The multi-channelled pylorus.

The entity of multiple pyloric channels may be congenital but the majority are acquired lesions representing fistulae secondary to peptic ulcer disease in the pyloroduodenal region. The fistula usually joins the lesser curvature of the stomach with the superior aspect of the duodenal bulb. The multichannelled pylorus produces a characteristic radiological appearance on barium mean examination with a double or split barium column in the region of the pylorus. Four cases are described and illustrated.

Transcatheter vascular occlusion therapy with isobutyl 2-cyanoacrylate (bucrylate) for control of massive upper-gastrointestinal bleeding.

Transcatheter embolization with bucrylate, a tissue adhesive, was performed in 16 patients with massive upper-gastrointestinal bleeding. Control of arterial bleeding from the stomach was achieved in 6 of 8 patients, and from the duodenum in 3 of 4. Embolization of gastric veins resulted in temporary control of esophageal variceal bleeding in 3 of 4 patients. Histological study showed no evidence of bucrylate causing histotoxicity in 2 patients. Because bucrylate polymerizes rapidly, a localized vascular occlusion mimicking a surgical ligation is produced. Because collateral vessels are not occluded. localized tissue ischemia is unlikely. Tissue adhesives are, however, difficult to use.
