Gastroparesis is a syndrome characterized by delayed gastric emptying with associated symptoms. Gastric emptying is a complex process and pyloric dysfunction may play a key role in select subsets of patients with gastroparesis. Diagnostic tests to measure pyloric physiology are now available and have the potential to be more widely used in clinical practice. Targeted therapies including botulinum toxin, transpyloric stent placement, surgical pyloroplasty and endoscopic pyloromyotomy have been developed. Data are emerging regarding efficacy and durability, but these therapies may play a prominent role in select patients with gastroparesis and pyloric dysfunction.
