RESUMEN
BACKGROUND: Since the publication in 2009 of the Guidelines on the Diagnosis and Treatment of Irritable Bowel Syndrome of the Asociación Mexicana de Gastroenterología (2009 Guidelines), there have been significant advances in our knowledge of the epidemiology, pathophysiology, diagnosis, and treatment of this disease. AIMS: To present a consensus review of the most current knowledge of IBS, updating the 2009 Guidelines by incorporating new internationally published scientific evidence, with a special interest in Mexican studies. METHODS: The PubMed literature from January 2009 to March 2015 was reviewed and complemented through a manual search. Articles in English and Spanish were included and preference was given to consensuses, guidelines, systematic reviews, and meta-analyses. Statements referring to the different aspects of the disease were formulated and voted upon by 24 gastroenterologists employing the Delphi method. Once a consensus on each statement was reached, the quality of evidence and strength of recommendation were determined through the GRADE system. RESULTS: Forty-eight statements were formulated, updating the information on IBS and adding the complementary data that did not appear in the 2009 Guidelines regarding the importance of exercise and diet, diagnostic strategies, and current therapy alternatives that were analyzed with more stringent scientific vigor or that emerged within the last 5 years. CONCLUSIONS: We present herein a consensus review of the most relevant advances in the study of IBS, updating and complementing the 2009 Guidelines. Several studies conducted in Mexico were included.

BACKGROUND: Acute pancreatitis (AP) etiology and frequency vary in relation to geographic region. AIMS: To determine the etiology, frequency, and mortality of AP in a Mexican population. PATIENTS AND METHODS: We carried out a prospective study of first episode AP patients over a period of 6 years. RESULTS: A total of 605 patients with a mean age of 40 years were included in the study. Sixty-four percent of them presented with overweight and/or obesity determined through BMI. Etiology was biliary in 66.60%, it was due to alcohol consumption in 15.90%, hypertriglyceridemia in 7.80%, it was post-endoscopic retrograde cholangiopancreatography (ERCP) in 2.10%, and was undetermined in 7.20%. Pancreatic infection was suspected in 70 patients and they underwent CT-guided fine needle aspiration. Thirty-two of those patients were diagnosed with pancreatic infection in which Staphylococcus spp was the most common microorganism. Overall mortality was 5.00% (2.60% < 30 years and 10.00% > 70 years). Necrosis, pancreatic infection, and mortality were more frequent in the cases in which etiology was due to alcohol ingestion. CONCLUSIONS: The most frequent AP etiology was biliary, but that caused by alcohol presented with more complications. Overall mortality was 5.00% and was higher in the elderly patients.
