ABSTRACT
BACKGROUND: Continuing education is essential for health professions and online courses can be a good way for professional development. AIM: To describe the experience with online courses for continuing education in hepatology and gastroenterology and to analyze their educational impact. MATERIAL AND METHODS: A three years' experience in courses on liver diseases and digestive tract is described. Their curricular design, methodology, and the educational impact was analyzed using the four levels of the Kirkpatrick's model. RESULTS: On average, there were 321 students per course (2015-2017). 94% were Chilean and 6% from abroad (20 countries). In the educational impact analysis, in level 1 "reaction": 93% said that the course fulfilled their expectations and 92% would recommend it. In level 2 "learning": 42% approved the courses. Level 3 "behavior" was not evaluated and level 4 "organizational change" highlighted that the traditional face-to-face continuing education model of Chilean Gastroenterology Society (SChG) changed to full distance model in these three courses, with 1284 students from South America, Asia and Europe, in a 3-years-period. Additionally, these programs were included in the Medical Society of Santiago (SMS) continuing education agenda. CONCLUSIONS: The alliance between the SMS and the SChG generated on line courses that meet the educational needs of physicians and medical students, with excellent results and student perception.

BACKGROUND: Currently, most liver units use the Child-Pugh (CP) or the Model for End-Stage Liver Disease (MELD) scores to establish survival prognosis among patients with liver cirrhosis. Which classification is superior, is not well defined. AIM: To compare CP and MELD classification scores to predict survival among adult patients with liver cirrhosis in Chile. MATERIAL AND METHODS: Follow-up of 137 consecutive adult patients with liver cirrhosis aged 59 ± 12 years (55% women). The diagnosis was reached by clinical, laboratory and image studies at three different centers of Santiago. Patients were staged with CP and MELD classification scores at baseline and followed over a period of 12 months. The predictive capacity of the scores for survival was analyzed using a multivariate statistical analysis (Kaplan-Meier curves). RESULTS: The most common etiology was alcohol (37.9%). The actuarial survival rate was 79.6% at 12 months of follow-up. When comparing groups with areas under curve of receiver operating characteristic curves (AUROC), there was no statistically significant difference in survival between less severe and advanced disease, assessed with both survival scales. The AUROC for MELD and CP were 0.80 and 0.81, respectively. CONCLUSIONS: This clinical study did not find a statistically significant difference between the two classifications for the prediction of 12 months survival in patients with cirrhosis.

AIM: To build a consensus among Chilean specialists on the appropriate management of patients with nonalcoholic fatty liver disease (NAFLD) in clinical practice. METHODS: NAFLD has now reached epidemic proportions worldwide. The optimal treatment for NAFLD has not been established due to a lack of evidence-based recommendations. An expert panel of members of the Chilean Gastroenterological Society and the Chilean Hepatology Association conducted a structured analysis of the current literature on NAFLD therapy. The quality of the evidence and the level of recommendations supporting each statement were assessed according to the recommendations of the United States Preventive Services Task Force. A modified three-round Delphi technique was used to reach a consensus among the experts. RESULTS: A group of thirteen experts was established. The survey included 17 open-ended questions that were distributed among the experts, who assessed the articles associated with each question. The levels of agreement achieved by the panel were 93.8% in the first round and 100% in the second and third rounds. The final recommendations support the indication of lifestyle changes, including diet and exercise, for all patients with NAFLD. Proven pharmacological therapies include only vitamin E and pioglitazone, which can be used in nondiabetic patients with biopsy-proven nonalcoholic steatohepatitis (the progressive form of NAFLD), although the long-term safety and efficacy of these therapies have not yet been established. CONCLUSION: Current NAFLD management is rapidly evolving, and new pathophysiology-based therapies are expected to be introduced in the near future. All NAFLD patients should be evaluated using a three-focused approach that considers the risks of liver disease, diabetes and cardiovascular events.

Liver transplantation is an excellent therapeutic option for terminal liver disease. During the last decades the results of liver transplantation have improved significantly with a patient survival rate of nearly 90% at one year and 80% at 5 years of follow-up. The main indications for liver transplantation include: end-stage liver disease associated to cirrhosis, acute liver failure, and hepatic tumors (mainly hepatocarcinoma). The absolute contraindications for a transplant are less frequent than in the past, and include: severe co-morbidity (cardiac or pulmonary), sepsis, advanced HIV disease and extra-hepatic malignancy. This document presents a Consensus of the main groups performing liver transplantation in Chile, about its indications and contraindications. It also reviews general aspects of liver transplantation, including the selection and referral of liver transplant candidates, allocation of organs and the evaluation of severity of liver disease.

BACKGROUND: Acute variceal bleeding in cirrhotic patients is an emergency with a high risk of rebleeding and death. Endoscopic procedures such as sclerotherapy or banding, combined or not with drugs such as octreotide could be considered. AIM: To assess the value of octreotide in the control of acute variceal bleeding. PATIENTS AND METHODS: Ninety-two patients were randomized into three groups: endoscopic therapy plus octreotide 50 microg/h bolus and continuous infusion for 5 days (n=36); octreotide (same dosage) (n=13) and endoscopic therapy only (banding and/or sclerotherapy) (n=43). RESULTS: Haemostasis at 24 hours was achieved in 97% of patients with combined treatment, 69% of patients receiving octreotide, and 93% of patients with endoscopic therapy (p=0.2). Three patients with combined treatment, four patients receiving octreotide and eight patients with endoscopic therapy, rebled during the first five days (p=0.15). The mean of blood units transfused was similar in the three groups. No differences were observed in hospital days and side effects. At 42 days of follow up, eight patients with endoscopic therapy, one patients with combined therapy and 2 patients receiving octreotide, died (p=NS). CONCLUSIONS: Octreotide is useful in the management of acute variceal bleeding. The absence of important side effects, renders it as a safe adjuvant treatment associated with endoscopic treatment.

BACKGROUND: The success of orthotopic liver transplantation (OLT) has resulted in its widespread use for different liver diseases. AIM: To report our 8 years experience with adult OLT at Clinica Alemana de Santiago. PATIENTS AND METHODS: In all transplantations done at the center, we recorded patient's overall data and survival, postoperative medical and surgical complications and causes of death. RESULTS: Between November 1993 and September 2001, 51 consecutive OLT were performed in 44 patients (22 females, median age 45 years old). Thirty eight patients presented with chronic and 6 with acute or sub-acute liver failure. Cryptogenic cirrhosis and hepatitis C infection were the most common causes for OLT. Postoperative bleeding and extrahepatic biliary complications were seen in 17.6 and 21.5% of cases respectively. Acute rejection, bacterial infections, CMV infection or disease and post OLT hemodialysis were the most common medical complications (51, 31, 19.6 and 19.6% of cases respectively). The overall 1 and 5 years survival rates were 80% and 73% respectively. Considering exclusively the last 22 OLT performed since January 1999, the 1 year survival rate has improved to 91%. CONCLUSIONS: Liver transplantation in Chile provides a good long term survival with acceptable morbidity, due to a multidisciplinary approach management. The survival rates have improved over the last few years probably due to better surgical techniques, ICU care and immunosuppression. These overall results are comparable with those from other Centers in developed countries.
