Core Tip

Core tip: Refractory gastroparesis (GP) has been identified as a chronic debilitating disease. After failure of diet and prokinetic drugs for treatment of refractory GP only surgical options are left. Because of the limited available treatment options and frequent failure of medical therapy, botulinum toxin (BT) injection in the pylorus might offer clinical value in GP. Currently available evidence is not strong enough to support the recommendation of this procedure in all patients with refractory GP; but promising results have been seen as most patients have noticed symptomatic improvement. Although BT injections were successful in some GP patients, the role of BT remains undetermined. We addressed the position of botulinum toxin in the spectrum of available treatments for refractory GP. Continuing other treatment modalities after BT may improve the results.
