RESUMO

OBJECTIVE: The objective of this study was to compare the total procedure time and task-specific execution time in gastric bypass using a three-dimensional (3D) versus two-dimensional (2D) imaging system. MATERIALS AND METHODS: This study was a prospective and randomized clinical trial. Forty obese patients were randomized into two groups: gastric bypass with 3D imaging system or with conventional 2D system. The primary endpoint was operative time during manual gastrojejunal anastomosis. Data collection was carried out on demographics, comorbidities, operative time in three stages, and complications. The same surgeon performed all surgeries. Two patients were excluded because technical issues were encountered for viewing their videos during the trial. RESULTS: A total of 20 patients in the Laparoscopic Gastric Bypass (LGB) 3D group and 18 in the LGB 2D group were analyzed. There were no significant differences in the pre-operative data. The average procedure time was 16.5 min lower in the 3D group versus the 2D group. Execution time for specific tasks was not statistically significant, except for the gastrojejunal anastomosis, which is routinely performed as a manual anastomosis in our surgery group. There was no complication intra- or post-operative. CONCLUSIONS: The use of a 3D imaging system for laparoscopic gastric bypass was associated with a shorter total operative time, especially for the hand-sewn gastrojejunal anastomosis, compared with the 2D imaging system. OBJETIVO: Comparar el tiempo total del procedimiento y de tareas específicas en bypass gástrico laparoscópico (BGL) utilizando sistemas de imagen 3D y 2D.


MÉTODO: Estudio prospectivo, aleatorizado, con 40 pacientes obesos divididos en dos grupos: BGL 2D o 3D. El objetivo principal fue medir el tiempo al realizar la gastroyeyunoanastomosis manual. La recolección de datos incluyó comorbilidad, demografía, tiempo operatorio en tres fases (formación de reservorio, gastroyeyunoanastomosis y yeyunoyeyunoanastomosis) y complicaciones posoperatorias. El mismo cirujano realizó los procedimientos. Se excluyeron dos pacientes por incapacidad para abrir el video. RESULTADOS: Se analizaron 20 pacientes en el grupo 3D y 18 en el grupo 2D. No hubo diferencias significativas en los datos preoperatorios. El tiempo promedio del procedimiento fue menor en el grupo 3D que en el 2D en 16,5 minutos. El tiempo de ejecución para realizar tareas solo fue significativo al realizar la gastroyeyunoanastomosis. No hubo ninguna complicación intraoperatoria ni posoperatoria. CONCLUSIONES: El uso de un sistema de imagen 3D se asoció con un menor tiempo quirúrgico total, en especial para la gastroyeyunoanastomosis manual, en comparación con el sistema de imagen 2D.

RESUMO

INTRODUCTION: Bariatric surgery has been shown to be effective in reducing weight and has benefits, such as lowering blood pressure. An increase in urinary sodium excretion has been suggested as a possible mechanism. This study explored changes in sodium excretion and their correlation with blood pressure after Roux-en-Y gastric bypass. MATERIALS AND METHODS: This study was conducted on 28 obese participants with body mass index (BMI) of 44.54 ± 7.81 kg/m2 who underwent gastric bypass. Before surgery and at the third and sixth months after gastric bypass, blood pressure, urinary sodium concentration, 24-hour (24-h) urinary sodium excretion, and fractional excretion of sodium were evaluated. In addition, serum sodium and potassium levels were determined. Nonparametric tests were used to analyze the data. RESULTS: Blood pressure decreased after surgery and remained at low levels over the 3- and 6-month periods. The urinary sodium concentration increased at 3 months after surgery; however, the 24-h urinary sodium excretion and urine volume decreased. Interestingly, although some associations between variables were observed, significant correlations between the 24-h urinary sodium excretion and the systolic, diastolic, and mean blood pressures were found. In addition, the urine volume was higher in the sixth month than in the third month following surgery. CONCLUSIONS: In the months immediately following surgery, a low-salt and low-volume diet favors decreases in urine volume and 24-h urinary sodium excretion. In addition, in the sixth month after surgery, an association between blood pressure and 24-h urinary sodium excretion was observed.

