Background: Despite the relatively high prevalence of gastroparesis and functional dyspepsia, the aetiology and pathophysiology of these disorders remain incompletely understood. Similarly, the diagnostic and treatment options for these two disorders are relatively limited despite recent advances in our understanding of both disorders.
Purpose: This manuscript reviews the advances in the understanding of the epidemiology, pathophysiology, diagnosis, and treatment of gastroparesis and functional dyspepsia as discussed at a recent conference sponsored by the American Gastroenterological Association (AGA) and the American Neurogastroenterology and Motility Society (ANMS). Particular focus is placed on discussing unmet needs and areas for future research.

Introduction: Gastroparesis is a debilitating gastroduodenal disorder for which gastric peroral endoscopic myotomy (GPOEM) has emerged as an efficacious treatment option. However, response to GPOEM varies between 50% and 80%, such that preoperative predictors of treatment success are needed to guide patient selection.
Methods: We performed a systematic review to identify predictors of clinical and functional response to GPOEM among adult patients with gastroparesis (PROSPERO: CRD42023457359).

Purpose: Gastrointestinal (GI) dysfunction is common in critically ill patients and associated with poor outcomes. There is a lack of standardised methods for daily monitoring of GI function. COSMOGI aimed to develop a Core Outcome Set (COS) for daily monitoring of GI function to improve consistency and comparability in future studies in critically ill patients.

Diabetic gastroparesis (DGP), a prevalent complication of diabetes, is characterized by delayed gastric emptying and inflammation. The dorsal motor nucleus of the vagus (DMV) plays a crucial role in modulating gastric function via the vagus nerve. Neuregulin 1 (NRG1), which is present in the DMV and influences the autonomic nervous system, has an unclear role in DGP.

To establish a consensus on the definition and management of idiopathic gastroparesis, international experts (selected by neurogastroenterology and motility societies and initiated by the Rome Foundation) devised 144 statements using the Delphi method, with at least 80% agreement required. This consensus defined idiopathic gastroparesis as the presence of symptoms associated with delayed gastric emptying in the absence of mechanical obstruction. Nausea and vomiting were identified as cardinal symptoms.

Diabetic gastrointestinal neuropathy is a diabetes-related complication, associated with a complex interplay of hyperglycemic damage, autoimmune responses, oxidative stress, gastrointestinal hormones, and vascular insufficiency. Patients with diabetes should be monitored and therapeutic intervention introduced to prevent neuropathy due to diabetes prior to "the point of no return". Determining gastric bioelectrical activity by body surface gastric mapping may be a promising option to monitor diabetic gastrointestinal neuropathy.
