XXXX : treatment guided by catheter probe US.

@entity1 @entity970 @entity751
BACKGROUND: The " @entity751 ," caused by migration of the internal bumper into the gastric walls, is a rare complication of @entity970 . The internal bumper becomes completely overgrown by gastric mucosa. Localization of internal bumpers in relation to the layers of the gastric wall was investigated with catheter probe US to define the optimal therapeutic strategy for @entity970 removal. METHODS: Eleven @entity1 with the @entity751 were encountered within 40 months. The internal bumper was localized endosonographically within the gastric and abdominal layers with a 20 MHz catheter US probe. In case of intramural localization, endoscopic extraction was attempted; extramurally located bumpers were removed surgically. OBSERVATIONS: In 8 @entity1 with an intramural internal bumper, endoscopic @entity970 removal was achieved without major complication. Mild bleeding after needle knife incision in one case was successfully treated by clip application. In the 3 remaining @entity1 with extragastric localization of the bumper, the @entity970 was surgically removed. CONCLUSION: The position of the internal bumper within the layers of the gastric and abdominal wall can be determined by EUS with high-resolution catheter probes, thereby indicating the appropriate therapeutic approach.
