Expert Consensus on Multidisciplinary Diagnosis and Treatment of Gastroparesis in China (2025, Beijing)

Gastroparesis (GP) is a gastric motility disorder characterized by delayed gastric emptying in the absence of mechanical obstruction. This expert consensus covers aspects of GP etiology (diabetes, surgery, drug-induced, idiopathic, scleroderma, etc.), symptomatology, diagnosis (scintigraphic imaging, ultrasound contrast meal assessment, and radiopaque marker gastric motility testing), and treatment (pharmacological therapy, nutritional support, traditional Chinese medicine, and interventions targeting the pylorus, such as endoscopic surgery and surgical procedures). GP significantly impacts patients' psychological well-being and quality of life, potentially leading to psychological disorders such as anxiety and depression, and also imposes a heavy economic burden on patients and society. Therefore, this expert consensus advocates for the establishment of a multidisciplinary team diagnosis and treatment model, which will further standardize and optimize the diagnosis and treatment process of GP in our country and is crucial for improving patients' therapeutic outcomes and quality of life.
