Laser recanalization of pyloric stenosis: a guidewire-directed contact probe technique.
A variety of techniques has been used to relieve the obstructive symptoms of pyloric stenosis. Endoscopic dilatation using hydrostatic balloon dilators, multiple-diameter bougies, and electrocautery with a sphincterotome have been described. The neodymium yttrium aluminum garnet laser also has been used, with both noncontact and contact probes. We describe a new technique using a guidewire-directed contact probe for laser recanalization of pyloric stenosis in a patient with radiation-induced gastric outlet obstruction.
