Gastrointestinal endoscopy is a safe, efficient technique with minimal complications, and a useful diagnostic tool for the pediatric population. Under ideal conditions endoscopies for children should be performed by experienced pediatric endoscopists. In this study we report our experience with pediatric endoscopy at the general adult endoscopy unit in our hospital. Our goal is to quantify the number of endoscopies performed in children, as well as their indications and findings, the type of sedation or anesthesia used, and the time waiting for the test to occur. Our experience demonstrates that endoscopists in a general adult gastroenterology department, working together with pediatricians, may perform a relevant number of endoscopies in children in a fast, safe, effective manner.La endoscopia gastrointestinal es una técnica segura y eficiente con mínimas complicaciones, así como una útil herramienta diagnóstica en la población pediátrica. En condiciones ideales, las endoscopias en niños deberían ser realizadas por endoscopistas pediátricos experimentados. En este estudio reportamos nuestra experiencia en la realización de endoscopias pediátricas en la Unidad de Endoscopias general de adultos de nuestro hospital. El objetivo es cuantificar la cantidad de endoscopias realizadas en niños, así como las indicaciones y hallazgos de las mismas, el tipo de sedación o anestesia empleado y el tiempo de espera para la realización de la prueba. Nuestra experiencia demuestra que los endoscopistas de un servicio de gastroenterología general de adultos, en colaboración con pediatras, pueden realizar un número importante de endoscopias a niños, de forma rápida, segura y eficaz.

Background and Aims: Prevalence of non-alcoholic fatty liver disease (NAFLD) in developed countries is 30% in the general population and 50% in patients with type 2 diabetes mellitus (T2DM). The aim of this study was to compare the severity of NAFLD, as assessed by liver biopsy and using the non-invasive index NAFLD Fibrosis Score (NFS), in subjects with and without T2DM., Patients and Methods: The study sample consisted of 217 patients with biopsy-proven NAFLD. Anthropometric assessments, laboratory tests, histological criteria established by the Non-alcoholic Steatohepatitis Clinical Research Network (NASH CRN), and the NFS were recorded., Results: Patients with T2DM (n=36; 16.5%) had higher HOMA-IR values (6.3±3.6 vs. 3.3±2.4; p<0.0001), GGT levels (125.2±102.3 vs. 82.5±70.6IU/l; p<005), and NFS index (-0.6±0.2 vs. -1.8±0.1; p<0.001) than subjects with no T2DM. Patients with T2DM were found higher rates of NASH (72.2% vs. 48.6%; p<0.05), advanced steatosis (80.6% vs. 63%; p<0.05), and liver fibrosis (75% vs. 43.1%, p<0.05) than patients with no T2DM. Patients with T2DM also had higher NFS values (-0.6±1.2 vs. -1.8±1.8: p=0.01). A logistic regression analysis adjusting for age, gender and BMI showed a significant independent association between NASH and presence of T2DM (OR=4.2: 95% CI: 1.4-12.1; p=0.007). A second model adjusting for the same covariates showed T2DM to be an independent factor associated to advanced fibrosis (OR=4.1; 95% CI: 1.7-9.7)., Conclusion: Patients with T2DM have more advanced degrees of NAFLD and advanced fibrosis as assessed by liver biopsy and the NFS index. Particular attention should be paid to the study and monitoring of NASH in patients with T2DM., (Copyright © 2018 SEEN y SED. Publicado por Elsevier España, S.L.U. All rights reserved.)

Background: a prolonged non-alcoholic steatohepatitis (NASH) condition can lead to advanced stages of liver disease and the development of hepatocellular carcinoma., Aim: to evaluate analytical, anthropometric and dietary factors associated with the presence of fibrosis as this is the factor that most influences survival and evolution., Methods: seventy-six patients with liver biopsy-diagnosed non-alcoholic fatty liver disease (NAFLD) were included. Biopsies were scored considering the NASH criteria of Kleiner. Analytical, anthropometric and dietary (survey) parameters were obtained. NAFLD-FS is a non-invasive fibrosis index and was assessed for each patient. Leptin, adiponectin, resistin and TNF-alpha serum levels were determined., Results: fifty-six patients were male (73.7%) and the mean age was 44.5 ± 11.3 years of age (19-68). Thirty-nine (51.3%) (F1-F2: 84.6%; F3-4: 15.4%) patients had fibrosis in the liver biopsy. Seventeen females (85%) had fibrosis versus 22 males (39%), which was statistically significant by univariate analysis (p < 0.01). Patients with advanced fibrosis were older, with lower platelet counts, lower serum albumin, greater homeostatic model assessment insulin resistance (HOMA-IR), lower dietary lipids percentage, higher serum leptin levels and higher NAFLD Fibrosis Score (NAFLD-FS) values. This index had a negative predictive value of 98% and a positive predictive value of 60% for the detection of fibrosis. Variables independently associated with fibrosis (logistic regression) included male gender (protective factor) (0.09, 95% CI 0.01-0.7; p < 0.05) and HOMA-IR (1.7, 95% CI, 1.03-2.79; p < 0.05)., Conclusions: gender and HOMA-IR were the only independent factors associated with fibrosis. NAFLD-FS could be considered as an accurate scoring system to rule out advanced fibrosis.

Background: Biliary complications, a major source of morbidity after orthotopic liver transplantation (OLT), are increasingly being treated by endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic management has been shown to be superior to percutaneous therapy and surgery. Covered self-expandable metal stents (CSEMSs) may be an alternative to the current endoscopic standard treatment with periodic plastic stent replacement., Objective: To assess the safety and efficacy of temporary CSEMS insertion for biliary complications after OLT., Methods: From November 2001 to December 2009, the 242 OLT performed in 226 patients included 67 cases that developed post-OLT leaks or strictures (29.6%), excluding ischemic biliary complications. CSEMSs were used in 22 patients (33%), 18 male and 4 female, with an overall median age of 55 years (range, 29-69). In-house OLT patients underwent an index ERCP at 26 days (range, 8-784) after OLT. Their records were reviewed to determine ERCP findings, technical success, and clinical outcomes., Results: ERCP with sphincterotomy was performed in all 22 patients, revealing 18 with biliary strictures alone (82%), 3 with strictures and leaks (14%), and 1 with strictures and choledocholithiasis (4%). All strictures were anastomotic. All patients had 1-2 plastic stents inserted across the anastomosis (11 had prior balloon dilation); stones were successfully removed, for an initial technical success rate of 100% (22/22). CSEMSs, were placed at the second ERCP in 14 patients, at the third in 7, and at the fourth in 1. With a median follow-up of 12.5 months (range, 3-25) after CSEMS removal, 21/22 patients (95.5%) remain stricture free and one relapsed, requiring repeat CSEMS insertion. Four patients experienced pain after CSEMS insertion. At CSEMS removal, migration was noted in 5 cases, into either the distal duodenum (n=4) or the proximal biliary tree (n=1), and embedding was seen in 1 case. There were no serious complications; no patients needed hepatojejunostomy., Conclusions: ERCP is a safe first-line approach for post-OLT biliary complications. It was highly successful in a population with anastomotic leaks and strictures. The therapeutic role of ERCP to manage biliary complications after OLT in the long term is not well known. In our experience, the high rate (close to 95%) of efficacy and its relative safety allowed us to use CSEMS to manage refractory biliary post-OLT strictures. CSEMS insertion may preclude most post-OLT hepatojejunostomies., (Copyright © 2010 Elsevier Inc. All rights reserved.)
