SUMMARYBackground: Population-based data on gastro-oesophageal reflux in Latin America are lacking. Aim: To assess gastro-oesophageal reflux symptom prevalence, clinical spectrum and association with the atypical symptoms in our country. Methods: Gastro-oesophageal reflux self-report questionnaires validated at Mayo Clinic, USA, were submitted to a sample of 1000 residents (aged 18-80 years) from 17 representative geographical areas of Argentina. The samples were selected and stratified according to age, gender, geographical areas and size of town of residence provided by the Argentine Bureau of Statistics and Census.

Endoscopic argon plasma ablation therapy is useful in the management of bleeding from colonic angiodysplasia.

Biliary sampling at ERC using a dedicated basket provided a significantly higher sensitivity for cancer detection than brushing; presampling stricture dilation significantly increased sensitivity.

Biliary complications were more frequent after LDLT compared with DDLT. Endoscopic treatment of anastomotic biliary strictures was successful in a minority of patients after LDLT, in contrast with DDLT. Most biliary leaks were successfully treated at endoscopy after LDLT or DDLT.
