Article Synopsis
- The 2013 Asia-Pacific consensus on managing hilar cholangiocarcinoma was updated due to new evidence regarding endoscopic treatment for malignant hilar biliary obstruction (MHBO).
- A review of literature using a PICO framework led to the creation of consensus statements and key concepts, with expert approval through the modified Delphi method.
- The final recommendations address diagnosis, biliary drainage strategies, recurrent obstruction management, cholecystitis post-stenting, and pre-stenting treatments, but emphasize that they should complement, not replace, multidisciplinary decisions for individual patients.
Distal biliary strictures (DBS) are common and may be caused by both malignant and benign pathologies. While endoscopic procedures play a major role in their management, a comprehensive review of the subject is still lacking. Our consensus statements were formulated by a group of expert Asian pancreatico-biliary interventional endoscopists, following a proposal from the Digestive Endoscopy Society of Taiwan, the Thai Association for Gastrointestinal Endoscopy, and the Tokyo Conference of Asian Pancreato-biliary Interventional Endoscopy.

Methods: A total of 501 patients with reflux esophagitis were randomized into one of the following two treatment regimens: 40 mg esomeprazole plus 300 mg rebamipide daily (combination therapy group) or 40 mg esomeprazole daily (monotherapy group). We used a symptom questionnaire that evaluated heartburn, acid regurgitation, and four upper gastrointestinal symptoms.
Background And Aim: A major reason impeding the growth of endoscopic ultrasound (EUS) in Asia is the lack of training availability. We aimed to prospectively evaluate the effectiveness of a short-term structured EUS training program in improving the knowledge and skill of EUS among trainees.
Methods: The study was conducted in six workshops in six countries including Sri Lanka, Pakistan, Thailand, Vietnam, Singapore and Philippines, within a year.
In Asia, the incidence of pancreatic cancer in some countries has been increasing. Owing to most cases being diagnosed late, prognosis for pancreatic cancer remains dismal. It is clear that the future for pancreatic cancer lies in early detection.

Methods: All patients who underwent EUS examination for the evaluation of pancreatic cystic lesions in six Asian centres were included in the study.
Results: Of 298 patients with pancreatic cysts who underwent EUS, 132 (44.
