RESUMO
BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is a common procedure, but it poses challenges in patients with surgically altered gastrointestinal anatomy (SAGA). Alternative techniques like single-balloon enteroscopy (SBE), double-balloon enteroscopy (DBE), or push enteroscopy (PE) have been used, albeit with potential complications. Limited Latin American data exists on ERCP complications in SAGA patients. Our goal is to describe complications of ERCP in SAGA at a national referral institution. METHODS: Retrospective, single-center cohort study. All SAGA ERCP procedures performed at the Gastrointestinal Endoscopy Department of the National Institute of Medical Sciences and Nutrition Salvador Zubirán from January 2008 to May 2023 were included. Extracted data from records included procedure specifics, endoscope type, success, and complications. Complications were evaluated during procedure and 28-day post-procedure and classified using the AGREE system. RESULTS: A total of 266 procedures in 174 patients were included, 74% were women, and the median age was 44 years. Predominant modified anatomy was Roux-en-Y biliary reconstruction (79%), followed by Whipple procedure (13%) and subtotal gastrectomy with Roux-en-Y reconstruction (6.0%). The main indications were cholangitis with stricture (31%), stricture (19%), and cholangitis (19%). DBE was used in 89%, PE in 7.5%, and SBE in 3.4%. Success rates were 77% endoscopic, 72% technical, and 69% therapeutic; in 30%, the procedure was unsuccessful. Complications happened in 18% of cases, most commonly cholangitis (7.5%), followed by perforation (2.6%) and hemorrhage (1.9%). According to the AGREE classification, 10.9% were grades 1 and 2, 6.4% were grade 3, and 0.4% were grade 4 complications. No significant differences emerged between groups with and without complications. Procedures increased over time, but complications and unsuccessful procedures remained stable. CONCLUSION: ERCP complications align with international data, often not requiring invasive treatment. Enhanced exposure to such cases correlates with fewer complications and failures. Prospective studies are essential to identify complication and failure predictors.
RESUMO
Background: Cirrhosis is a public health threat associated with high mortality. Alcoholic Liver Disease (ALD) is the leading cause in Latin America and Metabolic Associated Fatty Liver Disease (MAFLD) in western countries. In Mexico, ALD and chronic Hepatitis C Virus infection (HCV) were the most frequent aetiologies during the past decades. We aimed to describe the trends in the aetiologies of cirrhosis in a middle-income country. Methods: We performed a retrospective cohort study including patients diagnosed with cirrhosis between 2000 and 2019 from six different tertiary care hospitals in central Mexico. We collected information regarding cirrhosis etiology, year of diagnosis, hepatocellular carcinoma development, liver transplantation, and death. We illustrated the change in the tendencies of cirrhosis aetiologies by displaying the proportional incidence of each etiology over time stratified by age and gender, and we compared these proportions over time using chi square tests. Findings: Overall, 4,584 patients were included. In 2019, MAFLD was the most frequent cirrhosis etiology (30%), followed by ALD (24%) and HCV (23%). During the study period, MAFLD became the leading etiology, ALD remained second, and HCV passed from first to fourth. When analysed by gender, ALD was the leading etiology for men and MAFLD for women. The annual incidence of HCC was 3·84 cases/100 persons-year, the median survival after diagnosis was 12·1 years, and seven percent underwent LT. Interpretation: Increased alcohol consumption and the obesity epidemic have caused a transition in the aetiologies of cirrhosis in Mexico. Public health policies must be tailored accordingly to mitigate the burden of alcohol and metabolic conditions in developing countries. Funding: None.
