Utility of abdominal ultrasound for diagnosis of hepatic steatosis in patients with morbid obesity.

Metabolic dysfunction-associated fatty liver disease is the most common cause of liver disease in our environment. The gold standard for diagnosis continues to be liver biopsy, although, since it is an invasive test, the most commonly used test for the initial diagnosis of steatosis is abdominal ultrasound. We present the results on the diagnostic utility of ultrasound for the detection of steatosis in the population of morbidly obese patients who underwent bariatric surgery from 2004 to 2019 in our centre.

Hematoma post-endoscopic retrograde cholangiopancreatography.

Endoscopic retrograde cholangiopancreatography (ERCP) is one of the most frequently performed procedures in the treatment of biliary-pancreatic diseases. Hematoma after ERCP is an infrequent and highly serious complication. We present three cases with hepatic hematoma after a CPRE.

Relación de los factores demográficos e higiénico-dietéticos con la patología hallada en las colonoscopias ambulatorias realizadas en un centro del Servicio Castellano y Leonés de Salud / Relationship of demographic and dietary hygiene factors with the pathology found in outpatient colonoscopies performed in a Castilla y León Health Service center

Introducción: el cáncer colorrectal (CCR) es un tumor muy frecuente en términos de incidencia y mortalidad. Su patogenia se ha relacionado con diversos factores ambientales y hereditarios. Objetivos: analizar la asociación de edad, sexo y factores dietéticos con el diagnóstico de adenomas y CCR. Métodos: se realizó un estudio descriptivo prospectivo con los pacientes del Área Sanitaria de León que se sometieron a una colonoscopia ambulatoria entre 09/09/2012 y 30/06/2013. Mediante un formulario autoadministrado se recogieron datos sociodemográficos, tóxicos y dietéticos usando un cuestionario alimentario de frecuencia semicuantitativo. Se analizaron las diferencias en el diagnóstico según los datos sociodemográficos e higiénico-dietéticos, con análisis multivariante mediante regresión logística por pasos hacia delante. Resultados: se recogieron datos de 1390 pacientes cuya edad media fue de 57 (15) años; de ellos, el 47,8 % eran varones. Se diagnosticaron CCR en el 5 % de los pacientes y pólipos en el 20,4 % (9,4 % de adenomas de alto riesgo (AAR)). El hallazgo de pólipos y AAR fue más frecuente en los varones (26,9 % vs. 14,5 % y 12,6 % vs. 6,3 %, respectivamente (p < 0,001)). La edad media fue significativamente superior en los pacientes que presentaban pólipos (56.51 (15.45) vs. 63.22 (12.69) años; p < 0,001). En la población que refirió un consumo diario de carnes procesadas se duplicaba la proporción de pólipos detectados (2,9 % vs. 6,7 %; p = 0,02). Aquellos pacientes que consumían alcohol diariamente tenían mayor incidencia de pólipos frente al consumo ocasional y los abstemios (32 % vs. 20 % vs. 18,6 %; p = 0,002). Conclusiones: la edad se relacionaba con un mayor riesgo de pólipos, AAR y CCR. Los varones también tenían más riesgo de pólipos y AAR. El consumo de alcohol, carnes rojas y procesadas incrementaba el riesgo de pólipos. (AU)

Background: colorectal cancer (CRC) is one of the most frequent tumors in terms of incidence and mortality. Several elements, both inherited and environmental, have been related with its pathogenesis. Aims: to analyze the influence of age, gender and nutritional factors on the diagnosis of colonic polyps and CRC. Methods: a prospective, descriptive study over outpatients from the Health Area of León who took a colonoscopy between 09/09/2012 and 06/30/2013. Patients were asked to fill a semiquantitative food frecuency questionnaire with data such a sociodemographic, toxic and dietetic facts. Differences in diagnosis according to sociodemographic and hygiene-dietetic data were analyzed with a multivariate analysis by forward stepwise logistic regression. Results: data were collected from 1390 patients. Mean age was 57.88 (15.17) years and 47.8 % were male. CRC was diagnosed in 5 % of colonoscopies, and polyps in 20.4 %, with 9.4 % of them being HRA. Risk of polyps and HRA was higher in males (26.9 % vs 14.5 %) and (12.6 % vs 6.3 %), respectively (p < 0.001). Mean age was significantly higher in patients who presented polyps (56.51 (15.45) vs 63.22 (12.69) years; p < 0.001). Among the group who reported intake of smoked and salted food, the risk of polyps doubled (2.9 % vs 6.7 %, p = 0.002). In relation to alcohol intake we found that subjects with daily alcohol consumption showed a higher incidence of polyps whe compared to occasional drinkers and teetotallers (32 % vs 20 % vs 18.6 %, p = 0.002) Conclusions: age correlated with higher risk of polyps, HRA and CRC. Moreover, male gender also was associated with a high risk of polyps and HRA. Alcohol and red and processed meat intake increased polyp risk. (AU)

