The authors are reporting three cases of cerebral arteriovenous malformations which underwent surgical treatment using the operating microscope under mannitolization without hypotensive anesthesia.

The double pylorus is a fistulous communication between gastric antrum and duodenal bulb. It appears to be an acquired lesion in the majority of cases. Upon routine endoscopic procedures, it is frequently seem to occur in males who are either alcoholics, diabetics, those with chronic renal failure, chronic lung disease. If it is no developing complications such as septal rupture, double pylorus is well response to medical treatment. A 51-year-old man who had been taking medication over a long period for the chronic bronchitis was admitted to this hospital because of epigastric soreness and indigestion for 1 month. Endosopic findings showed two large openings of the pyloric channel and gastric ulcer in the channel. We thought that this case was an acquired lesion reasult of repeated gastric ulcer. We report a case of double pylrous with the brief review of literatures.
