Methods: The questionnaire was created and developed through a literature review of current gastroparesis works of literature by the scientific committee of Asian Neurogastroenterology and Motility Association.
Results: A total of 490 doctors from across Asia (including Bangladesh, China, Hong Kong, Indonesia, Japan, Malaysia, Myanmar, the Philippines, Singapore, South Korea, Taiwan, Thailand, and Vietnam) participated in the survey. Gastroparesis is a significant gastrointestinal condition. However, a substantial proportion of respondents was unable to give the correct definition and accurate diagnostic test. The main reason for lack of interest in diagnosing gastroparesis was "the lack of reliable diagnostic tests" (46.8%) or "a lack of effective treatment" (41.5%). Only 41.7% of respondents had access to gastric emptying scintigraphy. Most doctors had never diagnosed gastroparesis at all (25.2%) or diagnosed fewer than 5 patients a year (52.1%).
Conclusions: Gastroparesis can be challenging to diagnose due to the lack of instrument, standardized method, and paucity of research data on normative value, risk factors, and treatment studies in Asian patients. Future strategies should concentrate on how to disseminate the latest knowledge of gastroparesis in Asia. In particular, there is an urgent need to estimate the magnitude of the problems in high risk and idiopathic patients as well as a standardized diagnostic procedure in Asia.
METHODS: : A multidisciplinary task force comprising 24 voting members and 5 non-voting facilitators from across Asia was convened. Experts were divided into four working groups addressing clinical evaluation, non-pharmacological management, pharmacological management, and specialized investigations and treatments. Targeted literature reviews were performed, and statements were developed using a structured Delphi process with iterative anonymous voting. The certainty of the evidence and the strength of the recommendations were graded using the GRADE framework.
RESULTS: : Thirty-nine consensus statements were developed, covering clinical assessment and stepwise management. Recommendations emphasize comprehensive symptom assessment, early evaluation of disease severity and psychosocial impact, and prioritizing constipation treatment in patients with overlapping GI symptoms and those with pelvic floor damage. Initial management includes lifestyle modification and conventional laxatives, with treatment response assessed within 4 weeks. For inadequate response, treatment optimization, combination or switching of laxatives, and newer agents are recommended. The algorithm also highlights appropriate use of anorectal physiologic testing and biofeedback therapy for functional defecatory disorders. Surgical interventions are reserved for highly selected patients after comprehensive evaluation.
CONCLUSIONS: : This ANMA/APAGE consensus provides a practical, algorithm-based framework to improve management of chronic constipation across diverse Asian healthcare settings.