RESUMO

Resumen Antecedentes: El íleo biliar es una rara complicación de la colecistitis crónica litiásica que representa del 1 al 3% de los casos de oclusión intestinal. Primera vez descrito por Bartolin en 1654, el íleo biliar ocurre por obstrucción crónica del conducto cístico y necrosis de la vesícula biliar, lo que puede desarrollar una fistula colecisto-entérica. Rigler en 1941 describió la tríada clásica del íleo biliar. Caso clínico: Mujer de 56 años de edad con diagnóstico de insuficiencia hepática que súbitamente presentó distención abdominal con ausencia de evacuaciones y canalización de gases. La tomografía abdominal mostró datos que sugieren el diagnóstico de oclusión intestinal, por lo que se realizó laparotomía exploradora con presencia de distención de asas. Se retiraron 2 litos por medio de enterolitotomía; evolución posquirúrgica adecuada hasta lograr estabilización hemodinámica y alta hospitalaria. Conclusiones: La presencia de íleo biliar es una rara causa de colusión intestinal que requiere de tratamiento quirúrgico para su resolución. Ee necesita un alto nivel de sospecha para su diagnóstico y manejo.


Abstract Background: Gall-stone ileus is a weird complication of the lithiasic cholecyst since it represents only 1 to 3% of the bowel obstuccion cases. It was described for the first time by Bartoin in 1654, the gall-stone ileus happens due to a cronic obstruccion in the cistic duct than causes gallbladder necrosis and a bile enteric fistula. In 1941, Rigler described the classic triad for the gall-stone ileus. Clinical case: A 56-year-old woman that had a diagnosis of hepatic failure, suddenly presented abdominal distension, constipation and obstipation. The abdominal tomography showed data that suggested a bowel occlusion, therefore, we performed an exploratory laparotomy and found distension of the bowel loops and the presence of three gall stones, that were removed with enterolitotomy. The pacient had a good posquirurgic evolution and was discharged from hospital. Conclusions: The gall-stone ileus is a rare cause for bowel occlusion that requires surgical treatment; it needs a high level of suspicion for its diagnoses and management.

RESUMO

UNLABELLED: The objectives of this study are to provide a description of the demographic, anthropometric characteristics and metabolic abnormalities in children with early-onset (< 10 years) and of very-early-onset obesity (< 5 years). We also evaluate the diagnostic ability using the definition of metabolic syndrome (MS) according to different criteria. METHODS: It is a retrospective, case-control, cross-sectional, multicenter study. A total of 10 Pediatric Endocrinology Units in different Spanish hospitals were involved. A group of 469 children with early-onset obesity and another group of 30 children with very early-onset obesity were studied. The control group consisted of 224 healthy children younger than 10 years. Anthropometric and analytical determination of carbohydrates metabolism parameters and the lipid profile were performed. RESULTS: The presence of metabolic alterations associated with obesity in children and adolescents in Spain is remarkable, either on their own, or encompassed within the definition of MS. This prevalence increases substantially when considering the peripheral resistance to insulin action as a diagnostic criterion. It also shows how children who could not be diagnosed with MS according to the definition provided by the International Diabetes Federation (IDF) due to age below 10 years, these alterations are already present in a remarkable percentage. In fact, metabolic abnormalities are already present in the very-early-onset obese children ( <5 years). CONCLUSION: In Spanish children there are metabolic alterations associated with obesity in the infant-juvenile stages alone or encompassed within the definition of MS,and are already present at earlier ages.