Hallazgos de la endoscopia digestiva alta en pacientes con obesidad mórbida candidatos a cirugía bariátrica / Upper endoscopy findings in obese morbid patients candidates for bariatric surgery

INTRODUCCIÓN: El índice de masa corporal se ha relacionado con la presencia de patología digestiva. El objetivo del estudio fue analizar los hallazgos endoscópicos y la histología gástrica de pacientes con obesidad mórbida candidatos a cirugía bariátrica en nuestro medio. MÉTODOS: Se incluyeron de manera retrospectiva los pacientes intervenidos de cirugía bariátrica en el Hospital de León desde marzo 2005 hasta abril 2013. Se recogieron los hallazgos de la endoscopia digestiva alta y la histología antral. Se estudió si el índice de masa corporal (IMC) estaba relacionado con los hallazgos de la gastroscopia o la presencia de Helicobacter pylori. RESULTADOS: Se incluyeron 194 pacientes. El 48,7 y el 78,9% de los pacientes presentaron alguna alteración en la endoscopia o en la biopsia antral, respectivamente. Tres pacientes presentaron úlcera gástrica péptica, demorándose la intervención hasta la curación. El 63,9% de los pacientes presentaron infección por H. pylori. La presencia de H. pylori y los hallazgos endoscópicos no se relacionaron con el IMC. CONCLUSIÓN: La patología gastroesofágica es frecuente en obesos mórbidos, y aproximadamente la mitad de los pacientes tenían algún tipo de alteración en la endoscopia. La realización de una gastroscopia e investigar la infección por H. pylori previa a la cirugía es necesario con el fin de descartar patología potencialmente susceptible de contraindicar o demorar la intervención

INTRODUCTION: Body mass index has been associated with the presence and severity of various gastrointestinal symptoms. The aim of the study was to analyze the endoscopic findings and gastric histology of morbidly obese candidates for bariatric surgery. METHODS: We retrospectively included patients undergoing bariatric surgery at the Hospital de León from March 2005 to April 2013. The findings of upper gastrointestinal endoscopy and antral histology were collected. The relationship of body mass index (BMI) with gastroscopy findings and the presence ofHelicobacter pylori were assessed. RESULTS: A total of 194 patients were included. An abnormality on endoscopy or antral biopsy was found in 48.7% and 78.9% of the patients, respectively. Three patients had gastric peptic ulcer, and consequently the intervention was postponed until healing. H. pylori infection was found in 63.9% of the patients. The presence of H. pylori and endoscopic findings were not related to BMI. CONCLUSION: Gastroesophageal disease is common in morbidly obese patients and approximately half of the patients had some kind of alteration on endoscopy. Gastroscopy and H. pylori testing prior to surgery is required to rule out disease that could delay or contraindicate surgery

SHORT-TERM CHANGES IN MACRONUTRIENT INTAKE IN MORBIDLY OBESE PATIENTS UNDERGOING BILIOPANCREATIC DIVERSION: A LONGITUDINAL STUDY.

INTRODUCTION: biliopancreatic diversion (BPD) has been shown to be one of the most effective techniques for losing weight, although nutritional education also might play an important role. Our aim was to determine the effect of the combination of a nutrition educational program (NEP) and BPD on changes in the intake of energy and macronutrients after the surgery. METHODOLOGY: this longitudinal study included all patients eligible for BPD who filled in a dietary record. Two assessments were performed: six weeks before and twelve months after surgery. The nutrition educational program was given two weeks after surgery by a registered dietitian and a 3-day food record was collected for further analysis at both of the assessments. RESULTS: 68 patients were included. The percentage of excess weight loss was 60.76% (SD 14.50%). A year after the surgery there was a reduction of energy (-602.27 kcal [SD 930.19 kcal], p < 0.001), fat (-41.70 g [SD 77.87 g], p < 0.001), percentage of fat (-4.79% [SD 11.38%], p = 0.001), and an increase in the percentage of protein (+ 2.72% [SD 7.10%], p = 0.002). A lower consumption of fat, especially of polyunsaturated fatty acids, was observed in the patients that achieved the nutritional recommendations and in the super-obese patients. CONCLUSION: The combination of NEP and BPD resulted in an improvement in the nutritional profile, with a reduction of fat and maintenance of the protein intake.

