Preserved Antral Contractions Measured by Wireless Motility Capsule Are Associated With Lower Response Rates to Gastric Per-Oral Endoscopic Myotomy in Patients With Idiopathic Gastroparesis.

Key Points

• The research aims to evaluate the relationship between antral contractions and response rates to G-POEM in idiopathic gastroparesis.
• Measured antral contractions using a wireless motility capsule
• Assessed response rates to gastric per-oral endoscopic myotomy (G-POEM)
• Compared characteristics of patients with preserved versus diminished contractions
• Preserved antral contractions were linked to lower G-POEM response rates
• Diminished contractions correlated with a positive response to G-POEM
• Preserved contractions might indicate sensory dysfunction rather than motor issues