Los objetivos de este estudio son, realizar una descripción de las características demográficas, antropométricas y de las alteraciones metabólicas de niños atendidos por obesidad resaltando las características aquellos casos de obesidad de inicio temprano (< 10 años) y los de inicio precoz (< 5 años), y evaluar la capacidad diagnóstica de la definición de síndrome metabólico (SM) según diferentes criterios. Métodos: Es un estudio retrospectivo, caso-control, transversal, multicéntrico. Han participado un total de 10 Unidades de Endocrinología Pediátrica de diferentes hospitales españoles con un grupo de 469 niños con obesidad de inicio temprano y otro grupo de 30 niños con obesidad de inicio precoz. El grupo control estuvo constituido por 224 niños sanos menores de 10 años. Se realizó una valoración antropométrica y determinación analítica de parámetros del metabolismo de los hidratos de carbono y lipidograma. Resultados: La presencia de alteraciones metabólicas asociadas a la obesidad en la etapa infanto-juvenil en España es notable, de forma aislada, o englobada bajo la definición de SM. La prevalencia de éste aumenta sustancialmente cuando se considera la resistencia periférica a la acción de la insulina como criterio diagnóstico. Se demuestra cómo en niños menores de 10 años, dichas alteraciones están presentes en un porcentaje reseñable, y se encuentran las primeras alteraciones metabólicas ya en niños obesos < 5 años. Conclusión: En los niños españoles existen alteraciones metabólicas asociadas a la obesidad en la etapa infanto- juvenil de forma aislada o englobada bajo la definición de SM, y ya están presentes a edades precoces.

RESUMO

Introducción. La ataxia por deficiencia de vitamina E es causada por mutaciones en el gen TTPA . Está caracterizada por ataxia, arreflexia, temblor cefálico, pérdida de la propiocepción, Babinsky, disdiadococinesia, retinitis pigmentosa y cardiomiopatía. Caso clínico. Se trató de una paciente del sexo femenino de 11 años, padres consanguíneos, valorada por dolor y parestesias en miembros inferiores, disartria y problemas para escribir y masticar. El examen físico mostró fuerza distal disminuida, hiperreflexia, Babinsky, disminución en la propiocepción, pie cavo bilateral, dismetría, disdiadococinesia y Romberg positivo. El estudio para ataxia de Friedreich resultó normal, aunque presentó bajos niveles de a-tocoferol y se identificó una mutación homocigota c.205-1G>C en el gen TTPA . Se inició tratamiento con vitamina E con lo que mostró mejoría. Conclusiones. Ante la presencia de manifestaciones parecidas a la ataxia de Friedreich se sugiere evaluar niveles plasmáticos de α-tocoferol y realizar estudios genéticos confirmatorios. El tratamiento con vitamina E disminuye los síntomas en los afectados y los presintomáticos no desarrollan manifestaciones del trastorno. Se han reportado pocos casos en Latinoamérica. En esta paciente se encontró una mutación en estado homocigoto fuera de las áreas de mayor prevalencia. Dichos hallazgos clínicos pueden indicar que la mutación c.205-1G>C se asocia con un cuadro severo.


Background. Ataxia with vitamin E deficiency is a disorder caused by mutations in the TTPA gene. Common symptoms include ataxia, areflexia, head titubation, loss of proprioception, Babinsky sign, dysdiadochokinesia, pigmentary retinopathy and cardiomyopathy. Case report. The patient was the first child of consanguineous parents. She presented at 10 years of age due to bilateral lower limb pain and numbness and difficulty in speech, writing and chewing. Physical examination showed dysarthria, diminished distal strength, hyperreflexia, positive Babinsky sign, decreased proprioception, pes cavus, dysmetria, dysdiadochokinesia and positive Romberg sign. Genetic screening for the Friedreich's ataxia gene resulted negative, α-tocopherol levels were low and TTPA gene sequentiation detected the homozygous mutation c.205-1G >C in intron 1. Treatment was initiated with vitamin E, showing improvement of symptoms. Conclusions. The presence of Friedreich's ataxia-like phenotype suggests the need to perform tests of plasma levels of α-tocopherol and the confirmatory genetic test. Treatment with vitamin E decreases symptoms in both affected and presymptomatic individuals. Few patients have been described in America, and our case showed a homozygous mutation outside of high-prevalence areas. Clinical findings of this patient and a previous case would indicate that the c.205-1G>C mutation is associated with severe symptoms.
