[Syndrome caused by extrinsic compression of the celiac trunk (apropos of 4 cases)].

On the basis of angiographic documentations the Authors report on 4 observations (3 men and 1 woman) of extrinsic compression of the coeliac trunk symptomatologically evidenced through abdominal pain attacks. All the patients were treated surgically by resection of the median arcuate ligament of the diaphragm. In one case distal pancreatic resection was also performed on account of accompanying chronic pancreatitis. The long-term results were excellent in 3 cases, and good in 1. The diagnosis and surgical indication were made possible after repeated biochemical and instrumental investigations in order to exclude different pathologies (vascular, biliary, pancreatic, gastrointestinal) which might account for the reported symptoms. There is still discussion on the unresolved problem of the pathogenesis of the pain, as well as on surgical tactic and the advisability of completing resection of the arcuate ligament by sympathicectomy or coeliac ganglionectomy.
