    Notes: Summary We report the color Doppler ultrasonography features of arteriovenous malformation (AVM) of the pancreas, a very rare disease. The patient was a 52-year-old man with congenital AVM of the pancreas and a duodenal ulcer that had been resistant to medication. Endoscopic color Doppler ultrasonography (color Doppler EUS) revealed many abnormal color signals showing pulsatile wave form at the portion of the duodenal wall involving the duodenal ulcer. Extracorporeal color Doppler ultrasonography revealed a mosaic-like color signal, caused by turbulent flow, in the portal trunk. Angiography demonstrated a vascular network with extensive proliferation at the pancreatic head and early portal filling. It is possible that the pancreatic AVM had caused the duodenal ulcer. Color Doppler EUS can be a useful modality for detection of vessel abnormalities of the gastrointestinal tract.

    Notes: Abstract We review several Japanese reports regarding pylorus-preserving pancreatoduodenectomy (PPPD), including our previous survey of a totll of 313 patients who had undergone PPPD as of September, 1989 at 82 major medical facilities. PPPD in Japan was initially performed in 1981 in a patient with leiomyosarcoma of the pancreas. Because of extensive growth of the tumor, right hemicolectomy was also performed and the alimentary tract was reconstructed in the new Billroth I procedure. Many reports have since indicated that PPPD yields favorable results. The patient characteristics ranged widely, from benign diseases to malignancies, including cancer of the pancreas. The use ofPPPD is how increasing both in Japan and in the United States and Europe. The operative techniques, reconstruction methods, morbidity, mortality, survival, and pathophysiology of PPPD in Japan are reviewed in comparison with these factors in the Whipple resection.