Relationship Between Diet and Body Composition After Biliopancreatic Diversion.

BACKGROUND: Biliopancreatic diversion (BPD) has been shown to be one of the most effective techniques for losing weight, although the relationship between body composition and diet after the procedure is not well known. Our aim was to assess dietary changes and their effects on body composition. METHODOLOGY: This longitudinal study included all patients eligible for BPD who had undergone body composition analysis. Two assessments were performed: 6 weeks before and 1 year after surgery. Nutritional education was given after surgery by a registered dietitian, and dual energy X-ray absorptiometry was performed and a 3-day food record was collected for further analysis at both of the visits. RESULTS: Forty-six patients were included. The percentage of excess of weight loss was 61.03 % (SD 14.01 %), which was statistically different by gender (p = 0.045). The percentage of subjects reporting a low daily protein consumption of less than 60 g and 1.2 g/kg of ideal body weight (IBW)/day was 15.2 % before surgery and 19.6 % at 12 months (p = 0.006). The weight loss was mainly of fat mass (FM). There were differences of body composition by gender before and after surgery. A simple correlation analysis showed a significant association between daily energy intake and FM (g) only before surgery (p = 0.030), and also between daily protein intake (expressed as total g) and lean body mass (LBM) 12 months after surgery (p = 0.018), but no association was found with achieved protein goal. CONCLUSION: BPD enhanced by nutritional education seems to improve its results by achieving an adequate weight loss, preserving LBM, decreasing FM, and guaranteeing an appropriate protein intake.

Factores asociados al nivel de limpieza colónica medido mediante la escala de Boston en la práctica clínica habitual / Factors associated with colon cleansing measured with the Boston scale in routine clinical practice

INTRODUCCIÓN La escala de Boston es una herramienta útil para estandarizar el nivel de preparación en la colonoscopia. El objetivo del trabajo fue analizar el grado de limpieza de la colonoscopia y los factores asociados a este en la práctica clínica habitual. MATERIAL Y MÉTODOS: Se incluyeron las colonoscopias realizadas desde enero hasta junio de 2013. Los motivos de exclusión fueron: edad < 15 años, antecedentes de cirugía colónica, enfermedad inflamatoria intestinal o hemorragia digestiva activa. Los parámetros estudiados en relación con el grado de limpieza (mediante la escala de Boston) fueron: la edad, el sexo, la indicación, el turno de la exploración (mañana o tarde), la procedencia (ambulante o ingresado) y los hallazgos encontrados. RESULTADOS: Se analizaron 947 exploraciones, excluyéndose 297. El 5,8% (38/650) de las exploraciones fueron incompletas, el 50% por falta de preparación. La edad media fue de 61,27 años (DS: 16,1), siendo el 51,8% mujeres. La distribución del nivel de preparación fue: 0-3 6,3%; 4-5 12,6%; 6-7 30,6%; 8-9 50,4%, siendo la media 7,04 (DS: 2,03). En el análisis multivariante los factores asociados a una mejor preparación que resultaron estadísticamente significativos fueron: una edad menor, el turno de tarde y el régimen ambulatorio. El porcentaje de pólipos en pacientes con una escala de Boston 5 fue de 10%, frente al 27,8% en pacientes con una puntuación > 5 (p = 0,014). CONCLUSIÓN: En la práctica clínica se obtiene un grado de preparación aceptable en el 80% de los pacientes. Los pacientes con más edad, aquellos que se realizan la colonoscopia de mañana o estando ingresados serían candidatos a medidas para mejorar el grado de preparación

