en extremidad inferior derecha y parestesias. Se realiza ecografía doppler con resultados de trombosis venosa profunda y conglomerado adenopático. En TAC abdominal se observa gran masa retroperitoneal que engloba paquete vasculonervioso iliaco derecho. Se realiza vaciamiento ganglionar con resultado inicial de hamartoma. Se practica cirugía de resección de la masa y ligadura de la vena iliaca externa trombosada preservando la arteria iliaca. Anatomía patológica intraoperatoria sugestiva de sarcoma y definitiva de liposarcoma. Reingresa por shock hipovolémico y rotura de la arteria iliaca derecha. Se realiza ligadura y bypass femoro-femoral izquierdo-derecho. Al alta es derivado a oncología, falleciendo a los 6 meses. Discusión: El sarcoma es el tumor primario más frecuente a nivel retroperitoneal (15%). De difícil diagnóstico y tardío tratamiento, suelen ser asintomáticos hasta que debutan como una masa y clínica de compresión local o afectación de estructuras vasculonerviosas. El TAC es la prueba diagnóstica de elección. El tratamiento del tumor localizado es la cirugía; la radioterapia y quimioterapia se reservan para tumores irresecables o de alto grado.


Abstract Retroperitoneal neoplasias may be a diagnostic and therapeutic challenge for the clinician. Case report: A 56 year old male with prior history of type 2 diabetes consults with right inferior limb edema and paresthesias. He was diagnosed of deep vein thrombosis and lymph node conglomerate by ultrasound. A CT scan was performed, observing great retro peritoneal mass enclosing vascular and nervous structures. An initial histological diagnosis of hamartoma was made. Surgery was scheduled to remove the tumour, ligation of thrombosed external iliac vein and the external iliac artery was preserved. Intraoperative histological findings suggested sarcoma, definite studies showed presence of high grade liposarcoma. Two weeks after the intervention, the patient presents in hypovolemic shock due to rupture of the right external iliac artery. Emergent ligation of the artery and femorofemoral bypass was performed, with adequate postoperatory recovery. The patient was discharged and continued adjuvant oncology treatment and was exitus six months later. Discussion: Sarcomas are the most frequent primary retroperitoneal tumours. They are difficult to diagnose and often have untimely treatment. Sarcomas tend to be asymptomatic, or present with local compression symptoms, affecting vascular and nervous structures. CT scan is the gold standard for diagnostic imaging. Treatment requires a multidisciplinary approach, surgical resection as the main therapy; radio and chemotherapy represents a solution for irresectable or high grade malignancies.

RESUMO

UNLABELLED: Morbid obesity is a risk factor for numerous diseases including liver disease with an incidence of hepatic steatosis from 70 to 80%. Although surgical treatment is effective in reducing weight, its effects on the liver have not been established convincingly. We report 2 cases of patients with bariatric surgery and who had a fulminant hepatic failure resulting in death. METHODS: case N.º 1: a 36-year-obesity intervened in 1995 with VBG with BMI 52.5 to reganancia weight back after revision surgery is performed in 2009 performed distal gastric bypass. Case N.º 2: 42 Woman surgery for obesity in 2009 by distal gastric bypass with a BMI of 51 and placement of prophylactic Composix kugel midline mesh. After 3 years with good weight loss, presents abscess wall and enterocutaneous fistula he was surgically intervene. extracting mesh, identifying themselves two fistulas in alimentary and common intestinals loops that are removed and new anastomosis was performed. RESULTS: case N.º 1: at 2 months of revision surgery, tje patient starts vomiting secondary to stenosis of gastrojejunostomy anastomosis and symptoms of progressive jaundice, ascites and encephalopathy fulminant hepatic failure resulting in death. Case N.º 2: in the immediate postoperative period starts increased drainage of debit and rise of liver enzymes cytolysis and coagulopathy. It reinterviene on suspicion of anastomotic leak and abdominal Sepsis, developing fulminant hepatic failure with coagulopathy and encephalopathy is treated by MARS system, and died within 4 hours of the onset of therapy. CONCLUSIONS: although current surgical techniques of bariatric surgery are considered quite safe, there have been cases of hepatic failure, unclear whether this would relate to the progression of a preexisting steatohepatitis, or may have other predisposing factors related to surgery. Treatments available, the emergency orthotopic liver transplantation is one of the best interventions. For our patients the outcome was fatal triggering the death of both. In both cases presented a septic shock with positive ascitic fluid cultures to multiresistant microorganisms, and both had revision surgery. Unfortunately the factors that can influence that occur after bariatric surgery such complications, and probably will be grounds for future studies are unknown.


La obesidad mórbida es un factor de riesgo para numerosas enfermedades, incluidas las enfermedades hepáticas, siendo la incidencia de esteatosis hepática de un 70 a 80%. Aunque el tratamiento quirúrgico es eficaz en la reducción del peso, sus efectos sobre el hígado no se han establecido convincentemente. Presentamos dos casos de pacientes intervenidas de cirugía bariátrica y que presentaron un fallo hepático fulminante con resultado de muerte. Material y método: caso clínico n.º 1: mujer de 36 años intervenida de obesidad en 1995 con gastroplastia vertical anillada con IMC 52,5 que tras reganancia ponderal posterior se realiza cirugía de revisión en 2009, realizándose by-pass gástrico distal. Caso clínico n.º2: mujer de 42 años intervenida de obesidad en 2009 mediante by-pass gástrico distal con IMC de 51 y colocación de malla profiláctica de composix kugel midline. A los tres años con buena pérdida ponderal presenta absceso de pared por fístula enterocutánea y se interviene quirúrgicamente, extrayendo malla, identificándose dos fístulas en asa alimentaria y común que se extirpan y se realizá nueva anastomosis. Resultados: caso clínico n.º1: a los dos meses de la cirugía de revisión inicia cuadro de vómitos secundarios a estenosis de anastomosis gastroyeyunal que se trata mediante dilatación, y cuadro de ictericia progresiva, ascitis y encefalopatía por fallo hepático fulminante con resultado de muerte. Caso clínico n.º2: en el postoperatorio inmediato inicia incremento del debito del drenaje, así como ascenso de enzimas de citolisis hepática y coagulopatía. Se reinterviene por sospecha de fuga anastomótica y sepsis abdominal, desarrollando fallo hepático fulminante con coagulopatía y encefalopatía que se trata mediante sistema MARS, falleciendo a las cuatro horas de la instauración de la terapia. Conclusiones: si bien las técnicas quirúrgicas actuales de cirugía bariátrica se consideran bastante seguras, se han presentado casos de fallo hepático, sin estar claro si esto se relacionaría con la progresión de una esteatohepatitis preexistente, o bien pudiera haber otros factores favorecedores relacionados con la cirugía. De los tratamientos disponibles, el trasplante hepático ortotópico de emergencia es una de las mejores intervenciones. En el caso de nuestras pacientes la evolución fue fatal, desencadenando la muerte de ambas. Ambos casos presentan un shock séptico con cultivos de líquido ascítico positivo a microorganismos multirresistentes, y ambas presentaron cirugías de revisión. Lamentablemente se desconocen los factores que pueden influir en que tras la cirugía bariátrica ocurran este tipo de complicaciones, y probablemente será motivo de estudios futuros.