INTRODUCTION: The Boston scale is useful to standardize colon cleansing at colonoscopy. The aim of this study was to analyze the degree of preparation before colonoscopy and the factors associated with cleansing in routine clinical practice. MATERIAL AND METHODS: We included colonoscopies performed from January to June 2013. Exclusion criteria were age < 15 years, a history of colon surgery, inflammatory bowel disease, and active gastrointestinal bleeding. The standard preparation was CitraFleet(R). The parameters related to the degree of bowel cleansing (using the Boston scale) were age, sex, indication, colonoscopy shift (morning or afternoon), patient origin (outpatient or hospitalized), and colonoscopy findings. RESULTS We analyzed 947 colonoscopies, with exclusion of 297. A total of 5.8% (38/ 650) of the colonoscopies were incomplete, 50% due to lack of preparation. The mean age of the patients was 61.27 years (SD: 16.1), and 51.8% were women. The distribution of the Boston scale was 0-3 in 6.3%, 4-5 in 12.6%, 6-7 in 30.6%, and 8-9 in 50.4%, with a mean 7.04 (SD: 2.03). On multivariate analysis, the factors statistically associated with better preparation were younger age, afternoon colonoscopy and the outpatient setting. The percentage of polyps in patients with a Boston scale score ≤ 5 was 10% compared with 27.8% in patients with a score > 5 (P = .014). CONCLUSION: In clinical practice, 80% of patients had an acceptable level of preparation. Older patients, those undergoing colonoscopy in the morning and hospitalized patients would be candidates for measures to improve the degree of colonic preparation

Older patients, those undergoing colonoscopy in the morning and hospitalized patients would be candidates for measures to improve the degree of colonic preparation.

[Upper endoscopy findings in obese morbid patients candidates for bariatric surgery]. / Hallazgos de la endoscopia digestiva alta en pacientes con obesidad mórbida candidatos a cirugía bariátrica.

INTRODUCTION: Body mass index has been associated with the presence and severity of various gastrointestinal symptoms. The aim of the study was to analyze the endoscopic findings and gastric histology of morbidly obese candidates for bariatric surgery. METHODS: We retrospectively included patients undergoing bariatric surgery at the Hospital de León from March 2005 to April 2013. The findings of upper gastrointestinal endoscopy and antral histology were collected. The relationship of body mass index (BMI) with gastroscopy findings and the presence of Helicobacter pylori were assessed. RESULTS: A total of 194 patients were included. An abnormality on endoscopy or antral biopsy was found in 48.7% and 78.9% of the patients, respectively. Three patients had gastric peptic ulcer, and consequently the intervention was postponed until healing. H.pylori infection was found in 63.9% of the patients. The presence of H.pylori and endoscopic findings were not related to BMI. CONCLUSION: Gastroesophageal disease is common in morbidly obese patients and approximately half of the patients had some kind of alteration on endoscopy. Gastroscopy and H.pylori testing prior to surgery is required to rule out disease that could delay or contraindicate surgery.

Insulin resistance and metabolic syndrome are related to non-alcoholic fatty liver disease, but not visceral adiposity index, in severely obese patients.

The visceral adiposity index (VAI) is a marker of visceral fat distribution and dysfunction. Visceral adiposity is related to nonalcoholic fatty liver disease (NAFLD); however, there is some controversy regarding the association between VAI and NAFLD.The aim of this study was to analyse the relationship between VAI and NAFLD and to describe the related factors in severely obese patients. A total of 139 patients who underwent bariatric surgery were included in this cross-sectional study. Liver biopsy was performed during surgery. Univariate and multivariate analysis were conducted to study the features related to VAI. A univariate analysis was conducted to identify which factors were associated with liver histology. In the univariate analysis, steatosis, liver inflammation, non-alcoholic steatohepatitis (NASH) and fibrosis were associated with VAI. In the multivariate analysis, only HOMA (Beta: 0.06; p < 0.01) and metabolic syndrome (Beta: 1.23; p < 0.01) were related to VAI. HOMA, the presence of metabolic syndrome, and waist circumference (WC) were statistically related to the NAFLD activity score (NAS score): HOMA: 0-2: 5.04; 3-4: 7.83; > or = 5: 11,32; p < 0.01; MS: 0-2: 37 %; 3-4: 33.3 %; > or = 5: 76%; p < 0.01; WC: 0-2: 128.7 cm; 3-4: 130.7; > or = 5: 140.6; p < 0.01). For the prediction of NASH (NAS score > or = 5), the AUROC curve were 0.71 (CI 95 %: 0.63-0.79) for VAI and 0.7 (CI 95 %: 0.62-0.78) for WC. In conclusion, HOMA, WC and metabolic syndrome are related to liver histology in patients with severe obesity. In the multivariate analysis, VAI was associated with HOMA and metabolic syndrome, but not with liver histology.
